What cache is and why clearing it helps

Cache is temporary data that apps and your web browser store on your tablet to load faster next time. When you watch a video, open an email, or browse a website, your tablet saves pieces of that content locally so it doesn't have to read everything again. Over time, this cache builds up and can slow your tablet down, cause apps to behave oddly, or use storage space you need for other things.

Clearing cache does not delete your passwords, photos, or any files you created. It only removes the temporary copies apps made while running. Think of it like emptying a junk drawer—you're throwing out scraps, not your important documents.

Key Takeaways

  • Cache lives in two places on your Samsung tablet: inside individual apps and in your web browser, and you can clear each separately.
  • The fastest way to clear all app cache at once is through Settings > Apps, then selecting each app and tapping "Clear cache"—this takes a few minutes but covers everything.
  • Clearing your browser cache (in Chrome, Samsung Internet, or Firefox) removes saved website data and is separate from clearing app cache.
  • You can also clear cache automatically by going to Settings > Apps > [app name] > Storage and toggling on auto-clear, though this is not available for all apps.
  • Clearing cache is safe and will not remove your login information, photos, or documents—only temporary files apps created while running.

Clear cache for all apps at once through Settings

The quickest way to clear cache from every app on your tablet is through the Settings menu. Open Settings, then tap Apps. You will see a list of all installed apps. At the top right, tap the three-dot menu (or look for More options), then select Clear cache. Your tablet will remove cached data from all apps in one action.

This method works on most Samsung tablets running Android 10 and newer. If you do not see a "Clear cache" option in the three-dot menu, your tablet may be running an older version of Android, and you will need to clear cache app by app instead (see the next section).

Clear cache for individual apps

If you want to clear cache only for specific apps—say, your email or a game that is running slowly—you can do it one at a time. Open Settings, then Apps. Find the app you want to clear, tap it, then tap Storage. You will see two buttons: Clear cache and Clear data. Tap Clear cache only. (Do not tap "Clear data" unless you want to reset the app completely, which will log you out and erase your settings.)

Repeat this for any other apps you want to clear. This method takes longer than clearing all cache at once, but it gives you control over which apps you affect. It is useful if one app is misbehaving and you want to leave others alone.

Clear cache in your web browser

If you use Chrome as your browser, open the app and tap the three-dot menu in the top right corner. Select Settings, then Privacy and security, then Clear browsing data. Make sure Cached images and files is checked, then tap Clear data. You can also choose a time range (last hour, last day, all time) before clearing.

If you use Samsung Internet (the browser that comes built into Samsung tablets), open the app and tap the three-line menu at the bottom right. Go to Settings, then Privacy, then Delete browsing data. Check Cached data and tap Delete. If you use Firefox, open the app, tap the three-line menu, select Settings, then Delete browsing data, and make sure Cache is checked before tapping Delete browsing data.

Set apps to clear cache automatically

Some Samsung tablets allow you to turn on automatic cache clearing for individual apps. Open Settings, then Apps, then select an app. Tap Storage, and if the option appears, toggle on Auto clear cache. This will clear that app's cache every time you close it, so you do not have to do it manually.

Not all apps support this feature, and it is not available as a system-wide setting on all Samsung models. If you do not see the toggle, the app does not support automatic clearing, and you will need to clear its cache manually when needed.

What to do if your tablet is still slow after clearing cache

If clearing cache does not speed up your tablet, the slowness may come from something else. Check how much storage space you have left by going to Settings > Storage. If you are using more than 90 percent of your storage, your tablet will slow down even with cache cleared. Delete old photos, videos, or apps you no longer use to free up space.

You can also restart your tablet, which clears temporary memory and often fixes lag. Hold the power button until the power menu appears, then tap Restart. If slowness continues after clearing cache, restarting, and freeing up storage, a hardware issue or a problematic app may be the cause, and you may want to contact Samsung support or visit a repair shop.

Frequently Asked Questions

Will clearing cache delete my passwords or login information?

No. Cache is only temporary files apps created while running. Your passwords are stored separately in your tablet's find storage and are not affected by clearing cache. You will stay logged into apps and websites after clearing cache.

Can I clear cache without going into Settings?

On some Samsung tablets, you can use the Device Care app (if installed) to clear cache quickly. Open Device Care, tap Storage, then Optimize. This clears cache and temporary files in one tap. If you do not have Device Care, the Settings method is the standard way.

How often should I clear cache?

There is no set schedule. Clear cache when your tablet feels slow, when an app is misbehaving, or when you are running low on storage space. If you use your tablet heavily every day, clearing cache once a month is reasonable. If you use it lightly, clearing it every few months is fine.

Is clearing cache the same as clearing data?

No. Clearing cache removes temporary files only. Clearing data resets the app completely—you will lose your login, settings, and saved preferences. Always tap "Clear cache" unless you want to fully reset an app.

What if I clear cache and an app stops working?

Clearing cache will not break an app. If an app stops working after clearing cache, restart your tablet. If the problem continues, uninstall and reinstall the app from the Google Play Store. This is rare and usually means the app had a separate problem, not that clearing cache caused it.
