I finished playing games (phone did not get too hot) then pressed the power button to turn the screen off.
It opens Camera instead. Calls and messages can't be received. I tried Shutting down or Restart in the dropdown menu but it is no longer an option. The phone did not straight out freeze, but cannot complete its tasks. I tried plugging the phone to my laptop, but it was nowhere to be seen in File Explorer.
This has been the second time I've experienced this issue. The first was about two months ago, and the phone finally did an automatic restart after thirty clueless minutes. This time around, I had to force restart.
The thing is it happens around midnight. Both times. Right when I was heading for bed. This error, presumably a firmware/software issue, takes nearly an hour off my six-hour sleep. I don't want to be harsh but I really don't want to pay a premium price for a once Samsung flagship to behave like this.
It is two in the morning and I wonder when it comes next.
Feel free to ask for more information.
