I have use this phone for more than 1 year and had no issue.
It was very good phone in cheap rate and their features also vary good like palm selfie it means when u take selfie u can see ur palm and it take 3 second to take ur picture.
It has a 8MP primary camera, 5MP front, 1.5GB RAM , light weight, amoled display, wifi etc.Different type of themes avilable like samsung basic, craft, sweet, natural, classic.
In this phone u can use 2 dual sim but problem is that if u can use 2nd sim u can't use the meromy card.In short this mobile is very good and I am satisfy with this mobile.
