Owners of the Xiaomi Poco F3 smartphone often face a situation where a standard camera application cannot fully unleash the potential of the hardware. Despite the presence of optical stabilization and a high-quality sensor, the software processing of images in the stock shell of MIUI sometimes leaves much to be desired, especially in difficult lighting. Google Camera (GCam) is a proven solution that can radically change the approach to mobile photography, adding artificial intelligence and improved HDR algorithms.
The process of installing third-party software on Xiaomi devices requires care, since the security system can block the launch of unverified applications. You do not need to have superuser rights or an unlocked bootloader to enjoy the best pictures. Just follow the step-by-step instructions, find a compatible build and properly configure the configuration for your specific Sony IMX686 sensor.
In this article, we will discuss all the stages: from the search for a worker. APK-file to fine-tune parameters through XML-You will learn how to avoid common errors, why an application can close when it starts, and what features should be activated first to get a professional result. F3 It is critical to use builds with support for the Snapdragon 870 processor, as universal versions may not work correctly or open at all.
Preparing the device and searching for a compatible version
The first step is to prepare the operating system to install applications from unknown sources. In modern versions of Android and MIUI, this setting is in the security section. You need to allow the browser or file manager to install programs that are not downloaded from the official Play Store.
Find a reliable source for downloading APK-The most authoritative resource in the community is the developer profile. B.S.G. or Arnova8G2 forum 4PDA or XDA Developers. for the Snapdragon 870 processor installed in Poco F3, The best versions are those labeled "GCam". 8.x" Stable ports of version 7.4.Look for files that mention support in the title ARM64.
Once you download a file, take your time to start the installation immediately. Make sure you have free space in memory and a stable Internet connection for the initial download of libraries. It is also recommended to back up important data, although installing a camera rarely leads to loss of information, it is never superfluous to be safe.
- 📱 Check that Android version is at least 10 (in Poco) F3 usually 11 or 12).
- 🔒 Allow installation from unknown sources in security settings.
- 💾 Download. APK-A file marked as stable for Snapdragon 8xx.
- 📂 Remove old or conflicting versions of Google Cameras if they were installed earlier.
⚠️ Note: Do not download modified ones. APK-files from questionable aggregator sites, overflowing with ads, which can lead to malware infection of the device. Use only verified forums or official Telegram developer channels.
Installation process and initial start-up
Once the file is uploaded, go to the download folder and click on the installation package. The MIUI system can show a bright security risk warning, which is standard procedure, and you need to confirm that you are aware of the risks, and click OK or Allow.
If the app crashes out immediately upon launch after installation, it means that the version is incompatible with your firmware. In this case, try to find a build with the prefix "stable" or "go", which often have wider compatibility, albeit with stripped down functionality. Poco F3 also applies versions that support the library libui.so.
When Google first starts, the Camera will ask for a number of permissions: be sure to provide access to the camera, microphone (for video) and storage. Without permission to access files, you will not be able to save pictures or download configuration files. The initial initialization process can take several seconds.
☑️ Checklist of installation
The interface may be different from the one you're used to in Xiaomi's stock camera, with fewer manual out-of-the-box settings, but more automatic scripting. Don't be afraid of minimalism, because the power comes from the processing algorithms that come into play when you press the shutter.
Configuration of configuration through XML-file
The most important stage for Poco owners F3 is to install the correct XML-It's a text file with settings that adapts the interface and algorithms of Google Cameras to a specific Sony sensor. IMX686. Without this file, you won’t get access to a wide-angle lens, macro mode, or nighttime shooting in its entirety.
Download. XML-A file created specifically for Poco F3 (Sometimes configurable from Mi 11 or Redmi. K40, You can put the file in a folder, and the path may vary depending on the version of the application, but most of the time it's a family of devices:
/Android/data/com.google.android.camera.experimental2021/files/Or, for older versions:
/GCam/Configs8/Once you have the file, start the camera. On a black screen with a double frame, click on the config name or double tap the area next to the shutter button. Select the downloaded profile. The interface should reboot, and the viewfinder will have additional modes such as Night, Portrait and the lens switch.
| Parameter | Recommended value | Influence on photo |
|---|---|---|
| HDR+ Enhanced | Included. | Maximum detail and dynamic range |
| Noise suppression | Average / 20-30% | Remove grains, preserving textures |
| Sharpening (Sharpening) | Low. | Prevents the appearance of artifacts and “soap” |
| Auxiliary Lens | Included. | Activates ultra-wide and macro |
What to do if the config is not used?
Removing common errors and bugs
Even when installed correctly, there can be problems, and one of the common mistakes on the Poco F3 is the black screen when you start up or the purple artifacts in the images, often due to the conflict between the camera drivers in MIUI firmware and the requirements of Google Camera, the solution lies in using special patches or fixes inside the settings of the application itself.
Go to the GCam settings, look for the "About" or "Fixes" section, and there may be items like "Fix black screen" or "Force HAL1." Activating these opsies causes the app to use an alternative camera API, which often solves the compatibility problem.
Another problem is the unstable operation of the zoom. Since the Poco F3 does not have a telephoto lens, digital zoom can cause a severe loss of quality. In the settings, find "Zoom in storage scale" and set a value of 1.0 or 0.8 to improve the crop from the main sensor.

⚠️ Note: If the app is constantly crashing with the error "Camera has stopped", try to clear the cache and data not only of the Google Camera itself, but also of the system application "Camera" in the Android settings.
Secrets of shooting on Google Camera
Once set up, you can get creative. The main difference between Google Camera is the HDR+ algorithm. It takes a series of images with different exposures and combines them into one perfect frame. To get the best result, keep your phone still for 1-2 seconds after you press the down button, especially in low light conditions.
The Poco F3's Night Sight mode works wonders with the main module's large aperture. You don't need a tripod for normal city shots, the algorithm itself compensates for the tremors, but it's still recommended to hover your phone against a stationary object to capture stars or very dark rooms.
Don't forget Portrait mode. On the Poco F3, it works software using depth of field data. For best results, move the subject 1-2 meters away from the background. Artificial intelligence is best at blurring homogeneous surfaces, creating a bokeh effect close to SLR cameras.
💡
To capture moving children or animals, turn off HDR+ Enhanced mode and use regular HDR+. This will speed up the processing of the frame and reduce the chance of getting a blurred face, as the series of shots will be shorter.
Experiment with manual settings. Unlike Xiaomi's stock camera, the GCam allows you to fine-tune white balance and exposure before shooting. Press the focus screen and move the sun slider up or down to change the brightness of the scene without losing detail in the lights.
Results Comparison: Stock vs Google Camera
The difference between a standard app and a port from Google is noticeable to the naked eye. The MIUI stock camera is prone to excessive sharpening and color saturation, which sometimes makes photos unnatural. Google Camera strives for realistic color reproduction and soft but detailed picture.
At night, the advantage of GCam becomes overwhelming. Noise reduction algorithms are more aggressive and smart, keeping textures where stock software just smears parts with noise making. The dynamic range during the day is also wider: the sky doesn't get knocked out white, and shadows remain readable.
It is worth noting that the video is shot in Google Camera on Poco. F3 This can be inferior to the effluent in terms of stabilization and sound quality, so many users keep both applications installed: a GCam for photo and a native camera for recording video and fast scans. QR-code.
💡
The installation of Google Camera makes a good Poco F3 camera phone a flagship tool for photography, especially in the portrait and night photography genres, where Google’s algorithms are unmatched.
