Volume Slider stuck at 100%

I have the same problem bu the solutions here didnt help at all

Try and Force Restart your iPhone EXACTLY as shown below and see whether that resolves the issue:

• Press and quickly release Volume UP button
• Press and quickly release Volume DOWN button
• Press and Hold the SIDE button until an Apple logo appears and then release the Side button (Can take up to 20 seconds. (DO NOT release Side Button when invited to Slide Power OFF).

⚠️ I had the same problem but I FIXED IT ⚠️

1. Go to control centre and see if any music is “playing” (you won’t hear it, it will just say it’s playing)
2. Hold down on it and press the airplay logo
3. Check what it says eg.

Mine said “Dock Connector” and it turns out if you’re charging your phone in a car it thinks the usb port is a speaker. If you take out the cable it will sort it.

Hope this helps! 😁

Turned phone on and off again and its fixed itself.

Thanks so much, it works!

Did this and it worked for about 3 seconds before the problem persisted. Very strange.

Oh my gosh thank you so much I am on a 10 hour road trip and I was charging my phone with a cable in my car 😭 I was so confused why my volume wouldn’t lower
