I'm a beginner with rooting, flashing and so on, but I'd like to try to flash Lineage OS 14.1 on my Samsung Galaxy Note 8 (GT-N5100). However I often use S Note for taking notes using the S Pen. Does anybody know if it is possible to somehow get and reinstall the S Note App after flashing the new OS? If yes, how?
S Note is tightly integrated with Samsung's framework and thus can't be ported to non-stock-based ROMs.
In the meantime, try Squid as an alternative. Lots of available pre-defined notes, export to PDF, and best of all it makes use of the spare button on the pen that LineageOS doesn't use.
