Cannot view main screen

[malayo]

After a while, usually my betouch e140 will turn off its screen to save power but lately it would not go back on after i pressed home or pick up call or close call.

I had to press pick up call for a few seconds to power off and power on again, then the problem will be resolved for a while.

Any ideas?

Android: 2.2

Solved.

It was because it got really slow response after i installed phandroid app.

Had to hard reset.
