Counter intuitive, I know, but our phones these days are NOT "solid state". At least the cameras in the "better" phones are not. Assemblies in the lenses that include image stabilization on the physical side ofthings, shifting the sensor or the lens alike, and of course the auto-focus systems in the lenses, do not like the violent vibration transfer that a really rigid, all-metal mount will subject them to.

It is one thing to have that phone in your pocket or bag while riding a bike/moto, and a completely different thing doing it when it is super-securely mounted on a handlebar with a metal base that has zero "give".

I had a phone's camera die on me like this, using a more forgiving mount (quadlock) than this seems to be on my MTB & Gravel bikes.
I would avoid mounting my expensive smartphone on my MTB, if I had to do it, I would use a mount with some short of "suspension" and as soft a mount possible to absorbe some vibration with flex. An alloy mount with zero padding might look slick, but is the exact oposite from that.

100% accurate. The mount I use has rubber isolation and can seem slightly floppy but it's fully secure and just absorbs the harsh jarring.

Are you saying the Quadlock was too stiff for your phone, leading to damage?

That is what I attribute it to.The phone's (Galaxy Note S20U) main camera would get its main ("1x", high MP) lens assembly stuck. It could not AF. Shaking it hard would 50% of the time get it unstuck and would work temporarily. Others have reported similar issues with other Samsung and Apple phones at that point in time. I do not try to blame Quadlock for this, it did what it was designed to do and I had 2 generations of phones before that, which "survived" unscathed. I simply stopped mounting the phone on the handlebars of my bicycles, which i am riding in singletracks and whatnot (lots of high frequency chatter, some abrupt drops and jump impacts etc) which is probably much more violent than commuting on a moto or bicycle on even bad pavement alike.

I have an el-cheapo Aldi rubber mount for my phone on my mountain bike, it is TOO sloppy, and I'm afraid it will go flying. I am an upper intermediate rider, I guess. For home trails it doesn't matter, but when I'm exploring new areas I'd love to find a good mount.

Other option is to just use an old phone with pre-loaded Trailforks and not worry about it, I guess.

I have a Garmin Edge computer with preloaded Trailforks. Yes, it is $, but so was the Quadlock: some $70-90 initial investment (mount + case) and $40-50 for the next phone case as often as you upgrade...I think the smaller model Edge with trailforks integrated is the 530? Probably under $150 used with superior battery life and readability under the sun. And ofc thr gateway to start buying sensors for it :p
