How to turn on a wide-angle camera on Xiaomi Mi 9T

The Xiaomi Mi 9T is often called the king of the mid-range, thanks to its frameless design and, of course, triple main camera. Many users buy this model precisely for the sake of the ability to shoot panoramic landscapes and architectural objects using ultra-wide viewing angle. However, unlike some other models, switching between lenses here is not always automatic or obvious to the beginner. In standard mode, the camera application is configured to use the main 48-megapixel module, which gives the most detailed picture in normal conditions.

The wide-angle lens in the Mi 9T has an 8MP matrix and a 120-degree viewing angle, which allows you to capture much more space than you can with the "main" camera. This is especially true when shooting in tight spaces or in nature, when you need to put a high waterfall or a group of people in the frame. Activating this module requires understanding the logic of the MIUI interface, because there is no explicit physical button to switch lenses on the device body. All control is software through the touch screen.

In this article, we will discuss in detail the algorithm for forcing or automatically turning on a wide-angle camera. You will learn why sometimes the camera does not switch, how to use zoom to change lenses and what hidden settings can affect the quality of your shots. We will also touch on the topic of software failures that can block the operation of auxiliary modules, and suggest ways to solve them without flashing the device.

Design of the camera module Xiaomi Mi 9T

Before you get to the software settings, it’s important to understand what hardware you’re working with. The Xiaomi Mi 9T photo system is based on a triple camera unit located vertically in the upper left corner of the rear panel. The main element is the core 48MP Sony IMX586 module, which is responsible for detailing and low-light operation, and it’s the one that is activated by default when the app is launched.

The second key element is a 2x telephoto zoom lens, which allows you to zoom in without losing quality. And finally, the third component is the ultra-wide-angle lens that we're interested in, which has a fixed focal length and a 120-degree viewing angle, and the switching between these modules is not mechanical, but by activating the corresponding sensors and processing the data by the image processor.

⚠️ Warning: Do not physically press on camera lenses or disassemble the module in the hope of manually switching the lens, which will cause permanent damage to optical stabilization and dust to the lenses.

It's worth noting that the smartphone's software decides which lens to use depending on the zoom level the user chooses. However, MIUI algorithms don't always perfectly guess the photographer's intentions, especially when the composition of the frame changes dramatically. Understanding the physical characteristics of each module helps predict the behavior of the camera and adjust the scene correctly before shooting.

Below is a table showing the main characteristics of each of the three Xiaomi Mi 9T camera modules to help you better navigate the device’s capabilities:

The main method of activation through zooming

The easiest and most commonly used way to switch to a wide-angle camera is to use a zoom slider in the app interface. When you open the standard Camera app, the default mode is 1x, which corresponds to the main lens. To enable wide-angle mode, you need to click on the 0.6x icon, which is usually located to the left of the shutter button or at the bottom of the screen depending on the orientation of the smartphone.

Once you touch 0.6x, the system instantly switches the active sensor from the main 48 MP module to 8 MP wide-angle. Visually, you will notice the image in the viewfinder "goes back" and the frame will get much more objects at the edges. If the icon "0.6x" is not on the screen, try to pinch two fingers on the screen (to bring your fingers together), simulating the action of distance. This action should also activate the wide-angle lens.

6x image quality can be subjectively reduced, due to the smaller size of the matrix and the lack of optical stabilization on the wide-angle module, however, for landscape photography or architectural photos, this is standard behavior and does not indicate a malfunction.

💡

When shooting at 0.6x, try to keep your smartphone as smooth as possible. A wide-angle lens distorts perspective more when tilted, which can cause vertical lines of buildings to "close down".

Sometimes users are faced with a situation where when pressing 0.6x nothing happens, or the camera returns to 1x mode. This can be caused by a software failure or the fact that in the current shooting mode (for example, "Portrait" or "Night mode" in some versions of the firmware), the use of auxiliary lenses is limited to developers.

Setup shooting modes for a wide angle

Not all modes of camera Xiaomi Mi 9T available to switch to a wide-angle lens. Standard mode "Photo" supports full functionality, but if you switch to specialized scenarios, how options can change. For example, in "Portrait" mode, the use of wide-angle camera is often disabled, as the algorithms blur the background (bokeh) sharpened to work with the main lens with phase autofocus.

To activate a wide angle in non-standard situations, you need to manually select the appropriate modes in the swipe menu to the right or left. In Video mode, switching to 0.6x is available, but with a resolution restriction. Most often, wide-angle shooting in video is only available in 1080p at 30 or 60 frames per second. If you set the maximum 4K resolution, the system will forcibly switch to the main sensor, and the 0.6x button will become inactive.

• 📸 Photo mode - full support 0.6x, 1x, 2x.
• 🎥 Mode "Video" — 0.6x available only 1080p 60fps.
• 🌙 Night mode – wide angle may not be available or operate with long exposure without stabilization.
• 🤳 Portrait Mode - Switching to 0.6x usually blocked.

Also worth paying attention to the aspect ratio settings. When choosing a Full or 18:9 format, the camera uses the entire matrix area. However, when switching to a wide-angle lens, some versions of MIUI may crop the image, which visually reduces the viewing angle.

If you plan to actively use a wide-angle camera for video blogging, check the microphone in advance. When switching lenses, the audio stream may be briefly interrupted or change the nature of noise cancellation, as the system redistributes the processor resources.

Use of additional functions and filters

The wide-angle camera on the Mi 9T offers access to a number of unique creative capabilities that are not available on the main module. One of these features is the Long Exposure mode in conjunction with a tripod, where a wide angle allows you to capture the movement of clouds or light tracks of cars over a larger frame area. To activate this mode, go to the “More” menu and select the appropriate option.

And the camera interface also offers special filters and effects that are particularly good at ultra-wide coal. The distortion of perspective around the edges of the frame, which is a physical property of wide-angle optics, can be used artistically, for example, by shooting architecture from the bottom up, you'll highlight the grandeur of buildings, and when you shoot interiors, you'll create a sense of vast space.

In the camera settings (the icon of three stripes in the corner of the screen), you can find the item responsible for correcting distortion. On the Xiaomi Mi 9T, the software distortion correction is enabled by default for a wide-angle lens. If you turn it off, the edges of the frame will become more "puffy", which is characteristic of the "fish eye".

And remember, macro photography. While there's no separate macro lens on the Mi 9T, the wide-angle camera allows you to get very close to the subject, keeping both the subject and part of the background in focus, and it creates an interesting immersion effect that's highly valued in mobile photography.

Solving problems with switching lenses

Despite the reliability of the Xiaomi Mi 9T, users may experience software errors in which the camera refuses to switch to wide-angle mode. The most common reason is the freezing of the image processing process. In this case, simply closing the camera application does not always help. It is recommended to completely clear the device’s RAM through the menu of recent apps and restart the smartphone.

The second reason may be conflicts with third-party camera apps installed (e.g. Google Camera or Open Camera). If the regular camera starts to behave incorrectly after installing such programs, try removing them or clearing the Camera app data in the system settings. To do this, go to Settings → Apps → All Apps → Camera → Clear the data.

⚠️ Warning: Clearing the Camera application data will reset all your user settings (grid, shutter sound, saved settings) HDR) Your photos and videos will not be affected.

The problem may also be in an outdated firmware version. Xiaomi periodically releases updates that correct errors with the camera modules. Check for updates in the Settings menu → About Phone → MIUI version. If a new version is available, install it by backing up the data beforehand.

In rare cases, the problem is hardware in nature: the camera plume may have moved away after a fall or moisture. If the software methods do not help, and the camera emits strange clicks or emits an error "failed to connect to the camera", most likely, a diagnosis will be required at the service center.

Tips for getting better results

To make your shots on the Xiaomi Mi 9T wide-angle camera look professional, follow a few simple composition rules. First, try not to place important objects (such as people's faces) around the edges of the frame. Due to optical distortion, they may look stretched or unnatural. The center of the frame at ultra-wide angle remains the most geometrically correct.

Second, use perspective lines. The wide angle is perfect for taking pictures of roads that go out into the distance, rows of columns or long corridors. Directing those lines from the bottom corner of the frame to the center or opposite top corner will create a powerful effect of depth and dynamics.

Third, watch the lighting. The 8MP matrix is less sensitive to light than the main module. At dusk or indoors, without good lighting, the images can be noisy. In such situations, it is better to switch to the main lens and use digital zoom, the quality will be higher than the "digital noise" of the wide angle.

💡

The main secret of high-quality wide-angle shooting on the Mi 9T is to find the foreground. Get close to the interesting object (flower, stone, architectural details) so that it occupies a significant part of the frame, and the wide angle will beautifully blur and expand the background.

Experiment with the horizon. In standard photographs, a blocked horizon is considered a mistake, but at an ultra-wide angle, a slight tilt can add dynamics and drama to the scene, especially when shooting sea waves or city streets.
