No matter what I try, I cannot get the Histogram to come on or the AFC to stay on.  I have tried all combinations of video modes.  Can anyone offer some assistance?

Hi, Sorry for the troubles that it caused. May I know what is the version of your app? Would it be possible if you can provide a short video of it? You can use google drive or dropbox then provide the link here. Did you try to uninstall and re-install the application? Ensure that the files are saved and flight records are sync before deleting the app. Please let us know on the latest progress for further assistance. Thank you for the support.

Are you talking about how certain camera settings don't stay enabled after restarting the aircraft?

No, I turn everything on and get ready for the flight.  I got into the settings and turn on the histogram, but it does not appear in the Go App.  The option turns itself back off as soon as I leave the menu and the histogram does not appear.  I have only tried with a Galaxy S8.

Go app, or Go4 app

Go4 app.  I think there may be an update but I cannot figure out how to do it on the Galaxy... it is easy on the iPhone.

I have exactly the same problem as Hemlock: the histogram doesn't appear on screen and the green button to enable it goes back to white immediately. I use Go4 app latest version.
Same problem with the zebras for highlight warning: nothing happens when i turn it on

Hey Justin, I saw that you replied to my problem and wanted to give you my "fix"   I know it is a pain, but if you reset your controller you will be able to get those features to stay on.  Just write down your settings before you do.   Cheers and hope all goes well.

Hey Hemlock,
have you solved the AFC problem?
it happens to me that as soon as I activate the video recording, AFC stops working
the only way to keep the video in focus is to do what you need to do with AF, ie tap the screen

I also have exactly the same problem: the  Histogram & Overexposure warning  doesn't appear on screen and the green button goes back as soon you leave setting.
I use Go4 app latest version.
DJI's "technician" told me because I am using Samsung Note 9 & they are note compatible , however  users w/Galaxy S8 have the same problem.
I should say that technical support has become much weaker than it was 2-3 years ago.

I'm kind of having the same problems.  Tech had me reset my camera settings and I did get the histogram to work but the AFC goes back off as soon as I get back out of the settings.  Are I-Phones supposed to work better with DJI technology?  I have an S8 but right now might consider getting the I-Phone 8 if that would work better.

Same here. Only I'm using a brand new zoom with a 2 month old upto date smart controller. I was Tring to get the appiture to lock so it won't go darker as I zoom in and out. But that lock won't work. Nor will histogram stay on.

Same here, brand new Mavic 2 Pro with a Crystalsky monitor. Historgram and AFC turn off when I exit the menu.
