I'm using a Redmi Note phone for display only.. I noticed this update and did it as usual as I have had good stable flying till now. I didn't use the Mini2 for a week after updating it..
I flew it locally as I often do but the video feed back to the display was updating around every two or...
I have just tested v1.4.12, and the bug is real. The relative direction of your drone to the controller/compass pointer on the lower left is dead as of now.
No such issue before with v1.4.8 (1120) and v1.4.8 (1185 beta). I guess there is nothing much to do except wait for DJI to fix it.
