How To Fix "Hey Siri" Not Working on iPhone 16 Pro Max

Select Language:

If you’re having trouble with “Hey Siri” not working on your iPhone 16 Pro Max running iOS 26.0.1, but it works fine on your iPad Pro with the same iOS version, don’t worry—you’re not alone. Sometimes, even when everything seems set up correctly, Siri can be a bit stubborn. Here’s a simple step-by-step guide to help you troubleshoot and hopefully fix the issue.

First, double-check that “Hey Siri” is turned on. Go to Settings > Siri & Search, then make sure the toggle for “Listen for ‘Hey Siri'” is enabled. Turn it off and on again to refresh the setting.

Next, try restarting your iPhone. Sometimes, a simple restart can resolve temporary glitches. Press and hold the side button with either volume button, then slide to power off. Once it’s off, hold the side button again until the Apple logo appears.

If that doesn’t work, do a hard reboot. For the iPhone 16 Pro Max, quickly press and release the volume up button, then do the same with the volume down button. After that, press and hold the side button until the Apple logo appears.

You can also compare the settings between your iPhone and iPad. Make sure that Siri & Search settings are consistent on both devices. Sometimes, small differences can interfere with functionality.

If needed, reset your iPhone’s settings. Go to Settings > General > Reset > Reset All Settings. This won’t delete your apps or data but will reset system settings to default. After doing this, set up “Hey Siri” again.

If none of these steps work, consider updating your iPhone to the latest software version if available. Sometimes, bugs that cause these issues are fixed in updates.

Hopefully, one of these solutions will get “Hey Siri” working on your iPhone 16 Pro Max again. If not, reaching out to Apple Support might be the next best step.
