Samsung Good Lock is arguably the most underrated tool for Samsung users. This free app gives you access to dozens of customization modules that fundamentally transform the One UI experience. Here's the complete 2026 guide with all new modules.
🔧 What Is Good Lock?
Good Lock is an official Samsung app (available through Samsung Galaxy Store) that acts as a gateway to a collection of modules. Each module modifies a specific aspect of One UI — from the lock screen and notifications to camera settings and multitasking. Think of it as the “hidden Settings” Samsung doesn't put in the main menu.
The app is completely free, doesn't require root access, and works on all Samsung Galaxy devices running One UI 6 or newer. With One UI 8 (2026), Samsung added 4 new modules and upgraded several existing ones.
