With the removal of the headphone jack, phones have lost the ability to not know what is plugged in. USB and Bluetooth devices have information that the phone could account for but chooses not to.

My phone warns me I've been listening to music at a dangerous volume for a dangerous amount of time 100% of the time when I'm driving and listening via aux.

yeah lol, I'm often plugging in slightly high impedance headphones that it just can't drive very well. it's never seemed worth it run run a dac or get a special pair of phone headphones. i rarely use it that way anyway.

but yeah, pretty much every time i plug them in i have to confirm i want to hurt myself before it will allow them to be set to a useable volume.

and yes, i do still have a headphone jack, they are still out there if you're willing to not get a super expensive phone.

I really hate that “no one:” shit, it often doesn’t make any sense to me.

your phone doesnt change it back when you disconnect Bluetooth? that's harsh.

Mine warn me only when it's purposeful. As you say, if I change output devices, and the sound is too loud, it says nothing. It literally only interferes with me doing something I'm purposefully choosing to do, and failing to protect me from shit I'm doing accidentally.

This is the real issue. The same volume is totally different on different devices. If they want to implement this feature correctly they need to measure the actual output of the headphones.

Copied from other comment:

There's an app for that: https://github.com/zacharee/Tweaker

You'll need to use adb to grant special permissions that an app can't request on its own.

adb shell pm grant com.zacharee1.systemuituner android.permission.WRITE_SECURE_SETTINGS
adb shell pm grant com.zacharee1.systemuituner android.permission.PACKAGE_USAGE_STATS
adb shell pm grant com.zacharee1.systemuituner android.permission.DUMP

• Audio & Sound --> Disable Safe Audio Warning --> Disabled
• Persist Options --> Checkbox Disable Safe Audio Warning

Ideally disable all the nanny features and block forced updates. If I fucking want an update, I will prompt it myself.

I think it's a legal thing so they're probably not allowed to get rid of it.

Shit even with headphones, I don't need this crap because I ain't using some POS headphones without their own volume control.

If you're connected to a device that has independent volume management, then you can max out the phone volume and still have it be too quiet.

I most often run into this with my speaker setup in my workout room if I forget to turn up the volume on the receiver before hopping on the treadmill.

But, the other reason to not go too high is the audio can start degrading if the volume is too high on your phone.

You're dependent upon the recording you're listening to having been set to a decent volume to begin with. I will occasionally come across videos or music with significantly quieter sound than usual. I know what a good volume for my need at the moment is, while this warning is a dumb automatic pop-up based solely upon the single factor of the master device volume control setting - without any consideration for the actual decibels being output.

What are you using that does that? That's annoying af.
