Part 1: Why Can’t I Play YouTube Video After Downing?

If you’re having trouble playing YouTube videos from your mobile device after downloading them, it could be happening for a number of reasons. You can check some reasons below before turn to get the solutions.

  • Your internet, WiFi, or cellular network connection could be broken or moving incredibly slow.
  • The YouTube app could be causing an issue in the background with the video, making for a poor quality download.
  • The video format that was initially uploaded does not match what is playable on your device.

Part 2: Solutions for YouTube Video Cannot Play

We put together a quick list of the most uncomplicated repairs for YouTube download issues and video playback errors. Each one only requires a basic understanding of technology, so even if you are slightly apprehensive about a tech fix, we’ve got you covered!

01 Try to Re-Download the Video Again

Start by downloading the original video once again. Just re-download the file using the same method as before. You can also try downloading from a browser on your phone instead of the YouTube application, and that may get around the problem as well.

02 Ensure the Video Downloaded Completely

If the internet connection is not stable or slow, the video may be interrupted while downloading. So use a faster and more stable method to download YouTube videos.

Just move your physical location closer to a stronger WiFi signal or where your cellular connection has more bars and is speedy.

03 Check the Video Format and Whether it Matches with the Player

The YouTube video could have been uploaded in a format that your phone does not want to playback after downloading. This could be if the file uses MKV formatting instead of MP4, like most videos uploaded by YouTube users. You can get around this by downloading a different video player like VLC Media Player from the app store.

04 Update YouTube App on Your Android Device

It is a common reason why YouTube downloaded videos not playing on your phone. Whenever your YouTube application is out of date, it cannot operate correctly with the vast amounts of media hosted on its service. Or, it cannot communicate clearly with your phone because there is a glitch in the background, causing some conflict. A quick update should solve either of these issues.

  • Go to the Google Play Store on your Android device. Then search for?YouTube?and tap on the app when it appears in the list of results.
  • Tap Update > Install.
  • If there are no updates available, you will not see an option to install anything.

05 Clear the Cache in YouTube App

Sometimes data gets “stuck” inside of an older Android device. All that needs to happen is you should essentially “sweep the dust” out of your app by clearing the cache. This will free up operating space, so it works more efficiently.
