Xiaomi Redmi 7 remains a popular device despite its age, largely due to its reliability and availability. However, owners often find that the pictures taken on the main camera do not look sharp enough or have a lot of digital noise in low light. This is not always the fault of hardware, often the problem lies in the software algorithms of image processing, which are by default set to save resources, not to maximize quality.
Deep diving into the settings of the standard Camera app and using third-party solutions can make a difference. The Sony IMX363 sensor installed in this model has great potential for its class if used correctly. In this article, we will discuss what settings you need to change to get the most out of the optics of your device.
It's important to understand that software interpolation and aggressive noise reduction often eat away at detail, and your job is to balance the naturalness of the picture with the digital processing, and we'll look at both the built-in MIUI tools and the advanced techniques available to mobile photography enthusiasts.
Basic setting of resolution and aspect ratio
The first thing to start optimizing is to check the basic parameters of the shooting. By default, the system can choose modes that are convenient for instant social media posting, but do not save the full frame matrix.
Go to the settings menu by clicking on the three bars in the upper right corner and find the photo size option. Here you should select a value of 4:3 12 MP (or the maximum available, for example, 13 MP). Many users mistakenly choose the 16:9 mode, thinking that this will give a wider frame, but in fact, this mode is just cropping the upper and lower parts of the frame, which reduces the final resolution of the shot.
You should also pay attention to the format of the save. → Advanced settings available for format selection HEIF, It's better to turn it off for maximum compatibility, although it saves space. JPEG high-bitrate.
- 📸 Always choose a 4:3 aspect ratio to use the entire matrix area.
- 🗑️ Avoid digital zoom as it simply crops the frame programmatically, degrades quality.
- ⚙️ Turn off the Improvement Scheiser» (AI Cam) for static objects so that the colours are more natural.
⚠️ Attention: Using digital zoom (two finger pinches) on Redmi 7 results in a catastrophic loss of detail.
Manual ISO management and shutter speed
Automated exposure is often wrong, especially in contrast lighting, and switching to Profi (or Manual) mode gives you complete control over the sensor parameters, and it's the most efficient way to get a clean shot without any noise.
The key here is ISO sensitivity. Automatically, the phone can pick up ISO to 800 or 1600 even in medium light, which creates graininess. Manually, try to keep ISO to a minimum (ISO 100 or ISO 200). If the frame is dark, don't raise ISO, but try to increase shutter speed.
Shutter regulates the time that light hits the matrix. To capture static objects (landscapes, buildings, sleeping people) you can safely set shutter speeds of 1/30 of a second or longer, holding the phone still. However, for moving objects, the shutter speed should be short, no longer than 1/125 of a second, otherwise the lubrication is guaranteed.
Focus in Pro mode is also better switched to Manual Mode (MF) so that the camera does not constantly try to refocus against the background.
- 📉 Here. ISO minimal (100-200) for maximum frame clarity.
- ⏱️ Use a tripod or a stop when holding longer 1/60 seconds.
- 🎯 Fix the focus manually to avoid “breathing” sharpness.
⚠️ Warning: If you're holding your hands long enough, the slightest shaking will blur the frame. If you don't have a tripod on hand, put your elbows against your body or put your phone on a still surface.

Google Camera (GCam) for Redmi 7
One of the most powerful ways to improve the quality of photos on Xiaomi devices in the budget and mid-range is to install a ported version of the Google Camera app (GCam). Google’s HDR+ processing algorithms work wonders with dynamic range, pulling details out of shadows and not overshadowing bright areas.
Not all versions fit Redmi 7 (Snapdragon 632), but the ports from Arnova8G2 or BSG are the most stable. The main difference from stock cameras is using a series of images with different exposures, which are then glued together into one perfect frame, which allows you to get photos that are comparable to the flagships.
After installation APK-You need to download and import a configuration file (.xml) created specifically for your sensor. Without this file, the application may not work correctly or activate the mode. HDR+. Configuration files usually contain optimized noise reduction and sharpness settings.
Where to find the stable version of GCam for the Snapdragon 632?
In the GCam settings, you should turn on HDR+ Enhanced mode if the phone is not overheating, and you can also experiment with the Clearness and Noise Canceling settings in the hidden developer menu, available through a double-click on the About App header.
- 📥 Download GCam only from verified sources (4PDA, Telegram-channels of ports).
- ⚙️ Be sure to import. XML-Configuration for your sensor model.
- 🔋 GCam may consume more battery due to active processor processing.
Comparison of Stock Camera and GCam processing algorithms
To understand the difference in approaches, consider how the standard MIUI app and Google Camera handle a complex light scenario. Xiaomi's standard camera is often prone to oversaturation of colors and aggressive smoothing of skin texture (a beauty effect even in men), making photos "plastic."
Google Camera, by contrast, aims to render realistic color and preserve the skin’s natural texture. The HDR+ algorithm works proactively, processing previews before the shutter is pulled down, which speeds up the shooting process. The table below compares key characteristics.
| Parameter | MIUI stock camera | Google Camera (GCam) |
|---|---|---|
| Dynamic range | Medium, often lost details in the shadows | High, detailed in lights and shadows |
| Color rendering | Bright, rich, sometimes unnatural | Natural, close to reality |
| Noise suppression | Aggressive, "washing" small details | Moderate, retains textures |
| Processing speed | Instant. | It takes 1-2 seconds to process HDR+ |
For landscape photography and architecture, the advantage is clearly on the GCam side. However, for shooting fast-moving children or pets, a stock camera can be faster, since HDR+ mode sometimes creates a “jelly” effect when driving sharply.
💡
Installing Google Camera with the right config is the most effective way to improve the dynamics and color reproduction on Redmi 7 without losing performance.
Optics cleaning and the influence of external factors
Often the problem of poor quality is not the settings, but the banal dirt on the lens.The Redmi 7 smartphone does not have optical stabilization (OIS), so any pollution that scatters light critically affects the sharpness and creates the effect of "fog" or glare from light sources.
Rub the camera with a soft microfiber before every important shot. Fat fingerprints act as a diffuser, blurring the image. It's also worth checking the back glass: if it has deep scratches right above the lens, they will produce persistent glare that can't be removed software.
Lighting is the second critical factor. The Redmi 7 matrix is a physical size typical of public sector workers, so it lacks light. Indoors, try to approach closer to the window. The flash is best used only as a flashlight, since the LED flash on this phone gives a hard, flat light and often illuminates the foreground, leaving the background black.
- 🧹 Wash the lens before each shot, especially indoors in winter.
- 💡 Avoid using a built-in flash for portraits.
- ☀️ Use natural side light to emphasize volume.
⚠️ Warning: Do not use chemicals to clean the chamber. Alcohol or acetone can damage the oleophobic coating of the lens, which will eventually lead to even faster contamination.
💡
To check the lens' purity, turn on the flashlight and shine it at an angle on the camera, and the dust and greasy spots will be clearly visible in the reflection.
Post-processing and third-party editors
Even a perfectly shot often requires minimal correction. The built-in MIUI editor offers basic tools, but third-party apps are better for serious work.
In Snapseed, you can look at the Point tool, which removes small defects (dust on the sensor, pimples on the skin), and the Correction tool will help you gently increase the structure and detail without affecting the general sharping, which often looks unnatural.
If you shoot in manual mode, you can get the file in format. DNG (RAW), If your version of the software or GCam supports it. RAW-The files contain raw data from the matrix, which looks faded, but they offer tremendous opportunities to pull shadows and correct white balance without loss of quality, which is critical for the Redmi 7 in difficult conditions.
- 🎨 Use Snapseed for quick retouching and adding structure.
- 📉 Reduce the noise carefully so as not to lose the texture of hair and fabric.
- 🌈 Adjust the white balance if the photo is yellow or blue.
Don't overdo filters. Often, just increase the contrast and add a little saturation to make the photo play, and the main rule of post-processing is not to overdo it, so that the photo remains realistic.
