Moving apps to an SD card on Xiaomi devices can vary slightly depending on the model and the version of MIUI (Xiaomi's custom Android interface) you are using. Here’s a general guide to move apps to an SD card on a Xiaomi device:

1. Insert SD Card: Ensure your SD card is properly inserted into your Xiaomi device.

2. Open Settings: Go to the Settings app on your Xiaomi phone.

3. Navigate to Apps: Look for the "Apps" or "Applications" option in the Settings menu. This might be listed under "Apps" or "Installed apps" depending on your device and MIUI version.

4. Select App: Find the app you want to move to the SD card from the list of installed applications.

5. Storage & Cache: Tap on the app to open its details. Look for an option that says "Storage & cache" or similar.

6. Change Storage Location: Inside the Storage & cache menu for the app, you should see an option that allows you to change the storage location. If the app supports being moved to an SD card, there will typically be an option like "Storage location" or "Change storage".

7. Move App: Tap on "Storage location" or a similar option. If the app can be moved to the SD card, you will usually see an option to "Change" or "Move to SD card".

8. Confirm: Confirm any prompts that appear to finalize the move.

Please note:

• Not all apps can be moved to an SD card. Some apps, especially system apps or certain types of apps, may not support this feature.
• The menu names and options might vary slightly depending on your Xiaomi device model and the version of MIUI it is running.

If you encounter any issues or cannot find the option to move apps to the SD card, checking Xiaomi's support website or user manual specific to your device model can provide further guidance. Additionally, MIUI updates can sometimes change the location of options within the Settings menu, so ensure your device is running the latest software version available.
