Dumb SMARTPHONE. I was not aware that this phone is using Tizen version instead of Android version, I bought it but still cant use it no whats app, Facebook, internet, share it etc it shows "the file type is not supported by any application on your device" and sum sending it back - it is beautiful but no good ugly looking as well as worst features. Samsung how can do such a blunder. worst phone. Worst camera. Worst battery backup. cant install from other sources. what the sarcastic decision by Samsung manufacturers. friends dont need never buy this. Waste of money.
