Smartphone owners often face a situation where a missed call or an unread message is discovered too late: loud sound is not always appropriate, and vibration may not be noticed if the device is lying down screen or in a pocket of tight clothing. It is in such cases that the function of light notification comes to the rescue, which attracts the user’s attention by blinking. LED-indicator.
Xiaomi has provided several ways to implement this feature in its MIUI (and new HyperOS) shell, but their location in the settings menu can confuse the inexperienced user. Depending on the firmware version and the specific phone model, the algorithm of actions may differ slightly, but the general principle remains the same for the entire brand ecosystem.
In this article, we will discuss in detail all available methods for activating flash blinks, including standard system tools, hidden engineering menus and third-party applications. You will learn how to configure the indicator for incoming calls, SMS and notifications from instant messengers, and learn how to solve problems if the function stopped working correctly after the update.
Standard settings of MIUI and HyperOS
The first thing a user who wants to activate light signals needs to do is check the basic settings of the system. In most current versions of Xiaomi shells, this option is not hidden deep, but requires careful search. The main path lies through the special features menu, where you can find features that facilitate interaction with the device.
To activate the function, you need to go to Settings, then select the optional settings and find the special features subsection there. In the list that opens, you should pay attention to the Visual or Hearing tab, where the desired switch is located, and this is where the LED display for system events is controlled.
⚠️ Attention: Some global firmware versions may have different paths. If you don't find a paragraph in the "Additional Settings", try typing the word "flash" or "blink" in the settings search bar - the system will redirect you to the desired section.
It’s important to understand that standard settings are often limited to blinking when an incoming call is made. Notifications from apps in this mode may not activate the camera, which is a limitation of the Android system itself, not a defect of the phone. Extended functionality will require the use of additional tools, which will be discussed below.
Use of the Camera app for notifications
The feature built directly into Xiaomi’s standard Camera app is often more stable and energy efficient, as it doesn’t require third-party software. The logic is simple: it uses the hardware flash of the main module to signal events.
To set up this mode, open the Camera app and go to the settings menu called by pressing three horizontal bars or a gear in the corner of the screen. In the list of parameters, you need to find the item "Flash for notifications" or "Flash at notifications." Activation of this switch will cause the camera to light up briefly when new messages arrive.
- 📸 Mode: Flash flashes once or more times when notified, even if the screen is off.
- 🔋 Energy consumption: Short-term pulses of the LED have little to no effect on battery charge.
- ⚙️ Compatibility: The feature runs in the background and does not require the camera app to be opened constantly.
There is an important nuance: on some Xiaomi smartphones, this feature in the Camera app can only work when the device’s screen is unlocked or in sleep mode, but not completely off.
💡
If the camera’s standard setting doesn’t work in screen lock mode, try setting the Pin Code or pattern lock lock type – on some versions of MIUI this will activate the system’s deeper event monitoring.
Configuring through third-party applications
In cases where the built-in capabilities of the system are not enough, or the phone model does not support native blinking at notifications, specialized applications from the Google Play store come to the rescue. They allow you to flexibly adjust blinking patterns, colors (if used). RGB-indicator) and reference to specific contacts.
One of the most popular and proven solutions is the Flash Alerts app or its analogues. Once installed, the program will request permission to use the camera and access notifications. granting these permissions is critical for the app to function correctly. In the application interface, you can choose which events the flash should trigger: calls, SMS, messages from WhatsApp, Telegram or Viber.
The advantage of third-party solutions is that you can fine-tune the number of flashes, the duration of the glow, and even create unique profiles for different contacts, for example, for important calls, the phone can blink quickly and often, and for spam, it can rarely and singlely.
Security of Third Party Applications
However, using third-party software has a downside: applications run in the background and can consume more power than system counterparts, and the aggressive battery saving policy in MIUI can kill the application process, causing the flash to stop burning until you reopen the program.
Solving problems with the outbreak
Even when set up correctly, users may find themselves in a situation where the flash stops blinking, most often the problem lies in the power saving system that is characteristic of Xiaomi devices. The operating system can limit the background activity of processes, considering them excessive to save charge.
To fix this problem, go to the battery settings. Find the one in the application list that is responsible for the flash (this can be Camera, Phone, or a third-party application installed), go to its settings and select No Limits or No Limits mode, which will prevent the system from forcibly shutting down the process.
It's also worth checking for conflicts with other features, such as Do Not Disturb or Sleep Mode, which can block visual notifications, and make sure that these modes don't tick off all the indicators.
☑️ Diagnostics of a faulty outbreak
If the flash doesn't work even in the Camera app when you're shooting, the problem may be hardware, and then the software settings won't help, and you'll need a diagnostic at the service center, but if the flashlight lights up but doesn't blink when you call, it's just the software.
Comparison of activation methods
To make it easier for the user to choose the best way, we have prepared a comparison table that will help determine which method best suits your specific needs and device model.
| Method | Stability of work | Impact on the battery | Flexibility of settings |
|---|---|---|---|
| System settings (Special Opportunities) | Tall. | Minimum | Low (calls only) |
| Annex "Camera" | Medium/High | Minimum | Medium (notifications) |
| Third-party annexes | Depends on the OS. | Average. | Maximum |
As you can see from the table, the best way to do basic things is to have built-in tools that are integrated at a deep level and rarely fail, and third-party solutions that you can only consider if you want to have a complex logic, like flashing different colors for different contacts.
💡
The best choice for most users is a combination of system settings and features in the Camera app, as this provides a balance between functionality and autonomy of the device.
