When choosing a Xiaomi Redmi Note 7 smartphone, many people pay attention to its camera, because the manufacturer has been actively advertising the β48-megapixel sensor.β But in practice, everything turns out to be not so clear: in the camera settings you can see the resolution of 12 MP, and where is the promised 48 MP? This confusion arises due to the features of the Sony sensor IMX586, which uses pixel binning technology.
In this article, we will look at how many megapixels the Redmi Note 7 camera actually gives in different shooting modes, how to turn on full 48 MP resolution, and whether to do it. A50 And the Honor 10 Lite, and we'll give you some practical tips for setting up the best photos, and if you're planning to buy or you're already using this smartphone, you'll find all the answers to all the questions about its camera.
Redmi Note 7 camera specifications: what is hiding 48 MP?
Xiaomi Redmi Note 7 Main Camera Is Equipped With Sony Sensor IMX586 But by default, the smartphone takes pictures in 12 MP mode, which is not a hoax, but the result of Tetra-Cell technology).
How does it work? Four adjacent sensor pixels are combined into one superpixel size. 1.6 So microns, which improves light sensitivity and reduces noise in low light conditions β 4000Γ3000 pixel (12 MP), but full activation can be made if necessary 8000Γ6000 pixel (48 MPP).
- πΈ Main camera: 48 MPP (f/1.8, 1/2", 0.8 ΞΌm), autofocus with phase detection (PDAF)
- π Wide-angle camera: 5 MPP (f/2.2, 1.12 ΞΌm), angle of view 83Β°
- π Front camera: 13 MPP (f/2.0, 1.12 ΞΌm), support HDR
- π₯ Video: 4K@30fps, 1080p@30/60/120fps, gyroscopic stabilization
It's important to understand that 48MP doesn't always give you better quality -- it's only useful in good lighting and for later cropping. In most cases, 12MP processing algorithms show a more balanced result.
How to turn on 48 MP shooting on Redmi Note 7?
By default, the Camera app activates 12 MP mode. To switch to full resolution, follow the following steps:
- Open the Camera app.
- Touch the icons βοΈ Settings (cog in the upper right corner).
- Select the photo resolution option.
- Activate the 48 MP option (some firmware may call it High Resolution).
After that, all photos will be saved in resolution. 8000Γ6000 Notice that you're not going to see pixels:
- π The size of one image will increase with ~3-4 MB up to ~15-20 MB.
- β‘ Shooting in 48 MP can slightly slow down the camera (latency between frames) ~1-2 seconds).
- π Battery consumption during long shooting will increase by 10-15%.
Clean the memory of the smartphone (minimum) 2-3 GB is free)
Use the class memory card UHS-I (U3) fast-record
Turn it off. HDR manually (it is automatically activated at 12 MP)
Charge the battery at least 50 times%-->
β οΈ Attention: In 48 MP mode, some processing functions are disabled, such as night mode and artificial background blur (bokeh.
12 MP vs 48 MP: Which is better in practice?
To understand when to use full resolution, we ran tests in different conditions, and the results are shown in the table below:
| Filming conditions | 12 MP (binning) | 48 MP (full) | Recommendation |
|---|---|---|---|
| Bright sunny day | Good detail, natural colors | Maximum detail, but overcharging is possible | 48 MP (if zoom or framing is needed) |
| Cloudy weather | Less noise, better white balance | Noise in dark areas, worse dynamic range | 12 MPs |
| Night photography | It is night mode, less noise. | Night mode is off, there's a lot of noise. | 12 MPs + night-time |
| Portrait photography | Natural background blur (bokeh) | Background blur missing | 12 MPs |
| Video | 4K@30fps stabilizing | 4K@30fps without binning (worse light sensitivity) | 12 MP (binning is automatically enabled) |
The 48 MP is justified in two cases:
- You plan to cut a photo (for example, make a zoom). Γ2-Γ3).
- The shooting takes place in perfect lighting (studio or bright sun).
π‘
In 90% of cases, 12 MP is the best result due to software processing, the full 48 MP is only needed for professional framing or printing in large format (A3 and above).
Secret camera settings Redmi Note 7 for the best photos
Even in 12MP mode, the Redmi Note 7 can do more if you adjust the settings correctly.
1.Switch off Xiaomi watermark
The default is to put the brand logo on all photos, to remove it:
- Open the camera. β Settings β Watermark.
- Move the slider to the off position.
2. Activate the shooting in the format RAW
Files.DNG save as much information as possible for post-processing. β Format β RAW. Minus - file size ~25MB in the picture.
3.Tune the white balance manually
Automatic white balance is often mistaken in artificial lighting rooms. Go to Professional Mode (Pro) and select the appropriate preset (incandescent lamp, fluorescent lamp, etc.).
4.Use manual focusing for macro
In Pro mode, touch the object on the screen and hold your finger to block the focus. Then adjust the distance manually so you can take photos of objects from a distance. 5-10 centimeter.
π‘
To capture moving objects (children, animals) turn on Continuous Shooting in the settings. The smartphone will take up to 20 frames per second, and then you will choose the best one.
5. Optimize your video settings
- ποΈ For smooth video, choose 1080p@60fps permission settings.
- π Turn off noise cancellation if youβre recording music or an important sound, which is bad for quality.
- π Turn on the grid (Settings) β Grid) for the correct composition.
Comparison with competitors: who won in 2019?
In the year of release (January 2019), the Redmi Note 7 was one of the first smartphones with a 48-megapixel camera in the budget segment.
| Model | Main camera. | DxOMark (2019) | Strengths | Weaknesses |
|---|---|---|---|---|
| Xiaomi Redmi Note 7 | 48 MPP (IMX586, f/1.8) | 90 | Details in good light, price | Night photography, autofocus in the dark |
| Samsung Galaxy A50 | 25 MPP (f/1.7) + 5 MP (wikipedia) + 8 MP (telephoto) | 83 | Stable autofocus, AMOLED-screen | Low detail, noise |
| Honor 10 Lite | 24 MPP (f/1.8) + 2 MP (depth) | 81 | Compact, fast shooting. | Absence 4K-Video, weak dynamic range |
| Realme 3 Pro | 16 MPP (IMX519, f/1.7) + 5 MP (depth) | 88 | Night mode, speed of shooting. | No wide-angle module. |
The Redmi Note 7 was a solid leader in detail during the day, but lost in night shooting and video stabilization. IMX519 (OnePlus 6T) The best results in the dark due to the optimized night mode.

Typical Redmi Note 7 Camera Problems and How to Fix Them
Despite the impressive specs, users often encounter bugs and camera limitations.
1.The camera focuses for a long time or does not focus at all
Reasons:
- π§Ή Contaminated lens (wipe with soft cloth).
- π Software failure (reset your smartphone or reset your camera settings in Settings) β Annexes β Camera. β Warehouse β Clear the data).
- π οΈ Autofocus damaged (required repair).
2. photos are obtained blurred or with noise
Decisions:
- π Low light shooting: Use Night Mode or an additional light source.
- π± Turn on Stabilization in the settings (helps with hand tremors).
- π Check if your finger is covering a flash or lens.
3.The video twitches or brakes
The problem is typical for shooting in 4K@30fps Weak memory cards:
- πΎ Use the class memory card UHS-I (U3) or V30.
- ποΈ Switch to the switch. 1080p@60fps β less processor load.
- π Charge the battery to 100% (at low charge, the smartphone limits performance).
β οΈ Note: If after the update MIUI the camera has become worse (for example, the night mode has gone missing), try to roll back to the previous firmware version via Settings β The phone. β Updating the system β Three points. β Select a Service Package.
