Asus is one of the super smartphone available in the market at affordable price. It has nice design. Its sound quality is superb. It has a reasonably good battery life. I promise you this is one of the very best smartphone you can buy. It has 5- inch FHD, IPS Screen, Qualcomm, Snapdragon 630CPU, 4GB RAM, 64 GB storage, 12 Megapixel Sony IMX 362 image Sensor with a secondary 8 Megapixel, 120 degree wide - angle lens, rare camera, 3300mAh battery, Android 7.1 Nougat with Zen UI. The mis-range Zenfone 4 is Asus latest flagship smartphone. With pricing starting at affordable price, it targets the same segment of the market as the stellar Oneplus 5, which to date is Trusted reviews recommended handset. I was a little less impressed with the Zenfone 4’s color calibration, however.
