The phone Xolo era is a very good phone as I too have that mobile phone and I am using it from many days. it has quite good camera in the price range of Rs. 4500, while the front camera is much better. Touch sensitivity is also very good.
The battery backup is great with 2100 mAh in the price range mentioned. Supports good amount of new features.
But there was problem while doing a software update for the first time the update ended with an error saying "no command". And my mobile phone had to be submitted to the service centre for more than a week. Only this problem I faced yet else Xolo era is the very good low budget phone.
