Thank you for contacting DJI Technical Support.
Sorry to hear about the trouble setting the histogram as well as the overexposure features on your Mavic 2 Pro. I definitely understand that you've already performed a few troubleshooting steps and still facing the same issue. I am here to help look into this for you.
If you're still unable to set the histogram and overexposure feature on your aircraft. I suggest performing a few troubleshooting steps that can help fix the issue. I understand that you might have performed some of these but I suggest performing it again:
1. Clear the cache of the DJI Go 4 App on your mobile device's Settings.
2. Try to re-link your aircraft and the remote controller, you can visit this link and follow the on-screen instructions on how to do so.
3. When activating the overexposure feature and histogram, just tap on the switch till it turns green and not sliding the switch.
However, if the troubleshooting steps provided still doesn't work, kindly provide the requested information so I can raise this with our Engineers
1. Firmware Version of your aircraft.
2. Version of your DJI Go 4 App.
