I It has been a year using the samsung galaxy s5 3g variant.The phone is fast but sometimes lags after gaming.Tge phone battery life is average saying it excellent would not be good.The CAMERA is the best I found on a average phone.Samsung being a big brand focuses on the camera.Both front and rear cameras are great.Other sensors like fingerprint, proximity, heartrate sensor are just great.I would like to say that the phone lacks the 4G connectivity which is popular now a days.The phone price is being cutoff at arrival of new model as other brands.GREAT CAMERA PHONE.
