I recently bought a Nokia 5230 .. in june 2010..
It worked really well for one month..
Yesterday.. i started experiencing unresponsive touchscreen problem.. The touchscreen didnt respond .. and the Small white menu (with the music,web,share icons ) kept popping up .. if i moved my phone a little bit..
I did a Soft Reset as well as a Hard Reset .. Nothing worked out..
The touchscreeen works after i lock and unlock the phone..
