When a Xiaomi, Redmi or POCO smartphone screen suddenly blocks incoming calls and Internet access, it can be taken by surprise at the most inopportune moment. Most often, the cause is an accidental activated flight mode that completely disables all wireless modules of the device. In the interface of the MIUI or HyperOS shell, this function is implemented as simple as possible, but sometimes the system can fail and the usual methods stop working.
Users often experience an airplane icon burning in a status bar, but tapping the icon in the curtain doesn't work. Other times, the problem goes deeper: software conflict, a communication module freeze, or even a physical antenna malfunction. You can turn off the flight mode in a number of ways, from a standard swipe to resetting the network through an engineering menu. It's important to understand what method is suitable in your case, so as not to lose important data.
In this article, we will discuss in detail all possible scenarios for blocking wireless connections on Xiaomi devices, you will learn how to quickly return communication with standard methods, what to do when there are software errors in the interface, and how to diagnose more serious problems with the Wi-Fi module or Bluetooth. Follow the instructions consistently to effectively solve the problem.
Standard ways to disconnect through the notification curtain
The most obvious and quickest method, which works 95% of the time, is using a quick access panel. Xiaomi's MIUI-enclosed smartphones have a convenient wireless interface management system. You need to unlock the screen and swipe from top to bottom of the display. If you use gesture control, you can swipe twice: the first opens notifications, the second opens the control panel.
In the menu that opens, find an icon that shows the plane. If the flight mode is active, it's usually lit in blue or orange, depending on the theme of the design. Task the icon once. The system should emit a characteristic sound, vibration, and the icon in the top status bar will disappear. Immediately after that, the search for the network of the cellular operator will begin.
Sometimes the interface can freeze temporarily. If the first press fails, try swiping up to close the curtain and repeat the action. In some versions of HyperOS firmware, an extended curtain feature is available, where the icons are arranged in two rows. Make sure you click on the right control, not the next function.
- ✈️ Swipe from the top edge of the screen down to open the control center.
- 📶 Find the icon of the plane: if it is colored, the mode is active.
- 👆 Click on the icon once and wait for the icon to disappear in the status bar.
- 🔄 If there is no reaction, close the curtain and try to press again through 5-10 seconds.
Importantly, when you turn this mode on and off, you completely reboot the radio module, which is a useful feature if you lose your 4G network or GPS stops determining location, and forcing flight mode switching often helps you restore the connection faster than waiting for an automatic reconnection.
Disabling flight mode through system settings
If the touch screen is not responding well or the icon is missing, you can always use the classic settings menu, which is the most reliable method, since it addresses directly to system parameters, avoiding possible bugs in the control panel interface. The path to the desired option may vary slightly depending on the version of Android and the MIUI shell.
Open the Settings app on the home screen. At the top of the list, usually just below the search bar or the Mi Account profile, is Flight Mode or Connections and Sharing. In newer versions of HyperOS, the logic may have changed, and the switch is often placed in a separate Network and Internet block.
☑️ Algorithm of actions through settings

Find the switchboard opposite the corresponding item. If it is active (blue or green), click on it to deactivate the function. The system can request confirmation of action if certain restrictions are enabled, but on standard Xiaomi firmware, the switch is instantaneous. Once turned off, the phone will begin to register with the operator's network.
In some cases, especially on custom builds or global versions with Chinese firmware, the menu item may be called differently. Look for sections with the words Network, Connections or Wireless. If you can't find the switch, search by settings: type the word "flight" or "airplane" into the search bar at the top of the settings screen, and the system will indicate the path.
⚠️ Warning: If the flight mode switch is inactive (shadowed in gray) and cannot be pressed in the settings menu, this indicates a serious system failure or damage to the modem drivers. In this case, simple methods will not help, and you will need to restart or reset the settings.
What to do if the button is not working or is frozen
A situation where the interface responds to touch, but the flight mode does not turn off, is quite common on Xiaomi devices. system_server module RIL (Radio Interface Layer, which is the communications center. Before you panic, try a soft reboot of the interface.
The first step is to check the physical power button. On many Redmi and POCO models, pressing the power button for a long time causes the power menu to turn off. If the screen responds but the menu button doesn't work, try pressing and holding the power button for 10-15 seconds before the device is forced to restart, which is the most effective way to reset temporary memory errors.
If the reboot didn’t work, the problem may be in the crowded cache of system applications. Go to Settings → Apps → All apps. Find phone-related apps (often called Phone Services, Sim Toolkit or just Phone) on the list. Go to their properties and select Clear cache. Don’t confuse it with data cleanup, although you can try this one at the very least, but call settings may reset.
- 🔌 Press the power button on 10-15 Seconds for Forced System Restart.
- 🧹 Clear the cache of the phone applications and "SIM-maps" in the settings menu.
- 📱 Check if you have recently installed an application that blocks the network (antiviruses, blockers).
- 🔋 Make sure the battery is above 10%, as at a critical level, the system can lock modules.
