Smartphone owners Samsung Galaxy A30 often face a situation when the device starts to work slower, applications open with a delay, and the system persistently reports a lack of space. This is a natural process for gadgets that are actively used for a long time. The internal storage is filled with temporary files, remnants of deleted apps and multimedia content that we forget to delete.
The model Galaxy A30, despite its advantages, has a limited amount of built-in memory in basic versions, which makes the issue of cleaning it critical for stable operation. Understanding exactly where digital “junk” accumulates and how to properly remove it will extend the life of your device without the need to buy a new one. In this article, we'll look at all the effective methods for freeing up space, from simple built-in tools to deeper cleaning of system partitions.
Before taking drastic measures like resetting your settings, it's worth trying a comprehensive approach to file management. Competent Storage optimization will not only restore performance, but also free up space for new photos and applications. Let's look at the main tools and methods available in the One UI shell.
Using the built-in device optimizer
The Company Samsung has provided a powerful built-in tool for system maintenance in its shell. It allows you to automatically analyze the status of memory, processor and battery. To get started, you need to go to Settings → Device maintenance → Memory. Here the system will show how much space is available and how much is occupied, and will also suggest optimizing the use of resources.
The “Clean Now” function will delete temporary files and unnecessary data that do not affect the operation of applications. However, it is worth understanding that this is only superficial cleaning. A more in-depth analysis can be carried out by clicking on the “Memory” button in the maintenance menu. The system will show a list of categories that take up the most space, which will help you understand where exactly the free space is going.
It is important to note that the built-in optimizer does not always remove the cache of heavy applications completely. It focuses on files that are safe to delete without losing user data. For more thorough cleaning, manual intervention in the settings of specific apps will be required.
⚠️ Attention: Built-in optimization may not delete messenger cache files (WhatsApp, Telegram), since they are considered user data. They must be cleaned separately within the applications themselves.
Regular use of a standard maintenance tool helps keep the system in good shape. This is especially true for the model A30, which may experience a lack of RAM when several heavy tasks are running simultaneously. Do not ignore system notifications about the need for cleaning, as they appear precisely when free space reaches a critical minimum.
Analysis and removal of large files and applications
The most effective way to quickly free up gigabytes of space is to find and remove unnecessary large files. The menu Settings → Device maintenance → Memory often displays a list of applications that take up the most space. Social networks, navigators and games with heavy textures are often in the top.
Not all applications are equally important. You could install many of them “once” and forget about them. Removing such apps is the first step to freedom. It is also worth paying attention to the “Downloads” section, where there may be old APK installation files that are no longer needed after installing the apps.
To manually search for large files, you can use the standard “My Files” explorer. Go to the Storage Analysis category or simply sort the files by size. Often, users find forgotten high-resolution videos or archives of documents that can be transferred to a computer or to the cloud.
- 📸 Gallery: Check the “Trash” folder, it can take up to 30 days of space, storing deleted photos.
- 📱 Messengers: WhatsApp and Telegram save all received photos and videos to the phone’s memory by default.
- 🎮 Games: The game cache can weigh several gigabytes, even if the application itself is deleted (residual files).
- 📥 Downloads: The Download folder is often full of PDF files and pictures from the browser.
Pay special attention to video files. One minute 4K video can take up more space than a thousand documents. If your Samsung Galaxy A30 has little internal memory, storing videos in original quality will quickly lead to its overflow. It is recommended to set the camera to record in Full HD if 4K is not critical, or immediately transfer the video to external storage.
Use the Google Files app to find duplicate files. It can find identical photos and videos that you may have accidentally saved several times.
Working with application caches and system garbage
Cache is temporary data that applications save for faster loading. Over time, the cache can grow to enormous sizes. For example, the cache of YouTube or the Chrome browser can reach 1-2 GB. Clearing the cache does not delete your personal data, logins, or passwords, but it does return the application to a "as-installed" state in terms of temporary files.
To clear the cache of a specific application, go to Settings → Applications. Select the desired app from the list (for example, Instagram or TikTok). Click on "Memory" or "Storage" and then select the "Clear Cache" button. Do not confuse it with the “Clear data” button, which will reset the application settings and require re-authorization.
System garbage also accumulates during operation of the operating system Android. These may be error logs, temporary update files, and remnants of uninstalled apps. You can use Recovery Mode to remove them, but this requires caution. A safer way is to use the "Safe Mode" mode to identify problematic applications that bloat the cache.
| Data type | What is it | Can I delete | Consequences |
|---|---|---|---|
| Cache applications | Temporary files to speed up work | Yes, safe | The application may take a little longer to load when first launched |
| Application data | Settings, logins, saves | Only if you don’t mind resetting | Full reset of the application to factory settings |
| Cookies | Data about visiting sites | Yes | It will be necessary again log into websites |
| Downloads | User-downloaded files | Only unnecessary ones | Deleting important documents or photos |
Regularly clearing the cache is a good habit, but doing it there is no point every day. It is enough to carry out the procedure once a month or when you notice that a particular application is unstable. For social networks, clearing the cache is often the only way to free up space without deleting the application itself.

Using a microSD memory card for expansion
Smartphone Samsung Galaxy A30 equipped slot for microSD memory cards, which is a salvation for models with a small amount of built-in storage. Correctly setting up a memory card allows you to transfer photos, videos and even some applications to it, freeing up precious internal space.
After installing the memory card, the system will offer to use it as “Portable storage” or “Internal storage”. For Galaxy A30 it is better to choose the first option, as it provides better compatibility. In the second option, the card is encrypted for a specific phone and will not work on other devices without formatting.
It is important to configure the camera and instant messengers so that they save new files directly to the memory card. In the camera settings, select Settings → Storage location → SD card. For WhatsApp, the path for saving media files changes in the settings of the application itself in the “Data and Storage” section.
⚠️ Attention: Memory cards have lower read and write speeds compared to internal memory. It is not recommended to transfer heavy games or applications that require high response speed to them, as this can lead to slowdown of the interface.
If you are using a memory card, check it regularly for errors. The file system of microSD cards is prone to fragmentation and errors when overwritten frequently. Periodically formatting the card (after saving the data on a PC) will help maintain its performance at a high level.
Which memory card to choose for the Samsung Galaxy A30?
It is recommended to use UHS-I speed class cards (U1 or U3) from trusted brands (Samsung, SanDisk, Kingston). The card capacity can reach 512 GB or even 1 TB, which is officially supported by this model. Avoid cheap cards without a name, as they can quickly fail and damage data.
Cleaning multimedia in the gallery and instant messengers
The main memory consumer in modern smartphones are photos and videos. The Gallery application on Samsung has a convenient sorting function by file size. Go to the gallery menu, select sorting and find the heaviest videos. These are often long screen recordings or blurry videos shot in the dark.
Messengers like WhatsApp create separate folders in the gallery where all sent and received images go. Even if you delete a photo in a chat, a copy of it may remain in your phone's memory. WhatsApp can be set to automatically clean up media files, or you can manually go to the Storage tab in the app's settings and delete large files.
Cloud services such as Google Photos or Samsung Cloud offer a "Free up space" feature. It deletes from the device those photos and videos that have already been successfully uploaded to the cloud. This is a safe way to save memory while leaving access to the archive via the Internet.
- 🗑️ Screenshots folder: Screenshots are often forgotten to be deleted; they accumulate over the years.
- 📹 Video from messengers: Automatically downloaded videos from Telegram channels take up a lot of space.
- 📸 Burst shooting: Check albums with serial photos, often there are good shots there, and the rest can be deleted.
- 🎵 Offline music: Check the Spotify or Yandex.Music applications for downloaded playlists, if you you don’t use them.
Don’t forget to check the “Recently Deleted” folder. Files are stored there for 30 days and continue to take up space. If you are sure that you have deleted unnecessary things, go to this folder and clean it completely. This is instantly returned space.
Automatically uploading photos to the cloud and then deleting local copies is the most effective way to permanently solve the problem of lack of space for multimedia.
Radical measures: resetting and formatting
If none of the above methods helped and the memory fills up on its own, perhaps The system has accumulated critical errors or malware. In this case, the only effective solution is a complete reset (Hard Reset). This procedure will return Samsung Galaxy A30 to the factory state.
Before performing a reset be sure to create a backup copy all important data. Use Samsung Smart Switch on your computer or Samsung/Google cloud account. After the reset, all data, including contacts, messages and files, will be permanently deleted.
To perform a reset, go to Settings → General settings → Reset → Reset data. The system will warn you about the consequences. After the reboot, the phone will be as good as new, and you will have to set up accounts and install applications again. This is guaranteed to remove all software junk.
⚠️ Attention: Before resetting, make sure that the battery charge is at least 50-60%. Interrupting the reset process due to a low battery may damage the system partition and make it impossible to turn on the phone.
After the reset, do not rush to install all applications at once. Try using a “clean” phone for a couple of days. This will help you understand which application or activity is causing your memory to fill up quickly in the future. Often the problem lies in one specific application with a memory leak.
What to do if the memory fills up immediately after a reset?
If immediately after a reset and a minimum set of applications, the memory quickly fills up again, the problem may be hardware. The memory chip may be worn out or the controller may be faulty. In this case, diagnostics are required at a service center.
Frequently asked questions (FAQ)
Is it possible to delete files from the Android folder on Samsung A30?
The folder Android application data is stored in the folder. You can only delete the contents of subfolders cache inside specific application folders. Deleting the folder data will lead to a reset and loss of progress in games and applications. Be extremely careful when manually cleaning this directory through the file manager.
Why does the memory fill up even if I don’t download anything?
This may be due to the work of instant messengers that automatically download media files from groups and channels. Also, the reason may be system logs that grow due to errors in the OS, or the cache of streaming services (YouTube, Netflix), which is not cleared automatically. Is it safe to use cleaning applications from Google Play? The built-in optimization tool
Is it safe to use cleaner apps from Google Play?
Most of these applications (Clean Master and analogues) consume resources themselves and display advertisements. Built-in optimization tool Samsung is quite sufficient. Third-party cleaners can aggressively unload processes from RAM, which forces the system to waste more energy on starting them again.
How to transfer all applications to a memory card on the Galaxy A30?
It is impossible to completely transfer all applications, it depends on the developer. Some system and important applications should remain in the internal memory for stability. The transfer is available in the menu Settings → Applications → [Select application] → Storage → Edit → SD cardif the developer has enabled this function.
