Xiaomi Mi 9 is a flagship device that combines cutting-edge technology and elegant design. However, as with many modern gadgets, some features can be hidden in the depth of the menu or require activation through additional applications. One such useful option is to use the flash as a light indicator of incoming calls and messages. This is especially true for users who are often in noisy places or carry a phone in a bag where the vibration can not be felt.
In the standard MIUI shell, which is installed on the Xiaomi Mi 9, the process of setting up visual notifications may not seem obvious to a beginner. Developers often change the location of the switches or bring them to individual utilities. In this article, we will discuss in detail all possible ways to activate this feature, from built-in system tools to third-party solutions. You will learn how to adjust the indicator mode, flash frequency and even the color gamut, if the device model allows it.
It is important to understand that the use of LED-While the Xiaomi Mi 9 has a capacious battery installed, the constant operation of the diodes in standby mode can significantly reduce battery life. So before you turn on the function, you should weigh the need for constant use or configure its activation only for important contacts.
Activation through standard MIUI settings
The first and most logical step is to check the built-in capabilities of the system. Android-based MIUI shell provides a wide range of tools for personalization. In newer firmware versions, such as MIUI 11 and MIUI 12, which are available for the Xiaomi Mi 9, the notification settings have been reworked for convenience. You need to go to the main settings menu and find the section responsible for additional system parameters.
Usually, the path to the desired switch is as follows: Settings → Additional → Light indication. However, depending on the firmware version and region, this path can vary. Sometimes the option is hidden in the Special Opportunities or Notification Management section. If you do not find this item right away, search by settings by entering the keyword "flash" or "indicator".
In the menu that opens, you'll see a few switches. We're interested in the option of "Break on a Call" or "Break Out" or "Break Up Notifications" activate the mode you want. It's worth noting that some versions of the software have a "Breakout" feature that flashes when you receive messages from messengers, not just when you make phone calls.
- 🔍 Open the Settings app on the main screen.
- 🔍 Go to the Additional or Special Opportunities section.
- 🔍 Find the Light Indication or Notification Flash.
- 🔍 Activate the switch in front of the desired function.
Once the function is turned on, it is recommended to make a test call to make sure that the smartphone screen does not light up, if the call screen settings are limited, and also remember that if the phone is lying down, the flash will work more efficiently, creating a noticeable light effect.
Use of the application "Call settings"
Owners of Xiaomi devices often find that the standard call interface has its own settings, independent of the general parameters of the system. Xiaomi Mi 9 preinstalled the Phone application, which can be both standard from Google and proprietary development of MIUI Dialer. In both cases, there are hidden menus to expand the functionality.
To access advanced settings, open the Phone app and tap three dots in the corner of the screen (or menu button). Select Settings. In the list that opens, look for Incoming Calls or Call Settings. This is where the switch that blinks the flash during an incoming call often hides, a more direct path than searching in the general Android settings.
⚠️ Note: In some regions (for example, India, China, Indonesia) on the Xiaomi Mi 9 preinstalled dialer MIUI Dialer, which doesn’t have a built-in flash function, in which case you’ll either need to change the region of the phone or install a third-party app, which we’ll talk about below.
If you use Google Phone (blue handset), the path may be different. → Assistant (or Additional) and find the Flash option when notified. In some versions, this feature is called Flash on alerts. LED-call-signaling.
☑️ Checking the call settings
Remember, the changes are effective immediately. However, if you have Do Not Disturb or Silent mode on, the flash may not work because the system thinks you do not want to receive any notifications. Also check if the power saving mode is activated, which can block the background display processes.
Third-party flash management applications
If standard methods have failed to produce results or functionality of your version MIUI It's limited, it's going to come from third-party development from Google Play Market. There are a lot of apps that take over. LED-They often provide more flexible settings, such as blinking color choices, patterns, and even responses to specific applications.
One of the most popular and reliable solutions is the Flash Alerts app or its analogues like LED Flash for Alerts. Once you install such software on the Xiaomi Mi 9, you will need to give it the necessary permissions. The application will work in the background and intercept events about incoming calls, causing the flash to flash according to your settings.
The advantage of third-party webs is that you can customize scripts, for example, you can ask your mom to flash blue and WhatsApp to flash red, which makes a simple indicator a powerful visual communication tool, but you have to be careful with the number of display apps you have installed, because they can conflict with each other.
- 📲 Download Flash Alerts from Play Market.
- 📲 Provide access to contacts and phone when you first start.
- 📲 Enable the Use Camera Flash option in the app settings.
- 📲 Set up a work schedule so you don’t waste your battery at night.
Why can't the app work?
The app will request access to your contacts and call log, which is necessary to determine the incoming number.Make sure you download the program from a trusted developer with a good rating to protect your personal data.
Setup of patterns and modes of operation
For those who want to maximize personalization, advanced settings are available. With third-party software installed on the Xiaomi Mi 9 or some custom firmware, you can adjust not just blinking, but complex light signals, which is especially useful for people with hearing impairments, for whom visual signal is the main way to get information about a call.
In advanced settings, you can adjust the blinking frequency (for example, 2 times per second or 1 time in 3 seconds). You can also adjust the flash duration: short pulse blinking or long burning. Some applications even allow you to synchronize the blinking with the rhythm of the ringtone, creating a light effect.
| Parameter | Description | Impact on the battery |
|---|---|---|
| Frequency of flashing | Speed of LEDs on and off | High frequency increases the flow rate |
| Duration | Burning time of the flash at the event | Long burning consumes a lot of charge |
| Screen mode | Turn on the screen with the flash | Screen switching on – maximum consumption |
| Quiet hours. | Disabling the function at night | Helps to save energy at night |
When setting patterns, be aware that blinking too often can be annoying to others, especially at night in public transport or the cinema, and use Pocket or Quiet Clock mode, which automatically turns off the light indication at a given time or when the phone is in the bag (determined by the light sensor).
💡
Use Quiet Clock mode in the flash settings so that it doesn't blink at night when you sleep, which will keep your battery power and won't wake you up with bright light.
Energy conservation problems and their solution
MIUI is known for its aggressive power optimization, which means that the operating system can force the background processes, including the flash services, to close, and if you set up a feature but it stopped working after a while, that's probably the point.
To solve the problem, add the flash control app (or system service) to the exception list. Go to Settings → Battery → Applications. Find the desired application (for example, "Phone" or "Flash Alert" you installed) in the list. Select Unlimited mode. This will prevent the system from "killing" the process.
⚠️ Note: Setting “No Limits” mode for a large number of applications can lead to a noticeable decrease in battery life of the Xiaomi Mi 9.
Also check if the global power saving mode is on, in this mode the flash brightness can be automatically reduced, or the function can be completely turned off by the system to save charge. If it is critical for you to receive light notifications, keep the energy saving mode off or set its exceptions.
