I had Android 8.1 seller and flashed the Rom Clean. The tablet starts up and I've installed some apps. After a while (1-2H) the tablet began to restart randome. Out of nowhere.
After I flashed the official Samsung firmware with Android 10 and then the Rom it ran without problems.
Excuse my bad google english.
It's just a dirty system and flashing full stick made everything fresh again.
