Hello everyone

I have a Samsung A20 with root access

---CPU-Z---

-Model SM-A205G (a20ub)

-Board exynos7884B

-RAM 2725 MB

-Available 660 MB

-Internal Storage 22.95 GB

-Available 10.12GB

-Android 11

-API 30

-Kernel aarch64

I was using the GPS in the car with the cell phone on the windshield on a very hot day with really shiny sun. The phone overheated and turned off by itself. It was actually really hot, I had to wait to turn it on again and continue my trip.

After that, on the same day, I continued using the device (keeping it away from the sun) and it worked properly.

However, from the next day on, the phone started closing apps and turning off several times, with a message saying that it was overheating. Although, by the touch, he's always completely cold.

When I took it to technical assistance, I was informed that the board would probably have been damaged by heat and could not be fixed. I started using the device with several restrictions, avoiding the GPS, disabling automatic synchronization, dimming the screen...

I tried to solve it by cleaning the system, reinstalling the ROM but the problem persisted.

I wonder if anyone here knows a way to disable the battery temperature sensor or at least interrupt its monitoring to try tricking the system.

I installed a logcat monitor to capture a moment when it restarted and the result was as the following:
