Samsung Galaxy smartphones offer robust security features, with fingerprint scanning being a primary method for unlocking devices quickly and securely. Beyond just accessing your home screen, however, lies a convenient capability many users overlook: using your fingerprint recognition process to launch specific applications almost instantly. This functionality streamlines access to your most frequently used apps, saving you the time and effort of navigating through your home screen or app drawer after unlocking. Setting this up leverages the customization options available within Samsung's One UI, specifically focusing on the lock screen environment. While you don't assign an app to a unique fingerprint *itself*, you can configure shortcuts that appear on the lock screen immediately upon successful fingerprint recognition, allowing for a seamless transition from unlocking to launching an app. The process begins, naturally, with ensuring your fingerprints are registered accurately on the device. If you haven't already, navigate to Settings, then Security and privacy (or Biometrics and security on older One UI versions), select Biometrics, and then Fingerprints. Follow the on-screen prompts to add one or more fingerprints. Once your fingerprints are registered, the next step involves customizing the lock screen shortcuts. Access your phone's Settings menu again, and this time select 'Lock screen'. Within the Lock screen settings, look for an option labeled 'Shortcuts'. Tapping this will typically show options for the left and right shortcuts displayed at the bottom corners of your lock screen. You can assign various functions or apps to these positions. To achieve the goal of quick app access via fingerprint unlock, simply tap on either the Left shortcut or Right shortcut option and select 'App' from the list of actions or choose a specific application directly from your installed apps list. For instance, you could set your messaging app to the left shortcut and your camera to the right. Now, when you place your registered finger on the sensor, the phone unlocks, and these two app icons appear immediately in the corners. A quick tap on the desired icon launches the application without needing to swipe or navigate further. This method effectively links the fingerprint unlock action to immediate app accessibility, making it feel like the fingerprint itself is opening the app. It transforms the unlock process into a gateway for your essential applications. This feature enhances efficiency, particularly for apps you need to access frequently and quickly throughout the day, such as communication tools, payment apps, or productivity software. While typically limited to two customizable shortcuts directly on the lock screen, this is often sufficient for most users' primary needs. Exploring Samsung's Good Lock application suite, available from the Galaxy Store, can sometimes offer even deeper customization for lock screen actions and routines, potentially providing alternative ways to trigger apps based on unlock methods, though the standard shortcut feature provides a straightforward and effective solution integrated directly into the core system settings. Leveraging these built-in capabilities allows for a more personalized and efficient smartphone experience.
