How to Incorporate Dual Camera on Xiaomi: The Complete Guide

Many Xiaomi smartphone users are puzzled when they can’t find a button to switch to a wide-angle lens or a bokeh portrait mode. Often the reason lies not in the device breakdown, but in the features of the MIUI or HyperOS shell interface, where optics control is hidden behind additional menus. Understanding the logic of the standard Camera application allows you to unlock the full potential of photography, laid down by the company’s engineers.

In modern Redmi and POCO models, the number of modules can be as high as three or four, but the activation of each one depends on the scenario chosen. Some modes, such as macro or telephoto lens, are only turned on under certain lighting conditions or approaching an object. Automatic switching between lenses is a standard feature, but manual control often gives a more predictable result.

In this article, we will discuss in detail how to force the second module to activate, adjust depth of field, and what to do if the wide-angle camera no longer appears in the interface, learn how to manage focal length and use professional settings to obtain studio-quality shots.

The principle of operation of additional modules in MIUI

Xiaomi smartphones are equipped with a set of sensors, each of which solves problems: the main module is responsible for detailing, the ultra-wide-angle captures more space, and the macro camera allows you to take pictures of small objects close. Switching between them either automatically when artificial intelligence algorithms determine the scene, or manually through the viewfinder interface. Physical switching of the optics is software, so it is important that the software works correctly.

Users often confuse digital zoom with optical zoom. When you spread your fingers across the screen, zoom in on the image, you often use the crop of the main sensor, which reduces quality. However, when you reach certain values, such as 0.6x or 2x, the system can switch to the corresponding lens. Xiaomi implements this through special points on the zoom scale, which are highlighted when a particular module is activated.

⚠️ Note: If, when switching to 0.6x or 2x The image does not change dramatically, and continues smooth zoom, so this model uses virtual switching or the second module has a low resolution and is activated only in the indirect modes.

Manual control often requires you to switch to “More” mode or use the side settings menu, which hides the switches for macro, ultra-wide angle and sometimes telephoto lens. It is important to understand that the inclusion of an additional camera can be limited software in video mode or when shooting at high resolution 108 MP and above.

Activation of wide-angle lens (0.6x)

The most popular second module is the ultra-wide-angle camera, and to turn it on, you can run the Camera app and look at the bottom of the screen where the zoom scale is located. Usually there's a button that's 0.6 or 0.5, and clicking on it instantly switches the viewfinder to a wide-angle lens, which allows you to capture more objects in the frame, for example, when shooting architecture or group photos.

If the 0.6x button is not on the home screen, check the side menu or swipe to the right of the shutter button. In some versions of MIUI firmware, the switch may be hidden in the drop-down mode list. It is also worth remembering that when this mode is turned on, the focal length changes, and distortions at the edges of the frame become more noticeable.

• 📸 Click on the 0.6 icon on the zoom scale for instant switching.
• 📐 Use a tripod, as wide-angle lenses often have less aperture and require longer shutter speeds.
• 🌄 Perfect for landscapes and interiors where you need to show the scale of space.

The quality of the shots on the "width" usually inferior to the main module, especially in underlight. Noise reduction algorithms are more aggressive, and dynamic range may be narrower. Therefore, for night shooting, it is better not to use wide-angle mode unless your model has a separate night optimization for this sensor.

💡

For the best 0.6x landscape shots, try to hold your phone strictly horizontally. The camera's tilt up or down can cause severe geometric distortions of the vertical lines of buildings.

Using Portrait Mode for Bokeh Effect

Portrait Mode is a software simulation of a dual camera, where one lens builds a depth map and the second (or main) takes a picture. To turn on this mode, select the corresponding icon in the bottom menu or find it in the "More" section, where you can adjust the degree of background blur, simulating the change in the aperture.

In portrait mode settings, Studio Lighting is often available, which adds light effects to the face of an object. The camera analyzes the distance to the object and background objects, creating an optical blur effect. To work correctly, the object must be located at a distance of 0.5 to 2 meters from the lens.

It's worth noting that in the dark, portrait mode may not turn on or work with errors, because the system lacks contrast to build a depth map. If you see a message "Move further" or "Come closer," change the distance. Artificial intelligence in new models Xiaomi has learned to determine the boundaries of objects even without a second telephoto lens, using only the main sensor.

Macro lens setup and ultra-close shooting

The macro lens in Xiaomi smartphones is often a separate module with a fixed focus. To activate it, you don't need to look for a separate Macro button in the main interface. Just hold the phone to the object at a distance of 2-4 centimeters, the system itself recognizes the scene and switches to macro mode, as reported by a pop-up notification or flower icon.

In some cases, the automation fails, and then you manually select the Macro mode from the More menu, which forces the second or third camera module, which has a very short focal length, and the resolution of these images is usually lower than the main camera, often as low as 2 or 5 MP.

• 🔍 Hold the camera close to the subject (2-3 cm) for auto-activation.
• 🌿 Use macro mode to capture textures, insects, jewelry.
• 💡 Provide bright lighting as the phone blocks the light at a minimum distance.

It's important to keep your hands as still as possible, because depth of field in macro mode is measured in millimeters. Any jitter will lead to lubrication. Stabilization of the image in budget models on macro lenses is often absent, so using a stop or a tripod is critical for sharp shots.

Switching problems and their solution

There are situations where the second camera module simply doesn't turn on, the viewfinder stays black, or an error message appears, which can be caused by a software failure or physical damage to the plume. The first step should always be software diagnostics, since hardware malfunctions are less common than software conflicts.

Try clearing the Camera app cache. To do this, go to Settings → Apps → All apps, find Camera, select Memory and click Clear Cache. This action will not delete your photos, but reset the app settings to factory settings, which often solves the problem of switches hanging.

⚠️ Warning: If after resetting the camera settings and restarting the phone, the second module still does not work (black screen when switching) 0.6x Or macro, there's a high probability of plume failure or sensor failure.

It can also be a problem with third-party apps, such as if you use Google or Open Camera cameras, make sure they have all the permissions they need, and in rare cases, updating the firmware to the latest version helps, as Xiaomi regularly releases patches that improve image processing algorithms.

Third-party applications for camera control

If the standard app doesn’t give you the control you need, you can use third-party solutions like Google Camera (GCam) or Open Camera. These apps allow you to manually select an active sensor if the device supports the Camera2 API. In GCam settings, you can often find the option “Auxiliary camera” that you need to activate.

To enable manual sensor selection in advanced cameras, commands may be required through ADB or the use of special configuration files, which gives access to RAW-format from all modules and allows you to adjust the shutter speed and ISO However, the stability of third-party software is not guaranteed on all models.

adb shell am start -n com.android.camera/.Camera

Command to force the system camera to start if the shortcut does not work

Third-party software is especially relevant for older models where MIUI algorithms are no longer updated. New features such as astro mode or improved HDR can be made available through GCam ports, which often have more flexible lens-to-lens switching settings.

💡

Third-party applications like GCam can unlock the potential of the second camera module, but require careful adjustment to a particular smartphone model.
