OK folks, let's make this clear.
There are 3 software components.
AC firmware
Rc firmware
App version.
Firmware version of AC and RC is not relevant to the issue so please, no more references to firmware when discussing the change of indicators.
What is relevant is the app and it's version. DJI has the orientation indicator up to and including app version 1.2.1
With version 1.2.2 DJI removed the orientation indicator and replaced it with the attitude indicator.
With iOS, the app is usually updated through App Store, often automatically
With Android, the app is updated through Google Play, again often automatically
However this time, for whatever reason, DJI did not distribute the app update through Google Play. Instead you have to obtain the update by downloading from DJI site and installing.
The app cannot update itself like it can update AC/RC firmware.
