Xiaomi Redmi 8 remains a popular budget device, but over time, the standard software no longer meets the growing needs of users in mobile photography. Standard image processing algorithms often do not cope with difficult lighting conditions, which forces owners to look for ways to upgrade. Fortunately, the architecture of the Snapdragon 439 processor allows you to implement third-party solutions that significantly expand the functionality of the main module.
The process of improving photo capabilities does not always require obtaining super-user rights, although it opens up more possibilities. There are several proven methods, ranging from simply replacing the system application to installing modified versions of Google Camera. The choice of the specific path depends on your technical training and the desired result.
Before taking active action, you need to be aware of the risks. Any interference with system files can lead to unstable operation of the device. APK-files on Redmi 8 require a complete backup of data, as rollback of changes may not be possible without flashing.
Current status analysis and preparation
The first step should always be to diagnose the current version of the software. Redmi 8 owners need to make sure the underlying firmware is available. MIUI It is relevant because older versions may have compatibility conflicts with new camera modules. → The phone. → Version. MIUI.
Then you need to make room for memory. High-quality photo processing algorithms require a temporary buffer, and a crowded drive will lead to application crashes. Delete unnecessary caches and heavy files to ensure the stability of the system while testing new versions of the software.
It is also important to enable USB debugging and allow installation from unknown sources, which are located in the hidden developer menu, which is activated by seven times pressing the build number in the About Phone section, without these settings, the installation of modified packages will be blocked by the security system.
☑️ Redmi 8 Preparation for Camera Update
Don't ignore this stage, because rush often leads to errors. Competent preparation reduces the time to fix possible problems in the future. The system must be in a "clean" state for new algorithms to work correctly.
Official update through system settings
The safest, but not always the most effective, way is to use the built-in updater. Xiaomi periodically releases patches that fix focus and color rendering bugs. To check, go to Settings → About Phone → System Update and press the check button.
If the system says there is no update, but you know about the release of a new version, you can use the manual file selection function. The recovery archive downloaded from the official website should be placed in the root of internal memory. After that, in the update menu, click on three dots in the corner and select "Select firmware file".
⚠️ Attention: Interrupting the official firmware process at the stage 30-70% Make sure that the smartphone is securely attached to the docking station or lies on a hard surface where no one will touch it.
Once the official update is installed, it is recommended to reset the camera settings, which will clear old configuration files that may conflict with new drivers. Go to the settings of the Camera application and find the Reset option at the bottom of the list.
💡
Before installing the official update via the recovery file, remove all third-party launchers and themes to avoid cyclical system restarts after restart.
Install Google Camera (GCam) for Redmi 8
The most powerful way to radically improve the quality of images is to install a ported version of Google Camera. Google’s HDR+ and Night Sight algorithms work wonders even on the budget sensors Samsung S5K4H7 or Omnivision OV8856, which are used in the Redmi 8.
The installation process requires finding the right build (port). Since the Snapdragon 439 processor is from the 400 series, you need versions of the GCam labeled Go edition or specially adapted for SDM439 chipsets. Universal flagship versions may not start or work properly.
- 📸 GCam Go - a lightweight version, stable on budget processors, supports portrait mode.
- 🔧 MGC — Modifications from developer BigKaka, often have settings for specific sensors.
- ⚙️ BSG — Popular ports that require you to select a configuration file (.xml) for your device.
- 🚀 Shamim – lightweight builds focused on the performance of old devices.
After downloading. APK-You need to install the file. When you first start, the application can request permissions to access the memory and microphone. If the application crashes immediately after opening, try clearing its cache in the application settings or find a version marked "stable".
Where to look for configuration files?
Manual installation of drivers and patches
For advanced users, there is a method of replacing the camera's system libraries, which requires root rights and recavers. TWRP. The essence of the method is to replace files libmmcamera_interface.so and other libraries from the folder /system/lib64/ modified versions.
This approach allows you to activate hidden sensor functions, such as recording video in 60 FPS or using a wide-angle lens (if it is physically present but software blocked).
| Library file | Location. | Function | Risk of substitution |
|---|---|---|---|
| libmmcamera_interface.so | /system/lib64/ | Camera control interface | Tall (black screen) |
| libcameracustom.so | /system/lib64/ | Sensor cadastral settings | Medium (artifacts) |
| camera.msm8937.so | /system/lib64/hw/ | HAL camera driver | Critical (bootloop) |
| libFaceBeautify.so | /system/lib64/ | Bitification algorithms | Low (no effect) |
If you're taking this step, make sure to back up /system through TWRP before making changes. Recovery from the backup is the only way to bring the phone back to life in case of an error. Don't try to modify these files through a file manager without superuser rights.
Set parameters for maximum quality
Once you install the new software, you need to adjust your shooting settings correctly. Redmi 8’s regular camera often has skin smoothing enabled by default, which “soaps” the image. Turn this effect off in the filter or AI settings menu to get a more detailed picture.
Turn on the framing grid and horizon level display. This will help kompon frame correctly, which is especially important for wide-angle shooting, where distortions around the edges can be noticeable. It is also recommended to set the maximum resolution available if you do not plan to do cropping.
For night photography, use a tripod or slam your phone against a stationary object. Even the best Night Mode algorithms require the device to be stationary for 2-4 seconds of exposure. Hands hold the phone perfectly is almost impossible.
⚠️ Attention: Using digital zoom on Redmi 8 severely degrades the quality, as it is just a trimming of the matrix. It is better to take a photo with maximum quality and then framing it in the gallery - the result will be similar, but with the option of choosing a composition after the fact.
Addressing common problems
A common problem after an update is the appearance of a black bar on the screen or complete dimming of the viewfinder. This indicates a resolution conflict or driver incompatibility. In this case, cleaning the data of the Camera application through the Settings menu → Apps → All applications → Camera → Clean will help.
If the camera is warming up and quickly depleting the battery, maybe the new photo processing process is too demanding for the processor. 1080p before 720p or disable geo-tag photos that are constantly polling GPS-module.
If you see artifacts (colored stripes) in the photo, check the physical condition of the camera plume. Software update will not fix the contact that has gone away. Carefully press the camera module on the back of the case; if the artifacts are missing, the hardware problem.
💡
Most camera software errors on Redmi 8 are solved by completely resetting the app settings or reinstalling it. APK-file with another version of Android SDK.
