I found a bit of dust in the camera window and noticed that the plate behind wasnt well attached. I sent to the mobile service and they say I have to pay 250 for electronic work (without any explanation) and my warranty is canceled because I modified the software. So in the end they did nothing and returned (I pay for the back!) With a ratio absurd "the menu does not work." So they stole the SIM tray and refused to return it. Cétait three months already without my phone because of the "Sony Xperia" Care "". I read on the forum that the screen may break and the "service" will say "it's because of your use."
