It is smooth while new but after some days it hangs.
It supports otg but it causes virus in the phone and even after connecting it with laptop the laptop begin to shiver like it has been instantly attacked by virus.
The phone and android does not give system updates instantly and security updates is very rare to be updated. Its body is made up of fibre which can be eaisly smashed after numerous falls on the same place
I will never recommend to take this phone.
