im trying to do long exposure on the mavic but i dont see the time setting on the manual exposure.running latest app and updates on nexus 6p AND note 3

ran into this video but mine looks different. doesnt show the time setting.

You have to slide that slider where it says "M" from Auto to Manual.. then it will give you all these options. Also, you have to be in photo mode, not video.

Are you using an iPhone? (thats what the guy is using)

Please try what Mir said.
