Does anyone have any feedback on how the s note to Evernote sync works? Just one way, or does Evernote updates sync back to s note?
I'm sorry, but I can't answer for how the Evernote sync works. But what you are asking about is accomplished using the Samsung sync process. In fact, when you import and export notes using s-note your folders and sub-folders stay in tack. Previously I owned the original Note phone, later the Note 10.1 (2012), and then the Note 2. Now that I have the Note 3, and Note 10.1 (2014) I was able to set up my phone and tablet and have the notes import in with no problem and pick up editing right where I left off.
I like to use the Samsung cloud service because no matter which device I'm using I know my notes are always in sync (backward and forward).
If there is a downside, and I'm not sure it's really a downside, to this functionality, is that I am tied to s-notes, and by default Samsung. If you sync your notes with Evernote. Dropbox, or Google Drive, then at least you can keep your notes outside of the Samsung line of products.
