If someone sends a music or video file for a blind user, Talkback announces its type that it is a music or video, but it doesn’t read anything for other file type like APK, PDF etc
1. Ask someone to send you an
PDF or APK files and music or video files.
2. Read them by TalkBack.
3. You will see that Talkback announces
the kind of files that were sent as a music or video file correctly, but it
doesn’t say anything for files that were PDF or APK.
