Well this phone is not very good. No 4G connectivity in this mobile. This mobile has very old os version that is android 4.2 jellybean.
Now a days in a smartphone atleast 6.0 mashmallow must be present there. Vivo has no satisfied his customers. RAM is only 1 GB and processor is only 1.2 ghz.
If you are looking for a smartphone under 10k than you have to go to other companies like moto. This mobile has somehow heating problem which is not good for a regular user.
If you are a good gamer then I suggest you to not buy this mobile.screen quality is not up to mark so over all this mobile is not good.
