Z3 D6603 restarts over night while in sleep mode

[zlays84]

So I have this problem,the phone restarts usually over night or when I'm off to work and it stays inactive for 8-9 hours,regular stamina mode is activated during this...

After I'm back from work or when I get up in the morning there are notifications about restore data found on sd card and mobile data disabled which appear after phone restart...

Any suggestion what may be causing this?

Thanks!

Well I bought it at the beginning of December so its over a month with me...and as far I can tell this was an issue from the start,I did test my phone in water and all but of course with both flaps tight closed and it was fine worked well,only speakers get little bit silent but after 1 hour or so they work fine just like in my previous phones (Xperia Z and Z1) after that I used it in water few more times and everything went fine...

As for apps I use regular ones Facebook,Twitter,Messenger,PlayStation app,PS4 remote play and other Sony and Google stock apps...I didn't knew about SmartConnect thing just did what you suggested...

If it restarts again I will try to repair my software to se how it goes...
