My Samsung Galaxy S Duos has suddenly started behaving very strangely. The 3g(Mobile Data) turns Off-On frequently. When I switch it on, it becomes active for few seconds and then becomes deactivated for few seconds. This on-off continues untill I switch off the mobile data myself. As per one of the forums, I uninstalled Best Wallpapers HD, but the problem could not be resolved. I have reset my phone as well 2-3 times, but the problem still persists. Please help me.
