Very good product. No issues sofar. Perfectly working till today.
There is no software upgrade since I purchased the phone in May 15. Even dealer says that this is a outdated phone which will be soon stopped by Vivo
I have vivo y28 it's very best mobile &no hang and camera result us wonderful but only and only 2 problem 1== battery life is small 2== price is highly for this feature
Nice performance good metallic body ,Crystal clear camera and stylish look
With my openion the all set of vivo comapny is too good....same as vivo y28 4 gb is best mobile for me.
