Asus smart mobiles phones are simple and wonderful. The mobile built is very good quality, good shape, sound quality, screen resolution is good. I am using the phone from last 18 months . Now also I cam see the same ram speed and good battery backup. Worth for the money we spent on it. Many of the other popular brands selling at a high price for the same configuration. don’t go by attracted towards the fancy tv adds and end up spending lot of money.
