Samsung's brightly-colored Good Lock user interface made its debut on the Galaxy S7 last month, and the manufacturer is now making the UI available on last year's flagships as well. The Good Lock app is now available for download on the Galaxy S7, Galaxy S7 edge, Galaxy S6, Galaxy S6 edge, Galaxy S6 edge+, Galaxy S6 Active and Galaxy Note 5.
Users in United States, the United Kingdom, Canada, Australia, Singapore and Korea can head to Galaxy Apps to download the alternate UI. Good Lock makes sweeping changes to TouchWiz's traditional lock screen and notification shade, introducing bright colors and animated scrolling lists.
Samsung has mentioned that it will roll out bi-weekly updates to the UI, adding new features as requested by users. Should you not be satisfied with what's on offer with Good Lock, you can uninstall the app to switch back to the stock TouchWiz interface.
