lcd touch screen dead spot factory

A few days ago the lower part of my device"s touchscreen went dead. Whenever I touched the bottom 2 to 3 centimetres of my screen, it simply wouldn"t respond, meaning that the spacebar and a few of the letters on the keyboard didn"t work, along with the buttons in some apps. So I did some research on Google, tried a few solutions ranging from performing a soft reset to taking the phone apart and making sure all the parts were connected correctly, but no luck. A few hours later, my phone ran out of battery and when I restarted it the problem had gone, only to return about 15 minutes later. Therefore, I"m pretty convinced that the problem is software rather than hardware based and am reluctant to perform a hard reset or to replace the digitiser. What should I do instead?

Dead zones on phone and tablet screens are one of the rarest and irritating issues you can come across on your device. If you’re unable to use your device as usual because of its unresponsive touch screens, there are a handful of fixes you can try at home to resolve the problem. This article sheds light on various solutions on how to fix dead zones on phone & tablet screens.

Whether it’s the middle of the touch screen not working, the right side of the touch screen not working, or anywhere not working on the screen, this article will help you fix it. You might not need to visit a repair center too.

Before looking for how to fix dead zones on a phone screen, there are a few things to note. What causes unresponsive touch screens most times is because the screen is cracked. Broken screens may cause some parts of your display to malfunction, especially when exposed to moisture, water drops, and others. If that’s the case, we recommend you go for a screen replacement instead.

More so, if you have a screen protector on your phone, simply take it off. Sometimes, probably because of poor fixing, your screen protector may cause dead pixels on a phone. If you"re wearing a glove or anything is covering your fingers, kindly remove them.

As simple as it is, restarting your phone can fix the dead zones on screens, as well as other issues. And that’s a quick way to diagnose if it’s a hardware problem or some software glitches hanging around the corner.

The next thing to do when experiencing ghost touch or unresponsive touch on your device is to test the part of the screen that is affected. This is surely a way to get to the root of the problem.

While some people experience the middle of the touch screen not working, some might be the right side of the touch screen not working. In that case, you need to check what part of your screen is not functioning.

To do that, we’ve chosen a simple app called Touchscreen Test.You can install it from the Play Store or get its equivalent for your iPhone on the App Store, then follow the steps below.

Ghost touch, dead pixels, and unresponsive touch screens are not always hardware problems on mobile devices. Sometimes, it may be because of an app you installed earlier - a poorly coded or malware-ridden app.

To ensure that what caused unresponsive touch screen on your device is not an app, you need to boot into Safe Mode. In this mode, your phone only loads the system apps. Other apps are paused/disabled until you exit Safe Mode.

Similarly, if you’ve turned on Developer Settings on your phone, you may need to turn it off to fix the dead pixels on the screen – at least on a software level.

Another method of fixing an unresponsive touch screen on your phone is to power it off and remove all the peripherals connected to it – your SIM cards, micro SD card, earphones, and others.

Though rare, your SIM and SD card may go haywire and tamper with some functions on your phone. And most times, the issues seem to disappear after pulling out the SIM card and SD card. So you can try it to fix dead pixels on your screen.

If you experience ghost touch (the screen pressing itself), or an unresponsive touch screen only while charging your phone, the culprit might be that charger you’re using.

The first thing to do in that case is to remove the charger. If the screen behaves normally after removing it, then you might need to get a new charger, or better still, change the cable. Also, if the charger amperage is more powerful than what your phone can occupy, it can affect the screen.

If none of the methods above could fix the dead pixels on your phone screen, you might want to try a more technical solution at home. This method requires you to use an igniter – usually found inside an electronic lighter at home – to create static electricity and fix the dead pixels on your screen.

Warning:though this method has a high chance of fixing dead spots on touch screens, it will void your warranty, and it can damage your display irreversibly. Also, it’s just a temporary fix most times - dead zones may reappear after a few hours, days, or months. So, try at your own risk. Meanwhile, you"re better off visiting a repair center.

As we said earlier, this method will void your warranty and may incurably damage your screen. So, try it at your own risk. And if it worked for you, you may need to keep the igniter at reach in case your dead spots reappear. This method will also fix ghost touch on your screen if you have it.

The last resort if none of the above fixes work, or if you don"t want to lose your warranty to an igniter, is to look for how to repair the touch screen of a mobile phone.

You need to visit a repair center to fix the dead zones on your screen. We recommend you visit the official repair center if your brand has one. They will help you diagnose and fix the problem in a short time. Also, if you need to replace your screen, they will help you out.

Meanwhile, if you’re TECNO, Infinix, or itel device is still under warranty and you don’t have a broken screen, we’ll fix the dead zones on your screen for free!

If your screen is getting unresponsive in some specific places don"t worry too much, you are not alone. It"s a known issue that has been affecting different devices, brands and Android versions. The usual "dead" spots are placed on the four corners, the middle of the screen or some letters when you open the keyboard. Thanks to the community feedback there are some simple fixes that, most likely, will solve your problem. Check them out and tell us if they did the trick for you. Please, feedback is the key

- Clean Master. There"s an special feature called "iswipe" that has been causing different screen problems for some users. Disable or, even better, uninstall this app. It"s possible that you"ll need to uncheck it first in settings - security - device administrators.

- There are a few reports about Samsung Pay or Droid Optimizer causing screen issues that stopped after disabling any of these apps. There"s not much feedback about these apps though, but still worth a try.

Safe mode. This process will temporarily disable every app that didn"t come preinstalled in your phone. If the problem doesn"t appear while your phone is running in safe mode then it means that you have a tedious task ahead. Reboot your phone to exit safe mode and start disabling, one by one, your apps until you find the culprit. You should start with apps that you downloaded or updated right before the problem started and any app with fancy screen features like bubbles, swipe or lock options. Just be aware that some of the apps listed before do come preinstalled in some phones/brands, so they will run even in safe mode!

Developer options. If you"re still reading this there"s a big chance that nothing worked for you and maybe your phone has a hardware problem. There"s an easy way to get visual feedback every time you touch the screen so you can check if there are any real dead spots. You need to have the developer options enabled so if they are still disabled go to settings - about phone - scroll down and tap 7 times on the Build number until they open.

Now, tap & swipe over those places where you are having issues. If you don"t get a visual feedback (broken line when swiping) or the coordinates don"t change, there"s a big chance that you need to visit a repair shop or make use of the warranty. You can see in the screenshot how these options work

Well, I would like to tell you that the touch screen not working or unresponsive touchscreen on Android is a common issue. And, this issue doesn’t only happen with Android, Apple users also experience the iPhone/iPad touchscreen not working issue.

So, if you have also come across the same issue and want to fix it then this blog is definitely for you. Here you will get to know about how to fix the touchscreen problem on Android?

Well, these are not the only ways to deal with this issue. To find out the complete list of solutions, keep reading this guide.

If your Android device touch screen is not physically damaged or smashed and it had stopped working all of a sudden and does not respond to your touch, then this may be caused due to software issues.

If your phone’s touch screen is not working, then it is possible that this issue is appearing due to the system issue. In this situation, it is better to use the Android Repair Tool.

This tool will fix all of the system issues that might be causing this problem on your phone. Not just this, but it can also fix several other problems, such as the phone being stuck in the boot loop, apps crashing issues, black screen of death error, battery issues, and many more.

A soft resetting of the phone is a very basic move but in some cases, it works magically. If the phone touch screen not working is not happening due to any major issue, this trick may get your job done. Here’s how to fix unresponsive touch screen on Android:

Sometimes, the screen damage is not the actual reason for the unresponsiveness. There might be some issue with the memory card or SIM card. In this situation, you should try removing the SD or SIM card from your phone:

Mostly Android touch screen doesn’t work due to the screen protector. Even though a screen protector protects your phone’s screen from damage, dust, scratches, and water drops, it can also cause issues, such as the touchscreen not working.

If there is any scratch on the screen protector or is completely damaged, then thetouchscreen of your phone won’t respond. In this case, the best solution would be to remove the protector.

However, it will only work if the issue is happening due to the screen protector. If it is not working, then there must be some other issue with your phone screen. Hence, follow the other listed solutions.

It is a temporary solution to this issue, but you can use it until you find the actual reason or fix the issue permanently. You don’t only need to rely on the touch screen to control the phone. There are other options too to navigate through the phone.

You can try the 3-party apps to use the face or voice recognition feature to access your phone. However, this trick can only work if your phone touchscreen is at least partially working so that you can download the app.

To control the phone with the voice, you can use Google’s Voice Access app. This app will listen to your commands & assign a number for each action available on the phone screen. After this, you don’t need to tap on the screen.

Now, just call out the assigned number.Voice Access app also fixes the phrases for certain actions. For example, if you say go back, the app will take you back to the previous screen.

The EVA Facial Mouse app is a virtual cursor that can let you navigate through your phone using face recognition technology. To move the phone screen, simply move your phone in that direction.

If the above-given solutions failed for you, then you can try to boot your phone into Safe Mode to fix the problem. It will help you to recognize whether the touchscreen issue is caused due to any of the recently installed apps.

If your Android touchscreen works properly afterbooting the device into the Safe Mode, then it means the recent third-party app was a culprit behind this problem. Once you find out about the troublesome 3rd party app, simply uninstall it on your phone.

If your touch screen problem is not affecting your ability to download apps from the Play Store, then download and install an anti-malware application and scan your device. Maybe this can fix all your problems.

There are various apps available in the Play Store that can calibrate your device’s touch screen and improve its accuracy and responsiveness. These apps are very much effective particularly when your touch screen responds inaccurately or responds too slow.

Open Play Store, type “touch screen calibration” in the search bar and you will get a few results. Check the ratings and read the review carefully before you download them.

Wondering why my phone touchscreen is not working? If so, you should try 3rd party apps tofix display issues on your Android phone. There are so many apps on the Google Play Store that can diagnose the touchscreen problem of your phone.

These apps will help you to pinpoint what is wrong with your phone screen.For this, I recommend using the Display Tester. First, download and install the app on your device and then follow these instructions:

Here, you will get a bunch of options to test the issue from all aspects. With this tool, you can detectburn-in on OLED screens, dead pixels, the accuracy of saturation and contrast, multi-touch status, etc.

If the touch screen is totally unresponsive on an Android phone/tablet, then it is time to perform factory on the device. As doing this will erase all data on your Android device, you should only go with this option if nothing else is working out for you.

If your Android phone or tablet screen has been physically damaged due to several reasons such as a dropped the device in water, on the floor from a high distance, smashing the screen, or breaking the device then the touch screen could be damaged and thus stop responding.

The first thing we are going to do is use the star codes to check if the touchscreen of the Android phone or tablet is working or not. First, dial the start codes compatible with your Android device.

Simply dial the codes, to open the device’s diagnostic mode. Once you enter into diagnostic mode, you can test the touchscreen for bugs and dead zones.

In this case, you can try one trick. Simply, knock each corner of the touch screen 2-3 times and then see if the Android unresponsive touchscreen issue has been resolved or not. If it is still not working, then you can try the next fixes.

There are some instances where the Android touch screen stopped responding after the phone is dropped into the water or due to some reason water drops gets inside the screen.

Nevertheless, you can still fix this problem and get your phone screen back to its normal working condition. For this, you must check out the guide on how to how to fix unresponsive touch screen on Android damaged by water.

There are some cases, where the phone touchscreen can be accessed partially. In this situation, the 3rd party apps can help you out in resolving the problem and enhancing the screen latency. There are so many apps that can calibrate the phone screen to decrease the response time.

This tool will suggest you click on several sections of the touchscreen. After doing this, the app will reduce the latency according to the phone model.

Many people ask how to fix unresponsive touch screen Android but before that, is important to know what are the reasons for the touch screen not working on Android, right?

Physical damage– Maybe your Android phone is damaged or broken. Or maybe it’s due to moisture detected issues, high temperature, static electricity, cold, etc can lead to touch screen damage on Android phones.

The Android touch screen is not working/became unresponsive? Now, wondering how to recover data from an unresponsive touch screen of an Android phone?

You can use the user guide to find out how Android Data Recovery Toolworks in order to recover data from an Android device with an unresponsive touch screen.

Yes, the cracked screen affects the responsiveness of the touchscreen. When the phone screen gets cracked, the digitizer, an important component of the phone, starts interrupting the touch of the screen. But when the phone screen totally get damaged, the digitizer gets exposed to water, dust, moisturewhich leads to major damage.

If you see a phone’s screen then it has two major parts: the actual LCD and the glass. The glass of the screen can be replaced easily but when the LCD gets damaged the repairing of the device becomes a risky task.

There are ways to fix the cracked screen temporarily. You can use a screen protector or tape to fix it. First, clean the phone screen as much you can and put packaging tape over the screen. If there is some extra tape then remove it. And now you can use the phone as before but remember, it’s a temporary fix.

Though the most Android phone touchscreen issue can be solved by removing the screen protector and cleaning the screen with a soft, slightly damp, lint-free cloth. but if that doesn’t work, you can try the other ways shared in this blog to solve how to fix unresponsive touch screen Android phone issue.

On the other, you may also lose your important and valuable data from your device, hence it is recommended that you must try Android Data Recovery Softwareto recover data from an Android device whose touch screen is not working or became unresponsive.

You probably touch your phone"s screen hundreds of times per day. Combined with its delicate glass build, it"s no surprise that smartphone touchscreens are one of the most common components to run into issues.

But the touch screen not working on your Android phone isn"t always the result of a hardware failure. If your phone touchscreen often isn"t working or fails to respond, there"s a lot you can do before getting professional help.

First, you should rule out the possibility of a software bug if your phone touch screen is not working. There are a handful of troubleshooting steps you can do to confirm this.

A good-old reboot might sound futile to fix such an advanced issue. However, it"s often one of the most successful ways to fix an unresponsive touch screen on Android. Restarting your phone shuts down and refreshes all background services, which could have crashed and led to your issue.

If you"re unable to touch the screen to select the option, on most devices, you can hold down the Power button for several seconds to switch off your phone. In some cases, you may need to hold down the Power button and the Volume Up button at the same time.

If your touch screen is not working, but only intermittently, then you may be able to re-boot your phone into safe mode. Android"s safe mode lets you use your phone with only the original software it shipped with, which strips out all services and apps you"ve installed. If your display works normally in safe mode, a third-party app is likely at fault here.

To enter safe mode on most new Android devices, press and hold the power button. In the resulting prompt, touch and hold the Power off button. Once you see the prompt to enter safe mode, tap OK, and your phone will soon restart. To exit safe mode, just restart your phone normally.

If you"re scratching your head wondering, "Why is my phone touchscreen not working?", you"ll find a range of apps on the Play Store that could help you to diagnose your display issues. These are designed to pinpoint what exactly is wrong with your phone"s touchscreen. We recommend trying out one simply called Display Tester.

When you launch Display Tester, head into its Tests tab. Here, you have the option to test a whole bunch of aspects. The app can detect dead pixels, burn-in on OLED screens, whether the contrast and saturation are accurate, multi-touch status, and more.

If you got positive results in touch-based tests, you should review all recently installed apps or consider performing a factory reset. Since your touchscreen functioned as intended under special circumstances, a third-party app is most likely the root cause.

Many people apply a screen protector on their phones as an added safety against drops and scratches. But that same sheet of plastic or glass could prevent your touch signals from reaching the display panel.

If your phone"s screen has been acting up lately, try removing the protector. Of course, this doesn"t guarantee a fix. However, it could increase the response rate on an already weak screen.

Touchscreen Repair is a lightweight app that calibrates your screen to reduce response times. The app asks you to consecutively tap several sections of the touchscreen. Based on your phone"s internals, it then artificially drops the latency as much as possible.

The effectiveness of Touchscreen Repair varies depending on your phone maker. Many OEMs ship their phones with optimal response rates. In those scenarios, Touchscreen Repair won"t be able to do much. But it"s worth a try if nothing else has worked yet.

You don"t have to rely on touch inputs to control your phone. To better serve users with accessibility needs, voice and facial-based interaction methods for Android have come a long way.

With the right apps, you can navigate on your phone entirely through your voice and facial movements. Of course, these solutions only apply if your phone"s touchscreen works enough to install an app from the Play Store.

Else, you can try installing the app to your phone through the Play Store web interface. And you can disable touchscreen input on your phone until you get the screen fixed.

Google"s Voice Access app proactively listens for your commands and assigns a number to every action available on the screen. Instead of touching an app icon or menu element, you just have to call out the assigned digit.

Voice Access links fundamental actions to fixed phrases. So you can say "screen down" for moving around pages and "go back" to return to the previous screen, for example.

This app does exactly what its name suggests. It adds a virtual cursor on your screen, which you can manipulate with your face. To move the pointer, you simply have to move your head in the appropriate direction.

If you can"t install any apps due to screen problems, connecting an external keyboard and mouse might do the trick. This assumes you can still see the screen, though.

With these possible fixes, you should hopefully be able to revive your phone"s touchscreen if it"s just a software bug. Failing that, the apps mentioned can grant you a temporary workaround.

Otherwise, you will have to visit a service center for help. If you"re lucky, a professional will be able to restore the touchscreen"s functions, although depending on the device, it may be a pricey repair. If not, you"ll have to look at replacing your phone.

Your Android touch screen might not be working for various reasons. Hopefully, one of the fixes above helped solve your touch screen issues. If everything fails, perhaps it"s time to upgrade.

Touch screens are great when they work, but when a touch screen stops working, all that ease of use goes out the window and frustration sets in very quickly. The biggest problem is that with some devices, the touch screen is the only way you have of interacting with your phone or tablet. When that suddenly goes away, it can feel like you’re totally locked out of your device altogether.

While there are cases where an unresponsive touch screen calls for professional repairs, there are a number of steps, from easy to advanced, that you can take to get things working again.

Restart the device. It may sound pretty basic, but when your touch screen stops working, simply restarting your touch screen device is usually all it takes to fix the problem.

Clean the touch screen and screen protector. In some cases, a touch screen will stop responding properly due to built up dirt and grime or problems with the case or screen protector. Since this is pretty easy to either deal with or rule out, it’s a good idea to give your device a thorough cleaning if a reboot didn’t do the trick.

Clean your hands to avoid passing dirt onto the screen. Wipe the touch screen with a lint-free cloth. The cloth may be dry or wet, but never use a sopping wet one.

Another slightly more complicated fix for a touch screen is to simply turn the device off and remove all of the sim cards, memory cards and peripherals. The reason this can be complex is that these cards are sometimes difficult to remove, and you have to put them back in one at a time to figure out which one was the problem.

Dry off your smartphone. Touch screens can also stop working, become unresponsive, or work erratically if a phone gets wet. In that case, drying the phone out thoroughly sometimes fixes the problem. There are several steps to drying out an Android and drying out an iOS device.

Gently tap each corner of the phone.When a touch screen stops working after a phone is dropped it’s sometimes due to the digitizer connection coming loose internally. In that case, gently tapping on each corner of the phone may cause it to reconnect.

Remove the SIM card, memory cards, and peripherals.While it is less common, problems with SIM cards, memory cards, and peripherals (such as USB devices) can sometimes cause touch screen problems in mobile and Windows devices. Be sure to fully power down and unplug your device first.

Since touch screen problems can also be caused by files or programs that you download, the next step is to start up your phone, tablet or laptop in safe mode. This is basically just a bare bones mode that doesn"t load extra programs, but it can be pretty complicated to get it going.

Turn on Safe Mode for Android or Windows safe mode. In some cases, a problem with an app or program that you have downloaded can cause the touch screen to become unresponsive. The key to figuring this out is to restart in safe mode, since these apps and programs don’t load in safe mode.

If you find that the touch screen starts working when you enter safe mode, then there is a problem with some app or program that you downloaded. Start with recently downloaded apps and go from there.

Adjust iPhone 3D Touch sensitivity. If you’re experiencing an unresponsive or inaccurate touch screen on your iPhone 6s or later, it may be a 3D Touch sensitivity issue. In that case, assuming the touch screen works at all, you’ll need to adjust that setting.

Go to Settings > Accessibility > Touch > 3D & Haptic Touch.Adjust the slider between light and firm. Try turning off 3D Touch if the screen is still inaccurate or unresponsive.

Calibrate your Windows touch screen. The Windows Touch Screen Calibration Tool helps to reset the center of each touch you make on your device. If you find that your touches seem to be a little off, this might help put everything right again.

If you have a Windows device with a malfunctioning touch screen, then updating the driver might fix the problem. Disabling and re-enabling the driver or reinstalling it might also do the trick.

If your touch screen still doesn’t work after following all of these steps, then it will probably require professional repairs. If those don"t work, it"s time for a new phone.

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.

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 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.

The app does what it says it does: it reduces touchscreen lag and adjusts sensitivity. My phone was having issues detecting my taps, either by lagging or by not registering my tap. After using this app, all of the touchscreen-related issues were resolved! Just one issue: there"s ads on this app, one even covering the screen, and considering how infrequently one would use this app, putting in ads just seems like a waste of effort. Regardless, it does what it"s supposed to, and that"s great!

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.

Under your Pixel 5 phone’s screen, at the top center, you can see a white dot. This white dot is your proximity sensor. When your proximity sensor is on, the dot shows through the display. The dot can blink or stay solid.

Your proximity sensor keeps your phone’s screen off while you hold your phone near your face during a call, when your screen is locked, and when used by certain apps. Keeping the screen off helps save battery and avoid accidental taps on the screen.

All Pixel phones have proximity sensors. Because the Pixel 5’s display goes almost to the edge, you can see the Pixel 5’s sensor under the screen. Check our Pixel 5 phone diagram.

Does your Samsung phone have a frozen touchscreen? Has your iPhone X touchscreen stopped working? Touchscreens are fantastic, except when suddenly they’re not: unresponsive touchscreens are more common than you might think. To say that an unresponsive touchscreen or a touchscreen that is not responding properly is a very frustrating experience would be an understatement!

Android and iPhone users encounter this issue every day. While this inconvenience could indicate that it’s time for a new device, there are also a few simple fixes you can try when an iPhone touchscreen is glitching or when a Samsung display touch is not working. If your cell phone or tablet screen is taking on a life of its own, you’ll need to find the root cause and decide on a suitable solution.

A smartphone touchscreen can become unresponsive for several reasons. For example, a brief hiccup in your phone’s system could render it unresponsive; a screen may also become unresponsive after incurring water damage. Other factors may include debris, app glitches and viruses.

In the absence of these issues, there’s a possibility the screen could be damaged because of an accident. This situation may call for repairs or replacements. That said, you can save time and energy by trying a few quick do-it-yourself fixes first.

Users of iPhones or iPads may find that their screens suddenly freeze. Perhaps your iPad won’t recognize touch and does not rotate when you turn the device. Maybe your iPhone 6 screen is moving by itself, or your iPhone screen stops working sometimes. It’s often confusing to know what to do when your iPhone touchscreen is not working. You tap it or swipe it, and it does nothing in return. Ugh!

Don’t throw in the towel just yet. Determining how to fix touchscreens that aren’t working on iPhone or iPads may be as easy as performing some simple tweaks. The easiest solution to stop your phone screen from glitching (as well as to stop an iPhone screen that’s moving without touching or to remedy an iPad touchscreen not working intermittently) is to shut the phone off and restart it.

There are other considerations and tips to perform when an iPad or an iPhone won’t respond to your touch. Based on your iPhone’s model, a lack of responsiveness may come down to:

Touch Disease: Users of the iPhone 6 and 6 Plus noticed a flickering section toward the top of the screen and subsequently found the device wouldn’t respond.

However, the issue could also be software based. The phone touchscreen may no longer respond when the device needs a firmware update or when too many apps consume its memory.

A non-working touchscreen can be an urgent issue if you rely on your device every day; an Android phone or tablet not responding or an Android touchscreen that’s not working can really cause issues. An iPhone screen that does not respond to touch (or doesn’t respond at all) can be worrisome, especially since it seems like our lives are all on these devices.

These tips will teach you how to fix an unresponsive iPhone screen or Android screen without having to pay for repairs. Try out these methods on your phone first:

Reboot the phone: You can fix an iPhone with an unresponsive touchscreen by rebooting the device. If you’re unable to shut down the phone normally, press “Volume Up,” “Volume Down,” and then hold the side button until the logo appears. You can restart and Android phone without a touchscreen by holding the power button for 30 seconds.

Make sure your device and hands are clean: Moisture, debris and oils on your hands or device can impact its screen performance. We recommend washing and drying your hands and then wiping down the device with a soft cloth before trying the device again.

Check the screen protector: Even if the screen itself is clean, the protector on top may be the issue. Ensure that it’s correctly applied to the surface or consider taking off the case to reapply it. Once you take off the protector, you can test the touchscreen to see how well it responds. Should it become responsive at this point, you may want to consider a thinner protector.

Update your device: Older versions of software often come with bugs that updates are designed to fix. Ensuring that your Android or iPhone device is up to date may improve screen performance issues, particularly if it is unresponsive to touch. You can find available software updates by visiting your device’s “Settings” app.

Use Safe Mode: If you’re looking for a way to fix your Android screen that’s unresponsive, try running it in Safe Mode. This feature disables third-party apps to help you troubleshoot issues. The latest iPhone also offers a Safe Mode feature so you can identify apps that may be untrustworthy.

Do a hard factory reset: In extreme cases, you can fix an unresponsive iPhone or Android screen by returning the phone to the phone or tablet’s factory settings. This will wipe all your data and personal content from the device, though, so make sure you have everything backed up first if possible.

If all the above methods prove ineffective and you’re still experiencing iPhone lost touchscreen sensitivity or a touchscreen that’s not working on your Samsung device, you might have a bigger hardware issue to address. In this case, you can either pay for a repair or sell your broken phone to buy a newer model. At The Whiz Cells, we offer great cash values for your old devices. While broken phones are worth less than fully functional ones, we’ll be glad to accept your device to put some extra cash in your pocket to pay for that much-needed upgrade.

We must verify whether the problem is the display screen of the laptop, video card (GPU), or video settings on the computer. A straightforward way to identify this is to connect the laptop to an external monitor or TV.

If the issue persists on the external monitor, it may be an issue with the video card (GPU) or video settings and not the laptop LCD panel. Go to verify display or video issues in Windows Safe Mode. Otherwise, go to the next step.

Performance issues may occur if there is any damage to the LCD screen. The display may stop working, work intermittently, flicker, display horizontal or vertical lines, and so on, if there is damage to the display screen.

Dell laptops have integrated diagnostic tools that can determine if the screen abnormality is an inherent problem with the LCD screen of the Dell laptop or with the video card (GPU) and computer settings.

When you notice screen abnormalities like flickering, distortion, clarity issues, fuzzy or blurry images, horizontal or vertical lines, color fade, running a diagnostic test on the LCD helps identify if the issue is with the LCD panel.

Press and hold the D key and turn on the computer to enter the LCD built-in self-test (BIST) mode. Continue to hold the D key until you see the entire screen change colors.

If you do not detect any screen abnormalities in the integrated self-test mode, the LCD panel of the laptop is functioning properly. Go to the Update the video card (GPU) driver, monitor driver, and BIOS section.

If you notice any abnormalities in the LCD built-in self-test mode, contact Dell Technical Support to learn more about repair options that are available in your region.

Display settings like brightness, refresh rate, resolution, and power management may affect the performance of the LCD screen on your Dell laptop. Changing or adjusting the display settings can help resolve several types of video issues.

If you find that the Dell laptop is unresponsive to touch, touch stops working entirely, or other touch-related issues, you can try some common troubleshooting steps to help fix the touch-related issue.

If the diagnostic tests on the LCD panel and the video card (GPU) passed, it is most definitely an issue that is related to software that is installed on the computer. If the above troubleshooting steps did not resolve the issue, you may try to restore the computer to factory default settings as a last resort.
