How to transfer applications to a memory card in Xiaomi Redmi Note 8T: a complete guide to debunking errors

Owners of Xiaomi Redmi Note 8T sooner or later, they face the problem of lack of internal memory - especially if the device is used for games, messengers or storage of multimedia. 64/128 GB of internal memory system MIUI It gets cached, updated, and app data quickly, and the solution seems obvious: transfer some of the software to a microSD card. But here, users are facing pitfalls: not all applications support portability, but the procedure itself in the Redmi Note. 8T It has nuances depending on the version MIUI type SD-map.

In this article, we will discuss all working ways to transfer applications to an external drive, including manual settings, use of the app. ADB You'll learn which applications can be ported without risking system stability, how to avoid errors like "Not enough space" or "The app doesn't support" SD-The difference between external storage and internal formatting of the memory card, and also the difference between external storage and internal formatting of the memory card. SD-maps and how to get around.

If you've tried to migrate apps through the standard Settings → Apps menu and you're rejected, don't despair. 80 percent of the time, the problem is solved by properly preparing your memory card or using alternative methods. The main thing is to take your time and follow the instructions Step-by-step.

1. Preparation of a memory card: which format to choose?

Before you port applications, you need to configure the microSD card itself correctly. Redmi Note 8T supports cards up to 512 GB (officially up to 256 GB, but tests confirm work with 512 GB models of class A2).

1. Portable storage - the card is used as a removable drive (photo, video, music).

2.Internal Storage – the card becomes part of the system (formatted as Adoptable Storage) Only in this case, the transfer of applications is possible, but with restrictions.

To choose the second option, follow the following steps:

1. Insert the card into the slot (microSD, microSDHC, microSDXC are supported).
2. Go to Settings → Memory → Memory Map.
3. Click on “Format as internal” (if the option is not available, see “Why is the formatting option not displayed?”).
4. Confirm the action and wait until it is completed (may take up to 10 minutes).

⚠️ Warning: Once formatted as an internal storage, the card cannot be retrieved without losing data, it will be encrypted and tied to the device. If you reset the phone to the factory settings, the card will have to be re-formatted.

If the option “Format as internal” is missing, check:

• 🔹 The card is not damaged (try formatting it on PC) FAT32 exFAT).
• 🔹 Card size is at least 16 GB (on cards less system blocks internal formatting).
• 🔹 There is no important data on the map (all files will be deleted).

2. Standard application portability through MIUI settings

Once the map is formatted as an internal storage, you can start migrating applications. In Redmi Note 8T with MIUI 12-14, the algorithm is as follows:

1. Open Settings → Applications → Application Management.

2. Select the application from the list (e.g. Telegram or VK).

3. Click on “Storage” → “Change” → “Memory Map”.

4. Confirm the transfer and wait for completion (may take a few minutes).

But here, users are disappointed: most apps don't have a portability option, like WhatsApp, Instagram or Google Play Store, blocking this feature at the code level, and even if the Change button is active, a notification may appear after clicking: “The application does not support the transfer to SD-Card due to security restrictions».

What do you do in this case? There are two options.

• 🔧 Use it. ADB (We will discuss in the next section).
• 📁 Only transfer cache and application data (not by yourself) APK-file).

3. Applications Transfer via ADB: Bypassing Restrictions

ADB (Android Debug Bridge is a debugging tool that lets you manually specify which apps to migrate to. SD-This works even for programs that block the transfer over the standard menu, and it's important that this method requires an unlocked bootloader and enabled debugging. USB.

5. Enter the port command (replace com.example.app with the application batch name, for example, com.whatsapp): adb shell pm set-install-location 2 This command sets the installation priority to the port. SD-map for all new applications.
6. To transfer an already installed application, use: adb shell pm move-package com.example.app

If the command is successful, you'll see a message of success, but there are nuances:

• 🔹 Not all applications support the work with SD-cards (for example, Sberbank Online or Tinkoff can block the launch of the).
• 🔹 After updating the application, it can automatically return to internal memory.
• 🔹 Some games, for example, PUBG Mobile or Genshin Impact will be lagging when you start from a class map A1.

⚠️ Attention: Use ADB It can cause applications to run unstable, especially if the memory card is slow (class) U1 Recommended minimum — UHS-I (U3) or A2.

4. Which applications can be ported and which ones can not?

Not all programs work equally well with external memory, and the compatibility table for popular applications on the Redmi Note 8T is below:

Particular care should be taken with:

• 💳 Banking applications (Sberbank, Tinkoff, VTB) – they often block work with the bank. SD-Cards due to security requirements.
• 🎮 Online-authorized games (Clash of Clans, Brawl Stars) – possible problems with account synchronization.
• 📷 Photo apps (Google Photos, Snapseed) – edited files may not be saved.

💡

Before transferring the banking application, back up its data through Settings → Annexes → Backup. This will help restore access if the application refuses to work with the SD-map.

5. Transfer errors and their solutions

When trying to migrate applications, users of the Redmi Note 8T often encounter errors.

Mistake 1: “Not enough space on the memory card”

Reason: The card is formatted as a portable storage or there is not enough free space for the application partition (the system reserves ~10% of the volume for its needs).
