Your phone's fingerprint sensor provides a convenient and secure way to unlock your phone, and keeps your personal information safe with no codes to remember. If you're having issues with your fingerprint scanner there are a number of solutions you can try.
Before you try out the below recommendations as to your solution, be sure to check if your device's software are updated with the latest version. Please check how to update your mobile device's software in the following order.
Step 1. Go to Settings > Software update.
Step 2. Tap on Download and install.
Step 3. Follow the on-screen instructions.
Remove protective cases.
• If a phone case covers or touches the fingerprint sensor, or prevents your finger from touching it, it can interfere with the sensor's operation.
Samsung recommends using the device with Samsung-approved cover accessories for protection of the product's appearance and user convenience.
Moisturize your hands.
• The sensor may not work if your fingers are too dry or chapped. It may be helpful to moisturize your hands with hand lotion.

• To remove fingerprints or dusts, wipe the window glass smoothly with a clean and soft cloth.
• Fingerprint recognition is blocked when the device is under water.
