Owners of modern smartphone series Galaxy often face an acute shortage of built-in storage, especially if the device comes with a minimum amount of memory. The only effective solution to expand storage capabilities without data loss is to use remote memory card microSD. However, by simply inserting the drive into the slot, you will not automatically redirect all new files to the desired location.
The system Androidinstalled on the devices Samsunghas its own characteristics of data flow distribution. By default, many applications, including browsers and instant messengers, continue to write information to the internal memory, ignoring the installed drive. This leads to the system partition quickly filling up and the interface to slow down.
In this guide, we will look in detail at how to force changes to save paths for various types of content. You will learn how to configure camera, browser Chrome and system bootloader so that all new data automatically ends up on the memory card, freeing up valuable internal space.
Preparing the memory card and initial setup
Before Before changing software settings, you must physically install the media and make sure it works correctly. Insert the microSD card into the tray of your smartphone using a paper clip or a special key. After the system detects the drive, open the application My filesto check the availability of external storage.
The operating system may prompt you to format the card the first time you use it. This is a standard procedure necessary to create a correct file structure compatible with Android. Please note that formatting will delete all data already written to the card, so save important files on your computer first.
For optimal performance, it is recommended to choose cards with a speed class of at least UHS-I U3 or V30. Slow drives can cause delays when saving high-resolution photos or recording 4K videos. After formatting, the system will give the card a name that will be displayed in the file manager.
⚠️ Attention: Do not remove the memory card while recording files or running applications that use its resources. This can lead to file system corruption and data loss beyond recovery.
Use memory cards up to 1 TB for maximum compatibility with mid-range and flagship Samsung smartphones.
Changing the save path for the system bootloader
The main stream of files downloaded from the Internet is controlled by the system application Downloader (Download). This is where documents, APK installation files, and media files are downloaded by default from browsers that use the system download component. Changing this setting is a priority.
To redirect the stream, open the app Bootloader on your device. In the upper right corner of the screen, find the menu icon, represented by three vertical dots. Click on it and select the item Settings in the drop-down list.
In the menu that opens you will see the option Save location. By default, the value "Device memory" is selected there. Click on this item and the system will offer an alternative - Memory card. After selecting an external drive, all subsequent downloads will be automatically saved to the root folder Download on microSD.
☑️ Checking bootloader settings
It is worth noting that this setting affects mainly files downloaded through the standard Android interface. Some third-party browsers may have their own internal settings that override the system selection, so they must be configured separately.
Setting up saving photos and videos in the Samsung camera
The camera is one of the most voracious applications in terms of disk space consumption. Pictures in format RAW or video in resolution 8K take up gigabytes of space in a matter of minutes. Transferring media files to external media allows you to shoot with virtually no restrictions.
Launch the application Camera and go to photo mode. In the upper left corner of the screen, place the gear icon, which is responsible for device settings. Click on it to enter the configuration menu.
Scroll down the list of options to the "Save Location" section. Activate the switch opposite the item Memory card. Now all new pictures and videos will be saved to a folder on an external drive, bypassing the internal memory. Memory card memory DCIM/Camera on an external drive, bypassing the internal memory.
| File type | Folder in internal memory | Folder on memory card | Approximate size |
|---|---|---|---|
| Photo (JPEG) | DCIM/Camera | DCIM/Camera | 3-5 MB |
| Video (Full HD) | DCIM/Camera | DCIM/Camera | 100-200 MB/min |
| Photo (RAW) | DCIM/Camera | DCIM/Camera | 25-40 MB |
| Slow-motion video | DCIM/Camera | DCIM/Camera | 300-500 MB/min |
What happens to old photos?
Changing camera settings does not automatically move old pictures. You need to manually transfer files from the internal memory to the card through the My Files application by selecting the DCIM folder and using the Move function.
Configuration of Chrome and Samsung Internet browsers
Web browsers often ignore the system bootloader settings, using their own data saving algorithms. To ensure complete control over the storage, you need to check the settings of each installed browser separately.
In the browser Samsung Internet the setup process is intuitive. Open the menu (three bars at the bottom right), go to Settings and find the section Web pages and downloads. Inside this menu, select "Save Location" and specify Memory card.
The situation with the browser Google Chrome is more complicated. In the latest versions of the application, the ability to select a save path has been eliminated in favor of a single system storage. If your boot loader is configured correctly (as described in the previous section), then Chrome will follow this rule.
However, if files continue to be saved to internal memory, check for browser updates. In some cases, clearing the application cache through the menu helps. Settings → Applications → Chrome → Storage → Clear cache.
⚠️ Attention: The browser interface may change after major updates. If you do not find the indicated items, use the search inside the settings menu for the word “saving” or “downloads”.
Transferring installed applications to an external drive
The desire to transfer the applications themselves (APK files) to a memory card is common, but in modern versions Android this function is severely limited developers. The system allows you to move only those apps whose authors have explicitly allowed this in the application manifest.
To check the possibility of transferring, go to Settings your smartphone, select the section Applications and open the card of the app of interest. Click on item Storage. If the button Change is active, you can select a memory card as the installation location.
If the button is inactive or missing, transfer is not possible using standard means. Attempts to use third-party utilities or developer mode (force_external) often lead to unstable applications, since the speed of reading data from microSD is lower than that of the built-in flash drive.
The best strategy is to transfer only heavy media files and documents, leaving fast-running applications in the internal memory. This will ensure a balance between free space and high interface performance.
Managing files and eliminating possible errors
After setting all the parameters, it is recommended to audit the files. Open the dispatcher My files and make sure that new downloads actually appear in sections related to the memory card (usually designated as SD card).
Sometimes users are faced with a situation where the phone stops seeing the card after a reboot. This may be due to oxidation of the contacts or incorrect removal in the past. Try removing the drive, wipe the contacts with a soft cloth and insert it back until it clicks.
It is also worth remembering the difference in write speeds. If you notice that saving files is slower than usual, your memory card may be more than 90% full or have a low speed class. In this case, it is recommended to transfer the archived data to a PC and format the card again.
System memory is always faster than a memory card. Store only media files and documents on microSD, but do not install heavy games and system utilities there.
Frequently asked questions (FAQ)
Is it possible to make a memory card the main memory of the phone?
In modern smartphones Samsung's "Adoptable Storage" feature, which allows you to combine the internal memory and the card into a single space, is officially disabled by the manufacturer. The card only works as a portable storage device for media files and documents.
Why does the gallery show empty albums after transferring photos?
The Android media scanner takes time to index new files on external storage. Wait a few minutes or. reboot the device for photo thumbnails to display correctly.
