Introduction: Why mobile fingerprint Stop Working suddenly?
Fingerprint Not Working on Android. It is fast, it feels safe and actually it is much easier to unlock your phone. However, when your fingerprint sensor breaks down, or will not identify you, it is irritating. You’re not alone. The problem is faced by a large number of Android users. It may be a software malfunction, a malfunctioning sensor, an expired system update or even a hardware malfunction.
Android phones are highly dependent on fingerprints in order to establish who you are. It can be locked out of your apps, or your phone altogether, when it fails. So, what’s going on? But, more importantly, how are you going to fix it? We are going to consider the reasons behind the issue with fingersprints and provide the measures to be taken to make them work again.
The Android Fingerprint Sensors: How it works.
Prior to taking up trouble-shooting, it is beneficial to have an idea of what you are handling. There are several fingerprint sensors that are used on android phones. Others are capacitive, usually one at the back or side, and newer ones have optical or ultrasonic sensors, which are inbuilt in the display.
These advanced sensors are used in big brands like Samsung, Xiaomi and OnePlus. To put it briefly, the machine scans the individual fingerprint pattern and transforms it into coded digital information.
Nevertheless, when the sensor cannot get a clean reading (because of dirt, sweat, moisture, a low-quality screen protector, or an annoying app), then it will not unlock your phone.
Why Your Fingerprint Not Working .
What’s causing the problem? Oftentimes it is a dirty or smudged sensor. The scan can be interfered with by a drop of oil or dust. Wipe the sensor and check whether the problem has disappeared.
Next: software updates. Weirdly enough, sometimes a significant update of the system can make the fingerprint reader unavailable. When it broke down following an update, then it is probably a software bug.
Another similar cause is physical damage. Have you fallen with a phone or contacted with water? Such damage does not go well with fingerprint sensors. In-screen readers are also very delicate, a crack or a broken screen would make them useless.
Lastly, the registration could have been unfinished initially. In case of the first scan being sloppy or you moved your finger around during configuration, the phone will not easily recognize you in future.
Quick Fix: Clean Fingerprint completely with thinner
The simplest solution is first and most obvious, to clean the sensor. Wipe fingerprint scanner with a soft microfiber cloth. In the case of an in-screen scanner, a phone, make sure that you clean the display where the fingerprint is located.
Avoid harsh chemicals. All that is needed is a small amount of water or an alcohol-based cleaner on a cloth. Wipe your finger with a towel and make sure it is dry.
Detection can be inhibited by moisture in the form of sweat or water. Get towel and ensure that your hands are totally dry before giving it another attempt.

This is a simple procedure that can be used to eliminate simple troubleshooting.

Your finger should also be placed in different angles in the process of registration in order to cover the entire area. Gently press but forcefully as the scanner scans the image.
This will enhance the accuracy of recognition and remove corrupted fingerprint data.
Remove Screen Protector or Thick Case
In case your Android phone has an in-screen fingerprint sensor, then your screen protector is possibly the suspect. There are even thick or low quality protectors that lower the sensitivity of scanning.
Such brands as Samsung also employ ultrasonic sensors, which might not deal with some glass protectors. This can be enhanced by removing or substituting the protector with a compatible protector.
Fingerprint sensors mounted on the sides are also compromised by bulky cases. Ensure that the sensor is not covered by anything.

Long press on power botton Continue to press this power button and choose option of Safe mode.
In case the fingerprint functions in Safe Mode, remove the recently installed apps one at a time until the issue is resolved.

When It’s a Hardware Problem

In case of warranty, it will be necessary to contact the official service center of the brand. As an example, Samsung and Xiaomi customers are expected to visit authorized care services where they can be properly diagnosed. Third-party repairs should not be done when warranty remains open.
