In this quick guide, we will show you how to clear cache on Galaxy S9 or Galaxy S9+. Next, we’ll explain why you want it and when you should do it. We will detail the steps to clear both app cache and system cache on Galaxy S9.
Whether you’re trying to free up space or are dealing with Galaxy S9 issues, this is an important step to take. Unlike a factory data reset, wiping the cache partition does not delete any personal data. This will delete temporary files in your device storage and memory.
If you’re wondering what “cache” is for a start, let’s explain. Every time you use an app, it stores files, data, or information for use later or the next time you open it. This makes your phone faster and apps run better. For example, when you load Instagram, it caches many apps, including autoplay videos, this way everything loads quickly, smoothly, and instantly for you.
But sometimes the cache takes up too much space or causes an app to malfunction. As a result, most of the Galaxy S9 troubleshooting guides mention clearing the cache at some point. We experience a similar situation after every major software update. That’s why clearing the system cache is an important step to keep your phone in optimum performance. It cleans leftovers from apps or updates and gives your phone a fresh start. If you haven’t watched our video above, here are the step-by-step instructions.
How to Clear System Cache on Galaxy S9
As long as you follow the steps above, this whole process only takes about a minute. If it doesn’t boot into recovery, turn off your phone and try again. Make sure to hold down all three buttons until you see the blue Android, then release.
As a precaution, do not select “factory data reset” as it will wipe your entire device. Just be careful here, that’s all.
How to Clear App Cache on Galaxy S9
Another step you will want to learn or do is to clear the cache for certain apps on your phone. This fixes a malfunctioning app or frees up space when something like Instagram or Facebook is using too much space. This is because all your apps store information temporarily. 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.
It’s that simple. Tap “clear cache” for the app in question and you’re done. Your Galaxy S9 will delete all these temporary files and the app should work fine now. Make sure you don’t touch clear data otherwise it will delete everything for that app as well. Like settings, preferences, login or data and more.
When Should You Clear the Cache?
In closing, you’re probably wondering when you really need to clear the cache for an app or your phone. The answer to that is technically never. You will most likely never need to clear the caches on your device. And while it might help after a major update like the Galaxy Android 9.0 P update later this year, 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.
