QGC on android only connects after app restart after android boot

[k-kleber]

Hey :)
I have an interesting bug when using v4.4.2 QGroundControl64.apk running on a SIYI MK32 remote control (ARM64).

Expected Behavior

After launching the QGC app after android boot it should connect, but only does so after restarting the app once.

Current Behavior

After booting up the android based remote QGC only connects after starting the app a second time. So if I boot and then launch the app it wont connect, if I then close it and start again it connects fine. I tried this on 2 separate systems (2 different drones running the same software stacks) and it is so far 100% consistent.
The flight module is running Arducopter 4.5 on a Cube Orange+

Does anyone faced the same issue, have a solution or can give me a pointer to fix it in the code?

Steps to Reproduce:

Please provide an unambiguous set of steps to reproduce the current behavior

1. Reboot android device
2. have a radio connection established to the flight module
3. start QGC app
4. System does not connect
5. restart app
6. system connects
