How to set up a camera on Xiaomi Mi 6: from basic parameters to professional modes

The Xiaomi Mi 6 is still a cult smartphone for amateur photographers, despite its release in 2017. Its dual camera with 12 MP + 12 MP sensors (wide-angle and telephoto) is capable of delivering impressive images, provided you set it up correctly. However, many users still do not use even half of the camera’s capabilities due to the confusing interface or lack of manuals relevant to modern firmware versions.

In this article, we'll look at not only basic settings, but also hidden features that the manufacturer doesn't advertise, how to turn on Pro mode for manual exposure settings, how to calibrate autofocus for macro photography, and why forced HDR shutdown in some scenes gives you more natural colors, and how to bypass the limitations of a standard camera app with alternative firmware and mods.

Preparation for configuration: checking the software version and cleaning the cache

Before you get into fine-tuning the camera, make sure your Mi 6 runs on the current firmware version. MIUI (below MIUI 12.5) may not support modern image processing algorithms, such as: AI-Scene optimization or improved night mode to check version:

1. Open the settings → About the phone → version of MIUI.
2. Compare the build number with the latest stable versions on Xiaomi’s official website.
3. If the version is outdated, update via Settings → System Update.

It is also recommended to clear the cache of the camera application, since accumulated temporary files can affect the performance and correctness of the algorithms.

Settings → Applications → Application Management → Camera → Storage → Clear the cache

If the camera is unstable after the update (for example, it focuses for a long time or gives a green hue on the photo), try resetting it to the factory settings: ⚙️ → Restore the default settings.

⚠️ Note: Some custom firmware (e.g. LineageOS 20) may not support dual zoom on a standard camera app, requiring the installation of alternative software such as GCam or GCam. FOSS Camera.

Basic camera settings: what to turn on right away

The standard camera app on the Mi 6 offers many options, but most of them are hidden behind non-obvious menus.

• 📸 Photo resolution: Select the maximum (12 MP 4:3) for the best quality. 16:9 format cuts the edges of the picture without adding details.
• 🌙 Night mode: Turn on AI-night mode in settings, but disable automatic application - it often works during the day in rooms with dim light, spoiling the colors.
• 🔄 HDR: The default is the Auto.-HDR, But for static scenes, it is better to use them. HDR Always, and for dynamic ones, shut down completely.
• 🎯 Focus: Turn on Continuous Autofocus (CAF) to shoot video, but turn it off for macro - otherwise the camera will constantly "breathe".

You pay special attention to adjusting the white balance. In the Mi 6, it often overstates the temperature, giving the pictures a yellow appearance.

1. Go to Pro Mode (Professional).
2. Touch the WB (White Balance) icon.
3. Select the 4500-5000K value for daylight instead of the automatic mode.

Set the 12 MP resolution (4:3)|Disable Xiaomi watermarks|Insert retention RAW (if necessary)|Set up white balance manually|Turn off the shutter sound (if annoying)-->

Remember the serial shooter, which is surprisingly fast in the Mi 6 (up to 10 frames per second), and to activate it, hold the shutter button or turn on the Quick Shooting mode in the side menu.

Professional Mode: Manual setting for the perfect shot

The Pro mode in the Mi 6 camera allows you to manually control all the key parameters of shooting: shutter speed, ISO, focus and white balance, which is especially useful in difficult lighting conditions or for creative photography.

For shooting the starry sky or glowing trails, use 10 to 30 seconds shutter speed and ISO 1600. However, note that the Mi 6 does not have a mechanical shutter, so artifacts are possible at long shutter speeds due to overheating of the sensor, to minimize them:

• 🌡️ Allow the camera to cool down before shooting (5-10 minutes in standby mode).
• 🔋 Charge the battery to 100% – at low charge, the smartphone limits performance.
• 📱 Use external cooling (such as a small fan).

If you need to take a portrait with a blurred background (boke), use a second lens (telephoto) and approach the object at a distance of 50–100 cm. Manually set the aperture on F/2.6 (maximum blur) and focus on the model's eyes. Avoid shooting against the background of monochromatic walls - the segmentation algorithm can "cut" hair or ears.

Video Customization: 4K, Stabilization and Sound

Xiaomi Mi 6 supports video shooting in 4K resolution (3840×2160) at 30 fps, and Full HD (1080p) at 60 fps. However, by default, the camera shoots at 1080p/30fps - a compromise between quality and file size.

Open the camera → Switch to video mode → Touch the icons ⚙️ → Resolution → 4K

For stable video, turn on Electronic Stabilization (EIS), but note that it trims the edges of the frame by ~10%.If you need the maximum field of view (for example, for vlog), turn off stabilization and use an external stabilizer or Gimbal.

• 🎥 Bitrate video: In 4K he composes ~48 Mbps, at Full HD — ~20 Mbps. for installation it is better to shoot in 4K, Even if the final video is in full. HD.
• 🔊 Sound: The Mi 6 microphone records stereo but does not suppress noise well. Use an external microphone (e.g. Boya) for clean sound BY-M1).
• 🔄 Autofocus: It works slower in video than in photos. For dynamic scenes (sports, animals) switch to video mode. CAF (continuous autofocus).

If the video is soapy in poor light, try lowering the resolution to 1080p and increasing the bitrate through the engineering menu (available on custom firmware). Also avoid digital zoom - better come closer or use a second lens (2× optical zoom).

💡

To shoot slow-motion video, switch to Slow-Speed mode and select 120 fps (720p) or 240 fps (480p). To avoid "twitching" the frame, shoot in bright light (suspension should be shorter than 1/240).

Hidden functions and engineering menu

The Xiaomi Mi 6 has hidden camera settings that don't show up in the standard interface. To activate them, you need to use an engineering menu or special codes. Careful: the wrong changes can lead to crashes!

To access the camera's engineering menu:

1. Open the Phone app.
2. Enter the code ##4636##
3. Go to the Camera Information tab.

Here you can:

• 📊 View detailed information about sensors (Sony models) IMX386 and IMX378).
• 🔧 Enable debugging modes such as Raw Capture (save raw data from the sensor).
• 🔄 Change the noise reduction and sharpening algorithms (Denoise and Sharpening parameters).

For power users, AF calibration is also available, and if your camera doesn’t focus well on close objects, follow these steps:

1. In the engineering menu, select AF Calibration.


2. Place the phone at a distance of 20 cm from the text sheet (font ~12 pt).




3.Push Start Calibration and wait until completion (~30 seconds).




4. Reset the device.

⚠️ Note: Do not change the Lens Shading and Awb Calibration settings without understanding the consequences. Incorrect values can lead to a constant green or purple hue in all photos that cannot be fixed software.

💡

The engineering menu allows you to fine-tune the camera for specific tasks, but all changes should be fixed (record the initial values) and tested on several scenes before constant use.

Alternative Camera Apps: GCam and Others

Xiaomi’s standard camera app has limitations, especially in handling HDR and night scenes. Many users install the Google Camera (GCam), a modified version of the Pixel camera that works better with Sony’s IMX sensors.

The following versions of the GCam are suitable for the Mi 6:

• 📷 BSG GCam (v8.1) — Stable operation with both sensors.
• 📷 Urnyx05 GCam (v7.3) — Best Portrait Mode Processing.
• 📷 Nikita GCam – Optimized for weak processors (but can slow down on the processor) 4K video).

To install the GCam:

1. Download APK from a trusted source (e.g. Celso Azevedo).
2. Allow installation from unknown sources in the security settings.
3. After installation, open GCam and import the config for Mi 6 (.xml file).

The advantages of the GCam on the Mi 6:

However, GCam has its disadvantages:

• ⚠️ No support for a second lens (telephoto) in some assemblies.
• ⚠️ Video in the video 4K can be recorded with artifacts.
• ⚠️ Zoom works only digitally (without optical approximation).

If GCam doesn’t fit, try FOSS Camera (open source) or Open Camera – they support manual ISO and shutter speed settings, as well as saving to RAW.

Frequent problems and their solutions

Even when properly set up, the Mi 6 can be unstable, and here are some of the most common problems and ways to fix them:

• 🔴 Camera won't open: Restart your phone. Clear the cache and the camera app data. Check if the antivirus or security is blocking access. MIUI.
• 🟢 Green in the photo: Turn it off AI-Optimize your camera settings. Manually set white balance to 5000K. Update the firmware – in the old versions there was a bug with flower processing.
• 📸 Blurred pictures with macro: Use manual focus (MF) In Pro mode. Turn it off. HDR — It's a short-range, sharpening device. Check the lens' cleanliness (dust and fingerprints are very important for macros).

If the camera started to "glue" after the MIUI update, try rolling back on the previous firmware version or installing a custom restore (such as TWRP) and flashing the camera module separately. There are current patches for the Mi 6 on the 4PDA and XDA Developers forums.

⚠️ Note: If the camera stopped working completely after firmware (Cannot connect to camera error), the persist.camera file is most likely damaged.In this case, only a complete reset will help (Wipe Data in the Internet). TWRP).
