Phosh Mobile Phone UI Making Progress On GTK4 Port

Written by Michael Larabel in GNOME on 31 January 2026 at 02:52 PM EST. 12 Comments
Evangelos Ribeiro Tzaras presented today at FOSDEM on the latest work around Phosh, the mobile phone user interface / Wayland shell project for mobile Linux environments. Phosh has been making steady progress and has more features out on the horizon.

Phosh has been advancing a lot in part thanks to NLnet funding for various initiatives such as cell broadcast support. There has also been work on improved power management / energy efficiency, per-country emergency numbers, sandboxed thumbnails, lockscreen wallpapers, auto brightness, and more.

For helping to allow more monetary donations to the project, Phosh mobi e.V. has been established in Germany as a non-profit association for fostering Phosh development.

Some of the future work on Phosh includes completing its GTK4 toolkit port, cut-out support with XDG-cutouts for "notches" type cutouts on some mobile devices, and SIP improvements to GNOME Calls. Again thanks to NLnet funding for backing those initiatives.
