how to tell if your phone lcd screen is broken made in china

Mandy, ETS is obviously a company that you are connected to and this could easily be taken for spam. I think we can make an exception at this time since you are asking a good market research question that may be useful to many.

Having checked out your video, I personally will not use the aftermarket screen as a replacement for my X. It just doesn"t have what I expect for a $1000 USD phone. I recognize that $300 USD for a replacement is hefty but the aftermarket screen does not appear to have the quality that I would expect for my phone.

As an official phone repair provider who has been in the business for almost a decade, one unique question people ask when they visit our service centres to replace their phone screen is: "what"s the difference between original and copy phone screen?"

Well, the answer is, there are many differences between these two screens, which is mostly in their quality. And while “copy” phone screens are somewhat cheaper than the originals, it doesn’t justify the difference in quality. So, before you regret replacing your phone screen with a forbidden part, the tips below will tell you the critical differences between original and copy phone screens.

Generally, phone screens manufactured from your brand"s factory are the original ones while ‘Copy’screens are the ones designed and produced by third-party manufacturers and factories that are not related to your brand.

Many people usually like to go for copy screens because of their cheaper price. However, the "real" differences between original and copy screens lie in their quality, and here’s what you need to know about them.

One of the principal issues with "copied" phone screens and why it differs from the originals is touch and digitizer problems. And that"s a big problem since you"re going to control the device with the touchscreen anyway.

As far as we could remember, phone manufacturers build the touch panel/digitizer with the LCD itself, while the copied screen manufacturer build it separately on the surface glass. Hence, there"s a difference in touch sensitivity. Additionally, copied phone screens usually drop the high touch sampling rate, meaning your screen may not respond to your touches faster.

Here"s also another major issue with the digitizer on copied phone screens. When you crack a copied screen accidentally, the touchscreen stops working, stopping you from accessing the device until you fix it again. Meanwhile, the touch on the original phone screen works perfectly, even after undergoing severe cracking.

Besides having touch problems, most copy phone screens usually have poor display properties. That means you get lower brightness, colour accuracy, sharpness, contrast, etc. And when the display isn"t great, watching movies and viewing other content becomes boring.

For instance, if the original screen is supposed to have 480 nits of brightness, but the copy screen has just 200 nits, the screen becomes unusable under bright lights. Moreso, copied phone screen seems to have more blue light, which, in return, affect your sight and disrupts your sleep at night.

Among others, copied phone screens drop higher refresh rates, and that"s a bummer since most phones come with at least 90Hz refresh rate screens. What that means is the copied screen won’t feel smooth as it’s supposed to be.

It"s not all about the display quality. A copy phone screen may also affect other parts of the phone system if its specifications don"t tally with the original one. In such a case, it could drain your battery at an alarming rate, or at worse, damage your backlight.

If you happen to have a phone with an in-display fingerprint sensor, then replacing its screen with a copied one is not an option – it’s going to mess with your fingerprint accuracy.

We know copied phone screens for their poor quality, and it also extends to the fingerprint sensor. Hence, it takes a longer time to unlock your device. And in other cases, the security of the sensor is not accurate. We"ve seen situations where phones get unlocked with many unregistered fingers after replacing the screen with a copied one.

If you care about your phone"s security and you don"t want a sluggish fingerprint sensor, then we recommend you only go for the original phone screen replacement.

That brings us to the last difference we’re going to mention between copied and original phone screens. They manufacture copied phone screens with poor glass materials. Hence, they break quicker than the originals. And when they do, you’ll be left with only one option: to replace the screen again.

The major reason for choosing the official service centre over third-party/local repair shops summarizes what we"ve said earlier. The official service centre is the reliable place to get original phone screen replacement parts.

Why? As of today, smartphone phone manufacturers/brands release genuine spare parts only to the official service centres and affiliated repair centres. That means third party repair shops get their spare parts somewhere else: usually third-party factories/companies not related to your phones brand.

Besides offering you the original screen spare parts, the official service centres also have other advantages. These include certified and well-experienced technicians to fix the screen, the use of modern tools that won"t damage your phone further, and most importantly, a reliable warranty. Local repair shops usually don"t offer these features; most especially a reliable warranty, which means you"re on your own if the replaced screen gets faulty afterwards.

As far as choosing the official service centre is concerned for genuine screen replacement, then you shouldn"t shy away from Carlcare Service if you own a TECNO, Infinix, or itel phone with a cracked screen.

We"re the official service center for these three brands to cater for your mobile repair needs. And for screen replacement, Carlcare delivers excellently. Our brand-trained technicians replace your cracked screen with genuine OEM parts at affordable rates.

We understand you have a busy schedule; and yes, we"ll replace your screen in the shortest possible time. Start by checking how much it cost to fix your cracked phone screen, then you can book an online reservation service with us to reduce your waiting time and also become a VIP customer.

However, if the digitizer or LCD is also damaged during a fall, that screen no longer carries value because it cannot be refurbished. Repair shops cannot sell broken LCDs to refurbishing companies; therefore, they cannot offset the cost of an LCD repair. That is why repair stores often charge a little extra if there is damage to the LCD or digitizer, to make up for that loss. Repair stores that don’t have an additional charge for an LCD repair typically inflate their glass repair price to make up for the loss from damaged LCDs. If they have one price, that means everyone is paying more to cover the cost of customers who have damaged LCDs and customers who only have cracked glass. This is why TCR separates the price of glass and LCD repairs for you! If you only have cracked glass, you only have to worry about paying to replace the cracked glass.

If your phone or tablet’s glass is shattered there will be cracks or chips on the screen itself. If it is just the glass that is damaged, the device may still function and you may be able to use it normally. If this is the case, it is likely that only the glass needs to be replaced. To prevent further damage to your device it is best to get it repaired quickly. For example, if liquids seep through the cracks it could cause permanent damage to the LCD.

Many people may continue to use their touchscreen with shattered glass and delay fixing the glass on their devices; however, if the touchscreen isn’t responsive, it could be a sign of more significant damage to the device’s digitizer which is integrated with the LCD screen.

A pixelated screen can indicate LCD damage. This would look like a patch of multicolored dots, a line or lines of discoloration, or a screen with rainbow colors. For many people, these colors are an easy way to know that their LCD is broken and that they should get it repaired.

Dropping your phone isn’t the only reason you’ll end up with a pixelated screen. Over time, your screen’s LCD may break down through regular use. This happens to other devices aside from your smartphone or tablet. Pixelation can happen to TVs and computers, too. People typically decide to buy a new device when this happens. Fortunately, with an LCD repair, you can fix the device without needing to replace it.

A black screen or black spots on your smartphone or tablet is an indication of a damaged LCD. Often with a bad LCD, a phone may still turn on and make noises, but there is no clear picture. This does not necessarily mean any other part of the phone is damaged and a simple screen replacement will get it functioning again. Sometimes it can mean a battery or other internal component is damaged. It is best to have a highly qualified phone repair technician diagnose what is wrong so the appropriate repair can be made.

Fortunately, your mobile device is fixable whether you cracked the glass or damaged the LCD. Stop by or call TCR: Triangle Cellular Repair at (919) 263-2699 for a free diagnostic and quick, affordable cell phone repair in Chapel Hill and surrounding areas. We’re always happy to help!

“Original” screens are those containing LCDs manufactured for Apple. “Copy” screens are compatible replacements entirely designed and manufactured by third-party companies not associated with Apple.

LCD display panel can have poorer resolution (i.e. looks “coarser”), worse brightness, contrast and vibrancy and reduced refresh rate amongst other problems.

Changes in specification from original can result in battery and performance issues. Certain badly-engineered screens could even damage the backlight circuitry.

Customers who bring their iPhones to us for a screen repair are offered two choices of replacement- an original or a “copy” screen. The most common response is “Is there a difference- and which one would you recommend?”

Originals are those screens containing LCDs that were manufactured for Apple. So-called “copy” screens are compatible replacements, but designed and manufactured entirely independently by third-party companies, typically in China.

Our answer is simple- the original screen is the one we’d go for ourselves, every time. Some people think we make more money on them, but this isn’t the case. We recommend originals because they’re far higher quality and the price difference is fairly small.

We’d rather only fit original screens. The only reason we don’t is that many people will shop around and choose purely on price. As such, we need to offer the cheaper copy screens to remain competitive and avoid losing these customers. In some cases, they didn’t even know there was a difference in the first place- especially since it’s not in some shops’ interest to draw people’s attention to the issue!

This may well be the worst copy screen we’ve ever come across. As a result, the unfortunate customer has ended up paying twice to have their screen replaced- we’re sure that had they been properly informed, they would have chosen an original in the first place.

While the difference in price between copies and originals can vary across devices, it’s generally around £10 – £14 extra to have an original screen fitted. This really isn’t a lot considering the improved quality and reliability.

We compare our prices to our competitors- and we know that we come out of it favourably. While we have to offer copy screens to remain competitive, we always advise customers to go for the original.

When you’ve spent- directly or indirectly- several hundred pounds for an iPhone with a Retina display, it doesn’t make sense to replace it with a lower-quality screen that can make a £400 phone look like a £40 one! Not only that, but you’re likely to have fewer issues, and a longer-lasting screen.

There’s nothing stopping any random person without training or experience opening up a smartphone repair shop. As a result, the industry is full of companies with little skill or experience who are only interested in getting hold of your money and installing the cheapest parts they can find.

Many- if not most- don’t even acknowledge the existence of copy screens, let alone explain the difference to the customer. Hardly in their interest to do so if they only fit cheap, low-quality copies. Some of them can hardly be blamed- they know so little, they’re not even clear on the differences between OEM, non-OEM and copy displays themselves! Others can be more deliberately misleading… and some outright lie.

Generally, these shops are looking for the cheapest price on replacement screens.. When offered a copy at a half or a third of a price of the original, they’re going to go for that. That might be fine if they offered the customer a cheaper price- what we disagree with is selling “supermarket beans” (i.e. the copy screens) at “Heinz beans” prices!

Heading towards the “blatantly fraudulent”, we’re aware of companies that shamelessly fit copy screens while claiming them to be original. Worse, they’ll take your broken original screen and sell that to a recycler for more than they paid for your copy!

Obtained or manufactured “off the clock” via the same production line that produced them for Apple- in some cases, from the stockpile of parts that didn’t meet Apple’s standards, or

Apple tightened up their supply chain around 2015, which reduced the number of screens available for repairs and increased their price dramatically. A lot of companies went bankrupt, and Chinese manufacturers responded by making their own “copy” screens from scratch. At first, these weren’t much cheaper than the Apple ones, but the price soon fell.

We should be clear that- despite the name- “copy” screens aren’t direct copies of the Apple originals. Rather, they’re compatible replacements that have been designed from scratch and- as a result- vary in some respects that have an effect on usability and quality.

One of the most important differences between an original and a “copy” screen is how the digitizer (touch sensor) is designed. Apple has it manufactured as part of the LCD itself, whereas the copies have it on the glass.

Although there are only a small number of manufacturers of the bare LCDs themselves, these are then bought by countless other companies who add the remaining components needed to turn these into a complete working screen. As a result, you could easily end up with an LCD from the best “copy” manufacturer, but the digitizer/touch (as part of the separately-manufactured glass) from the worst.

There are countless digitizers out there, and you can only take the supplier’s word that the quality is good. Many ship good ones at first, then switch to cheaper parts to make more profit. This is particularly bad with the iPhone 6S and 6S+, since Apple moved the chips responsible for touch processing onto the LCD itself. As a result, you’re not just getting a copy screen- you’re getting copy chips too.

The performance specification (power drain, etc.) of most copy screens isn’t identical to the originals. As a result, they can drain the battery more quickly and mislead the operating system which was optimised for the original screen design.

It’s even possible that this mismatch could damage your backlight. We do a lot of subcontracted repairs for less-experienced shops, and get backlight repairs in almost every day. We’ve had cases where we fixed the circuit, fitted the new copy screen to test it, and had it break the circuit again!

Copy screens can disrupt the touch ID fingerprint reader. With the 6S, 6S+, 7 and 7+, the home button- part of the 3D touch- is part of the screen assembly. Frequently the home button flexes on aftermarket designs don’t work properly and stop the touch ID working- annoying if you use it to unlock the phone or log in to your bank.

We’ve seen many lift away from the frame that holds them in place. This usually results in the flex cable getting torn, and the screen needing replacing. You don’t even need to have dropped the phone- this often happens through general everyday wear and tear.

That brings us to another major issue with the copies. When you drop an Apple original, the glass often breaks, but if the LCD itself is intact, you can continue to use it until it’s fixed. With the copies, the touch/digitizer is on the glass and stops working when that’s broken. Even worse, the LCD itself is more likely to break due to the thinner and more fragile glass.

We’re not convinced this will happen, since Apple recently changed their repair policy to accept iPhones with third-party screens. However, it is possible that copy screens could be stopped from working via an iOS update, since those make a number of security checks.

As often as you use your smartphone, it’s almost inevitable that you’ll eventually drop it. You may be extremely careful, but it only takes one fumble for your phone to tumble. While iPhone screens are designed to withstand impact, you might still end up with a shattered screen.

The good news: a broken screen doesn’t mean your phone is kaput. In fact, if only the glass is broken, the fix is quick and inexpensive. The bad news: if the LCD screen is broken, you’re looking at a pricier repair.

If you’ve looked into replacement parts, you’ve likely come across two very different options: a glass screen, and an LCD screen. While the first option is cheap, the second is definitely not. Here’s the difference:

1. The glass screen is the exterior layer on your phone’s display. While it is specially engineered for durability, it’s still just glass (between layers of plastic film), which is why it’s not very pricey to replace.

Most of the time, the damage to your screen will be pretty obvious. You’ll see the spider web patterns of shattered glass across the front of your iPhone. Occasionally, however, the glass screen will be intact, and you might not realize the damage until you try to use it. Whether the damage is visible or not, it’s a good idea to run a quick diagnostic to determine the extent of it.

If you encounter any of these problems, you’re dealing with a broken LCD screen. If the glass is shattered, but the display is clear and touch capability is working, that’s a good sign. The problem is probably just the glass screen.

Whether you’re dealing with cracked glass or a broken LCD screen, you can find a quick, reliable repair service at FastPhoneRepair.com. Our qualified technicians will get your iPhone repaired and up and running again in record time and at reasonable rates.

Maybe your significant other tossed your phone off the balcony after discovering flirty texts with a certain coworker, or maybe you were just blackout drunk and dropped your phone on the club’s tile washroom floor while taking a shameless mirror selfie. Either way, your mobile’s glass screen likely looks like a drunken spider’s web.

Luckily for you, smartphone repairs in China are both affordable and fast. But before you venture off to your city’s electronics sales and repair market, we encourage you to browse these six helpful tips for repairing your phone screen:

As with damage to just about any electronic product, knowing the extent of the destruction will go a long way towards ensuring your trusty repairman doesn’t try and pull a fast one by over-quoting or overstating the damage.

In the case of phone glass and the LCD – or more recently AMOLED – screen underneath, it helps to know whether just one, or both, of these elements needs replacing (particularly so you can better estimate the cost).

While broken glass on the front of your mobile is obvious and easy to diagnose, a damaged screen (the part that actually displays all the programs and interface) can be a bit trickier to identify. Look for black spots, discolored areas, new lines and out-of-place patterns on your screen, as any of these may indicate a problem with the screen. Naturally, a totally black screen is a pretty good indicator that something is amiss.

One way to test your screen is to hold down on an app on your phone’s ‘desktop area’ until it starts vibrating, allowing you the move the app to new locations on your screen. Move the app to all parts of your display, if the app is unable to reach a certain area, this is a good indication that you’ll be fixing more than just broken glass.

From our experience, this may very likely be the most important step of all. When having your device"s screen or glass fixed, be sure to show the person doing the repair that all of its key components are in working order. In particular, be sure to demonstrate that both your front and rear cameras work, as well as the speaker and microphone.

We cannot count how many times we have heard of a phone being returned after a repair only for the owner to discover that the phone’s microphone (key for, you know, speaking on the phone) or cameras are no longer working. Also from experience: most repair people are unlikely to take your word that your camera was fine before you handed it over to them.

This should probably go without saying, but here we go anyway: having your mobile device repaired by someone other than a company technician from your phone’s particular brand will likely (like basically 100 percent) result in your warranty being voided.

Not every repair shop will give you the option of watching your phone’s crushed glass be replaced. This is because many smaller shops, particularly in electronics markets, will have your phone sent to an offsite repair area and tell you to come back in a few hours to collect it.

If possible, try and find a shop that will complete the repair in front of you. The main reason we encourage this is because we have heard several unfortunate stories where costumers have had their fully-functioning phone battery swapped out for one that can only hold a two-hour charge. Sad!

The price of having your phone’s glass or LCD screen replaced will depend greatly on the make and model of your phone, the honesty of the person fixing it and – like all things in Asia – your bargaining skills. If your local smartphone repair person wants RMB300 to replace your iPhone 6’s shattered glass, lowball them and offer RMB150. From our experience, repair people seem more inclined to budge on price when it comes to older model phones, meaning your brand new iPhone Xs Plus or Huawei P20 will likely have a higher price point and less discount wiggle-room.

Finding a good repair shop with honest staff who do repairs at a high quality and reasonable price can sometimes be difficult. If you manage to track down a good phone-fixing location, be sure to recommend it to your friends to save them the potentially costly and annoying trial-and-error process when having their glass or screen replaced.

I need to replace my cracked digitizer/glass on my OnePlus One and it seems changing only the digitizer is kinda hard so next thing is to get the full LCD to replace.

It seems logical that lcd + frame is easier but it seems it requires to move components/motherboard around which for me seems more prone to mistakes and problems then just buying an LCD and putting it into my old frame.

hi, my phone got into water. i had it dried on hair dryer, rice and silica gel for several days. when i try to turn it on, it vibrates but the screen is black. if i charge it, the only thing that shows is the percentage but remains unresponsive. which part of the screen should i change? thank you

Sir, Last evening Im using FB app and suddenly within a minute my phone screen turns black and everything inside working but black screen remains the same. From last 1.5 years, I didn’t let my mobile fall from hand. Need your assist and advice.

I have a Nokia 6.1 (TA-1045). It’s screen started to come off due to swollen a battery. I followed YouTube videos to use a hair dryer to carefully remove the screen and fix the battery issue. When I reinstalled the screen the lights on the side come on but the screen is black with a small gray area on the left bottom side of the display. Phone turns on and receives calls and appears to be working properly but does not show anything on the screen. I don’t know if I too much heat while trying to remove the screen.

Could it be a problem with the screen, flat cable or main board? Is there anything I could do to test if the LCD has gone bad or entire screen with digitizer has to be replaced?

Thank you. The battery issue is resolved but my Nokia 6.1 display is not working. It has a black screen with a small gray area. I replaced the display with a new one but I still have a black screen (no gray area). My phone turns on and appears to work fine other than no display. The touch screen is also working. Can this be a problem with the main board of the phone or a loose connection?

Did the Phone Fall anytime? There could be 2 Reasons: 1) The connector of the Display is Lose in the Main PCB of the Phone. Remember that the Display and Touchscreen and two different things. The Touchscreen has different Connector to the Main Board. (2) The Display has gone Faulty and needs Replacement.

Get the Phone checked and see if the Display Connector is Fixed Properly. If it is Properly Fixed and the Problem is Still there then maybe you have to Replace the Display.

Your Touchscreen is OK. The Display is Gone Faulty. Replace with Combo Set. Also Install a Protective Gorilla Glass of the Duplicate Combo for Safety as they are very delicate.

You mean you Replaced the Old Display with New One and it is still not working. If yes, then there is serious problem with the Board. It is better to get Rid of such a Phone and Buy a New One.

Sir,mera phone Lenovo K8note hai,screen pahle aadhi hokar,linings aati thi,phir Black Hokar bandh ho rahi thi, maine combo naya lagvay ,par problem solve nahi hua,ab mujhe Kya solution de sakte hai,Kya karna chahiye .

Don’t switch ON the Phone it Shorting May Happen. Disassemble the Phone Completely and Clean with Tinner or IPA Properly. Assemble Back and Check. If the Problem is NOT Solved then Disassemble again and Apply Liquid Flux All Over and Board and Give Heat. Assemble Back and Check. If the Problem is still NOT Solved then the Phone is Short. It must be Checked Properly by some Experienced Technician if you have No Experience.

Sir my micromax unite 2 A106 model while pressing power button to check sms or calls display goes blank only only touch buttons blinks to see display again i have to remove battery and insert it and ON power butpleasedaily it happen for 3-4 times please help me

Display is not appearing in my mobile Nokia Lumia 610. When I was dialling a number, screen blinked and fluctuated and disappeared and now there is no display at all.

suddenly there is a sparking sound in my phone,remove the battery and sim card. After that I inserted sim and battery and ON the mobile, the SAMSUNG logo appears and then SWITCH OFF. Automatic ON and OFF repeats. please tell me about the problem and can i repair this phone?

Replace the battery and check. If the mobile phone gets ON then change the battery. Otherwise, there is problem in the power section of the mobile phone. Take it to Samsung Service Center.

I cracked my screen today. I was at the beach and decided to ride the roller coaster. The ride worker pushed the lap support down and my phone was in the wrong position in my pocket. I have an orzly screen on it and a case but that did not stop the screen from cracking. The crack goes horizontally a...

If you see a red light, your battery is fully discharged. If the red light is flashing, there isn"t enough power to turn on. Charge your phone for at least 30 minutes before restarting.

Crashing, freezing, and restarting are usually signs of a software or app problem. This means your device isn"t broken, but probably needs some cleanup.

Check if the problem only happens at the edge of the screen. This could be normal. Screens often have lower sensitivity there to prevent accidental touches.

Check if this problem happens when using multiple apps or a specific app:If this problem happens with multiple apps, your device may be low on memory. Close all apps but the active one.

Cracked or broken mobile device screens can be costly to fix, but a few inexpensive do-it-yourself strategies can eliminate a repair shop visit and salvage your tablet or phone.

Third-party repair shops typically replace glass on a tablet for about US$100-$200, depending on the model. Replacing the tablet’s touchscreen can cost $50-$75 extra.

Replacing the cracked glass with a functioning touchscreen is much cheaper. You usually can find suppliers online for $6 to $20 for a phone. A tablet replacement digitizer can cost about $50 or more if you perform the work.

It is relatively easy and cheap to replace the glass on a phone once you get the hang of it. Tablets are a bit more involved because of the larger size and added components.

Tools might require an additional monetary outlay if you do not have a well-functioning workbench. Depending on the device involved, you need a phone opener pry tool, little tweezers to deal with small cables inside, a Torx screwdriver, flat-head screwdriver and a precision screwdriver kit.

Add to that list either a variable hair dryer or a heat gun to soften glued phone parts. Also add scissors, double-sided adhesive tape, canned air and work gloves.

It is first things first when it comes to fixing cracks on a smartphone’s screen. Often, the actual screen is not cracked at all. You may have installed a glass screen protector when you purchased the phone.

The film covers can become cloudy or scratched. They usually help absorb shock from items dropping on the tablet to lessen risk of cracking the touchscreen glass under it.

When the culprit really is a damaged screen, choosing one of the next three approaches can help you solve the problem. You might be able to repair the damage rather than replace it.

For instance, is the screen clouded or otherwise damaged from your mistaken use of harsh cleaning fluids or coarse paper towels to clean the screen? If so, there is a fix for that.

Is the screen merely cracked or full-out broken — as in massive spider cracks from being smashed? You can cure a cracked screen on a phone or tablet more easily with Sugru, a commercial product. A fully cracked screen on either type of device is a solid candidate for a screen replacement.

If your phone or tablet screen shows signs of cleaning abuse or wear from heavy handling, return its condition to nearly new with an oleophobic coating kit. This is an oil-repellent coating that protects the screen, along with adding smoothness and reducing fingerprints.

The coating, a thin layer of fluoropolymer-based solids, is similar to Teflon and is bonded to the glass. You can buy the coating kit from a variety of electronic supply stores and online outlets.

Prepare a wiping finger. The oleophobic coating’s liquid solvent evaporates very quickly when applied, so once you start, work quickly. Wrap one finger with plastic wrap or a sandwich bag. Use this finger to rub the coating liquid onto the screen.

Apply 10-15 drops of the coating to the screen’s surface. If the phone or tablet screen has a large surface, apply 10 drops to a portion of the screen, working on one portion at a time.

Wipe the screen dry with a clean microfiber cloth. Then give the coating time to dry. Do not touch the screen for 8-12 hours to allow the coating to bond to the surface.

If your only complaint involves tiny scratches and cracks on a smartphone screen or a tablet glass, there are remedies that work with varying degrees of reliability. You can use a household eraser pad or an actual pencil eraser.

Pencil erasers also work reasonably well in making scratches disappear. Simply rub the scratch left and right with the eraser for about 60 seconds. Then rub it up and down for 60 seconds.

Does using toothpaste to fill in the cracks really work? I put that fix in the category of more “mythful” thinking, but I know people who swear that this method is a cheap fix that works.

Sugru is a moldable glue kit for repairing rather than replacing cracked screens. Actually, the product was not created with phone and tablet repairs in mind. Its intended purpose is more in the line of general repairs where bonding surfaces together and filling surfaces are needed.

Depending on how badly the screen is damaged, it can be a good solution for cracks that spread from the phone or tablet screen’s edges. However, for massive cracks that spread over the entire screen — as spider cracks tend to do over time — it will be a short-term fix at best.

If your phone or tablet screen has suffered more serious damage, full scale surgery is the only option other than getting a new device. Repairing the device’s LCD screen is a complicated procedure due to the compact internal design.

The repair process involves completely dismantling the phone or tablet’s outer casing. It is particularly easy if the replacement screen comes with a top frame.

Otherwise, you may have to seal the layers to avoid loss of structural strength and moisture/dust protection. You can use either sealing pads for the size of the particular device at hand or double-sided sticky tape. A simpler solution for phone screen replacement is to use B-7000/T-7000 glue.

Before you roll up your sleeves to get started, take one huge safety step. Buy and use a static wristband and a static guard mat. This will ensure against accidentally frying any electronic components while disassembling and reassembling the devices. Disconnecting the battery is not always a guarantee that static discharge will not happen.

The first step is to tear down the device so you can assess the extent of the damage and determine what screen parts to order. Locate the model number for the LCD screen. Use this number in an Internet search to find a replacement screen.

The part or model number usually is printed on a label adhered to the sensor cable attached to the screen. You can access this cable after you separate the screen from the rest of the unit. Carefully disconnect the cable connector from the backside of the screen along the edge.

Step 2: Loosen any stuck-on cabling that is now exposed, like the camera cable. Then remove cables if the clasps are exposed. These cables simply slide out of any exposed sockets after clasps are released. The tape-style cables are often held onto the frame and parts by adhesive, so tug gently to release.

Step 3: Unscrew the Phillips or Torx screws that hold the motherboard-containing back frame to the LCD-containing chassis and place the screws in a bowl for safe-keeping. Then separate the back frame from the chassis by gently and carefully pulling the two apart.

Step 4: Remove any further cable assemblies that have become exposed by the separation of parts. Maintain visual cues as to which cable to reattach where. For example, place them on the work surface face-up in the order of removal. Or take photos with a digital camera or smartphone.

Step 5: Remove the LCD-containing chassis from the front frame or bezel and glass assembly by unscrewing a second batch of screws. Store the second set of screws in a second bowl. Remove any further parts such as the camera.

Step 6: Don’t touch the LCD face. Separate the existing, damaged glass from the bezel or front frame by waving the heat gun over the adhesive join and pulling apart. Wear gloves here because the process involves further breaking the glass.

Tip: Be patient while the heat gun loosens the adhesive and be careful not to break the bezel or front frame while removing the glass. You need the bezel intact.

Step 1: Attach fresh two-sided tape to areas of the bezel that have lost their stickiness. Use the existing adhesive where possible. Do not allow tape to overlap the visual part of the glass.

Step 2: Look for any foam padding or seals and reattach. Do not touch the inside of the glass. You won’t be able to get rid of the fingerprints after assembly.

Step 3: Thread the digitizer cable and remount the new digitizer glass to the bezel by firmly pressing it into place. Then remove any dust from the LCD and glass with canned air.

You may have to assemble and disassemble a few times. The two sets of screws use similar holes. It is easy to insert the initial set of screws into the wrong holes. You will realize that only when the second set does not fit because you already used the hole.

Replacing damaged touchscreens and digitizer panels is not rocket science, but the process does require careful attention to details. Following visual guides and screenshots can make the difference between initial success and having to make second or third efforts.

Smartphones are the opium of the people. If you need proof, just watch the average person’s reaction when they break “their precious”. Repairing smartphones has become a huge business. The most often broken item on phones is of course the front glass. In most cases, the screen itself doesn’t break. On newer smartphones, even the touchscreen is safe. The front glass is only a protective lens.

The easiest way to repair a broken front glass is to swap the entire LCD assembly. For an iPhone 6 plus, this will run upwards of $120 USD. However, the glass lens alone is just $10. The problem is that the LCD, digitizer and front glass are a laminated package. Removing them without breaking the wafer thin LCD glass requires great care. The hardest part is breaking down the optical glue securing the glass to the LCD. In the past that has been done with heat. More recently, companies from China have been selling liquid-nitrogen-based machines that cool the assembly. Now immersing a phone screen in -196° C liquid nitrogen would probably destroy the LCD. However, these machines use a temperature controller to keep a surface at -140° C. Just enough to cause the glue to become brittle, but not kill the LCD.

[JerryRigEverything] doesn’t have several thousand dollars for a liquid nitrogen machine, but he does have a $5 block of dry ice. Dry ice runs at -78.5°C. Balmy compared to liquid nitrogen, but still plenty cold. After laying the phone screens down on the ice for a few minutes, [Jerry] was able to chip away the glass. It definitely takes more work than the nitrogen method. Still, if you’re not opening your own phone repair shop, we think this is the way to go.

Broken phones are a cheap and easy way to get high-resolution LCD screens for your projects. The problem is driving them.[Twl] has an awesome project on Hackaday.io for driving phone screens using an FPGA. We haven’t seen it done with iPhone 6 yet though. Anyone up for the challenge?

People with cracked touch screens or similar smartphone maladies have a new headache to consider: the possibility the replacement parts installed by repair shops contain secret hardware that completely hijacks the security of the device.

The concern arises from research that shows how replacement screens—one put into a Huawei Nexus 6P and the other into an LG G Pad 7.0—can be used to surreptitiously log keyboard input and patterns, install malicious apps, and take pictures and e-mail them to the attacker. The booby-trapped screens also exploited operating system vulnerabilities that bypassed key security protections built into the phones. The malicious parts cost less than $10 and could easily be mass-produced. Most chilling of all, to most people, the booby-trapped parts could be indistinguishable from legitimate ones, a trait that could leave many service technicians unaware of the maliciousness. There would be no sign of tampering unless someone with a background in hardware disassembled the repaired phone and inspected it.

The research, in a paper presented this week at the 2017 Usenix Workshop on Offensive Technologies, highlights an often overlooked disparity in smartphone security. The software drivers included in both the iOS and Android operating systems are closely guarded by the device manufacturers, and therefore exist within a "trust boundary." The factory-installed hardware that communicates with the drivers is similarly assumed to be trustworthy, as long as the manufacturer safeguards its supply chain. The security model breaks down as soon as a phone is serviced in a third-party repair shop, where there"s no reliable way to certify replacement parts haven"t been modified. Advertisement

The threat of a malicious peripheral existing inside consumer electronics should not be taken lightly. As this paper shows, attacks by malicious peripherals are feasible, scalable, and invisible to most detection techniques. A well motivated adversary may be fully capable of mounting such attacks in a large scale or against specific targets. System designers should consider replacement components to be outside the phone’s trust boundary, and design their defenses accordingly.

To pull off the attacks, the researchers started with a normal touchscreen and embedded a chip in it that manipulates the communication bus, which transfers data from device hardware to the software drivers included with the OS. This technique simulates a "chip-in-the-middle" attack, in which a malicious integrated circuit sits between two end points and monitors or modifies the communications they exchange.

The malicious chip contains code required to surreptitiously carry out a variety of actions the end user never initiated. The researchers" booby-trapped touchscreen, for instance, logs unlock patterns and keyboard input, takes pictures of the user and sends them to the attacker, replaces user-selected URLs with phishing URLs, and installs apps of the attacker"s choice. A second class of attacks uses the chip to exploit vulnerabilities in the OS kernel. To keep the attack stealthy, the chip can also turn off power to the display panel while the uninitiated actions are performed. (In the following demonstration videos, researchers left the display on, presumably to make it clearer how the attack worked.)

To send malicious commands to the drivers and touch screen, the researchers used an Arduino platform running on an ATmega328 micro-controller module. They also used an STM32L432 micro-controller and believe that most other general-purpose micro-controllers would also work. The researchers used a hot air blower to separate the touch screen controller from the main assembly and, with that, to gain access to the copper pads that connected them. They then connected the chips to the devices using wires that extended out of the phone. With slightly more work, the researchers believe the entire booby-trapped replacement part could be seamlessly hidden inside a reassembled phone. Advertisement

While the researchers used Android phones for their demonstration, there"s no reason similar techniques wouldn"t work against tablets and phones running iOS. The researchers outline a series of low-cost hardware-based countermeasures manufacturers can implement that would protect devices from attacks that rely on malicious screens. The hardware countermeasures would have the added benefit of protecting against attacks that use modified firmware. Another defense might be for replacement parts to undergo some sort of certification process.

In one respect, it"s unsurprising that someone with physical possession of a phone can severely compromise its security with almost no outward sign. Still, the demonstration makes a convincing case that these types of attacks are inexpensive, undetectable, and able to be carried out on a large scale. With one survey suggesting one in five smartphones may have a cracked screen and a plethora of third-party repair shop services that fix those problems, the threat of malicious replacement parts that can"t be detected by the service technicians themselves is worth remembering.
