I have been using this Samsung Galaxy S plus for over an year which has an android verion 2.3.6. Lately I have observed a strange behaviour, that when the device is on GPRSor using data package, the apps keep closing automatically, which becomes quite annoying while surfing net or using google map on the move... Any one knows what can be the problem. I have reset to the factory settings also, but no success. I have scanned the device using 2-3 Anti-virus software still nothing detected. Any suggestion, what could be the issue/resolution ?
