Samsung Mobile device has a blank or black display
If your phone or tablet displays only a blank screen, there are a few things you can check to determine the cause of the problem. For example, your device's battery might be dead, or maybe it just needs to be reset.
Check for physical or liquid damage to the phone, tablet, charger, and USB cable.
Check for corrosion and bent pins on the USB connections. Examine the Liquid Damage Indicator (LDI). The LDI should be either all white or all white with pink or purple Xs. The USB connection should be firm and have little movement.
Remove any cases or accessories that may have covered the charging port or buttons.
Note : If you use the biometric security feature, the phone will require your backup password to unlock after rebooting.
here are two ways you can force a restart on your device:
- Press and hold the Power key (or Side key) and Volume down key for 20 seconds.
- On devices with removable batteries, remove the battery for 60 seconds, and then reinsert it.
Connect the phone or tablet to the proper charger and charge it for at least 1 hour. It may take up to 10 minutes for the battery charging indicator to appear on the display.
Disconnect the phone and then attempt to turn it on by pressing and holding the Power key (or Side key) for 15-20 seconds. The Samsung Galaxy logo will appear.
- If the screen turns on, your device needed to be charged. Turn off your device and reconnect it to the appropriate charger until it's fully charged.
- If the screen fails to turn on after performing the previous steps, your device needs service. Contact the Samsung Support Center for further assistance.
