‘Undo’ can be done by shaking your phone

I was confused by my iPhone asking me constantly if I want to undo typing. Turned out this was the device thinking I am shaking to undo.

Interesting. Do you find you have a shakier than usual phone grip?

I know that iPhones can alert the user when ambient noise levels exceed safety thresholds, and Apple Watches can detect and alert about detected falls, and even atrial fibrillation. I wouldn't be surprised if phone accelerometer signal processing could predict something like Parkinson's disease.

This thing triggers all the time on me when I do something like drop the phone on myself.

Is there a specific shake pattern? I use twist for camera and handshake chop for flashlight

I’d love a shake pattern for flashlight on iOS!

It's really handy, I don't generally even use the flashlight in my pocket when I have one on me, but somehow the phone gesture flashlight gets used about 10-20x daily, even for walking into a room without hitting the light switch, since the phone is in my hand.

Is this an iOS feature? Where do I find it?

Not that I know of.

Unfortunately the best flashlight gesture experience in the business seems to be sold by Motorola. At least last I checked.

My friend liked mine and even found an Android app for trying it on his phone, but basically it was 3x slower than the Moto gestures version despite being on a much faster phone. Not sure why.

I love how the ability to shake your phone to turn on the flashlight is practically gated by Motorola. God forbid we are able to do what we want with our phones. Gotta get vendor approval first.
