How to update the camera on Xiaomi Redmi Note 7: all ways and life hacks

The Xiaomi Redmi Note 7 is still a popular smartphone due to its price-performance balance, but over time, the camera can start to perform worse: dim shots, slow focus or app errors. Updating the camera is not only about installing a new firmware, but also optimizing settings, replacing software or even upgrading hardware (for the module).

It's important to understand that the term "update camera" can mean different things. For some, it's a firmware upgrade through MIUI, for others, an upgraded Google Camera (GCam), and for some, a physical replacement of the module with a more modern one. We'll look at all the options, including the risks and nuances of each method. If your goal is to just improve the quality of the photo without the risk of "bricking" the phone, start with the first two sections. For experienced users, instructions on custom firmware and modifications.

Before you start, check the current version of the software: go to Settings → About Phone → MIUI version. If your firmware is older than MIUI 12.5, the official update can significantly improve the camera performance without additional manipulation.

1. Official MIUI Update: An Easy Way to Improve Your Camera

The safest method is to upgrade the Redmi Note 7 to the latest MIUI through built-in settings. The manufacturer regularly optimizes image processing algorithms, fixes autofocus bugs, and adds new features (like night mode or improved HDR).

Open Settings → About Phone → System Update. If a new version is available, download it (preferably via Wi-Fi, as files weigh 1.5-2.5 GB). Make sure that the battery is at least 50% - when the discharge during the upgrade, the phone can go to fastboot and require manual recovery.

• 🔄 Automatic Update: Enable the “Outload” option in the update settings to avoid missing new versions.
• 📥 Manual check: click “Check Updates” – sometimes Xiaomi servers do not issue updates immediately for all regions.
• 🔋 Charging is mandatory: if the charge is below 30%, the system will block the installation.
• 🌐 ROM ROMWORK: If your Redmi Note 7 is purchased in China, updates to the global version (MIUI Global) may not be displayed.

After upgrading to MIUI 13+, Redmi Note 7 will feature Document 2.0 mode with improved text processing and PDF scanning, and fixes a bug with a pink tint in low-light photos that was relevant for early firmware versions.

⚠️ Warning: If after the update the camera started to issue an error "Can not connect to the camera", reset the settings of the application: Settings → Annexes → Camera. → Warehouse → Clear the data. It will delete the user's settings, but it will bring back the functionality.

2.Install Google Camera (GCam): revolution in photo quality

The stock camera app on the Redmi Note 7 often loses Google Camera in detail, HDR processing and night shooting. GCam uses HDR+ and Night Sight algorithms that outperform Xiaomi’s standard solutions.

1. Download a compatible version of GCam (e.g. BSG or Urnyx05 for Snapdragon 660).
2. Enable installation from unknown sources: Settings → Applications → Special Access → Installation of unknown applications.
3. Set up XML-Config (camera profile) under Redmi Note 7.

There are no official sources, but the verified versions are published on the XDA Developers forums or in telegram channels (for example, @gcammods). Note the CPU version: Redmi Note 7 runs on the Snapdragon 660, so GCam for the Snapdragon 8xxx will not work.

• 📸 Night Sight: Night photos become brighter and more detailed (example: comparison of stock camera and GCam).
• 🎯 Autofocus: GCam catches focus faster in low light conditions.
• 🔍 Super Resolution: Increase without loss of quality (useful for shooting remote objects).
• ⚙️ Manual settings: available ISO, shutter speed, white balance (in the stock camera these options are limited).

⚠️ Note: Some versions of GCam can cause the processor to overheat when shooting long-term video in the video 4K. If the phone starts to brake, limit the resolution of the video to 1080p GCam settings.

💡

Before installing GCam, back up your photos and videos – some versions of the app may conflict with the stock gallery and result in the loss of thumbnails.

3.Castom firmware: full control of the camera

If the official updates and GCam don’t work, custom firmware (such as LineageOS, Pixel Experience or HavocOS) can be installed.

• 📱 More recent versions of Android (for example, Android 12 instead of Android 10 in stock). MIUI).
• 🔧 Advanced camera settings (manual noise reduction adjustment, video bitrate).
• 🚀 Improved performance through an optimized core.

However, the installation process requires unlocking the bootloader and can result in a loss of warranty.

Unlock the bootloader through Mi Unlock Tool|

Install custom recovery (TWRP) |

Download firmware and GApps (if you need Google services)|

Make a backup of data (photos, contacts, SMS) |

Charge the phone to 100%-->

After installing custom firmware, the camera can work better due to:

1. Updated drivers (e.g., Pixel Experience uses a Google Pixel camera).
2. No MIUI limitations (no artificial quality degradation on budget models).
3. Camera2 API support (full access to manual settings for applications like Open Camera)

⚠️ Attention: Custom firmware may not have a wide-angle module (second lens) due to lack of drivers. 4PDA or XDA.

4. Hardware Update: Replacement of Camera Module

If software methods don’t work, you can physically replace the camera module with a more modern one, for example, some users install a camera from the Redmi Note 8 Pro (with a Samsung GW1 64 MP sensor) instead of the standard Sony IMX486 48 MP.

• 🛠️ Soldering works (replacement of the plume and soldering of contacts).
• 📏 Precise fit (modules may vary in size).
• 💻 Firmware corrections (for the correct operation of the new sensor).

The cost of this upgrade is between 3,000 and 8,000 rubles (depending on the donor module and workshop), resulting in improved detail, dynamic range and focus speed, but the warranty on the phone will be lost, and the risk of damage to the ration board is high.

💡

Replacing the camera module is an extreme method, and 90% of the time, you can improve the quality of the photo software (GCam, custom firmware).

5. Optimization of camera settings without firmware

If you don’t want to take risks but want to make the most of your current camera, try these settings:

• 📷 Photo resolution: set 48 MP (in camera settings) instead of the default 12 MP. This will increase detail, but the files will weigh more.
• 🌓 Night mode: turn it on manually even during the day - algorithm MIUI Sometimes it is better to handle the shadows.
• 🎞️ Video Stabilization: Activate EIS (Electronic stabilization in video settings.
• 🔍 Manual Focus: In Pro Mode, set the focus to infinity for macro photography.

It's also helpful to turn off AI-Improvements (option «AI Despite Xiaomi's promises, the algorithm often overdoses the processing, making the colors unnatural. HDR without AI.

💡

If the camera is slowly focusing, clean the lens of dust with a soft brush, often the problem is not the software, but the physical contamination of the lenses.

6. Solving Common Camera Errors

If the camera on the Redmi Note 7 is making errors, try these solutions:

If the error persists after all the manipulations, try resetting your phone to factory settings (don’t forget to back up!). In 10% of cases, the problem lies in a corrupted system file, and only a full reset helps to return to work.

7. Alternative camera applications

Besides GCam, there are other apps that can improve shooting on the Redmi Note 7:

• 📸 Open Camera: Open source, support Camera2 API, manual.
• 🎥 Footage: professional video with bitrate and codec management.
• 🌃 Night Camera: Specialized night mode for weak sensors.
• 📐 Manual Camera: Full control of the camera ISO, sensing, focus (requires) Camera2 API).

When choosing an application, pay attention to support Camera2 API — Without it, many functions (such as manual focusing) will not be available. Camera2 API Probe from Google Play.
