Sorry I might be disturbing a bit.
Well, Im trying to understand better a crusade. Against samsung and sony bad software support, but not only.
I have lot of smartphone models. Almost all of them are 2011-2022. Working with LTE. But not Volte. In my opinion, this is inacceptable from the industry.
So after leaving huawei P8 lite 2015 (LOS14), now Im using xperia h8216, with latest lineage 20.
Unfortunately, Volte and wowifi doesnt works : ISP says all information has been transmitted to manufacturers. Some of them (sams/sony) doesnt want to update them (moar sells!) or just find old phone too old. Well, 4G/LTE 2015 devices were costing a lot, and never saw volte.
I saw Jolla and sailfishos a long ago.
Before that, I tried postmarketos. On a samsung A3, system works a bit well, some bugs, LTE works after an hour of trying to hang the network. But it worked, except… volte.
then, I saw those threads :
I understood that OSS communities, including your, were working a lot to get volte well. Free Mobile french ISP did it with maybe 2/3 years of late. With this, two big manufacturers denied to update their software with the volte configuration. But having a glance of the whole schema :
*could sailfish configuration be exported to android or lineage phones?
*I also have a long list of serveral smartphones running android (or something else) ; maybe they could run sailfishos, to get a better software than old android?
you might be surprised by the “old” criteria of some models, but their all well 4G compatible. Maybe sailfish could save them, for a backup daily use? With a §, are the models I hope they could be compatible…
