WhatsApp's New iOS Call Shortcut Exposes a Mic Mode Apple Buried in Control Center for Years

Apple built Voice Isolation and Wide Spectrum into iOS 15 in 2021, hid them behind a Control Center swipe and two taps, and most iPhone owners never found them. WhatsApp's latest App Store update puts all four mic modes one tap away on the call screen, and the setting sticks between calls. It's the only new thing on the iOS beat today: no Apple build since July 13, with iOS 27 beta 4 expected around July 20 and the iOS 26.6 release candidate likely the week after.

WhatsApp surfaces Apple's mic modes inside its call screen

9to5Mac (Marcus Mendes, July 16) and WABetaInfo (July 15) both confirmed this week that WhatsApp version 26.27.74, available on the App Store, is rolling out in-call mic mode controls to some iPhone users now, with the rollout continuing over the coming weeks.

Here is what actually changed. During a WhatsApp voice or video call, you can now tap the "More" button at the bottom of the call screen and select "mic mode" to open Apple's system-level audio menu without leaving the call. iOS applies the mode immediately, no interruption. The four options are the same ones Apple has offered system-wide since 2021:

• Standard: default audio processing, no filtering.
• Voice Isolation: prioritizes your voice and suppresses background noise. The one most people actually want.
• Wide Spectrum: leaves ambient sound unfiltered, useful when you want the other person to hear your surroundings.
• Automatic (requires iOS 18): iOS picks the best mode on the fly, switching to Voice Isolation for earpiece calls and Standard for speakerphone.

WABetaInfo notes that once you pick a mode, it persists across future WhatsApp calls until you change it. Turn on Voice Isolation once and every WhatsApp call after that uses it automatically.

The hardware and software gates track Apple's own rules: Voice Isolation and Wide Spectrum need iOS 15 or later and work on the iPhone XR, XS, and newer. Automatic mode needs iOS 18 or later (9to5Mac, July 16).

One detail worth knowing: WhatsApp did not build its own noise cancellation engine for iOS. On Android, WhatsApp shipped a custom noise-reduction feature that runs inside the app. On iPhone, WhatsApp is simply exposing Apple's existing system mic modes in a more convenient spot. The audio processing is all Apple's. WhatsApp just made it findable (WABetaInfo, July 15).

That convenience is the real story. Apple introduced mic modes in iOS 15 alongside FaceTime, later extended Voice Isolation to regular cellular calls in iOS 16.4, and added the Automatic mode in iOS 18. But to reach them, you had to swipe into Control Center, find the audio module for the active app, and tap through to the mic mode picker. WABetaInfo's read is blunt: most people never did all that mid-call, so a lot of iPhone users will discover the feature exists for the first time because WhatsApp put the shortcut where they can actually see it.

If the mic mode option does not appear yet, update WhatsApp to 26.27.74 from the App Store and wait. WhatsApp is rolling this out gradually and has not said when everyone will get it.

Tracking: no new Apple build, and what comes next

Apple has not shipped a new iOS build since July 13, when both the iOS 27 public beta 1 and iOS 26.6 beta 5 landed the same day. The developer releases page still shows July 13 as the latest iOS entry. The only Apple release since then was an App Store Connect API update on July 15, which is not user-facing.

Two things to watch, both consistent with yesterday's 48-hour reality check:

• iOS 27 beta 4: Aaron Zollo expects the next developer beta around July 20, with the second public beta landing in the same window. If you are on the public beta and hitting the CarPlay Siri bug or AirDrop sending failure, that is the build that should address them. The stability picture from day 3 is unchanged: fine on a spare phone, hold off on your primary if you depend on banking, hearing-aid, or point-of-sale apps that are still broken.
• iOS 26.6: beta 5 shipped July 13 with no new features, just bug fixes and security. The release candidate is expected the week of July 20, with the final public release around July 27 based on Apple's historical x.6 cadence (iOS 18.6 and 17.6 both shipped July 29 of their respective years). Stay on iOS 26.5.2 until then.
