I bought this second hand phone on OLX but it is still under the warranty . Sound quality is ok but pretty satisfaction . The S7 is a very user friendly phone . The always on display is very useful for checking time and notification without having to turn on the screen . The curve screen just amaze me even more, Love watching videos and check pictures on it. The screen is just unbelievable
S7 is really cool device, S7 has 5.1 inch quad HD display, 3000 Mah Battery, 12 mp rear camera and 5 mp selfie camera is really nice takes wide selfies and cover lots of scenery. I Love fast wireless charging feature, it charges almost to full within 1 hour. It has a lot of amazing features like waterproof, able to increase memory, excellent camera feature and so on . I can recommend this in any forum . Samsung is one of the leader in mobile industry and having good reputation . overall a good phone, 100% value for money
