Owners of budget but productive smartphones often face a lack of built-in storage. Xiaomi Redmi 8, despite its popularity, often comes with 32 or 64 GB of storage, which is quickly filled with modern apps and media files. When the internal space runs out, the device starts to run slower, and you can't take a new picture.
The best solution is to use a microSD memory card, which frees up precious megabytes to run the system and install updates, and in this article, we will detail how to properly configure and move your images to an external medium, avoiding common errors.
The process of data transfer does not require special technical skills, but requires attention to detail. Incorrectly extracting a map or a failure in writing can lead to data loss. So it is important to follow the algorithm of actions that we will describe below, so that your memories remain safe.
Preparation of a memory card and installation in a slot
Before you think about transferring files, you need to physically install the drive into the device. The slot in Redmi 8 is combined, so in the second compartment you can install either a second one. SIM-You'll need a special paper clip that comes with the package, or a thin needle.
Carefully remove the tray, taking care not to damage the contacts. Make sure the memory card is inserted with the correct side that matches the icon on the tray. Once installed, the system must automatically identify the new drive.
💡
Use a Class 10 or UHS-I memory card to save photos quickly and without delay, especially when shooting high-resolution video.
If you don't notice a new card, check it on another device or computer. Sometimes budget memory cards may not be properly defined by Android, which requires formatting.
- 📱 Make sure the phone is completely off before installing the card (although Hot-swap support is available, it’s safer to do so on a device that’s turned off).
- 💾 Check the integrity of contacts on the memory card – they should be clean and without oxidation.
- 🔒 Pay attention to the position of the fixator in the tray - the card should sit tight and not stagger.
When you turn on your smartphone, you usually see a message in the notification curtain that you've discovered a new drive, and the system may suggest that you use it as a portable storage device or as part of your internal memory, and for our task of storing a photo, you should choose the first option.
Setting up photo saving in the Camera application
The most efficient way to free up space is to set up automatic saving of new images directly to the external media. In the standard MIUI Camera app, which is installed on the Xiaomi Redmi 8, this feature is implemented quite conveniently. You do not need to manually transfer files every time.
To activate this option, open the camera app and click on the three horizontal bars in the upper right corner of the screen. In the menu that opens, select Settings. Scroll down the list of options to the storage section.
☑️ Camera setup
Here you'll see the Save option. When you click on it, select your memory card. Now all new photos and videos will be recorded by default. SD-This is a critical setting for owners of devices with a small amount of internal memory.
⚠️ Note: If you remove the memory card when the function is activated, the new photos will no longer be saved until you return the drive or change the settings back to internal memory.
It is worth noting that shooting modes with a very high bitrate or serial shooting in the RAW-Format (if supported by third-party applications) may sometimes ignore this rule and write data to internal storage to ensure maximum buffering speed.
Transferring existing photos through the Explorer
Setup the camera solves the problem of future images, but what to do with the thousands of photos that are already available? To move them, you need to use a system file manager. In the MIUI shell, it is called Explorer and has a yellow icon with a folder.
Open the app and go to the section where file categories are displayed. Find the Images category or go to Internal Sharing → DCIM → Camera. This is where all your pictures are stored. Select the files you want with a long press or select the "Select All" option.
Once highlighted, click the Move button (scissors icon) or Copy button (two sheets icon) and don't confuse these actions: moving will remove the originals from internal memory, and copying will create duplicates, which will take up even more space.
Then go to the root of the memory card (usually indicated as SD-card mi_sdcard1). Create a new folder, for example, «Archive_Photo», So you don't mix files with system data, you can put the copied files in this directory.
| Action. | Implementation time | Risk of data loss | Occupied seat |
|---|---|---|---|
| Copying | Average. | Low. | Doubles (temporarily) |
| Relocation | Fast. | Medium (failure) | It doesn't change. |
| Removal | Instantly. | High-pitched | Released. |
| Formatting | Long time. | critical | Complete cleaning |
The process of moving a large amount of data can take a few minutes.Do not lock the screen and do not start heavy games during this operation, so as not to overload the memory controller of the Xiaomi smartphone.
Use of the “Cleanup” function in the Security application
MIUI has a built-in device optimization tool that can analyze storage, which can automatically suggest moving large files or removing duplicates, and it's a convenient way for those who don't want to manually sort through folder paths.
Run the Safety app (green zipper icon). Select Clean up. The system scans the device and shows how much space the photos take up. Often there is a "Clean up" button or a recommendation to move the data to the device. SD-map.
If the system suggests removing "cache" or "unused packets," read carefully what exactly you're removing.Automatic cleaning can sometimes remove thumbnails of photos, making the gallery take longer to download previews the next time it opens.
Why can't the system see all the photos?
This is good for quick prevention, but for total archive transfers over a period of several years, it is still more reliable to use the manual method through the Explorer described in the previous section, so you will control exactly which files are where they are.
Solving problems with the definition of a memory card
Sometimes users are faced with a situation where the phone stops seeing the memory card or writes an error «SD-This could be due to the file system. Android works best with the format. FAT32 exFAT.
If your card was formatted on your computer in NTFS, your phone won't see it. You'll need to connect the card through the card reader to your PC and format it into a compatible format, and remember that formatting will destroy all the data on the media.
⚠️ Before formatting, be sure to copy important data from the card to the computer, otherwise it will be extremely difficult or impossible to restore them.
The problem may also lie in the oxidation of the contacts of the slot in Redmi 8. Try to gently wipe the contacts of the card with an alcohol napkin and blow the smartphone slot with compressed air. Frequent extraction of the tray contributes to the entry of dust into the case.
In rare cases, re-activating the card through the settings menu helps. Go to Settings → Storage, click on the memory card and select Format. If that doesn't help, it may be that the drive has physically failed, which often happens with cheap models after an active write cycle.
Optimization of the gallery after the transfer
Once you've moved a photo to a memory card, the gallery may be unstable for a while, and it needs to index new files and update its media database, which is normal behavior on Android.
If you notice that photos are missing or appearing in black squares, try clearing the cache of the Gallery app. Go to Settings → Apps → All Apps → Gallery → Memory → Clear the cache. Your photos will not be deleted.
💡
Regularly checking the integrity of files on the memory card via a computer will help prevent the sudden loss of the archive of photos.
For ease of viewing, it is recommended to create a clear folder structure on the memory card by year or event. Chaotic storage of thousands of files on an external medium can lead to the fact that a standard viewer will open albums for a long time.
- 📂 Create themed albums manually for important events.
- 🔄 Regularly back up important photos to your cloud service or PC.
- 🛡️ Set a password for a hidden album if you keep confidential photos.
By following these simple guidelines, you’ll turn your Xiaomi Redmi 8 into a reliable storage for media files without worrying about space shortages.Proper memory management prolongs the life of your device and keeps your data intact.
