Just like the old Galaxy Win, the new model doesn't really offer advanced features, though the presence of LTE connectivity is notable.
Announced in Brazil, the Win 2 has a 4.5-inch display with 480 x 800 pixels, and supports digital TV (it seems that there's also a version without digital TV). The new Galaxy is powered by a 64-bit, quad-core Snapdragon 410 CPU, further coming with dual SIM capabilities, 1 GB of RAM, 8 GB of expandable internal memory, and a 2000 mAh battery. There's a 5 MP camera on the back, and a 2 MP camera on the front.
The Galaxy Win 2 is launching with Android 4.4 KitKat on board, but Samsung will update it to Lollipop sometime later this year. Prices for the Samsung Galaxy Win 2 will start at about $230 in Brazil (mind you, smartphones are generally more expensive in Brazil than in other parts of the world).
