1. Make sure Hey Siri feature is enabled

Before moving forward, make sure the Hey Siri feature is enabled.

  • Step 1: Open Settings app on your iPhone, and tap Siri & Search.
  • Step 2: Make sure the option Listen for “Hey Siri” is enabled.
  • Step 3: If the feature is on, turn it off and turn it back on 30 seconds later.

2. Place your iPhone face up

When you place your iPhone face down, you might not be able to call out Siri by saying “Hey Siri” directly. To fix this issue, make sure that your iPhone screen is facing up. Alternatively, if you want to use Hey Siri feature then your iPhone is face down or covered, go to Settings > Accessibility > Siri and enable the Always Listen for “Hey Siri” option.


3. Restart your iPhone

A restart might fix most of software-related issues including minor symptoms after installing a firmware update, which is also a way to clear caches, refresh apps and system functions. Steps of different models vary, follow these steps to restart your iPhone.

  • For an iPhone X, 11, 12, 13, or later model: Press and hold either Volume button and the Side button until the power off slider appears. Drag the slider to turn it off.
  • For an iPhone 8, 7, SE or previous model: Press and hold the Power button until the power off slider appears. Drag the slider to turn it off.

After your iPhone is turned off, press and hold the Power button to turn it back on.


4. Check network connection on your iPhone

If your iPhone is disconnected from a stable network, then Hey Siri will not work too. Therefore, you can use the Airplane mode to refresh the network connection. Swipe up from the bottom of the screen and tap on the Airplane icon. After 30 seconds, turn it off. If it still doesn’t fix Hey Siri not working on iPhone, you can reset the network to factory settings by these steps:



  1. Open Settings app on your iPhone.
  2. Go to General > Reset, and tap Reset Network Settings.
  3. If asked, enter the passcode of your lock screen to proceed.
  4. Once the reset is done, reconnect your iPhone to a stable network to fix Hey Siri not working on iPhone.

5. Change your Siri’s voice and language

If your iPhone was purchased from another region, then Siri defaults to the language from that region. Therefore, you need to reset the Siri’s language.

  • Step 1: Go to Settings > Siri & Search > Language.
  • Step 2: Choose the language and dialect that is right for you from the list.
  • Step 3: Restart your iPhone and Hey Siri should work fine.

6. Check Siri app restriction

If you accidentally restricted Siri’s microphone access, then the Hey Siri feature might not work properly. Or, if you recently updated your iPhone, the permissions might be overridden. Follow the steps below to open permissions for Siri.



  1. Open Settings app on your iPhone.
  2. Go to Screen Time > Content & Privacy Restrictions.
  3. Select Siri and disable the restriction of microphone.

7. Check Voice Feedback feature

If your iPhone is on silent, Siri will not work properly. And the same thing happens when you turn off the Voice Feedback feature. This feature is available after an iOS 13 update. If you recently update your iPhone to iOS 13 or above, check the Voice Feedback feature by following the path below.

  • Step 1: Go to Settings > Siri & Search.
  • Step 2: Tap on Voice Feedback, and select Always On.

8. Turn off Low Power Mode

If you have enabled Low Power Mode, and your iPhone is on extremely low battery, then this feature may limit Hey Siri. In this case, you can charge your iPhone for a while, and when the power reaches to a certain percentage, Hey Siri will start to work again. Or, you can turn off the Low Power Mode by going to Settings > Battery and tapping off Low Power Mode option.


9. Check your iPhone microphone

Over time, iPhone microphones can struggle to function with exposure to dust, lint, and other debris. You can clean the microphones with a toothbrush, cleaning kit, or any makeshift tool. Alternatively, if your iPhone microphones are blocked by something like the case, remove the case to let microphone work again.


10. Update your iPhone to the latest iOS system

Every iOS system update usually comes with bug fixes. If Hey Siri not working happens after you updated your iPhone, you can wait for the latest iOS system update to fix this issue.



  1. Open Settings app on your iPhone.
  2. Tap General > Software Update > Download & Install to download and install the latest version of iOS system.
  3. If it says Install Now instead, tap on it to start updating your iPhone to the latest iOS system.

11. Force restart your iPhone

If a normal restart doesn’t help you fix Hey Siri not working issue, then you can try to perform a force restart. Force restarting your device will deliberately cut off the power from your phone’s battery to its hardware, so it is more thoroughly. As with a normal restart, the steps of force restart vary from different iPhone models.

  • For an iPhone 8, X, 11, 12, 13 or later model: Press and quickly release the Volume Up button, press and quickly release the Volume Down button, then press and hold the side button until Apple logo appears.
