Samsung planning to unveil a cheaper Galaxy Note 3 Lite at MWC, too
As for the Galaxy Grand Lite we already told you Samsung is expected to up the specs from the original in some respect, putting a 5" 480x800 pixels display, 1.2 GHz quad-core processor, 5 MP camera, 1 GB of RAM and a 8 GB of internal memory, plus a 2100 mAh battery. This makes the Grand Lite sit somewhere between last year's Grand and the Galaxy Grand 2 that was just unveiled, keeping the dual SIM functionality.
Now as to why would Samsung do something like that with the Lite versions, the answer is pretty simple, akin to what the Koreans are doing with the Galaxy S4 mini - they capitalize on the Grand and Note brands built around the success of their representatives, and build cheaper versions with lower specs that will appeal to more people. Let's not forget how LG also introduced a dual SIM G Pro Lite, which dials down the specs (and the price) of the original G Pro, while keeping the screen size.
