Vivo s1 is a budget smart phone with starting rate of 18, 000 .
It has 6.38 full hd screen and the first in indian mobiles comes with meditech helio p 65 octa core processor.
It also comes with AI trippl rear cameras and 32 mp front facing selfie camera .
It has high fast 4500mah battery with charger.
It is a good budget mobile but it will be more good if it will be around 15, 000 starting rate so it will be the best option.
Whereas it also have fingerprint display scanner which makes it more smarter
The case was also so beautifully made and phone also have earphones.
By the way I dont like it so much as its just an average.
