If you’ve ever hit the mute button during a FaceTime call and then quietly muttered something under your breath, thinking no one could hear you, bad news. You might still have been on mic.
In a quiet but important tweak, Apple just rolled out iOS 18.5 with a fix for a surprising FaceTime bug.
Apparently, when users tried to mute themselves during a FaceTime call, the app didn’t always follow through. In other words, people thought they were muted, but their microphones were still picking up everything.
Yes, it’s as bad as it sounds. This wasn’t just a minor glitch—it was a potential privacy headache.

Think about how often we hit that mute button during work calls, family chats, or awkward conversations. Now, imagine everything you said in those “muted” moments might have been heard loud and clear on the other end.
This bug didn’t affect everyone, but it was real enough that Apple patched it quickly in iOS 18.5. The update notes don’t go into great detail, but they confirm the issue: the microphone didn’t always mute as expected during FaceTime calls.
It’s a good reminder that sometimes, our devices don’t behave exactly as we assume. We trust that when a button says “mute,” it means “no one can hear me.” But in this case, that trust was slightly misplaced.
So, what should you do? First, update your iPhone to iOS 18.5 if you haven’t already to keep your conversations safe and secure.
And if you’re the kind of person who assumes mute means safe to vent or whisper something off-the-record, maybe double-check that your mic icon is really off before speaking freely.
Apple didn’t say how long the bug had been around, but the fix is live now. It’s better late than never.
