FIX: com.process.systemui has stopped

One of the most common errors plaguing the Android Operating System is the “com.android.systemui has stopped” error, an issue in which the entire User Interface of a device ceases to respond, sometimes for as long as an hour.

unfortunately, the process.com.android.systemui has stopped error

This error can be caused by anything from a faulty custom ROM installation to a deleted OS file or a third-party app. In most cases, it is a third-party app. A couple of users have reported issues with the Firefox app causing this.

The following are the most effective methods that can be used to solve this problem:

Method 1: Download and Run CM Security.

  1. Many users in the comments on this post suggested that running CM Security fixed the issue for them.
  2. Go to the Play Store and search for CM Security, or click (here).
  3. Install the CM Security app and run
  4. Scan with it, and the issue should be resolved.

Method 2: Wipe the device’s cache partition.

Sometimes, wiping the cache partition on your device can fix this particular issue. To do that, follow the steps below.

  1. Switch the device off.
  2.  Boot the device into Recovery Mode, which on most devices is done by pressing and holding the Power, Volume Up, and Home buttons simultaneously.
  3. Once the device has entered Recovery Mode, use the Volume Rocker to highlight the ‘Wipe Cache Partition‘ option.
    Navigating down to the “Wipe Cache Partition option”
  4. Press the Power Button to confirm the selection.
  5. Wait for the device to successfully wipe its cache, and then reboot the device.

Method 3: Eliminate any third-party apps that might be responsible.

First and foremost, ensure the “com.android.systemui has stopped” error is indeed caused by a third-party app by booting the device into Safe Mode and using it for some time to confirm that the error does not appear.

Browse through the apps on the device to determine which app caused the issue. Essentially, this means that the problematic app is the one installed immediately prior to the emergence of the issue.

Eliminate any and all apps that you find suspicious, then exit Safe Mode. If there is more than one suspect, reinstall the deleted apps one at a time to determine which app is the actual culprit.

Method 4: Reinstall or change the device’s ROM (for rooted users)

 If the device is rooted and a custom ROM has been installed on it, the problem might be the fact that the device’s data and cache were not appropriately wiped after the installation of the ROM.

 If that is the case, all the user needs to do is reinstall the ROM or switch to a completely new one, ensuring that they remember to wipe the device’s data and cache partition this time.

Method 5: Uninstalling Google Updates.

In some cases, the Google updates installed after connecting the phone to an internet connection might have been the culprit behind this error. Actually, the updates may not be entirely compatible with your Android operating system, which is why this error is being triggered. To uninstall these updates:

  1. Drag down the notification panel and select the “Settings” option.
  2. Click on the “Applications” button in Settings, and then select the “Apps” button.
    Clicking on the “Applications” option
  3. Click on the “Three Dots” in the top right corner and select “Show System Apps.
  4. Scroll down the list of applications and tap on the “Google App” option.
  5. Click on the ‘Uninstall Updates’ button to uninstall all the installed updates for the Google App.
    Uninstall Updates of Google Play Services
  6. Confirm any on-screen prompts and wait for the uninstallation to be completed.
  7. Check and see if the error persists after uninstalling Google updates.

Method 6: Clearing Cache/Data

It is also possible that a particular cache storage on your phone has been corrupted, due to which this issue is being triggered when Google Play Store tries to launch using that corrupted cache. Therefore, we will clear it in this step. To do so:

  1. Tap on the “Settings” option from your home screen to access the settings.
  2. Click on the “Applications” option, and then select the “Apps” button to launch the application management panel.
    Clicking on the “Applications” option
  3. In this panel, click on the “Three Dots” at the top right corner and select “Show System Apps” from the list.
  4. In the system apps, scroll down and click on the “Google Play Store” option.
  5. Click on the “Storage” option, and then click on the “Clear Cache” button.
    Tap on Clear Cache
  6. Wait for some time and then click on the “Clear Data” button.
  7. Confirm any on-screen prompts during this period and check whether the issue still persists.

Method 7: Disabling Auto-updates.

In certain situations, the auto-updates queued by the Play Store might cause this issue on your phone. Therefore, in this step, we will disable these auto-updates from being triggered on your mobile. To do that:

  1. Tap on the Google Play Store icon on your home screen or app drawer to launch the Play Store.
  2. In the Play Store, click on the “Menu” button and select “Settings.
  3. In the Settings, under the General window, click on the “Auto-Update Apps” option.
    Selecting Do not auto-update apps
  4. Select the “Do not auto-update apps” option from the next screen and click on “OK.
  5. Check and see if doing so fixes the issue on your mobile device.

Method 8: Disable Auto-Start Management.

Some applications on your mobile are granted permission to auto-start at their own discretion. While this can be a useful feature in some cases, in others, it constitutes a security breach due to device threats. Therefore, in this step, we will temporarily disable this feature and then check if doing so resolves the issue with your Android smartphone.

  1. Drag down the notification panel and click on the ‘settings‘ option.
    Dragging down the notifications panel and tapping on the “Settings” option
  2. In the settings, scroll down and select the ‘Security‘ button, then click on the ‘Auto-start Management‘ entry.

  4. Uncheck the option for all the applications on the list, and save your changes if the option is given.
  5. Check and see if doing so fixes the issue for your Android device.

Method 9: Clearing the System Interface Cache.

There is a system interface process among the background processes, and it is a very important background process because it adds a lot of interface functionality to your device. However, if it acquires corrupted cache, it may stop functioning properly, which can ultimately trigger this issue. To fix this error, we will need to clear its cache. To do so:”.

  1. Tap on the “Settings” option from your home screen to access the settings.
  2. Click on the “Applications” option, and then select the “Apps” button to launch the application management panel.
    Clicking on the “Applications” option
  3. In this panel, click on the “Three Dots” at the top right and select “Show System Apps” from the list.
  4. In the system apps window, select the “System Interface” entry and choose the “Storage” option.
  5. Click on the “Clear Cache” and “Clear Data” buttons, and wait for both of them to be cleared.
    Tap on Clear Cache
  6. Check and see if the error message is fixed after doing so.           

Method 10: Allowing System UI to Draw on Top.

It is possible that, due to a potential permissions reset, the System UI process has lost the permissions to draw on top of other applications, which is causing this particular issue. To fix this, we will restore its permissions, which should resolve the problem. To do so:

  1. Tap on “Settings” from your home screen or app drawer.
  2. Click on “Applications” and then on “Application Manager.
    Opening Settings and tapping on the “Applications” option
  3. Click on the “Three Dots” at the top right, and then select “Apps That Can Appear at Top.
  4. Click on the “Three Dots” again and select the “Show System Apps” option.
  5. Click on “System UI” from the list and change its permission from Off to On.
  6. This should fix the issue, make sure to check if the error pops up again.
