Owners of smartphone series Samsung Galaxy A6 often face a situation when the internal storage is full and the system starts to work slower. This is a natural process of operation Android devices, especially models with a memory capacity of 32 or 64 GB, which after a couple of years of active use seems meager. The accumulation of temporary files, application caches, high-resolution photos and system updates creates a critical mass of data that requires immediate intervention.
There are many ways to return the gadget to its former agility, ranging from the banal deletion of photos to deep cleaning of system garbage. Memory optimization not only frees up space for new apps, but also significantly extends the service life of the drive, preventing its wear and tear from constant rewriting operations. In this article, we will look at proven methods that will help you safely free up gigabytes of space.
Before taking drastic measures like resetting settings, it is worth trying less painful but effective built-in system tools. Proper file management allows you to keep your device in good shape without losing important data. Next, we will look at step-by-step action algorithms.
Storage usage analysis and system tools
The first step should always be diagnosis. You need to understand exactly what takes up the lion's share of your space. The operating system One UI ot Samsung has a built-in powerful monitoring tool that visualizes the distribution of data. Go to the menu Settings → Device maintenance → Memoryto see detailed statistics.
The system automatically categories files, showing the space occupied by applications, images, videos, audio and documents. Users are often surprised to discover that a significant portion is occupied by messenger data or the cache of streaming services. The system “Other” partition can hide up to 10-15% of the memory, and cleaning it often requires manual intervention through the file manager.
Use the built-in optimization function by clicking the “Optimize Now” button. This algorithm safely removes temporary files, irrelevant remnants of deleted applications, and rarely used software. However, you should not rely only on the automatic mode, since it does not affect the user’s personal files.
⚠️ Attention: Automatic optimization does not delete your personal photos or documents, but before any manipulations with system files, it is strongly recommended to create a backup copy of important data.
Clearing cache and application data
The most effective way to quickly free up space is to work with the cache applications. Cache - these are temporary files that speed up the launch of apps, but over time they swell to gigantic sizes. This is especially true for social networks and browsers that store thousands of thumbnails of images and videos.
To clear, go to Settings → Applications. Select a demanding application (such as YouTube, Instagram or Chrome) and click "Storage". Here you will see two buttons: “Clear cache” and “Clear data”. The first is safe and deletes only temporary files, the second will return the application to the state immediately after installation, deleting logins and settings.
- 📱 For messengers like WhatsApp and Telegram, it is better to use the built-in cleaning settings inside the application itself, since system cleaning can delete important correspondence databases.
- 🗑️ Regularly clearing the browser cache (Chrome, Samsung Internet) can free up from 500 MB to 2 GB of space.
- ⚙️ The “Delete unused applications” function in the device maintenance menu will help you quickly find apps that you have not used for the last 3 months.
☑️ Weekly cache clearing
Do not ignore background processes. Some applications continue to accumulate error logs even when minimized. Periodically forcing such apps to stop via the developer menu or task manager helps keep them clean, which indirectly affects the speed of the file system. Working with the gallery and cloud storage Media files traditionally take up the most space on a smartphone. The camera RAM clean, which indirectly affects the speed of the file system.
Working with the gallery and cloud storage
Media files traditionally take up the most space on a smartphone. Camera Samsung Galaxy A6 is capable of taking high-quality pictures, but modern processing algorithms create large files. Video in resolution 1080p at frequency 30 fps can “eat up” about 150 MB per minute of shooting.
Use the “Cloud Thumbnails” function in the Google Photos or Samsung Gallery application. This mechanism replaces the original photos on the device with their smaller copies, storing the full versions in the cloud. When viewing a photo, it is loaded in original quality over the network, but takes up 10-20 times less disk space.
| File type | Average size | Recommended action |
|---|---|---|
| Photo (JPEG/HEIC) | 3-8 MB | Transfer to the cloud, remove duplicates |
| Video (Full HD) | 150-200 MB/min | Compression or transfer on PC |
| Selfie animation | 15-30 MB | Deletion after saving to the cloud |
| RAW (DNG) | 25-40 MB | Processing and deletion from the phone |
It’s also worth checking the “Trash” folder in the gallery. Deleted files are often kept there for another 30 days, taking up precious space. Emptying the Trash is an instant way to get a few gigabytes back. Don’t forget about the folder Downloadwhere APK installation files and documents from the Internet are accumulated.
Enable the “Data Saving” mode in the camera settings so that videos take up less space without critical loss of quality for viewing on the smartphone screen.
Using a microSD memory card
The model Samsung A6 is equipped with a slot for memory cards, which is a salvation for owners of versions with 32 GB of internal memory. Proper use of an external card allows you to transfer all media content and even some applications outside the system partition.
To transfer data, go to Settings → Device Maintenance → Memory and select the option to change the default storage location. The system will offer to transfer photos, videos and documents to the SD card. This frees up the internal NAND drivewhich works faster and is critical for system operation.
- 🚀 Use UHS-I Class 10 or higher cards to do not slow down the smartphone when reading data.
- 📂 Set up the camera so that new photos and videos are saved directly to the memory card, bypassing the internal storage.
- ⚠️ Do not store system files or application data that require high response speed on the memory card, otherwise interface lags may occur.
⚠️ Attention: Memory cards have a limited rewriting resource. Do not use cheap cards from unknown brands for constant system operation, as their sudden failure can lead to data loss.
How to format a card as internal memory?
In older versions of Android there was a “Merge Memory” option, but in modern One UI shells this function is often hidden or missing. Forced formatting via ADB is not recommended as it may cause the phone to become unstable and void the warranty. It is better to use the card simply as additional storage.
Removing system garbage and residual files
Even after deleting applications, “tails” remain on the phone - empty folders, logs and configuration files. To find them, you will need a file manager, for example Files by Google or the built-in “My Files”. You need to look for folders with the names of deleted apps.
Pay special attention to the folder Android/data. Cache files of games and heavy applications are stored here. If you deleted a game, but the folder with its name (often containing obb or cache) remains, you can safely delete it manually. This can free up several gigabytes.
It’s also worth checking your messenger folders. WhatsApp, for example, creates a separate folder for each chat with attachments. Often there are videos there that you have already watched and don’t need. In the WhatsApp settings there is a “Storage Management” function that shows the “heaviest” chats.
Manually checking folders in the file manager allows you to find hidden gigabytes of garbage that automatic cleaners miss.
Radical measures: Reset to factory settings
If none of the above methods gave the desired result and the memory continues to rapidly fill with incomprehensible data, the system may have accumulated critical file system errors. In this case, a full reset helps (Factory Reset).
This procedure returns the phone to the “as from the store” state, deleting absolutely all user data, applications and settings. Before doing this, be sure to make a full backup through your account Samsung Cloud or Google Drive. Path to reset: Settings → General settings → Reset → Data reset.
After a reset, the phone will work as quickly as possible, since the file system will be cleared of fragmentation and logical errors. This is often a “second wind” for devices that are 3-4 years old.
Is it safe to use third-party cleaning applications?
Most popular cleaners (Clean Master and analogues) in modern versions of Android have limited access rights. They can't remove system junk any deeper than Samsung's built-in tool can. Moreover, such applications themselves consume battery and RAM resources while running in the background. It is better to use built-in tools or proven file managers.
Why does the memory fill up again immediately after cleaning?
This is normal system behavior. Applications create new temporary files for their work. If the memory fills up critically quickly (in a few hours), check whether there is a cyclic error logging process running in the background or whether some application is loading files endlessly (for example, a bot in Telegram).
Is it possible to transfer all applications to a memory card?
In modern versions Android and the One UI shell, the ability to transfer applications to an SD card is often blocked by developers for the sake of system stability. You can transfer only part of the data (photos, music), but not executable app files, except in rare cases when this function is supported by a specific application.
What to do if the system writes “Memory full”, although there is space?
This may be an error in indexing media files. Try rebooting the device in safe mode or clearing the cache of the Media Scanner application. Also check if the system log section is full, which sometimes happens when updates fail.
