OneNote Beta for Android allows users to take notes right from the icon
This is one of those subtle updates that you might consider useless until the time comes when you really, really need it. While the previous update to the standard OneNote app now allows users to sign in using a phone number rather than a password (again, when you're in a rush to take a note, remembering your phone number might arguably be easier than trying to recall a password), the changelist for the new update is brief but important. It includes bug fixes and performance improvements, and you will need to press and hold the OneNote icon to quickly create different kinds of notes (Supported for Android version 7.0 and above).
If you are already a beta tester for the OneNote app, you can get the latest version from the Play Store. If you'd like to be a beta tester, check out the OneNote page at the Google Play Store to sign up.
