Here we have high resolution USB charging ways solution for the Galaxy A20s smartphone. This ways solution will show you how to jumper and bypass the OVP ( over voltage protection ) chip (sometimes called voltage regulator or current regulator).
The OVP can become damaged when too much usb voltage or current is passed to the charge IC of the A20, or after water damage, it is safe to jump this component if you need to power on the phone to get data.
This can fix fake charge problems but won’t fix the PMIC U1301 if it has problems, this solution is only if no 5V USB power is getting to U3101 and thus can’t charge the battery.
