I've had the TA1062 variant since release. The phone was magnificent and worked great without issue for the first few weeks... Come mid-May, I started experiencing UI slowdown, input glitches, and problems with an unresponsive touchscreen. Things have gotten progressively worse since the June updates, to a point where the device is almost unusable.
I also faced the issue of Touch Screen being unresponsive/Freeze. It only works when you lock/unlock the phone. Any update on your problem ?
Thank you for the response. I sincerely hope that you get your phone in working condition as soon as possible. :-)
I have the same issues, model TA1062, for three weeks it worked perfectly, I was very happy with it, then it starts to present the same touch problems you mention and right now it happens a lot, I can no longer enjoy my phone without having to lock it and unlock it every moment to work until it happens again.
