Owners of Xiaomi, Redmi and Poco smartphones often face a situation where the usual widget with dates suddenly disappears from the desktop or stops displaying important meetings. This is not a system bug, but most often the result of accidental removal, resetting or features of the MIUI and HyperOS shell. Understanding where exactly the interface element could go allows you to quickly return functionality without complex manipulations.
The Android system is designed so that standard applications are rarely removed completely without explicit user action, but their shortcuts may be hidden. The launcher (desktop shell) could be updated, which led to resetting the widgets, and the problem may lie in the display settings of system applications, which are sometimes hidden after cleaning memory or optimization.
In this article, we'll go into all the possible calendar disappearance scenarios, learn not only to return icons to their place, but also to adjust the synchronization of events so that no meeting is lost again. 90% of the time, the problem is solved by simply adding a widget through the desktop editing menu, which many users forget.
Search for a standard Calendar application in the system
The first thing to do when a shaomi calendar is missing is to make sure that the app itself has not been removed or hidden from the shared list. Often users accidentally drag the icon into the games folder or remove the shortcut, thinking it's just a widget, not a program. To check, open the menu of all apps by swiping your finger from the bottom up on your desktop or clicking the appropriate navigation button.
In the list that opens, use the search bar at the top of the screen and type in the word "Calendar." If the app is installed, it will appear in the results. Notice the icon: in MIUI shells, it's usually a red square with a white numeral. If the search didn't yield anything, it may have been removed and you'll need to download it again through the GetApps store or Google Play.
It's also worth checking the Tools or System folder, where the launcher automatically sorts standard utilities. Sometimes after a system update, all system widgets and applications are grouped again, and the calendar may be in an unexpected place. If you find an application that doesn't open or doesn't work correctly, try clearing its cache.
- 🔍 Go to the menu of all applications and use the search by name.
- 📂 Check the system folders "Tools", "Google" or "Systems".
- 🗑️ Make sure the app is not removed along with the shortcut.
- 🔄 If the application is found but does not work, clear the data in the settings.
It's important to distinguish between the app itself and the widget. The app is the program that stores data, and the widget is the graphical element on the desktop. Deleting the widget doesn't delete the app, but it deprives you of quick access to dates. If the app is found on the menu but it's not on the desktop, go to the next section of the instruction.
Restore the widget on the desktop
The most common reason for “disappearance” is to remove the widget from the desktop, and to return it, you need to go to screen editing mode, for this purpose, on most Xiaomi devices, you need to pinch two fingers (mix them together) in a free space of the screen or hold your finger on an empty area for a long time.
There are a few options on the bottom menu, and you can select "Widgets" from the list that opens, and you can find the "Calendar" section, which can be a standard MIUI calendar, a Google calendar, or third-party widgets if you've installed them before, and you can select the option you want and drag it to the free screen space.
☑️ Checking widget recovery
If the Google Calendar widget doesn't appear on the list of available ones, make sure that the Google app is installed and updated. In some cases, the widget may be hidden due to the limitations of the theme. If you're using a third-party theme, try switching to the standard "No Limits" or "Classic" theme in the settings to see if the widget appears.
⚠️ Note: If the calendar widget is not added or disappears immediately after adding, it may indicate a lack of RAM or conflict with the installed launcher.
Once you have the widget on the screen, click outside the widget to exit editing mode. Now the dates should be visible. If the widget is displayed but the data is not updated, you will need to check the sync settings and permissions for the application.
Configure event display and synchronize
Sometimes the calendar is still there, but it's empty or it doesn't show events. It's an account sync problem. Android allows you to keep multiple calendars at once: local, Google, Exchange, or others. If the desired account is disabled in the display settings, the events will not be visible.
Open the Calendar app and click on the three dots or menus in the corner of the screen. Select Settings or Calendar Management. Here you will see a list of all connected accs. Make sure the switch opposite your main mailbox (like Gmail) is activated. Also check if the tick is ticked.
To keep synchronization running, you need to check the battery settings. MIUI aggressively saves charge and can stop the calendar's background synchronization. Go to Settings → Apps → All Apps → Calendar → Battery and select No Limits mode, which ensures that the system doesn't "kill" the schedule update process.
- 📅 Open the settings inside the Calendar app.
- ✅ Check the sync activation for the desired Google account.
- 🔋 Set the battery mode "No restrictions" for the calendar.
- 🔄 Manually update the schedule by pulling the list down.
If events occur but are delayed, try clearing the cache of Google Play Services. Often, this system component is responsible for transferring data between Google servers and your device. Rebooting your smartphone after changing your sync settings also helps you apply the changes correctly.
Why are there no notifications of events?
Problems with access rights and permits
Modern versions of Android and HyperOS are very privacy-friendly, and if Calendar isn’t given permission to access contacts or storage, it may not work properly or display birthdays from the address book, which is a common reason why users think the calendar is broken.
Go to Settings → Apps → All apps. Search Calendar and click App Permissions. Contacts, phone (birthday) and storage should be activated here. Without contact permission, the calendar will not be able to pull up your friends' birthdays, even if Google sync is enabled.
| Type of permit | Why? | Recommended status |
|---|---|---|
| Contacts | Birthday display | Permission. |
| Warehouse | Maintaining schedule and export | Permission. |
| Notifications | Meet-up reminders | Permission. |
| Auto-start | Background work | Turn on |
You should pay special attention to auto-run. Xiaomi phone has a separate application "Security", where in the section "Permissions" → "Out-run" you need to find the Calendar and turn it on, which will allow the application to start immediately after you turn on the phone and promptly remind you of events, even if you have not opened the calendar in a long time.
⚠️ Warning: Once the firmware update is updated, permission settings may reset to factory. Always check access rights after a major system update.
If all permissions are given but the problem persists, try deleting and adding a Google account again. Go to Settings → Accounts and Sync → Google, select your account and click Delete. Then add it again, entering your login and password. This will force you to start full sync of all data.
Third-party alternatives and widgets
If the standard MIUI calendar seems uncomfortable or continues to malfunction, you can always use third-party solutions.The Google Play store offers many great alternatives that often have more flexible design and functionality. Popular options include Business Calendar 2, DigiCal or SolCalendar.
Third-party calendars are often better integrated with other services, such as tasks from Trello or Todoist. When installing such an application, the system itself will suggest replacing the default calendar. Third-party widgets are usually more informative: they can show the weather, moon phases and task list directly on the home screen.
💡
Use third-party calendar widgets if you don’t like standard MIUI design, and they often support deeper customization of fonts and colors, allowing you to fit the calendar perfectly into any theme.
However, it is worth remembering that setting multiple calendars can lead to duplication of events. To avoid this, the settings of each calendar (both system and third-party) need to carefully filter the accounts displayed. Keep only one event source active for each schedule type.
When choosing an alternative, pay attention to the reviews and date of the last update of the application. For Xiaomi devices, it is important that the widget is optimized to work with an aggressive energy saving system, otherwise it may stop updating in the background, as well as the standard application.
Frequent mistakes and their solution
Even after all the settings, there can be specific errors, such as a calendar showing the wrong date or time, and this is solved by checking the date and time settings in the system: make sure you check the "Use Network Time" box and select the right time zone. Wrong time zone is a common cause of bias of events by an hour or two.
Another problem is the phone-computer desynchronization, and if you add an event on your PC and you don't, check the Internet connection, sometimes it helps to turn on and off flight mode to reboot network modules, and it's also worth checking if your Google account storage is full (15GB limit), because when it's exhausted, sync stops.
If nothing works, you can reset your Google App settings. Go to Settings → Apps → All Apps → Google Play Services → Memory and click Clear All Data. Don’t worry, it won’t delete your personal files, but it will reset your sync settings, which often resolves complex software conflicts.
- 🕒 Check the automatic date and time setting over the network.
- 🌐 Make sure you have a stable internet connection for synchronization.
- 💾 Check the free space in your Google account.
- 🛠️ Clean up Google Play data for persistent errors.
⚠️ Note: Google Play data cleanup may temporarily disrupt other apps that depend on your Google account, and it will take several minutes to background check services after the procedure.
In rare cases, the problem may be caused by damage to system files after a failed update. If the calendar crashes immediately at launch (black screen or instant closure), try updating the app through the GetApps store or Google Play. If it is a system application that cannot be updated, only a full factory reset will help, but this is the last resort.
💡
Most calendar problems on Xiaomi are solved by checking the synchronization of the Google account and allowing the application to auto-run in the MIUI security settings.
