This is one of the worst mobile phone I have ever used, it has many disadvantages, the first problem I faced was the device heating problem, then next problem was the battery backup problem .
after charging, within few minutes the battery starts discharging .
this phone laggs a lot, games cant be played on this device, as many times the phone switches off with no reason .
even it has a quard core 1.25 it never runs smoothly, always laggs
no sim gives good network in this device, this phone also has network problem.
and the worst part about vivo is they never assist their users properly
so I would never recommend this device.
I would give 1 out of 5 stars .
