In order to switch to a #Linux phone running something like @postmarketOS, I'd really only need a few things:
Reasonably good battery life. Probably the biggest one.
Consistently working calls and text messages.
A good working web browser.
Maybe some basic local tools like a calendar, notes, and maps.
I think that's basically it. Everything else I think I could reasonably compromise on. Most things can be done from the web browser. Android app compatibility would be nice, but I personally don't feel the need to run things like my banking app on my Linux phone. Obviously I'd like more, but this is the baseline experience that I'd need.
I know that hardware compatibility and battery life are extremely difficult without manufacturer support, and I figure until we have that, these won't be reasonable requests.
@zak I have similarly basic phone needs. And have been daily driving the linux phone FLX1 from FuriLabs for the last few months. And it basically meets the needs you mention. In the US they only support T-Mobile.
@mpanhans What sort of battery life have you been getting? I'm currently using Google Fi, and I have to wonder if it'd work with a T-Mobile MVNO like that.
@zak The battery life is fantastic. I typically go 2-3 days between charges. @Luigi311 wrote a review with a more formal testing and gave it a 5/5 on battery. https://blog-d.luigi311.com/furilabs-flx1/
@mpanhans @zak thank you for linking this and that you found it useful!. It would be best though to point to https://blog.luigi311.com/furilabs-flx1/ the blog-d is my development site so sometimes its out of date or even down as im playing with new changes.
