I bought a $600 samsung watch, still under warrenty the thing would heat up and shut down. Went in for repairs, when I got it back it did the same thing, heat up and shut down. I took pictures with timestamps and date. Samsung now says case is closed because there is nothing wrong with the watch. I have proof, but they ignore it. Switching to iPhone. Had to many problems with samsung phones, tablets, and tvs. Their technician says ", then test with the outgoing quality control software and show all pass" ... really? Does it look like nothing is wrong? Maybe something is wrong with the technician??? Its obvious! Samsung has horrible reviews. Cost me lots of money. On phone for over an hour then get disconnected. Once I went to Walmart and back while I was on hold, when I got home they disconnected the line so me holding onto the phone was a waste of time.
