I have been using this phone since long back. Almost a year I guess. I ll tell you abt the phone.
First of all.when this was launched it had set milestones in online sale market.because of its price and features.a 2gb ram phone a year back was a big thing.not all sub 10k segment phones used to come equippes with such power packed features.
The updates also come to this handset.through cyanogen.UI is very good as cyanogen allows almost all types of customisation like.the normal ones.and the cyanogen specific ones( onscreen buttons choice, themes choice that includes status bar icons and even you could change the boot animation which is not possible on other phones without root)
The things that demarketized dis YU phone is its shitty kind of battery backup, its rear camera and its speakers.they r not loud at all.
Rest other things are above average.high end games work like charm on this handset.thanks to its processor and tge 2gb ram.
The camera could have been much better.
Note: - YU gives you warranty even when rooted.!
