Introduction: Why setting up the Redmi 9 camera needs attention
Smartphone Xiaomi Redmi 9 is equipped with a module of four cameras (13 MP main + 8 MP ultra-wide angle + 5 MP macro + 2 MP depth sensor), but by default its capabilities are used only 30-40%. Even the budget matrix is able to give high-quality images - if you correctly configure the software part and understand the logic of the MIUI Camera algorithms.
The problem is that the manufacturer hides some of the features behind non-obvious gestures or deep in the menu. For example, night mode automatically turns off when shooting in 4K, and manual focusing is only available through long retention on the screen, this article will help you understand all the nuances from basic parameters to advanced tricks, which are silent even the official guides.
We tested all the modes on firmware. MIUI 12.5–MIUI 14 (including the global and Chinese versions, and identified key factors that affect the quality of the images, such as the inclusion of the option"AI-The camera in some scenes worsens the detail on the 15-20%, And this is the real challenge, despite the promise of "improvement.
Basic camera settings: what to change first
Before you dive into the shooting modes, check the basic parameters that affect all photos. They are hidden in the settings menu (the gear icon in the upper right corner of the camera interface).
- 📸 Photo resolution: set 13 MP (4:3) is the sensor's native resolution. 9 MP (16:9) just cuts the frame around the edges without adding details.
- 🎥 Video resolution: Full is enough for most tasks HD (1080p) 30 fps. 4K Redmi 9 shrinks bitrate to 12 Mbps, which causes artifacts to appear when moving.
- 🔄 Save settings: turn on the option "Save camera settings", otherwise after closing the application all settings will reset.
- 🌙 Night mode: activate "Car-night mode", but turn off "AI-camera in the dark – it often overstates the exposure, blurry details.
Pay special attention to the "Watermark" tab (Additional tab), which is the default camera that embeds phone model and shooting date data into EXIF, which not only reveals your privacy, but also increases the file weight by 5-10%.
💡
If after the MIUI update, some settings (for example, manual shutter speed) have disappeared, reset the camera settings to factory settings: Settings → System → Resetting → Resetting application settings → Camera.
Shooting modes: what when to use
The Redmi 9 camera interface offers 7 basic modes, but not all of them are equally useful.
| Regime. | When to use | Limitations |
|---|---|---|
| Photo Photo | Universal mode for daytime shots. It does well with portraits and landscapes in good lighting. | In cloudy weather, it automatically overstates the ISO, which causes noise. Solution: manually set the ISO to 400-800. |
| Portrait | For people with blurred backgrounds (bokeh effect) only works at a distance of 0.5-2 meters from the subject. | Artificial blur often eats away at the edges of hair or small details. Check the result on the screen before saving. |
| Night mode. | Low light shooting (evening, dim light rooms) keeps the camera open for up to 3 seconds. | It doesn't work with moving objects (it'll be lubricated). It requires the phone to be absolutely stationary -- use a tripod. |
| Macro | For shooting small objects (insects, textures, ornaments) from a distance of 2-5 cm. | The 5MP macro camera has a fixed focus and low aperture. In the dark, quality drops dramatically. |
| Wide-angle | Landscapes, architecture, group photos in cramped spaces, viewing angle: 118°. | Severe edge distortion (fish-eye effect) reduced to 8 MP resolution, detail worse than the main camera. |
The hidden Pro mode is activated by the swipe to the left of the Video mode, where you can manually adjust ISO, shutter speed, white balance and focus, which is useful for shooting glowing objects (lights, fireworks) or creating the effect of "light strokes" (for example, from cars in the night city).
Advanced settings: how to squeeze the most out of the camera
To make the shots much better, you'll have to dig into the hidden parameters and alternative methods. Here's what really works on Redmi 9:
- Shutdown AI-Cameras: The AI algorithm often miscalculates white balance and saturation "AI-And compare the results before and after, and the difference is particularly noticeable when you're shooting the sky or the greens.
- Using GCam: Google Camera port for Redmi 9 (e.g. BSG or Wichaya version) gives more natural colors and better HDR processing. Download the 4PDA forum (see "GCam for Redmi 9" theme).
- HDR setting: Turn on HDR Auto in the settings, but manually turn it off when shooting moving objects – the algorithm can create “ghost” artifacts.
- Focus by touch: Long-term retention on the subject on the screen blocks focus and exposure (AE/AF Lock) Useful for shooting against light or when you need to fix parameters before the frame.
There's a separate life hack for video: if you want to record long video without overheating, lower the resolution to 720p and turn on "Stabilization." This will reduce the CPU load, and the phone won't brake after 10-15 minutes of recording.
How to install GCam on Redmi 9
Redmi 9 camera errors: how to fix common problems
Even after setting it up properly, users are faced with typical bugs, and here are the most common ways to solve them:
- 🔴 Camera not focusing: Wipe the lens with a soft cloth (fat spots interfere with autofocus). If the problem remains, reset the camera settings or check if macro mode is on (it blocks the autofocus of the main camera).
- 📉 Grainy photos in the dark: Night mode is no panacea. Try to reduce ISO manually 800 and increase the exposure to 1/4 seconds (use a tripod!).
- 🎥 Video twitches: Turn off "Stabilization" in video settings - sometimes it conflicts with algorithms MIUI. If it doesn't help, lower the permission to 720p.
- 🔄 Camera app crashes: Clear cache (Settings) → Annexes → Camera. → Warehouse → Clear the cache and restart the phone. If the error repeats, update it. MIUI.
⚠️ Warning: If the camera is blurry after the phone falls, it's a sign of damage to the lens or the matrix. This cannot be fixed by itself, you need to replace the module at the service center.
Another common problem is the jelly effect, which is a hardware feature of stabilizing on budget smartphones, so to minimize the effect, keep your phone closer to your body while you're shooting and avoid sudden movements.
☑️ Checklist before the big shot
Comparison with other Xiaomi smartphones: is it worth updating?
If you're thinking about changing phones, it's useful to compare the capabilities of the Redmi 9 camera to the newer ones, and we tested several devices under the same conditions (daylight, portrait, night photography) and here's what we found:
| Model | Daytime photos | Portrait | Night photography | Video |
|---|---|---|---|---|
| Redmi 9 | Good detail, but oversized saturation of green. | Satisfactory bokeh, but "eats" the edges. | Medium quality, a lot of noise. | Full HD 30fps is acceptable, 4K is artifacts. |
| Redmi Note 10 | More natural colors, better dynamic range. | Exact separation of object and background. | Night mode works faster and with less noise. | Stabilizing video at the level of flagships of 2020. |
| POCO X3 Pro | Similar to Redmi 9, but better HDR processing. | It uses the same portrait-taking algorithm. | Night mode is slightly better due to a more powerful processor. | 4K video is acceptable, but overheats after 10 minutes. |
The bottom line is that if you’re happy with the quality of Redmi 9 for everyday tasks (social media, family photos), it doesn’t make sense to upgrade for the camera, but if you’re interested in nighttime shooting or professional video, you should consider models with a Snapdragon 7xx and higher processor (for example, the Redmi Note 11 Pro or POCO F4).
💡
Redmi 9 does a great job of daytime shots and portraits in good lighting, but loses in night shooting and video due to a weak processor and budget matrix.
Alternative Camera Apps: Which Is Better Than Standard Camera Apps
Built-in camera MIUI It's not always a good job, especially in difficult environments.-3 Alternatives that are worth trying:
- Google Camera (GCam) Pros: better HDR processing, natural colors, Night Sight night mode outperforms the regular. Cons: no macro camera support, sometimes flies to MIUI. Where to download: celsoazevedo.com (look for versions for Snapdragon 662).
- Open Camera Pros: Full manual control (sustain up to 30 seconds!), RAW support, no ads. Cons: interface overload, no portrait mode. Where to download: Google Play.
- Footage Pros: Specializes in video, supports LOG-Post-processing profile, better stabilization than regular. Cons: paid version is needed to unlock all features.
Important: Before installing alternative cameras, turn off battery optimization for them (Settings → Battery → Battery Optimization → Select an app → No restrictions).
⚠️ Note: When using GCam on Redmi 9, some features (such as Astrophotography) may not work due to the limitations of the Snapdragon 662 processor.
