The Hero appears to use 5GHz Band C which is too high for most devices in Europe. New Apple devices and new Samsung flagships seem to work. Your device might be able to do it with different firmware of if you root the device.
GoPro don't think this is a fault.

I searched in some communities and the situation is really a disaster: gopro 7 has many connection problems with the Android device:
- connection unstable
- connection slow
- only 2,4 ghz available
