How to Fix ‘Fingerprint Scanner Not Working’ issue on Android Devices: Touchscreen fingerprint sensors are available in a wide variety of designs and sizes. It is generally agreed that the most accurate fingerprint sensors are those that are physically present on the device. These sensors can be placed in the back, front, or even side of the device. In addition, there are fingerprint sensors that are positioned underneath the display, and these sensors are also available in two different flavours.
Although it is capable of producing a two-dimensional image of the fingertips, the optical type is not completely reliable. A three-dimensional map of your fingertip is generated using ultrasonic fingerprint sensors. With that being said, there are a few external elements that have the potential to influence the accuracy of fingerprint identification on mobile devices.
There are a few things that you need to bear in mind before we move on to discussing some of the options that can help you with your fingerprint problems. First, the use of a screen protector tends to decrease the accuracy of fingerprint recognition for sensors that are embedded into the display. Be prepared for a decrease in performance if the screen protector is thick and necessitates the use of UV adhesive during the application process. Here are the ways how to Fix ‘Fingerprint Scanner Not Working’ issue on Android Devices.
