Situation: After upgrading Android V11 to V12, DJI app doesn’t work anymore. You just can’t open DJI app.
Resolution: A new version of DJI GO 4, with support for Android 12, is now available to download direct from DJI: https://www.dji.com/ca/downloads/djiapp/dji-go-4 (sorry the forum won’t let me make it clickable).
