I purchased this product for myself. I like this product because of Super AMOLED display,
Quad Core processor, Auto Focus, Accelerometer, Geo - Magnetic Sensor, Hall Sensor, Light Sensor, Proximity Sensor, RGB Sensor, Touchwiz, Wi-Fi Direct, ANT+ Connectivity. I dislike this product because of Android KitKat 4.4, Expandable Storage 64 GB, 8 megapixel camera, Network Type 3G, Nano SIM, Battery Capacity 1900 mAh. I choose this brand over the others because I love samsung.
