absent or selectively operating

Why is that happening? It's Google's policy and MIUI's limitations. Since Android 6.0, porting apps to SD has become partially blocked due to performance and security issues. However, there are workarounds, both official and hidden. In this article, we'll go through all the working methods for Redmi 9A, including porting through settings, ADB, and alternative solutions for freeing memory.

If you’ve tried porting apps before and you’ve encountered the error “Premote button is inactive” or “App does not support porting,” don’t despair. We’ve tested each method on Redmi 9A with MIUI 12-14 and are ready to share the results.

Why on Redmi? 9A You cannot transfer all applications to SD-map?

Let’s start with the unpleasant truth: not all applications can be moved to the Internet. SD-And even if you have this feature, here are the key reasons:

🔹 Android Restrictions: Starting with Android 6.0 Marshmallow, Google introduced a rule that developers must explicitly allow their apps to be migrated to external drives, and many popular services (e.g. Facebook, Instagram, Banking) block this feature due to security risks.

🔹 Politics MIUI. Xiaomi firmware further limits portability, such as Redmi. 9A "Move to the button" SD" It may not be available even for supported applications if the memory card is formatted as portable storage (rather than as internal memory).

🔹 Technical limitations. SD-Cards (especially Class 4-10) are slower than internal memory, and transferring applications to them can lead to slowdowns, errors and crashes, PUBG Mobile or Genshin Impact does not support portability.

⚠️ Attention: If you are using SD-The card is an internal memory (Adoptable Storage function), then after it is removed, the smartphone may stop loading. 9A Due to low read/write speed of budget memory cards.

What do we do? Is there a way out? Yes, there are several. Next, we'll look at all the methods available, from simple to advanced.

Method 1: Transfer through standard MIUI settings

This is the easiest method, but it only works for a limited number of applications, and here's how to check if the port is available for your software:

1. Open Settings → Applications → Application Management.

2. Select the desired application (for example, Telegram or VK).

3. Click on "Storage".

4. If the "Move to" button SD-The card is active – press it and wait for the process to be completed.

📌 What to do if the button is inactive?

• 🔄 Reboot your smartphone – sometimes it helps the button to “appear.
• 📁 Check the format SD-Cards: It should be formatted as internal memory (but this is risky, see the warning above).
• 🔍 Update. MIUI: In new versions of firmware, the list of supported applications can be expanded.

💡 Tip: Move it to SD Only those applications that are not critical for speed (for example, messengers, music players.

Method 2: Use of the SD-The card is an internal memory (adoptable storage)

This method allows the system to be “deceived” by making it perceive SD-Advantage: You can port almost any application, disadvantages: high probability of lag, risk of data loss when you extract the card.

🔧 Step-by-step instruction:

1. Put it in. SD-smartphone-card.
2. Go to Settings. → Warehouse → SD-map.
3. Press "Three dots (⋮) → Storage settings → Internal memory".
4. Follow the instructions on the screen. Attention! The map will be formatted and all data on it will be deleted.
5. After formatting, restart the smartphone.
6. Now in the application settings should appear button "Move to SD".

⚠️ Note: This method is not recommended for Redmi 9A two-way: ✅ Class 10 memory cards (typical for the budget segment) are too slow to work as internal storage. ✅ When extracted SD-The application cards installed on it will stop working, and the system can issue errors.

📊 Comparison of read/write speed:

💡

If you still decide to use SD-Card as internal memory, buy a model with support UHS-I (U3) — For example, SanDisk Ultra A1 Samsung EVO Plus, they're a little faster than the standard Class 10, but they're still going to be way short of the internal memory.

Method 3: Transfer applications over ADB (for advanced users)

If standard methods don’t work, you can try forced porting over Android Debug Bridge (ADB), which requires connecting your smartphone to a PC and basic command line knowledge.

🛠 What's the matter:

• 🖥 Computer with Windows/macOS/Linux.
• 🔌 USB-cable (preferably original).
• 📦 Installed drivers ADB and Fastboot.
• 🔧 Included debugging by USB smartphone.

📝 Instructions:

1. Activate Developer Mode on Redmi 9A: Go to Settings → About Phone → MIUI version and click on it 7 times.

🔍 How to find out the application package?

Use the command:

adb shell pm list packages | find "appendix name"

For WhatsApp, the package is com.whatsapp.

⚠️ Note: Not all applications support forced transfer via ADB. If the team returns the mistake, Failure [INSTALL_FAILED_INVALID_INSTALL_LOCATION]", So transfer is impossible.

Method 4: Alternative Memory Release Methods

If the applications are transferred SD-The card is impossible or impractical, consider other ways to make room on the Redmi. 9A:

📂 Cleaning cache and unnecessary files:

🔄 Disabling pre-installed applications:

Xiaomi likes to install unnecessary software (e.g. Mi Video, Mi Music, GetApps) which can not be removed, but you can disable:

📲 Use of "Light" versions of applications:

Many popular services have lightweight versions:

• Facebook Lite instead of Facebook.
• Messenger Lite instead of the standard messenger.
• Twitter Lite (web version via PWA)

💾 Transferring data (not applications!) to SD-map:

Even if the apps are not portable, you can move their data (e.g. downloads, media files):

1. Open the file manager (Files or Mi Explorer).
2. Go to the app folder (e.g. WhatsApp → Media).
3. Select files and click "Move" by selecting SD-map.

💡

If none of the methods worked, consider buying a smartphone with a large amount of storage (like the Redmi 10A with 64GB) or using cloud storage to back up data.
