Has anyone noticed that while listening to music, or other types of audio, the volume of VoiceOver is the same volume level as the music? Normally, the audio, like music will turn down, while VoiceOver is talking, then after it's done talking, the audio volume will turn up again, but in iOS 8, it doesn't. Instead, VoiceOver will talk, and the volume of the audio will still be loud, and you can't hear what VoiceOver is saying. I've emailed the accessibility team about this issue, and got the usual response of Thank you for your feedback. We've forwarded this to the correct department.
P.s... In order to get things working normally, should anyone experience this issue, press and hold the sleep/wake button, and home button. This will reset the phone. No media or data will be eiraced.
