- Solution 5: Fix Touch ID without Data Loss
- Solution 6: Apple Support
1. Clean Both Finger and Home Button
When you see iPhone saying unable to activate Touch ID, it is not necessarily the iPhone that is problematic. Some users might have the habit to unlock the Touch ID with their fingers covered with water, dust or other things, which will prevent the phone from recognizing users' fingerprint. The same thing happens when the finger reader is dirty.
Another culprit is the Home button protector, which some people apply on their iPhone to prevent damages. From our personal experiences, this may hinder the usage of Touch ID. Therefore, what we need to do is to clean up our fingers and the Home button and remove all protection from the Home button.
2. Enable All Touch ID Settings
Touch ID is used in several different scenarios, and each of them needs to be specifically turned on to be used. Sometimes certain Touch ID options are turned off and cannot be used in that specific scenario. To make your Touch ID goes back to normal, you need to follow the steps below to turn those options back on.
Step 1: Go to "Settings" > "Touch ID & Passcode" and toggle off all the options in the menu;
Step 2: Restart your iPhone;
Step 3: Go to "Settings" > "Touch ID & Passcode" and turn on all the options you just disabled.
3. Delete and Add Fingerprint Again When Unable to Activate Touch ID
Just like what we do when your Face ID not working, you can delete the old fingerprint and add a new one when you are not able to activate Touch ID on iPhone, which can renew the recognition of the Touch ID. Besides, the more fingerprints enrolled, the more difficult it is for iPhone to identify your Touch ID. Therefore, it is recommended to enroll no more than 3 fingerprints.
Step 1: Go to "Settings" > "Touch ID & Passcode", scroll down to the list of fingerprints;
Step 2: Tap on each fingerprint and then click the Delete Fingerprint option to delete the fingerprint. Delete all the fingerprints;
Step 3: Reboot your iPhone and add a new fingerprint.
4. Use the Touch ID Properly
Some users are used to unlock the Touch ID in strange ways that it almost becomes hard for them to abandon the habit. Silly as it is, even some of our technicians fall for this. When using Touch ID, your finger is supposed to cover the Home button completely, touching the surrounding metal ring. Most importantly, you shouldn't tap too quickly, press the Home button too hard or move your finger around while the phone is still scanning your fingerprint.
