It can be frustrating when the fingerprint sensor on your Motorola phone doesn’t work as expected because it is a convenient and secure way to unlock your device.
Quick information about the Motorola fingerprint sensor
The Motorola fingerprint sensor is designed to be compatible with most screen protectors. However, some thicker or lower-quality screen protectors may interfere with the sensor’s ability to read fingerprints.
If you’re having trouble using the fingerprint sensor after installing a new screen protector, try removing the screen protector and see if that solves the problem.
Motorola fingerprint sensors are not compatible with wet hands or fingers. If your hands are wet, dry them before using the fingerprint sensor.
Motorola fingerprint sensors are not compatible with gloves. If you need to use your phone while wearing gloves, you can use a PIN or pattern unlock method.
Troubleshooting tips for specific Motorola fingerprint sensor issues:
If your fingerprint sensor doesn’t respond, try cleaning it with a soft, lint-free cloth.
If the fingerprint sensor responds slowly or fingerprint recognition frequently fails, try adding your fingerprint again.
If your fingerprint sensor randomly unlocks your phone, try turning off the “Unlock with wet fingers” option in the Settings menu.
There are many reasons why your Motorola fingerprint sensor may not be working. Here are more detailed troubleshooting tips for the Motorola fingerprint sensor not working.
1. Clean the fingerprint sensor
The fingerprint sensor is a sensitive component that relies on accurately reading fingerprint ridges. Over time, dust, dirt, oil, and even small particles can build up on the sensor, hindering its ability to capture your fingerprint properly. It is important to clean the sensor regularly to ensure optimal performance.
Here’s how to effectively clean your Motorola fingerprint sensor:
- Gather a soft, lint-free cloth, preferably a microfiber cloth, and isopropyl alcohol.
- Lightly dampen the cloth with isopropyl alcohol, avoiding excessive moisture.
- Gently wipe the entire surface of the fingerprint sensor in a circular motion.
- Do not apply excessive pressure, as this may damage the sensor.
- Let the sensor dry completely before using it again.
2. Make sure your fingers are dry and clean
Moisture, oil, and foreign substances on your fingers can greatly affect the fingerprint sensor’s ability to read your fingerprint accurately. To ensure proper registration, please follow these guidelines:
- Wash your hands thoroughly with soap and water and remove any traces of dirt, oil, or lotion.
- Dry your hands thoroughly with a clean towel before using the fingerprint sensor.
- Avoid applying lotions or moisturizers to your hands, as they may leave residue that can interfere with sensor performance.
3. Place your finger on the sensor and apply the appropriate pressure
Fingerprint sensors are designed to register fingerprints when a certain amount of pressure is applied. Applying too little or too much pressure can reduce the sensor’s ability to capture your fingerprint accurately.
Here’s how to apply appropriate pressure when using the fingerprint sensor:
Place your finger straight on the sensor and ensure all edges of your fingerprint are within the boundaries of the sensor. Apply firm, even pressure to the sensor when placing your finger on it.
Don’t press too lightly. The sensor may not be providing enough pressure to read your fingerprint. Conversely, do not press too hard, as this may damage the sensor.
4. Cover the entire sensor with your finger
The fingerprint sensor must capture your fingerprint to match your registered fingerprint accurately. If only part of the sensor is covered, your fingerprint may not be read accurately.
To obscure your entire fingerprint:
Place your finger straight on the sensor and ensure all edges of your fingerprint are within the boundaries of the sensor.
Do not tilt or tilt your finger. This ensures that only a portion of the fingerprint is captured. Do not move your finger while the sensor reads your fingerprint.
5. Check for software updates
Software updates often include bug fixes and performance improvements that can resolve issues related to the fingerprint sensor. Regular software updates ensure your phone runs the latest optimization and security patches.
Here’s how to check for software updates:
- Connect your phone to a Wi-Fi network.
- Go to Settings > System > System Update.
- If an update is available, the system prompts you to download and install the update.
Once the update is complete, restart your phone and check if the fingerprint sensor is working properly.
6. Remove and re-add fingerprints
Occasionally, the fingerprint sensor may malfunction due to problems with registered fingerprints. Removing and re-adding the fingerprint often resolves these issues.
Here’s how to remove and re-add your fingerprint:
- Go to Settings > Security > Fingerprint.
- Select Remove all fingerprints.
- Check fingerprint removal.
- After removing all fingerprints, proceed with the process of adding fingerprints again.
- To register your fingerprint correctly, you must carefully follow the on-screen instructions.
7. Restart your phone
Restarting your phone can often fix temporary glitches and software issues affecting fingerprint sensor functionality. Often, minor problems can be resolved by simply restarting without the need for more complex troubleshooting.
Here’s how to restart your Motorola phone:
- Press and hold the power button until the power menu appears.
- From the Power menu, select Restart.
- Wait until your phone fully restarts.
- After restarting, check if the fingerprint sensor is working properly.
8. Perform factory reset
A factory reset should be considered a last resort, as it will erase all data on your phone. Back up your important files and data before continuing.
Here’s how to factory reset your Motorola phone:
- Go to Settings > System > Reset option.
- Select Erase all data (factory reset).
- Follow the on-screen instructions to complete the factory reset process.
- First factory reset
