선택된 해법

Make sure that your hands are clean and dry, then try these steps:

  • If you have a case or screen protector on your device, try removing it.
  • Clean the screen with a soft, slightly damp, lint-free cloth.
  • Unplug your device.
  • Restart your device. If you can't restart it, you can force restart your device.

Or other method

1 Restart Android Device

Before rushing into any other troubleshooting procedure, restart your Android phone or tablet to fix software glitches that may prevent the screen from functioning. To restart android device with touch screen not working:

  • Press and hold the power button until the screen becomes black;
  • After 1 minute or so, hold the power button again to power on the device.

In many cases, the touch screen will respond normally after the device reboots.

2. Remove Memory Card & SIM Card

Sometimes, faulty memory card or SIM card should take the blame. Therefore,

Power off your device (keep holding power button if the screen is totally unresponsive);

Remove back cover of your Android device and take off memory & SIM card;

Reboot the device and see if the problem is gone.

3. Put Device in Safe Mode

Corrupted or troublesome third-party apps could also cause touch screen problem on Android phone or tablet. Under the safe mode, all third-party apps that you download will be disabled. So if the touch screen works well in safe mode, then you should uninstall some of the third-party apps, especially those that were installed recently before the touch screen problem starts.

  • Power off your Android device;
  • Long press power button to reboot the device;
  • When you see the Samsung, Nexus, LG or other brand logo, release power button and hold down Volume Down button;
  • Release Volume Down button when the device boots up with a Safe mode indicator on the bottom left corner.

If your touch screen just lags or respond incorrectly, you can also try to enter safe mode in this method:

  • Hold power button until the power options menu appears;
  • Long-press the Power Off
  • When you see the message whether to reboot your device into safe mode, tap "OK".

4. Factory Reset Android Device in Recovery Mode

If the touch screen is completely unresponsive, factory resetting the device in Recovery Mode may help. However, this will delete all data in your Android device, including downloaded apps, photos, messages, contacts, etc. Therefore, use this as the last resort and if possible, have a backup to your Google account beforehand.

5. Calibrate Touch Screen on Android with Apps

There are apps in Google Play Store that can calibrate your phone/tablet touch screen and improve its accuracy and responsiveness. These apps are especially helpful if your touch screen respond too slow or inaccurately. Type "touch screen calibration" on the search bar in Play Store and you should get quite a few results. Read the reviews carefully before download.

Pressing and holding the power button is not causing the device to power down (Galaxy S8). I believe the Amazon Music app compromised the screen drivers, or that was just a coincidence of timing.

의 답변

Found my problem: For the Galaxy S8, you have to hold Power AND Volume Down to power down the phone (actually, to force a restart, I don't think it powered down)

Um, what do you do if you reset your phone and can't use the touch screen. You can't use an app like Vysor because you need to enable USB debugging.

의 답변

Hi @ Oliver Nichol,

Try connecting a USB mouse via an OTG cable, to navigate through the phone.

Be sure that the phone's battery is fully charged as it will be supplying power to the mouse and therefore will discharge more quickly.

Hi @helenr,

First try starting the phone in safe mode and check if the touchscreen works, If it does then a downloaded app is the cause of the problem. The trick is to find out which one.

If it doesn’t work in safe mode either then there is a problem with the touchscreen either a loose connection to the systemboard or it is faulty and will have to be replaced.

Here’s a link to the ifixit Samsung Galaxy J7 Glass / Screen Replacement guide, which may be of some help.

Before you open the phone to check the touchscreen cable or to replace the screen, try connecting a USB mouse via an OTG cable -example only to navigate through the phone so that you can send the pictures by email to your computer.

Make sure that the phone’s battery is fully charged before you do this, as the power for the USB mouse is supplied by the phone’s battery and it will discharge quicker than usual

If you have a pattern lock on the screen, unfortunately this method won’t work.

I’ve read a few comments here and sugest to get screen repaired. If clearing the cache on your phone or factory resetting did not fix the issue then it is a hardware issue. I was in the same position where the top of my screen didn’t work and only got worse overtime. I ended up paying $100 for lcd and glass replacement for my s8+ and is working fine now.
