As of know yu has launched many phones but heither of them are upto the mark. They make very huge commitments of their phone but nothing is working . I know I am saying some negative things about yo .but thats true.
I bought my phone on 1st of march 2016 and it has been approx 1and a half month ihad used it. But the main problem I faced was that the fingerprint was not working and that ram management was poor beside having 4gb of ram . processor given can not heavy games such as nova 3 .modern combat 5 with some minor lags and frame drops throughout the game.
