Touch ID on iPhone is working poorly: how to set up a fingerprint sensor in iPhone

Touch ID fingerprint sensor on a fairly fresh iPhone does not always work when you touch and you have to constantly refer to the password?

If you encounter a similar problem, then in this material we will tell, how to fix it.

Everybody knows, that after buying a new iPhone, you need to perform the activation procedure and initial setup of the device, which includes the Touch ID fingerprint setup, built into the Home button. Users are asked to add a footprint, with which the iPhone can be unlocked.

From our many years of user experience, customizing the new iPhone, it is safe to say, that adding a fingerprint to the Touch ID during the initial setup of the device is often very fast and not always with an understanding of the process. Most users, while setting up a biometric sensor, hold the iPhone completely differently than during normal use. This is the whole secret.

Besides, after the initial setup of the iPhone, few people return to the Touch ID settings (in iOS settings), to continue the process of improving sensor performance. As a result, users continue to use that single fingerprint, which was recorded in Touch ID when you first set up your iPhone. But in the sensor parameters, you can add as many as 5 prints. so…

  1. Open the Settings application on your iPhone or iPad and go to the Touch ID section and the passcode.
  2. Enter passcode.
  3. Remove all added prints. To do this, select each fingerprint and click Delete fingerprint.
  4. Click Add Fingerprint.
  5. Take an iPhone or iPad this way, as usual you hold the device before unlocking.
  6. Go through the process of adding all five prints this way:
  • add the thumbnail of the right hand twice;
  • twice add a thumbprint of the left thumb;
  • one time add the imprint of the right index finger (if you are right handed) or left hand (if you are left handed).

The meaning of this operation is, to add more fingerprints to the most used unlock option. The scheme proposed by us can be changed if desired. for example, if you always unlock the device with one hand, it will not be superfluous to add on Thumb 3, 4 or even all 5 possible prints.

Try it now. In most cases, this will solve the problem of poor performance Touch ID.

When, if after performing the procedure of adding fingerprints the sensor still reacts poorly, try to reboot the device. If the reboot did not help, then there are two options — either you are an owner of hands with an abnormal fingerprint (we met such users) or the problem is still in the Touch ID sensor.
