"My TouchID is not working after iOS 10 uodate. Doesn't work to unlock the phone, nor apps that use it. I disabled/enabled it. Re-setup my fingerprints, and no luck. Rebooting phone doesn't help either." confirms a user at the Apple Support forum.
Touch ID is a way you can secure your iPhone as you might be using Apple Pay purchases in stores or within apps. But what if your Touch ID is not working on your iPhone 7 or iPhone 7 Plus? In this article, we will give you an easy solution to unlock Touch ID fingerprint sensor.
Before we provide you any solution to your Touch ID problem, just imagine what makes your Touch ID fail or when Touch ID fails to work.
One of the first mistakes happens when you calibrate the fingerprint. Even though the iPhone 6 or 6 Plus sends you a message that your finger has been calibrated successfully, there are some chances that the calibration is not done perfectly.
When you calibrate, hold your iPhone as you'd normally hold. Don't hold it "perfectly" because that's not how you hold it during normal use. Then, calibrate the finger.
While calibrating, please ensure that you put your fingers in all possible positions including edges & tips of your fingers; all parts of your finger should be scanned. Also ensure that your finger touches the metal ring around the Home button. If you're using a case or screen protector, make sure it doesn't cover the Home button or the surrounding ring. If it does, remove the case or screen protector and try again.
This will help you later when you use your fingerprint to unlock your iPhone 6 or 6 Plus.
In other case, dampness, moisture, sweat, cold – all of this plays a role in preventing the TouchID from working correctly. This happens both ways: if your finger is damp or if the home button has some moisture over it.
Well, if you have set your Touch ID with just one of your fingers, you may face a problem if that particular finger gets damaged and the upper layer of your finger has become rough for some time. Hence, it is always advisable that you set Touch ID with more than one fingers of yours.
Obviously, this is not supposed to be a valid point but seeing that you can use multiple fingers under one fingerprint, I think this should be taken a tad too seriously. Make sure you only calibrate one finger for one fingerprint listing.
Keeping the phone clean goes beyond wiping the home button when you use it. The problem with iPhones is that dust can get under the home button.
Just follow the step-by-step tutorial below to solve "Touch ID is not working" error after iOS 10 update and get your Touch ID working normally:
Step 1: Launch Settings on your iOS 10 running iPhone or iPad, then tap on Touch ID & Passcode and enter your Passcode.
Step 2: Tap on the fingerprint you're having problems with, then tap the "Delete Fingerprint" button.
Step 3: Tap on the "Add a Fingerprint…" button to begin re-scanning the finger you deleted.
Step 4: Place your finger on the Touch ID sensor in various ways – right-side-up, up-side-down, and sideways until the fingerprint icon becomes fully colored.
Step 5: When asked to adjust your grip, scan the edges of that finger until the fingerprint icon becomes fully colored.
Step 6: Tap on the "Continue" button when the process is complete to save your fingerprint.
With any luck, that'll get Touch ID working again and you'll be happily authorizing away! If this issue still cannot be fixed, you'd better get an Tenorshare iCareFone, which can thoroughly help your fix it up.
