Some people don't like when videos auto-play as they scroll past them. Back when Instagram started doing this, I had a feeling Facebook and other social networks wouldn't be far behind and I was right. While Facebook doesn't let you completely disable auto-play for videos, you can at least stop it if you're using cellular data instead of WiFi. Here's how:
That's all there is to it. At least this can stop Facebook for iOS from eating your data in order to auto-play videos.
Do you like the auto-play feature for videos, even if they're muted by default? I personally don't as I feel it's very distracting when scrolling. I'm interested to know how you guys feel about it too so let me know in the comments!
