Xiaomi Redmi 7A is still a popular budget smartphone due to its reliability and optimized firmware Android Go Edition. However, 16 or 32 GB of internal memory quickly run out, especially if you actively install applications. The solution is the use of a microSD card, but with nuances: not all applications can be ported, and the process itself depends on the version of MIUI and the system settings.
In this article, we will analyze all the ways of installing applications on SD-map 7A: From standard Android features to workarounds using ADB. We also explain why some programs cannot be migrated to an external drive due to the limitations of Android Go, and how to make the most of the available space. MIUI 14 (at the time of 2026).
Why Redmi 7A doesnโt see the memory card or let it install apps
The problem of transferring applications to SD-map 7A It is related to two key factors:
- ๐ฑ Android Go Edition โ a lightweight version of the OS, where the Adoptable Storage function (conversion) SD-- I.D. cards are disabled by default, so you can work on a weaker hardware.
- ๐ง Limitations MIUI โ Even if the card is formatted as internal memory, some system applications (such as Google Play Services) cannot be ported.
- ๐พ Type of file system - cards FAT32 โข do not support files larger than 4GB, and exFAT may not be readable on some devices.
In addition, application manufacturers themselves can block the ability to transfer to SD. For example, messengers (WhatsApp, Telegram) or games with cheating protection (PUBG Mobile, Free Fire) are often tied to internal memory.
Preparation of a memory card: formatting and selection of a file system
Before you try to migrate applications, you need to properly prepare the microSD card, which depends on whether the system can use it as an extension of internal memory or only for storing files.
Redmi 7A has two formatting options:
- Portable storage (FAT32/exFAT) - the card is used as a removable drive, applications cannot be moved to it, but you can store photos, videos and documents.
- Internal Storage (ext4) โ The card becomes part of the system, allowing applications to be installed on it, but once retrieved, the data will not be available on other devices.
To format the card as an internal memory:
- Insert the card into the Redmi 7A slot.
- Go to Settings โ Storage โ Memory Map.
- Click Format as internal (if the option is active).
- Confirm the action and wait until the process is completed (it can take up to 10 minutes).
Make a backup of the card | Make sure the card is not fake (use H2testw utility) | Check the speed class (UHS-I Class 10 recommended) | Charge the phone at least 50%-->
โ ๏ธ Note: Once formatted as internal memory, the card cannot be read on a PC or other phone without special utilities.
Method 1: Transfer applications through MIUI settings (without root)
If the card is formatted as internal memory, you can try migrating apps in the standard way, but in Android Go, this feature is often hidden or limited. Here's how to find it:
- Open Settings โ Applications โ Application Management.
- Choose the app you want (like Facebook or Instagram).
- Click Warehouse โ Change (if the button is active).
- Select a Memory Card and confirm the transfer.
If the button is not Change, it means:
- ๐ซ Application does not support portability (depending on the developer).
- ๐ The card is not formatted as internal memory.
- ๐ต In your version. MIUI The function is disabled (relevant to Android Go).
Why can't some apps be moved?
Method 2: Installation of applications on SD-default-card
In some versions of MIUI, you can set up new applications directly to the memory card.
- Go to Settings โ Storage โ Preferred installation location.
- Select a Memory Card (if the option is available).
- Confirm the change.
However, this method does not always work:
- โ Maintained in MIUI 10-12 for standard Android.
- โ In Android Go (like in Redmi) 7A) option is often missing.
- โ ๏ธ Even if the installation is carried out SD, cache and data can remain in internal memory.
๐ก
If the "Preferred Installation Location" option is missing, try updating your firmware to the latest version of MIUI via Settings โ About Phone โ System Update. Sometimes the feature appears after the update.
Method 3: Using ADB for forced transfer (for experienced)
If the standard methods donโt work, you can use Android Debug Bridge (ADB) โ A debugging tool through a PC that will manually tell the system which applications to port to. SD-map.
This will require:
- ๐ฅ๏ธ A computer with installed Xiaomi drivers and ADB Tools.
- ๐ฑ Included debugging by USB on the Redmi 7A (Settings โ The phone. โ Version. MIUI โ 7 times tap to unlock Developer Settings).
- ๐ Cable USB (preferably original).
Instructions:
- Connect the phone to the PC and allow debugging.
- Open the command prompt (Windows) or terminal (macOS/Linux) in the folder with ADB.
- Enter the command to check the connection: adb devices must appear serial number of the device.
- Find out the batch name of the app (for example, for Facebook it is com.facebook.katana).
- Run the port command: adb shell pm set-install-location 2 This will install all new applications on the SD-default-card.
โ ๏ธ Note: Not all apps will work properly after a forced transfer, for example, WhatsApp may stop sending notifications, and games may crash when downloaded.
| ADB Team Team | Description | Example of use |
|---|---|---|
| adb shell pm get-install-location | Shows the current installation location (0 โ auto, 1 โ internal, 2 โ SD) | 2 - installation on the memory card |
| adb shell pm set-install-location 2 | Set up SD-map | To migrate new applications |
| adb shell pm move-package com.example.app | Transfers a specific application to SD | com.facebook.katana - for Facebook |
| adb shell pm set-install-location 0 | Returns automatic seat selection | If the transfer has caused errors |
What to do if apps donโt carry or crash after the transfer
Even after successful transfer, some programs may not work as well.
- ๐ The app will fly out when it opens. โ Try to clear the cache (Settings) โ Annexes โ Clear the cache or transfer it back to internal memory.
- ๐ต No notifications coming. โ Messengers (like Viber) often require internal memory for background work.
- ๐ฎ Games are slowing down โ Class 10 memory cards are slower than the built-in eMMC. For games, it is better to use internal storage.
- ๐ You can't update the app. โ Transfer it back to internal memory, update it, then move it back to the internal memory. SD.
If problems persist, check:
- ๐ ๏ธ Memory Card Status โ Use the Utility SD Insight (Android) or H2testw (PC for diagnostics.
- ๐ Formatting โ if the card has been used for a long time, reformat it into ext4 via phone settings.
- ๐ฑ Updates MIUI โ In new versions of firmware can fix bugs with work SD-map.
๐ก
Class A1 or A2 memory cards (like SanDisk Ultra A1) are better optimized for app installation than regular Class 10. They work faster with small files, which is critical for Android.
Alternative solutions: how to free up space without transferring to SD
If transferring applications to a memory card is impossible or ineffective, use alternative ways to free up space:
- ๐งน Cleaning the cache - in Settings โ Warehouse โ You can delete up to 1-3 GB of unnecessary data.
- โ๏ธ Cloud Storage โ Move photos and videos to Google Photos or Mi Cloud (Redmi) 7A 5GB is free).
- ๐๏ธ Removing System Garbage โ Use the Inbuilt Utility Optimization in MIUI or the Files by Google application.
- ๐ Lite versions of applications โ replace heavy social networks with lightweight ones (Facebook Lite, Messenger Lite).
- ๐ต Offline content โ in YouTube Music or Spotify, set up a cache on SD-map (Settings) โ Warehouse).
You should also turn off automatic updates to apps in Google Play:
- Open Play Store โ Profile โ Settings โ Network settings.
- Select Auto Update Applications โ Only via Wi-Fi or Do not update automatically.
