Fingerprint scanner does not work

Modern technologies with the use of advanced developments greatly facilitate our lives. They are applied in all spheres of human activity and seek to improve performance. Manufacturers of telephones and computer equipment also use the experience of high technology in their devices. Not so long ago, a touch screen was used in phones instead of a button layout.

In addition, manufacturers have placed in the body of smartphones special sensors that recognize a fingerprint and identify it to the user. This development is used to unlock the screen, registration, quick launch applications and even when paying for services. Despite the high-quality assembly sometimes failures in the scanner prints. In this case, you have to return to the usual introduction of passwords. Sometimes the phone may not respond at all. How much does a fingerprint stop working?

Before you start solving the problem yourself and repair, it is necessary to accurately determine the source of the fault and assess the condition of the equipment. The most common causes are the following system malfunctions:

• Mechanical damage and breakage of the touch panel. Large cracks and strong defects can distort recognition of biometric data.
• Software crash, which resulted in a reset.
• Poor quality of the phone and its work is possible with the purchase of a fake version of the equipment.
• Infecting a phone with a virus program and damaging the operating system.
• Contamination of the scanner sensor with large particles of dust, dirt and foreign objects.
• Water or other liquids on the fingerprint recognition sensor.
• Change of print on print for any reason (damage, operation, severe burn ...).

This is a list of the most common causes faced by users. As can be seen from the options for the reasons, mechanical failures and system failures in the phone are highlighted.

IMPORTANT: You can try to correct external defects yourself, and it is better to entrust the solution of issues with system failures to professionals.

If you manage to find the source of the problem, you can proceed to repair or configure the relevant system parameters. In the case when the problem could not be identified, try the following steps before contacting specialists.

1. In the absence of visible defects, clean the phone from dirt.
2. Then treat the sensor button with a cotton swab dipped in alcohol solution.
3. Wipe the device with a dry cloth, then try to activate it.
4. Try updating the software version or vice versa returning the previous parameters.
5. If there is no interaction with the system or if the pattern on the fingers is changed, you can return to the factory settings, and you can also use your finger in the settings to activate it.

IMPORTANT: To provide free diagnostics and repair of equipment, you must use the warranty.

To keep it true, do not make independent interventions. Just take the product to the store where the purchase was made, or to another service center.
