The Asus Zenfone 4 is budget android smartphone with a 4" screen has 1 GB RAM / 8 GB internal storage.The Zenfone 4 is pretty small by today’s standards, which means it’s very easy to hold and use. Images measure only 2560x1440(16:9) by default, but you can choose the larger 2560x1920(4:3) if you prefer.
Despite the low resolution, my photos came out surprisingly sharp and clear. The Zenfone 4’s battery life is good, but it’s no where near as impressive as the Zenfone 5. I have owned this since last year and it hasn’t given me any problems but constant daily joy to use. This is a very good brand and I highly recommend this Asus Zenfone 4.
