I use samsung S22 Ultra as my primary phone and my old S20 FE phone to mount on my motercycle for songs and navigation. The auto hotspot feature helps turning on hotspot on my primary phone without taking it out of my pocket. Everything is perfect in this setup except when I have to attend or make calls.
One UI already has a feature called call and text on other devices. But it is only limited to watches and tabs. I think this feature must be extended to mobile phones also. It may be a small thing but very useful for motercycle community.
