I’m fairly sure this is a Beta firmware thing, but LIFX for iOS v3.14.0 (via TestFlight) just upgraded my Tile to firmware
3.50-TILE and now the touch sensitivity is working. Mostly. Here’s a video of it in action:
I still have to play with with the sensitivity slider because it seems to miss taps or thinks a double tap is a single. Also, doesn’t appear to expose any HomeKit actions which is disappointing, but hopefully something that can be added later. Would be amazing for a single or double tap to appear as a HomeKit switch.
Added bonus: a new firmware effect called Fire which does exactly what you think it would.
