One of the biggest benefits of the front-mounted Ultrasonic Fingerprint Sensor on the Galaxy S10 and S10 + is that you no longer need to physically pick up your device and reach backwards to unlock it. Instead, just place your finger on the screen to facilitate access and increase comfort – at least on paper.
Unfortunately, the in-display sensor still has some wrinkles that need to be ironed out, and is not as reliable as we would like it to be as a result. With a recent update, the reliability problem has been mitigated for many. However, if you are one of the unfortunate people who still have the problem, there is an alternative to the sensor that you can now enable to unlock your S1
The Galaxy S10 Face Unlock feature provides a happy medium between security and instant access. If you set a specific setting, unlocking your phone will be even faster. Granted, it's not as safe as using a fingerprint sensor because, theoretically, someone could unlock a photo from your device, but this scenario is highly unlikely in most situations.
Settings> Biometrics and Security> Face Detection> Face Unlock
Follow the menu above to find this setting. Once you're on the Face Unlock page, you'll disable the Disable Lockout option so you do not have to swipe up after detecting your face. If you want to speed up the security feature even further, you can also enable "Faster detection" to speed up the unlock process.
Remember that these functions are not without risks. Disabling the "Keep on lock screen" option increases the risk of unwanted access by bypassing the extra level of security that needs to be flipped up. Enabling "Faster Detect" also compromises safety, as facial recognition is less thorough in facial recognition to speed up unlocking. But for most people in most real-life situations, Samsung's Face Unlock is more than enough security.
