4. Just after I updated my system (first time happening)
So I was using phone just fine then I decided to update it the system since there is an a available system update, after updating Ive noticed that my phone is not reading my sim card and suddenly auto rebooting. So far what Ive done is force restart, taking out my sim card and putting it back and not trying to commit anything big. I assumed that this is because of an update so please please can you fix this ASAP?
