Agreed, if I could have Sailfish on a Huawei P40 I'd be ecstatic. As it stands using Here maps, built in browser, and basic phone tools get me 90% of the way. I'm cheating a little in my transition -- I've moved my must use apps over to my iPad pro. 2FA, Instagram (a drug habit I hope to kick later in the summer), Keybase, mobile check deposit, etc.
I need to find a replacement for Google Keep (love how easy it is to move text/urls/photos between devices, jot down ideas / record thoughts) and Hangouts Dialer still.
