I had a bit of a problem with my protective screen...
I peeled off the backing and applied the protective screen and it seemed to be firmly stuck and I was apprehensive about how I would remove it at a later date but everything seemed OK.
I put the phone in my pocket and went to football. I must have put my plastic glasses case in the same pocket for about 10 minutes and later when I looked at my phone the screen was all scuffed up. I thought I had ruined my brand new X1 and this put me in a very bad mood.
When I got home I managed to remove the protective screen with no difficulty whatsoever which was a big relief.
As it happens I had purchased 2 protective screens and when I examined the spare I realised that the screen came in 3 layers and the top layer was just ordinary plastic which scuffed easily.
So I applied the second protective screen by peeling off the backing layer, applying the screen and then peeling off the top layer and the results are excellent.
The first screen had attracted dust and debris and could not be reused.
I recalibrate my screen by pressing as lightly as possible during the calibration and the performance is excellent.
