Download Hearing Saver

Set the "Volume to set when headphone jack is plugged:" to a little above that threshold where it gives you that warning.

Now when you plug in your headphones or in most people's cases an auxiliary cable for your car, it will throw that message right away. It will not throw the message again until you reboot your phone.

This is not a perfect solution but it does at least get rid of the warning from happening when you are in the middle of driving or something and want to just turn up the volume a little.

To me, the single biggest thing is lack of customization/choice throughout iOS. It's Apple's way or the highway. A lot of the time, I like Apple's way! I have a MBP and a huge music library that I still manage through iTunes so I love how easy the synching process is.

But, for example, I hate that I can't rearrange the icons on the home screen. I'd prefer to have no icons at all on the top row or two, maybe a widget if that were available (had a weather one on my last Android phone). I don't need or want an almost completely full home page of apps, but I also DO want to have my most frequently used apps as far down on the screen as possible because I have a 7+ and small hands.

I'd also like to have much more control over volume control. my basic situation boils down to 3 main ways I listen to my phone other than speakers: car speakers, over the ear headphones, airpods. My car stereo sucks/is quiet so I need to have the volume 80%+ for that, while 80%+ with my headphones can literally probably cause hearing damage. On Android I could just download and install Hearing Saver but I haven't been able to figure out anything similar on iOS yet.

I could go on but that sort of stuff makes up probably 80% of my problems with iOS/iPhones in general. still love my phone!

Commented below, but here it is again: "Hearing Saver" app will override this. Set your settings to max when headphones are plugged in, and stop getting the pop up message. https://play.google.com/store/apps/details?id=com.jakebasile.android.hearingsaver&hl=en

You need root access and wanam xposed. No other way AFAIK

edit: There is an app on the play store called 'Hearing saver' that won't disable the notification but bypass it. Seems to have worked for some folks: https://play.google.com/store/apps/details?id=com.jakebasile.android.hearingsaver&hl=en

It will prompt you once, and then it will never ask you again until you restart your phone.

i installed this recently and it's awesome for any bluetooth or aux jack use. automatically maxes volume and bypasses the warning.

i have this same issue, and found this in the play store.

I haven't field tested it yet, but its got good reviews and claims to fix this. Worth a shot, I guess.

I used to have an app called Hearing Saver and it did the trick, sorta. It made it so when you plug in a headphone jack it defaults to the highest, skipping the warning. Then I could adjusted freely as needed.

I installed this app: Hearing Saver

which you can tell to set your volume to pre-defined levels (100% in my case) when headphones are plugged in or, in my case, when bluetooth audio is connected. Works most of the time but still not every time. Used it on my Note 4 and now my S7E.

Try Hearing Saver. I use it to max the volume when I connect to BT and turn it all the way down with I disconnect.

It can probably do what you're looking for.

I've been using Hearing Saver for this exact thing (bluetooth). And it also turns the volume back down ^so ^I ^don't ^get ^busted ^watching ^porn ^at ^work.

Works great but you have to open the app and click enable whenever you restart your phone (nbdimo). May be a good option for you since you're not into Tasker.

Galaxy S6 Edge+:

The power button is in the worst possible place. If you hold it, and try to adjust the volume, you're more likely to turn it off. Put it on the top.
Why can't anyone make a phone dialer that shows ALL of the buttons (mute, bluetooth, speaker, etc) AND the contact/number at the same time? Why do I have to fucking toggle? There's enough space!
The stupid launcher which I always replace, along with disabling all your bloatware.
Why no front-facing stereo speakers? Is this 1970?
A fucking volume warning? (Gone thanks to Hearing Saver though.)

Otherwise, I love my phone. Really, I do.

There is also an app that does it:

The only gotcha is that if you restart your phone you have to click Ok once more, but then it's good.

Hijacking the top comment to recommend you install this app:

https://play.google.com/store/apps/details?id=com.jakebasile.android.hearingsaver&hl=en_US

It requires you to click OK once, and after that it is disabled until you restart your phone.

Install this:

https://play.google.com/store/apps/details?id=com.jakebasile.android.hearingsaver&hl=en_US

You will have to do it once, or after you restart your phone. Never again after that!

I do not have the perfect answer but perhaps until you can re-enable it one of these will help. Hearing Saver apps

Peace & Prayers

yes, download the Hearing Saver App

you can set it to remember certain volume level setting for bluetooth devices etc, but a corollary feature is that it bypasses the "volume too loud" message box. Unfortunately you have to initiate the app after each restart, but a majority of people are not restarting their phone that often.

Yes, there is.

Download the app Hearing Saver, install and set the "Volume to set when headphone jack is plugged" slider to full.

I think you set it once and that's it. You have to check for Bluetooth detection.

It has no permissions: hearing saver

Looking around on the interweb I've found a couple of mentions of Hearing Saver. I've not had chance to try it yet, but I have it installed and I'll be going out in the car later.

I'll report back.

I connect my phone to a set of speakers, but Android thinks I'm putting headphones in and it turns the volume down.

Hearing Saver lets you decide what volume you'll get when you connect and disconnect from the headphone jack. Just be careful if you actually use headphones sometimes.
