The Galaxy Core Plus is almost exactly similar to its predecessor, the Galaxy Core. The Core was an interesting mid-ranger phone; because it is one of the few reasonably-sized handsets in this price point. Where many phones have displays that are 5-inches in size, the Core and Core Plus adopt a rather comfortable 4.3-inch screen size with an 800 x 480 pixel resolution. The Core Plus is powered by an undeclared 1.2GHz dual-core processor, 768MB of RAM (which is less than the Core's 1GB), and half the internal storage of its predecessor (at 4GB vs. 8GB). We suppose the chipset may not be very powerful, as the Galaxy Core can only record videos in 480p non-HD resolution. It's got a 5MP camera at the back with an LED flash, and a VGA front-facing camera. Its got an 1800 mAh battery; which given the low-end specs, should hopefully prove adequate. It runs Android 4.2 Jelly Bean.
Samsung Galaxy Duos 2 is the upgrade the popular Samsung Galaxy Duos 7562. The same 4-inch screen (800x480 pixels) has been used, which bears a decent pixel density of 233PPI. The single-core processor in the older one has been replaced by a 1.2GHz Dual-core processor but the same 768MB RAM is found in this one as well (which although is more than the typical 512MB you get in this range, but phones like the Moto E have started offering 1GB, and it’s no secret that more RAM is always good). The 5 megapixel camera with flash is largely the same as its predecessor, except now it can record HD videos at 720p. Moreover, there is secondary VGA (0.3MP) camera for video calling and selfies.
The phone runs on Android v4.2 Jelly Bean with TouchWiz UI. The phone supports 10 languages including Indian regional languages. The smartphone supports Dual-SIM (GSM+GSM) 3G connectivity and offers Bluetooth, WiFi and GPS as well. It has an internal storage of 4GB (of which about 2GB is user available) and it has a microSD card slot which support memory cards of storage upto 64GB.
