Weekly GNU-like Mobile Linux Update (12/2026): Immutable Ambitions

This past week: postmarketOS introduces Duranium immutable variant, PureOS Crimson beta and Sailfish OS 5.0.0.77 early access released, a Ubuntu Touch Q&A, Amazfish 2.9.0 and more! Enjoy!

LINux on MOBile

In preparation for daily driving #MobileLinux I've been thinking a lot about what must be done for reliable and power-efficient push notifications.

Spoiler alert: while UnifiedPush may be a relevant service for some apps, it's not where platform dev focus should be. We want a future full of p2p apps that reject permanently-addressable "servers" entirely, after all! And centralization is not where the bulk of the power-saving magic is anyway. The "magic" is in the fact that the SoC can be in deep sleep and the modem will still wake it up with an interrupt when data arrives on an open connection. It should be fine to have apps' own service processes listen for notifications!

My rough sketch of a to-do list would be:

  • making sure wakeups don't turn the display on xD
  • research into what's needed to set up filtering on the modem for which sockets can wake the SoC up (but initially, fine to just rely on "nothing else has open sockets anyway, only the background services waiting for pushes" maybe?)
  • easy API for establishing the push connection specifically over mobile data if available (since only modem supports wakeup well rn)
  • support for robust background services: unlike what the Background portal offers now, let #Flatpak apps install systemd-user services, which would have metadata connecting them to the .desktop entry, making them introspectable and accountable via settings GUIs (not via control center popups! they shouldn't show up as "annoying left-over in-process thing possibly eating battery"! they're a different thing, expected to run permanently!)
  • actually getting apps to separate push notification listeners into background services

Streaming music over mobile data and playing it on the stereo speakers \o/ Mic also works now… well the top mic at least xD

#postmarketos is getting more and more stable. Its my 5th week since I've flushed OS.

@TobiasFrey @heiseonline #linuxmobile macht große fortschritte. ich schreibe dies auf einem #mobian #phosh. schau auch nach #postmarketos

apparently there are 2 free wireless carriers in the US

- TextNow
- Helium Mobile

textnow operates on ads and helium mobile relies on u sharing ur location 24/7 (tho im sure textnow also does this. its known that mobile carriers do this to some degree. but precise location tracking is crazy)

edit: helium no longer requires location tracking https://nitter.net/helium_mobile/status/1973500013180297611

i wonder if #PostmarketOS devices can somehow use this to their advantage for testing purposes

It seems that the only device that has support for camera on postmarketOS is the Purism Librem 5.
Am I missing any other?
