Haven't heard of Samsung's Flow app? Well, the app's just been updated and will let you unlock your Windows 10 PC with your phone.
The Flow's original purpose was to connect your phone to your PC, allowing for file transfers. Now Flow lets you use your fingerprint reader to unlock your Windows 10 PC. Pretty handy, and gives your phone more utility.
Besides file transfers and PC unlocking, the app also lets you enable your mobile hotspot to be used with your PC - easier, quicker way rather than the manual selection from the PC itself.
The app is supported on Samsung's TabPro S as well as the following Galaxy smartphones: Galaxy S7, S7 Edge, S6, S6 Edge, S6 Edge Plus, and the Galaxy Note5.
