Smartphone Samsung Galaxy A30s, released at the end of 2019, still remains a popular device due to its high-quality AMOLED screen and autonomy. However, owners of this model often face the same problem: lack of built-in storage. The basic version of the device usually has 32 or 64 GB of memory, a significant part of which is occupied by system files and pre-installed software. When free space runs out, the phone starts to work slower, and new applications stop being installed.
The situation is aggravated by the fact that modern instant messengers and social networks consume gigabytes of space in a matter of months of use. Telegram cache, WhatsApp stories and saved videos from TikTok can quietly “eat up” all available resources. In this article, we will look at not only standard cleaning methods, but also specific shell settings One UIthat will help restore the device to its former speed.
You will learn how to safely remove system junk, transfer data to a memory card and disable unnecessary Google services that run in the background. Proper organization of data storage will allow you to use your smartphone comfortably for a long time, without resorting to radical measures like resetting to factory settings.
Analysis of storage fullness through system settings
Before deleting files at random, you need to understand what exactly is taking up usable space. The shell One UI from Samsung implements a fairly detailed memory monitoring tool. Go to menu Settings → Device maintenance → Memory. Here you will see a color chart where applications, images, videos, audio and documents are indicated in different colors.
Click on a section Applicationsto see a list of apps sorted by the amount of space they occupy. It often turns out that it is not games that are leading, but social networks or browsers. The system will show not only the size of the application itself, but also the amount of data, as well as the size of the cache. It is the cache that can often be safely cleared, freeing up hundreds of megabytes.
Pay attention to the section Other or System. If this partition is bloated to an incredible size (for example, it takes up more than 10 GB), this may indicate an indexing error or accumulation of update logs. In such cases, simply rebooting the device sometimes helps the system recalculate the actual amount of occupied space.
⚠️ Attention: Do not try to delete files from system folders through third-party file managers with root access if you are not sure of their purpose. This may result in malfunction Samsung Galaxy A30s and loss of warranty.
Use the built-in "Clean Now" function in the device maintenance menu to quickly delete temporary files that do not affect system operation, but take up space.
Managing cache and heavy data applications
The fastest way to free up space is to work with the cache of popular instant messengers. Applications like Telegram or Viber save all viewed photos and videos to internal memory. Go to the settings of the messenger itself, find the “Data and Memory” section and use the built-in clear cache button. This will delete temporary files, but save your correspondence.
For other applications, the path will be as follows: Settings → Applications. Select the desired app from the list. Here you will see two important buttons: Clear cache and Clear data. The first deletes temporary files (safe), the second resets the application to the state “as after installation” (you will lose logins and settings).
Pay special attention to the browser Chrome or Samsung Internet. They accumulate gigabytes of site cache. Regularly clearing history and website data in your browser settings can return between 500MB and 1GB of free space. This is critical for devices with a small amount of built-in memory.
- 🗑️ The application cache can be cleared regularly without fear of losing personal data.
- 📱 Application data deletes your accounts and settings within the app.
- 🚀 Clearing the browser cache speeds up page loading and frees up space.
Transferring media files and using a microSD card
Samsung Galaxy A30s equipped with a slot for microSD memory cards, which is a huge advantage. You can transfer all heavy files (photos, videos, music) to external storage, leaving the internal memory exclusively for applications. Insert a card with a capacity of 32 to 512 GB and format it as portable storage.
To transfer files, open the application My files. Go to the Internal memorysection, select the folders DCIM (photo from the camera), Pictures (screenshots and images from social networks) and Download. Press the menu (three dots) and select Move, then select your SD memory card.
It is important to set the camera so that new pictures are immediately saved to the card. Go to the application Camera, click on the settings gear and find the item Save location. Switch it to SD card. Now all new photos and videos will be automatically recorded to external storage without clogging up the system partition.
| Data type | Recommended location storage | Impact on speed |
|---|---|---|
| Photo and Video | SD card (Class 10/U3) | Minimum |
| Applications | Internal memory | Critical (they work slower on SD) |
| Music | SD card | Absent |
| Documents | SD card or Cloud | Absent |
⚠️ Attention: Not all applications can be transferred to a memory card. System restrictions Android and developer policies often prohibit installing heavy games on external media to ensure stable operation.
☑️ Preparing to transfer files
Optimizing the operation of cloud services and galleries
If you don’t want to buy a memory card, using cloud storage is an excellent solution. The service Google Photos allows you to store pictures in the cloud, deleting their local copies from the phone. Turn on the “Free up space” function in the application settings to automatically delete photos from your device that have already been uploaded to the cloud.
It is also worth checking the synchronization settings in your account Google. Go to Settings → Accounts and Backup → Account Management. Select your Google account and see what exactly is synced. Disabling synchronization of unnecessary services (for example, Google Drive or Google Journal) will prevent unnecessary data from being downloaded to the phone.
Owners Samsung can use the proprietary cloud, although its free limit limited. However, for important documents this may be sufficient. The main rule: do not store files on your device that you only need occasionally. Archive them and send them to the cloud or to your computer.
How does the Free Up Space feature in Google Photos work?
When you press this button, the app checks which photos and videos are already safely saved in your Google cloud account. Once confirmed, it deletes local copies of these files from the phone's internal storage, leaving only thumbnails for viewing. The originals are always available via the Internet.
Removing pre-installed software and system updates
Smartphones Samsung often come with a set of pre-installed applications that cannot be removed in the usual way. However, they can be disabled, which will hide them from the menu and stop background activity, although they will still take up space. Go to Settings → Applications, find unnecessary software (for example, duplicate browsers or Microsoft services) and click Disable.
A more radical method is to remove system application updates. If some standard application (for example, Samsung Pay or Bixby, if you do not use them) takes up too much space after the update, go to its settings and select Uninstall updates. This will return the application to the factory version, which takes up minimal space.
Also check your downloads folder. Often installation files accumulate there .apkthat have already been installed but not deleted. The file manager My files → Downloads will help you find and remove this digital junk.
- 📦 Disabling applications stops them from working, but does not delete the files.
- 🔄 Removing updates returns the application to its original one size.
- 📂 Regularly check the Download folder for old installers.
⚠️ Attention: The interface and names of menu items may vary slightly depending on the firmware version One UI. If you do not find an exact match, look for similar sections in the settings.
Disabling unused system applications and services (for example, Bixby) not only frees up RAM, but also prevents background data loading, saving battery power.
Usage maintenance mode and reset settings
If all of the above methods did not help and the phone continues to report low space, the system may have accumulated deep errors or data fragmentation. In this case, you can use recovery mode. Turn off the phone, then hold down the buttons Volume Up + Power (on a switched off device with a cable connected to the PC for new versions of Android) to enter Recovery Mode.
In the recovery menu, select item Wipe Cache Partition. This command clears the system cache without affecting your personal data, photos and applications. This is a safe procedure that is recommended after major system updates.
The last resort is a full reset to factory settings (Factory Reset). Before doing this, be sure to back up all important data to your computer or to the cloud. After the reset, the phone will be like new, with the maximum amount of free memory. This is the most effective way to restore performance to your old device.
Path to reset: Settings → General settings → Reset → Data resetAfter resetting, do not rush to restore all applications at once. Install only the essentials and watch how quickly the memory fills up. This will help identify the “culprit” of the free space leak.
What is Wipe Cache Partition?
This is a section in the Android recovery menu designed to delete temporary system files. Unlike a hard reset, this operation does NOT delete your photos, contacts, or installed apps. It helps solve problems with freezing after updating the system.
Is it possible to remove Samsung system applications without root access?
You cannot completely remove system applications without root access, but you can disable in the settings. This will hide the icon and prevent the application from launching, but the files will remain physically on the system partition. To completely remove it, you need to connect to a PC and use ADB commands.
Why does the memory fill up by itself after cleaning?
Most likely, you have automatic media downloading enabled in instant messengers (Telegram, WhatsApp). Check the settings of these applications and disable autosaving of photos and videos to the gallery. Also, the system may be clogged with error logs if some application does not work correctly.
Is it safe to use cleaning applications from the Play Market?
Most of these applications (Clean Master and analogues) are more harmful than useful. They themselves consume resources, show ads and often delete only shortcuts and not actual files. The built-in cleaning tool Samsung is quite enough for safe maintenance.
How to transfer applications to an SD card on Samsung A30s?
Go to Settings → Applications, select the desired application. If the developer has allowed the transfer, there will be a button Memory, and in it an option Change → SD card. If there is no button, then the application technically does not support work from external media.
What to do if the phone writes “Memory full”, although there is space?
This is a common file system bug. Try rebooting your phone. If that doesn't help, connect your phone to your computer in file transfer mode and manually delete a few large videos, then empty the trash (if you have one). In extreme cases, formatting the SD card will help.
