Xiaomi Redmi camera flicker: 7 reasons and 10 ways to fix

Have you noticed that when you shoot a video or take a photo on a Xiaomi Redmi smartphone, the image begins to flicker like a flashing light? 10/11/12, POCO X3/X4 And other models on the Qualcomm Snapdragon platform or MediaTek, and the flickering can be different, from the slightest jitter of a picture to the brightest bands or the ripple of lighting, and most often the defect occurs when shooting under artificial light (LED-lamps, fluorescent lamps, but sometimes manifests itself in the daytime.

In this article, we will discuss 7 main causes of flickering in the chamber Xiaomi/Redmi — from software failures to hardware features of the matrix, and also give 10 You'll learn how to diagnose the source of the flicker, what camera settings are responsible for stabilizing the image, and when to contact the service center (50/60 Hz is the most common cause that can be fixed manually for 2 minute.

1.Why the camera flickers on Xiaomi Redmi: the main reasons

The flickering in the camera is not always a defect in the device, and in 60 percent of cases, the problem is due to a mismatch between the frequency of the video shooting and the frequency of the flashing of artificial light. LED-The lamp runs at 50 Hz, and the camera shoots video at 30 fps (equivalent to 60 Hz in interlaced scanning), there is a strobe effect:

• 🔹 Frequency conflict is the most common problem when shooting under artificial light (LED, fluorescent lamps).
• 📱 Software failures – errors in the firmware of the camera or MIUI, especially after updates.
• 🔧 Incorrect camera settings - Stabilization enabled, HDR nighttime in inappropriate conditions.
• 💡 Hardware defects – damage to the camera plume, problems with the matrix or autofocus.
• 🔋 Overheating of the processor - during long shooting 4K-Video or use of resource-intensive modes.
• 📱 Application conflict – third-party programs (such as GCam) may not interact properly with the hardware.
• 🔄 Incompatibility of firmware - custom ROM orbeta MIUI sometimes breaks up the camera.

To pinpoint the source of the problem, try shooting videos under different conditions:

1. Turn on the natural light (outdoors during the day), and if there's no flickering, the problem is the frequency of the artificial light.
2. Switch to another shooting mode (for example, from 60 fps to 30 fps).
3. Run the stock camera app (not GCam or other modifications).
4. Check if the smartphone is overheating during the shooting.

Frequency conflict: how to remove flicker when shooting under lamps

If the flickering is only manifested under artificial lighting (LED, Fluorescent lamps, monitor screens, and there's a 95% chance that the problem is that the camera frame rate is not the same as the light source:

• 50 Hz – Europe, Asia, Australia, most of Africa.
• 60 Hz - USA, Canada, Japan, South Korea, part of Latin America.

Xiaomi Redmi camera by default can shoot video at a frequency of 30 fps or 60 fps.

• 30 fps video is actually shot at 60 Hz (interlaced scanning), which conflicts with 50 Hz lamps.
• 60 fps video conflicts with 50 Hz bulbs, but is compatible with 60 Hz.

The solution is simple: change the frequency of the shooting manually.

Open the Camera app

Go to Video Mode

Touch the badge. ⚙️ Settings in the top corner

Select the Permission and Frame Frequency

Install 30 fps (if lamps are at 60 Hz) or 25 fps (if lamps are at 50 Hz)-->

If your region is 50 Hz standard (Russia, Europe), then the optimal settings are:

💡

If the camera settings don’t have 25 fps, use apps like Open Camera or ProCam X, where you can manually set your shooting frequency.

3. Software failures: resetting camera settings and software update

If the flicker appears regardless of the lighting, the problem may be in the software, most often after:

• 📱 Updates MIUI (especially beta).
• 🔄 Installation of custom firmware (LineageOS, Pixel Experience).
• 📸 Use of modified camera applications (GCam, ANX Camera).

The first thing you need to do is reset the camera to the factory settings.

1. Open Settings → Applications → Application Management.
2. Find the Camera app and select Warehouse.
3. Click Clear Data and Clear Cache.
4. Reboot your smartphone.

If the reset didn’t help, check for system updates:

1. Go to Settings → About the phone → System update.
2. If a new version of MIUI is available, install it.
3. After the update, reset the camera settings again.

💡

If the flicker appears after installing GCam, try a different port version (e.g., from the GCam port). BSG or Shamim) or roll back to the stock camera.

For devices with an unlocked bootloader, you can try reflashing the camera module through TWRP. For that:

1. Download the file. camera_module.lib for your model from the forum XDA Developers.
2. Download to TWRP and run the file through Install.
3. Clean Dalvik/ART Cache and reboot.

⚠️ Note: Firmware of the camera module through TWRP This can cause the main or front camera to fail.Before the procedure, make a backup of the partition. /vendor.

4. Hardware problems: when to carry in the service

If the flicker doesn't go away after you change your shooting frequency and reset your settings, you may have hardware problems.

• 🔌 Damage to the camera plume - after falling or disassembling the device.
• 📸 Matrix defects: broken pixels or sensor problems.
• 🔋 Failure of the image stabilizer (OIS/EIS).
• 🔄 Autofocus problems - flickering when refocusing.

Check hardware problems can be as follows:

1. Train test: gently press the back of the smartphone in the camera area, and if the flicker increases, the plume is damaged.
2. Matrix check: shoot the video in total darkness. If you see colored dots or stripes in the image, the matrix is faulty.
3. Diagnostics OIS: set the mode 4K 60 fps and move your smartphone abruptly. If the image floats or flickers, it's a problem with stabilization.

If you suspect a hardware malfunction, do not try to repair the device yourself - this can lead to a complete failure of the camera. Contact the Xiaomi service center or a checked repair center. The average cost of diagnosis is from 500 to 1500 rubles, replacing the plume - from 2000 rubles.
