It seems that opening the keyboard now wakes up the screen (4.2.1.20, kernel from 20191223).

No, I do not see mine either (three distinct ext4 partitions, 128 GB total). I remember that SDs this size were an issue in Sailfish X too, maybe it is the same issue.

There is no common donation link for the three porters behind the port project unfortunately, but here is the link for TheKit. Would be cool to have those for Piggz and MisterMagister too.
