Xiaomi Redmi 7A, with its modest 16 or 32 GB of internal memory, quickly fills with applications, especially if you are actively using messengers, social networks or games. Moving programs to a microSD card seems like a logical solution β but not everything is so simple. Unlike flagship models, the budget Redmi 7A has restrictions on working with external drives, and improper actions can lead to crashes or data loss.
In this article, we will discuss all the working ways to transfer applications to the USB flash drive β from standard MIUI functions to manual mounting through ADB. You will learn which memory cards are compatible with the device, how to avoid formatting errors, and why some programs fundamentally do not want to move to SD. And also β what to do if after transferring applications begin to slow down or issue errors.
β οΈ Important: Redmi 7A It works on Android. 9 Pie with a shell MIUI 10/11, where the Adoptable Storage function is officially disabled, which means that the application port is only partially possible β and we will explain in detail how to make the most of the available tools.
Which flash drive to choose for Redmi 7A: requirements and recommendations
Not every microSD card is suitable for porting applications. Xiaomi Redmi 7A supports drives up to 256 GB, but for stable work with programs, two parameters are critical: speed class and file system type.
Minimum requirements:
- πΉ Volume: from 32 GB (16 GB applications simply do not have enough space).
- πΉ Class speed: UHS-I (U1/U3) class 10. Class cards U3 preferably, they are less slow when working with applications.
- πΉ File system: exFAT or FAT32. For cards up to 64 GB is suitable FAT32, from above, exFAT only.
- πΉ Brand: SanDisk Ultra, Samsung EVO, Kingston Canvas - Proven Versions Without Counterfeiting.
β οΈ Attention: Cheap cards without a brand often have understated real write speeds, which leads to lags when you run ported apps. A1 Optimized for Android and shows stable performance.
| Characteristics | Recommended value | Consequences of non-conformity |
|---|---|---|
| Volume. | 32-256 GB | Applications will not have enough space or the map will not be formatted |
| Class speed | UHS-I U3 / Class 10 | Brake when starting programs, recording errors |
| File system | exFAT (for >64 GB) or FAT32 | The phone will not see the card or will not allow data transfer |
| Manufacturer | SanDisk, Samsung, Kingston | Risk of counterfeiting, low speed, rapid wear |
2. Preparation of the flash drive: formatting and verification
Before you transfer applications, you need to format the memory card, which will delete all the data, so you can copy important files to your computer in advance, and you can format it directly on your phone or via your PC, the second way is more reliable.
Method 1: Formatting in the phone
- Put the map in Redmi 7A.
- Go to Settings β Storage β Memory Map.
- Click Format β Internal Storage (if you need to port applications) or Portable Storage (if only for files).
- Confirm the action. It'll take 1-3 minutes.
Method 2: Formatting via PC (recommended)
- π₯οΈ Connect the flash drive to the computer through the card reader.
- π§ Open Disk Management (Win) + X β Disk management).
- π Find your card, right-click. β Format.
- βοΈ Select the file system: FAT32 β for cards up to 64 GB; exFAT for cards up to 128 GB or more.
- β Press OK and wait until it's finished.
π‘
If the phone doesnβt see the formatted card, try restarting the device or inserting a flash drive into another slot (if thereβs an adapter).
β οΈ Note: If you choose formatting as Internal Storage, the card will be encrypted and attached to the phone. Once retrieved, the data on it will not be available on other devices.
3. Standard Application Transfers through MIUI Settings
MIUI redmi 7A It allows you to transfer only part of the applications to SD-This is a system limitation: some programs (e.g., system or high security requirements) will remain in internal memory.
Step-by-step:
- Open Settings β Applications β Application Management.
- Select the application you want to transfer (such as Telegram or VK).
- Click Warehouse β Change β Memory Map.
- Confirm the transfer. It'll take 10 seconds to a few minutes.

β οΈ Warning: After porting some apps may run slower β this is normal for Redmi 7A Because of the limited read speed with microSD, it's especially noticeable in games and instant messengers with frequent notifications.

4. Transfer applications over ADB (for power users)
If the standard method didnβt work, you can use Android Debug Bridge (ADB), a debugging tool that lets you manually tell the system where to install applications, a method that requires a PC and basic command line knowledge.
What you need:
- π» Computer with Windows/Linux/macOS;
- π Cable USB (better-than-original);
- π₯ ADB Tools (download and unpack);
- βοΈ Included debugging by USB phone-on.
Instructions:
- Turn on USB debugging: Go to Settings β About Phone β MIUI Version (click 7 times until the message "You're a developer" appears). Return to Settings β Additional β Developer. Activate Debugging over USB.
Connect your phone to your PC and confirm your trust in your computer.
cmd
ADB
cd C:\platform-toolsadb devicesThe serial number of your Redmi 7A should appear.
com.example.app
adb shell pm move-package com.example.appπ‘
The pm move-package command doesn't work for all applications if a Failure error appears. [NOT_MOVED: Operation not allowed, means the transfer is blocked by the developer.
β οΈ Note: Some applications after transfer through ADB They may stop updating through Google Play, and then they'll have to be removed and reinstalled.
5. Alternative ways to free up memory
If porting apps hasnβt helped or isnβt possible, consider other memory optimization methods:
1. Clearing cache and unnecessary files
- π§Ή Go to Settings. β Warehouse β Cleanup.
- ποΈ Select Unnecessary Files and Cash Applications.
- π Press Clean (can be released up to 1-3 GB).
2. Transfer of media files to a flash drive
- πΈ Photo and video from the gallery:
- π΅ Music and downloads:
3. Disabling pre-installed applications
- π« Go to Settings. β Annexes.
- π Find unnecessary system programs (such as Mi Music or Mi Video).
- β Press Disable (Do not delete!).
π‘
Google Play Services and MIUI System applications cannot be disabled, as this will cause system failures.
6. Solving problems after transferring applications
Transferring applications to a flash drive can cause failures. Consider typical errors and their solutions:
| Problem. | Possible cause | Decision |
|---|---|---|
| Application won't start | The flash drive is disabled or damaged | Restart your phone, check the card on PC |
| Error "Application not installed" | Transfer over ADB with errors | Remove and install the application again |
| Brakes at opening | Low speed reading of the map | Use a U3 class card or transfer it back. |
| Disappeared data after the extraction of the flash drive | The map is formatted as an internal | Do not remove the map or copy the data in advance |
β οΈ Note: If the application stopped updating after the transfer, try it:
- Transfer it back to your internal memory.
- Update through Google Play.
- Remove it to the flash drive (sometimes helps).
