Phone losing touchscreen focus after update.

[Manas Gupta]

My stock Lumia 820 didn't have any problems,but after updating to firmware 1308,my phone randomly freezes,and I have to lock and unlock again to regain touch response.Even the touch buttons on the phone stop working.Anyone facing the same problem?It's getting really annoying.

Have you tried hardreseting your phone?

Not yet.Is there any possibility of data loss?
