Twitter Introduces Autoplay Videos, Here’s How to Turn Them Off
Twitter’s autoplay feature allows you to automatically play ads, vines and videos as you scroll through the timeline. It’s turned on by default, but luckily you can turn it off.
Where you disable it depends on your OS. Autoplay should only happen on official Twitter apps:
On Android :
Tap the three-dot menu icon in the upper-right corner, then go to Settings> General> Autoplay Videos and select Never Autoplay Videos.
On iOS :
Go to Settings> Autoplay Videos and click Never Autoplay Videos.
On the desktop :
Go to the settings page , select “Account” and make sure the “Autoplay video” checkbox is unchecked.
