I will share my experience about asus recently lauched zenfone 4 selfie single camera. The display of the mobile is very bigger, with curved screen. But there resolution is only HD, not even the fully HD. The resolution is poor, because screen is bigger and resolution is very less. The finger print sensor, was not response quickly, it was little slower in sensing it. In this mobile, the processor is nice, but not so good, in this range of mobile phone. The camera take very sharp picture in this mobile. Both the camera comes with 13+ 13 MP camera, but the camera quality is poor in low light picture. The sound in this mobile is lounder, with doubly sound quality. The sound range is also longer. This mobile is little difficulty to use it, because the interface is different. The style & design is very simple, and made of plastic which was poor at this range of mobile phone. In this mobile, various photography feature mode is given for shooting. The look and feel was bigger in hand, but not very good in hand grip. The mobile is little expensive, so the mobile is not value for money for me.
