I'm switching my phone from Android to Linux

That's good news.

But the picture is boring.

Why not switch to GrapheneOS or LineageOS? The former offers more security at the cost of being limited to Pixels and soon-to-be Motorola phones. The latter offers more privacy and greater device support at the cost of not being able to relock the device's bootloader after installing.

Both of these are still reliant on Android and thus Google. Switching to Linux eliminates this concern altogether.

I thought Jolla / Sailfish was the only viable option for a daily driver.

Big GrapheneOS fan here. Superb experience on a second hand pixel. Yes google might shut the gate one day but for the time being it's fine.

do you already know which hardware + OS combination you are going for?

Fairphone 6 with postmarketOS, most likely. TheMightyCat@ani.social is working on this port.

Ubuntu Touch is probably the better option, and with so much of SailfishOS still closed source, it is hard to put much trust in the medium term viability of that OS as the company clearly struggles to keep vital components up to date.

A post about switching from an Android phone to a Linux phone in a Linux phone community and you ask why it's not Android..? o.O
