Right... I recently bought a Sony Xperia Z1 handset (not new, to my knowledge it has had a motherboard replacement from an authorized service), and I am facing a very annoying error:
Whenever my screen turns off, as in locking the screen, the phone will almost immediately reboot. While I have music playing with headphones connected or while I am in a Skype call, the phone will work just fine.
Before you try suggesting software updates, I'll have you know I tried every possible method out there, including PC Companion software updates and repairs, OTA, even going as far as to manually flash a ROM using Flashtool. I also attempted soft and hard resets and booting in safe mode does not work. Also, the phone does not have a valid warranty and I have no authorized Sony service in my city (or country if I think about it). It doesn't look like the problem is software related. It's just that whenever I lock my screen, either via the power button or through the screen timeout, the phone will reboot.
If anyone knows how to fix this error, I would greatly appreciate it.
