Loved my Xperia Z until the 10.5.1.A.0.292 update. Now I will surely switch back to Samsung.
My Z is unusable after charging: system lag, touch not responding, keyboard not responding, camera working slowly, battery drains faster then before etc. IT'S A MESS!!! Always got to reboot, but this doesn't always fix the problems.
.283 was working great. Sony, why rid you ruined it?!
PLEASE FIX THIS ASAP WITH A NEW UPDATE OR TURN BACK TO. 283!!!
If not, I promise that I'll never use SONY again in my life!
