I purchased this product for myself. I like the super fast performance, Android OS, v6.0.1(Marshmallow), Super AMOLED capacitive touchscreen, Quad-core 1.5 GHz Cortex-A7 CPU, Geo-tagging, touch focus, face detection, HDR, panorama, SMS(threaded view). I dislike Removable Li-Ion 2600 mAh battery, Unable to change screen mode, display is selected automatically, internal storage should be 16 gb. I choose this brand over the others because I trust SAMSUNG.
