How Do I remove video playback on my iPhone 7 completely? Hi I want to completely disable the ability to play videos on my iPhone. I don't mind jailbreaking the phone to change some core settings if this is the solution. I'm not just not sure what to change. Thank you. 

iPhone 7 OS 12.
Turn on Screen Time in Settings and you could allow the apps you want or need and keep the ones you don't want out. 
Also in Screen Time settings under Content &amp; Privacy Restrictions you can turn off or restrick settings. You can choose to not allow apps. You can choose Don't allow Movies and scroll down to the bottom and turn off Show movies in the Cloud.
