I have been using the phone for the last 7months. I am a satisfied customer of Asus. I have never experienced a single problem from the phone. The best section of the phone is the camera and the processor. It has never lagged for a single instance. I have the 3GB model with Octa-Core processor. The camera is 13MP with dual tone fash which gives natural colour output( camera with single tone flash tends to take yellowish pictures) . The front camera is 5MP. Both the camera of the phone is excellent and I am delighted with both natural daylight pictures and low light environment. One small cons is the battery it drains quickly though it has a 3000mAh capacity it does not last a day with heavy usage. The touch is very responsive. Overall, for all the reader, if u are looking for a phone within Rs13, 000. I would suggest everyone go for it.
