Hello all.....I have a new Walmart Samsung galaxy s 2 on t-mobile service prepaid $50 and can't understand much without instruction book. I am not tech savy and don't understand why YouTube will not play or buffers way to much. Am I supposed to find a flash player and try to install it to play video? I tried from Google play and nothing would or seem direct. Please help if you can I need support. This is my only connection to interent and I understood I would put my sim card in from a Samsung Dart and go....but I am going nowhere instead. This NaNa sure would appreciate you help and suggestions on what to download to this crazy phone before it jumps back in the box and finds it's self back to Wally World.
