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
  2. Clear System UI and Google Play Services Cache
  3. Check Memory Card

  7. Factory Data Reset Your Device

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

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.

  1. Head to “Settings” and open “Storage“.
  2. 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.

After uninstalling, restart your device and check to see if you are still having an issue.

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.

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.

Make sure to back up your phone to the cloud storage of your choice or on an external storage device before resetting your device.

To factory reset your phone, follow these steps:

  • Go to Settings and click on General Management.
