ios "14" audio button flickers during call.
The audio button flickers during calls. But also disable the screen so I’m unable to click on click mute. Currently on the latest version of iOS 14.4 (18D52) and using a iPhone 12 pro. The issue has been happening for months. Happy to forward screen recording of the issue happening.
Hi bveseli,
Welcome to Apple Support Communities! We appreciate you reaching out about this issue while in a phone call, and would love to help sort it out.
To start, let us know more about what's going on. Does the button flicker in every call? Have you had a chance to restart your iPhone since noticing this behavior?
Do you have any Bluetooth audio devices paired with your iPhone. If so, head into Settings > Bluetooth, disconnect those devices, then place a test call to see if the issue remains.
If the issue persists, let's investigate further. Do you have any AirPlay devices nearby that can be used for audio during a call? If so, go to Settings > Phone > Calls on Other Devices, and turn off the option for Allow Calls on Other Devices, then test again.
We're here for you if you've got any questions.
Have a great day!
