How to spot folder of some application on Android (Galaxy Note 5)? I intend to reset my phone to get rid of bad applications. I will reinstall all applications wanted, but there is the notes application I use that I want to get the data of (no option to back up notes)... how do I get the data?

the application is called Notes by programmer "Office"
The application, Notes by Microsoft, stores your entries on OneDrive, they are not stored locally on your mobile device. This also means that your notes are always backed up.

If you remove the Notes application from your mobile device, you will have to log back into it when after you reinstall.
