Modern smartphones of the series Samsung Galaxy have powerful hardware, but even they begin to work slower over time due to the accumulation of temporary files. Messenger Viber is one of the most popular communication applications that uploads gigabytes of photos, videos and voice messages every day. All this content is stored in a special storage - a cache, which is necessary for quickly loading media files when chats are reopened.
However, over time, the size of this storage can reach tens of gigabytes, which critically affects the free space in the device’s internal memory. If your Samsung Galaxy started to issue notifications about low memory or the messenger itself began to slow down when scrolling through the history, then it’s time for maintenance. Clearing the cache is a safe procedure that will not delete your personal correspondence or contacts, but will return the system to performance.
In this article we will look in detail at all the ways to delete temporary files on devices running the shell One UI. You'll learn how to clean through the system settings, use the built-in tools of the application itself, and use third-party utilities for a deeper cleaning of the system. Follow the instructions carefully so as not to delete important data by mistake.
Why the Viber cache grows and affects the speed
The principle of operation of any messenger, including Viberimplies local storage of data to optimize traffic. When you open a photo in a chat, it is downloaded once and stored in the cache. The next time you open the same image, the application takes it from the internal memory, rather than downloading it again from the network. This speeds up the work, but leads to a constant increase in the occupied volume.
On smartphones Samsung Galaxy with a small amount of built-in memory (for example, 32 or 64 GB), cache overflow can be fatal. The Android system becomes unstable because it does not have enough space to create temporary files for other processes. As a result, you may experience interface freezes, long application launch times, and even spontaneous device reboots.
⚠️ Attention: Do not confuse clearing the cache with resetting application data. If you select the “Erase data” or “Clear storage” option, you will irrevocably lose all correspondence history and account settings within the application. Regular cleaning of temporary files helps maintain your smartphone at a high level. This is especially true for users who actively participate in group chats, where media files are exchanged every minute. Ignoring this procedure may result in the messenger simply stopping downloading new messages due to lack of free space.
Regularly cleaning temporary files helps maintain performance smartphone at a high level. This is especially true for users who actively participate in group chats, where media files are exchanged every minute. Ignoring this procedure may result in the messenger simply stopping downloading new messages due to lack of free space.
Set up automatic deletion of media files in Viber itself so that the cache does not grow to critical sizes in the future.
Preparing your smartphone for the procedure cleaning
Before you start deleting files, you need to make sure that the device is ready to manipulate system settings. Although clearing the cache is a safe operation, it is recommended to close all applications running in the background to avoid process conflicts during cleaning. This is especially important for owners of older models of the line Galaxy A or Galaxy M.
It is also worth checking the current amount of occupied memory to understand the scale of the problem. You can go to the settings menu and view storage usage statistics. This will give you an idea of how much space is actually freed up after the procedure and how much it was needed for your specific model.
- 📱 Close all active applications through the multitasking menu.
- 🔋 Make sure the battery charge is at least 20% so that the phone does not turn off in the process.
- 💾 Free up some space manually if the memory is full (delete unnecessary downloaded files).
- 🔄 Reboot the device before starting work to reset temporary system errors.
If you use a memory card microSD to store Viber media files, make sure that it is correctly mounted by the system. Sometimes card reading errors can prevent the cache from clearing normally or cause the application to crash after clearing. In such cases, it is better to temporarily transfer important files to your computer.
Clearing the cache through the Android system settings
The most reliable and correct way to delete temporary files on Samsung Galaxy is using the built-in application manager. This method is guaranteed to clear the cache without affecting your personal data and message database. The shell interface One UI may differ slightly on different versions of Android, but the logic of actions remains the same.
First, you need to open the main phone settings menu. Find the section responsible for managing installed apps. In modern firmware versions this item is usually called "Applications". This displays a complete list of all software installed on your device, including system services and user apps.
Settings → Applications → Viber → Storage → Clear cacheAfter entering the application menu, you will see detailed statistics on memory usage. Two main parameters will be indicated here: the size of the application itself and the size of the data (cache). Clicking the clean button will only delete temporary files, freeing up space for new messages and media files. The process takes only a few seconds.
| Action | What is deleted | Risk of data loss | Recommended frequency |
|---|---|---|---|
| Clear cache | Temporary files, thumbnails | No | Once a month |
| Data clearing | All history, settings, account | High | Only when resetting |
| Deleting the application | The app and all files | Complete loss | When uninstalling |
| Deleting media | Photos and videos from the gallery | Medium | As needed |
Use only the "Clear Cache" button to keep your chat history and account settings intact.
Please note that after clearing the cache on first launch Viber it may work a little slower than usual. This is normal, as the application needs to regenerate the image thumbnails and load data from the network. After a few minutes of operation, the speed will be restored, but now you will have several gigabytes of free space.
Using the built-in Device Care tool
The Company Samsung equips its smartphones with a useful utility Device Care (or "Device Maintenance" in Russian localization). This tool automatically analyzes the system status and suggests optimizing your phone, including cleaning up unnecessary files. This is a simpler method that does not require a deep dive into the settings of each application separately.
Launch the "Settings" application and find the "Device Maintenance" item. The system will conduct a quick analysis and show the current status of memory, battery and security. If the messenger cache takes up a lot of space, a smart algorithm will suggest deleting unused files and temporary application data with one click.
- 🧹 Click the "Clean Now" button to remove system junk.
- 📂 Go to the "Memory" section for a more detailed analysis.
- 🗑️ Select "Untitled files" or "Large files" for manual sorting.
- ⚙️ Set up auto-cleaning in the advanced maintenance settings menu.
The advantage of using Device Care is that it deletes the cache not only of Viber, but also of other applications that accumulate garbage. This is a comprehensive approach to optimization Samsung Galaxythat helps keep the system clean at a constant level without the need for manual intervention in each application.
⚠️ Warning: The Auto Clean feature in Device Care may remove files from your downloads folder that you have downloaded, but not opened. Check the list of files before confirming deletion.
☑️ Check before cleaning via Device Care
Clearing history and media files inside the Viber application
In addition to the system cache, the messenger itself Viber has its own data storage settings. Inside the application, you can delete call history, specific messages with heavy attachments, or set up automatic deletion of media files. This method allows you to precisely control what exactly takes up space on your Samsung Galaxy.
Go to the settings of the messenger itself by clicking on the “More” icon in the lower right corner. Select the "Memory and Data" section. Here you will see detailed statistics on space usage: how much photos, videos, voice messages and documents take up. You can clear any of these types of files separately without deleting text correspondence.
The "Clear cache" function inside the application works similarly to the system one, but is sometimes more effective for specific messenger files. There is also an option to disable autosaving of photos and videos to the phone gallery. Disabling this function will prevent duplication of files: they will be stored only inside the chat, without clogging the main gallery. Android.
How to delete a specific chat completely?
Press your finger on the desired dialogue in the list of chats, select the trash can icon and confirm deletion. This will delete all correspondence and media files of this contact permanently.
Regularly viewing the "Memory Usage" section inside Viber helps control the growth of the database. If you see your data volume growing too quickly, you may want to reconsider activity in large groups or ask members not to send heavy videos unnecessarily. This will extend the life of your smartphone's memory.
Problems after cleaning and ways to solve them
In rare cases, after clearing the cache, users encounter incorrect operation of the application. Contact avatars may disappear, picture previews may not load, or errors may occur when sending messages. Typically, these are temporary phenomena due to the fact that the application needs time to re-index files and download data from the server.
If the problems do not disappear within an hour, try force stopping the application and starting it again. To do this, go to your phone settings, find Viber and click the "Stop" button. After that, open the messenger as usual. In most cases, this solves problems with displaying content.
In more complex situations, when the application constantly crashes or does not connect to the network, a complete reinstallation may be required. Before doing this, be sure to create a backup copy of your correspondence so as not to lose important data. Delete the application, restart your phone and download the latest version from the official store Google Play or Galaxy Store.
⚠️ Attention: The settings interface may change with One UI firmware updates. If you do not find an item, use the search in the phone settings by the name of the function.
If after clearing the cache the phone still slows down, check for Android system updates - sometimes memory problems are solved by security patches.
Prevention of memory clogging on Samsung Galaxy
So as not to return to the issue of cleaning cache every week, it's worth introducing a few smartphone habits. First, go through your downloads folder regularly and remove unnecessary files. Secondly, use cloud storage to back up photos and videos, freeing up local space.
Configure media file upload settings in Viber. You can set a limit to automatically download photos and videos only when connected to Wi-Fi. This will not only save mobile traffic, but also prevent the cache from instantly filling with heavy files while you are away from home.
- ☁️ Enable synchronization with Google Photos or Samsung Cloud.
- 📵 Disable autosaving of media to the gallery in the messenger settings.
- 🗑️ Once a month, review group chats and leave inactive ones.
- 📲 Use the "Archive" function for old dialogues instead of deleting them.
Following these simple rules will allow your Samsung Galaxy work quickly and stably throughout the entire period services. Memory is one of the most important resources of a modern smartphone, and careful treatment of it guarantees the absence of lags and freezes at the most inopportune moment.
Will my correspondence be deleted when clearing the cache?
No, clearing the cache deletes only temporary ones files (thumbnails, uploaded images for quick access). The entire text correspondence history, contacts and settings will remain intact. You will lose access to photos only until you open the chat again and they are downloaded from the network.
Why does the cache grow quickly again after clearing?
The cache is the working area of the application. As soon as you start actively using Viber, viewing photos and listening to voicemails, the cache begins to fill up again. This is normal app behavior to ensure performance. Growth depends on the intensity of your communication.
Is it possible to transfer Viber to a memory card on Samsung?
On modern versions of Android and the One UI shell, transferring full-fledged applications to a memory card is often unavailable or does not work correctly. System files and the messenger database must remain in the internal memory for stable operation. You can only transfer media files to the card through the settings of the application itself.
How to learn how much space Viber takes up?
Go to Settings → Applications → Viber. The application information screen will show two values: the size of the application itself (app code) and the size of the data (your communications and cache). The sum of these values shows the total space occupied by the messenger.
Is it safe to use third-party cleaning apps?
Using popular utilities like CCleaner or the built-in Clean Master is acceptable, but often redundant. Built-in Android and Samsung Device Care tools do the job more efficiently and securely. Third-party applications can impose advertising or delete necessary files by mistake.
