I am using this mobile since from 6 months this works very fine
small small features like starting tourch without opening lock of xiomi phone.
dual app is also exellent feture in which we can have multiple apps to be installed in same moblile phone e.g. two whats app applications can be installed in same mobile.
child lock is also a better feature which gives protection against data loss by child. when our clidrent wants to use our cell phone then we can turn on child mode to protect our important message, phone numbers, phone galary, and so on
