I was using my phone normally and suddenly green line appeared on the left aide of my screen. I don't know what samsung has been doing. Firstly issue with network and now the green line. NOT SURE WHAT'S NEXT IN LINE-UP?

Facing severe network error after updating to October Security Patch. Unable to register on Network. Only Emergency calls available.

After I installed One UI 5.1 update. There's significant heating issue on my device is observed which is affecting battery life.
