How to troubleshoot Play Store error 18 on Samsung Galaxy S10

These troubleshooting procedures are very effective in fixing problems like this. One of them may be able to fix the Play Store error 18 on your Galaxy S10 considering the fact that it’s not really a serious problem. With that being said, here are the things you need to do to try and fix this problem.

First Solution: Do a Forced Restart

Before anything else, we need to determine if a glitch in the system is causing the issue on your Galaxy S10. This is a simulated battery procedure that refreshes phone’s memory and reload all core services running in the system. Here’s how:

Press and hold the Volume Down button and don’t release it yet.
While holding down the volume button, press and hold the Power key as well.
Keep both keys held down together for 15 seconds or until the Galaxy S10 logo shows on the screen.

Once the phone has finished rebooting, try to open the Play Store and download any app to see if the error 18 still pops up. If it still does, then move on to the next procedure.

Second Solution: Delete Play Store Cache and Data

If Play Store cache and data are corrupt or outdated there is a chance that the app will function abnormally and triggers different types of app issues like the error code 18. So, this time, we recommend you to delete its files and data to bring your Play Store app back to default settings.

Open Settings app.
Tap Apps.
Tap the More settings icon (three-dot icon, upper right).
Tap Show system apps.
Find and tap the Google Play Store app.
Tap Storage.
Tap Clear cache button.
Tap Clear data button.
Tap OK.

When the method is done, open again your Play Store and observe closely if the issue still occurs. If the error 18 still shows, jump over to the next step.

Third Solution: Uninstall Play Store Updates

Another possibility to consider here is that there could be something wrong with the app itself especially if it had been updated recently. It’s possible that the update is messing it up. Thus, we will try to uninstall the Play Store update to see if it will work on your device.This is how to do the method:

Open Settings app.
Tap Apps.
Tap the More settings icon (three-dot icon, upper right).
Tap Show system apps.
Find and tap the Google Play Store app.
Tap the three-dot icon at the upper right.
Tap Uninstall updates.

After this, it’s best to restart your phone to refresh its memory as well as the app.

Fourth Solution: Try to Free your Storage Space

Sometimes, the error 18 appears if the internal storage doesn’t enough available space left. So, what we have to do is to verify and transfer some of your apps from internal storage to your SD card.

You may transfer your photos, videos or anything as long as you can create some space. If it’s really the case, then the error 18 shouldn’t pop up once you’ve transferred some of your files to an external storage device. If it continues to bug you, however, then try the next procedure.
