• Some of the most common reasons for online videos not playing on Android include: On your phone, you might be using an old version of YouTube. It's possible that the video you're seeing is corrupted or missing frames. It's possible that you don't have permission to see the video.
• If you've previously downloaded the video but can't play it on your Android phone, there are a few possibilities. The video's source could not be successfully downloaded. The video file's header could be missing or corrupted. There may be issues with the video or audio component's synchronisation.
• Videos may not play on the latest iPhone models if you're using an older version of iOS. Only updating your iPhone's operating system will address this problem.
