ZTE Blade V70 Vita: Fix Fingerprint Sensor Not Working (Step-by-Step Guide)

Troubleshooting Fingerprint Sensor Issues

• 💡 If your ZTE Blade V70 Vita's fingerprint scanner is not recognizing your fingertip, you'll need to set up a new fingerprint.
• 🎯 Begin by navigating to Settings → Security & Privacy → Device Unlock, then select Face & Fingerprints and enter your password.

Preparing for New Fingerprint Enrollment

• 🧼 Before deleting old data, remove the smartphone case for better access and results.
• 🧽 Carefully wipe the fingerprint scanner surface with a microfiber cloth or a clean cotton t-shirt to ensure it's clean and smooth.

Re-enrolling Your Fingerprint

• 🗑️ Tap 'Edit fingerprints', select the old fingerprint, tap 'Delete', and confirm.
• 👆 Tap 'Add fingerprint', then 'Start enrollment', and place your fingertip on the scanner.
• ✍️ Initially, press the scanner with the middle part of your fingertip, then gradually add the edges of your finger by pressing down.
• ✅ Tap 'OK' to confirm the new fingerprint enrollment.

System Checks and Restart

• ⚙️ Before testing, go to System → System Update to check for any available software updates.
• 🔄 If an update is available, download and install it, then restart the phone to apply all changes.
• 🚀 If no update is available, proceed to restart the phone by pressing the power button and volume up keys simultaneously, then select 'Restart'.

Testing the Fingerprint Sensor

• 🔒 After the phone restarts, unlock it with your regular password first.
• 👍 Then, try using the fingerprint sensor with your enrolled fingertip. Test it a couple of times to ensure it works properly.
