please add crash detection in XR models

The XR does not have the necessary internals so you won’t ever have this feature on that device. You would need to upgrade. This is no different than most technology when a newer feature is implemented. Older devices are not usually forward compatible (otherwise why would anyone ever upgrade to new tech if their older tech will do anything new that comes along) with “major” new features. It’s not in any tech providers best interest to continuously make all new advancements backwards compatible nor is it realistically possible

The hardware of your XR would have to be completely redesigned in order to add crash detection.

Crash detection cannot be added simply by using software. You have to have the hardware in place first.
