I bought this phone on 17 sep 2014 from LOT for Rs 15400. I thought it is very good and very nice features Samsung has provided for 15K only, but after buying this I felt very bad about this phone. When I started using this I found some advantages and lot of disadvantages. Only one advantage is front camera that is 5MP and OS is Kit Kat and there are lot of disadvantages like 1.only one sim will work means it is stand by mode means when you got a cal for one sim the other sim will show not reachable. 2.It will not support for USB. 3.Headphones is very bad( the same head phones which we will get for 1500 rs mobile) . 4. Multi touch is not there means it will accept only one finger as a input at time. 5.Sound system also very bad. One speaker for all the functions like loud speaker, music player etc. Clarity is missing in music player. My suggestion is it better to go to Samsung galaxy grand 2 if you have a thought to buy Samsung galaxy grand prime.
