How to install applications SD-map 7A: work-in

Owners of Xiaomi Redmi 7A Often face the problem of lack of internal memory, especially if the device has many applications or games. SD-A card can be a great solution, but not everyone knows how to do it correctly. In this article, we will discuss all the current methods of installing applications on an external drive, including the standard Android 9 Pie features and hidden features. MIUI. It is important to keep in mind that not all applications support portability – this depends on the developer’s policy.

Before you start the transfer, make sure that your SD-card meets the requirements:

• 🔹 Class 10 speeds are not lower than Class 10 (recommended) UHS-I play-off)
• 🔹 Volume from 16 GB (optimally 64-128 GB for comfortable work)
• 🔹 Formatting in FAT32 or exFAT (for cards) >32GB)
• 🔹 No physical damage (check on another device)

1. Standard portability through Android settings

The easiest way is to use Android 9 Pie’s built-in feature, but it doesn’t work with all apps, only those that support external drive installation, and developers can block this capability to protect data or optimize performance.

To check the availability of transfer:

1. Open the Settings → Applications.
2. Select the desired application from the list.
3. Click on "Storage".
4. If the option is available, the button "Change" or "Move to" will appear. SD-map".

Limitations of the method:

• 🚫 Does not work with system applications (MIUI, Google Play Services).
• 🚫 Some of the data may remain in internal memory (cache, settings, etc).
• 🚫 After the transfer, some widgets stop working.

⚠️ Note: If the "Move" button is inactive, it means that the developer has blocked the function. Attempts to bypass the restriction through root can lead to malfunctions in the application.

2. Formatting SD-maps as internal memory

A more radical method is to make SD-It's part of the internal storage, and it allows you to install applications directly on it, but it has serious implications:

• 🔄 The card will be encrypted and will not be read on other devices.
• 🔄 After the map is removed, the applications will stop working.
• 🔄 The speed of work depends on the class. SD-Cards (cheap models slow down the system).

Formatting instructions:

1. Put it in. SD-map 7A.
2. Go to Settings. → Warehouse.
3. Click on the title. SD-map → "Set up" → "Internal memory".
4. Confirm the formatting (all data will be deleted!).
5. Once completed, restart the phone.

Important: This method irreversibly links the card to the device, and if you extract it for use in another phone or camera, the data will be unavailable without formatting.

Backup your card data | Check speed class (at least Class 10) | Charge your phone to 50% or more | Disable important notifications during the process

3. Transfer applications over ADB (for power users)

If standard methods don't work, you can use Android Debug Bridge (ADB), a computer debugging tool that allows you to force-transfer supported applications, but requires command-line skills.

Step-by-step:

1. Turn on Developer Mode on Redmi 7A: Go to Settings → About Phone. Click 7 times on MIUI Version (you will be a developer notification).

"Debugging by USB"

Settings → Additional → For Developers

ADB-driver

adb devices

Make sure the device is identified.

package.name

adb shell pm set-install-location 2

This gives priority to the installation of SD-map for supported applications.

To find out the name of the application package, use the command:

adb shell pm list packages | grep "keyword"

For example, for Facebook, type "facebook" into grep.

⚠️ Attention: Misuse of the right ADB This can cause system failures. Do not change the settings of applications critical to MIUI (For example, com.miui.home).

4. Use of third-party utilities

If previous methods didn't work, you can use specialized programs, such as AppMgr III (formerly App 2 SD) or Link2SD (requires root).

• 📱 Port applications even if the standard method is not available.
• 📱 Create symbolic links to save space.
• 📱 Clear cache and unnecessary files.

Instructions for AppMgr III:

1. Download the app from Google Play.
2. Start and grant access rights to the storage.
3. In the list of applications, click on the desired and select "Move to the SD-map".
4. If the option is inactive, try Clear Cache or Clear Data.

Link2SD requires root rights, but offers more features:

• 🔧 Transfer APK, DEX and LIB file.
• 🔧 Automatically linking new applications to SD-card.
• 🔧 Integration with the system for notification of new installations.

💡

Before use Link2SD Create a second section on SD-This is a map using MiniTool Partition Wizard, which allows you to store application data separately from media files.

5. Solving common mistakes

When transferring applications to SD-mapping 7A We're going to have a lot of mistakes, and we're going to look at the most common ones and how we can fix them.

Mistake: "SD-The card does not support this operation"

• 🛠️ Reason: The map is formatted in NTFS damaged.
• 🛠️ Solution: Reformatting into FAT32 or exFAT via PC.

Error: "I failed to move the application"

• 🛠️ Reason 1: The app does not support portability (e.g. WhatsApp, Banking apps).
• 🛠️ Reason 2: There is not enough space on the map.
• 🛠️ Solution: Make room or use ADB forced transfer.

Error: Apps are stained after transfer

• 🛠️ Reason: Slowly SD-Card (class below Class 10).
• 🛠️ Solution: Return the app to internal memory or buy a faster card.

If the app stopped updating through Google Play after the transfer, try:

1. Put it back in your inner memory.
2. Update through the store.
3. Move it back to SD-map.

6.Memory optimization without application portability

If the transfer is SD-The card is not possible or desirable, and internal memory can be optimized in other ways:

• 🧹 Cache cleaning: Settings → Warehouse → Clear the cache.
• 🧹 Delete unnecessary files through MIUI Cleaner.
• 🧹 Disabling Auto-Update Apps in Google Play.
• 🧹 Using Google Drive, Mi Cloud for Photos and Videos.

For games with large data files (e.g. PUBG Mobile, Call of Duty), you can use the Clear Data feature after the update, which will delete unnecessary temporary files, but save progress (if it is synced with the account).

Hidden MIUI function:

Redmi 7A has a built-in memory analysis tool:

1. Go to Settings. → Warehouse.
2. Click on "Free space."
3. The system will prompt you to delete unnecessary files, duplicates and large media.

💡

Regular cache cleaning and uninstalling unused applications can free up to 2–5 GB of memory without transferring to the computer. SD-map.

7. Comparison of methods: which one to choose?

The choice of transfer method depends on your goals and technical skills. Below is a comparison table:

For most Redmi 7A users, the best solution is to combine:

1. Standard portability of supported applications.
2. Formatting SD-Cards as internal memory (if the card is fast).
3. Regular cleaning of the cache through MIUI Cleaner.

If you’re willing to take a chance, ADB or Link2SD will open up more options, but require caution.
