If you’re struggling to unlock your iPhone with Face ID because you’re wearing sunglasses, there’s a simple trick you can use to skip Face ID and go straight to entering your PIN.
Just swipe up on the screen and tap on the “Face ID” text in the middle of the screen. This will switch you straight to the PIN entry screen.
If you tap elsewhere on the screen, it won’t work. But by tapping directly on the Face ID text, it’ll switch straight to pin entry.
This trick is a great way to save time and frustration when you’re trying to unlock your iPhone while wearing sunglasses.
Another trick worth knowing is Face ID’s Alternative Appearance setting. This setting allows you to teach Face ID to recognize you with a different appearance, such as when you’re wearing sunglasses.
To set up an alternate appearance, go to Settings > Face ID & Passcode > Set Up an Alternate Appearance.
Once you’ve set up an alternate appearance, you’ll be able to unlock your iPhone using Face ID even when you’re wearing sunglasses.
If you’re still having trouble unlocking your iPhone with Face ID, you can always use your PIN as a backup.
Here are the steps your phone takes when using Face ID:
1. The TrueDepth camera system projects over 30,000 infrared dots onto your face.
2. The infrared camera captures an image of your face and sends it to the Secure Enclave in the A12 Bionic chip.
3. The Secure Enclave uses machine learning algorithms to compare the image of your face to the enrolled face data.
4. If the image of your face matches the enrolled face data, the Secure Enclave sends a signal to the operating system to unlock your iPhone.
Face ID is a very secure facial recognition system. It’s designed to protect your iPhone from unauthorized access. Even if someone has your iPhone, they won’t be able to unlock it with Face ID unless they know your passcode.
