Action Button function on iPhone 16

I have strange behavior while using the Action Button on iPhone 16. It should be working with just long press to activate configured function. But when the phone turned off, I have to press the button and then press and hold it again to activate the function. Is it normal? I found out it problem the most obvious, when the button is configured to start the Torch

iPhone 16, iOS 26

Action Button doesn't activate the shortcut sometimes Hi everyone, I've assigned the Action Button to open the "Set Timer" shortcut. I set this up by going to Action Button in Settings, selecting Shortcut, and choosing "Set Timer" from the "Get Started" section. It usually works well, and this is how it looks like https://ibb.co/C9t5dLd However, occasionally the shortcut doesn't activate when I press the Action Button. The shortcut icon appears in the Dynamic Island, but nothing else happens. Here is how it looks like when this bug happens: https://ibb.co/YkRnvnM Restarting my phone or locking/unlocking it usually resolves the issue, but it's quite annoying having to deal with this. It happens at least 3-4 times a day depending on how often I use the timer. Has anyone else encountered this? I'm using an iPhone 15 Pro running iOS 18.2. Thanks for any help!

Unable to choose any options in iPhone 15 Pro Max Settings app running iOS 18.4 iPhone 15 Pro Max, running iOS 18.4, restarted several times, will not use any of the options that I choose in "Settings > Action Button". The button works fine in all other respects: will lock screen with single short press, will summon Siri if set to do so in "Settings > Accessibility > Side Button". But I can't use magnifier, can't select a shortcut, etc etc. I want to set it so that I can talk to Perplexity instead of talking to Siri. [Re-Titled by Moderator]
