I have this phone from last year I use it well it never hang or any other system errors don’t take place in it. It have nice Selfie camera of 5 MP whuch is perfect for Selfie lovers. It has not much HD display even 720p that thing is not satisfied me. Other things I like much that is processor and ram. It is 4g smartphone which is connected with latest era in India. I am really satisfied with this great gadget Vivo Y51l. I suggest you to buy it if you want to buy a smartphone in this price range.
