Asus ZenFone Z010 It’s very good mobile phone. As I am using this mobile from last 10 months. In this mobile phone the camera quality is very super. And talk about RAM it runs Smoothly, Actually but sometime it hangs frequantly. And the bettery backup is awesome, if charge it 100% in the morning, then you can use this last long day and night. Best mobile to buy. Thank you Asus
