Well, I updated the phone and my camera stopped working (video mode).
Tried all (reset, repair) but no change so I've sent to the official Sony labs. They replaced the motherboard and camera (???).
When I tried the phone, almost no GPS signals. Gave it back to the lab and they did software update (I didn't see any when I got back the phone).
Tried again the phone, and again, no camera and no GPS.
I've sent it again to lab. They told me that they gonna change the motherboard again.
Can someone explain if an Android update can cause all of this?
