The Xiaomi Redmi Note 7, which came to market as the “king of the budget segment”, is still a popular device due to its excellent price-performance ratio. However, the built-in regular camera application often does not allow you to fully realize the potential of the 48-megapixel matrix Sony IMX586 installed in this device.
The solution to this problem is a ported version of Google Camera (GCam), developed by enthusiasts specifically for the Snapdragon 660 processor, which brings image processing algorithms from Google’s flagship Pixel phones, which radically changes the approach to mobile photography. For Redmi Note 7, it is critical to use modified GCam versions. 7.x or 8.x, as standard APK-Files from other devices will not start without editing the configuration file.
In this article, we will discuss the process of installing, configuring and optimizing an app to get studio-quality shots. You will learn where to look for proven builds, how to activate Night Sight mode for night shooting, and what HDR+ settings need to be changed for the best result. Preparation will take no more than 15 minutes, but the effect of using new software will remain with you for the entire duration of your smartphone ownership.
Why you should replace the regular camera on the Redmi Note 7
The manufacturer’s MIUI Camera app is often pre-installed with aggressive software processing. Xiaomi’s algorithms tend to over-lighten shadows and saturate colors, making photos look like digital painting rather than real images. In addition, the dynamic range in standard mode often suffers: the sky is knocked out white and details in dark areas are lost.
Using Google Camera, you can use the processing power of the processor in a different way. Google's HDR+ algorithms take multiple frames with different exposures and combine them, saving as much detail as possible in lights and shadows, and this is especially noticeable when shooting contrasting scenes, such as landscapes with bright sun or interiors with windows.
Another important advantage is noise management. At night or in dim light rooms, the Redmi Note 7 with a standard camera creates porridge from color artifacts. GCam uses multi-layer noise reduction, which preserves textures but removes digital grain. Video quality can also be improved by better stabilization and microphone performance in some builds.
⚠️ Attention: Third-party installation APK-The file requires permission to install from unknown sources. Make sure you only download the file from trusted resources, such as 4PDA or the official developer channel to avoid viruses.
It’s important to understand that not all features can work perfectly. For example, the ultra-wide-angle camera in the Redmi Note 7 (if it’s active in the build used) may require separate setup or work unstable. However, the core module with a 48 MP matrix works perfectly, providing detail that is not available to factory software.
Preparation of the smartphone for the installation of GCam
Before you start installing, you need to do a number of preparatory steps to avoid version conflicts and launch errors, especially if your device already has any versions of Google Camera from other developers, you should remove them or temporarily disable them so that there is no confusion with permissions.
You will need access to the file system and the ability to install applications from third-party sources. In modern versions of MIUI (MIUI 11, 12 and later) based on Android 10 and above, permissions are issued individually for each installer application (browser or file manager).
☑️ Checklist of Redmi Note 7 preparation
It’s also worth checking out the Android version. Android 9 (Pie) and Android 10 versions are relevant for the Redmi Note 7. Android 11 and above may require specific GCam builds marked as compatible with the new permissions system. Make sure you have a stable internet connection to download additional libraries if they’re required on your first run.
Remember to back up important contacts and settings, although the GCam installation process rarely results in data loss. However, experimenting with configuration files may require resetting the camera app itself, so the safety net is fine.
Choosing the Right Version of Google Camera
Choosing the right APK is the most critical step. Since the Redmi Note 7 is based on the Qualcomm Snapdragon 660 processor (arm64-v8a architecture), you need builds marked as compatible with this architecture. Universal versions may not start or fly out immediately after opening.
The most stable versions for this model are those from developer BigKaka (also known as Arnova8G2) and BSG. Versions 7.x (such as 7.4 or 7.6) often run faster and more stable on older processors than heavy 8.x versions. However, if you want to get a "Portrait Mode" feature with improved blur, it's worth trying the GCam 8.1 or 8.8.
- 📸 GCam 7.4 (BigKaka): Perfect balance of speed and quality, minimum battery consumption, stable and sustainable HDR+.
- 🌙 GCam 8.1 (BSG): Improved Night Sight mode, video support 4K (It depends on the build, but it can work slower.
- ⚡ GCam Go: Google’s lightweight version, works very fast, but has a stripped down functionality and fewer settings.
- 🛠 GCam 8.8 (Shamim/Hasli): Maximum number of manual settings for enthusiasts, requires fine tuning for the Sony sensor.
When downloading, pay attention to the end of the file. Redmi Note 7 often fits files with the suffix arm64-v8a.apk. Avoid versions for MediaTek or Exynos processors, as they contain specific libraries that are incompatible with your device. If the application crashes when you start, try the version marked "Go" or older stable build.
Step-by-step instructions for installing an APK file
The installation process MIUI It's different because of the strict security policy, after you downloaded the selected one. APK-The file, don't rush to open it right away. First, you need to make sure that the system allows installation.
Go to Settings → Applications → Application Management. Find your browser (Chrome, Mi Browser) or file manager from which you will run the file. Click on it, select Other permissions, and activate Install Unknown Applications. Without this step, the system will block the process.
Now open the downloaded file. You'll see a warning window. You'll hit OK or Allow. Then you'll see the standard Android installer window. You'll hit Set. Wait until the process is over and you'll hit Open.
When you first run, GCam will ask for permissions like camera, microphone, memory and geolocation, and you have to resolve all requests, otherwise the app won't function properly, and if you don't access the memory, you won't be able to save photos.
⚠️ Warning: If you see a black screen instead of a viewfinder after installation, try restarting your smartphone. In rare cases, you need to re-install it with the complete removal of previous versions.
What to do if the installation is blocked by the security system?
Configure the configuration and shooting parameters
Simply installing the app isn’t enough – it’s critical for the Redmi Note 7 to use the correct configuration file (XML) that contains pre-built settings for a particular camera sensor, eliminating the need to manually select hundreds of values.
Find the configuration file (usually.xml extension) for the GCam version you installed. Download it and place it in /GCam/Configs7/ (for version 7.x) or /GCam/Configs8/ (for version 8.x) in the phone's internal memory. If there are no folders, create them manually, observing the letter register.
Once you have placed the file, launch Google Camera. On the black field of the viewfinder, double-click in an empty place (to the right or left of the down button). A menu will appear with a list of available configurations. Select a file that matches your model (for example, Redmi Note). 7_BSG_8.1.xml). The app will restart with new settings.
In manual settings mode (Settings → Advanced → Auxiliary camera), you can check if the wide-angle lens is activated if your build supports it. It is also recommended to enable the Enable 60fps option for video if the processor copes to get a smoother picture.
| Parameter | Recommended value | Influence on photo |
|---|---|---|
| HDR+ Enhanced | Included. | Maximum detail and dynamic range |
| Night Sight | Auto / On | Improves shooting in the dark, reduces noise |
| Auxiliary Camera | Included. | Activates additional modules (width/macro) |
| Video Stabilization | EIS On | Smooths the shaking of hands while recording video |
| JPEG Quality | 95-100% | Increases file size but retains details |
💡
Tip: For portrait photography in GCam settings, find Portrait mode and select the degree of background blur. On Redmi Note 7, it is better not to set the maximum value so that there are no artifacts around the edges of the object.
Solving problems and mistakes
Despite the careful preparation, users may encounter technical problems, the most common of which is the launch of the application, often due to incompatibility between the Android version and the GCam version.
Another common problem is the green screen or the purple stripes in the photo, which is a sign that the noise-canceling algorithms for your sensor are not working properly. XML-Configurator designed specifically for Sony sensor IMX586.
- 📉 Low speed of photo saving: Disable in the settings "Save the original" or reduce the quality JPEG. Snapdragon 660 processor may not be able to handle fast processing RAW-file.
- 🔋 Fast battery drain: GCam consumes more resources.Stop geotagging and keep viewfinder running in the background.
- 📹 Video without sound: Check microphone resolutions in Android settings. sometimes resetting app permissions helps.
- 🌫 Turbid photos while moving: Turn on stabilization or use a tripod as shutter speed is in mode HDR+ may be long.
⚠️ Warning: If the phone starts to get very hot when using GCam, take a break. Prolonged processing of high-resolution photos puts a strain on the processor, which can be stressful for a budget device.
In some cases, cleaning the app cache helps. Go to Settings → Apps → Google Camera → Memory → Clear the cache. This won’t delete your settings, but it can remove temporary files that cause crashes.
Comparison of results: Staff camera vs GCam
Once you've tuned in, you'll notice a big difference, and in the daytime, the images will become more natural, the soapiness around the edges of the frame will disappear, the colors will stop being acidic, and the white balance will more accurately convey the atmosphere of the scene, especially in difficult lighting conditions.
At night, the difference becomes enormous. Where the regular camera draws noisy porridge with lubricated lights, the Google Camera pulls details out of the darkness, making the night look like dusk. The Night Sight mode on the Redmi Note 7 works wonders, allowing you to take pictures even in the light of the moon.
💡
The main takeaway: Installing GCam is the only free way to turn a mid-level camera into a flagship-level shooting tool, leveraging the potential of Google’s algorithms.
But remember, GCam is a third-party product that can be updated less frequently than regular software, and some specific MIUI features (like certain filters or cloning modes) may not be available, but for the high-quality photographer, the choice is obvious.
Experiment with settings, try different ones. XML-Mobile photography on Redmi Note 7 with Google Camera opens up new horizons of creativity without having to buy a new phone.
