Troubleshoot a screen that isn't working
correctly
If your Android phone or tablet's screen isn't responding, or if you're seeing flickering, jumping,
flashing, dead pixels or a blank screen, try these quick fixes and troubleshooting steps.
After trying each recommended solution, check to see whether it fixed your issue.
Step 1: Check your device's screen
1. Make sure that your screen isn't cracked, chipped or damaged.
2. If you have a case or screen protector, take it off.
3. If you're wearing gloves, take them off.
4. If you've put any stickers over the screen or sensors, peel them off.
5. Make sure that your screen is clean.
Step 2: Try these troubleshooting steps
If none of the quick checks above worked, try the troubleshooting steps below.
Restarting your device
To restart your phone or tablet, press your device's Power button for about 30 seconds, until
your device restarts.
Rebooting your device gives it a fresh start. Sometimes, that's all you need to fix an issue.
If your touchscreen is still completely unresponsive after restarting your device, you can find out
how to reset your device to factory settings (below).
See whether an app is causing the problem
The problem may be caused by an app that you downloaded. To see whether a downloaded app
is causing the problem, you can reboot your device in safe mode.

1. Turn on safe mode.
2. Once you're in safe mode, touch the screen.
oIf your screen works in safe mode, a downloaded app is most likely causing
your issue.
1. Restart your device to exit safe mode.
2. To find the app that’s causing issues, uninstall recently downloaded apps
one by one.
3. After you remove the app that's causing the problem, you can re-install the
other apps that you removed.
oIf your screen doesn't work in safe mode, continue to the next section.
Test the affected part of your screen
If the issue happens only sometimes, or only on a specific part of the screen, you can use the
notification shade to confirm. The notification shade is the panel that you can swipe down from
the top of your screen.
1. Touch the top left corner of the screen.
2. Slowly drag your finger to the bottom right corner without lifting. Try to move your
finger slowly enough so that you can count to 10 before reaching the opposite corner of
the screen.
oIf you can drag the notification shade all the way to the bottom of the screen
The problem isn't caused by a specific area on your screen. You can find out how
to reset your device to factory settings (below).
oIf the notification shade releases while you're still dragging your finger
across the screen
Repeat the test. If the notification shade releases again, note whether it happened
in the same place on the screen.
If your device is a Pixel phone, find out how to get help.
For other devices, please contact your device manufacturer.
