The Samsung Galaxy S25 Ultra, while boasting impressive hardware specifications, has faced criticism regarding its ergonomics and one-handed usability. However, a solution has emerged through Samsung's own Good Lock app, which significantly enhances the user experience of this flagship device.
S25 Ultra Specifications:
- Brighter and sharper display compared to iPhone 16 Pro
- One UI 7 interface
- Android 15 base operating system
- Lighter build than predecessor
- Flatter side design
The Ergonomic Challenge
The Galaxy S25 Ultra's new design with flatter sides, while aesthetically pleasing, has created some usability concerns.

Good Lock: Samsung's Hidden Gem
Samsung's Good Lock application emerges as a powerful customization tool that addresses these ergonomic challenges. The app's One Hand Operation+ module introduces customizable gesture handles on both sides of the screen, allowing users to create up to six different shortcuts through various swipe gestures - straight, diagonal up, and diagonal down.

Users can assign up to 50 different actions to various swipe gestures, effectively transforming the phone's usability. Common customizations include quick panel access, calculator launch, and access to essential tools like Wi-Fi, Bluetooth, and volume controls.
Impact on User Experience
The implementation of Good Lock has significantly improved the S25 Ultra's usability, making it a more viable option for users transitioning from other devices, including iPhone users. The combination of the phone's superior display quality and the enhanced user interface through Good Lock creates a more compelling user experience.
