However, quite recently a lot of reports have been coming in of the fingerprint sensors on Galaxy devices not working properly. The sensors don’t register the user’s finger and the phone is not unlocked. This problem has been seen to recur for every Galaxy device every once in a while.
What Prevents the Fingerprint Scanners from Working Properly?
After receiving numerous reports from frustrated users we decided to investigate the issue and formed a list of solutions after implementing which the problem went away for most of the users. Also, we identified the reasons due to which the problem is triggered and listed them below. Now that you have a basic understanding of the nature of the problem we will move on towards the solutions. Make sure to implement these solutions in the specific order in which they are provided to avoid any conflicts.
Solution 1: Checking Biometric Hardware
In order to figure out whether the issue lies within the hardware or the software, we will be conducting a test on the sensor. For that:
Solution 2: Checking for Updates
There were many instances where the Android software provided by the Samsung wasn’t properly configured and it malfunctioned due to which the fingerprint sensor was not working. Therefore, in this step, we will check to see if any update is available to fix the software problem. For that:
Solution 3: Disabling Fingerprint Gestures
Sometimes, the fingerprint gestures feature can interfere with the fingerprint scanning feature and prevent it from working properly. Therefore, in this step, we will be disabling the Fingerprint Gestures Feature. For that:
Solution 4: Adding New Fingerprints
It is possible that the database where the fingerprints are stored has been corrupted due to which the feature is not working properly. Therefore, in this step, we will be re-establishing that database and deleting the old data. For that:
Solution 5: Wiping Cache Partition
In some cases, the cache stored on the device can become corrupted and start interfering with important system functions. Therefore, in this step, we will be wiping the cache partition. For that:
