I have a samsung galaxy tab 7.0 plus and its been acting a little strange the past few days... I was hoping that I could get some suggestions!! I use Dolphin Browser HD and sometimes when I have more than a couple tabs open it will just close the browser and when I go back in, the pages that I had up aren't there anymore. Then sometimes it will freeze and the touchscreen wont work and ill have to hold the power button til it shuts off and then turn it back on. The part that has me really worried is that a few minutesnago it just completely rebooted by itself! Suggestions please? I have Lookout installed but I don't have the Premium version...
