What kind of rollercoaster ride has more than ~10-20 g forces ?

I could see how "negative" g forces could lead to a false positive but I think the absolute forces are too low.

On the other hand I could see how during dancing the phone gets thrown around and that may be a similar pattern to a car crash.

I suppose that a regular crash but with a lucky ending can do a significant damage to phone in the pocket, because while the body is losing speed slowly, the phone and other things in pocket can hit the road hardly and ricochet with insane acceleration. I am a fan of downhill but I never carry my phone during that kind of ride when I am acknowledged about high chances of my crash. And in that risky kind of event I would rather go bombing the hill with a friend who can give me a proper help than rely on some computer.
