Modern smartphones offer many ways to alert incoming events, but in noisy environments or in poor lighting, standard sound or vibration may not be enough. For owners of the Xiaomi Redmi Note 8 T, the issue of visual alert remains relevant, which is guaranteed to attract attention even if the device is lying down. The built-in functionality of the MIUI shell allows you to use the camera LED flash as an indicator of missed calls and messages.
In this article, we will discuss in detail how to activate this feature, what are the restrictions on the Android operating system and how to circumvent standard prohibitions for maximum convenience. You will learn not only about standard tools, but also about proven ways to expand functionality through third-party but secure utilities.
Users often find that after updating the system, settings can be reset or moved to other sections of the menu, which is why it is important to understand the logic of how notifications work in MIUI to quickly find the right switch.
MIUI features for Redmi Note 8 T
The MIUI shell, which is installed on the Redmi Note 8 T, is based on Android, which has strict restrictions on app access to hardware flash in the background, for security and energy saving reasons. However, Xiaomi engineers have left the flash to be used for calls through system accessibility settings.
It should be noted that the standard function works mainly for incoming calls. For messages from messengers or SMS with regular means, it is more difficult to activate flashing of the flashlight, since system restrictions block constant access to the LED for third-party applications.
⚠️ Note: Using a flash as a constant indicator consumes battery life much faster.If you plan to activate this feature, make sure you have the ability to recharge the device during the day.
To activate, you need to go to the special features section. This path may vary slightly depending on the version of MIUI (11, 12 or later), but the general logic is maintained. In newer versions of firmware, the company is striving to unify the menu, so look for sections related to improving hearing or vision.
- 📱 Open the main settings of your smartphone.
- 🔍 Find and go to Advanced Settings or to Additional Features immediately.
- 👁️ Select the item Special Opportunities (sometimes it is placed in a separate menu at the bottom of the list).
- 📞 Find the Hearing tab and activate the Flash switch for notifications.
Once this option is enabled, the phone will flash briefly when an incoming call arrives, which is especially useful when the phone is on the table with the screen down or in the pocket of a transparent case. However, for messages from Viber, Telegram or WhatsApp, this method, alas, will not work without the use of additional tools.
⚠️ Note: Some global firmware versions may have the option of "Notification Flash" hidden or renamed. If you don't find it on the specified path, check for system updates or search for settings by entering the word "flash".

Setting up flash for calls and contacts
When the basic function is activated, it is worth detailing its operation. Redmi Note 8 T allows you to flexibly control how the LED will react. In some versions of the interface, you can adjust the frequency of blinking or the duration of glow, although most often these parameters are rigidly set by the manufacturer to ensure stability.
It's important to understand the difference between system notifications and application-specific notifications, and MIUI's regular setting is primarily tailored to the phone book, which means that if you get a call from a number that isn't saved in your contacts, the flash may not work unless the settings say otherwise.
For maximum effect, check the settings of the Caller itself. Go to the Phone app, click three dots in the corner and select Settings. This sometimes hides additional switches related to visual effects while talking or waiting for a connection.
- 📞 Make sure the flash works for all incoming contacts, not just selected contacts.
- 💡 Check if the "Do Not Disturb" mode conflicts with the indicator.
- 🔋 Note that when the battery is low (less than 15%), the system can force the flash to turn off.
Also worth mentioning is the Pocket Mode feature. If it's activated, the phone may ignore some types of notifications, believing that the device is in a dark enclosed space. If the flash doesn't light up, try temporarily turning off the proximity sensor in the screen settings or special features for inspection.
⚠️ Warning: Prolonged use of flash causes the camera module to heat up.Don't panic if the top of the smartphone body becomes warm after a series of missed calls with an active indicator.

Use of third-party messaging applications
Since the standard functionality of Xiaomi is limited only to calls, to flash a flashlight when receiving SMS or messages from messengers you will have to use third-party software. App stores offer dozens of utilities, but not all of them correctly work with the aggressive policy of energy saving MIUI.
One of the most reliable solutions is the Flash Alerts app, or its analogues, which creates a special service that intercepts notifications and initiates a flash, but in order for this to work consistently, you need to configure permissions correctly.
Right after installation, don't wait for the flash. You need to give the app permission to access notifications and the camera. Without that, the system ban will not allow the utility to control the LED. The setup process may seem complicated, but it is necessary to bypass security restrictions.
- 📥 Download a proven application, such as Flash Alert or Blink Notification from Google Play.
- ⚙️ When you first start, follow the instructions of the setup wizard, providing all the permissions requested.
- 🔋 Go to the battery settings and turn off the power saving for this particular application.
Special attention should be paid to auto-run. On the Redmi Note 8 T, applications are often "unloaded" from memory to save resources. You need to go to the Security app -> Permissions -> Auto-run and turn on the switchboard opposite the installed utility. This ensures that the service will work constantly.

Comparison of Indicator Activation Methods
The choice between regular funds and third-party applications depends on your needs. If you want a flash only for calls, it is better not to overload the system with unnecessary software. If you want total control over all notifications, you need to install additional software.
Below is a table that will help you compare the capabilities of different approaches to adjusting visual signals on the Redmi Note 8 T. It will help you weigh the pros and cons before making changes to the system.
| Parameter | MIUI staff setting | Third-party annexes | Traffic light mode (Accessibility) |
|---|---|---|---|
| Calling jobs | Yeah (stable) | Yes (requires settings) | No. |
| Working with messengers | No. | Yes (Viber, WhatsApp, Telegram) | No. |
| Impact on the battery | Minimum | Medium/High | High (constant survey) |
| Difficulty setting up | Low. | Medium | Tall. |
As you can see from the table, regular funds benefit in stability but lose in functionality. Third-party applications give full control, but require careful adjustment of permissions. Traffic light mode, available in some versions of Android for the visually impaired, on MIUI often works incorrectly or is not available.
Keep in mind that installing unnecessary apps is always a risk. Try to choose utilities with a lot of positive reviews and regular updates. Old, abandoned software may contain security vulnerabilities or work incorrectly with new versions of Android.

💡
Optimal strategy: Use the built-in MIUI feature for calls to save the battery, and only install a third-party app if it is critical to see a flash from instant messengers.

The solution: why the outbreak is not working
Even with the right setup, users can face a situation where the flash stops responding to events, most often the problem lies in updating the system or resetting energy saving parameters. Aggressive optimization is the main enemy of background processes on Xiaomi.
The first thing to do when you have a problem is to restart the device, which is a banal but often effective tip that allows you to reset errors in the camera drivers and notification system, and if the restart didn't work, check if the "Energy Saving" mode is on.
In saving mode, the system turns off all functions, including the LED flash for notifications, and it is also worth checking whether Do Not Disturb or Sleep mode is activated, which can block visual signals. Sometimes it helps to clear the cache of the Settings application or reset special features.
- 🔄 Perform a full smartphone reboot by holding the power button.
- 🔋 Turn off the power saving mode in the notification curtain.
- 🚫 Check the schedule of the mode "Do not disturb" in the sound settings.
If the flash doesn’t work only in certain applications, check their internal settings. For example, WhatsApp or Telegram may have restrictions on notification types. Make sure that the audio signals are turned on for important contacts, since some flashing programs respond specifically to the audible accompaniment of the notification.
