This worked for me. I'd been having this issue for about two weeks. I booted into recovery, wiped the cache, rebooted, and it hasn't happened since. Samsung chat support was a useless bot. Grateful for your help!
Hi Mack55, I suggest you please reboot your device in safe mode and check if your device still restarts.
To do this, you need to completely power off the phone. Then, power on the phone, and when the Samsung logo appears, press and hold down the Volume Down key. If done correctly, "Safe Mode" will display on the bottom left corner of the screen.
