I used Yu yureka for a year and this is the best smartphone I used so far.
It costs Rs.8999/- and is very reliable.
It has 2gb RAM And 16 gb internal memory.
Android version is lollipop.
The rear camera is 13Mp and front camera is 5Mp.The image quality is really awesome and clear.
The best thing of this smartphone is that it contains Cynogen Operating system which you a wide range of customization settings.
It is very easy to customize everything on status bar , navigation bar, etc .
The battery backup is also awesome.
There are a bit heating issues but only during charging.
The gaming experience of this smartphone is awesome and really good graphics.
I recommend you Yureka if you are in search of a new smartphone for its reliability.
