Hello friends, I use this phone, in this phone user interface is very nice. there in no any option for video calling if you want to video calling you must to download app. no updated operating system. front camera is not good clarity. but the rear camera is batter than the front, in this phone one problem is that heating problems are facing when charging the phone. touch is better but not smooth. clear calling sound but not clear music sound. in this phone battery backup is pretty good.
