This phone is good in design and features. I purchased it in December 2015. It runs on Cynogen OS 12.1 which is powered by Android 5.1.1. Since it runs on cynogen, the UI is much better than Android UI.
The features are very impressive according to price. 16GB storage, 2GB RAM, Octacore processor. 8MP camera clicks very good quality pictures and videos.
The battery life is very good. I loves playing online games. I play Pokemon Go for 2 hours, Clash of Clans for 2 hours, Marvels Contest of Champions for 2 hours. I use Jio4G and never close my data. Still the phone battery works for whole day.
The interface is very smooth. Light weight. Run all apps I ever installed. Browsering is very fast. App installation is very quick.
People get bored after using the phone for 1 year. The phones also becomes lagy. But I am still happy with my phone even after 1 year of usage because it is still working like new. I recommend it to all who are looking a phone for ₹7, 000.
