Chosen Solution
I have an A50 that started claiming that it was overheating and wouldn’t charge. I tried: Factory reset - No change Clean charging port with pin, IPA, q-tip - No change Remove rear cover - Minor water damage on some chips on charging daughterboard, and on the main board. Replace midframe - No change Shorting the 2 pins on the side of the motherboard that corresponds to the power button sometimes lets the phone turn on depending on what is connected. Cleaned water damage with IPA and q-tip - No change
Removing these three PCB components resolved the problem for me. I used a soldering iron and managed to get them off in the end. https://fixpirate.com/samsung-a20-a205-o… - This shows a very similar process for a very similar board from the Galaxy A20. Buying a new charging port should also fix the problem properly. I believe this solution may merely removes the phone’s capability of detecting the temperature, and as such, buying a new charging port is a recommended solution.
Remove them or replace them?
