Samsung galaxy grand quattro is the worst phone I have used.
It is based on android 4.1.2 jelly bean which is very slow. The battery back up is also not that good u can get the screen on time about 3hours.
The camera performance is also not good.i noticed very much lag in this device.it does not handle heavy games like fifa16, asphalt8, and nova3. The internal storage is about 8gb but you will only get 5.55gb intrernal storage.the samsung should work on the performance of this phone.
