I have used yu yunicorn moblie its performance is very bad.
Problem in just a few days of moblie buy.
Sound problem, charging problem, jack pin problem so many hardware issuse in this phone.
And when an application installed the screen is automatic turn to black and white. Its software issues in this device.
The costmer care service is also very bad. And it takes too much time in repairs.
Yu yunicorn moblie is not successful for these reasons.
