Do you keep getting the annoying “System UI isn’t responding” prompt on your Android device? If you do, you’re at the right place. How do you fix it, though? In this guide, we’ll walk you through several steps you can try to fix the “System UI Not Responding” error.
Why Is System UI Not Responding?
There are a couple of reasons why the System UI might not be responding. We’ve listed below the most common:
- Lack of storage space
- App preferences
- Your phone may have a malware
- Apps from unknown sources
- Memory card not inserted properly
- Google updates and third-party applications
How to Fix The “System UI Not Responding” Error
Below are all the tips that will help you to fix it when your phone shows the “System UI not responding” error. Let’s check them out.
1. Restart Your Phone
This is usually the first thing to do when facing a problem with any electronic device. A restart resets your phone, clears up used RAM, and fixes most bugs and issues.
To restart your phone, follow these simple steps:
- Long-press the ON/OFF button at the side of your device until you get a prompt like the one below. It may look different depending on the brand of your Android phone.
You would be asked whether you want to shut down, restart, or turn on Emergency Mode.
- Tap on “Restart” and wait for your device to power off and then on by itself.
This should fix the error. If it doesn’t, please try the other fixes below.
2. Clear System UI and Google Play Services Cache
Sometimes, app cache can stop an app from functioning correctly. The System UI app is no different.
- Open Settings on your device and go to Apps or App Management
- Once you are in the Apps list, click on the dots menu and select Show Systems Apps.
- Search for “System UI“ in the search bar and open it.
- Now, click on Force Stop and then Storage. (You might get a prompt asking if you want to force stop the application. Click OK.)
- When you get into Storage, click on Clear Cache. This will clear the cache of the System UI application.
- Search for Google Play Services, open it, and click on Storage.
- Next, click on Clear Cache at the bottom right of the screen.
- This should fix the problem. If it doesn’t, you can go to Manage Storage and then Clear All Data.
Now, restart your phone. Check to see if this has fixed the UI responsiveness problem.
3. Check Memory Card
When it comes to smartphones, SD cards are almost a thing of the past. However, there’re still many great phones that include an SD card.
If your phone doesn’t have an SD card you can skip this step. In case, your phone comes with an SD card, you’ll want to make sure it’s inserted properly or not bad.
- Head to “Settings” and open “Storage“.
- Tap “Unmount SD Card” and tap OK to confirm your decision.
Remove the SD card from your phone and check for any defect or dust. Wipe the SD card with a microfiber cloth and insert it back into the memory card slot.
Check to see if this resolved the problem. If the UI is still not responding on your phone, move on to the next step.
4. Uninstall Google App Updates
Sometimes, Google updates might be incompatible with your device and cause some errors. To uninstall these updates, follow these steps:
- Go to the Google Play Store app and search for “Google“. When it opens, click on Uninstall.
- You will receive a prompt asking if you want to uninstall all updates. Click the Uninstall button to uninstall the app.
After uninstalling, restart your device and check to see if you are still having an issue.
5. Uninstall Apps from Unknown Sources
Installing apps such as APK files from unknown sources is not a good idea. These apps may contain malware that can deliberately infect your device, compromising its security.
Speaking of malware, you should check our guide on how to protect your phone from hackers.
To uninstall these apps, follow the steps below:
- Go to Settings and then click on Apps.
- Select the app of your choice and click Uninstall at the bottom of the screen.
6. Clear App Cache
This can be a manual and tiring fix but it has been proved to work most of the time. Clearing the app cache can help to free up space on your Android phone.
- Go to Settings and then click on Apps
- Select an app in the Apps list, go to Storage, and click on Clear Cache at the bottom of the screen.
Do this for other apps, especially those that use up a lot of memory.
7. Factory Data Reset Your Device
If all fails, you might have to settle for a more drastic measure. You’ll need to factory reset your Android phone.
Keep in mind that this will erase all data including files, accounts, data, and downloaded apps from your phone.
To factory reset your phone, follow these steps:
- Go to Settings and click on General Management.
- Click on Reset.
- Choose Factory Data Reset. This will take your device back to its original factory settings.
- Click on the Reset button to reset your phone.
You have now restored your device to factory settings. Restart your device now, the error should be gone for good.
