Could you potentially upload a movie you own to Facebook set to private if you wish to watch the movie on the go without using any data? (Providing you have unlimited social on the old plan) This means you can keep a few movies on the cloud and watch them at anytime using zero space/bandwidth on your phone.
I believe that is just for music. Many people complain about it. Google used to do it and now it just shows ads and gives a percentage to the artists.
Would it be an option to simply load the movie onto a spare memory card?
some phones dont have external storage? but im pretty sure facebook have upload limits on videos..
"If your account has been phone-verified the limit is 1,024MB and under 20 minutes."
so movie would be in about 5 parts.
I uploaded a home video I created to Facebook not long ago and it was automatically detected as violating copyright due to the backing music.
I'm not sure if they have the same kind of audio detection for movies though.
