The Grand Duos looks like a Note II clone, but it has the finish and build of the S III. It feels strong and durable, but is on the thicker side at 9.6mm and is quite well at 162gm. Just like the other Galaxy handsets, the sensors and the front facing 2 megapixel camera are on the front. Underneath the rear cover, we have the two GSM SIM card slots and a microSD card slot. For the first set of devices, Samsung has bundled a separate rear cover with a flip style screen protector. As it turns out, the 5-inch screen’s 480 x 800 resolution is actually quite good. The phone runs Android 4.1.2 jelly bean along with TouchWiz and the interface is quite smooth. Smart Stay and 5 voice are present. The fluidity of the interface can be attributed to the ARM Cortex-A9 MPCore SoC. This consists of a dual core CPU running at 1.2 GHz with 1GB of RAM. The GPU is a Broadcom Video Core iv. Samsung manages to deliver a great overall media experience with the device. The video player supports this device. The video player supports most formats including AVI and MKV with full HD 1080p playback. The Grand supports external storage upto 64 GB.
The Grand duos is quad band GSM handset with tri-band 3G support. You also get dual band Wi-Fi Direct, GPS with A-GPS support and GLONASS, DLNA, and Bluetooth 4.0, tv out and NFC seem to be missing, but we doubt they will missed much. You can set dual standby for the SIM cards and also configure which SIM should use 3G.
The stock keyboard works well and in split-screen mode, you get a floating keyboard that you can position anywhere on the screen while using both apps. The Grand’s 8 megapixel sensor is accompanied by an LED flash and outdoor shots come out really well with good detail and accurate color capture. Indoor shots were also good and there was a little noise. The Grand manages macros well too. Video recording maxes out at 1080p and you have the option of adding filters as well.
The 2100mAh battery puts on a very good show-the Galaxy Grand ran for nearly 8 hours and 40 minutes in our video drain test. This is very good if you frequently watch videos on the go. The battery life will be lesser when both SIMs active, but even so, we feel you should easily be able to pull off around 16 hours of actual usage.
The Samsung Galaxy Grand Duos is priced at Rs.21,500, which makes it a very good buy owing to its dual-SIM feature and its functionality. It has very good media capabilities, a good battery life and a good camera with full HD recording. It also has most of the features of the note II, like split-screen mode, and packs all of this in a pretty well built body.
