If you tried setting up Touch ID on your iPhone, but it does not let you complete the setup don’t worry!
The following part lists the causes of Touch ID not working after replacing the screen and the solutions to the issue.
What Causes Touch ID Not Working After Screen Replacement
For Touch ID to work, you need to make sure of certain things. If one thing is off, you will be facing problems.
Here are the most common reasons why your Touch ID is not working after you replaced the screen.
Dirty Finger and Fingerprint Reader
After replacing the screen, make sure your hands are clean. Sometimes, even a tiny bit of sweat or dirt can make it hard for your device to read your fingerprint.
Incorrect Placing of your Finger
If you scan your fingers improperly, the Touch ID of your iPhone will also fail to recognize print.
There might be a bug or other problem with Apple’s Touch ID that can be solved with an update.
Malfunctioning Touch ID Sensor
If the Touch ID sensor stops working after screen replacement, it may be due to the incompatible third-party accessories used to replace the components or a broken Home Button Flex Cable.
Error in the iOS System
iOS system errors can also cause your Touch ID to malfunction after screen replacement, but you can quickly solve this with a hard reset.
If you recently serviced your device, check for damages. A damaged flex cable or connector may cause the Apple Touch ID not working after screen replacement.

Solution #3: Make Sure the Fingerprint Reader is Clean
