As I said, the phone restarted itself to upgrade and disabled the notifications until I loged in again. I could have missed some important stuff, but I notice it before it caused a problem.
So I went to the configuration and disable automatic upgrades.
Now I get a notification that ask me to restart to upgrade, and say that if I accept it will be restarted automatically next time. (And it's very easy to press that button by mistake.)
And there is an annoying that each week tells me if I used the phone 5 minuthe more than the previous week, and is magical and impossible to turn off.
I've owned 2 Samsung smartphones and both have had issues the same hardware issue. In the older phone it was a known issue so the repair was only $20, but with the new phone I think it'd be a couple hundred more
