I am using this phone for almost 4 years.
This phone has a very strong body and a decent performance .
This phone have a decent battery life and the call clarity is also good. But I had to root the device for solving the hanging issue which I had for last 2 years.
The camera in this phone is also good for outdoor shots but in the indoor shots the camera was struggling very much.The side chrome is not so good as it started ripping from the phone and not giving the grate look to the phone.
The phone is very thick(9.6 mm). The storage is one of the biggest issue since we get 8 GB of space on the phone but the usable is only 4 GB and after installing the apps we are left with just 1.50 GB of space, and if u install large games like FIFA 15 the does not get installed in the SD card it gets installed in the phone memory, If e try to transfer the apps in the SD card only some part of the app is moved to the SD card.So I think the phone sucks in the memory department, and in the ram which is memory management part it just gets 800 MB of RAM which is so good for multitasking, since Samsung introduced this phone with split screen multitasking I think they should have given at least 1.50 GB of RAM. I think that this phone is kind of a good phone with decent performance.
