@djlink Well... There are minimums and there is real endurance. And real endurance depends on many things, including health. New SSD will retain data longer than SSD at end of life, for example. You'll likely get more than year in real use. But yes, it is more complex and no, SSDs are not forever.

@janvlug @khalid @postmarketOS @purism #librem5 is a great development board. It is also great computer. Before thinking you could use it as a phone, ask about battery life.

@allpurposemat @ollieparanoid In my case it was plain to see -- I did top, and gsd-color was just sitting that at 30% (?) of cpu. So I SIGSTOPed it :-). You probably don't have same issue.

@allpurposemat @ollieparanoid It was gsd-color itself... and stopping it did not seem to have ill effects.

@as400 @khalid @postmarketOS Actually... Samsung S4 Mini VE worked/works for me, quite reliably. Downside it earpiece does not work, so you are always on speaker, but I'm pretty sure there's some other phone that works better.

Gnome Software has this "wheel" button on packages... you press it, and it updates the package. That's not what I would have guessed it would do.

What is worse phone (OnePlus 6 with PostmarketOS) no longer sees the wifi. Any ideas besides "wipe and start again"?

This is what my fosdem talk will be about... and also fallback if hdmi from phone fails. My notebook with real slides is too far away due to mistake.

@fossdd @martijnbraam Ah, interesting, thanks for a pointer! I looked at various kaios devices, and they seem to be ~ same weight as the samsung s4 mini... and s4 will be easier to support.

@martijnbraam Thanks. Call audio is important to me. (Samsung S4 mini VE works, but only with loudspeaker... and battery life is ~20 hours. Not great, not terrible.)

gsd-color. Not sure what it is supposed to do, but what it does is turning phone into hand warmer. killall -STOP gsd-color seems to fix it. #postmarketos on Samsung S4 mini VE.

@gravitylord I may have misparsed the article. Anyway, requiring subscription for features user's hardware already has is not ok, either.
