v3.1.1 is in the Play store and with my Mavic, the C2 wheel combo does not adjust the gimbal roll. It does change exposure though, as if the remote ignores C2 is being held.

Very frustrating!!! Does the Litchi app offer this functionality? Does theirs work?
** I should add that I tried V4 and along with the C2 combo not working there, other settings that were in V3 were also missing in V4. A good looking app is of no use if it is incomplete or buggy. From what I've seen, DJI needs to tighten up the development side of the company. Q&A seems to be severely lacking in its ability to thoroughly test new releases

@DJI Natalia, this still isn't working for my Mavic on Android. I've updated all to the latest version, Go4 app, Mavic, remote. Still doesn't work.

Are others that are using Android not seeing this behaviour as well?

Nexus 6P, Android 7.1.1, Go App v4.01, FW:v01.03.0200.
The only current remote FW version avail is the same as the Mavic, 01.03.0200.

** I just noticed you are running a P4. Interesting that it appears to work on a P4 (for you) but NOT a Mavic.

This was a function that disappeared in the IOS version of DJI Go for a couple of releases, and re-appeared in IOS DJI Go V3.0.1 onwards.

Looks like you may have discovered a shortfall in the Mavic stable.

UPDATE: I just realised that this is the Phantom group. I have started a new thread on the Mavic group pertaining to this issue. My apologies for Mavic spamming your Phantom group ;)
