My phone just developed a fault. There is this white/green bright light on the bottom part of the screen.  Sometimes blinking and sometimes stable but always bad for my eyes. Please I need help with solutions. Thank you.

Re: Malfunction

Hi there!


Does this symptom still occur when testing your device in safe mode?


Let's try putting the device in Safe mode to determine if there are external factors that cause this symptom. This step will temporarily disable all your third-party apps, but none of your personal data will be deleted. Your customization settings (Wallpaper, Themes, et cetera) will be reset to default once you exit this mode.


Please follow the steps below:


1. Turn the device off.

2. Press and hold the Power key past the model name screen.

3. When "SAMSUNG" appears on the screen, release the Power key.

4. Immediately after releasing the Power key, press and hold the Volume down key.

5. Continue to hold the Volume down key until the device finishes restarting.

6. Safe mode will display in the bottom left corner of the screen.

7. Release the Volume down key when you see Safe Mode.

8. To exit Safe Mode, restart your device.


Let us know how your device responds after performing this step!
