Xiaomi smartphones are well-deservedly popular due to their wide functionality and affordable price, but the MIUI shell sometimes hides the settings that users would like to change. One of these features is the activation of the flash during an incoming call. On the Redmi Note 7 model, this feature can be activated by default or turned on accidentally, which causes discomfort in the dark or in the theater.
Many owners face a situation where when a call comes, the phone not only rings and vibrates, but also begins to actively flash the LED. This not only consumes battery power, but can also attract unnecessary attention. In this article, we will discuss in detail all the available ways to deactivate this option, including standard menus and hidden engineering codes.
The setup process does not require super-user permissions and is safe for your device, and we will look at the standard methods provided by the developers of MIUI, and also discuss possible reasons why the setup may not be saved after a reboot.
Why do you need a flash when calling and whether it is worth turning it off?
The notification flash feature was introduced by developers to increase the visibility of incoming events. In a noisy room or when the phone is lying down, a flashing light helps the user respond to the call faster. However, in the context of the Redmi Note 7 model, using the main camera as an indicator has its drawbacks.
First, the constant blinking greatly speeds up battery discharge. Second, it can be annoying if you are in a quiet place. If you rarely miss calls and prefer a vibration signal or a tune, turning off this feature will be a logical step to optimize the performance of your gadget.
It is worth noting that in some versions of the firmware, this option may conflict with other system notifications, for example, the flash may start to flash not only when a call is made, but also when messages are received in messengers, if the system has the appropriate priority.
⚠️ Attention: Long-term operation of the LED flash in the enclosed space of the housing can lead to local heating of the camera module, which theoretically affects the resource of the component.
Standard way to disconnect through call settings
The easiest and safest way to manage a call indicator is in the standard phone book menu. MIUI often hides the options in the submenu, so it's important to follow the sequence carefully, which is relevant for most of the firmware versions installed on the Redmi Note 7.
To start, open the Phone app (green handset) and go to call settings. Here you need to find the incoming call section. Depending on the shell version, the item may be called Incoming Calls or Call Settings. This is where the LED switch is hiding.
If you don't see the right item right away, check if you have Do Not Disturb or Quiet Mode on, as in some configurations, the indicator settings may be blocked by these profiles. Once you find the switch, just put it in an inactive state.
- 📱 Open the phone application on the desktop.
- ⚙️ Click on the three dots in the corner of the screen or the menu button to enter the settings.
- 🔔 Select Incoming Calls in the Options List.
- 💡 Find the Flash line when calling and turn it off.
⚠️ Note: Some global firmware versions may have different customization paths than the Chinese version, so look for similar menu items.
After these steps are completed, the system should stop activating the LED when the signal arrives. If the changes do not take effect immediately, try making a test call from another number or restart the device.
Configure through the system application "Camera"
In rare cases, the control of the light indicator can be duplicated in the settings of the camera module itself. Since the function uses a physical flash, it is logical to assume that Xiaomi could leave access to control it in the corresponding application, this is especially true for older versions of MIUI installed on the Redmi Note 7.
Go to the Camera app and open the settings menu (usually the three horizontal bars in the upper right corner). Scroll down to the option section "Additional" or "System settings." There may be a paragraph associated with using the flash for notifications.
It is also worth checking the availability settings. in the section "Advanced settings» → «Special features" sometimes come up with the "Flash for notifications" option, which works globally for the entire system, including calls.
What to do if the settings are reset?
Using the Engineering Menu for Diagnostics
If standard methods don't work, you can go to a deeper level of customization, the engineering menu, which is designed to test hardware components and check if the problem is software or hardware. The Redmi Note 7 has a standard MIUI codeset available.
Type in dialer code ##6484## to enter CIT mode, where you can test the flash separately from the call, select the LED or Flash item and check it. If the flash doesn't light up even in test mode, the problem may be in the hardware.
In some versions of firmware, you can reset the radio module settings through the engineering menu, which sometimes helps if the glitch is associated with processing the network signal. However, be careful: changing unknown parameters in this menu can lead to work disruptions of the smartphone.
- 🔢 Type ##6484## in the call app.
- 🧪 Choose the Flashlight test or LED list.
- 👁️ Check if the indicator lights up when pressed.
- 🔄 If necessary, reset the test parameters.
Third-party applications for managing notifications
When built-in tools are scarce, third-party solutions come to the rescue from the Google Play store. There are many call dealer apps and notification managers that take precedence over Android system settings, allowing you to flexibly customize the flashlight behavior for different contacts.
One popular solution is to use apps to replace the standard "caller," and once you install this software, you have complete control over how the phone behaves when you call, you can ask the rule, "If it's 23:00 to 7:00, don't flash."
There are also specialized utilities, such as Flash Alerts, that intercept the call signal, and you can completely disable the use of the camera for display in their settings, which is a reliable way if the MIUI system bug does not disable the function by regular means.
Table: Comparison of disconnection methods
To make it easier for you to choose the right way, we have organized the information in a table that will help you quickly assess the effectiveness of each method for your specific situation with the Redmi Note 7.
| Method | Difficulty | Efficiency | Risks. |
|---|---|---|---|
| Call settings | Low. | Tall. | Absent. |
| Accessibility settings | Medium | Medium | Disabling other notifications |
| Engineering menu | Tall. | Diagnostic | System failure in case of error |
| Third-party software | Low. | Tall. | Battery consumption by application |
Possible problems and solutions
Even after completing all the instructions, users may find the flashlight blinking, often because the Pocket or Pocket mode is activated, which uses a proximity sensor and flash to signal missed events if the phone was locked.
Another common reason is third-party themes, and some MIUI themes have their own call animation settings that ignore system bans. Try switching to the standard Classic theme and checking the indicator behavior.
If nothing helps, it may be a specific messenger app (Viber, WhatsApp, Telegram) that uses its own flash to notify you of an incoming VoIP call, so you should look for the settings inside the messenger app itself in the Notifications section.
⚠️ Attention: Installing a large number of topics from unofficial sources can lead to conflicts in the system and incorrect operation of hardware modules.
