Owners of budget smartphones often face a lack of built-in storage, and the model Samsung Galaxy A10 is no exception. Only 32 gigabytes of internal memory quickly fills up with system files, application updates and personal content, which slows down the device.
Fortunately, the Android architecture allows you to expand the capabilities of the gadget using an external drive microSD. Proper organization of files and transferring your media library to a memory card is the only effective way to free up precious space for the system without buying a new phone.
In this article we will look in detail at what files can be moved, how to set up automatic saving by the camera and what restrictions exist when working with applications.
Preparing a memory card and smartphone
Before you start transferring data, you must install and format the drive correctly. Insert microSD the card into the slot at the end of the case using the special clip included in the kit, and wait for the system to notify you that a new device is connected.
If the card was previously used in another device, Android may prompt you to format it. Formatting will completely delete all existing data, so be sure to copy important information to your computer in advance if it there.
⚠️ Attention: During the formatting process, make sure that the smartphone battery charge is at least 40%. A sudden power outage can damage the file system of the card or the drive itself.
After installation, the system will prompt you to select a usage mode: as portable storage or as part of the internal memory. For the A10 model, it is recommended to select portable storage in order to be able to quickly remove the card and read it on another device without losing data.
- 📱 Insert the card into the phone off or through the notification menu after turning it on.
- 💾 Select the "Use as portable storage" option the first time startup.
- 🔄 Wait until the system completes error checking and formatting.
- 📂 Make sure that a new “SD card” section has appeared in the file manager.
After successful preparation, the drive is ready for recording. Now you can start moving files that take up the most space in the internal memory.
Transferring photos and videos through the Gallery
The largest block of data in any smartphone is media content. Photos and videos taken with the camera are saved to internal memory by default, but they can be moved in bulk.
Open the app Gallery and go to the Camera album. Select the photos you want, or use the Select All feature if you plan to clear your memory completely. Click on the menu (three dots) and select the “Move” option.
In the navigation window that opens, specify the path to the memory card: SD card → Pictures → Camera. If there is no Camera folder on the external drive, the system will prompt you to create it, or you can select any other directory.
Before bulk transfer, create a folder on the memory card with a clear name, for example "Archive_2026", so as not to get confused with files later.
The copying process may take time depending on the number of files. Do not minimize the application during the operation to avoid recording errors.
- 📸 Open the Gallery and select all photos for a long period.
- 📂 Click "Move" and select the root folder of the SD card.
- ⏳ Wait until the process is completed, the indicator will show the progress.
- ✅ Check the availability of files on the card through the file manager.
Setting up automatic saving to the Camera
In order not to waste time on manual transfer in the future, you can change the camera settings. This will allow new pictures to immediately go to the external drive, leaving the internal memory free.
Go to the application Camera and click on the gear icon in the upper corner of the screen. Find the item “Storage location” and switch the toggle switch to position SD card. Now all new photos and videos will be recorded directly to external storage.
| Parameter | Internal memory | SD card |
|---|---|---|
| Write speed | High (UFS) | Depends on card class |
| Volume | Limited (32 GB) | Up to 512 GB |
| Risk of loss | Low | Medium (when extracted) |
| Availability | Only on phone | On any device |
It is worth considering that the writing speed on cheap memory cards may be lower than on the built-in chip. When shooting high-definition video 4K or when shooting frames continuously, there may be delays or interruptions in recording.
⚠️ Attention: If you take photos in RAW format or record 4K video, use only U3 or V30 speed class cards, otherwise the camera may automatically switch to internal memory.
Moving applications to external storage
The situation with moving applications to the Samsung A10 is more complicated. Modern versions of Android limit the ability to install apps on the SD card for security and system stability reasons.
However, some applications support the move function. Go to Settings → Applications, select the desired app and find the “Memory” item. If the “Change” button is active, you can move the application to the card.
Why can’t you transfer all applications?
Android developers have prohibited the complete transfer of system and important applications to external drives, since removing them can lead to system instability or loss data.
Even if an application is moved, some of its data and cache files often remain in the internal memory. This means that you won't be able to free up space completely, but you will gain a few megabytes.
- 📲 Go to settings and open the list of all applications.
- 🔍 Find a heavy game or app that takes up a lot of space.
- 💾 Click "Change" and select SD card if option available.
- 🔄 Repeat the procedure for other supported apps.
For messengers such as WhatsApp or Telegram, it is better to use the built-in cleaning tools or transfer media files manually, since transferring the application itself rarely gives a significant result.
Working with files through “My Files”
Built-in file manager My files is a powerful tool for manually sorting data. You can use it to move documents, downloads and music.
Open the application and select “Internal storage”. Find the folder Download, where files from the browser usually go. Select unnecessary documents or those that can be stored externally, and select “Move.”
Create a structured folder system on the memory card, for example, dividing the content into “Documents”, “Music” and “Archive”. This will help you quickly find the files you need in the future.
☑️ Check before transfer
Use the “Copy” function instead of the “Move” function if you are afraid of losing important data in the process. After successfully checking the copies, the originals can be deleted.
Typical errors and ways to solve them
When working with external drives, users often encounter read or write errors. Most often, the problem lies in the incompatibility of the file system or damage to the card.
If the phone no longer sees the card, try removing it, wiping the contacts and inserting it again. Restarting the device will also help. If the error recurs, the drive may be physically damaged.
⚠️ Attention: Interfaces and menu names may vary slightly depending on the version of the One UI shell and the year of manufacture of the specific modification of Samsung A10.
Some applications may stop working correctly if their data was forcibly moved to the card. In this case, return the application to the internal memory through the settings.
- ❌ "The file is damaged" error - the card needs to be formatted.
- 🐌 Slow operation - the card has a low speed class.
- 📉 Applications crash - the data was moved incorrectly.
- 🔒 The files are not readable - check the file system format (exFAT/FAT32).
Regularly check the status of the memory card through the storage settings in order to detect errors in time and save the data.
Regular backup of important data to a computer or to the cloud is the only guarantee of information safety when using external memory cards.
FAQ: Frequently asked questions
Is it possible to transfer all applications to a memory card in Samsung A10?
Unfortunately, no. Android system limitations and Samsung security policies prevent most modern applications from being fully portable. Some data always remains in the internal memory.
What is the maximum card size that the Samsung A10 supports?
Officially, the device supports microSD cards up to 512 GB. The use of cards with a larger capacity is possible, but is not guaranteed by the manufacturer.
Will Google Pay work if applications are on the card?
Banking applications and payment systems require high security. If an application is transferred to the card, it may stop working or require constant confirmation, since external drives are considered less secure.
How to get files back if I sold the phone?
Simply remove the memory card before selling the device. All files saved on it will remain with you, and you can insert the card into a new phone or read it through a card reader.
