1. Fingerprint Sensor Not Touched Firmly

Problem

If the fingerprint sensor fails to recognize your fingerprint, it might be due to inadequate pressure. This could also be due to improper finger placement on the sensor.

Solution: Firm Placement

Ensure you firmly place your finger on the sensor, covering it entirely. Avoid too much pressure, but make sure the sensor fully contacts your fingerprint.

2. Device Showing Glitches

Problem

Glitches or software bugs in your Pixel device may cause disruptions. This can include issues with the fingerprint sensor’s functionality. These problems can range from minor issues to severe software glitches.

Solution: Restart Your Pixel Device

One of the easiest and simplest solutions is to restart your Pixel phone. You can do that by pressing the “Power” and the “Volume Up” keys. It will lead to a pop-up power menu where you must choose “Restart” to reboot your device.

3. Outdated Firmware

Problem

An outdated operating system or firmware can lead to compatibility issues. This can lead to malfunctioning features like the Pixel 6A fingerprint sensor not working.

Solution: Check for Updates

The best way to resolve this issue is to update your Pixel device. Having an outdated version of Android OS can lead to an accumulation of bugs and glitches. Moreover, it can seriously affect the Oppo A2 device’s performance, causing many issues. Here is how to check and update your Pixel phone:

Instructions. On your Pixel device, access the “Settings” app. Within Settings, scroll down to tap the “System” option. On the following screen, hit the “System update” option to check if any latest update is available. Here, if you see any updates, download and install them promptly. Before initiating the update, ensure your device is connected to a stable Wi-Fi network with sufficient battery charge.

4. Dirty Phone or Sensor

Problem

Accumulated dirt, dust, or residue on the phone or fingerprint sensor can cause obstruction. This can lead to the failure to properly recognize your fingerprint.

Solution

1. Cleaning the Phone

Employ a gentle, dry microfiber cloth for wiping down the complete surface of your Pixel device. Take particular care to thoroughly clean the region surrounding the fingerprint sensor. Refrain from utilizing rough substances or strong chemicals as they could potentially cause harm to the Oppo A2 device.

2. Fingerprint Sensor Cleaning

Gently wipe the fingerprint sensor area using a clean, dry cloth to ensure thorough cleaning. For better results, consider using a dampened cotton swab with water or isopropyl alcohol. Before using it again, ensure the sensor is entirely dry.

3. Compressed Air or Soft Brush

Use compressed air or a soft brush if there’s visible debris or particles around the sensor. Be cautious not to apply excessive pressure that might damage the sensor.

5. Screen Protector: Dirty or Damaged

Problem

A smudged or impaired screen protector might disrupt the working of the fingerprint sensor. This can potentially cause it to fail to recognize your fingerprint.

Solution

1. Clean the Screen Protector

Start by effectively cleaning the screen protector on your Pixel device. For a thorough cleaning, consider utilizing a screen cleaning solution. Ensure that the screen protector is free from any dirt or debris.

Problem

2. Avoid Oily or Greasy Substances

Refrain from touching oily or greasy surfaces before using the fingerprint sensor. These substances can transfer onto your fingers, affecting sensor accuracy. If your fingers are dirty or damp, pause to clean them using a dry, clean cloth.

7. Covering Screen if Fingerprint on Screen

Problem

Fingerprint marks or smudges on the screen might disrupt sensor functionality. This leads to inaccurate recognition when you try to unlock your device.

Solution: Adjust the Setting To Consistently Display the Sensor
