i repair my mobile by pcc as you said but still there is a touch problem. In starting the touch works properly but after 5mins it hangs and touch stop responding.

That's probably a third party app acting up

touch is working but too hard..And i installed only whatsapp And opera mini. the touch is very hard mostly while typing.

Boot on safe mode and use the phone for couple of hours, if it works fine then it is a third party app
