I’ve seen that vid before but there appears to be a fundamental difference in the way my drone-only android phone works when compared to my iPhone X.
The video makes perfect sense when you refer to the iPhone behaviour but my android ‘radar’ behaves in a totally different way and nothing like the YouTube vid or my iPhone.
I might just stick a SIM card in it and drive around for a bit and see what it does. I remember a few years ago having a Galaxy S6 Edge that never pointed in the driving direction - it always managed to point to the 10 o’clock position when driving straight ahead. Something like that could be responsible for this behaviour, I guess.
