I just switched to Notes, Reminders, Calendar and Mail it more polished option event hough i would love to use OneNote and other MS apps but not yet. In the mean time Samsung Notes will be my choice. Looks like Microsoft is working on the new version how we dont know when it will be out. its much easier to mutitask with it and do research. bottom like Samsung Notes more polished and well integrated into system. Im sure i can find more little quirks here and there. 5 - you cannot send/save a website from a browser to a particular Note that you already have going. 4 - if you using Samsung internet + Samsung Notes you can drag and drop text, images split screen, this doesn't work in OneNotes even with Edge Browser. (it works on the phone but not tablet version) 3 - no sticky notes integration - available on the phone for quick notes.

what is made me to switch away from it is 1 - when you using Physical Keyboard like Samsung Keyboard cover there is no spell check 2 - if you using s-pen you cannot select text with it only with your finger.

OneNote is OK for note taking if you have it on your phone that is pretty much what you gonna get. I have so many notes in One Note too however I slowly switched to Samsung Notes.
