if touch screen is not working restart you phone and try to calibration test and if hardware problem then you should have some knowledge of repairing and find here the hardware solution of Nokia Asha 311 touch screen solution

I am having the same problem.

You need to recalibrate. Try pushing B, A, Hint, and Home when you turn it on. Do not have a cartridge in the player or it will think it is a regular Leapster. Once it says calibrate screen it will say to press A, then wait until a target appears in the upper left hand corner, touch it and you should hear a sound, then a new target appears in the lower left hand, repeat actions, then lower right hand screen, and finally the upper right hand screen. If it stops at any time and doesn't get more arrows, try it again or turn it off and see if the pen works. It may take a few tries to get it to recalibrate correctly.

I'm not familiar with the Zumo family of GPS from Garmin, but if they are similar enough to the StreetPilot, you should be able to recalibrate the screen. In the StreetPilot series, to recalibrate you turn the unit off. Press and hold the bottom right of the screen and turn the unit on. Keep pressing the screen until the calibration information begins. Try this, see if it works on the Zumos, too.
