The appearance of an incomprehensible icon at the top of the smartphone screen often causes confusion and anxiety among users. Especially if this symbol is an asterisk, which may indicate various system processes or activated device operating modes. In the operating system Android visual indicators play a key role in informing the owner about the state of the gadget, but sometimes their meaning is not obvious without a detailed analysis.
Before you panic or look for malware, you need to carefully analyze the context of the appearance of this symbol. Most often asterisk on Android indicates that Do Not Disturb mode is turned on, there are unread high-priority notifications, or background applications are running. Understanding the source of the signal will allow you to quickly return the interface to its usual appearance and get rid of unnecessary visual noise.
In this article we will analyze in detail all the possible reasons for the appearance of this indicator on various smartphone models. You will learn how to manage system notification settings, where to look for hidden icons and what steps to take if standard methods of disabling do not work. Proper setup The interface will make using your smartphone more comfortable.
Do not disturb mode: the main reason for the appearance of an asterisk
The most common reason why the asterisk in the status bar lights up is the activation of Do Not Disturb mode. This functionality is designed to block incoming calls, messages and system sounds at a certain time or at the user's request. A visual marker in the form of a star serves as a reminder that the device is in silent mode, and you can miss important calls from contacts not included in the exception list.
To deactivate this mode, simply lower the notification shade by swiping down. In the quick settings panel, you need to find the tile with the name “Do not disturb” or the icon of a crossed out circle/crescent and click on it. If the icon disappears, and the asterisk disappears along with it, then the problem has been solved. In some shells, for example Samsung One UI or Xiaomi MIUI, the icon may look different, but the principle of operation remains unchanged.
It is also worth checking the schedule settings for this mode. Often, users accidentally activate automatic silence at night or on weekends, forgetting about it. To check, go to menu Settings → Sound and vibration → Do not disturb. Here you can disable automatic rules or set exceptions for your favorite contacts.
⚠️ Attention: In some versions of Android, the star may only be displayed if there are missed events in silent mode. Make sure you check your notification history, even if the phone is currently silent.
Management of this mode is critical to the balance between accessibility and personal space. System settings allow you to flexibly configure the behavior of the device, but require careful attention to detail. You should not ignore this functionality, as it helps you concentrate on work or leisure.
System notifications and missed events
Sometimes the asterisk has nothing to do with silent modes, but indicates the presence of unread notifications from system applications. This could be a message indicating that a file download is complete, an app update, or a low battery warning. The operating system thus draws the user's attention to an event that requires his intervention or at least familiarization. Google Play or low battery warning. The operating system thus draws the user's attention to an event that requires his intervention or at least familiarization.
To eliminate the icon, you need to swipe your finger from top to bottom to open the full notification panel. Scroll down to the bottom of the list and look for the Clear All button or cross. If the asterisk remains after cleaning, try rebooting the device. Often the system process responsible for drawing the status bar may freeze, and a simple reboot fixes the visual bug.
Particular attention should be paid to aggregator applications or launchers. If you are using a third-party shell, for example Nova Launcher or Microsoft Launcher, the icon may be generated by the launcher itself as an indicator of new events. In this case, you need to go to the settings of the launcher itself and find the section responsible for “Badges” or “Notification Indicators”.
The table below shows the main types of notifications that can be disguised as an asterisk or accompanied by it:
| Event type | Probability | Check location |
|---|---|---|
| Do not disturb mode | High | Quick settings panel |
| Missed call/SMS | Medium | Call log / Messages |
| System update | Low | Settings → About phone |
| Account synchronization | Medium | Settings → Accounts |
If the star appears only when the screen is unlocked, check the Always On Display settings or themes that can add decorative elements.
Third-party applications and widgets
Do not discount third-party software. Many user-installed applications have permission to display their own icons in the status bar. These could be antiviruses, memory cleaners, instant messengers, or even games. If you recently installed a new application and immediately after that an asterisk appeared, the reason most likely lies there.
To identify the culprit, remember what apps were installed recently. Try temporarily uninstalling the suspect app and see if the icon disappears. It's also worth checking your accessibility settings. Some utilities for controlling brightness or sound use overlays (overlays), which can look like system indicators.
Pay special attention to applications for customizing the interface. Themes, icons, and widgets often add their own decorative elements. If you changed the theme or installed icon packs, try returning the system to the standard style. In the menu Settings → Display → Theme you can reset the changes to factory settings.
⚠️ Attention: Be careful with applications that require wide permissions to work. The asterisk may be a sign of hidden advertising or a miner masquerading as a system process. Check the list of installed apps for names unknown to you.
For diagnostics, you can start your smartphone in Safe Mode. In this state, only system applications are loaded. If the asterisk disappears in safe mode, then the problem is guaranteed to be in third-party software. To enter this mode, you usually need to hold down the power button, and then press the “Power off” item on the screen.
How to enter Safe Mode
Hold the power button. Touch and hold Power Off on the screen. Confirm entering Safe Mode. To exit, simply reboot the device in the usual way.
Features of Samsung, Xiaomi and Huawei shells
Smartphone manufacturers often modify the standard one Android, adding their own unique functions and indicators. Therefore, the behavior of the star may differ depending on the brand of your device. Understanding the specifics of your model will help you find a solution faster.
On devices Samsung with the One UI shell, the asterisk is often associated with the “Missed Call Notifications” feature or the operation of the Samsung Members application. It's also worth checking your accessibility settings, where visual cues for the hearing impaired may be activated. In the menu Settings → Accessibility → Improved hearing you can disable the blinking of the flash or the appearance of icons.
In smartphones Xiaomi (MIUI/HyperOS) an asterisk may indicate activation of the “B” mode pocket" or the work of a second space. Check the settings of the second space in the Settings → Second spacesection. If it is enabled, the indicator can signal the presence of notifications in the second profile.
Devices Huawei and Honor with the EMUI shell often use an asterisk to indicate the importance of a notification in the style of “cards”. It can also be an indicator of energy saving operation. Owners of these devices are recommended to check the “Battery” section and notification settings in the control center.
☑️ Diagnostics by brand
Hidden settings and engineering menu
If standard methods do not help, some hidden function or test mode may be activated. The Android engineering menu allows accessing deep system settings, but requires caution. Accidentally changing parameters in this menu may lead to incorrect operation of the network or display.
One of the reasons may be that USB debugging mode is enabled or interface testing is enabled. Check the section Settings → For Developers. If this section is hidden, it does not need to be activated specifically to resolve the asterisk issue. However, if you have previously enabled it, check the items related to displaying interface elements or overlaying layers.
It is also possible to reset indicator settings via ADB (Android Debug Bridge), but this is a method for advanced users. The command to reset the status bars looks complicated and requires a connection to a computer. For the average user, it is better to limit yourself to resetting the interface settings through the recovery menu or completely resetting the phone if the problem becomes unbearable.
adb shell settings put system status_bar_expanded falseThis command (approximate) can be used to control the state of the status bar, but its use depends on the Android version and access rights. Using ADB commands without a precise understanding of their actions can lead to data loss or unstable system operation. It is better to avoid this method if you are not sure of your actions.
⚠️ Attention: Interfaces and menu names may change with firmware updates. If you do not find an exact match, look for similar items in the settings. Always check the latest instructions for your specific software version on the manufacturer’s official website.
Prevention and optimal interface setup
To avoid the appearance of unnecessary icons in the future, it is recommended to audit installed applications and notification settings. Turn off notifications from apps you rarely use. This will not only remove visual debris, but also save battery power.
Update your operating system and applications regularly. Developers often fix bugs related to incorrect display of icons. Check for updates in the menu Settings → System → Software update.
Use standard themes and launchers if stability is important to you. Customization is a great way to personalize a device, but it often becomes a source of conflict in the system. If you like to experiment, back up your settings before installing new themes.
Systematically checking notification settings and monitoring installed applications is the best way to prevent intrusive indicators from appearing.
Frequently asked questions (FAQ)
Can an asterisk mean a virus?
The asterisk itself is rarely a sign of a virus. However, if it appears after installing a suspicious application from an unknown source, it is worth checking your device with an antivirus. Most often, this is just an interface bug or a silent mode setting.
Why does the asterisk appear only after a reboot?
This may indicate that some application automatically starts when the system starts and immediately creates a notification. Check the startup list in the application settings or use safe mode for diagnostics.
How to remove the asterisk if it does not disappear after resetting the settings?
If even a full reset (Factory Reset) did not help, the problem may be hardware (a defect in the display cable causing artifacts) or related to damage to the system firmware partition. In this case, it is recommended to flash the device or contact a service center.
Does this asterisk affect battery consumption?
The icon itself in the status bar does not consume energy. However, the process that causes it (for example, constantly searching for a network or running a background app) can increase battery consumption. Eliminating the reason for the appearance of the icon often has a positive effect on autonomy.
