The internal memory of modern Xiaomi smartphones fills up rapidly, especially if you are actively using the camera for shooting in high resolution. RAW or 4K video can take up gigabytes of space in minutes, causing annoying notifications of space shortages. The solution is to use an external microSD card that allows you to expand storage and free up valuable megabytes for the system to work.
Unfortunately, in the latest versions of the MIUI and HyperOS shell, manufacturers often hide settings or change the logic of working with external drives. Users are faced with the fact that even after installing the card, images still fly into internal memory. In this guide, we will discuss all the current ways of forced transfer of media files, including hidden camera settings and system restrictions.
It is important to understand that the setup process may vary depending on your device model and firmware version.We will look at the universal methods that work on most current Redmi and Poco smartphones. Follow the instructions carefully to avoid data loss and adjust the media correctly.
Preparation of a memory card and installation in a slot
Before you set up a save, you need to make sure that the memory card is properly installed and formatted. Poor or damaged drives can cause camera malfunctions and loss of images. It is recommended to use cards of class speed 10 or higher, especially if you plan to shoot high-resolution video.
Put the card in the smartphone tray, observing the orientation of contacts, and wait for the notification system. If the device offers to select the mode of operation, select "Use as portable storage" (Portable storage), which allows you to store photos, videos and music that can be read on other devices, unlike the "Internal memory" mode, which encrypts data for a particular phone.
- 📸 Make sure the card is inserted before clicking and is defined by the system in the About Phone menu».
- ⚡ For the filming 4K Video requires a recording speed of at least 30 MB/s (standard) U3).
- 🛡️ Before formatting, save important data from the card to the computer, as the process will delete all the content.
⚠️ Note: If you use Adoptable Storage, removing the card without first unmounting can lead to irreversible data loss and application failure.
Once installed successfully, the system can offer to transfer existing files, which is a useful feature, but it can take a long time depending on the amount of data, it is better to set up new shootings first, and transfer old files manually through the file manager, so as not to overload the processor while the camera is running.
Setup the camera to record to an external drive
The most common question users have about why the camera ignores the installed map. Xiaomi’s standard Camera app often lacks an explicit storage switch button in the main interface.
Open the camera app and tap the three horizontal bars in the upper right corner to enter the menu. Select Settings (cogs). Scroll down to Additional Settings or Advanced Settings. That's where the Save to Save to Settings switch is located. SD-Activate it, and all new images will be automatically sent to an external medium.
- 🔍 Look for the switch at the bottom of the camera’s settings list, sometimes hidden under the “More” option».
- 📹 Check the video settings separately, as in some versions MIUI They are regulated regardless of the photo.
- 🔄 After enabling the function, take a test shot and check its location through the gallery.
☑️ Checking camera settings
If you haven’t found one, your smartphone model or firmware version may not support automatic SD recording through a standard app, and you can use third-party apps from Google Play that have more flexible save path settings, such as Open Camera or ProCam X.
Why did the SD save setting disappear?
Transfer of already taken photos manually
Even if you have automatic saving set up, you probably still have a gallery of old photos that take up space, and you can transfer them to the system without installing additional software, and this requires a built-in File Manager.
Go to Explorer and select Images category or go to internal memory. DCIM, Then you go to Camera. You can select the photos you want with a long press, then you can click on the "More" button (three dots) and you can select "Move" or "Copy." As your target directory, you can select yours. SD-Create a map and create a folder, for example, Old_Photos.
| Type of data | Standard path (Internal) | Pathway SD-map | Recommendation |
|---|---|---|---|
| Photo from the camera | /storage/emulated/0/DCIM/Camera | /storage/sdcard1/DCIM/Camera | Move folders by month |
| Screenshots | /storage/emulated/0/Pictures/Screenshots | /storage/sdcard1/Pictures/Screenshots | You can remove without |
| Photo from messengers | /storage/emulated/0/Android/media/com.whatsapp | /storage/sdcard1/Android/media | Requires access rights |
| Video | /storage/emulated/0/DCIM/Camera | /storage/sdcard1/DCIM/Camera | Move first |
Use Move instead of Copy if you want to make room right now, but if there are too many files, you better copy them first, make sure they're intact, and then delete the originals, which will take longer, but will protect you from accidentally losing important memories if the process fails.
💡
Use the Cleanup feature in Xiaomi’s Security app to find duplicate photos before transferring so you don’t copy the trash to a new map.
Use of cloud services and synchronization
An alternative to a physical memory card is cloud storage, although it requires an Internet connection. Google Photos or Xiaomi Cloud allows you to free up space on your device by storing originals on the network. This is especially true if the memory card slot is not in your model.
Google Photos has a “Free Space” feature that removes images from your device that are already securely stored in the cloud. Xiaomi users can use synchronization with Mi Cloud, where photos are sorted by album and can be accessed from any device under your account.
- ☁️ Google Photos provides 15GB of free space, with Gmail.
- 📱 Xiaomi Cloud often offers free 5GB, but the rates can be expanded.
- 📉 The cloud won’t save you if you don’t have access to mobile internet or Wi-Fi.
The main disadvantage of cloud solutions is the dependence on connection speed and tariff plan. 4K It can quickly run out of mobile traffic «SD-file-card + Cloud for Important Photos is the most balanced approach to data storage.
Solving problems with writing and reading
Sometimes users are faced with a situation where the camera gives an error recording or photos simply do not save. Most often the problem lies in the file system of the card. Android prefers the format exFAT or FAT32 for external drives. If the card is formatted in NTFS, the phone can see it, but will not be able to record data.
You can check and correct errors through your phone settings. Go to Settings → The phone. → Storage, click on your name. SD-You can select "Storage settings" and you can select "Format" before you do it, make sure that the data is copied, because formatting will destroy all the information.
⚠️ Warning: If the phone constantly requires you to format the card or does not see it after rebooting, it is possible that the contacts of the card have oxidized.
It’s also worth checking the permissions for the Camera app. In modern versions of Android, file access is strictly regulated. Go to Settings → Apps → All Apps → Camera → Access Rights and make sure that access to Photos and Videos or Files is allowed. Without this, the system application simply cannot create a file on an external medium.
💡
Formatting a memory card directly in the phone settings (rather than on a computer) ensures the correct file system and optimal smartphone performance.
Android Limitations and MIUI Features
Starting with Android 11 and up, Google implemented Scoped Storage, which restricts applications from accessing arbitrary files on external memory, which means that even with a memory card, some applications can stubbornly store data in internal memory, ignoring system settings.
Shell MIUI And the new HyperOS also has its own optimization features. Aggressive energy saving can put the reading process to sleep. SD-card, which leads to delays in taking serial photos or brakes when recording videos. In such cases, it is recommended to turn off energy savings for the Camera and Gallery application.
And remember, physical wear and tear. Memory cards have a limited resource of overwrite cycles. If you notice that photos are being saved longer than usual or that there are broken files, you may be running out of time, and then no setup will help, and you'll need to replace the drive with a new one, preferably from proven brands like SanDisk or Samsung.
