Last week on the way to work, my colleague who also has a Z1 used my phone to look at something and his first comment was "Whats up with your power button??"
It has no definite feeling when pressing it, its almost impossible to tell if you have pressed it or not, it looks and feels recessed too.
When trying his phone it was exactly as I remembered it to be, when you push it you can feel as response (small click or resistance), on mine there is nothing!
So I contacted Sony Xperia, who were suprised by the described issue. Long story short I have to return the phone to them for a 5 - 7 day turnaround repair.
Anyone else had the same issue? Or even sent their phone back to Sony in the UK? I am a little concerned that once it is prised open to be repaired it will never be the same again! All in all, for the £550 I paid for a premium handset, it is the first one that I have had any hardware issues with.
