cpu one is not really a problem, it's either a bug in trascription that won't affect the usage or they really use 1.5ghz (6753 supports it on full power)
camera at 21mpx is interpolated, so a fix for a 13mpx resolution is needed in upcoming updates.
I agree with @benson about the cpu bug, but a bug is a bug. It needs to be fixed ASAP.
And there is a camera problem which is really a problem. Another user @Daywalker815 has also informed Admin about the 21 MP Issue.
I hope they release another FOTA update within a month.
Dear,
For the camera, the 21MP is interpolated pixels, the true pixels is 13MP, we will set another option of 13MP in the camera
For the CPU speed, we use the CPU: MTK6753, The speed is between 1.3GHz and 1.5GHz.
