Hi guys. Had my desire s about 6 weeks or so, but having a bit of a problem with it constantly turning off. what started as a once very few days thing which I could deal / initially put down to me accidentally turning it off, has now turned to a constant issue, with the phone being off nearly every time I go to it. I have little doubt I will have to take it back, but the problem is that I have no idea what's causing it - and have never seen it do it, meaning I can't replicate the issue. There is no pattern at all, other than I finish using the phone, turn the screen off, and then when I go back, it's off. Sometimes I'll get a HTC Crash notification, but not always. My suspicion is that the power button is sticking or something, as it doesn't feel like it's clicking - but as I say, I can't replicate it, so can't be sure. Has anyone else had anything like this & know what the cause was, so I can at least point it out to the shop staff? Thanks!
