The situation when the long-awaited video in Viber does not start or freezes on the loading screen is familiar to many smartphone users. This is annoying, especially if you are waiting for important information from colleagues or relatives. The problem can lie in a variety of factors: from a banal lack of Internet to conflicts in the system libraries of the media player.
In most cases, the situation can be corrected without a visit to the service center. Problems with playback often arises after an unsuccessful update of the firmware or the messenger itself. However, sometimes the culprit is an overflowing internal memory of the device, which does not allow the video stream to be buffered correctly.
In this article we will analyze in detail the main causes of the failure and offer step-by-step algorithms for eliminating them. You will learn how to properly configure network settings, clean up system junk and check codec compatibility to return multimedia functionality Viber to working condition.
Problems with the Internet connection and network settings
The first thing you should pay attention to is the stability of your connection to the global network. Video content requires significantly more bandwidth than text messages or voice notes. If the signal is weak, buffering it may be interrupted and the player will display a playback error.
Often the problem lies not in the lack of connection, but in the limitations set by the operator itself or the smartphone settings. For example, some tariff plans block video streaming when using mobile traffic, allowing it only through Wi-Fi. Check whether the traffic saving mode is activated in the system settings.
⚠️ Attention: If you are using a corporate Wi-Fi network, the administrator may have blocked the ports necessary for transmitting multimedia in instant messengers. Try switching to the mobile data to check.
You should also make sure that the “Flight” mode is not enabled on the device, which completely disables all radio modules. Sometimes a simple restart of the network interface helps: turn off the Internet for 10 seconds and turn it on again. This action causes the phone to re-request IP address from the router or cell tower.
Try opening any website in the browser. If pages load slowly, the problem is definitely in the communication channel, and not in the Viber application itself.
Cache and internal memory of the device are full
Messengers accumulate gigabytes of temporary files over time. Viber saves every image and video viewed in a hidden cache folder. When the free disk space runs out, the application cannot create a new temporary file to buffer the current video, which leads to freezing.
To solve the problem, you must manually clear the accumulated garbage. Go to the settings of your smartphone, find the “Applications” section and select Viber. In the data storage menu, you will see a “Clear cache” button. This procedure is safe and will not delete your correspondence or contacts.
- 🗑️ Free up space by deleting old unnecessary videos from the gallery.
- 📂 Check your downloads folder for duplicate files.
- 🔄 Reboot your device after cleaning to apply changes.
If clearing the cache did not help, the problem may be deeper. In some cases, a complete reset of the application data helps, but before that, be sure to make backup copy chats, otherwise the chat history will be lost forever.
Outdated version of the application and system conflicts
Developers Viber regularly release updates that correct compatibility errors with new versions Android. If you have an older version of the app installed, it may not work correctly with modern codecs or encryption protocols used by messenger servers.
Go to the application store Google Play or Galaxy Store and check for updates. If the Update button is active, be sure to follow this procedure. In rare cases, the automatic update may fail, in which case a complete reinstallation of the application will be required.
When reinstalling Make sure that the backup function in the settings Viber is enabled and the last save was made recently. After deleting and reinstalling, log into your account and restore data from the cloud.
⚠️ Attention: The settings menu interface may differ depending on the smartphone model (Samsung, Xiaomi, Pixel) and the Android shell version. Look for the “Applications” section in the general system settings.
☑️ Correct Viber update
Incorrect permissions and energy saving settings
Modern versions Android have aggressive energy saving systems that can “kill” background processes of instant messengers. If the system seems to be Viber consuming too many resources when downloading videos, it can forcefully stop the process.
You need to check the application permissions. Go to settings, select Viber and the “Permissions” section. Make sure that access to storage (files and media) is allowed. Without this right, the application will not physically be able to save the video stream to temporary memory for playback.
Also disable battery optimization specifically for this messenger. In the “Battery” section, find the list of applications and set Viber the mode to “Unlimited” or “No restrictions”. This will allow the video download process to work smoothly even when the screen is off.
| Settings | Recommended value | Where to find |
|---|---|---|
| File access | Allowed | Settings → Applications → Viber → Permissions |
| Battery optimization | Disabled / No restrictions | Settings → Battery → Optimization |
| Background data transfer | Enabled | Settings → Applications → Viber → Mobile data |
| Autostart | Allowed | Settings → Applications → Autorun |
Conflict between codecs and built-in video player
Sometimes the problem is not in the application itself, but in the system component responsible for video decoding. The built-in player Android may not support the specific format or bitrate of the video file sent by the interlocutor.
In such cases, the video may load completely (the progress indicator reaches 100%), but when you click on Play, the screen remains black or a format error message appears. This often happens when transmitting high-definition video 4K or with an unusual aspect ratio.
Try changing the video quality settings in itself Viber. Go to the messenger settings, “Data and multimedia” section, and try to reduce the quality of downloaded and played videos. This will reduce the load on decoder devices.
Secret solution for advanced users
If the built-in player is buggy, you can install a third-party video player (for example, VLC) and configure opening files through it by default, although Viber usually uses its internal engine.
Failures in the Android operating system
Global failures in the operating system can affect the operation of all applications at once. If the video does not open not only in Viber, but also in the browser or gallery, the problem is systemic. The system libraries may be damaged or an error occurred in the firmware update.
In this case, it is recommended to check for updates for the operating system itself. Go to Settings → About phone → System update. Installing the latest firmware often contains fixes for the security and stability of multimedia components.
If there is no update and the problem persists, you can try resetting the network settings to factory settings. This won't delete your personal files, but it will forget your Wi-Fi passwords and Bluetooth settings. To do this, use the path Settings → System → Reset settings → Reset Wi-Fi, mobile data and Bluetooth settings.
⚠️ Attention: Before performing a full phone reset (Hard Reset), be sure to save all important data to an external drive or to the cloud, as the phone will return to its factory state.
If none of the software methods helped, perhaps the problem is physical damage to the memory module or motherboard of the smartphone, which requires diagnostics in the service.
Frequently asked questions (FAQ)
Why does the video open for the interlocutor, but not for me?

The video takes forever to load, what should you do?
This is a sign of very low Internet speed or blocked download servers. Try switching from Wi-Fi to a mobile network (or vice versa), and also check if data saving mode is enabled in your phone settings.
Does antivirus affect video playback?
Yes, some aggressive antiviruses can scan the incoming video stream in real time and block it if they consider it suspicious. Try temporarily disabling the security software to check.
Why did the video stop working after updating Android?
The new version of the OS may have conflicts with the old version of the application. You need to update Viber to the latest version compatible with your current firmware, or clear application data.
