How to turn on the flashlight on Xiaomi Mi 9T: all ways + problem solving

Xiaomi Mi 9T is one of the most popular smartphones of the brand, which is still actively used thanks to the powerful hardware and up-to-date firmware. But even experienced users sometimes have questions about basic functions - for example, how to quickly turn on the flashlight in a critical situation. In this article, we will analyze all possible ways to activate the flashlight on the Mi 9T, including hidden MIUI chips, and also solve typical problems when the LED refuses to work.

The flashlight on the Xiaomi Mi 9T is implemented through a dual LED with a temperature of 4000K and a brightness of up to 20 lumens – enough to illuminate the key in the lock or find a fallen object in the dark. However, not everyone knows that the setting of this feature is flexible: it can be tied to gestures, voice commands or even a lock button. Next, a detailed guide with illustrations (in text format) and life hacks for different versions of MIUI.

1. Standard method: through the notification panel

The most obvious and universal method is to use a notification curtain, which works on all versions of MIUI (from 10 to 14) and does not require additional settings.

1. Unlock the Mi 9T screen (fingerprint, pattern lock or PIN is appropriate).
2. Swipe down from the top edge of the screen to open the notification bar.
3. If the panel is not fully opened, make a second swipe down - so all the icons will appear.
4. Find the flashlight icon (🔦) and tap her once.

The LED will turn on instantly and the icon will be lit in yellow, which means that the flashlight is active. To turn off, re-press the icon. Importantly, if the flashlight icon is not in the curtain, you need to add it manually (more about this in the next section).

💡

On the Mi 9T with MIUI 12+, you can set the flashlight to automatically turn on when shaking your phone. Go to Settings → Special Features → Gestures → Shake for the flashlight

2. Adding flashlight icon to notification curtain

If the flashlight icon is not in the quick access panel, it's easy to add it. MIUI:

1. Open the notification curtain (swipe down from the top edge).
2. Slap the icon «⚙️» (Edit or hold your finger on the empty panel space.
3. In the list of available tiles, find the "Lightlight» (🔦) and drag him to the active area.
4. Click “Ready” or “✓” to save the changes.

Now the icon will always be at hand. Please note: on some custom firmware (for example, Pixel Experience), the path may be different - there the flashlight is added through Settings → System → Notification Panel.

Make sure your smartphone is unlocked

3. Enabling the flashlight with the lock button (hidden function)

Few people know, but on the Xiaomi Mi 9T, you can turn on the flashlight with a double press of the lock button - even when the screen is off! This feature is hidden in the settings and works on MIUI 11 and later.

1. Go to Settings → Screen Lock and Password.
2. Select the option "Double pressing the power button".
3. In the action list, find the “Lightlight” and tick.
4. Save the changes.

Now, to turn on the flashlight, you just need to press the lock button twice quickly (even in your pocket or with the screen off), which consumes minimal battery power, since it only activates the LED, not the entire screen. However, note that in Do Not Disturb or at a discharge below 5%, it may not work.

4. Voice flashlight control (Alice and Google Assistant)

If you have a voice assistant set up, you can turn on the flashlight with your voice -- it's convenient when your hands are busy. It works with both Alice (from Yandex) and Google Assistant. Here are commands that the assistants understand:

• 🎤 «Okay, Google, turn on the flashlight»
• 🎤 «Alice, light up»
• 🎤 «Hey, Google, turn on the flashlight)
• 🎤 «Alice, turn on the flashlight as much as possible»

For the function to work, make sure that:

• 📱 Voice Assistant has access to Camera and Lantern (check in app settings).
• 🔊 The microphone is not silenced (for example, after falling or getting moisture).
• 🌐 Internet access (for processing voice commands on Yandex servers)/Google).

An important caveat: on some firmware, voice-activated flashlights only work when the screen is unlocked. If the command doesn't work, try unlocking the phone first.

5. Gestures and additional ways of inclusion

MIUI offers some non-obvious flashlight controls that you can customize to your needs.

Warning: The shaking gesture may be triggered by accident (e.g. while running or cycling) If it interferes, turn it off or increase sensitivity in settings.

⚠️ Attention: On Mi 9T With custom firmware (like LineageOS), gestures and voice commands may not work, in which case use the standard method through the curtain or install a third-party application like Flashlight Widget.
