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:
Launch the Settings app from the Home screen of your iPhone or iPad.
Scroll down and tap on Facebook.
Now tap on Settings.
Under the Video section, turn On the option for Auto-play on WiFi only.
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!
