The fingerprint sensor on my Samsung Galaxy A30 suddenly stopped working, I tried restarting my set, deleting all the fingerprints and add them again, but none cleared the issue. Adding the fingerprints makes no issue but when "Check added fingerprints" the result was "No match.".
My fingerprint sensor was working properly and suddenly it is not recognizing. My phone didn't fell or anything I don't know why they are not working all of a sudden.
Hi, your device not recognizing your finger print can be due to a number of things. Can be an hardware issue such as a scratch sensor or Software Issue as It is possible that the Android software installed on your device has not been properly configured to use the Fingerprint scanning feature which is preventing the feature from working properly or even by because of a corrupted data or cache. <edit>
