Omnia frequent loose of vertical screen calibration

[Guest latreto]

Hello,

Since a week ago my Omnia started loosing the vertical calibration of the screen. I realign the screen but after normal use, the vertical precision is half of centimeter below the right place. I do the calibration, and it goes OK for a while and then again y loose the vertical calibration.

I really do not know what is causing this abnormal behavior.

factory rom, windows mobile 6.1. Spb mobile shell 3.0, spb phone suite and spb keyboard installed

I am trying to avoid hard reset. Any hint?

Regards

Rafael
