Samsung Galaxy S9 and S9 Plus

If you own the Samsung Galaxy S9 or Galaxy S9 Plus, users may have problems on the phone that can be easily solved using two different troubleshooting solutions, which will only take a few minutes to complete. The same issues can be found on most Android-based devices. The top method to fix any bugs or software glitches on your Galaxy S9 or Galaxy S9 Plus is to either complete a factory reset or perform a cache wipe.

By clearing the cache on a Samsung Galaxy S9 and Galaxy S9 Plus, you can fix issues such as lag, glitches, or freezing by following the guide below. It doesn’t delete as much data as a factory reset, and the data it does delete is temporary and largely unimportant, so you don’t need to worry about any of your files. Considering that, it’s usually best to try this method first when you’re troubleshooting an issue.

What is the cache and what does it do?

So, what is the Cache and why should it be cleared on your Galaxy smartphone? The Samsung Galaxy S9 and Galaxy S9 Plus have not just one type of cache, but two different types. The first is for the apps and the other one is for the system. Fittingly, these are call the app cache and the system cache respectively. Any app you install on your Galaxy S9 or Galaxy S9 Plus has it’s own cache installed. It allows temporary data to be stored for better, more efficient use when switching between apps. The system cache is almost exactly the same, but instead of storing app data it does the same for the Android OS software. This is why, when an issue appears with apps crashing or freezing, the best option is to clear the app cache or the system cache, to help resolve the issue.

How to Clear the App Cache on the Galaxy S9

In the newest version of Samsung’s TouchWiz Launcher, there isn’t an option to clear an app’s cached data individually. TouchWiz is just Samsung’s take on the customizable Android OS. In the current version (Oreo), each app’s cache is located in a system cache that gets cleared regularly by default. So users coming from earlier versions might be confused when trying to clear a few extra MB of storage or fix an in-app behavior problem. There’s good news, though! The new system makes clearing storage space even easier. There’s a dedicated device manager that will monitor power, storage, and RAM. This manager can improve efficiency with a single tap. To do this, follow the steps below:

  1. Go to your Settings, either from your App list or from your notification drawer.
  2. Open Device Maintenance.
  3. Tap on Storage.
  4. You’ll see a rundown of which types of data are taking up the most space.
  5. You can tap on individual items to delete things in that category.
  6. Then select CLEAN NOW to free up the amount of space indicated on the button.
  7. This process only clears cached, temporary, and trashed data.
  8. User data like photos, music, videos, and apps are safe. Delete user data using step 5.

What to do when clearing the app cache doesn’t help

If you have cleared the cache of the individual apps and you are still having the same problems on your Samsung Galaxy S9 or Galaxy S9 Plus, then the next best solution is to uninstall the apps that are causing the issues and reboot the device. If the Samsung Galaxy S9 or Galaxy S9 Plus has restarted and the problem is still occurring, then we suggest that you perform a system cache wipe (also known as wiping the cache partition on the Galaxy S9 or Galaxy S9 Plus).

How to Clear the System Cache on the Galaxy S9:

  1. Start by turning the Galaxy S9 or Galaxy S9 Plus off.
  2. Then hold the Volume Up, Power and Home buttons all at the same time, until you see the Android logo appear and the phone vibrates.
  3. You can release the buttons when Recovery Mode starts to boot.
  4. Next, use the Volume buttons to scroll down and highlight the Wipe Cache Partition option.
  5. Once it’s highlighted, press the Power button to select it.
  6. Scroll down to Yes with the Volume button, and press the Power button to select it.
  7. Navigate to the Reboot System Now option and press the Power button to select it.
  8. Finally, your Galaxy S9 should reboot with a cleared system cache.

If the problems persist, the next stage is to factory reset the Galaxy S9. If it comes to this, remember to back up everything on the phone, as a factory reset will delete all of your data.
