Moving apps to an external drive in Xiaomi smartphones is a challenge that users face when internal memory is scarce. Despite the limitations of Android’s latest versions (12-14), Redmi, POCO and Mi devices still have workarounds. The main problem is that the system blocks APK installation on removable media by default, and the standard “transfer to SD” feature is often missing or not working properly.
In this guide, we will discuss three current methods, from standard MIUI tools to manual transfer over ADB, and explain why some applications cannot be moved in principle. Separately, we will focus on the features of OTG-enabled flash drives and exFAT file system, which often cause crashes. If your Xiaomi does not see the drive or gives an error "Insufficient memory", you will find solutions in the last section.
1. Preparation of the flash drive: formatting and compatibility check
Before you port programs, make sure that your drive meets the requirements of MIUI. Xiaomi smartphones support flash drives up to 2 TB, but with reservations:
- 🔹 File system: only FAT32 (4GB file size or exFAT (for files) >4GB). NTFS not supported without root rights.
- 🔹 Recording speed: class UHS-I or U3 (Minimum Class 10 for stable application performance.
- 🔹 OTG-adapter: for devices without connector USB-C (Like Redmi. 9A) You will need a MicroUSB-OTG adapter.
To format the flash drive directly in the smartphone:
- Connect the drive through OTG and open the notice "USB-drive-in".
- Select Settings → Format as internal memory (if full integration is needed) or Format as portable (for temporary use).
- For exFAT, use third-party utilities such as SD Card Formatter (available on Google Play).
⚠️ Warning: Formatting as internal memory will bind the flash drive to the device, and once extracted, the data will not be available on other gadgets without completely erasing it.
Method 2: Transfer through MIUI settings (without root)
In MIUI 14 and later, the application portability function is hidden, but it can be activated through Storage Settings, which works for most user applications (e.g. Telegram, VK), but not system ones.
Instructions:
- Open Settings → Applications → Application Management.
- Select the desired application (such as Google Maps) and click Storage.
- If the Change option is available, tap it and select it. SD-map.
- Confirm the transfer. The process can take up to 5 minutes - do not remove the flash drive!
Limitations of the method:
- 🚫 It does not work for system applications (Camera, Gallery).
- 🚫 Some games, for example, PUBG Mobile) blocking the transfer due to protection against cheats.
- 🚫 After updating the application, it can automatically return to internal memory.
☑️ Preparation for transfer
Method 2: Manual movement APK-Files (for experienced files)
If standard portability is not available, you can manually copy the application.apk files onto a flash drive and then install them from there. This method requires access to the file system through Explorer or Total Commander.
Step-by-step:
- Install APK Extractor from Google Play and extract the APK of the desired application (the file will be saved in the ExtractedApks folder).
- Connect the flash drive and move the.apk to the Download folder or create a new one (like MyApps).
- Open Explorer, find the file on the flash drive and install it. When you request, select Install as an update (if the application has already been installed).
Important nuances:
- 📌 Application data (save, cache) will remain in internal memory.
- 📌 Some of them APK (For example, Netflix checks the signature and may not start after manual installation.
What to do if the APK is not installed?
Method 3: Transfer over ADB (for advanced users)
The Android Debug Bridge (ADB) tool allows you to force applications to move to a flash drive even if MIUI blocks it, requiring a PC and enabled USB debugging.
Algorithm of action:
- Activate Developer Mode: Settings → About Phone → MIUI Version (tap 7 times). Return to Settings → Additional → For Developers and enable USB Debugging.
- Connect your smartphone to your PC, install it ADB-Drivers (download from [the official Android site](https://developer.android.com/studio/releases/platform-tools)).
- Open the command line (Win + R → cmd) and type:
adb shell pm set-install-location 2This command will force the system to install new applications on the external drive by default. To transfer an already installed application (such as WhatsApp), use:
adb shell pm move-package com.whatsapp /storage/1234-5678Where /storage/1234-5678 is the path to your flash drive (you can find it through the adb shell ls /storage command).
⚠️ Note: Some applications (e.g. Google Play Services) may cause system failures when forced to transfer. Before experimenting, back up through Settings → System system → Backup.
5. Compatibility table: which applications can be ported
Not all programs support external media, and the table below shows the popular apps tested on the Xiaomi Redmi Note 12 and POCO X5 Pro (MIUI 14, Android 13):
| Annex | Transfer through MIUI settings | Handheld APK transfer | Transfer through ADB | Notes |
|---|---|---|---|---|
| Telegram | ✅ Yes. | ✅ Yes. | ✅ Yes. | Chat data will remain in internal memory |
| VK | ✅ Yes. | ✅ Yes. | ✅ Yes. | Music and video are cached on a flash drive |
| Google Maps | ❌ No. | ✅ Yes. | ✅ Yes. | Offline cards are stored only in internal memory. |
| PUBG Mobile | ❌ No. | ❌ No. | ⚠️ Partially. | The game blocks the transfer because of anticheat |
| Spotify | ✅ Yes. | ✅ Yes. | ✅ Yes. | Downloaded music is carried along with APK |
💡
Forced transfer of system applications (such as Camera or Gallery) through ADB can result in a cyclical smartphone reboot, and the risk is particularly high on devices with MIUIs below version 12.5.
6. Solving errors in transfer
If there are any problems during the transfer, check the following points:
- 🔌 "USB-Driver not identified: Try another OTG-cable or adapter. on some Xiaomi models (e.g. Redmi) 10C) Requires an original adapter.
- 📛 "Not enough space on the device": Delete the app cache through Settings → Warehouse → Clear the cache.
- 🔄 "App not ported": Reboot your smartphone and try again. If the error repeats, check the flash drive for errors via PC (Chkdsk D command: /f into CMD).
- 🚫 "Transfer is not available": the application can be protected from modifications (for example, bank clients such as SberBank Online).
To diagnose flash drive problems, use the A1 SD Bench app (tests read/write speed) or SD Insight app (verifies drive authenticity). If the write speed is below 10 MB/s, the applications will slow down.
💡
If the application is slow to work after the transfer, try turning off animation in MIUI: go to Settings → About Phone → MIUI version (stamp 7 times), then to For Developers → The scale of the animation window and select No animation.
7.Alternative solutions: cloud storage and memory optimization
If transferring to a flash drive is impossible or ineffective, consider alternatives:
- ☁️ Cloud services: Mi Cloud (5GB free), Google Drive or Yandex Disk for app backups (use Swift Backup for backup) APK + data).
- 🗑️ Cache Clearing: Apps like Facebook or Instagram can take up to 1-2 GB cache. Clean it weekly through Settings → Annexes → Warehouse.
- 🔄 Lite versions of applications: Replace "heavy" programs with lightweight ones (for example, Facebook Lite, Messenger Lite).
- 📱 Memory Extension: Some Xiaomi models (e.g. Redmi Note 11 Pro)+) supported by virtual RAM — Use the free space on the flash drive to increase RAM (Settings) → Additionally. → Expansion of memory).
For automatic optimization, install Files by Google – the application analyzes unnecessary files (duplicates, old screenshots) and suggests removing them.
