Any file attachments (photo, images, video, audio, text documents, e. s.) can be added to notes just by sending them from other applications which create or store media files, or from file managers. Photo and video can be added just from camera application, or from gallery by a click on button “Share” after marking selection. Any files accessible on device can be added by application option “Attach file” from a panel swiped from the left.
Adding photo and video is described in “Step by step” document under title “Six steps to add photo and video from photo gallery app..”.
