iOS 16.4 Is A Killer Update — Five Amazing Features!

I’m sad the RC is out already. I needed more of such amazing features.

#1. Voice Isolation arrives to cellular calls 📞

Voice Isolation, if turned on, prioritises your voice in a call, filtering out the surrounding ambient noise — so the other person would hear you clearer.

Until now, this was offered only for FaceTime and other internet-based calls (like WhatsApp, Zoom, Teams). But with iOS 16.4, it arrives to normal cellular calls too!

To use it, while on your first iOS 16.4 cellular call, open Control Center, tap Mic Mode, select Voice Isolation.

It’s a one-off process — so all your next cellular calls will have Voice Isolation enabled.

Let it be so.
Nothing to lose. Everything to gain.

Also, if you’ve observed it, the image says ‘Wide Spectrum is currently unavailable”.

It’s a mode that enhances all the background noise, suitable when a group of people physically sit nearby and talk to someone on a call. So the iPhone won’t mistake the voice of distant people as background noise.
