One of the most common errors that the Android Operating System is plagued by is the “com.android.systemui has stopped” error, an error in which the entire User Interface of a device stops responding, 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.

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

Method 1: Download and Run CM Security

  1. Many users from 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 it
  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. In order 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: Get rid of any third-party apps that might be responsible

First and foremost, make sure that the “com.android.systemui has stopped” error is indeed being caused by a third-party app by booting the device into Safe Mode and using it for a while to make sure that the error doesn’t pop up.

Browse through the apps on the device to determine what app gave rise to the issue. This basically means that the culprit is the app after the installation of which the issue was born.

Get rid of any and all apps that you find to be suspicious and boot out of the Safe mode, and in the event that there is more than one suspect, reinstall the deleted apps one by one to determine what 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 onto 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, making sure 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’ve been the culprit behind this error.

  2. Click on the “applications” button in settings and then select the “Apps” button.

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 due to which it is facing this particular issue. In order to fix this, we will be giving it back its permissions which should get rid of the issue. For that:

  1. Tap on “Settings” from your home screen or app drawer.
