Touch ID Not Working on iPhone 8 or iPhone 8 Plus

Touch ID Not Working on iPhone 8 or iPhone 8 Plus: Solutions

Cover Entire Touch ID Area

Many users have apprehensions that ‘Touch ID won’t let me add fingerprint’. This is not the case; if you gently move your finger on the Touch ID area and cover the entire surface, you won’t face any problem during fingerprint registration. At the same time, you need to check that your finger is scanned through edges in the second round.

Keep your fingers clean

When your iPhone 8 fingerprint failed, you should not blame the device only. Check your fingers before you add a fingerprint on your iPhone 8; your fingers should be clean and dry. Any moisture or oil residue can spoil the Touch ID area, and this can cause trouble in future. If needed, clean the Home button as well.

Screen protector or case should not interrupt Touch ID button

During the installation of screen protector, you may have overlaid the Touch ID button; this obviously can hamper Touch ID authentication. Run a check if the screen guard is applied properly on the iPhone’s touch screen.

Points to Ponder

  • A step-by-step troubleshooting guide may not work every time, and therefore, the issue pops up again and again. In this situation, you can delete the fingerprint and re-add your fingerprint.
  • While scanning the finger on Touch ID button, see to it that your finger is touching the capacitive metal ring and the home button. Do not lift your finger immediately.
  • Make sure you are not moving or shaking your finger too much during scanning.
