Im using this product from 4 months, mobile is awesome, but many of the apps like there in android are there in windows, that is only one negative point in this, and some apps which are there in the store also not working like cortana ap, it is showing that the app is not available in my area. and there is no sharing option except Bluetooth there is no faster transfer apps in the store, there is shareit app in the store but it is not working when installed in my phone. and while coming to camera front cam is better than back camera, and the camera clarity is not there in dark time, flash is also not capturing good quality pics, this is only better in day time and good lighting conditions.
there is no option for the changing phone ringtone
