Hi, Developer_XYZ , i have they same issue, would you be si kindly and share with me they apk’s? Thanks in advance. My email is prusaker@gmail.com
It looks like the problem is showing up on newer versions of android. On a smartphone with Android 7, the program works fine, but does not work on another phone with Android 11 
Test results from my side. Drone - DJI Mavic 2 Pro. Smartphones - Nexus 6 (with Android 7) and Xiaomi Redmi 10 Pro (Android 11).
Nexus 6 with Android 7:
Pix4capture v4.5.0 (with Ctrl+dji v1.9.6) works fine.
Pix4capture v4.7 (with Ctrl+dji v1.9.7) works fine.
Pix4capture v4.11.0 (with ctrl+dji v1.9.9) - ctrl+Dji doesn’t connectet to drone with message “DJI SDK error”
Thus for old smartphones, it is enough to roll back the Pix4capture version to 4.5.0, 4.6.0 or 4.7.0.
Xiaomi Redmi 10 Pro with android 11:
Pix4capture v4.7 (with Ctrl+dji v1.9.7) and newest releases doesn’t connectet to drone with message “DJI SDK error”
Pix4Capture with releases 4.5.0 - 4.6.0 - just don’t connected to drone without any error messages.
That is, none of the versions of the Pix4capture works on this smartphone (with Android 11)
Thus, the problem is most likely in the interaction of the ctrl+dji plugin with new Android versions (Android 11).
