Martin Fields Screen Protector - Nokia 5800 Xpress Music - Twin Pack

Not a bad product with the exception that you need to modify the screen protector itself in order for your phone to work correctly. Specifically, the 5800's proximity sensor does not like being covered by anything, even this thin protector. The resultant effect is that when applied, you will not be able to hold/mute calls etc when on a call as the sensor senses the protector and activates the key lock. Similarly, it means that you cannot see who's calling, as the proximity sensor kicks in as soon as the phone starts to ring. I'm not happy at having to modify what is otherwise an expensive protector but other than that, it works well.
