I was playing an app the other day. Crap game but addictive. I'd played it plenty of times before with no probs. However this time the phone crashed and turned off. When I powered up the app had vanished. All other apps I had downloaded wouldn't work so I had to re-install them. Now I have problems with apps resetting themselves. For example the ebay app. I used to log on and it'd stay that way. Now I log on, leave the app and go back a while later and I have log in as if I never opened the app after an install. The converter app I use, which I've used on two phones without a probelm, now won't work at all even after a re-install. This is a replacement from orange as my first Galaxy s kept freezing. Any help appreciated.
