Just moved my old 2013 Android mobile (#carbonrom.org) to a drawer of my desk.
The #Librem5 has now been my smartphone for over two month already and I didn't even touch the old phone.
Migration done.
Next step to replace all my Android usage: find a replacement for #osmand to run in an linux environment and get a tablet to run it.
In my opinion the screen of a smartphone is too small to use a map application. Navigation on ~5.x": yes, but planning of routes: no.
@chrichri
until we have #organicmaps on linux, you might try #osmin, the best navigation I found so far for linux phones.
