Have you noticed that Viber stopped sending notifications about new messages, calls or groups on your Android smartphone? The problem may lie both in the settings of the messenger itself and in the system parameters of the phone - from energy saving mode to conflicts with other applications. In this article we will look at all possible reasonswhy notifications do not arrive to Viber on Android, and give step-by-step guide for each of them.

The peculiarity of the problem is that it is not always related to the messenger itself. For example, on Xiaomi, Samsung and Huawei smartphones, proprietary battery optimizers are often to blame for aggressively closing background processes. And on devices with Android 12+ new restrictions on notifications may work. We will look at solutions for all versions of the OS and popular brands.

  • 📞 Calls —a separate setting for incoming calls.
  • 👥 Groups and channels —if notifications do not come only from chats, check this section.

If some options are disabled, enable them and restart the application. Also pay attention to the item Exceptions —perhaps a specific chat or contact has been added to the list of ignored ones.

💡

In Viber there is a hidden “Silent mode” setting for individual chats. To check it, open the dialog → ⚙️ → “Notifications” and make sure that the “Mute” option is not activated.
