First of all I am using it since 8 months and still typing this review on the same phone.
It has 64 GB of internal storage, I have used it completely still there is no lag or hang from the device, I can safely recommend this phone to anyone.
Front Camera is awesome it’s you can’t expect anything more. Moonlight camera is working fine. Auto focus, Face beauty, Slow Motion, Time lapse, HDR is inbuilt you don’t need other apps for that, you can shoot 1080p resolution videos.
Cloning of app is made easy you can have 2 whatsapp, facebook, twitter in same phone. The notification comes on screen when you’re watching video so that multi-task can be done easily. Screen Shot option is inbuilt you can select the portion of screen and take a shot.
