My phone works but my screen is blank

 Hello,

Recently I had a same problem.

My phone screen goes blank/black but the buttons (power, home) and bottom lights are still working.

Strangely, the phone works just like usual. It still can receive calls, messages, chats or any notifications, but the screen is black/blank maybe that's caused by some system problems/errors that affect the screen.

My phone is not using extension batteries, so I can't remove them because the batteries are sticks into the phone (like Apple iPhone batteries). I tried to restart the phone by holding the power button for a minute, but that doesn't work.

If you had a same problem and same phone type as me, here are some solutions that might help based on my experiences:

1. You can wait until your phone batteries are dead, then recharge and restart the phone.
2. You can restart your phone by holding the home, power, and volume down buttons together. (If volume down doesn't work, try volume up.)
3. If solutions 1 and 2 don't work, please go to your phone services center.

Hope that helps.

Have a nice day.
