@goldkiddo dunno if opensource community version, but indeed with Jollaphone you need account to get updates 🙁

And, yes, for me Jolla Phone is only step while waiting really working Linux phone. I've been tested PinePhone which worked somehow, but was slow and all ways poor quality hardware. I have also PinePhone Pro, but it's expensive joke. There's no phone where PostmarketOS runs so good it can be use daily and mainly (only phone). Bank apps are mandatory, so also somehow working camera and bluetooth. Other Applicationa I've been tested I can replase easily with Linux natives. I've been thinkind many times, apps are great. Both Phosh and Plasma Mobile (my favor!) are great. But... No working hardware 🙁

To that question, idk. Postmarketos is more standard, using the mainline kernel (and having the downside of porting the android kernels, like my smartphone, a Redmi Note 9s, having 4g bugged because of the kernel), having normal applications installed with apk, using the same tools as desktops, but UT uses a hybrid approach, it uses the hybris and halium, that is a compatibility layer on top of the android kernel, but it's heavily built towards snaps, immutable images, that kind of stuff, waydroid didn't work, it seems bugged on my phone as well. Droidian is more standard debian, but with hybris, but I updated the system and it didn't boot, so I couldn't test it, but on my opinion, phosh on droidian > lomiri.

The gold standard to me would be postmarketos with hybris or droidian working well, but only time will tell. I think it's best to shop around.

Too many trees, not enough forest. Edit: Yes, that is exactly what I was asking for, but I guess I should have asked for a place that might just regularly review and summarize and compare OSs so I could research which one I might want to install.

But I do have a Moto G-Power from the generation that was good. I wonder if it would be worth it to update the battery and use that.
