I used this phone for 6 month only but till now the service of this phone superbbbb! this phone can easily handle heavy games like asphalt 8 airborn, nova 3 etc. also the battery backup and and camera quality is pretty good but at night the picture taken by the camera is slightly disappointed me but over all the phone is best at this price range. when I got my phone then the os is Lollipop and its don’t support the volte but after the OTA update I got mashmello and also volte supported and also my battery consumption is low after the update
