From a cellphone’s perspective a crash = extreme acceleration with different vectors vs a dropped phone, they can also listen for broken glass etc. So even with GPS off that’s detectable.

Interesting info/link, thanks for sharing.

Generally I read your comment that a dropped phone only hits the floor once, therefore there is only one vector and the car always overturns/flips/turns and therefore there are multiple vectors measurable in the car?

I am not convinced yet, it might be possible without GPS, at least to some degree of error (false positives and false negatives). The info in the link requires GPS to be switched on. hmm
