I own an S21 ultra for about a year and a half now. I worked well until I update to Android 13/One UI 5.0. It keeps restarting itself while Im using it or whilst just sat there. Sometimes during me opening the camera, watching youtube or checking Instagram, just anytime could happen. It really frustrating that i cant do anything about it. I even factory reset my phone, but the issue still persist. Has anyone else had the same issues and solved it yet?

SAMSUNG SORT IT OUT!!!!!!!!!!!!!
