I recently bought a vivo v17 smartphone and there is no doubt that it is an amazing smart phone with very innovative and useful feature.its design is very slim and attractive, its has 4 cameras which makes its back locks so damn good.if you are fond of photography then you should buy this phone because it gives a great photography experience.vivo v17 has a power backup of 4100mAH which gives you very much screen time so that you have not to charge your phone again and again.it also gives you better sound experience which I loved the most in it. vivo v17 is a bit expensive, but if you want to have this much fearures so you have to pay for it.and all I want to say is if you want to invest your money on smartphones then please invest it on vivo v17.thank you.
