How To Clear Cache On Samsung S21

What is Cache and Why Should You Clear it?

Cache is temporary data stored by apps and the Android operating system. It contains files that apps may need again in the future to load faster. However, over time cache can build up and contain outdated or corrupted files that slow down your device. Clearing it out periodically can speed up performance and fix app issues.

Here are some of the benefits of wiping cache on your S21:

  • Speed up overall system performance
  • Fix app crashes, freezing, or force closes
  • Resolve launcher issues like home screen lag
  • Improve slow loading times for apps
  • Reduce delays when switching between apps
  • Fix battery drain from rogue cached processes
  • Free up storage space on your device

How to Clear Cache for Individual Apps

You can clear the cache for specific apps if you are having issues with only that particular app. Here are the steps:

  1. Open the Settings app on your S21.
  2. Tap on Apps.
  3. Tap on the Menu icon in the top right and enable Show System Apps.
  4. Locate the app you want to clear cache for, tap on it.
  5. Tap Storage.
  6. Tap Clear Cache. This will wipe the app cache.

Doing this for apps like Chrome, Gmail, or Facebook can help fix issues or speed them up if they are running slow or glitchy.

How to Wipe the Entire Cache Partition

This will give your phone a fresh start by wiping temporary data for all apps and services. It’s a quick way to troubleshoot any performance issues.

Use Device Care to Manage Cache

Samsung provides a built-in maintenance tool called Device Care that can help automatically manage cache and other device optimizations. Here’s how to use it:

FAQs about Clearing Cache on the Galaxy S21

Here are some frequently asked questions about wiping cache on the S21:

Is it safe to wipe cache partition?

Yes, wiping cache is completely safe. It will not delete any of your personal data like photos, downloads, or messages.

How often should I clear cache?

Most people clear cache every few weeks for optimal performance. But you can do it more frequently if you notice apps slowing down.

Will I lose app data if I wipe cache?

No, your app data like logins, preferences, and saved information will not be lost when clearing cache.

Troubleshooting Tip: Check Storage Space

Many performance issues stem from insufficient storage space on your S21. Try checking how much free space you have and free up more if needed:

  • Go to Settings > Battery and Device Care
  • Select Storage
  • Check how much free space you have left
  • Delete unused apps, photos, videos to free up space

Having at least 15% storage space free is recommended. Running out of storage can cause slowdowns and glitches.
