Smartphone Samsung Galaxy S7, released several years ago, still remains a reliable device for many users. However, over time, the accumulation of temporary files can lead to a noticeable decrease in performance, slowdown of the interface and rapid drainage of the battery. Understanding how to clear the cache on Android Samsung 7is a key skill for extending the life cycle of this gadget without the need to replace it.
Cache memory is designed to speed up applications by storing frequently used data, but its excess volume begins to work against the user. In this article, we will analyze in detail all available cleaning methods: from deleting temporary files of individual apps to completely wiping the system partition through recovery mode. You will learn which actions are safe and which require special care so as not to lose important data.
What is the cache and why delete it on the Galaxy S7
The cache is a memory area where Android installed applications store temporary data for quick access. When you open a browser or social network, the device downloads images and scripts, storing them locally so that the page opens instantly the next time you visit. Over time, these files take up gigabytes of space, especially on models with a small amount of internal memory.
Regular cache clearing is necessary when you notice that your phone is starting to run slower than usual. Sometimes temporary files become damaged, which leads to app errors or sudden closures. Deleting this data forces the system to re-download the latest versions of files, which often solves problems with software stability.
It is important to distinguish between the application cache and the system cache. The first one can be deleted selectively for specific apps that take up too much space. The second is temporary files of the operating system itself TouchWiz or newer shells that accumulate after firmware updates or device failures.
⚠️ Attention: Clearing the cache does not delete your personal photos, contacts or messages. However, clearing application data (not to be confused with the cache) will lead to a complete reset of the app to factory settings and loss of information stored inside it.
Clearing the cache of individual applications through the settings
The safest and most common way to free up space is to manage the memory of specific apps through the standard settings menu. This method allows you to specifically remove garbage from heavy applications, such as Instagram, YouTube or browsers that tend to accumulate huge amounts of temporary data.
First, you need to go to the main menu of the device and find the settings section. The interface may differ slightly depending on the version Android, but the logic remains the same. You need to find a list of all installed apps and select the one that raises suspicions about resource consumption.
After selecting an application, a screen with detailed information about it will open. Here you will see two important buttons: “Clear cache” and “Clear data”. The first one deletes only temporary files, the second one resets the application completely. Use the first option for regular maintenance.
Pay attention to the cache size in the application menu. If it takes up more than 500 MB, cleaning will give a noticeable visual effect and free up a significant amount of internal memory.
Repeat this procedure for all resource-intensive apps once a month. This will help keep the system in good shape without the need to use third-party software. This works especially effectively for messengers that save a lot of media files in temporary storage.
☑️ Step-by-step cleaning of the application
Using the built-in Samsung optimizer
The company Samsung has implemented a powerful built-in optimizer in its devices a system maintenance tool that is accessible directly from the notification shade or settings menu. This utility automatically analyzes the state of the device and offers to delete unnecessary files, including the cache, in one click.
To use this feature, lower the top notification shade and look for the gear icon or the “Optimize” button. The system will scan and show how much space can be freed. This is the easiest way for users who do not want to understand the technical details.
The built-in optimizer also checks background processes and closes applications that consume battery power in the background. Regular use of this tool, at least once a week, helps prevent the accumulation of a critical mass of temporary files.
| Type of cleaning | What is deleted | Security | Recommended frequency |
|---|---|---|---|
| Application cache | Temporary files apps | Completely safe | Weekly |
| Application data | Settings and logins | Requires caution | Only when failures |
| System cache | OS update files | Safe in Recovery | After updates |
| Optimizer | Background processes and garbage | Safe | Daily |
Despite the convenience of automatic tools, manual storage checks sometimes give better results. Automation may miss some large cache files, which the user can identify and delete independently through the file manager or storage settings.
Clearing the system cache through Recovery mode
There is a deeper level of cleaning available through a special recovery menu - Recovery Mode. This method allows you to delete the partition cache partitionwhere system temporary files are stored without affecting the user's personal data. This is especially useful after major firmware updates.
To enter this mode, you must completely turn off the smartphone Galaxy S7. Then you need to hold down a key combination: usually this is the volume up button, the Home button and the power button at the same time. Hold them until the logo appears Samsung, then release the power button while continuing to hold the other two.
In the menu that appears, navigation is carried out using the volume buttons, and the choice is confirmed with the power button. You need to find the item Wipe Cache Partition. Be extremely careful: do not confuse this item with Wipe Data/Factory Reset, which will delete all your data permanently.
⚠️ Attention: In Recovery mode, the touch screen does not work. Use only the physical volume buttons to navigate through the menu and the power button to confirm the selection.
After confirming the selection, the system will warn you to confirm the action. Select Yes and wait for the process to complete. When finished, select Reboot System Now to reboot the device in normal mode.
What to do if the Recovery menu does not appear?
If the standard button combination does not work, try connecting the phone with a USB cable to the computer before turning it on. On some firmware versions, this is a prerequisite for entering recovery mode.
Third-party applications for clearing memory
There are dozens of utilities on the market that promise to speed up the phone, but not all of them are useful for Samsung Galaxy S7. Many of these apps themselves consume resources and display intrusive ads, negating the benefits of cleaning.
However, proven solutions from well-known developers can be useful for in-depth storage analysis. They allow you to find duplicate files, remnants of deleted applications and hidden cache folders that are difficult to detect manually.
When choosing such software, give preference to tools that have a transparent privacy policy and do not require unnecessary permissions. Avoid apps that promise “CPU cooling” or “Internet speedup,” as these functions are often a marketing ploy.
- 🧹 Clean Master - a popular solution with the function of clearing the cache and speeding up games, but requires careful configuration of notifications.
- 🛡️ CCleaner - a reliable tool with real-time system monitoring and safe garbage removal.
- 📂 Files by Google — Google's official file management app with a built-in junk cleaning feature.
Remember that third-party apps cannot clear the system cache partition as effectively as Recovery mode. Their main task is to work with user space and the cache of installed apps.
Third-party cleaners are useful for finding forgotten files, but built-in Android tools often cope with basic cache clearing just as well and without the risk of installing unnecessary software.
Prevention and maintenance recommendations
To ensure that your Galaxy S7 works quickly for as long as possible, It is important not only to clear the cache, but also to follow certain operating rules. Regular maintenance prevents critical memory filling, which is the main cause of brakes.
Try not to fill the internal memory of the device to capacity. Leave 10-15% of free space for normal system operation and the creation of temporary files. If the memory is full, the operating system becomes unstable.
Periodically check the list of installed applications and remove those that you do not use. Even when inactive, apps can take up space and run in the background. Disabling or deleting unnecessary software is the best prevention of cache clogging.
⚠️ Attention: Interfaces and menu item names may vary slightly depending on the Android version and regional firmware. If you do not find the specified item, check the “Device Manager” or “Device Maintenance” section.
Use a memory card microSD to store photos, music and videos. Transferring media files to external media frees up internal memory for system operation and application caching, which has a positive effect on the interface response speed.
Periodic rebooting of the smartphone (every 3-4 days) helps to automatically reset some of the system caches and terminate hung background processes without user intervention.
Frequently asked questions (FAQ)
Will clearing the cache delete my photos and contacts?
No, clearing the cache only affects temporary files that speed up applications. Your personal data such as photos, contacts, messages and notes will remain completely safe. Delete only the cache, not application data.
How often should you clear the system cache via Recovery?
It is enough to do this once every few months or after a major system update. Frequently clearing the system cache does not make sense, since the system will create it again during operation, which can even temporarily slow down the phone.
Why did the phone begin to work slower after clearing the cache?
This is normal in the first minutes after cleaning. Applications take time to re-create the necessary temporary files and load data. The operating speed will be restored after actively using apps for a short time.
Is it possible to delete the Android folder completely?
No, you cannot delete the entire folder Android as important application data is stored in it. You can clear the contents of a subfolder cache inside it, but deleting the entire directory will cause the installed software to malfunction.
Does clearing the cache affect the battery charge?
Indirectly, yes. If the cache is corrupted, applications may not run correctly and consume more CPU resources, which can drain them faster. Clearing the cache restores the normal operation of apps, which can have a positive effect on autonomy.
