I have used this smartphone since 2 weeks .the main thing they concentrated was on the selfie and rear camera .a smartphone is to run apps and games but this is not like that. It cant even run heavy apps and games the ram is slow and processor speed is very low .its average on atutu bench mark and hated it has storage and hd display but not full hd .dont buy this if you are a hard core gamer . If you do simple tasks on it you can surely buy this. The customer services is good. the good model of vivo I liked was v5 and v5 plus. Remember its vivo camera and selfie .so only they gave first importance to camera .i recccommend to buy lenovo .coolpad .redmi .as there are many iffers available on this smartphone it supports volte also . Its your choice now
