content: I have been using Onenote over the past two years on Windows laptop and Tab S4. Compare to the version on Windows the Android app is limited and restricted. Number one there is no ruler and syncing issues. Number two you cannot adjust the size of the page gridslines. Erasing function erase strokes does not do smooth erasing. Stylus support is alright however I wish there was more pen options and functionality. Overall app could have been better if it is similar to iPad or Windows.
