I just purchased a Samsung galaxy s4 (T-MOBILE Version) and would like to know if it's authentic or not, since there are so many fake clones out there so I'm not sure. If anybody who owns an authentic samsung galaxy s4, please help me out here by posting some specs or characterizations or any solid fact that can prove mine is real. And if anyone has any tips, please do post on this thread. Thank you so much! I will really appreciate your help!
