For the latest versions WhatsApp based on Android 10 (which is standard installed on Redmi 9) to work correctly, at least 200 MB of free space is required. If the memory is full of the cache of other applications, the system may generate errors when trying to write new files.

Compare the number you see with the data in the official store. If the difference is significant (for example, you have version 2.21, and the current version is 2.24), you may need to clear the cache before updating. Sometimes old temporary files conflict with new installation packages.
Before checking the version, clear the application cache through the phone settings: Settings → Applications → WhatsApp → Storage → Clear cache. This will not delete your conversations.

Setting up auto-update in MIUI
The shell MIUIinstalled on Redmi 9has its own application management settings, which may overlap Android system settings. To forget about the problem of updates forever, you should set up automatic mode.

Solving installation error problems
Sometimes the update process is interrupted in the middle or ends with an error code, for example Error 403 or Error 495. On smartphones Xiaomi this is often due to a full Google Play service cache.

Clearing the Google Play cache solves 90% of problems with downloading and updating applications on Android. Don't be afraid to use this feature.
Saving a backup before updating
Although updating the messenger rarely leads to data loss, there is a risk on devices with an unstable file system or when manually installing an APK. It's always better to play it safe and create a backup copy of your conversations.
WhatsApp on Android uses the cloud to store backup copies. Google Drive. Make sure that there is enough space on your disk and that the Google account linked to the phone is active.
Go to the messenger settings, select the section Chats and press Backup copy of chats. Press the button Create a copy and wait for the process to complete. The indicator will show the time of the last saved copy.
If you do not have access to the Internet or limited disk space, you can create a local copy. It will be saved to the phone’s internal memory in the folder WhatsApp/Databases. This file can be copied to your computer for reliability.
⚠️ Attention: If you switch from the regular version of WhatsApp to WhatsApp Business or vice versa, the backup copy may not be restored. Take this into account when changing the application type.
What to do if all chats are gone after the update?
Do not panic and do not create new chats. Uninstall the application completely, download it again, and when you launch it for the first time, agree to restore from a Google Drive backup. If the copy is local, make sure that the database file is in the correct folder before installation.
Is it possible to downgrade WhatsApp to an older version?
Technically, this is possible by installing an old APK file, but it is highly not recommended. WhatsApp servers may block the connection with older versions of the protocol, and you simply will not be able to send messages. In addition, new databases may be incompatible with old software.
Why is the update downloading very slowly on Redmi 9?
This may be due to speed limits in Xiaomi download settings or overloaded Google servers in your region. Try switching from Wi-Fi to mobile data or vice versa. Also check if the "Traffic Saving" mode is enabled in the network settings.
Do you need to delete the old version before installing the new one?
When updating via Google Play, you do not need to delete anything, the installation occurs on top. When manually installing an APK, the system usually prompts you to update the existing application. You only need to delete a version in case of critical errors or a change in the application signature (for example, switching from a modified version to the official one).
Does the update affect privacy settings?
Usually no, all settings are saved. However, after a major update, developers may reset some permissions or add new options to the privacy menu. It is recommended to check the "Privacy" section after the update to make sure that the "Been Online" status is hidden, if this was previously configured.
