Touch ID is a way you send a command to your iOS device to perform some actions. And when this Touch ID is not working on iPhone 8, 8 Plus, 7, 7 Plus, 6s, 6s Plus and iPad in iOS 11 or iOS 10, iOS users are disappointed. An iOS user normally uses Touch ID to unlock the device, log into apps, use Apple Pay, and buy things from iTunes and App Store.
As long as your Touch ID is working smoothly, you are on cloud nine, but when the Touch ID doesn’t respond your commands, you wish you had not purchased an iPhone or iPad.
So when you can’t access anything with Touch ID on your iPhone or iPad, you should perform some solutions listed here. But before that, you need to do some homework or primary things on your iPhone or iPad.
What to Do When Touch ID Doesn’t Respond on iOS Device.
There can be multiple reasons for Touch ID stopped working after iOS updating or resetting on your iPhone or iPad.
You should be careful about:
Successful Calibration of Fingerprint
Normally, users fail to calibrate fingerprint to use Touch ID feature on their iPhones or iPads. While calibrating your fingerprint, you need to change the positions of your thumb or finger you want to calibrate. Put your fingers/thumb in all different positions; also ensure that your finger or thumb touches the metal ring of the scanner. In practice, you are not going to put your finger in a perfect position; you may place it randomly. This means, you should place your finger in all possible positions during the process of calibration.
Use dry finger on dry Home button
If your finger is damp, you need to make it dry as bone and then place it on Home button. Secondly, Home button should also be neat and clean. Even a little moisture on Home button would stop you from accessing your iPhone via Touch ID.
Is your finger damaged?
Apart from soft technology, if you have laid your hands on something hard and menial task, you may hurt your fingers. And in case, you have damaged a finger with which you unlock your iPhone or iPad, the Home button may not identify your fingerprint. A piece of advice: you should register more than one finger for Touch ID.
Keep your iPhone/iPad Neat & Clean
When dust enters the Home button, it reacts weirdly. Simply keep your iPhone clean with essential accessories like iPhone cases, screen protectors etc. Moreover, if you regularly go outdoors for biking, jogging and other adventurous activities, it is recommended that you use accessories like iPhone armbands and waterproof cases for iPhone.
Last but not the least, you must set one finger for one fingerprint as Touch ID. As far as possible, do not use multiple fingers for one fingerprint.
