I dont know if its just me but Ive had this phone for 3 months now and its a good phone. My only complaint is that the phone is very slowespecially when playing games I mean this phone is supposed to be an upgraded version of the J5 but it cant even play temple run 2 without a few stutters. Im not 100% sure but I think its software related considering even my old phone with a dual core and 512mb ram ran more smoothly then this. Unfortunately even after 2 updates there has been no fix hope Samsung addresses this problem soon. If anyone knows what this might be me or has similar issues please let me know if I should return it to Samsung.
