Xiaomi Mi 9 camera: technical characteristics, capabilities and secrets of professional shooting

The Xiaomi Mi 9, released in 2019, is still one of the brand’s most talked-about smartphones — and thanks in large part to its camera. It was the company’s first flagship with a triple module and a 48-megapixel Sony IMX586 sensor, which has become a benchmark for many subsequent models. But what lies behind these numbers? How does the Mi 9 handle shooting in 2026, and can you squeeze the most out of it without buying a new phone?

In this article, we will not only discuss the specifications of the camera, but also reveal the secrets of its configuration, compare it with modern flagships, and show how to circumvent the limitations of software to obtain professional shots. If you own the Mi 9 or are just planning to buy it, here you will find answers to all questions about its photographic capabilities.

Technical characteristics of the camera Xiaomi Mi 9: what is hidden under the body

The Mi 9 core module is equipped with a Sony IMX586 sensor with a resolution of 48 MP (f/1.75, 1/2, 0.8 μm) — at the time of release it was one of the largest and most sensitive sensors in the mobile segment. However, the real photo resolution is by default 12 MP: the smartphone uses pixel binning technology (combining 4 pixels in 1) to improve light transmission and reduce noise in low light conditions.

Additional modules:

• 📸 12 MP (telephoto, f/2.2, 54 mm, 2x optical zoom – for portrait photography and approximation without loss of quality.
• 🌌 16 MP (super-wide-angle, f/2.2, 117°, 1/3.0") — landscape.

Video is supported in resolution up to 4K@60fps and 1080p@960fps (slow-motion), and there is also HDR10 mode for extended dynamic range. But the most interesting is the software processing: Mi 9 was one of the first to get a night mode with multilayer exposure and AI-optimization of scenes, which automatically adjusts the settings for 27 different types of objects.

Comparison with modern flagships: is the Mi 9 relevant in 2026?

It’s been 5 years since the release, and it’s logical to ask: is the Mi 9 outdated? For an objective comparison, let’s take three key aspects: detail, night shooting and video.

The Mi 9 is less detailed than today’s flagships because of its smaller sensor size and lack of hardware stabilization (OIS) in the main module. However, in daylight, the difference is not critical — especially if you use Pro mode with manual settings. But in night shooting, the gap is obvious: new smartphones use more advanced noise reduction algorithms and long shutter speed with OIS.

Where the Mi 9 still stands is color reproduction and wide-angle photography. Its 16-megapixel ultrawire still gives decent quality, and colors in AI mode often look more natural than some modern devices with aggressive processing.

💡

If you shoot on the Mi 9 in RAW format (via the Pro Mode app), then you can pull out details comparable to the flagships of 2020-2021 when post-processing in Lightroom.

Night Mode: How to Get Maximum Detail in the Dark

Night mode in the Mi 9 works on the principle of multilayer exposure: the smartphone takes several pictures with different shutter speeds and combines them into one. In ideal conditions (complete immobility, tripod), this gives impressive results, but there are nuances:

• 🌙 Exposure time: by default – 2-3 seconds, but in manual mode you can increase to 4 seconds (via camera settings) → Additionally. → Night mode. → Long exposure).
• 📱 Stabilization: without a tripod, enable electronic stabilization in the video settings – this will help blur.
• 🔋 Battery: Night mode puts a lot of stress on the processor. If the charge is below 20%, the camera can automatically turn off long shutter speeds.

For better results:

1. Use a tripod or support (even improvised tools like a stack of books).
2. Turn it off. AI-Optimization in camera settings – it sometimes spoils colors in night mode.
3. Shoot in RAW+JPEG format to adjust the white balance in the editor.

Secret camera settings: how to enable hidden features

MIUI hides a number of useful options that can be activated through an engineering menu or third-party apps, and here are the most useful ones:

⚠️ Warning: Incorrect settings in the engineering menu can cause camera crashes.Do backup data before experiments!

Ways to unlock hidden functions:

• 🔧 Super Night Scene 2.0: Enter ##6484## in the dialer, then select Modem Test → Band Selection → Camera → Night Mode Enhance.
• 📊 Histogram Display: C Camera Settings → Hold your finger on the grid for 5 seconds.
• 🎥 Advanced video settings: Install GCam with support XML-Configs for Mi 9 (e.g., for example, BSG or Urnyx05).

Another life hack is to turn off the video recording restriction. The default Mi 9 stops 4K recording after 10 minutes because of overheating.

1. Install ADB on your PC.
2. Connect the phone and execute the command: adb shell settings put global video_max_duration 0
3. Reset the device.

Best Apps to Shoot on Xiaomi Mi 9

The standard MIUI camera app offers basic features, but to unlock the full potential of the Mi 9, you should pay attention to third-party solutions:

For GCam, we recommend a BSG config with settings:

• 📷 Turn it on. HDR+ Enhanced in the settings.
• 🌃 Activate Astrophotography Mode for night shooting (tripod required).
• 🔄 Turn off Sabre (noise reduction) if you are shooting in RAW.

Important: After installing the GCam, the zoom may not work – this is due to the peculiarities of implementing the telephoto module in the Mi 9. The solution is to use the Camera2 API Probe application to check the support for all modules.

💡

The Mi 9 GCam gives 30-40% better nighttime detail than the standard app, but requires fine tuning. XML-profile.

Typical Mi 9 Camera Problems and How to Fix Them

Despite the advanced hardware, the Mi 9 camera sometimes fails, and here are the most common problems and solutions:

⚠️ Note: If after the update MIUI the camera has started to “lag” or give a green hue in the pictures, try resetting the camera application settings through Settings → Annexes → Camera. → Warehouse → Clear the data.

Flight analysis:

• 🔴 Blurred photos as you approach: The telephoto module in the Mi 9 has a fixed focus.Solution - use digital zoom up to 2x (It uses a main crop sensor).
• 🟢 Green in night mode: Sony sensor problem IMX586. Helps the shutdown. AI or RAW Correction with subsequent correction in Lightroom.
• 🔋 Overheating during video shooting: Limit the resolution to 1080p@60fps or use a cooling case.
• 📵 Camera not focusing: Wipe the lens with a microfiber (often to blame for contamination) or reset the camera settings.

If the problem is not solved software, check the hardware:

1. Run the camera test via ##4636## (Testing → Camera menu).
2. Check if the camera plume is damaged (a common problem after falls).
3. Update your firmware to the latest version of MIUI (new versions fix autofocus bugs).
