I am using this phone for 1 year and 6 months. I advise all of you do not use ASUS phone. Within 1 and half years I faced lot of problems: -
1) My phone screen was shattered and I have to replace by paying out of pocket.
2) I had replace back panel twice
3) I had issues with Camera
4) I had issue with 1st sim slot and had to replace the same that out of pocket.
I have decided not to use ASUS any product in my life time. I warned & advise you to stay away from ASUS if you want to save time and money.
