Smartphones of the Samsung Galaxy A6series, released in 2018, are still popular due to their AMOLED screens and balanced characteristics. However, the built-in storage capacity of 32 or 64 gigabytes in modern realities fills up critically quickly. The Android operating system and pre-installed services One UI occupy a significant portion of the space, leaving the user with a limited amount of free space to install applications and store multimedia.
When the internal storage becomes full, the device begins to work slower, and some apps may stop running altogether. The system automatically blocks the ability to take new pictures or download updates, requiring immediate intervention. Freeing up memory becomes not just a desirable procedure, but a necessity for normal operation of the gadget.
In this material we will analyze effective and safe cleaning methods that will help restore the performance of your device. We will not use dubious accelerator apps, but will use standard system tools and proven methods of manual optimization.
Memory analysis and search for hidden volumes
Before you start deleting files, you need to understand exactly what is taking up space in your Samsung Galaxy A6. Standard Android tools often show the big picture, but hide the details of how data is distributed between applications and system folders. To begin, go to the settings menu, where you can see a visualization of the occupied space.
Click on the item Settings → Device maintenance → Memory. Here you'll see a breakdown by category: apps, images, videos, audio, and documents. Please note that the standard analyzer may not show the cache size of some messengers, which can reach tens of gigabytes.
⚠️ Attention: When analyzing the storage, keep in mind that the actual available memory is always less than that stated in the specifications. This is due to the fact that the file system and system partition occupy a fixed volume that is not available to the user.
For a more detailed study, you can use the built-in file manager My files. Go to section Storage analysisto see a list of the largest folders. Often, users forget about downloaded files in a folder Download or backups created by third-party applications.
Clearing cache and temporary application files
Most An effective way to quickly free up space is to clear cached data. Cache are temporary files that applications create to speed up their work, but over time they bloat and begin to take up valuable space. Unlike user data, deleting the cache does not result in the loss of logins or game progress.
To clear it, go to Settings → Applications. Choose the app that takes up the most space (often YouTube, Instagram, or browsers). Click on the item Storage, and then select the button Clear cache. It is important not to confuse this option with the “Clear Data” button, as it will delete all application settings.
☑️ Cache clearing plan
You can also use the quick cleaning function in the device maintenance menu. Click Settings → Device maintenance → Memory → Clear now. The system will automatically detect temporary files that are safe to delete and offer to erase them. However, the manual method through application settings often gives the best result, as it allows you to control the process for each specific software.
Managing media files and optimizing the gallery
Photos and videos are the main consumers of free space on any modern smartphone. The camera Samsung A6 takes high-quality pictures that take up a significant amount of space, especially if high-resolution recording is enabled. Regular revision of the gallery and transfer of archives to external media or to the cloud is a mandatory stage of optimization.
Use the “Delete similar” function or built-in sorting tools in the Gallery application. Often, thousands of unnecessary images accumulate in the “Screenshots” or “Uploaded” album, which can be deleted in batches. Also check the folder Trash in the gallery, as deleted files can be stored there for up to 30 days, continuing to take up space.
Secret menu for clearing duplicates
Some versions of One UI have a hidden duplicate search feature. To activate it, you may need to update the Gallery application through the Galaxy Store or use developer mode to display system albums.
| File type | Medium size | Recommendation |
|---|---|---|
| Photo (JPEG) | 3-5 MB | Compress or delete old ones |
| Video (Full HD) | 150-200 MB/min | Transfer to PC or cloud |
| RAW photo | 25-30 MB | Keep for editing only |
| Screenshots | 1-2 MB | Delete immediately after use |
To automate the process, you can set up synchronization with Google Photos or Samsung Cloud. After successfully uploading the originals to the cloud, use the “Free up space” function, which will delete local copies from the device, leaving them available for viewing via the Internet.
Working with instant messengers: Telegram and WhatsApp
Messengers have long ceased to be just text chats and have turned into media harvesters that save every sent image and video to the device’s memory. In WhatsApp i Telegram by default, auto-saving of all incoming files is enabled, which quickly leads to the storage capacity being full. Here you can limit the cache size, for example, to 1 GB, and set up automatic cleaning of old files. Set an auto-delete timer for media files: photos can be deleted after 3 days, and videos after 1 day. This will not delete them from the chat, but will remove the local copy from the phone. Samsung A6.
In Telegram settings go to Data and memory → Memory usage. Here you can limit the cache size, for example, to 1 GB, and set up automatic cleaning of old files. Set an auto-delete timer for media files: photos can be deleted after 3 days, and videos after 1 day. This won't remove them from the chat, but it will remove the local copy from your phone.
⚠️ Attention: The messenger settings interface may change after updates. If you do not find the specified items, look for the “Storage” or “Cache” sections in the general application settings.
For WhatsApp, the path is slightly different: Settings → Data and storage → Storage management. Here the application itself will show a list of chats that take up the most space and allow you to selectively delete large files. Users are often surprised to find that old correspondence with friends takes up several gigabytes due to thousands of sent pictures.
Enable the “Auto delete media” option in the Telegram settings for all chats. This will prevent the accumulation of debris in the future and save you time on manual cleaning.
Using a microSD memory card for expansion
The model Samsung Galaxy A6 is equipped with a slot for microSD memory cards, which is an excellent solution to the problem of lack of space. By transferring media files and some applications to an external card, you will free up precious internal storage for system operation. However, it is important to configure the device correctly so that it uses the card by default.
After installing the memory card, the system will prompt you to select a method of use. Select "Use as portable storage" if you plan to transfer the card to other devices, or "Use as internal storage" for full integration (although this feature may be limited on newer versions of Android). To transfer files, open My files, select internal memory, long-press the desired file or folder and select Copy or Move.
Using a fast UHS-I or UHS-II class memory card is critical for stable operation of applications running from an external drive.
Not all applications can be transferred to a memory card, as this depends on the software developer. However, photos, music and documents should be stored there. It is also recommended to change the default save path in the camera settings: Camera settings → Save location → Memory card.
Removing unused applications and system junk
Samsung devices often come with a lot of apps pre-installed that you may never use. Not only do they take up space, but they can also consume resources in the background. Review the installed software and remove all unnecessary items.
Go to Settings → Applications and sort the list by size or date of last use. If you see a game you haven’t played for six months, or a service you don’t use, feel free to delete it. For system applications that cannot be deleted, use the Disable feature, which will hide them and stop associated processes.
⚠️ Attention: Be careful when deleting applications with names containing the words "System", "Framework" or "Service". Removing critical system components can lead to unstable operation of the smartphone.
Hidden system files
Even after deleting applications, empty folders with their names may remain. Use a file manager to find and delete these orphaned directories manually.
FAQ: Frequently Asked Questions
Is it safe to use third-party memory cleaning apps like Clean Master?
Using aggressive cleaners on modern versions of Android often does more harm than good. They can delete necessary cache files, forcing apps to download them again, which wastes bandwidth and battery. The built-in tools Samsung Galaxy A6 are quite enough to maintain order.
Why does the memory quickly fill up again after cleaning?
This is normal system behavior. Applications constantly create new temporary files, browser caches grow when visiting sites, and instant messengers save new messages. It is recommended to carry out preventive cleaning once every 1-2 weeks, and not wait for critical filling.
Is it possible to transfer all applications to a memory card on a Samsung A6?
No, this possibility depends on the developer of the specific application and the version of Android. Many modern applications require high read/write speeds, which are provided only by internal drives, so the system prohibits transferring them to external cards.
What should I do if the system writes “Memory full” even though I have deleted everything?
Try to restart the device. Sometimes the file system does not update the free space index immediately after a large delete. Also check the folder .Trash or Trash in the gallery and file manager, files there are still taking up space.
