The calendar on the Xiaomi phone does not open: reasons and ways of solving it

You try to open a calendar on your Xiaomi, but the app either doesn't start or closes right away? This problem occurs on devices in different series, from the budget Redmi Note to the flagship Xiaomi 14. The reasons can be both software (firmware failures, application conflicts) and hardware (damage to system files). In this article, we will analyze all possible scenarios and give specific instructions for troubleshooting.

It's important to understand that the MIUI calendar is closely integrated with system services, so its failure is often associated with deeper problems, such as a failure to sync with Google Account or damage to the application database. Don't rush to reset your phone to factory settings - in 90% of cases, the problem can be solved without radical measures.

1.Reboot the device and check for updates

Start with basic steps. Often the calendar stops opening because of a temporary MIUI failure, and rebooting the smartphone clears RAM and restarts system processes, which can restore the application to work.

How to properly reboot Xiaomi:

• 🔄 Press the power button for 3-5 seconds.
• 📱 In the menu that appears, select “Reboot” (not “Switch off»!).
• ⏳ Wait for full shutdown and automatic switching on (usually takes 20-30 seconds).

If the reboot didn't work, check for system updates. Newer versions of MIUI often fix bugs with system applications, including the calendar, and update only through a stable Wi-Fi connection:

1. Open Settings → About the phone → Update MIUI.
2. Click on "Check Updates."
3. If a new version is available, download it and install it.

2. Cleaning up cache and calendar data

Cache accumulation or application data corruption is one of the most common reasons why the calendar won't open. In MIUI, you can clear the cache without losing events, but resetting the data will remove all local reminders.

Cleaning instructions:

1. Go to Settings → Applications → Application Management.
2. Find the listing for Calendar (or Google Calendar if you use it).
3. Select "Storage» → «Clear the cache».
4. If the problem persists, click “Clear the data» (⚠️ All local events will be removed!).

Once the data is cleaned, the calendar will start as it was after the first installation, and if you sync events with your Google Account or Mi Account, they will automatically recover the next time you connect to the Internet.

Export events to the file (if there are important reminders)

Check sync with Google/Mi Account

Remember the password from the account for re-entry

Make sure your phone is at least 30% charged.

⚠️ Note: If you use an Exchange corporate account (for example, for work), cleaning calendar data may result in loss of access to work events. IT-How to restore synchronization.

3. Verification of synchronization with accounts

Xiaomi calendars may not open if you don’t have a connection to your Google Account or Mi Account, especially if you’ve recently changed your password, enabled two-factor authentication, or reinstalled your firmware.

How to check the synchronization:

1. Open Settings → Accounts and Synchronization.
2. Choose your Google Account (or Mi Account).
3. Make sure the switch opposite the Calendar is on.
4. Press "Sync" manually.

If the synchronization is not working:

• 🔑 Delete your account and add it again (in Settings) → Accounts click on the account → «Delete»).
• 📶 Check your internet connection (the calendar only syncs with a stable connection).
• 🛠️ Update Google Play Services in the Play Market.

Some Xiaomi models (such as the Redmi Note 11 Pro+) have a bug where the calendar doesn’t sync due to a conflict with energy saving settings.

1. Go to Settings → Battery and Performance → Application Power Management.
2. Find “Calendar” and select “No Limits”.

4. Reset application settings (without data loss)

If the calendar still doesn't open, but you don't want to reset your phone completely, try resetting all apps, which will bring back standard resolutions and settings for all programs, including system ones.

How to perform the reset:

1. Open Settings → System → Resetting settings.
2. Select “Resetting App Settings”.
3. Confirm the action (password or pattern lock may be required).

After discharge:

• 🔄 Reboot the phone.
• 📅 Try to open the calendar.
• 🔧 If necessary, reconfigure the calendar permissions (access to contacts, storage, etc.).

⚠️ Note: This method will reset all application settings, including saved browser passwords, individual permissions and notification settings!

5. Installation of an alternative calendar

If the standard MIUI calendar stubbornly doesn't open and resets don't help, a temporary solution is to install a third-party app, such as Google Calendar, Business Calendar or DigiCal.

Advantages of alternative calendars:

• 🔄 Automatic synchronization with Google Account.
• 🎨 More opportunities for customization (widgets, themes, reminders).
• 🛡️ Less dependence on system failures MIUI.

How to transfer events from the standard calendar:

1. Export events to the.ics file (if the calendar opens sometimes: Calendar settings → Import/Export).
2. Install a new app from the Play Market.
3. Import the.ics file to the new app.

On some MIUI firmware (e.g. Xiaomi.eu), the standard calendar may conflict with the Google Calendar.

• Turn off the standard calendar: Settings → Apps → Calendar → Disable.
• Use only the Google Calendar as your primary calendar.

💡

If you use Mi Account for sync, export events manually before switching to a third-party calendar. Not all apps support sync with your Xiaomi account.

6.Verification for viruses and conflicting applications

In rare cases, the calendar may not open due to malware or conflict with other programs (such as optimizers or antiviruses).

How to check your phone for viruses:

• 🛡️ Install antivirus (such as Malwarebytes or Dr.Web Light).
• 🔍 Run a deep scan.
• 🗑️ Remove detected threats.

Conflicting apps that can block the calendar:

If you suspect a particular application:

1. Launch your phone in Safe Mode (press the power button → “Safe Mode”).
2. Try opening the calendar. If it works, it's a problem in one of the apps installed.
3. Remove the recently installed programs until you find the culprit.

7. System Recovery through Recovery

If all previous methods failed, the radical solution is to restore the system through Recovery, which is suitable if the calendar stopped opening after a firmware update or an application failed to install.

⚠️ Warning: Recovery via Recovery will delete all user data if no backup was made.Use this method only as a last resort!

Instructions for Xiaomi:

1. Turn off the phone.
2. Press the Power button + Volume up to enter Recovery.
3. Choose a language (usually English or Chinese).
4. Go to Wipe & Reset → Wipe All Data.
5. Confirm the action (you will need to enter a password if it was set).
6. After reset, select Reboot → Reboot to System.

If the calendar still doesn't work after the reset, it could indicate a hardware fault in the memory controller or a partition damage, in which case a diagnosis is required at the service center.

💡

Resetting via Recovery is the last chance to return the phone to work without flashing it. If the problem remains, it is likely that the hardware part (for example, wear and tear of flash memory) is to blame not the software.

8.Apply to the Xiaomi Service Center

If none of these methods worked and the calendar still doesn’t open, contact the official Xiaomi service center.

• 📱 The phone fell or was subjected to mechanical stress.
• 🔋 After reset, errors appear when running other system applications.
• 🛠️ You suspect damage to internal memory (for example, your phone often overheats or brakes).

What to bring with you to the service:

• 📄 Checks or warranty card (if the phone is guaranteed).
• 🔐 Passwords from Mi Account and Google Account (required to unlock after repair).
• 📱 Backup of data (if possible).

The cost of diagnostics in official Xiaomi services is usually free, and repairs are covered by the manufacturer. If the warranty is over, check the prices in advance - sometimes it is cheaper to buy a new phone than to fix the old one (especially if the motherboard is the problem).

⚠️ Note: Do not contact informal workshops if the phone is on Mi Account protection. After repair, the device may be locked, and unlocking through Xiaomi will take up to 30 days.
