Yu is a sub-company of a well known Indian company micromax.When my father bought this phone from amazon is cost us about ₹7000.As it was the best spec we can get in that budget.
Performance wise it is just nice, yes it lags a little now but its ok.It has Snapdragon 410.
Built quality wise it is one of the best it has a cool metal rim frame.And has GG3.
Speakers are not good but they are loud.
Screen is preety nice it has a nice 720p display.
One of the best thing of it is cameras- both rear and the front are really great and are able to shoot some amazing pctures/selfie.
But, after 2 years of usage it is having a issue.Whenever we call from sim 2 it restarts.so thats all .Thank you
