On Android, share images and videos to Facebook from the Boards app, then add your caption with the Boards Keyboard.
Why not the keyboard?
Android doesn't let keyboards insert images into Facebook and other social apps. If you try, you'll see "Content not supported." This is an Android limitation that Boards can't change.
Share an image or video
- Open the image or video in the Boards app.
- Tap the share icon. For a video, tap Share file and wait for it to reach 100%.
- Select Facebook.
- Tap the caption field and switch to your Boards Keyboard.
- Tap your Text script to add your caption, then post.
Text only?
Open Facebook, tap the post field, switch to your Boards Keyboard, and tap your script.
Want to schedule it?
Save the image to your phone first, then upload it in Facebook's scheduler. See Saving Images and Videos to Your Phone.
