Clear Storage of Device

So, make sure you wipe out the items you no longer needed on your device and create some room so that the Gmail responds nicely and won’t be running slow anymore.

Update Gmail App

See what you can do if videos won’t play on your Android.

Why Are My Videos Not Playing On Android?

person recording cityscape using their android

Considering how most smartphone manufacturers tend to emphasize the unbelievable quality of their cameras, perfect night modes, seamless slow-motion recordings, superb resolution, and more, you’d expect all images and videos to function flawlessly on your Android. Unfortunately, that’s not always the case.

Occasionally, you could find that the videos you access from your gallery won’t play, sending you the message that “video cannot be played” or “can’t play video.” Other times, you might find that YouTube videos won’t load correctly or your downloaded videos won’t open in your media player.

There could be a wide variety of reasons that is happening, including:

  • Corrupted video
  • Corrupted SD card
  • Outdated media player
  • Outdated OS
  • Incomplete download from the source
  • Low storage
  • Video downloaded from a suspicious source

An array of hardware and software issues could lead to you being unable to play videos on your Android. However, that doesn’t mean you should immediately send your device for repairs or delete the videos that won’t play. There might be a few better solutions you could try.

1. Do a Factory Reset

person holding a black android

While a factory reset shouldn’t always be the first solution you go to, it can usually prove to be the most effective one.

A factory reset, aka a master reset or a hard reset, returns all your software configurations to the original state when the phone was first manufactured. In the process, all your data is lost – any photos and videos you have on your phone and the apps you’ve installed will be deleted. You’ll be logged out of all your accounts and won’t have access to your message history, contacts, and more.

While it seems like an extreme step, it can help fix any video issues you might encounter due to software bugs.

Though there could be slight variations between different phones, you can usually perform a factory reset by going to Settings > General Management > Reset > Factory data reset > Reset.

2. Restart Your Oppo A78 5G

While a factory reset is all but guaranteed to fix the issues you’re encountering with your videos, sometimes a simple restart might do the trick just fine. A restart works by clearing your RAM (Random Access Memory).

In a nutshell, RAM stores short-term data that helps your processor complete tasks quickly. This data is always easily accessible, and it’s what helps your phone quickly open webpages and apps you’ve recently used.

Over time, however, your RAM can get filled with unnecessary data and data fragments, which, in turn, can confuse your processor.

Restarting your phone will clear your RAM and potentially eliminate any data fragments causing your videos to be unplayable.

3. Check the Video Format

As a general rule of thumb, the videos you capture should be in a format your device supports. However, the videos you’ve downloaded might not be. That’s why checking the files’ video format before trying other possible fixes is in your best interest.

If the format isn’t supported, installing the right video player with the necessary compatibility is the most straightforward fix. Some of the most popular video players for Android include VLC for Android, GOM Player, MX Player, Bsplayer, and RealPlayer. You can easily find all of them in the Google Play Store.

4. Check the Internet Connection

If you’re having problems playing downloaded or online videos, check your internet connection to see if there’s an issue there. If your internet’s down, any downloaded videos might not have downloaded correctly, and any online videos that haven’t been loaded will not play.

Make sure that you turn the Airplane mode off and your Wi-Fi on. Check the connection and test your internet speed to see if everything works properly.

You might need a network reset if your phone can’t connect to a Wi-Fi network. The path might differ between Android devices, but you should be able to find the option for a network reset at the exact location of your factory reset. Go to Settings > General Management > Reset > Reset Network settings > Reset settings.

5. Clear the Cache

The cache stores a copy of your most commonly used data, helping decrease loading time and improve your phone’s performance. However, too much cache data can take up too much space and cause data corruption, preventing you from accessing some of your apps.

On average, you should clear your phone’s cache every few months to ensure that everything runs smoothly. If you encounter issues with your videos not playing on Android, clearing the cache could be just the fix you need.

To clear the cache from your apps, you’ll want to go to Settings > Apps. From there, select the app you want to remove the cache from, scroll down to Storage, then choose Clear Cache.

6. Update Android OS

An outdated Android OS is usually the culprit behind many bugs and glitches you may encounter on your phone. It can prevent you from playing video files, accessing apps, taking photos, and more. It can lead to data corruption and loss, expose you to malware and cyberattacks, and compromise phone performance.

Regularly updating your OS to its latest version is always in your best interest. It can solve the problem of your videos not playing and protect you and your sensitive data.

7. Repair Your Android OS

person holding a phone with black screen

You might already have the latest version of Android OS, but that still doesn’t mean your OS is functioning as it should. Maybe your phone was interrupted while downloading or installing the new OS version. Maybe your phone had underlying OS issues, or you accidentally downloaded files you shouldn’t have. Whatever the case is, if your videos don’t play due to an OS problem, you’ll need to repair your OS.

The best way to do it is with a reliable Android OS repair solution like Wondershare Dr.Fone.

Fast, efficient, and powerful, Wondershare Dr.Fone can repair your Oppo A78 5G in several simple steps:

8. Update the Video App

Sometimes, it’s not the outdated OS version causing issues but rather the out-of-date video app. Like OS updates, app and other software updates often contain fixes for common problems and security patches. Not every update is there simply to introduce new features.

To check whether you’re using the latest version of your video player, go to Settings > Apps. Find your video player app, tap it, and scroll down to the bottom of the page to see the version installed on your phone.

9. Clear Cookies and Browsing Data

If online videos are causing problems, not your recorded or downloaded ones, you might be due for a quick cookie and browsing data clearing.

Cookies are usually there to improve the user experience, allowing you to load websites faster and enjoy improved performance. However, if your cookies and browsing data occupy too much space, they could pose problems.

You’ll first need to launch your mobile browser to clear cookies and browsing data. If you’re using Google Chrome, the process is simple and streamlined. Tap the three dots in the upper right corner and go to Settings. From there, go to Privacy and security > Clear browsing data > Clear data.
