Ios26 and now even Ios27 have this weird audio stream merging bug.
Say you keep your ringtone volume to max(which usually most of us do) and lower the media volume, say you’re in public watching a media in silence.
what happens now is, when you receive a call your media vol switches and matches the ringtone volume, which literally means blasting out your media content in public abruptly.
Issue is see. with/without earphones on ios27, well in ios26 keeping phone in silent didn’t switch media volume to ringtone volume, but ios27 made this bug even worse.
its really embarrassing and annoying that apple hasn’t patched this bug yet and its such a ‘everyday usecase bug’.
Switching of audio stream i believe isn’t a feature, it’s definitely a very very annoying bug.
I was able to reproduce this on 17 pro max and 17 as well.
