I own this phone from past 4 years it’s best of the gadget I have brought but only fault I observed in this four years was its battery performance! it really a doesn’t last for a hour if I switch to 3G mode or if my gps is switched on!
Battery drains too quickly!
apart from battery another draw back is that it gets heated up very soon n being a medal body you feel the heat really sooon.
After the jelly bean update my Xperia got slow, I could not answer phone calls, the call log took so much time to appear,
I have tried uninstalling external softwares, reseting the phone, nothing worked. Finally I have downgraded the phone
