lesser version
One might take the view that the Samsung 9’s got stuck at Oreo because of this very difficulty of the Upgrade to Android 10, Q.
As “stable” appears right now to have gone unstable, I am guessing that only a robust fix could restore stable … so perhaps this explains the delay. I am in no way qualified to speak for the /e/ team.
if you decided to go for a reinstall without /e/ team support, I guess you would need to convince yourself that you felt dev is not the lesser choice today !
