Ringer volume continues to reset to low

Check all these 3 settings (especially #3 a & b)

1. Silent switch (above volume up button) isn't in silent mode.

2. Settings → Do Not Disturb → Do Not Disturb = OFF

3. Settings → Sound & Haptics → RINGER AND ALERTS:

a. Slide Volume all the way to the right.

b. Change with Buttons = OFF

After extensive troubleshooting, the ringer volume problem happens whenever I connect my Plantronics Bluetooth headset. The ringer volume keeps changing (in my case to high volume). When I disconnect the Bluetooth headset the ringer volume behave normal. I tried AirPods and works fine with no issues so far.

Not sure if my Bluetooth headset is malfunctioning or it is a compatibility issue with iOS 13.1.2

My phone was doing same. Finally connected it to trips in car with phone connected via BT. No phone call in car required. When shut off engine and get out, ringer volume set very low. Happens ever car trip (does not happen any other time). Have to remember to manually reset ringer volume back up every time I get out of car. What a pain.

Nope, sorry to say it’s still doing it on my phone with 13.3.

As with others, it occurs after using car Bluetooth and switching off engine.

I have a car that is a few years old and maybe related to the Bluetooth version in the car stereo.

It doesn’t seem to happen with my newer Bluetooth audio devices (Sony headphones)

Same here. Volume changes when Plantronics Voyager 5200 is connected. In fact, just using the keyboard on the phone, the typing causes the volume to change. This only happens when the Bluetooth (BT) is connected, usually the volume goes up each time you press a key (letter, number, etc.). This has been going on since version 13, and still happening with 13.3. Have also verified the Plantronics device has the latest firmware update as of 12/29/2019.

Agree it is really irritating. Finding mine was related to BT in car, didn’t help me really...tried all the normal reboot/re-pair stuff, still no improvement.

Whether random, or related to BT in car, or something else, iOS 13 has introduced some very irritating unwanted ringer volume setting changes to many people.

Actually, some have also reported the ringer volume goes way up, to 100%, when they wanted it set low. In car and random. Don’t laugh, but I might just try setting it low, and see if after next car trip it goes up to 100% (and then stays there)!

I'm having the same problem but its going from low volume to max volume. I've noticed it most often after connecting it to my vehicles aux jack. This is a regression defect on Apple's part. I had this same issue in a long ago version of ios, but it evidently resolved until ios13 was released.

Hello,

Even with iOS 13.3 the problem persists. I did a lot of troubleshooting and seems there is a compatibility issue with Bluetooth v4.x and earlier devices. I contacted Apple Support multiple times but they are not willing to accept this as an Apple issue!!

Nope. The issue still persists. This happens when my vehicles Bluetooth connects. This is only on my iPhone 11 with 13.x - it was working fine pre-13 on my iPhone 6.

its also not just the ringer volume. My music plays big because the volume is 0 there’s no sound. So every time I get into the car and the phone connects the volume resets to 0 and I have to set it to the mid point. However even the. It somehow resets to another volume level wherever it feels like it. Very annoying. They should just use the software from before.

I tried disabling Keyboard Clicks, the issue still persists. The problem still there for any Bluetooth version 4.x and earlier devices. Apple Support doesn't seem to care much about this issue.

I use an Apple charging case and I think it is related to the connection to the case
