how to tell if your phone lcd screen is broken factory

Did you drop your phone on the floor? Or did it fall into the water? And now, you observe that the damage is not on the glass touchscreen. Instead, you likely have phone LCD problems. Usually, only the glass screen gets broken, but a significant fall can cause phone LCD problems. If you observe lines, black spots, screen flicker, or discolored areas on your screen, the LCD is damaged. If the screen entirely doesn’t light up, you have Phone LCD problems. Book a phone repair reservation at Carlcare as soon as possible to have your damaged LCD fixed.

You can visit the Carlcare website or app to book an appointment for a repair. Carlcare service centers handle LCD screen replacement not only for Infinix, TECNO, and itel phones. A typical question that most people ask is, how I can repair my LCD screen? The answer is – You cannot fix the LCD. Once the LCD is damaged, you have to replace it with a new one. Replacing the LCD is more technical than merely changing the glass.

The best person to handle the LCD screen repair is a mobile phone technician who has the expertise. So, you may consider taking it to the Carlcare phone repair shop near you.

The cost of an LCD screen repair depends on the phone type and model. Therefore, LCD screen repair for an expensive Android phone will cost more than a cheaper phone model.

Dust is seeping in due to a delay in repairing a damaged screen. If you crack your phone screen and do not fix it immediately, you could damage your LCD. Dust can also seep through the cracks on the screen and cause LCD screen damage.

Water or liquid damage: If you drop your phone into water or some other liquid, some of it could seep into the phone and damage the LCD screen. In this case, you will notice the damage immediately after you turn your phone on.

A fall: The glass and screen protector is supposed to shield your phone LCD from any damage. But, if the phone has a drastic fall, the impact can still cause Android screen display problems. You may notice after the fall that your phone comes on but has a blank screen or lines across the screen.

Poor replacement:If you are experiencing a damaged LCD shortly after changing a cracked phone screen, it could result from poor replacement. Perhaps the technician had used an inferior screen for replacement. As a result, the phone LCD got a problem.

The LCD is present in all phones and some other digital gadgets. LCD is the part of the screen that displays an image in terms of colors. In smartphones, it is the inner screen with all the display features for the phone. Phones usually have another screen or touchscreen protecting and enhancing the LCD screen.

When your phone mistakenly drops, you are usually worried about having an Android display problem. But, there is more cause for alarm if you are having Cell phone LCD problems. The LCD is more important than the outer glass covering it and more expensive to replace. Try to protect the LCD because you cannot manage a damaged LCD screen.

If you also asked, why is my phone glitching? Then you could have LCD screen problems. When the LCD is terrible, it can cause your screen to flicker or shake while using it. A flickering screen is not suitable for the eyes. Your screen might also become unresponsive.

You may sometimes mistake the glass for the LCD of your phone, but they are different. The phone works with a single display which has the glass screen and the LCD components coupled. But, the glass screen is sitting on the top while the LCD screen is inside.

If you have taken your phone for a repair due to the damaged glass, then you should have observed that the glass is different from the LCD even though they are together. Also, the LCD is integrated with the digitizer to allow the touch function to work.

Another difference is the price. If you have damaged the glass, it will cost you less to replace it. LCD is more expensive than glass or touchscreen. If the glass is damaged, you can still use the LCD. But if the LCD is damaged, the glass will not serve you for a more extended period.

The LCD is an integrated component of the phone connected to the digitizer. Since the digitizer converts analog signals to digital signals, some functions may be affected if you have LCD phone problems.

The touchscreen or touchpad:The LCD screen is connected to the device’s digitizer, transmitting touch from the outer glass screen. So, when your phone has LCD screen problems, your touchscreen might also stop responding.

Display: Since the LCD is the display point for the phone, a damaged LCD means that the image display is affected. Depending on the level of damage, you may only see a little, or In extreme cases, a damaged LCD could make it difficult for you to take calls.

Phone LCD problems should not be managed but fixed immediately. If you don’t, it can result in other more damages. Keep the phone away from heat and water too. Also, it would be best if you tried fixing a cracked phone screen as soon as possible.

As soon as you replace your LCD screen, ensure to keep it safe. You can protect your LCD screen by getting a good screen protector. A suitable phone case can also help protect your phone from the impact of any fall.

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!

How do you fix that which is broken? Specifically, how do you access your smartphone—to wipe all of your important data off of it, presumably before shipping it off for repair—when you’ve destroyed the screen?

I apologize for giving away the topic of this week’s Frank is in the spotlight this week:“I have my [Samsung] J7 Pro. How can I wipe or delete all the data on it? The screen and LCD are totally cracked, but it powers on and lights up.”

I’m not quite sure what your broken smartphone actually does, based on your phrasing. If it’s cracked, but it powers up and you can get a reasonable sense of what you’re tapping—if the device even registers your finger-pressing—you can just factory reset it the normal way. Tap on the Settings app; then either “General Management,” “Backup and reset,” or “Privacy,” depending on what it’s called on your Galaxy J7 Pro; and then “Factory Data Reset” to get the process going.

If neither of these solutions work because your screen is too damaged—I dropped my iPhone 4 in a pool once, so I feel your pain—you have two other options.

Once you toggle the factory reset, you’ll need to power on your smartphone in order for it to trigger. And once the factory reset finishes, you shouldn’t be able to locate your smartphone on either Find My Device or Find My Mobile, since it will no longer be associated with your account. (It’s back to its default settings, after all.) That’s a great way to check and make sure the reset worked, in case you can’t see anything on your shattered screen.

Do you have a tech question keeping you up at night? Tired of troubleshooting your Windows or Mac? Looking for advice on apps, browser extensions, or utilities you can use to accomplish a particular task? Let us know! Tell us in the comments below or email.

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.

To find the app that causes issues, uninstall recently downloaded apps one by one. After you remove the app that causes the problem, you can reinstall the other apps you removed.

Slowly drag your finger to the bottom right corner without lifting. Try to move your finger slowly enough that you can count to 10 before reaching the opposite corner of the screen.

IMPORTANT: A factory data reset will remove all data from your phone. While any data stored in your Google Account will be restored, all apps and their associated data will be uninstalled. Before you perform a factory data reset, we recommend backing up your phone.

A broken iPhone screen is no fun. After all, we use our phones for almost everything. If the touch response isn’t working, using your phone can be difficult, and it might not be possible to use it at all. This can make it hard to keep up with friends, plan your day, and even do your job.

There are several reasons your iPhone touchscreen could stop working. One of the most common reasons is physical damage. If your screen stopped working after it hit something, the damage is most likely physical.

Damage from excessive heat is actually quite common. Those who use a car vent clip for their iPhones are likely to experience heat damage if they turn the heat on. Many might not realize that the vent is even on since they don’t feel it, but the iPhone could get damaged in the process.

If your iPhone was exposed to salt water before it stopped working, then that was most likely the cause of the damage. Salt water is corrosive and, while your phone might have been fine right away, the damage could continue to progress for weeks after exposure.

The iPhone actually has two parts to its screen. The top part is the digitizer and the part underneath is the LCD screen. The digitizer is the touchscreen and the LCD screen displays the contents of your iPhone.

When your digitizer isn’t working, your iPhone touch response won’t work properly. Meaning you’ll see your screen, but you won’t be able to interact with it correctly. Sometimes, only part of your screen will work, or it will take extra pressure to tap something.

If your LCD screen is out, your iPhone won’t turn on at all and you won’t see anything on your screen. Alternatively, your screen will be blurry or fuzzy or will have some sort of visible damage.

If there’s a problem with your digitizer, there are a few fixes you can try before taking your iPhone to a repair shop. However, if it’s the LCD, you’ll need to start searching for repairs straight away.

Some users might have activated certain accessibility settings that can interfere with how the touchscreen works. The most common culprit is Touch Accommodations. If enabled, your iPhone screen will seem buggy and you’ll have a difficult time navigating the touchscreen.

Alternatively, you can click the Side button three times and this will disable it on most newer devices. For older devices, you may need to tap the Home button three times.

If turning your iPhone off and on again doesn’t do anything, you’ll need to do a factory reset. Be sure to back up your iPhone before moving forward. If you can use your screen in some way, navigate to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings.

If you can’t navigate here, you’ll need to plug your iPhone into a computer to perform a factory reset. After resetting, in rare cases, your touchscreen will work again.

If you do choose to get your iPhone repaired, you’ll most likely need to do this anyway. This ensures that the technician won’t be able to access your personal data. They may also need to test Face ID to make sure the repair worked and will need the phone to be unlocked to do so, which means you’re better off erasing all your data first.

If your iPhone is under warranty, you’ll want to get Apple to take a look at it as soon as possible. Visit the Apple website to figure out if you have a warranty. If you have AppleCare+, your repair will be deeply discounted.

If you aren’t under warranty and don’t have AppleCare+, you can still use the above link to find authorized repair shops near you. Apple-recognized repair shops are the best place to go to get your device repaired. However, they can be expensive.

If your phone is an older model or you’re on a budget, consider exploring other repair alternatives. Screen repair shops and kiosks are popular, and some of them do a great job for a fraction of the price. However, you might not get the best repair.

You can also attempt the repair yourself, but if you make a mistake you could do more damage. If you want to try it yourself, you can buy iPhone screens online and most of them include a DIY toolkit.

If your iPhone isn’t working but you need to access certain files, you can still do that. To do so, you’ll need to activate Voice Control. This can be helpful for backing up and restoring your iPhone.

To do this, your phone screen will need to at least partially work. If so, try to make your way to Settings > Accessibility > Voice Control and turn that on.

If Siri’s enabled, you can enable Voice Control by saying “Hey Siri, turn on Voice Control.” Once enabled, you can access your iPhone without using the touchscreen.

If your iPhone stopped responding to touch after damage, heat, or salt water exposure, a repair is likely needed. However, a user might have activated Touch Accommodations, which could be the culprit. There are also rare cases where a software problem can cause the touchscreen to work and a factory reset could solve the problem.

No matter what happened to your iPhone screen, it’s important to get your device functional again. After all, we use our phone for everything nowadays, and not being able to use it can change how we engage in daily life.

The methods described above are very effective in allowing access to a device with a broken screen, but to be honest: the second option is a more complicated one, and if you are not familiar with programming commands, you might find yourself completely lost.

Dr.Fone"s toolkit for Android is infinitely more straightforward. To use this program, you only need to connect your phone to your PC and follow simple steps to access your files. However, for Android Control to work, it requires that you have already enabled USB debugging on your device before the accident, so it may not work when you need it most.

Android Control gives you a way to control the device from an external source – you will need to select the files you want to save manually and then copy them to your PC. Conversely, Dr. Fone"s toolkit will allow you to recover all of the files on your device and save them to your PC in just one click.

Dr. Fone"s toolkit is straightforward to use, even if you don’t consider yourself a tech-savvy individual. On the other hand, Android Control requires that you know how to enable USB debugging and learn how to use ADB. This is beyond the capacity of most users, but tech-savvy individuals will likely prefer this method.

As you can see, one of these methods is very easy to use and helps you to claim control over all of your files in less than 5 minutes. The other, Android Control, does require advanced knowledge of ADB. If you have some degree of knowledge and skill in computing, you will likely prefer Android Control. However, if you are not tech-savvy, Dr.Fone - Data Recovery best fits you.

Whichever method you choose to use, we hope you can get all of your files back – a smashed screen can be extremely stressful, and it’s nice to have this weight off your shoulders!

Apple has determined that a small percentage of iPhone 11 displays may stop responding to touch due to an issue with the display module. Affected devices were manufactured between November 2019 and May 2020.

If your iPhone 11 has been exhibiting this issue, please use the serial number checker below to see if your device is eligible for this program. If so, Apple or an Apple Authorized Service Provider will provide service, free of charge.

Choose one of the options below to have your iPhone 11 serviced. Your iPhone will be examined prior to any service to verify that it is eligible for this program.

If your iPhone 11 has any damage which impairs the ability to complete the repair, such as a cracked screen, that issue will need to be resolved prior to the service. In some cases, there may be a cost associated with the additional repair.

What could be worse than having a locked phone with a broken screen? It is truly a nightmare when your broken screen won"t take your touches and you can only get frustrated trying to unlock your phone. Without unlocked your phone, you cannot perform any action such as making emergency calls or replying to important messages.

Well, there is nothing to worry about as you unlock broken screen iPhone and Android smartphone easily. There are several legitimate ways available and we will illustrate every method in detail.

If you have a locked Android smartphone with broken screen, you can unlock your device with an Android control tool. You can remote control your phone from your computer. Besides, you can use ADB and execute certain commands to unlock your phone.

If you want to wipe all data and take it to the nearby service center, you can use Find My Device. Here are all the different ways how to unlock phone with broken screen for Android users.

An Android control tool lets you control your phone from your computer remotely. Therefore, you can easily unlock your phone and perform the required actions on your phone without even touching its screen. We recommend AirDroid Personal as the best Android control tool.

Step 5. Click on "Remote Control" button and you will see the phone screen on your computer. You can unlock your phone and perform any operation you want to.

Android Debug Bridge is more like a command line tool that can be used to establish communication between a computer and a broken screen phone. Using Android Debug Bridge for unlocking Android phone with broken screen is common among advanced users. You will need a computer and Android SDK.

Most importantly, you should have enabled USB debugging option on your phone beforehand for this method to work. Here are the steps on how to access phone with broken screen via ADB.

Step 2: On Command Prompt, type "Cd C:/android/platform-tools". Then type "adb devices" and press Enter key. You will see certain numbers and messages to confirm that your connected device is recognized.

Let us assume that neither have you not installed AirDroid beforehand nor have you enabled USB debugging. You can still unlock your phone with broken screen using USB mouse. This might sound weird but it works like a charm.

Step 4: You can now use the mouse pointer to unlock your phone by clicking on the keys of the on-screen keyboard. You can also unlock pattern lock by drawing the pattern on the screen.

If the above-mentioned methods are not working for you because you could not fulfill prerequisites, you have to use Google Find My Device. Instead of unlocking and accessing phone content in the current state, you can perform a factory reset using Find My Device.

Once you factory reset your locked phone with the broken screen, all the data and setting will be erased and your lock screen will get removed. Your phone will be in the same state as it was when you unboxed the phone. Here are the steps to follow on how to unlock phone with unresponsive screen.

iTunes automatically takes backup of your iPhone. Therefore, when you cannot unlock your iPhone, you can restore your iPhone to any previous version where the screen lock was not present. This will wipe current iPhone data and restore old data based on the time when the backup was taken. You will need a computer and you will need to tap on your iPhone once in the process.

Apple"s Find My iPhone for iPhone users is similar to Google"s Find My Device service for Android users. You can use Find My iPhone service to erase all the data from your iPhone and this will unlock your iPhone. This is because your iPhone will get completely reset and all the settings will return to default.

You can try to trick Siri to unlock your iPhone when you have a broken screen. The steps are slightly complicated and it will take a lot of attempts to unlock your iPhone with the broken screen. Here are the steps to follow.

Step 3: You can use the unbroken part of the screen to move the VoiceOver cursor. VoiceOVer will say which key is not selected. That is how you can type your passcode with some patience and repeated try out.

We have answered your query on "what to do when my screen is cracked and i cant unlock it?" If you have iPhone with broken screen, you should try Sir and VoiceOver method first before moving to erase data option. Unlocking a locked Android smartphone with broken screen is relatively easy. There are several legitimate ways available but AirDroid Personal is the easiest way out as you can remote control your phone screen from your computer.

This diagnostic solution page should help you identify the cause of your broken smartphone screen and find a suitable solution to get your phone back up and running. If you’re having trouble with a black or blank screen on your Galaxy S20, S20 Plus, or S20 Ultra, this is the page for you.

If your screen is displaying images, but is having problems with touch input, try our Samsung Galaxy S20 Touchscreen Unresponsive solution page instead!

It’s possible that your phone screen isn’t displaying any images because the phone is off and the battery is dead. Normally, trying to turn on the phone with a low battery will prompt a display on the screen telling you to charge the phone, but if the battery is sufficiently discharged, the screen may not have enough power to display the prompt.

Try connecting your phone to a charging setup you know is functional for at least 20 minutes.You can test your setup with another USB-C device to ensure it’s providing power.

It’s also possible that your battery can’t charge because your USB-C port isn’t able to transmit power to the battery. If you have a wireless charging setup, you can try charging your phone wirelessly to circumvent the bunk USB-C port, or try gently cleaning out the USB-C port with a toothpick, isopropyl alcohol, and/or compressed air. (Pro Tip: use a dust blower to avoid the harmful environmental impact of spray can dusters.) Once you’ve connected your phone to a power source you know is working, try turning on the phone again.

If your phone still didn’t turn on, there may be a software issue preventing your phone from booting up. Just in case your phone is afflicted, you should perform a force restart while your phone is still connected to the charger:

Temporary files, background processes, and system glitches can cause your Samsung Galaxy S20"s screen to go black and prevent an image from showing. To reset any firmware blips, you can perform a force restart on your phone. To force restart the Galaxy S20:

If the screen is still acting faulty, then you may try backing up your personal data (videos, photos, music files, etc.) and performing a factory reset on your phone. This option will delete all of the files and applications from your phone, starting it back up as if it was new. While this may remedy your problem in a less invasive way than some other options, you should only do so if you are fairly confident that the issue is a software problem. To perform a factory reset on your Galaxy S20:

Lithium Ion batteries like the one found in your Galaxy S20 are only rated for around 400-500 charge cycles before the battery capacity degrades to 80%. For most regular users, this will happen at the 1-1.5 year mark, at which the user will notice that their battery holds less charge and takes longer to reach a full charge. However, at around 50-60% capacity, the battery will start to fail to hold a useful charge and may even struggle with providing adequate power to handle the performance of the phone. If you’ve been using your phone for 2-3+ years and have amassed a thousand or more charge cycles, your phone may have trouble starting the hardware up, even when fully charged.

Additionally, lithium-ion batteries like the one in your Galaxy S20 don’t like to be kept at the extreme ends of their charge range (fully-charged or fully-discharged) for long periods of time. If you’ve kept your phone’s battery at one of these extremes (especially fully discharged) for multiple weeks or months, this may have degraded the battery life significantly, even if your charge cycle count is relatively low.

It’s possible that the screen won’t turn on because of a faulty battery. Although the phone should be able to power on without the battery while connected to a power source, some cases may prevent this from happening.

Case 1: If your battery and USB-C port are both malfunctioning, you won’t be able to turn on the phone because no power is getting to it. You may be able to provide power to the phone wirelessly, but because the battery is incapable of holding a charge, the phone loses power once the phone is lifted up to try to turn it on. To attempt to test this, you can try turning on the phone while it is resting on the wireless charging pad, being careful not to disturb or interrupt the wireless power. However, wireless charging outputs much less power than cable charging, so this may not be enough to power your phone. If your phone does turn on using this method, you’ll want to replace the daughterboard containing the USB-C port, as this will allow you to charge your phone moving forward. You’ll probably want to replace the battery too while you’re at it—Galaxy phones are notoriously glued down, so it’s best not to have to open them twice.

Case 2: If your battery is swelling, the change in volume might dislodge some important componentry within your phone, such as unplugging the display cable. In order to move around components, the battery will likely need to have swollen somewhat significantly, so you can check your phone’s physical appearance for bulging. Be sure to take off any cases before you check, as even the slightest bulge can indicate serious problems with your battery. If your phone is bulging, you should replace your battery immediately. You can use this Samsung Galaxy S20 Battery Replacement guide to do so, but if you haven’t taken apart a phone before, this may be a case to enlist an experienced repair technician. Swollen batteries can present several dangers, such as chemical leakage or combustion, so it’s important to use extreme caution while handling one. Be sure to dispose of your swollen battery properly as well—you can’t throw them in the trash!

If you’ve eliminated discharged/faulty batteries and software issues as a cause for your faulty screen, the most likely culprit is a broken display. The OLED display on the Samsung Galaxy S20 is responsible for generating the images and colors on the screen. It consists of a film of organic compound which generates light when an electric current is passed through it. Unfortunately, this film is subject to damage when it experiences ingress from oxygen or water, so cracks on the screen can potentially cause damage to the display, causing black spots or distortion. If your screen has significant visible damage such as large cracks, or if your phone has been submerged for a substantial amount of time or at great depths, this may be the cause of your display degradation. In any case, you will likely want to replace the display assembly of your Galaxy S20 device. You can do so using one of our screen replacement guides:

Although a rarer case than a broken screen, it’s possible that a faulty motherboard is preventing the entire phone from functioning. Since the motherboard controls all of the processes of the phone, its malfunction would prevent the screen from displaying images or accepting touch input. The most common ways to damage a motherboard (assuming the phone isn’t open) are by allowing water to penetrate the case or by unsuccessfully changing the BIOS settings (usually when attempting to “root” the phone).

Water damage will cause short circuits and corrosion on the motherboard, so if you do open the phone to start replacing components, you can take a look for any spots that look corroded as evidence. If you do see corrosion that looks localized, you might be able to clean it off with some 99% isopropyl alcohol to regain functionality of the phone.

Changes to the BIOS settings can also brick the motherboard, rendering it useless, but will only happen when trying to mess with the underlying operating software—so it’ll be fairly obvious this is the case if you were trying to root when it happened. Unfortunately, bricking the motherboard is oftentimes an irreversible process, so while you might be able to recover it with the help of an expert (why didn’t you have them root your phone in the first place?) it oftentimes means you’ll have to opt for a motherboard replacement.

Green lines are a fairly common problem with smartphones, and they’ve been seen on almost every brand available. When this problem occurs, you’ll typically see:

There are a lot of potential reasons for a green line appearing on a mobile screen. If the green line is accompanied by many other colors, and especially if you can see damage to the glass, the screen itself is probably cracked. If it’s just a single, thin green line that runs from top to bottom, some of the common causes include:

To fix the green line on your phone’s screen, try each of the methods listed below. If the green line doesn’t go away, your phone probably has a loose or damaged display connector, or it may have suffered fall or water damage. In that case, the best solution is to contact the manufacturer or a qualified Android repair technician.

Restart your phone. Start by turning your phone off, and then turning it back on. Don"t just turn off the screen, make sure to actually turn off the phone and restart it.

This basic fix takes care of a lot of problems because it forces your phone to close everything down and start fresh. If the green line was caused by a temporary glitch in your phone’s software, restarting the phone will fix the problem.

Restart your phone in Safe Mode. Safe Mode is a limited mode that prevents anything from launching on your phone aside from the essentials. This is a good way to see if you have a software problem. If the green line goes away in Safe Mode, then you know you have a problem with an app, a setting, or the operating system.

Remove recent apps. If you’ve installed any apps recently, try uninstalling them. If the green line is caused by an incompatible or malfunctioning app, removing it may fix your problem. If you’ve made any settings changes recently, try undoing those changes as well.

Update your phone. Check to see if your phone has any operating system updates available. If there’s a problem with your current version of Android, the update may fix your problem.

Factory reset your phone. This is the last fix you should attempt before you send your phone in for repairs. It’s a drastic option, because it deletes all of the data on your phone, including photos, videos, and everything else, and installs a fresh version of Android.

If the green line is caused by a software issue, the factory reset will fix the problem. If the green line remains, that means you’re dealing with a hardware failure.

Contact the manufacturer for further assistance. If your phone is still under warranty, the manufacturer may repair or replace the phone for free. If it isn’t, they’ll be able to provide you with information on how to have the phone repaired.

If you"re experiencing voice echoing on an Android, try turning off the device, waiting five minutes, and then turning it back on. If it"s still echoing, turn the volume down and see if this helps. Check settings to see if your device has a built-in echo cancellation feature; enable it if so.
