Lighting adjustment on Xiaomi: all ways from MIUI 12 to MIUI 15

The flashlight on Xiaomi smartphones is one of the most popular features, but not all users know that its brightness can be adjusted. By default, most Redmi, POCO and Mi models offer only two modes: weak and bright light. However, additional options are hidden in the depths of MIUI, and new versions of the firmware have expanded settings. In this article, we will analyze all the current ways to change the brightness from standard to engineering menus.

It's important to understand that the adjustment options depend on the smartphone model and the MIUI version. For example, Xiaomi 13/14 flagships support smooth brightness setting, while the budget Redmi Note 10 is limited to fixed levels. We tested all methods on devices with MIUI 12-15 and identified those that work stably. If your flashlight flashes or spontaneously turns off, there is a section at the end of this article that solves this problem.

2. Find the flashlight icon (usually located in the front row or hidden under the swipe to the right).
3. Press and hold the flashlight icon for 1-2 seconds. Some models (POCO F5, Xiaomi 12T) will have a pop-up menu with a choice of brightness level.
4. If retention doesn’t work, tap the icon once to turn on, then again to switch between modes (usually two: “Weak” and “Bright”).

On smartphones with MIUI 14/15 (for example, Xiaomi 13 Lite or Redmi Note 12 Pro+), a slider for smooth adjustment may appear in this menu.

⚠️ Note: On some devices (POCO X3 NFC, Redmi 9A) Long-term retention of the flashlight icon leads to the opening of the Google Assistant settings. In this case, use alternative methods from the following sections.

2. Configure via "Additional settings" of the flashlight

3. Use of gestures and hot keys

Many users don't know that the flashlight can be changed without opening the notification panel, and MIUI uses gestures and button combinations to do this.
