Make Sure You're Holding Your iPhone The Right Distance From Your Face

Face ID is designed to work when you hold your iPhone about 10-20 inches away from your face. If Face ID is not working on your iPhone, you may be holding it too close or too far away from your face.

  1. Hold your arms straight out in front of you to make sure it's far enough away from your face.
  2. You may need to close and reopen the Settings app if Face ID failed the first couple of times.

Clean Your iPhone's Cameras And Sensors

If Face ID is not working on your iPhone, there may be gunk or debris obstructing one of the cameras or sensors on your iPhone.

  1. Using a microfiber cloth, gently wipe the front of your iPhone.
  2. The cameras and sensors are located near the top of the iPhone.

Check Your Surrounding Conditions

Face ID may not work on your iPhone if it is too bright or too dark behind you. Face ID may also fail if there are other people in view of the cameras and sensors on the front of your iPhone.

For Lighting:

  1. Make sure the sun is not directly behind you when trying to use Face ID. The sun's brightness can throw off your iPhone's sensors and cameras.
  2. Make sure you're in a well-lit area. Your iPhone may struggle to recognize your face if it's too dark.
  3. For consistent results, use Face ID in area that's well-lit by natural light.

For Other People:

  1. Make sure there are no people standing behind you when using Face ID.
  2. If you're in a busy area like a city, try to find a private place to use Face ID. People constantly walking behind you may throw off your iPhone's camera and sensors.

Erase Your Saved Face ID & Set It Up Again

If something went wrong the first time you set up Face ID on your iPhone, you may not be able to use facial recognition successfully. Think of this step like forgetting a Wi-Fi network your iPhone isn't connecting to.

  1. Open the Settings app.
  2. Tap Face ID & Passcode.
  3. Enter your passcode if one is set up.
  4. Tap on the face you want to delete.
  5. Tap Delete Face.
  6. Once the face has been deleted, enroll a new face and try again.

Reset All Settings

Many iPhone problems are caused when Settings isn't set up correctly or by corruption within individual Settings app files. Restoring the Settings app back to factory defaults doesn't fix every iPhone software problem, but it is a go-to fix for Apple technicians because it does solve a lot of problems that would be very difficult to to track down by hand.

  1. Open the Settings app.
  2. Tap General.
  3. Scroll down and tap Transfer Or Reset iPhone.
  4. Tap Reset.
  5. Tap Reset All Settings.
  6. Enter your passcode, if prompted.
  7. Tap Reset All Settings again to confirm your decision.
  8. Your iPhone will shut down, complete the reset, and turn itself on again will automatically turn back on when the reset finishes.

DFU Restore Your iPhone

A DFU restore has the potential to fix software problems by completely erasing the code which may be causing your problem. The code is rewritten as if your iPhone is brand new, so the software problem may get solved.

Think of it like a house that has cracks in the foundation. Rather than try and fix the cracks, we are building an entirely new foundation.

If you can, back up your iPhone before completing a DFU restore. Any time you do a restore, it erases everything from your iPhone. However, after the restore is completed, you restore all your backed up data back onto your iPhone.

Repair Your iPhone With Apple

Apple repairs iPhones at the Genius Bar in Apple Stores and through their online mail-in repair service. Apple repairs are high-quality, but out-of-warranty repairs can be much more expensive than third-party solutions. If you're looking to save some money you're not covered by Apple's warranty, you may want to check out our other recommendations.

How Do I Repair My iPhone With Apple?

How To Repair Your iPhone With Apple's Mail-In Service

  1. Visit Apple's support website to begin the online mail-in repair process.
  2. Alternatively, call 1-800-MY-APPLE (1-800-692-7753) to set up a repair.

How To Repair Your iPhone At The Genius Bar Inside Your Local Apple Store

  1. Visit Apple's website to make a Genius Bar appointment before you go into the store. Apple Stores are extremely busy, and if you don't have an appointment, you may have to wait for hours or end up being turned away. (Editor's note: I'm a former Apple tech and we're not exaggerating — please, do yourself a favor and make an appointment first!)
  2. When you arrive, go to the Genius Bar to check in for your appointment.
  3. Genius Bar appointments always include free diagnosis. If you're under warranty, many repairs can be done on the spot, but it all depends upon which parts are in stock. If you're not under warranty, the Genius will give you a quote for the cost of a repair.
