Hi! Has anybody experienced white / green screen for days up to more than a week on their S20 Ultra? Noticed this happenning frequently after installing a new software update.
We are sad to hear that you're experiencing this issue with your Samsung Galaxy S20 Ultra where the screen turns white or green for extended periods after a recent software update. Please try the below steps to fix the problem:
Force restart the device: Hold down the Power Button and the Volume Down Button simultaneously for about 10-15 seconds until the Samsung logo appears. This will force the phone to restart and may temporarily fix the issue.
Booting into Safe Mode disables third-party apps, which can help determine if the issue is caused by one of these apps.
Press and hold the Power Button until you see the power off icon.
Then press and hold the Power Off icon until the Safe Mode icon appears.
Tap Safe Mode.
If the white or green screen issue doesn’t occur in Safe Mode, it may be caused by a third-party app. Try uninstalling any recently installed apps.
Sometimes, a software update can cause issues with cached files. Clearing the cache partition may resolve this.
Turn off your phone.
Press and hold the Volume Up Button and the Power Button simultaneously.
When the Samsung logo appears, release both buttons.
Use the volume buttons to navigate to Wipe Cache Partition and press the Power button to select it.
After clearing the cache, reboot the phone.
If nothing works, as a last resort, please perform a factory reset. Backup all your data before doing this, as it will erase everything on your phone.
