I don’t have the physical phone yet, but I have been looking forward to having a way to schedule an SMS message to be sent at a certain time. I imagine that this must be possible (using a cron job, if nothing else) on the Librem 5, yet I have no knowledge how I’d do it on my current (Android) phone.
There’s also callen, which is hackersgame’s attempt to fight back against robo-callers, and I’ve been dying to try it out myself.
And these are just two examples off the top of my head… being able to program directly on the device – with no restrictive terms of service, no rooting/jailbreaking process, no extra development fee, etc. – would immediately unlock a world of possibilities.
