I got a Galaxy Tablet this past Christmas and was very disappointed when the bottom four buttons (menu,home,back,search) did not work right out of the box. But I also got the keyboard as well so I could use that to go back and search etc. But now just recently it has been searching and going back to the home when I am in the middle of an app. And it does this repeatedly now, pretty much making it unusable and leaving me very disgusted with it. Is this a common problem with these or did I just happen to get a bad tablet.
