Also if you switch from 4k to 1080p while hdr is active the camera app will fc. I opened a thread in bug section about that.I have found a bug maybe... with great pleasure I found in the video recording options the hdr mode but this does not seem to work, so when I record a video with active hdr and then open to see the video everything is fine but when I go back to the camera app the screen turns black and can just switch from video to photos ... hmmmmmmm -.-"
p.s.
In mi mi note 3 the camera quality is very low... much noise especially with poor lighting and much lower details than the miui 9
sorry for my bad english guys and bye bye !
