Compass / Magnetic field not working on umi touch (gps works fine)

gambler02

Hello everyone,
I just noticed that the compass on my umi touch is not working, when I open any compass app when I move the phone the compass does not move at all,
I also dont have a heading arrow in my google maps app, GPS seams to work fine as it shows my position even when internet is off, when I walk to another place the position dot also moves, but no heading arrow.

This is a screen shot of my google maps app without the arrow :

The arrow on my phone is not showing

This is how it should be :


Does anyone know how to fix that? Is that a magnetic field problem?

Regards

There is no sensor for a working compass.

The antenas were not touching the hardware. The solution was something like this:
