Smartphones series Samsung Galaxy A5, despite their popularity and balanced characteristics, inevitably slow down over time. The main reason for the drop in performance lies not in the aging of the processor, but in the accumulation of digital “garbage” in the internal memory. When the storage is filled with residual files, application cache and duplicate photos, the system begins to work unstable, and the interface slows down.
Automatic cleaning utilities often act superficially, deleting only temporary files, but leaving deeply hidden system garbage. Manual cleaning allows you to take full control of the situation and free up gigabytes of valuable space. In this guide, we will examine how to clean an Android phone of unnecessary files manually using the example of a model Samsung A5using only built-in tools and safe methods for accessing the file system.
The process requires care, since you will be working with system directories directly. However, by following the step-by-step guide, you can safely remove the excess without damaging the functionality of the device. Let's start by analyzing what exactly is taking up space on your device.
Analyzing occupied space and searching for heavy files
Before you start deleting, you need to understand the structure of memory filling. Owners Samsung A5 often encounter a situation where the memory is full, but visually they do not see large files. The Android system hides some directories from standard viewing, so it is important to use the right approach to analysis.
Go to the device settings and open the storage section. Here you will see a data distribution chart. Particular attention should be paid to the “Applications” and “Miscellaneous” categories. Often, it is in the “Miscellaneous” section where log files, remnants of deleted apps and temporary messenger data accumulate. File system Android is designed in such a way that deleting an application does not always guarantee complete cleanup of its folders.
For a more detailed analysis, it is recommended to use the built-in file manager My Files (My files), which is preinstalled on all devices Samsung. It allows you to sort data by type, size and date modified. This is a critical step, since deleting a random system file can lead to errors in the operation of the OS.
⚠️ Attention: Never delete files from the Android root folder or system directories unless you know exactly their purpose. Deleting libraries may cause the phone to stop booting.
Clearing application caches and system services
Cache is temporary data that applications save to speed up their work. Over time, the cache size can reach several gigabytes, especially in social networks and browsers. Clearing the cache is the safest way to free up space as it does not delete your personal data, logins or passwords.
To perform a deep clean, go to Menu Settings → Applications. Here you need to sort through resource-intensive apps one at a time. Select an application, for example YouTube or Instagram, and click on “Storage”. You will see two buttons: “Clear data” and “Clear cache”. We are interested in the second option.
On devices Samsung Galaxy A5 there is also a function to clear the cache of all applications at once through Recovery Mode, but the manual method through the settings is preferable. It allows you to control the process and avoid deleting important temporary files that the system may need right now for the correct operation of background services.
- 🗑️ Browser cache: Often takes up to 500 MB, contains thumbnails of sites and scripts.
- 📸 Camera cache: Can store thumbnails of deleted photos and HDR processing data.
- 💬 Messenger cache: The heaviest category, including viewed media files from chats.
Periodically clear the cache of your Chrome or Samsung Internet browser - this will not only free up space, but will also speed up page loading, forcing browser to download the latest versions of sites.
Working with the Download folder and duplicate media
The Download (Downloads) folder is the most popular place for unnecessary files to accumulate. Users often download installation APK files, documents, presentations and pictures, which after use lose their relevance, but continue to remain in memory for years.
Open the file manager and go to the directory Internal memory → Download. Please review the contents carefully. Delete all application installation files with the extension .apk —if the application is already installed, this file is no longer needed. Also check your documents folder and delete old versions of files, leaving only current ones.
Duplicates of photos and videos deserve special attention. When actively using the camera and synchronizing with cloud services, copies of images can be created. Use the sort by size function in the file manager to find identical video files that may be duplicated in different albums.

| File type | Location | Recommendation |
|---|---|---|
| Installers (.apk) | /Download | Delete everything after installation |
| Thumbnails (.thumbnails) | /DCIM/.thumbnails | You can delete, the system will create new ones |
| Temporary files (.tmp) | Different folders | Safe removal |
| Error logs (.log) | /Android/data | Delete only old logs |
Deleting residual files after uninstallation
When you delete an application in the standard way through settings, empty folders or files are often left in memory configurations. These "tails" take up space and may conflict when the app is reinstalled. Android there is no built-in “remove all traces” button, so this is done manually.
Go to the root of the internal memory and pay attention to the folders with the names of deleted applications or developers. For example, if you deleted a game from Gameloft, the folder with this name may remain empty or contain a couple of megabytes of data. Feel free to delete such directories if you are sure that the app is no longer used.
Pay special attention to the folder Android/obb i Android/data. Cache files of heavy games and application data are stored here. If you deleted a game, but the folder with its name (for example, com.gameloft.android...) remains in the obbsection, you can delete it manually. This will free up a significant amount of space, which standard uninstallation often ignores.
Why do folders remain after uninstallation?
Application developers deliberately leave folders with data (saves, settings) in case the user decides to reinstall the application and does not want to lose progress. However, with manual cleaning, this data can be deleted permanently.
Cleaning hidden system folders and logs
In the Android system, there are hidden directories that are not displayed during normal browsing, but can grow to impressive sizes. To access them in the file manager Samsung you need to activate the display of hidden files through the Explorer settings menu.
One of the most “junk” is the folder .thumbnails inside the directory DCIM. Here the system stores thumbnails of all your photos and videos for quick display in the gallery. Over time, this file can weigh several gigabytes. Deleting it is safe: the next time you open the gallery, the system will create it again, but at an optimal size.
Also check the log folders in the system application directories. Files with the extension .log contain records about errors and system operation. If the phone is working stably, these files from previous months can be deleted. This action will not affect the current work operating system, but will clear space.
⚠️ Attention: The interface and folder paths may differ slightly depending on the version of the shell One UI or TouchWizinstalled on your Samsung A5. Always check the current menu view before deleting system files.
☑️ Manual cleaning checklist
Optimizing the operation of WhatsApp and instant messengers Telegram
Messengers are the main memory hogs on modern smartphones. WhatsApp and Telegram by default, they save all received photos, videos and documents to the phone’s internal memory, creating duplicates in their internal databases and in the general gallery.
In settings WhatsApp go to the “Data and Storage” → “Storage Management” section. Here you will see a list of chats sorted by the amount of space they occupy. You can selectively delete large video files or forwarded documents from specific conversations without deleting the conversation itself. This is more effective than completely clearing the cache.
For Telegram the situation is simpler due to the cloud-based nature of the messenger. Go to Settings → Data and memory → Memory usage. Set a cache size limit (for example, 200 MB) and click the "Clear cache" button. Important: turn on the “Auto-delete media” function so that the phone itself deletes old files without taking up space on Samsung A5.
- 📹 Video files: They take up up to 80% of the space in instant messengers, delete them first.
- 📎 Documents: PDF and archives are often saved automatically, check the Documents folder.
- 🖼️ Stickers and emoji: The graphics cache can take up hundreds of megabytes during active use.
Setting up automatic cache deletion in instant messengers is a one-time action that will save you from the need for manual cleaning in the future, keeping your phone in optimal condition automatically.
Frequently asked questions about cleaning Samsung A5
Safe Is it possible to delete the Android/data folder?
Completely deleting the entire folder Android/data is not recommended, since the settings of installed applications are stored there. However, you can safely delete subfolders of applications that you have already uninstalled, or clear the contents of cache folders inside this directory for heavy games.
Why did the space not free up after cleaning?
You may have cleared only the visible cache, but did not delete hidden log files or duplicates in the folder Download. Also check the trash in the gallery and file manager - on Samsung deleted files are stored there for another 30 days, continuing to take up space.
How to clear the cache of all applications at once?
On Samsung A5 you can boot into Recovery mode (by holding down the volume and power buttons) and select item Wipe Cache Partition. This will clear the system update cache and temporary OS files without affecting your personal data and photos.
Do you need to delete .nomedia files?
No, the files .nomedia are service files. They tell the system that there are no media files in this folder to display in the gallery. Removing them will result in system icons and application logos appearing in the gallery, which will clog the visuals.
