I using Vivo V3 handset from 1.5 years and there is no problem facing from the purchase of this product. There will be no hanging problem as well because it has 3GB RAM and Octa Core Processor so, it good for the user. But there in the system update when there any update coming it will be after long time and in the update there will not a big change it will be android version and any other thing. Otherwise, it is good product to it running and it’s camera quality of primary also good and it’s front camera to the other phones. So, it would be good option to buying this product.
Thank You
