Using it from past 1.5 yrs, and till now I observed that it is has some some great specs like intel processor, 2 GB ram etc but its UI( zenui) cant handle them properly,
Some more work is required to be on Zenui by asus, the only department where Zenui works good is the its camera, pixelmaster technology handles the camera quite well.
Instead of having 2 GB of ram, there is no difference from the phone with 1 GB OF RAM. Either its hardware is not good or zenui is unable to handle 2 GB, I dont know the exact reason.
So, this can be a good pick but some now a days, some more phone with better specs are in the market at the same price point.
