There can be several reasons why Siri is not working on iOS 16. It’s possible that a previous update bricked the AI tool, or there are issues with your configurations. 

Besides, temporary errors, corrupted data, and third-party apps can also prevent Siri from working. 

To help with the issue, we’ll show you what to do if Siri is not working on your iPhone. 

Let’s begin!

1. Restart Your iPhone. 

Before tweaking your settings, try restarting your iPhone first. A temporary bug or glitch may have caused Siri to run into errors. 

Restarting your device should clear corrupted data from the system memory, eliminating any issues that occurred on your system during use. 

If you are using an iPhone X, 11, 12, 13, 14, or later, here’s what you need to do: 

  1. Hold down the Volume Down button and Side button until the ‘Slide to Power Off’ prompt appears. 
  2. Now, drag the slider to the right and wait for 30 seconds. 
  3. Press the Side button afterward to turn on your device.

  3. Enable Listen for “Hey Siri” and Press Side Button for Siri

  2. Go to General > Keyboard
  3. Look for Enable Dictation and tap the toggle switch beside it.

  2. Wait for 5 to 10 seconds.
