It runs Adroid KitKat with EMUI. The system works really fast without any lag or other disturbances. Installed is indeed a library Quad Core + 1GB Ram. What all the possible applications and apps really fast load. Surfing the net and working smoothly.
The 8MP main camera shoots beautiful pictures, the 2 MP useful Selfies.
