This is one of the old series of vivo.If you are looking for a perfect mobile then vivo v1 is not for you.its back camera is quit good. But front camera is not up to the mark .if we talk about money then according to prize its features are not good.Ram is good but processor is not so good.But other than this you will find some special features .It has 2 gb ram , 16 gb ROM.
Processor 1.3GZ .If you talk about battery it have 2300 mh battery . Which is a medium category battery..
Overall a good smart phone
