What should I do if the OPPO phone has a black screen but the phone is turned on

Solution: If it is a removable battery, it is very simple, pick the battery (of course, you can also try method 2 to solve it), and then restart, it can basically be solved.

If it is a mobile phone with a non-removable battery, you need to press and hold the power button for about ten seconds (some mobile phones are forced to shut down: volume up or volume down + power button, press and hold at the same time), generally the mobile phone will vibrate slightly, indicating that it has been turned off.

Turn off the phone and wait for about fifteen seconds, then try to turn it on, if the boot is normal, then you need to do a normal cleaning of the phone to avoid this problem again.

If the phone cannot be turned on after many attempts, or the screen is still black after multiple attempts, you need to contact the local after-sales service. Note here that if the phone is under warranty, don't disassemble it yourself, so as not to trouble it at that time.
