There is 13MP AF camera with flash on the rear and 5MP on the front. is If you remember my Redmi 1S review with reference to the camera lags, well I faced the same on the Note 4G. The camera will work without any issues as long as the battery temperature is below 35 degrees. But it doesn’t take much time for the temperature to raise to above 35 degrees and that is when the camera starts to lag heavily. It will take it own time focusing the subject and what ever you see on the screen (the lags) the same will be recorded.
