Has your tablet begun to slow down, applications take a long time to load, and there is less than 1 GB of free memory left? Most likely, the problem lies in a full cache. Cached data are temporary files that applications and the system create to speed up work. But over time, they accumulate and begin to interfere: they take up storage space, slow down performance, and can even cause apps to crash. Samsung Galaxy Tab started to slow down, applications take a long time to load, and there is less than 1 GB of free memory left? Most likely, the problem lies in a full cache. Cached data are temporary files that applications and the system create to speed up work. But over time, they accumulate and begin to interfere: they take up storage space, slow down performance, and can even cause apps to crash.

In this article you will find 5 proven ways to clear the cache on tablets Samsung —from standard Android tools to hidden functions One UI. We will look at how to clear the cache of individual applications, the system cache, and also what to do if the tablet does not respond to commands. All instructions are relevant for models Galaxy Tab S8/S7/S6, Tab A, Tab Active and other lines based on Android 10–14.

1. Clearing the cache of individual applications

If a specific application is slow (for example, YouTube, Chrome or Facebook), just clear its cache - this will not delete your data (logins, saves, bookmarks), but will free up space and speed up the app.

How to do it do:

  • 📱 Open Settings → Applications
  • 🔍 In the search bar, enter the name of the problematic application (or scroll the list)
  • 🗑️ Click Memory → Clear cache
  • 🔄 If necessary, also click Clear data (⚠️ this will delete all application settings!)

For convenience, you can sort applications by cache size: in the menu Applications click on the three dots in the upper right corner and select Sort by size. This way you will quickly find the most "gluttonous" apps.

⚠️ Attention: Do not clear the cache of system applications (for example Android System WebView or Google Play Services) unless necessary. This may cause the tablet to malfunction.

2. Automatic cache clearing via Device Care

Tablets Samsung have a built-in tool Device Care (previously - Optimization), which analyzes the state of the device and offers to optimize its operation. The function automatically finds unnecessary cached files and offers to delete them.

Instructions:

  1. Go to Settings → Device Maintenance (or Device Care)
  2. Click Memory (or Storage)
  3. Wait for analysis to complete (usually takes 10-30 seconds)
  4. Click Clear now (or Optimize)

In the same menu you can enable automatic cleaning: activate the switch Auto-optimization. The tablet will automatically delete unnecessary files once a day (by default - every 3:00 am).

💡

If the function Device Care does not find the cache to clear, try rebooting the tablet - sometimes the system does not see temporary files without a reboot.

3. Clearing the system cache via Recovery Mode

If the tablet is very slow or does not respond to commands, you may need to clear system cache (the so-called cache partition). This procedure does not delete your data, but resets temporary Android files that may have been damaged.

⚠️ Important: Do not confuse Wipe Cache Partition with Factory Reset —the second option will completely reset the tablet to factory settings!

How to log in Recovery Mode and clear the cache:

  1. Turn off the tablet.
  2. Press the buttons simultaneously Power + Volume up (on some models - Power + Volume up + Home).
  3. When the logo appears Samsungrelease the buttons - after 5-10 seconds the menu will open Recovery.
  4. Use the volume buttons to navigate and select Wipe Cache Partition.
  5. Confirm the action with the button Power.
  6. After completion, select Reboot System Now.

The process may take 2-5 minutes. After rebooting, the tablet will work faster, and some system errors will disappear.

What to do if you cannot enter Recovery?

If the combination buttons do not work, check:

1. The tablet is completely turned off (not in sleep mode).

2. You are using the correct combination for your model (new ones Galaxy Tab S may need to be connected to charging).

3. press one by one).

If nothing helps, try using ADB commands from a PC: adb reboot recovery

4. Using third-party applications for cleaning

If built-in tools Samsung cannot cope, you can use specialized utilities. They offer advanced functions: cleaning residual files, analyzing junk data, and even optimizing startup.

Top 3 proven applications for clearing the cache:

  • 🧹 CCleaner - deletes cache, temporary files and remnants of deleted apps. There is a cleaning function Dalvik-cache (for experienced users).
  • 🚀 SD Maid - finds "dead" files, duplicates and system application cache. Suitable for deep cleaning.
  • 🔍 Files by Google - a simple tool from Google with a function Cleaningthat deletes unnecessary files and cache.

⚠️ Warning: Some "cleaners" (especially from unknown sources) may contain adware or collect data. Install applications only from Google Play and check reviews.

5. Clearing the cache Google Play Services and other system components

Some system applications (for example, Google Play Services, Samsung Push Service) actively use the cache, but clearing them can solve problems with updates, notifications and Google account operation. data-i="154">How to clear the cache of hidden system applications:

How to clear the cache of hidden system applications:

  1. Open Settings → Applications.
  2. Click on the three dots in the upper right corner and select Show system applications processes.

    ⚠️ Attention: Do not clear data (Clear Data) from Google Play Services —this will cause all Google services on the device to fail. Just the cache is enough.

    6. When clearing the cache does not help: alternative solutions

    If after clearing the cache the tablet still slows down, the problem may lie deeper. Let's consider alternative optimization methods:

    • 🔄 Rebooting the tablet — sometimes it is enough to turn off and turn on the device so that the system cleans itself of temporary files.
    • 🗃️ Transferring data to an SD card —if memory is critically low, move photos, videos and documents to an external drive.
    • 🧹 Reset to factory settings is a last resort if other methods have not helped. Attention: this will delete all data from the tablet!
    • 🔧 Firmware update —an outdated version of Android may cause lags. Check for updates in Settings → Software update.

    If the tablet Samsung began to slow down after updating the firmware, try rolling back the changes via Smart Switch (official utility from Samsung) or wait for the next patch - bugs are often fixed in new versions.

    💡

    If free memory is less than 10% of the total volume, Android starts working in emergency mode, which leads to a sharp drop in performance. Regularly clearing the cache helps avoid this.

    FAQ: Frequently asked questions about clearing the cache on Samsung

    ❓ Do you need to clear the cache regularly?

    No, not necessarily. Android manages the cache itself and in most cases no intervention is required. Clear the cache only if:

    • The tablet has become noticeably slower.
    • Applications crash or work incorrectly.
    • The space on the internal storage has run out.

    Frequent cleaning can, on the contrary, slow down the work, as applications will have to re-create the cache.

    ❓ What will happen if you clear the cache WhatsApp or Telegram?

    Clearing the messenger cache will delete:

    • Downloaded media files (photos, videos, voice messages).
    • Temporary files (for example, video previews).

    ✅ Will not be deleted: correspondence, contacts, account settings. The next time you open the application, the files will start downloading again (if they are still available on the server).

    ❓ Why do applications take a long time to load after clearing the cache?

    This is normal! The cache is needed just to speed up loading. After cleaning, applications have to:

    1. Re-download temporary data (for example, thumbnails in Instagram).
    2. Compile files for optimal performance (this applies to games).

    After 1-2 uses the application will work quickly again.

    ❓ Is it possible to clear the cache for everyone applications immediately?

    Yes, but not through standard settings. Options:

    • Use Device Care (section Memory → Clear).
    • Install third-party application (for example, SD Maid).
    • Manually clear the cache via ADB (for advanced users):
    adb shell pm list packages -f | sed 's/.*=//' | xargs -n1 adb shell pm clear

    ⚠️ The last method will delete all data applications (not only the cache), so use it carefully!

    ❓ Why there is no menu on the tablet Device Care?

    Possible reasons:

    • You have an old model Samsung (until 2017), where this function was called Optimization or Smart Manager.
    • The firmware has been modified (for example, custom firmware has been installed).
    • The function has been disabled by the device administrator (on corporate tablets).
