My 720 getting stuck, apps opening without touch...

[barcafan]

when i start using..it functions very smooth.. after a while it get stuck, types on its own etc..
tried soft reset, hard reset etc..
found out when i press near the top of phone screen near sim tray part some apps get opened, same while i press below window button..
Worst part is these doesnt happen all the time.. so wondering how to explain to nokia guy:angry:
Guys got any solution for this..?

the screen is frozen..not the side keys... when i press hard on top or bottom part of screen again it gets activated....:amaze:
i am kind of doing research on this..
but the issue started happening 2-3 weeks back, mostly after amber...

I would say your only option is to take it to Nokia Care. Explain to them what the issues is. Hopefully it will do the same there aswell...You already tried most things that you can, now it is up to them.
