Watching videos on Facebook has become a familiar entertainment activity for many users. However, spontaneous video errors can make the usage experience frustrating and disruptive. In the article below, Antidetect Browser Hidemium will analyze the reasons why Facebook videos don't run automatically and guide you through 4 effective, easy-to-implement solutions right on your phone or computer.
1. Reasons why Facebook videos do not automatically play
Videos on Facebook that don't run automatically usually come from the following reasons:
Weak or unstable Internet connection: When the network speed is slow or unstable, Facebook will automatically suspend the automatic video playback function to reduce data consumption.
Power saving mode is on: Many mobile devices have a power saving mode, which limits features like video autoplay to save system resources.
Facebook app is buggy or outdated: If you're using an outdated version of Facebook, some features may not work correctly.
Autoplay option has been disabled: Some users accidentally or intentionally turned off the video autoplay function in settings, resulting in videos not playing automatically.

2. How to fix Facebook video error not running automatically
Here are 4 simple steps to help you handle this situation quickly:
2.1 Check Internet connection
First, make sure your device is connected to stable Wi-Fi or has enough mobile data. A slow connection or network outage will cause Facebook to temporarily stop playing videos to save bandwidth.
2.2 Turn off battery saving mode
Battery saving mode may limit app background activity. You should access the battery settings on your device and switch back to normal usage mode. This helps Facebook and other apps work smoother, including video autoplay.
2.3 Update Facebook app
Old application versions often contain errors and are not optimized. You should go to the App Store (for iPhone) or Google Play Store (for Android) to update Facebook to the latest version. Updating not only improves performance but also helps fix errors like videos not playing automatically.
2.4 Check and re-enable the video autoplay feature
Go to Settings & privacy > Settings > Media and contacts > Autoplay and make sure this option is turned on.
