FAQ: Frequent questions about flashlight on Xiaomi Redmi 9

Can a flashlight be used as a permanent light source (for example, for reading)?

Technically, but not recommended. The flashlight LED on Redmi 9 is not designed for long-term operation - it overheats and can fail. Maximum continuous use time: 10-15 minutes. For long-term illumination, it is better to use an external flashlight or lamp.

Why does the flashlight turn off after 30 seconds?

This is the standard power saving feature in MIUI. To turn off the timer: Hold the flashlight icon in the notification bar. Press the timer and select Unlimited. On some firmware, this option is hidden. In this case, resetting the notification panel settings (Settings → Notifications → Additional → Reset) will help.

Can you change the color of the flashlight?

On Redmi 9, the color of the LED is fixed rigidly (white with a cold hue of ~6500K). However, with applications like Flashlight + LED, you can simulate color filters by applying a translucent film on the camera, for example, a red filter will help preserve night vision.

The flashlight works, but it's very dim. How do you increase the brightness?

The problem is probably the lens contamination. Gently wipe the glass over the LED with an alcohol napkin. If that doesn't work, check the camera settings: Open the Camera app. Go to Flash mode and turn it on. If the flash is also dim, there's a hardware problem (the LED driver is defective).

Can I use a flashlight under water?

Redmi 9 has no official protection under the standard IP68, So if you're going to get wet, if you don't turn on the flashlight, try: Dry the device in rice or silica gel 24.+ Check the LED contacts after drying (alcohol cleaning may be required). ⚠️ Warning: Do not try to turn on the flashlight immediately after contact with water - this can cause contact corrosion!
