Ever since I updated to .55, the proximity seems to be a problem. When I end the call, the screen is still off. I have to click unlock button to lit it up again.
Any one facing this problem. The problem is only when ending the call. It is also bit slow in turning on the screen when I unlock the phone.
Music stutter is still there.

These problems have been in every release for the UK SIM free version of the Xperia S since last August not to mention the camera only working when it can be bothered and then that is only when it isn't moaning about running out of memory.
The Xperia S was the dearest mobile phone mistake i ever made and although i have been using a Nexus 4 (which by the way is a pleasure and a delight to use) for a couple of months now i cant ever find it in my heart to forgive Sony for the £420 they were happy to take off me and then not support or fix with any urgency.
My daughter is fuming that she also bought a SIM free Xperia S and it is a shambles to use with its constant problems.
