Owners of smartphones based on Android often encounter incomprehensible visual artifacts in popular educational applications. One of these mysterious phenomena is the appearance of the number “2” on the icon or in the interface of an electronic diary, for example, in systems Dnevnik.ru, MASH or Network City. This symbol can be confusing, especially if it does not disappear after rebooting the device.
In fact, this “two” is most often a notification counter (badge), which signals the that the user has two unread messages, two new grades, or two required homework assignments. However, in rare cases, this may be a software failure of the application itself, when the counter is “stuck” and displays incorrect information even after reading all the notifications.
In this article, we will look in detail at why this problem occurs and how to forcefully remove the annoying number from the screen of your smartphone. We will consider both standard cleaning methods through the settings of the application itself, and radical methods of resetting data, which are guaranteed to return the icon to its original appearance.
The nature of the appearance of numbers and notification counters
Modern operating systems, including Android, use a system of badges (icons) to inform the user about events without having to open the application. The number “2” on the diary icon is the standard operating mechanism of the launcher or the application itself. It counts the number of active events in the user's database.
Most often, this figure means specific actions that require the attention of a parent or student. These could be new assessments that have not yet been reviewed in detail, or comments from teachers on completed work. Sometimes the system also takes into account technical notifications, for example, about changing the schedule or canceling a lesson.
It is important to understand that the interface electronic diary is synchronized with the server of the educational institution. If there are two unread events on the server, the application will persistently display this fact. The problem occurs when the user has read everything, but the visual indicator has not been updated due to desynchronization of the local cache.
⚠️ Attention: If the number "2" is displayed in red and blinking, this is a priority notification. Make sure that this is not an urgent message from the school administration or class teacher before trying to hide it using technical methods.
Checking internal application notifications
The first and most logical step is to check the content of the application itself. You need to go to electronic diary and carefully study all sections. Often, users view only ratings, forgetting about the tab with messages or announcements.
Open the application and go to the section, which is usually indicated by a bell or envelope icon. There may be two system messages hidden here. Also check the "Homework" section, as some versions of the apps mark work that has not been checked by the teacher as requiring attention.
If you find unread messages, open each of them. In some cases, you need to not only open the message, but also click the “Confirm Read” button or scroll the text to the very end for the trigger to work correctly. After that, return to the main screen and check if the number has disappeared.
- 🔍 Check the "Ratings" tab and open each new rating in detail.
- 📩 Go to the "Messages" or "Chat" section and read all the dialogues.
- 📅 Check the "Schedule" section for availability changes marked with an update icon.
Sometimes simple manipulation of the notification filter helps. Try sorting messages by date or read status. This will identify hidden notifications that are not displayed in the general list due to privacy settings or filters.
If you have read all the messages, but the number remains, try logging out of your account in the application and logging in again. This will forcefully update the status of all notifications from the server.
Clearing cache and application data
If the internal check did not help, then the problem lies in the local application files. The smartphone cache may have stored the counter in an outdated state. To correct the situation, you need to clear the cache through the system settings. Go to Android.
Go to Settings your smartphone, then select the section Applications or All applications. Find your electronic diary in the list (for example, Dnevnik.ru). Click on the name of the application to open the information page about it.
In the application menu, find the item Storage or Memory. Here you will see two buttons: "Clear cache" and "Clear data". Start by clearing your cache. This is a secure operation that will not delete your logins and passwords, but will reset temporary files, including the erroneous notification counter.
Settings → Applications → [Your Diary] → Storage → Clear cacheIf clearing the cache does not work, you will have to use a more radical method - clearing data. Attention: this operation will reset the application to its factory state. You will have to re-enter the login and password for the electronic diary, as well as set up notifications.
☑️ Algorithm for completely resetting the application
Notification settings in the Android system
Sometimes the problem is not in the application itself, but in the way the operating system Android handles notification icons. In different firmware versions (MIUI, OneUI, ColorOS), the settings may differ, but the general principle is the same.
Go to the notification settings for a specific application. In this menu you can find the "Notification Badge" or "Badges" toggle. Try turning this feature off, wait a few seconds, and then turn it back on. This action will force the system to recalculate the current number of events.
It is also worth checking the settings of the launcher (desktop shell). Some third-party launchers have their own settings for displaying counters. If you are using a standard launcher, check the home screen settings in the general phone settings menu.
| Action | Where to find | Result |
|---|---|---|
| Disable badges | Settings → Notifications → Icons | The number will disappear, but new events will not be displayed on the icon |
| Reset application settings | Settings → Applications → Reset | Complete removal of all local data and settings |
| Restart the launcher | Settings → Applications → Launcher → Stop | Updating all icons on the desktop |
Do not forget that after changing notification settings, you may need to restart your smartphone for the changes to take full effect. This is especially true for devices with a heavy graphical interface.
What to do if the clear buttons are inactive?
If the "Clear cache" or "Clear data" buttons are not pressed (gray), the application may have device administrator rights. Go to Settings → Security → Device administrators and uncheck the diary application.
Reinstalling the application as a last resort
In cases where neither clearing the cache nor manipulating the settings helps remove the number "2", the only reliable way remains is to completely reinstall the application. This ensures that all corrupted configuration files are removed.
Remove the application from the device by holding the icon and selecting "Delete". After this, it is recommended to reboot the phone to free up system resources and delete remaining files from temporary directories.
Then go to the official application store Google Play or RuStore (depending on your phone model and region) and download the latest version of the electronic diary. When you first start, enter your credentials.
- 🗑️ Completely remove the old application from the device.
- 🔄 Reboot your smartphone to clear the RAM.
- 📥 Download the latest version of the application from an official source.
A fresh installation will automatically pull up the latest data from the server, and the notification counter will be generated anew, based on the real state of affairs. If the number "2" appears again immediately after logging in, it means that you actually have two unread events on the server.
⚠️ Attention: Before deleting the application, make sure that you remember your login and password. Restoring access to some electronic diary systems may take time and require contacting the school.
Specifics of different diary platforms
Different platforms of electronic diaries have their own features of working with notifications. For example, in the MASH (Moscow Electronic School) system, a number can mean the number of mandatory tests that need to be passed. In Dnevnik.ru these are most often new ratings or comments.
In the system Network City. Education the counter can respond to changes in the call or office schedule. It is important to know the specifics of the platform your school uses in order to correctly interpret the application signals.
Some applications allow you to flexibly configure the types of notifications. Go to the settings inside the diary itself and disable those types of events that are not critical for you. This will reduce the likelihood of extra numbers appearing on the icon in the future.
Completely reinstalling the application is a 100% way to remove the visual bug, but it requires re-authorization and customizing notifications.
It is also worth considering that developers periodically release updates that correct such bugs. If the problem is widespread, you should check for updates in the app store. Perhaps the new version already solves the problem with "sticking" counters.
Frequently asked questions (FAQ)
Why does the number 2 not disappear after reading all the messages?
This happens due to the desynchronization of the local application cache with the server. The system did not receive a signal that the message was read. Clearing the application cache or logging into your account again helps.
Is it safe to click “Clear data” for an electronic diary?
Yes, it is safe for your personal data, since it is stored on the school server. However, you will lose your local application settings and will be forced to re-enter your username and password.
Can the number 2 mean a virus or system error?
In 99% of cases, this is the standard notification counter. Viruses rarely behave this way in specific applications. If after reinstalling the application the number behaves strangely (changes on its own), you should check your phone with an antivirus.
What should I do if I forgot my password after resetting the data?
Use the "Recover Password" function on the login screen. This usually requires access to the associated email or phone number. As a last resort, contact your class teacher for help in restoring access.
Does the Android version affect the display of notification icons?
Yes, in Android versions 8.0 and later, the notification channel system works differently than in older versions. Badge display settings can be located in different sections of the menu depending on the manufacturer's shell (Samsung, Xiaomi, etc.).
