iPhone Touch ID replacement check
Every iPhone model from 5s to 8 Plus has a Touch ID sensor, which is unique for each phone. It’s not possible to replace the button without authorized service center’s assistance and expect it to work the same way as before.
iPhone’s original Home button is uniquely paired to the logic board at the factory — and without Apple’s calibration process, even the installation of a genuine fingerprint scanner won’t help.
Unable to activate Touch ID on iPhone after replacement?
The button might be an OEM, but still doesn’t work — once it was replaced, it loses a unique pairing with the current iPhone.
Many repairers, testers, and other techs who deal with pre-owned phones try to check the button manually and spend a lot of time on the procedure.
iPhone Touch ID repair issues
What’s wrong with the test of the Touch ID button? The most common problems are:
- Original Touch ID can be replaced with another one and you won’t spot any visual difference. If you don’t test it, there is a chance that Touch ID won’t work, and the phone will be returned in the end. The company that sold such a device will lose its money and reputation.
- The process of Touch ID authenticity check is time-consuming and involves manual interaction, therefore testers process a limited quantity of phones. Also, manual inspection leads to inaccuracy and productivity loss.
