I would like to share my worst experience with this phone. I purchased this phone specially for battery back and camera quality, however, I was not satisfied with both the things. Also the after sale service is very poor, they do not have any service center with Asus name. They do provide after sale service through other service centers and they are difficult to find.
The wait time is very high, you need to wait for at least 1 month for your phone to get repaired.
At last, I would recommend you to not to go with this brand because after sale service is the biggest thing and it is the future of every stable brand.
