Linux on Phones Gets Smoother: postmarketOS v25.06 Launches with systemd
postmarketOS, the Alpine Linux-based mobile OS project, has released v25.06, marking a significant milestone in its evolution. This version introduces systemd support, major mobile interface upgrades, and expanded hardware compatibility, all while staying true to its roots of offering a secure, customizable Linux experience on mobile and embedded devices.
Key Technical Advancements
systemd Comes to postmarketOS
For the first time, postmarketOS supports systemd as an alternative to OpenRC. While OpenRC remains fully supported, systemd provides greater compatibility with mainstream Linux applications and simplifies development workflows.
Note: Switching to systemd requires a fresh installation using the --systemd flag in pmbootstrap.
Based on Alpine Linux 3.22
Staying in sync with its upstream base, postmarketOS now aligns with Alpine Linux 3.22, gaining improved security, performance, and software availability out of the box.
Redesigned Installer for Desktops and Tablets
The new os-installer offers a graphical, user-friendly interface tailored for encrypted installations on laptops, tablets, and convertibles via bootable USB media.
Mobile Interface Upgrades
Each of the major mobile UIs has received updates to enhance usability, visual polish, and hardware support.
GNOME 48 (Mobile)
Improved multitouch input
Triple buffering for smoother rendering
Cleaner font rendering and UI adjustments
KDE Plasma Mobile 6.3.5
Refined quick settings
Better task switching animations
Improved volume and power menus
Phosh 0.47.0
Customizable lock screen wallpapers
Enhanced haptic feedback settings
Default keyboard is now Stevia
Sxmo 1.17.1
Continues to use OpenRC by default
systemd users can experiment via manual setup
A Community-Created Wallpaper
The v25.06 release features a new default wallpaper called “Evergreen”, chosen via a community poll on Mastodon. The geometric design reflects the modern aesthetic of the project while maintaining its vibrant identity.
Optimized Apps for Mobile Use
postmarketOS continues to improve desktop-class apps for mobile screens:
mobile-config-firefox now allows per-site user agent overrides (great for sites like YouTube)
mobile-config-thunderbird brings email to mobile in a more touch-friendly way
Device Support and Kernel Improvements
OnePlus 6 / 6T: Initial camera support introduced
MSM89x7 series (e.g., Redmi 3S/4, Moto E5 Plus): Now supports camera, audio, charging, suspend, and flashlight
Ongoing enhancements across other community-supported and testing devices
Known Issues to Note
Some users may encounter the following:
Sensor proxy regressions
Wi-Fi instability on certain Qualcomm chips
Microphone or display issues on specific devices
Surface RT docking adapters not functioning
Fixes are documented or actively being worked on by the community.
Upgrade Instructions
Existing OpenRC users can upgrade as usual with pmbootstrap, without needing reinstallation.
Those wishing to adopt systemd must reinstall with the correct flags (--systemd) during installation.
What’s Next for postmarketOS?
The project is undergoing a community-led renaming — voting will follow soon.
Expect presence at upcoming FOSS events: FOSSY, FrOSCon, KDE Akademy, and Linux Day Palermo.
A new blog post will arrive in July 2025, keeping the community updated with progress.
Final Thoughts
postmarketOS v25.06 is not just another release — it's a statement. With systemd support, smoother UIs, and a growing base of supported devices, it’s closer than ever to becoming a mainstream alternative for privacy-conscious mobile users.
Whether you’re breathing new life into old hardware or experimenting with Linux on your phone, this release provides a stable, modern, and community-driven platform to do it all.
