Fingerprint scanner does not work

Modern technologies using advanced developments make our lives much easier. They are applied in all areas of human activity and strive to improve performance. Manufacturers of telephones and computer equipment also use high-tech experience in their devices. Recently, phones began to use touch screens instead of push-button layouts.

In addition, manufacturers have placed special sensors in smartphones that recognize a fingerprint and identify the user by it. This development is used to unlock the screen, register, quickly launch applications, and even when paying for services. Despite the high-quality assembly, sometimes the fingerprint scanner malfunctions. In this case, you have to return to the usual password entry. Sometimes the phone may not respond at all. Why did my fingerprint stop working?

Why doesn't the fingerprint scanner work?

Before you begin solving the problem and repairing it yourself, you need to accurately determine the source of the malfunction and assess the condition of the equipment. The most common possible causes are the following system failures:

• Mechanical damage and breakdown of the touch panel. Large cracks and severe defects may interfere with biometric recognition.
• A software failure resulted in the settings being reset.
• Poor quality of the phone and its operation is possible when purchasing a counterfeit version of the equipment.
• The phone is infected with a virus program and the operating system is damaged.
• The scanner sensor is contaminated with large particles of dust, dirt and foreign objects.
• Water or other liquid has come into contact with the fingerprint recognition sensor.
• Changing the pattern on the print for any reason (damage, surgery, severe burn...).

This is a list of the most common reasons faced by users. As you can see from the variants of reasons, mechanical faults and system breakdowns in the phone stand out.

IMPORTANT: You can try to fix external defects yourself, but it is better to entrust the solution to system failures to professionals.
