Question My phone isn't turning on

[pepsimanlo]

I'm currently using an Oppo, and was watching a discord screenshare when suddenly my phone started flashing blue and turned off.

Now when I turn it back on the system is working but the screen just remains black.

What do I do?

Welcome to Android Central! Which Oppo phone? How old is it?

How do you know it's still working? Does it make sounds, but just doesn't show anything on the screen?

Well, it's an Oppo A57s that is over a year old.

It's working because when I hold the power button it makes a vibration even when the screen is simply just black.

See if you can boot into Safe Mode: https://www.hardreset.info/devices/oppo/oppo-a57-5g/safe-mode/

Let the battery charge for 4 to 6 hours on slow charger see if it wakes up , because it vibrates doesn't mean the battery can't be bad it may have enough juice for vibration but not turn the screen on which requires lot more power.
