We will meet the Galaxy Note 4 next week, where it should feature the same Synaptics Natural ID fingerprint technology that is found in Samsung's flagship smartphone, the Galaxy S5. Not only that, but the Galaxy Note 4 should feature added functionality compared to the sensor featured in the S5.
SamMobile is reporting that the Galaxy Note 4 should feature two notable changes in its fingerprint sensor, with the first being the ability to control which application opens when you swipe your finger. This allows users to program a specific application to open up when they swipe their thumb, with the app opening up and displaying in front of you instantly - instead of your finger unlocking the phone, and then having to navigate to the app you were going to use anyway.
The second feature is that you will be able to save passwords and log into websites, with the new Web sign-in feature allowing you to visit sites like Amazon, Gmail and many others where your username and password have been remembered. Instead of typing in your password, you'll be able to swipe your finger on the sensor, where the browser will then enter in your credentials for you. These new features will be added to the what the Galaxy S5 is already capable of.
