How to clear the cache on your Samsung Galaxy phone to help it run more efficiently

Galaxy S10

  • If your Samsung Galaxy phone is running slowly or low on storage space, knowing how to clear the cache on your Galaxy can clear up the device to help it run more efficiently.
  • Your Samsung Galaxy uses a cache to store temporary files for the apps on your phone. This cache can become bloated, and take up excess space or even slow down the phone.
  • If an app is crashing or behaving badly, you might also try clearing its cache to see if that solves the problem.

When your Samsung Galaxy runs low on memory or starts behaving strangely, you should clear the phone’s cache. 

The cache is filled with temporary data that’s used by apps. This cache can help apps run faster and keep track of information they need to perform tasks. 

But the cache can, over time, get quite large, robbing you of storage space. And if an app behaves strangely, corrupted data in the cache might be to blame. 

You have two choices: You can clear the entire cache on your Galaxy with a single tap (which is convenient if your goal is to reclaim storage space) or you can clear specific apps’ caches (best if you are troubleshooting a buggy app). 

Either way, clearing the cache does not delete important data; it only discards temporary working files.

Be careful not to tap “Clear data,” or you will erase the app’s data. This will essentially return it to the way it was when you first installed it, meaning that you may lose personal data in the process.
