alt Hacker NewsA Moto phone with GrapheneOS and the "chop / chop" gesture[0] to turn on the flashlight would be a dream.
I'm, shamefully, an adherent to Moto hardware now because of that silly gesture. I use it multiple times a day. I had a friend with a late model Pixel try to replicate the functionality and he couldn't come up with a way to do it. It's silly, but it's too handy.

The chop chop gesture is amazing. I love my G3 unfortunately it stopped recieving updates :( some apps are starting to get funky in weird ways

Neat. I wired the flashlight to a long press of the Bixby button on my S10+.

One of the important reasons that it works so well is because it uses the Hexagon DSP in the Snapdragon processors to catch the events. That's why it's so hard to replicate. It's possible to do it entirely in software, but it chews through battery if you do it that way. I can't find it now, but there was an article a few years ago that explained how the feature worked.
And there's no way to program the DSP without being the creator of the device because Qualcomm requires DSP programs to be signed, as far as I'm aware, and the key has to be trusted by the device vendor.
