Samsung S20 Ultra, S20 Unresponsive Touch Screen

Let the Phone Cool Off

Overheating issues often happen with phones like Galaxy S20, while playing heavy games like COD or PUBG and also when using the phone for a long time. This later results in disparate problems like the one you are facing currently, Galaxy S20 Touch Screen Not Working.

If you’ve used the phone for a long time, make sure to let it cool. Constant use of the phone can damage internal parts and also the battery. The simple solution is to place the phone in room temperature and uncover it, take off the case.

Clean the Display

If you feel like the display is fuzzy, didn’t clean it for a long time, it may result in touch screen problems on the Samsung phone. To avoid this possibility, always clean the phone once a day to enjoy the greatest display without such irritating problems. Plus, wash your hands before using the phone, this would be helpful.

For the most part, the touch screen will start working, if it is not affected by a software bug or hardware damage. Move on to the next troubleshoot if still, the Samsung S20Ultra touch screen is unresponsive.

Force Restart Phone

To overcome minor software bug, the very first step should be taken is force restarting the phone. However, most of the users already performed a hard reboot as it turns out the easiest and recommended solution to each and every issue.

  • Press and hold the Power and Volume Down button until the Maintenance Boot Display appears, it may take roughly 10 seconds.
  • Choose Normal Boot.
  • It will take approx. 90 seconds to complete the process and boot the phone.

Turn Off Accidental Touch Protection

It appears Galaxy Series has Edge Display/Curved Display, which increases the prospects of the accidental touch screen while putting or taking out the phone from the pocket. The side of the screen consists of the Edge apps that tend to open accidentally. So when you enable accidental touch protection on Samsung, all these dilemmas get eliminated. For now, I’d suggest you turn off Accidental touch protection and check if the touch screen is working correctly or not.

  • Open Settings.
  • Tap Display.
  • Disable Accidental touch protection.

Enable Touch Sensitivity

Do you remember how we used to increase/decrease the mouse pointer sensitivity in PC? It’s the same case, for the users with the screen protector; it might be possible that the reason behind the unresponsive touch screen of Samsung S20Plus is that thick tempered glass protector. Apparently, Samsung offers a great feature that lets you increase the touch sensitivity of the phone when you are using a screen protector to retain the same speed. Here’s how to enable Touch sensitivity.

  • Go to Settings.
  • Tap Display.
  • Turn on Touch sensitivity.

Boot Phone in Safe Mode

When all the above tricks fail, now’s the time that you should consider it as a serious problem. First things first, have you installed any third-party application from unknown source or from Google Play? If yes, then there’s a good chance that the third-party application is triggering the touch screen problem. Rebooting the phone in safe mode will help you rectify the third-party app causing unresponsive touch screen.

  • Press and hold the Power button until the power menu displays.
  • Touch and hold the Power OFF option and when asked to Reboot in Safe Mode, go for it.
  • It will take a few moments to boot the phone in safe mode, once it does, the Safe Mode will appear on the bottom of the screen.
  • You can exit the Safe Mode by restarting the phone.

After rebooting the phone in safe mode, keep your eyes sharp, and observe if the touch screen is working as before or not. If yes, then it’s time to uninstall the recently installed third-party applications until the touch screen starts working properly.

Wipe Cache Partition

Every phone has a separate partition where the system cache stores, so do the Galaxy S20. The cache files are meant to speed up the performance of the phone, but with the time passes, they usually start corrupting phone and results in multiple hidden systems crashes. Hidden system crashes may stop the primary functionality of the device, Wipe cache partition can make the problems go by deleting the old cache and adding new.

  • Turn off the phone.
  • Press and hold the Volume Up and Power/Bixby button at the same time.
  • When you see the Android recovery screen, let go of both the buttons.
  • It will take a few seconds to show Android recovery options.
  • Use the Volume buttons to navigate to the Wipe cache partition and to start process press the Power button.

Reset All Settings

To be honest, I’m not sure if resetting all settings will fix the touch screen not working on Samsung S20. But to stay on safe hands, you can try it. It doesn’t affect your personal data or contacts or anything, just the customized settings will be reset to default. Later you can customize your phone again, let’s do it.

  • Open Settings
  • Tap General management.
  • Select Reset Settings.
  • Enter the password and tap Reset.

Remove Screen Protector

Basically all the screen protectors available works with the Galaxy S20, but it doesn’t happen with unbranded protectors, yes, they will protect the screen from drops and scratches but won’t keep the phone responsive as it was before applying the protector.

I’ve mentioned this troubleshoot at the end to save a few bucks, as after removing the tempered glass protectors become useless, and you have to buy a new one.

Still, if you want to take chance, and don’t want to break the protector, then try restoring the phone to the factory settings; however, doing so will make your phone a clean slate. All the personal data, customizations, settings, etc. will be restored to default.

Restore Phone to Factory Settings

Make sure to back up the phone before performing a master reset.

  • Navigate to the Settings
  • Tap General management.
  • Select Reset.
  • Tap Factory data reset.
  • A warning message will appear, read it and tap Reset.
  • Enter the phone’s password/PIN and tap Delete all.
