CONVERSION

I have an A50 that started claiming that it was overheating and wouldn’t charge. I tried: Factory reset - No change Clean...

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-over-heat-charging-paused-solution/ - 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.

I’ve had this happen when using the wrong key for my car (the one without the immobilizer). Check if the immobilizer light on the dash stays on or blinks before or after starting your car.
