This is common issue in Samsung A50 and other similar phones where the battery charging is stopped and a temperature warning messages is displayed on the screen when plugging in the charger. Moreover, the phone won’t turn on with the remaining power in the batter.
Today, I received a Samsung A50 with the above-mentioned issue. The problem started after the phone got some water spilling over it. I opened up the phone and diagnosed properly. I didn’t see much signs of water residuals inside the phone apart from a tiny sign near the charging PCB at the bottom of the phone. Here is what it was showing on the screen while plugging in the charger:
Fixes I tried
Cleaned up the PCB with the cleaner, the problem remained the same. Replaced the charging connector, still, the issue wasn’t resolved. Meanwhile, one thing I noticed that the phone would turn on if I remove the charging PCB. However, it won’t turn on when the PCB is attached. So, this was clear that the problem is with the charging PCB only.

So, as I figured out the issue was with the charging PCB only, I replaced the PCB with a new one. Here is how the PCB looks like:
After replacing the charging PCB, the issue was fixed and the phone started charging properly. Here is the proof:
Although, this fixed was tried on Samsung A50, it would work on other similar phones like Samsung A10, Samsung M30 or any Samsung A and Samsung M series.
