I transferred a odt file created in LibreWrite on a Linux based system to my Samsung Galaxy Tab A. The file is password protected. File is not corrupted. LibreOffice Viewer is installed on Tablet. When I try to access it I never get prompted for the password. Tablet gives a black screen with a small blue arrow rotating in a circle. OpenDocument Reader doesn’t access the file either.
Have you tried opening the document first on your PC and then tacking out the passwor protection ?
