Transfer files from phone to samsung galaxy watch
From James's Wiki
This works for all file types by tricking the system to overcome the stupid built-in limitations
Transfer whatever file you want to end up on your watch to your phone. I do this by attaching said file to and email and emailing it to myself
find the file (probably in your downloads directory) using whatever file browser app you prefer on your phone. rename it to whatever.mp3
long press on it and select 'share'
select the 'Ware' icon (samsung galaxy wareable)
it should transfer
now on the watch:
open filemaster
find the file in the music folder and rename it back to txt
long press on it and select move
go into downloads/wsreader/ and paste
now you can open the file with the txt reader app
