Overall, it is a very good smartphone from VFM perspective except actual battery backup which is much less in real life than claimed by Samsung. Also sometimes it hangs so have to do a reboot through battery pull ... got to know from many friends that most Samsung phones hang a lot especially the Grand Duos series but this one doesn't hangs that much in comparison ... so having a good experience!
Among the good brands this was, till date, one of my most preferred VFM phone under 15,000 before...

Very Good service by Flip-kart,

Come to product its totally disappointed ,

While playing a video i was getting a line on screen but not with normal screen, but only playing video i found it ... so not satisfied with product

This is my second samsung dual sim android phone, and once again a bad experience. It's about to complete 6 months since purchase and already a lot of problems have started to happen. Portable hot-spot not working, Phone rebooting on it's own, charger not working properly and hell lot of problems. This phone made me believe that dual sim phones are not worth to be bought. Never going again for samsung/dual sim phones !!

>As I buy this mobile 5 months before and now it is not performing good, as it is working slow, just I can say it is hanging,
>Another issue is that its make is such that it's Camera is getting scraches and full of Dust,
>And It has no option of transfering Apps. from Phone Memory to SD card memory,
If Company could develop some OS to do so it make its' customers happy !

A quite great smartphone but the major problem comes with battery and moreover the apps don't run smoothly.

This is good product and good service by seller. I am happy with it.
Not so bigger in size and weight. its 4.7" screen makes the view precious. totally its amazing....

This product restarts by itself many times a day when you are using 3g network. This problem is not only with my mobile but with all the users who are using 3g network with Samsung grand quattro. No fix has been Provided by Samsung. No factory setting can fix this bug. Even customer care reinstalled new firmware in my mobile 2 times but still same problem.

since the day, i started using it. It is giving trouble whenever i was using camera of this phone. At first, it got hang when i made the flash of the camera on. from last 2 days, whenever i tried to start the camera, it is displaying the message " camera failed" and the phone becomes hang and i have to restart it again. Did not expected this from a product of samsung....

i bought this phone from mobile store.
