Samsung Good Lock software suite

Samsung Good Lock is an advanced system personalization suite designed specifically for Samsung Galaxy devices. Originally launched in 2016 for the Galaxy S7 series, it has evolved from a simple lock screen utility into a powerful ecosystem of modular apps that allow users to deeply customize the One UI user interface. The software is developed internally by Samsung's software engineers in South Korea and is typically distributed through the Galaxy Store,

The brand is a core part of the Samsung ecosystem, reflecting the company's commitment to user-centric software design. While the hardware it runs on is manufactured globally (including Vietnam, India, and Brazil), the software and intellectual property behind Good Lock are rooted in Samsung's South Korean headquarters. Ownership remains entirely under Samsung Electronics, ensuring a seamless integration with Android-based One UI layers on mobile and foldable devices.
