Sometimes when pressing an icon on the screen, the press will not register. This usually means that the screen needs recalibrating. To do this, youll need a pin or a paper clip to press the reset button located on the top left hand side of the screen. It is a pinhole reset button. Push the reset button using your pin/paper clip and the same time, the Home and the Unlock buttons on the right hand side of the screen (see image 1 in Red).

Then once you have done this, the calibration screen should appear (see image 2). Using your finger, press each of the calibration targets and do you best to press as close to the centre as you can. If a press has been successfully registered, it wil move on to the next calibration point on the screen starting with each corner of the screen and ending with the centre of the screen. When complete, you will get a message suggesting that the screen is now calibrated.

You should now be able to press and successfully register against an icon on the screen now.
