Samsung just announced a new phone back in December 2012. Most of the phones offered by Samsung are just single SIM. If you are a fan of Samsung, you might have known that Samsung has not released many dual-SIM phones. Well, Samsung Galaxy Grand Duos is different. As the name says, it is a dual-SIM phone as you can noticed by the Duos extension in the phone name. The phone continues using the design that the Samsung Galaxy SIII has introduced and some people says that it is Samsung Galaxy S III! In this review, we will cover the whole phone if it is really worth to be a clone of Samsung Galaxy S III.

Built, Design and Display

As have mentioned earlier, the Samsung Galaxy Grand Duos has the design and finish of Samsung Galaxy S III but more likely to be a clone of Samsung Galaxy Note III because of its screen display. The rear cover of the phone has a beautifully mosaic-like pattern that makes to mask most of your fingertips. In terms of the screen, you will see that the Grand Duos does not get the traits of its origins that has a Corning Gorilla Glass protection. Why? The Samsung Galaxy Grand Duos protects itself with an LCD display that is more brittle compared to the Gorilla Glass.


On the screen display of the phone, we can say that it gets the Galaxy Note II’s screen because the Grand Duos has a 5.0” Capacitive TFT Touchscreen that can display 16 Million colors. In terms of the pixel per inch density, the Grand Duos is pretty bad with this feature. The Samsun Galaxy S III has a 720 x 1280 pixel with 306ppi density, the Samsun Galaxy Note II has 720 x 1280 pixel with a 267ppi density and for our thing, the Samsung Galaxy Grand Duos has a mere 480 x 800 pixel with a 187ppi density.


If you are going to compare the screen display of the Samsung Galaxy Grand Duos with Samsung Galaxy SIII and Samsung Galaxy Note II, the Grand Duos is really no match.




When the Samsung Galaxy Grand Duos first announced in public, many users complain about the low-resolution screen of the phone. With the 400 x 800 pixel with 187ppi density, it is not as bad as one can think. The Grand Duos runs on Android 4.1.2, which is also known as the Jellybean along with the TouchWiz. The UI of the phone is more likely to be on the Samsung Galaxy Note II with some of the features of the Samsung Galaxy S III – Multi-window, Pop-up play, Smart Stay, S Voice and some really quick motion-based gestures are all presented in this phone.


The smooth flow of the interface can be credited to the ARM Coretex-A9 MPCore SoC. This thing comes with a dual-core CPU running at 1.2GHz each along with 1GB of RAM. The SoC also has a support for NEON video decoding extensions and ARM TrustZone technology. The GPU is not the normal Adreno or Mali chipset but a Broadcom Video Core IV.



The Samsun Galaxy Grand Duos may not have the famous Wolfson audio chip, but this thing does not spoil out giving us a good media experience. Audio quality is decent with earphones as well as the loudspeaker. The volume level of the phone is good and watching movies as well as watching music videos are enjoyable.


The video player of the Grand Duos is very functional and it supports most formats like AVI and MKV. You also have the screenshot feature along with the feature to tag your friend in the video, edit it or even set a timer to switch off the thing automatically.




The camera of the Samsung Galaxy Grand Duos supports a powerful 8-megapixel front camera with Back-Illuminated Sensor (BSI) and LED flash. The image quality is very decent and really presentable. You can record a crystal clear 1920 x 1080 (1080p HD) resolution. The user interface and the feature of the camera is very much alike on the Samsung Galaxy S III.

If you are worried about self-shot or video calling, don’t worry because the Grand Duos has a 2-megapixel front camera. Image quality is good enough for a video calling. If you are trying to have a phone with a front camera more powerful than the Samsung Galaxy Grand Duos, or to say, a higher-resolution, you will have to look around over and over the internet just to find one and even if you found one, the features of Grand Duos is still much better compared to that phone.



 The Samsung Galaxy Grand Duos is really a good phone with good features. Though it may be awkward to have a phone with dual-SIM support, you can have the Samsung Galaxy Grand that is the single-SIM version. Though we still doesn’t have the news about the operating system of the phone, for the one who is concerned if they can upgrade it, the Samsung Galaxy Grand Duos is still worth to have.
