Setting the brightness of the flashlight on Xiaomi: all ways from MIUI 12 to HyperOS

The flashlight on Xiaomi smartphones has long ceased to be a simple flash — it is a full-fledged tool with adjustable brightness, a strobescope and even color filters in some models. someone for years uses dim light by default, and someone accidentally turns on the mode SOS In this article, we will discuss all ways to adjust the brightness of the flashlight on Xiaomi, including hidden functions. MIUI HyperOS and nuances for different series – from budget Redmi to flagship Xiaomi 14.

It's important to understand that the flashlight's capabilities depend not only on the smartphone model, but also on the firmware version. MIUI 14 appeared a separate section of settings for the flashlight, and in HyperOS (starting with Xiaomi) 13T And then there's the integration with quick gestures, and we tested all the techniques on the actual devices (May 2026 data) and we identified the ones that work consistently. If your smartphone doesn't support some way, it's probably a hardware limitation, not a firmware restriction.

Basic methods of adjusting the brightness of the lamp

On most Xiaomi smartphones, the flashlight brightness changes right while it is running. MIUI 12 and newer, including Poco and Black Shark. Here's how to do it:

1. Turn on the flashlight – swipe down the screen to open the notification bar, and tap the flashlight icon (or use the Xiao voice assistant). AI, I said, "Switch on the flashlight»).
2. Touch the flashlight icon again, and you'll see a brightness slider. Some models, like the Redmi Note, will show up. 12) Icons to hold. 1-2 seconds.
3. Adjust the brightness — move the slider left (dimmer) or right (brighter) — and the changes are applied in real time.

If the slider does not appear, check the firmware version in Settings → The phone. → Version. MIUI. On older versions (below). MIUI 11) brightness adjustment may not be available - update the system or use alternative methods from the following sections.

💡

On some models (e.g. Xiaomi) 12T) The brightness slider only appears when the screen is horizontally oriented. Turn the phone into landscape mode if you can't see the regulator.

The brightness can also be changed through quick settings:

• 🔦 Add the flashlight widget to the main screen: clamp the empty space on the screen → «Widgets» → Find the flashlight and drag it.
• 📱 Use a gesture (on HyperOS): swipe two fingers down the lock screen – this will turn on the flashlight with the last brightness set.
• 🔄 Reset to factory brightness settings: If the flashlight became too dim after the upgrade, go to Settings → Annexes → Application management → Lantern → Warehouse → Clear the data.

The hidden settings of the flashlight in MIUI hyperos

In addition to the basic regulator, Xiaomi firmware has additional options hidden to find them:

1. Open the Settings. → System system → In addition (on MIUI 14 Ways may be different: Settings → Special facilities → Physical buttons).
2. Find the flashlight or flash section (some models call it flash control).
3. Here you'll see:

For example, the regime SOS It's turned on for a long time by pressing the flashlight icon in the notification panel (3 seconds), it turns off the same way - a long press or restart the phone. SOS, If the sensor does not respond, press the power button for 10 seconds for a forced reboot.

Brightness adjustment through the engineering menu (for advanced)

If the standard settings are not satisfactory (for example, the maximum brightness is too weak), you can try to change the parameters through the engineering menu, which is suitable for experienced users and requires caution - incorrect settings can lead to overheating of the flash.

Instructions:

1. Open the Phone app and enter the combination: ##36446337## On some models (Redmi 9, Poco) M3) You may need to code #4636##, then go to Hardware Testing».
2. In the Engineering Menu, select Hardware Testing. → Flashlight (or) LED Testing).
3. Here you'll see the parameters: Max Current, which is the maximum current: 300-500 Ma. Don't zoom in. 700 mA is the risk of overheating! Duty Cycle is the pulse duration (for a strobescope). Flash Mode is the operating mode (constant / blinking).

Set

⚠️ Attention: Increased current above 700 mA can cause the LED flash to burn out. AMOLED-Xiaomi 12, 13 Lite – the brightness of the flashlight is limited by hardware – the engineering menu will not help to increase it.

If after the changes the flashlight began to work unstable (shimmers, spontaneously turns off), reset the settings of the engineering menu:

1. Go back to the Flashlight section.
2. Click Restore Default or enter Max Current = 0, then re-specify the standard (e.g. 500).
3. Reset the device.

Setting brightness through ADB (rootless)

For users who are not afraid of the command line, there is a way to fine-tune the flashlight through the ADB (Android Debug Bridge: This method does not require root rights, but requires a computer and a computer. USB-cable.

What you need:

• 🖥️ Computer with installed Xiaomi drivers (you can download on the official website).
• 📱 Included debugging by USB: Settings → The phone. → Version. MIUI (Tap 7 times to become a developer, then Settings → Additionally. → For developers → Debugging by USB.
• 🔌 Cable USB Type-C (preferably original).

Instructions:

1. Connect the phone to the computer and confirm the debugging permission on the smartphone screen.
2. Open the command prompt (Windows) or terminal (macOS/Linux) and type: adb devices Make sure your device appears in the list.
3. To set the brightness of the flashlight to a maximum (value) 255), Do it with adb shell "echo" 255 > /sys/class/leds/torch-light0/brightness" For average brightness, use the value 128, minimally — 30.
4. To turn off the flashlight: adb shell "echo" 0 > /sys/class/leds/torch-light0/brightness"

These commands are temporary — once the phone is restarted, the brightness will drop. To make the settings permanent, you need to create a script or use applications like Tasker (more about this in the next section).

⚠️ Note: On some models (Redmi Note) 11, Poco X4) The path to the brightness file may be different. If the command doesn't work, try: adb shell "ls" /sys/class/leds/" Find the file that contains flash or torch in the title.

Automation of flashlight brightness with Tasker

Tasker allows you to create automatic scripts for a flashlight, for example, you can configure:

• 🌙 Night mode – the flashlight turns on at 30% brightness after 22:00.
• 🚗 Auto-on when shaking your phone (useful in the car).
• 🔋 Charge savings – brightness decreases to 10% if the battery is below 15%.

Instructions for setting:

1. Install Tasker from Google Play.
2. Create a new task (Tasks) → +) And add the action of Plugin. → AutoTools → Flashlight.
3. In the action settings, specify: Set Brightness - brightness level (from 0 to 255). Toggle - turn on / off the flashlight.

Time → From 22:00 Till 06:00

Save the task and activate it.

For automation by gesture (e.g., shaking):

1. In Tasker, create a new profile (Profiles) → + → Event → Sensor → Shake).
2. Specify sensitivity (e.g., Medium).
3. As an action, select the previously created task with a flashlight.

If Tasker seems complicated, try simpler apps:

• 🔦 Flashlight Widget - a widget with brightness adjustment.
• 🌟 TeslaLED – supports color filters and strobe.
• 🔄 Flash Alerts – flashing flashlights when notified.

Problems with flashlight on Xiaomi and their solutions

Sometimes the flashlight doesn't work properly, doesn't turn on, flickers or spontaneously turns off, and here are the most common problems and ways to fix them:

If none of the methods helped, check the hardware serviceability of the flash:

1. Open the camera and try to take a photo of the flash, and if the flash doesn't work, the problem is in the module.
2. Light the wall with a flashlight at close range, and if the light is dim and reddish, the LED will fail.
3. Connect your phone to the Mi Flash Tool and check the integrity of the persist partition (requires firmware skills).

⚠️ Note: On Xiaomi models with infrared flash (for example, Redmi Note 8 Pro), the flashlight will always be lower than on devices with a conventional LED. This is a hardware limitation, and it is impossible to change it software.

Comparison of flashlight capabilities on different Xiaomi models

Not all Xiaomi smartphones are equally useful in the dark, and we tested flashlights on popular models and compiled a comparison table:

If the brightness of the flashlight is critical for you, pay attention to models with double light. LED-flash (for example, Xiaomi 13 Pro or Redmi) K60 Not only do they shine brighter, they also warm less when they work longer hours.

It is also worth considering that on smartphones with AMOLED-screens (for example, Xiaomi 12 Lite) flashlight can automatically mute when the battery is low – it is laid in the firmware to save energy.

💡

On flagship models (Xiaomi) 13/14, Black Shark: The flashlight supports advanced functions, but it also consumes more energy. For long-term use, it is better to reduce the brightness to 50-70%.
