Smartphones series Samsung Galaxy A, including the popular A50 model, inevitably slow down over time due to the accumulation of temporary files and logs. The operating system Android in conjunction with the shell One UI creates a lot of service data that is not deleted automatically. Many users mistakenly believe that installing third-party “cleaners” will solve the problem, but built-in tools are often more effective and safer.
In this guide, we will look at how to free up gigabytes of internal memory using only the standard capabilities of the device. You will learn how to find hidden folders, clear the cache of specific applications, and remove remnants of deleted software. This will allow you to return the interface to its former speed and free up space for new photos or games without losing personal data.
Diagnostics of occupancy and memory analysis
Before starting active actions, you need to understand what exactly is taking up space. Unlike older versions of Android, modern ones hide some system folders from the eyes of the average user. To get started, open the standard “My Files” application and go to the “Storage Analysis” section. Here you will see a visual diagram of data distribution. file managers hide some system folders from the eyes of the average user. To get started, open the standard “My Files” application and go to the “Storage Analysis” section. Here you will see a visual distribution chart of the data.
Pay attention to the “Other” or “System Data” category. Often this is where update logs, temporary download files and remnants from deleted games accumulate. If this partition takes up more than 10-15 GB, manual cleaning is required. Do not rush to delete the first files you come across, as this may disrupt the operation of system services.
It is important to distinguish between memory types. The application cache is temporary data to speed up loading and can be deleted without consequences. Application data is your settings, saves in games and correspondence, the deletion of which will reset the app to its original state. Be extremely careful when choosing the type of cleaning in the settings menu.
⚠️ Attention: Do not delete files from foldersAndroid/obbandAndroid/datamanually through third-party explorers without understanding their purpose, as this may cause games and applications to crash.
Before the mass By cleaning, back up important documents to cloud storage Samsung Cloud or Google Drive to eliminate the risk of accidental data loss.
Clearing the cache of system applications and services
The most effective way to free up space is to specifically clear the cache of heavy applications. Owners Samsung A50 often encounter an increase in the cache of social networks and instant messengers. Go to Settings → Applications and sort the list by memory size.
Select the leading application, for example YouTube, Telegram or Instagram. Inside the application menu, find the “Storage” item. Here you will see two buttons: “Clear cache” and “Clear data”. Click only on the first button if you want to save your accounts and settings. The second button will completely reset the application.
The “Gallery” system application deserves special attention. After viewing thousands of photos and videos, thumbnails can take up hundreds of megabytes. Clearing the gallery cache will force the system to re-index media files, which will temporarily increase the CPU load, but will free up valuable space.
- 📱 Clear your browser cache (Chrome, Samsung Internet) weekly, as they save copies of all pages visited.
- 🗑️ For instant messengers, use built-in cleaning of download history, and not just the system cache.
- ⚙️ Do not forget about the Weather and News applications, which cache a lot of graphic content.
Repeat this procedure for the top 5 largest applications. This will give instant results in the form of several gigabytes of free memory. Automatic clearing in phone settings often misses some hidden caches, so the manual method remains the most reliable.
☑️ Check application cache
Manually deleting temporary files and logs
For deeper cleaning, you will need to go to the root directory of the internal memory through Explorer. In One UI this is done through the “My Files” → “Internal Memory” application. Here are folders that are not visible in the standard analyzer.
Find a folder named Download or “Downloads”. Users often forget about downloaded installation files APK, presentations or archives that are no longer needed. Feel free to delete all the contents of this folder, having first checked whether there are any important documents there.
It is also worth paying attention to the folder DCIM. Inside it there may be a subfolder .thumbnails (hidden), which stores thumbnails of deleted photos. To see hidden folders, click on the three dots in the Explorer menu and turn on the “Show hidden files” option. Deleting the contents of this folder is safe, the system will create it again if necessary.
Folders for manual checking:/Download
/DCIM/.thumbnails
/Android/data (only empty folders from deleted games)
/Bluetooth
Another place where “garbage” accumulates is the folder Bluetooth. If you've ever received files via Bluetooth, they lie there like dead weight. Check its contents and delete old images or audio files transferred from other devices.
⚠️ Attention: The interface One UI is periodically updated, and the names of some system folders may change. If you are not sure about the purpose of the folder, it is better to look for information about it in the official Samsung knowledge base.
Optimizing the operation of instant messengers and social networks
Messengers are the main “eaters” of memory on modern smartphones. Telegram and Viber by default, they save all received media files to the internal memory. Without configuration, these applications can quietly take up 5-10 GB per month of active use.
In Settings Telegram go to the “Data and Memory” → “Memory Usage” section. Here you can set a cache size limit or configure automatic cleaning of media files that have not been opened for more than a week. This is a critical setting for owners Samsung A50 with a limited amount of built-in storage.
In WhatsApp the situation is similar. Go to Settings → Data and Storage → Manage Storage. The app will show you the chats that take up the most space and offer you the option to selectively delete large video files. This allows you to clear the memory without losing the text history of correspondence.
| Application | Path to clearing | Recommended frequency |
|---|---|---|
| Telegram | Settings → Data and memory | Once every month |
| Settings → Storage management | Once every 2 weeks | |
| Viber | More → Settings → Storage | Once a month |
| Phone settings → Applications | When the brakes |
Do not ignore the settings for auto-loading media on mobile networks. By disabling this feature, you will not only save space, but also save traffic. Files will be downloaded only when the chat is opened and there is a Wi-Fi connection.
Setting up auto-clearing the cache in instant messengers is more effective than manually deleting files, as it prevents the re-accumulation of garbage.
Removing remnants of deleted applications and games
When deleting games through a standard application manager, heavy files are often left behind graphics and sound. This data is located in system directories and is not deleted automatically. To find them, use the “My Files” explorer again.
Navigate to the path Android/obb. Game cache files are stored here. If you see folders with the names of deleted games (usually a series of numbers or the name of the developer), they can be safely deleted. Deleting active game folders will result in the need to re-download the data at startup.
A similar situation with the folder Android/data. Applications store their working data inside it. Check the folder names: if the application has already been deleted from the phone, the corresponding folder here is garbage. However, be careful: deleting folders of installed apps will reset their settings.
- 🎮 Folders in
Android/obbcan weigh from 500 MB to 2 GB each. - 📂 Remains from cards (Google Maps, 2GIS) often contain offline city maps.
- 🧹 Use a search for the word "cache" in Explorer to find hidden temporary folders.
If you are not sure whether a folder belongs to a remote application, try to remember if you have recently played projects from this developer. If in doubt, it is better to leave the folder than to risk the functionality of the software.
What to do if the folder is not deleted?
If the system writes “File busy” or “No access”, try rebooting the phone into safe mode. To do this, hold down the power button, and then hold your finger on the “Shut down” icon on the screen for a long time until you are prompted to boot into safe mode. In this mode, third-party applications do not work and do not block files.
Using the built-in Samsung optimizer
The shell One UI has a powerful device maintenance tool preinstalled, which is often underestimated. It is in the menu Settings → Device Maintenance. This comprehensive tool analyzes the health of the battery, memory and security.
Click the “Optimize Now” button. The system will automatically close background processes that consume a lot of RAM and offer to delete unnecessary files. In the “Memory” section, you can click “Clean up now” to delete temporary files that the system considers safe to delete.
Also in this menu there is an “Auto-optimization” function. It is recommended to configure it to start at night when the phone is not in use. This will ensure continuous performance support at a high level without your participation. The algorithms Samsung are smart enough not to delete important data.
You should not rely only on automatic cleaning, as it is often superficial. The combination of the built-in optimizer and manual cleaning described above gives the best result for the model Galaxy A50.
⚠️ Attention: Avoid installing dubious memory cleaning applications from the Play Market. They often contain ads, run in the background, and slow down your phone even more than the junk they claim to remove.
Frequently asked questions (FAQ)
Is it safe to delete the Android folder completely?
No, delete the entire folder Android absolutely not. This will break all installed applications. You can only delete specific subfolders inside data and obbthat correspond to already deleted apps.
Why does space quickly run out again after cleaning?
Most likely, you do not have auto-cleaning configured in messengers or have full photo synchronization enabled permission. Check your cache settings in Telegram i WhatsApp, and also disable uploading photos to the gallery if you are using the cloud.
How to clear the cache without losing data in games?
Use the path Settings → Applications → [Game] → Storage → Clear cache. Never click "Clear data" if you want to save your progress. To be safe, link the game to your Google Play Games or Facebook account.
Is it possible to transfer garbage to a memory card before deleting?
Technically it is possible, but inappropriate. Junk files are of no value. Transfer only personal photos, videos and documents to the memory card, and simply delete temporary files and cache.
Does cleaning garbage affect the charging speed?
Directly - no. However, if the phone is not overheating due to background processes that often accompany a clogged system, charging efficiency may be more stable. The main benefit of cleaning is the speed of the interface.
