The Android operating system has long been recognized by many as the best platform for mobile devices. This is not said as an insult to fans of Apple products, this is just a statement of fact, which you can argue with, but you can’t argue with it. Despite such colossal popularity, and partly, perhaps, precisely because of it, there are simply an immense number of different bugs and errors in devices running the Android OS. In fairness, it is worth noting that some of this majority is the result of rash actions on the part of the user, including third-party software. This article, like many others, is designed to help fans of the “green robot” quickly find their way and find a detailed explanation of the reasons and how to correct possible system errors. And as is already clear from the title of the article, the error “The com.android.systemui process has stopped” will be considered.
What it is
Of course, the most important question in a situation where an error has occurred in the Com Android SystemUI application is what to do in such a situation.
But before solving the problem, you need to at least roughly understand what we are talking about and what the user of the Android device is faced with.
It’s not difficult to figure out what kind of program it is and what functions Com Android SystemUI performs. We are talking about a system application here. It is responsible for correctly setting up the user's graphical interface in the shell of the mobile operating platform. That is Android. It is one of the essential services. Because of this, disabling it can lead to quite unpredictable and undesirable consequences.
When faced with a notification that, unfortunately, the running Com Android SystemUI system process in Android has stopped, one of the following reasons is possible:
- the system application conflicts with the installed software;
- there was a software failure;
- a virus appeared in the system.
Annoying error
Among all the errors typical for this series of devices, the most unpleasant for the user is the one in which the Samsung Galaxy system ui application is displayed on the display.
IMPORTANT! Some users have to deal with such incorrect operation of their smartphone every day, which significantly reduces its ease of use.
Typically, there are several actions that can cause such manifestations. Among them:
- Pressing the Home button;
- Launching some applications or games;
- Use of Google services, camera and other useful features.
Since these elements are usually used on a smartphone constantly, it is difficult to overestimate the importance of eliminating this unpleasant problem.
Bug fix
At the moment, there are several effective methods to eliminate such behavior of the device. The most optimal method seems to involve working with Google components.
To resolve the error, you must go to the application store, where you go to the My games and applications section. Among the installed components, you will need to find a special Google program, which was previously called Google Search. In it, you need to disable auto-updates, and then delete all existing updates. This will correct the error in the vast majority of cases.
If the problem persists, it makes sense to try another method. You need to go to the settings of your smartphone, where in the Applications tab select Show system applications. There you should find the System Interface, from which you need to delete data files.
Despite the fact that the above methods demonstrate effectiveness in most situations, in some cases they are powerless. If they did not help, it makes sense to do so after archiving the necessary data. This is guaranteed to help fix the problem and avoid file loss.
It did not bring global changes, but still new interesting features appeared in the OS: Doze, Android Pay, ; although, of course, there was a “fly in the ointment” - . However, Google, unlike other companies, cares not only about ordinary users, but also about developers - the System UI Tuner was introduced especially for them. For “unenlightened” users, I’ll note that SystemUI is a system application located in system/app and is responsible for some interface elements, in particular the status bar, notification panel and quick settings panel - roughly speaking, the “curtain”. Android users have long been interested in this interface idea: they installed custom firmware, various modifications like the Xposed Framework, and ultimately “stitched” *.apk from parallel interface shells. Now the search giant has met halfway and added a piece of functionality to its system, with some unique features, which we will tell you about today.
Causes and solutions
Next to the question of how to fix the situation if the Com Android SystemUI error appeared and the application was stopped.
There are several solutions here. Namely:
- reboot the device;
- disable automatic date and time detection;
- remove Google updates;
- clear SystemUI data;
- get rid of viruses;
- reset the device to factory settings.
Now about each method of solving the problem separately.
Reboot
A trivial, but sometimes effective option, how to remove an error associated with the Com Android SystemUI system application.
To do this, just restart your Android device. Practice shows that in many situations this solution helps a lot.
If after a reboot the error appears again, you need to take more drastic action.
Cleaning SystemUI
It is also possible that the error is caused by incorrect data in the auxiliary files of the system application. To solve the problem, you just need to delete these files.
To do this you need:
- go to “Settings”;
- open "Application Manager";
- go to the “All” tab;
- find the SystemUI application;
- open its properties;
- first clear the cache;
- then clear the data.
All that remains is to reboot the device. It would be useful to simultaneously use utilities to clean up system garbage.
Google updates
As for this error, it has already lost its relevance on new versions of the OS and belongs to the category in which all the blame (or most of it) is placed on the system's pre-installed software, which for some reason (probably known to the developers) has ceased to work. carry out assigned tasks in a normal manner. So, as has already been repeatedly documented in practical research, the main blame for the error should be placed on updating service components from Google. Therefore, the first thing you need to try is to remove “Google” (yes, it sounds “hackery”) and subsequently install the software again, and for this you will need:
- open the Google Play application (or Play Market);
- enter “Google” into the search bar;
- in response to your search request, a list of services available in the store will open, in the first place of which will be the software you need now;
- open it, click “Delete” and confirm your desire in the “Delete all updates for this system application” window;
- wait for deletion and check the functionality of the mobile device;
- If the error has been resolved, you can return the removed software.
If these steps do not lead to the desired result, then try the following alternatives:
Option 1. “Checking the set date and time”:
- open the “Settings” – “Advanced settings” section and go to “Date and time”;
- deactivate the “Network date and time” item and restart your smartphone/tablet;
- If the indicators are wrong, set the date and time manually.
Option 2. “Clear cache”:
- open Settings again, but this time go to the Applications category;
- select “All applications” and enter “com.android.systemui” in the search bar;
- expand the detailed information about the found option and click “Erase data” and “Clear cache” one after the other;
- reboot your mobile device again.
Method 1: Clear cache memory
- Turn off your Android device.
- Boot your smartphone or tablet into recovery mode . Most Android devices use a combination of the Volume Up and Power keys to enter Recovery Mode. Read the following article - how to switch to recovery mode.
- Once you are in Recovery Mode, use the Volume key to select the Wipe Cache Partition .
- Next, press the power button to confirm your selection.
- Wait until the device clears the cache memory, then restart your smartphone or tablet.
Is it a virus or not?
Before you remove the Com Android SystemUI system application, you need to understand whether the file is a virus, or whether there is simply an error that needs to be fixed without hasty removal.
And to do this, you need to understand how the virus behaves. It tries to disguise itself as a system file and often starts downloading third-party applications without user consent. The latter lead to the appearance of advertising and more. Moreover, advertising is mostly intrusive in nature, and its subject matter is obscene.
A Trojan can penetrate a system if:
- custom firmware of the mobile operating system was performed;
- questionable sources were used to download applications;
- installing one-day applications from the Market;
- files were downloaded from the Internet, instant messengers, email containing malware, etc.
Therefore, it is worth remembering exactly when you noticed the message that the application, called the system UI, has been stopped. If this coincides with downloading some application or file, there is a chance that you have a virus.
It will also be useful to look at the creation date of the Com Android SystemUI file. This can be done through the regular application manager by looking at the file properties. If the date is identical to other system files, it is simply an error. If the file was created recently, you almost certainly have a virus.
The malware operates as follows:
Once downloaded and installed discreetly, it starts downloading various adware applications from the Internet. Among them, unreliable and very dubious browsers, memory cleaning programs, and much more often appear.
And every time you simply open an application on your phone, even one that was installed before the Trojan appeared, new advertisements will appear on the screen. Moreover, it can block your view, preventing you from properly perceiving information. Naturally, then it is quite reasonable to ask, how did he penetrate and bypass the anti-virus protection of the phone?
Viral activity
It is also necessary to clarify that the causes of the error in question may be related to the activity of virus software. What kind of viruses these could be and how they got into the system does not really matter, but thinking about what actions you took that caused the problems would be the right decision. Think about what you have installed recently. This could be any third-party products, including those installed not through a store, but manually from an “.apk” file, downloading any files from the vast space of the Internet, etc. It is worth understanding that viruses can pretend to be system viruses components and in this regard it would be useful to check the creation date of “com.android.systemui”. This circumstance may lead to the fact that it is simply not possible to remove malware using simple/standard means.
There are two solutions here. The first, which is also more complex, is to obtain super user rights (aka root rights) in any accessible and understandable way and use extended powers to delete “everything your heart desires” (of course, within reasonable limits). The second is to roll back the configuration of the mobile device to factory settings while preserving all personal data. For obvious reasons, both the first and second methods should be used only if none of the above helped, and the likelihood that the error arose as a result of malicious influence is supported by facts.
When the “System is not responding” error pops up
A System related error can occur for a variety of reasons:
- Insufficient memory. For correct operation of the device, it is recommended to keep at least 300 MB of internal memory free.
- Running applications that require too many resources. Sometimes the device does not have enough power to ensure the correct operation of the smartphone. For example, a failure may occur in a situation where two “heavy” games are launched simultaneously on a weak device with a small amount of free RAM.
- SD card malfunction. A warning that System is not responding may occur if the SIM card is damaged. If the problem disappears after removing it, you will most likely have to buy a new external drive.
- Failure to update the operating system or applications in a timely manner.
- Downloading virus software.
- Problem with root rights. If the user has access to root rights - superuser rights necessary to modify the OS, this can periodically cause errors in the functioning of the smartphone.
In difficult cases, service repair will help.
