Herelink controller

Hi everyone,

I’m using a Herelink 1.1 ground controller, which currently runs Android 7.1.2. I have QGroundControl installed, but the current version available for this Android build doesn’t support MAVLink message signing.

The newer QGC v5 supports signing, but it requires Android 9 or higher.
Is there any way to upgrade the Android version on the Herelink 1.1 to make it compatible with the latest QGC version?

Thanks
