Restarting your iPhone is the quickest way to fix minor issues, including Face ID. Clean the front camera cluster to remove dirt or fingerprints that could interfere with facial scanning.
If your appearance changes, add an alternate face in Face ID settings. Reset Face ID and set it up again if it still doesn't work.
Make sure Face ID is turned on for functions like unlocking and Apple Pay payments. Try turning “Require Attention” off/on again to increase recognition accuracy. Don't forget to update to the latest iOS as Apple often fixes bugs and optimizes Face ID performance.
After performing the above steps, Face ID will work stably again as before. Readers are invited to watch more videos : Iris scanning tool to verify human identity | VTV24
