I purchased this product for its 4 gb ram. I like this product because Android 6.0 Marshmallow, 5.7-inch QHD display, 21 MP rear camera, dual-LED flash, 8 MP front facing camera, 2.15 GHz quad-core Snapdragon 820 processor and 4 GB RAM, 32 GB internal storage, 4 G, Wi-Fi 802.11 a/b/g/n/ac, Bluetooth 4.1, GPS, NFC and a micro USB Type-C reversible port, non-removable Li-Ion 3, 100 m Ah battery. I dislike nothing much but the price is little high but its o.k with the features. I choose this brand over others for its high camera and dual flash.
