Flash when calling Xiaomi Redmi 8 Pro: how to turn on and configure

Why Redmi 8 Pro doesn’t flash when you call – and how to fix it

Are you missing important calls because the phone is down screen or in a noisy room? The camera flash on the Xiaomi Redmi 8 Pro can be your savior β€” bright lights will not miss the incoming call. But many users face the problem: the option is simply not in the standard settings. The fact is that the manufacturer hides this feature depending on the regional firmware or the version of MIUI.

In this article, we’ll look at all the ways you can activate a flash, from official settings to hidden commands for the engineering menu, why it might not work even after you turn it on, and how to get around the limitations of MIUI, and what to do if the flash stops flashing after you upgrade, and how to get it back to work without resetting it.

Important: the manual is suitable for Redmi 8 Pro based on MIUI 12, 13 and 14. If you have custom firmware (for example, LineageOS or Pixel Experience), the algorithm may differ, as we will also discuss at the end of the article.

Method 1: Standard MIUI settings (if the option is visible)

On some firmware versions, the flash option is available out of the box when calling.

  1. Open the Settings app (the gear icon on the desktop).
  2. Go to the section Sound and vibration.
  3. Scroll down to the Incoming Calls block and melt Flash when calling.
  4. Activate the switch, it's done!

If you don't have a flash when you call, don't despair. It means your version of MIUI is hiding it. Go to the following ways.

πŸ“Š You’ve already tried to turn on the flash through settings?
Yeah, but there's no option.
Yeah, and it works.
No, I just learned about this function.
I have a different model of Xiaomi.

Why is it missing? Regional restrictions: on firmware in Europe and Russia, the feature is often disabled by default, and it can also be removed after major MIUI updates (for example, when you switch from version 12 to version 13), in which case either a hidden engineering menu or third-party apps will help.

Method 2: Engineering menu (hidden setting)

If there is no standard switch, try activating the flash through the Engineering Menu (CIT) method, which works on 90% of MIUI firmware, but requires caution - do not change other settings so as not to disrupt the phone.

Instructions:

  1. Open the Phone app.
  2. Enter the combination: ##36446337## (this is the code for entering the CIT).
  3. From the menu that opens, select Hardware Testing β†’ Audio β†’ Flashlight.
  4. Find the Flash when ringing setting and set the Enabled value.
  5. Save the settings and restart the phone.

⚠️ Warning: If the phone starts to work unstable after changing the settings (for example, spontaneously restart), go back to the engineering menu and reset the default settings. β†’ The phone. β†’ Resetting settings.

Check the battery (minimum 50%)

Remember current sound and vibration settings

Do not change other parameters in the engineering menu

Reboot your phone after the changes-->

If the engineering menu does not open or gives an error, then your firmware blocks access to CIT, in which case either the MIUI update (sometimes the function returns after an update) or third-party applications will help.

Method 3: Apps from Google Play to control the flash

If the system methods didn't work, installing third-party software might be the solution, and we tested 5 popular apps and selected the two most reliable ones:

  • πŸ”¦ Flash Alerts 2 supports color settings, blinking frequency and works even on a locked screen.
  • πŸ“ž Flash On Call – Simple interface, no ads, but requires permission to access notifications.

How to set up (for example, Flash Alerts 2):

  1. Download the app from Google Play.
  2. Run it and provide all the permissions you have requested (camera, notifications, calls).
  3. Turn on the Flash on Call switch.
  4. In additional settings, select: πŸ”„ Repeat flash - frequency of flashing (recommended) 1-2 momentarily). 🎨 Flash color – flash color (white or color if supported). πŸ”” Vibration – synchronization with vibration.

⚠️ Note: Some applications may conflict with system notifications MIUI. If after installation the phone started to brake, clear the app cache in Settings β†’ Annexes β†’ Application management β†’ [Title of the annex] β†’ Clear the cache.

Flash On CallYes (to MIUI 13)No.Simple interface, low power consumption
Flash Notification 2Partially (may not work on new firmware)There is.Support LED-indicator

Method 4: Configure with ADB (for advanced users)

If you're willing to use the Android debugging bridge (ADB), you can turn on the flash when you call over the command line, which works even on locked firmware, but requires connecting the phone to a PC.

Step-by-step:

  1. Turn on Developer Mode on your phone: Go to Settings β†’ About Phone. Tap 7 times on MIUI Version. Go back to the main settings menu and open Additional β†’ For Developers. Activate Debugging on USB.

Connect your phone to your computer through USB-cable.

ADB Tools

Open the command prompt (Windows) or terminal (macOS/Linux) in the folder with ADB.

adb devices

The name of your device should appear.

adb shell settings put global flash_notification_enabled 1

Reboot the phone.

Important: After the MIUI update, the ADB settings may reset. Repeat the procedure if the flash stops working.

πŸ’‘

Before using ADB, back up your data through Settings β†’ Additional β†’ Backup and Reset. This will help you recover information when you crash.

Why the flash doesn't work even after turning on: 5 reasons and solutions

You've turned on the function, but the flash still doesn't blink? Here are the most common reasons and ways to fix them:

  • πŸ”‹ Low battery charge (less than 15%). MIUI Solution: Charge your phone to 20% or higher.
  • πŸ“± Energy saving mode: Super saving or ultra saving modes block the flash. Solution: disable the mode in Settings β†’ Battery and productivity.
  • πŸ”„ Conflict with other applications. If you have software installed to manage LED-With an indicator (e.g. Light Manager), they can block the flash. Solution: remove conflicting applications.
  • πŸ”§ System settings fail, sometimes after an update MIUI Solution: Reset the camera settings in Settings. β†’ Annexes β†’ Application management β†’ Camera. β†’ Warehouse β†’ Clear the data.
  • πŸ› οΈ Hardware malfunction: If the flash doesn't work even in flashlight mode, the problem may be in the camera module.

If none of these methods worked, check if the feature is disabled at the firmware level. For example, on some versions of MIUI Global for Redmi 8 Pro, the flash is deliberately blocked when calling, in which case only flashing on MIUI EU or Xiaomi.eu will help.

How do you check if the flash is working?
Open the Camera app, go to flashlight mode and turn it on. If the LED doesn't light up, it's hardware. If it's on, look for the reason in the settings or software.

Additional settings: how to make the flash more effective

Turning on the flash is only half the battle, so that it really helps keep your phone off, set it up for you.

  • ⚑ Brightness and frequency. In applications like Flash Alerts. 2 You can choose the intensity of the blinking. For noisy rooms, set the maximum brightness and frequency. 2-3 flash-per-second.
  • 🎡 Synchronization with sound. In settings. MIUI (Sounds and vibrations β†’ Incoming calls) choose a melody with a clear rhythm - the flash will flash in the beat of the music, which will enhance the effect.
  • πŸ”• Contact exceptions: If you don’t want the flash to trigger spam calls, set exceptions in the organizer app (e.g. Truecaller).

Also, pay attention to the time of the flash. By default, it only flashes the first flash. 10-15 - To extend that period:

  1. Install the MacroDroid app from Google Play.
  2. Create a new macro with an Inbound Call trigger.
  3. Add the action Turn on the flashlight.
  4. Set a 30 seconds delay or until the end of the call.

This method will allow the flash to work until you respond or reset the challenge.

Frequent questions about the outbreak on the Redmi 8 Pro

❓ The flash works, but it blinks very dimly?
The brightness of the flash depends on the firmware. You can't change it with the system on the stock MIUI, but you can use applications like Flash Alerts 2, where there's an intensity adjustment, and also check if the cover or the protective glass is covered by an LED, which reduces visibility.
❓ After updating MIUI The flash stopped blinking?
Updates often reset hidden settings. Try: Repeat settings through the engineering menu (method 2). Reinstall the flash control app (method 3). Reset the Sound and Vibration settings to Settings β†’ Apps β†’ App Management β†’ Settings β†’ Storage β†’ Clear the data. If nothing helps, roll back to the previous version of MIUI via Settings β†’ About Phone β†’ System Update β†’ Three Dots β†’ Select the Service Pack.
❓ Can you make the flash flash flash only for certain contacts?
Yes, but not by system means. Install Contact Flash Alert from Google Play. It allows you to: Create white/black contact lists; assign different flash colors to different subscribers; set individual blinking rates; minus: the app consumes an extra battery.
❓ The flash flash flashes, but the phone is getting very hot?
Short-term heating (up to 40-45Β°C) on long calls is normal, because the LED consumes a lot of power. But if the phone heats up to 50Β°C+ or turns off, it's a sign of malfunction. Check: Does the case block the vents. Are there any resource-intensive applications running in the background. Does the flashlight work (if so, the software problem, if not, in the hardware).
❓ Will these methods work on other Xiaomi models?
Yes, most methods are universal for all Xiaomi smartphones on MIUI, including: Redmi Note 8/9/10, POCO X3/F3, Mi 10/11. Exceptions: flagships (such as Xiaomi 13 Pro) may not have an engineering menu, and budget models (such as Redmi A1) may not have a separate LED for flashing.

πŸ’‘

If the flash doesn’t work either way, check the hardware health of the camera module. To do this, turn on flashlight mode – if the LED does not burn, repair is required.
