Just a word of caution.....
Not QuadLock specific and not phone specific, but phones with magnet based optical image stabilisation do not like their cameras being subjected to repeated high frequency vibration for long periods of time - for example being attached to motorcycle handlebars. That's most of the current generation of high end smartphones with advanced cameras.
I have used Quadlock for many years now, without issue. But, the camera on my old iPhone X started "focus hunting" after a while. Apple fixed it for free. Then I got an iPhone 11 Pro last year, and a few weeks ago it started doing the same thing. They will fix it for free again, but it's not ideal.
I think it may indeed be down to bar vibration as the first it happened was right after I took the phone off the bars of the bike.
Anyway...however you go, I would make sure there is at least some isolation between bars and phone. I ended up buying a Garmin XT for nav as I don't want to kill any more phone cameras.
