This guide will show you how to clear the cache on your Galaxy S8 or Galaxy S8+ and explain why you want to do it. We will explain in detail the steps to clear your phone’s app cache and system cache. Whether you’re trying to free up space or are dealing with Galaxy S8 issues, this is an important step to take.
Unlike a factory data reset, wiping the cache partition will not delete any personal data on the Galaxy S8. This clears temporary files in two different areas of your device storage and memory. First we’ll quickly show you how to clear both in our video, then we’ll explain the cache and share step-by-step instructions below.
So what is “cache”? When you open or use apps, they store files, data or information for later use. That way, the phone or app will be faster the next time you use it. For example, when you load Instagram, it caches many apps, including autoplay videos, that way the app “just works” when you swipe your feed.
Sometimes cached information takes up too much space or causes an app to malfunction. A similar situation occurs with every software update on the Galaxy S8. So clearing the system cache is an essential step in most of the guides on how to fix problems with your phone. It cleans leftovers from apps or updates and gives your phone a fresh start. If you haven’t watched our video, here’s how to do it.
How to Clear System Cache on Galaxy S8
Make sure to turn off the phone, then simultaneously press and hold the three buttons from the first step. Keep them pressed the entire time you see “Galaxy S8” on the screen. Let go when you see the blue Android. Then, the rest is pretty simple. Do not select “factory data reset” as it will wipe your entire device. So be careful. Restart your phone and you’re done.
How to Clear App Cache on Galaxy S8
Another common step is to clear the app cache on smartphones. This fixes a malfunctioning app or frees up space when something like Instagram or Facebook starts using too much space after months of use. Each application temporarily stores information. And gradually, this cache starts to accumulate and you may run out of space on your phone. Here’s how to clear each app’s own cache.
Just select the Clear Cache option and don’t touch the Clear Data button. Otherwise, your Galaxy S8 will delete all data associated with that app, including settings or login information. And while that won’t cause any problems, it’s frustrating to deal with.
If you delete Instagram data, you have to sign in again and then change any settings or options. It deletes everything similar to uninstalling an app without actually uninstalling it. Keep this in mind before continuing.
When Should You Clear the Cache?
So when should you clear an app’s cache or your phone’s cache? You will most likely never have to do this. And while it might help after a major update like the Galaxy Android 8.0 Oreo update, you still don’t need it. However, if an app starts to misbehave or “feel” slow and laggy, this is a good place to start. Clear the cache first, then try uninstalling and reinstalling.
