Hello everyone, 

Anyone facing automatic reboot of XZ1 since the 4.3 update? i noticed it happened to me 4 times in total now.

I suggest that you to run your phone in safe mode for a while to check if you still experience this. If not this may be caused by any downloaded application.
How to boot into safe mode?

I was going to post the same problem soon... It has happened 5-6 times to me since the update to 4.3... Please fix this automatic reboot which occurs when I unlock from the lock screen... Sony Support waiting for reply
