Still don't get the point of 5G. In my experience a high-quality LTE deployment is plenty and I never felt like 5G was that fast (only ever used it in UAE).

Don't have 5G back home and don't want it, LTE serves me plenty well with 30-50mbps speeds and unlimited internet plans for ~7usd pcm.

It certainly serves no purpose in countries like UAE, USA and Canada, because you don't get enough allowance to take advantage of the high speeds..

You don’t need the direction however, just the magnitude of the acceleration in 3D prior to impact. If it is within the ballpark of 9.8 m/s prior to the massive impulse spike caused by it hitting the ground you can disregard the spike as a drop. If the phone is at a resting state/a state with very little acceleration prior to impact (ie a phone on a dash in a car that immediately hits a wall) or has a large magnitude of deceleration (driver hits the breaks quickly before impact) than you can diagnose that as a crash. You don’t need direction of acceleration if you just simplify the problem

Geofence is not the correct solution to this problem. It’s a bandaid to handle one failure case when the underlying system is broken. What happens when there’s a standalone roller coaster that isn’t in an amusement park? What happens when you crash your car on the outskirts of an amusement park?

Crash detection shouldn’t be going off for anything but a car crash. If you have to think about geofencing areas where phones are experiencing unusual forces, something is wrong with the feature.

Programmers don’t “think them through”. The people responsible for thinking things through is a product manager.

The thing you’re complaining about with Reddit, also a product manager and UX designer. Devs just code what they say.

Yeah there was a news release I saw the other day about the significant increase to abandoned 911 calls from accidental calls from those types of features. This article was from the Guelph Police in Ontario and the police service recommended people disable this feature because of the impact it was having on 911 dispatch.

smoke detectors do something similiar(at least Photoelectric smoke alarms do) when they first detect smoke(by the lightbeam being interupted/scatterd and thus the current changing on the sensor) they send out a couple more light flashes in quick sucession(they usualy send a beam every so often(i think it was every second or 5 seconds? anyway, not constantly)to check if the disturbance was just a dust particle or actual smoke THEN it rings the alarm....

​

not hard to implement something similiar into this i imagine.
