I am writing to bring to your attention an issue I am facing with my iPhone 5 SE. I am encountering an error related to the Touch ID setup. When trying to complete the setup, I receive the message "Unable to complete Touch ID setup."

Make sure you have the latest version of iOS or iPadOS. Make sure your fingers and the Touch ID sensor are clean and dry. * For the Touch ID sensor, use a clean, lint-free cloth to wipe off any dirt or debris. Your finger should cover the Touch ID sensor completely, touching the surrounding metal ring.

If Touch ID isn't working on your iPhone or iPad - Apple Support

If you're encountering the message "Unable to complete Touch ID setup" while setting up your iPhone SE 1st Gen, there could be a few reasons for this issue. Here are some steps you can take to troubleshoot and potentially resolve the problem:

1. Sometimes, the issue might be due to dirt, oil, or debris on the Home button or your finger. Make sure both are clean and dry before attempting the setup again.
2. Sometimes, resetting the Touch ID settings can help. Go to Settings > Touch ID & Passcode and enter your passcode. Then, turn off all the options under "Use Touch ID For" (or "Use Face ID For" on later models). After that, restart your iPhone and go back to the same settings to enable the options again.
3. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
   1. Restart the device. That's it.
   2. Still not solved --> Force restart iPhone - Apple Support
4. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
   1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
5. If none of the above steps work, you might need to restore your iPhone using iTunes (on a computer) or Finder (on macOS Catalina and later). This will erase all your data, so make sure you have a recent backup. Connect your iPhone to your computer, open iTunes or Finder, and follow the instructions to restore your device.
6. Make sure you have the latest updates installed.
   1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
   2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.
