All instructions are based on Android 6.0.1. Due to the variety of versions of this OS, some functions or interface elements on your gadget may be different or missing. But the general principles for most Android devices are about the same.
Do not disturb mode
With this mode, you can quickly switch between different notification profiles. The first is called Total Silence, which is a completely silent profile. The second - "Only alarm clock" - as the name implies, skips only alarm signals. And within the third profile - "Only important" - you will hear both alarm sounds and notifications, but only from selected contacts and programs.
You can switch between sound profiles using special buttons on the notification panel. Depending on the version of Android, the panel contains either all three buttons with profile names, or one of them, and the rest appear after clicking on the first one.
Near the profile buttons, a link should be displayed to quickly navigate to the settings. By clicking on it, you can select contacts and other options for the "Only important" mode. In addition, in the settings you can set rules (start and end times, days of the week, etc.), according to which the system will switch profiles automatically.
Thus, the Do Not Disturb mode allows you to instantly adapt your smartphone to current circumstances. For example, you have started an important meeting - lower the notification panel, turn on the “Complete Silence” mode and calmly participate in the process. And with the rules you set up, the device itself will turn off notifications during working hours, and in free hours, on the contrary, it will turn on notifications.
Lock Screen Notifications feature
With this feature, you can customize how notifications appear on the lock screen. It is usually located in the notifications section of system settings.
The system offers a choice between three modes: "Show notifications in full", "Do not show notifications" and "Hide personal information". The names of the first two options speak for themselves. The latter means that the contents of received messages will not be displayed on the lock screen. Outsiders will only see an inscription like “new notification” and that’s it.
Turn off notifications on the lock screen or hide their personal information if you are afraid that someone else can read your correspondence.
Individual notification settings
The settings listed above are global, that is, they affect notifications from all installed programs.
But you can also manage notifications for each program individually. To do this, open the system settings and go to the notification section. There should be an item "App Notifications" or with a similar name. By clicking on it, you will see a list of all installed programs. By selecting any of them, you can customize its notifications.
The system allows you to block all notifications of the selected application, designate it as important, hide personal information and allow it to briefly display pop-up notifications for a moment on top of other programs.
As you can see, with the help of individual settings, you can, for example, block notifications from only the most annoying programs or remove the contents of the correspondence in the selected messenger from the lock screen.
In recent years, smartphones from the Chinese company Xiaomi have gained great popularity in Russia, a characteristic feature of which is the proprietary MIUI interface. It has a particularly deep system settings that are not available to users of standard versions of android.
However, despite the significant advantages, many complain that notifications do not come in xiaomi redmi note 3 - what is the reason for this and how to fix the problem is described below.
Why are notifications not coming to MIUI
Although MIUI seems to be a simple, user-friendly interface, it is fundamentally different from regular Android "and. MIUI developers have improved the autonomy of smartphones due to some restrictions on user applications (whatsapp, viber, vk, etc.). For example, prohibitions on background processes, network connections and geolocation significantly reduce the load on the CPU, thereby reducing battery consumption.The battery life is significantly extended.
However, because of this, an unfortunate drawback appeared. Users have noticed that xiaomi smartphones sometimes do not receive notifications from their favorite programs. Moreover, there are no notifications, even if the application was launched manually. And if the screen goes blank, then you can generally forget that social networks and other services should send important notifications.
Therefore, many are literally tormented by the question, why is everything so complicated and how to enable notifications in MIUI? For their sake, users are easily ready to sacrifice autonomy in order not to lose the necessary alerts. To solve this problem, it is necessary to carry out a comprehensive reconfiguration of MIUI, because. alas, there is no magic button "turn on notifications".
Background mode (power saving)
One of the deep customization items that you still need to try to find. Let's take the smartphone of our employee as an example, whose redmi note 3 pro no longer receives notifications. The name of the menu may differ depending on the build of MIUI, so trust your intuition and look for something similar in the settings: Advanced, Performance and battery, App power consumption. There will be several power saving modes, of which "Standard" is active by default. It is he who blocks access to network connections and geolocation. Naturally, in such a deaf offline application on xiaomi redmi cannot show any notifications at all. It is curious that in this mode, MIUI independently determines which background processes to block, so it is difficult to predict when certain notifications can arrive.
xiaomi redmi 3s power saving modes
If you found these settings, then you also encountered the problem of the lack of notifications in the "Standard" power saving mode. At this stage, there are 2 options.
- You can just turn off power saving. Then MIUI should start working like a regular Android, when the system kernel independently regulates all background processes, access rights, priorities, etc. Theoretically, all applications should have full access to background activity, the network, etc.
- Experienced users may do otherwise. Set the maximum power saving level ("High"), and then selectively unlock only important programs. Such a setting takes literally three minutes, but you can be sure that the resources of the smartphone will be allocated only to the processes that the user really needs. By the way, then you can also limit the background activity of Xiaomi system applications, which are unlikely to be very popular among domestic users.
Customizing Notification Types
Setting up background app activity was just the beginning of getting notifications back to normal. Few people know, but the MIUI interface also allows you to manage the types of notifications from applications.
Let's explain with the example of Facebook Messenger. The program can show message notifications in the curtain or change the indicator on its icon with the number of unread messages. However, a floating round window on the desktop is much more convenient. sometimes you cannot open the corresponding message from the curtain. If the phone has one type of notifications, but lacks another, then the problem is precisely in the limitation of these same types.
To fix this, you need to open "Notifications and calls" in the settings, and then find "App notifications". Next, there will be a list of applications that are allowed notifications. You can turn off unnecessary ones, and for the necessary programs, you can configure the types and priorities of notifications. It is here that the "Pop-up notifications" of applications are activated, as well as the normal transition from the curtain.
Application autostart
This is quite important, because sometimes the included autorun really affects the correct operation of some applications. You can configure automatic launch of programs during device boot through the menu "Permissions", "Autorun" in the "Security" section.
We go, and then set the desired parameters. It is advisable to set autorun for all important applications (social networks, instant messengers, etc.).
Pinning apps to RAM
This is a peculiar feature of the MIUI interface. Novice users will not immediately learn about it. The bottom line is that you can select applications that will always be in RAM, even if you “close all” through the menu of running applications. This is a very useful feature for fixing instant messengers, social networks (VKontakte) and dialers in the memory. Thanks to this, pinned applications open almost instantly, the MIUI interface will forcibly ensure their performance, protecting them from unexpected closing. After rebooting the smartphone, all "pinnings" still work.
To do this, in the menu of running programs, you need to “swipe” down the shortcut of the desired application (that is, the one where notifications fail) and click on the lock. A lock should appear on the shortcut, which means that the application is pinned to RAM. To unpin, simply swipe up on the shortcut.
RAM and WiFi optimization
In addition, in the Power Saving section of the battery settings menu, there may be an option to periodically clear the RAM. This feature removes unnecessary applications from the Redmi Note RAM, which allows you to speed up the device and reduce battery consumption, however, it is advisable to disable it in an unstable situation with notifications.
In the WiFi settings, it is also desirable to disable optimization, because when the screen is locked or turned off, the MIUI interface can be disconnected from wireless networks in parallel, again to save battery, but at the expense of user convenience.
We hope these tips will help you defeat the problem with notifications. Write in the comments what exactly helped you deal with this problem.

If WhatsApp notifications do not come, then some kind of device failure has occurred or its settings have been changed. We will tell you how to fix the problem on iPhone, Android, and Windows Phone, and also give separate instructions for Xiaomi and Meizu.
Checking and setting up the Internet
These instructions will work for most popular platforms. You may encounter slight differences in wording, but this will not affect the understanding of the process. A separate case if WhatsApp notifications on Windows Phone stopped coming: pay special attention to the quality of the Internet and to the item regarding the battery saver mode.
For owners of Xiaomi and Meizu smartphones
The devices of these companies are positioned as the most "long-playing", able to work for a long time without recharging. In fact, manufacturers are a little cunning: this advantage is not achieved due to the increased battery capacity. Task Manager blocks third-party applications from running in the background by default. As soon as you close the messenger, it is completely disabled and is offline. Accordingly, WhatsApp does not show message or incoming call notifications.
