Samsung Galaxy S Duos 2 is a version of Samsung Galaxy Trend Plus with dual SIM Android smartphone, produced and marketed by Samsung Electronics, which serves as an immediate successor to the original Galaxy S Duos, which is made in second quarter of 2012. Unveiled on 30 November 2013 at some Asian markets, it was initially released on December 5, 2013 in several countries. In contrast with other dual sim Samsung models, this phone is a part of the high-end "S" series, this is why it is marketed as a part of the "Galaxy S" family. Despite being called as a direct successor to the original S Duos phone, external and physical design of the model is identical to the original model, placing emphasis on internal upgrades such as upgraded processor and updated Operating System software.
The design of the S Duos 2 is the same as the design of the S Duos. It features a rounded, polycarbonate chassis, faux metal trim and a removable rear cover, typical of most Samsung smartphones since the Galaxy S III. The S Duos 2 is available in Black, and White frost color finishes. The S Duos 2's screen is a 4.0-inch (102 mm) 233p TFT LCD panel, which is the same as that of the S Duos, but does not allow for automatic brightness and gamut adjustments due to lacking an ambient sensor like its predecessor.
Galaxy S duos 2 has a 5-megapixel camera with LED flash and 0.3-megapixel front-facing camera. The rear camera has 7 shooting modes. This rear camera can record video in 720p, 480p & 240p.
Unlike entry-level dual SIM models from Samsung, the S Duos 2 is active on both SIMs all the time so it is ready to receive calls on either SIM when a call is not already in progress. Optionally it can receive two calls simultaneously, but this requires divert-on-not-reachable to be set up on each number and is subject to availability from the carrier and may incur additional charges. A limitation of the phone is that only one SIM can be active on UMTS (and therefore data) at a time and so it may be unsuitable for certain combinations of networks.
The S Duos 2 also contains a 1500 mAh removable battery. It lasts somewhere in 4–5 hours in heavy usage and just over 3 hours in gaming.
The S Duos 2 ships with Android 4.2.2 "Jelly Bean" and Samsung's TouchWiz software. The S Duos 2 adds some of the Galaxy S4's features such as the widgets which were upgraded to the Samsung proprietary widgets used by models bearing the version of the OS. Officially there is no plan for further upgrade but unofficially many custom ROMs built by developers SandPox, Ishant Vivek and others. ROMs can be downloaded from xda-developers forum or latest daily builds from SandPox's Jenkins
