librem5 Interface overview
Playing with the latest snapshot from the Librem5 dev VM.
This video provides an overview of the Librem 5 phone interface, exploring the user experience and design of Purism's Linux-based smartphone. The Librem 5 runs a fully open-source mobile operating system, demonstrating what a privacy-focused, Linux-powered mobile device looks like in practice.
The Phosh Shell
Phosh (Phone Shell) is the default graphical shell for the Librem 5. It's built on top of GNOME technologies and designed specifically for mobile use:
- Touch-optimized UI: Large touch targets and gesture-based navigation
- Adaptive design: Applications can adapt between phone and desktop modes
- GTK-based: Uses standard GTK widgets with libhandy for mobile adaptations
- App drawer: Access to installed applications
- Top panel: System indicators, time, and notifications
- Bottom gestures: Swipe up to access the app drawer or switch apps
- Lock screen: Secure PIN entry with large touch-friendly buttons
- Application testing
- UI/UX experimentation
- Driver and system software development

Development Environment
The Librem 5 dev VM allows developers to test and develop applications before hardware availability. This virtual machine environment mirrors the phone's software stack, enabling:
Comparison with Traditional Mobile OS
Unlike Android's custom Java/Kotlin runtime or iOS's proprietary frameworks, the Librem 5 uses standard Linux desktop technologies adapted for mobile. This means developers familiar with GNOME/GTK development can easily create applications for the phone.
