Samsung's "System UI app is not responding" error annoys many Android owners. This bug appears not only on Galaxy; owners of Xiaomi, Sony and other latest generation smartphones suffer from it. One can speculate endlessly about the reasons for the dysfunction of SystemUI, but the device must be saved. Read a life hack that will help you get rid of the problem.
How does the error manifest itself?
This system bug is mostly noticed by owners of Samsung gadgets. A pop-up message appears on the device screen with the following content: “The com.android.systemui process has been suspended.” When might it occur?
You pressed the “Home” button, turned on the camera, launched the game, application, and went to the Play Market.
What is this Android system UI? The phrase com.android.systemui denotes a service that is responsible for the correct settings of the user graphical interface in Android. It is one of the main ones, which is why it is highly undesirable to disable it.
The appearance of such an error on phones is a widespread phenomenon. It appears especially often after clicking on Home. Samsung owners associate this bug with the latest “crooked” update for the platform. This caused the problem of working both with this service and with a number of others.
If the “Android System UI has stopped” window appears, what should I do? We will present you three effective ways to fix the problem.
Types of user interface
User interfaces can be gestural, tactile, voice, graphical, command line, and even neural.
Command Line Interface and Text Interface (CLI) The command line is still very popular among system administrators and programmers. This is one of the first methods of interacting with a computer. It has a special charm - it creates a feeling of one-on-one communication with the machine without intermediaries. The command line is like an endless A4 sheet on which the user enters command text and receives the results of the work in the form of text.
Graphical User Interface (GUI) The most popular type of UI. It is a window with various controls. Users interact with them using the keyboard, mouse and voice commands: they press buttons, poke with a mouse, swipe with a finger.
Gesture, voice, tactile, neural “Any sufficiently developed technology is indistinguishable from magic,” the English science fiction writer and futurist Arthur Clarke once said.
For example, through the Voice User Interface you can give commands to your smartphone through voice assistants: Siri from Apple, Alexa from Amazon or Alice from Yandex.
NUI (gestural, natural) is used in games for Xbox, Nintendo Wii or PlayStation consoles. You will find the same technology in smart home equipment, for example, when turning on the lights or adjusting the volume of Yandex.Station by changing the position of your hand.
Manufacturers are pumping up technology and expanding the capabilities of machines, and you can even enjoy new gadget features by sending thoughts directly to the computer.
Solution one
We figured out that this is the Android system UI. Now let's see how to restore the service to work properly:
- Go to the Play Store application. Type Google in the search bar.
- The application of the same name will appear first in the list. Remove it.
- Next you will see a similar window: “Do you want to remove all updates for this program?” Confirm this action.
- Press the “Home” key again, turn on the camera, go to the application that caused the error to appear when you entered it. If now the annoying window does not appear, then the problem is solved.
When these actions do not lead to anything, you should deactivate auto-update in the settings. This action will help avoid the bug from appearing before the new update for the Android OS.
Solution two
Many people ask: “When an Android system UI error occurs, how do I reboot the device?” We advise you to go a slightly different route:
- Go to the settings menu, find the “Applications” section.
- Now click on the “Menu” button.
- In the list that appears, select “Show system applications”.
- Among the presented ones, find “System Interface”.
- Go to its "Memory" section. Clear all data as well as cache.
After these manipulations, the system error should disappear. If this does not happen, then you can think about taking such a radical measure as resetting to factory settings. But before that, be sure to make a backup copy of all important data stored on your gadget.
User Interface Elements, Syntax, and Other Features
Interface elements in the GUI are implemented based on metaphors. Metaphors must already be familiar to users or fit into their cultural context (then they can be taught).
Metaphors in interfaces based on mental models All interface elements together form a single design concept (metaphor). For example, Trello (a task management system) visually looks like a SCRUM project management board (metaphorically), and you can also drag sticky notes from one column to another. Trello was originally invented by programmers who are very close to the SCRUM concept.
Example UI elements, syntax and other features.
Popular interface elements: Button, Link, Icon, Tab, Checkbox, Radio button, Switch, Drop-down list, Slider, Input field, Tables, Menu.
Interfaces are designed according to the principles of atomic design. Atomic design is an approach to dividing a system of any complexity into parts, small elements - atoms. Atoms can be reused and combined with each other.
Atoms. The smallest particles that make up the interface: buttons, input fields, checkboxes, radio buttons, typography styles.
Atomic level.
Molecules (groups of atoms) . If you take two atoms and combine them with each other, you get a molecule. For example, a button and an input field.
Molecular level.
Organisms. If you combine several molecules, you get an organism - a large part of the interface. For example, end-to-end navigation in the header or sidebar of the site.
Level of organisms.
Templates. If you combine organisms with each other and create a template, you will get an interface designed to solve typical problems.
Template level.
Solution three
If, when figuring out that this is “Android system UI has stopped,” you remember that such an inscription appeared on the smartphone screen earlier, long before the release of the ill-fated update, then you need to go a different way:
- Go to the “Settings” menu, scroll to “Application Manager”. We will need the “Everything” tab.
- In the specified section, find “System UI”.
- First of all, click on the “Clear cache” button.
- After this action, tap on “Stop”.
- Now restart your smartphone.
- Then you will need to log into your Google account that is associated with this device and restart it. This is done simply: turn it off and synchronize it with your phone again.
- Next, you should receive a message informing you that new updates are available for your gadget. Try to apply them as soon as possible.
"System UI app has stopped" on Samsung Galaxy. What to do?
On some Android devices, particularly the Samsung Galaxy S7 and S7 Edge, the “System UI app has stopped” error may occasionally occur. It appears on the screen in front of the user's eyes. Naturally, the question arises - what is this error and how to fix it?
As for the reasons for this error, it is not yet known exactly why it makes itself felt. There is an opinion that the error may occur if a third-party launcher is installed on the device, if there are problems with the cache and data in certain applications, or if there is a conflict between certain applications.
In any case, the issue must be resolved. Users have already proposed several solutions that should help.
Why do we need an interface?
An interface helps two objects understand each other and exchange information.
An interface is a “language of communication” that is understood by both objects that interact with each other in order to solve a specific issue.
