Wide-angle camera on Redmi Note 9 Pro: how to turn on and configure correctly

Why a wide-angle camera may not work – and how to fix it

Owners of the Xiaomi Redmi Note 9 Pro often face a situation where an additional 8-MP wide-angle camera (with a focal length of 118°) is either missing from the Camera application interface or gives an error when trying to shoot. The reasons range from software failures to hardware limitations - for example, after updating MIUI or resetting. In this article, we will discuss all the working methods of activating the module, including hidden settings and workarounds for different versions of the firmware.

It's important to understand that the wide-angle camera on the Redmi Note 9 Pro (model joyeuse) is physically present in 99% of devices, but it depends on the MIUI version and regional settings. For example, in firmware for India or China, the module may be disabled by default due to local certification requirements. We tested all methods on MIUI 12.5-14.0 - the results are summarized in the table below.

Hardware Compatibility Check: Is There a Camera in Your Smartphone?

Before you try to turn on a wide-angle camera, make sure it is physically installed in your device.

• 🔍 Go to Settings. → The phone. → Version. MIUI and tap 7 times on the kernel line to activate the developer mode.
• 📱 Back to Settings → Additionally. → For developers and enable the debugging option USB.
• 💻 Connect the phone to the PC, open the command line and type: adb shell dumpsys media.camera logical_camera_id: 2 — This is the wide-angle module.

If commands output does not mention the second or third module (besides the main and front), then your device is complete without a wide-angle camera, which occurs in rare batches for some regions (for example, the Redmi Note 9S for Latin America), in which case the further actions are meaningless - the module is not physically present.

Method 1: Enable via the standard Camera app

In most cases, the wide-angle camera is hidden in the application interface, so you can activate it.

1. Open the Camera app and go to Photo mode.
2. Touch the 0.6x (or WIDE) icon in the top toolbar. If it's not there, swipe your finger across the screen from left to right to open the modes bar.
3. If the icon is missing, tap on ⚙️ Settings → Additionally. → Show a wide-angle camera.

On MIUI 13+ firmware, the path may differ: Camera settings → Modes → Wide-angle objectiv. If the option is inactive, then you need to reset your camera settings (see next section).

Update the Camera app to the latest version on Google Play

Clear the app cache in Settings → Apps → Camera → Memory

Restart your phone after cleaning.

Check for updates MIUI In Settings → The phone.-->

Method 2: Reset camera settings and clear cache

If the wide-angle camera was working before, but suddenly disappeared, the problem lies in the damaged application data.

1. Go to Settings → Applications → Application Management → Camera.
2. Click Memory → Clear the cache and Clear the data.
3. Return to Settings → System → Settings Reset → App Resets (this won’t delete your photos!).
4. Restart the phone and check the camera.

Critical detail: Once the camera settings are reset, all user presets (such as manual ISO or white balance settings) will be lost.

💡

If you don't have a wide-angle camera after reset, try installing an alternative shooting app like GCam (Google Camera) with support modules. Links to the proven versions for the Redmi Note 9 Pro are on the official Xiaomi Fans Telegram channel.

Method 3: Activate through the Engineering Menu (for advanced users)

If standard methods don't work, you can try turning the camera on through the Engineering Menu (CIT), which requires caution - wrong actions can cause the camera to crash!

1. Open the Phone app and type in the combination: ##36446337## (or #4636## → go to Hardware Testing).
2. Choose a Single Camera → Camera2.
3. In the module list, find Ultra Wide (or Camera ID: 2) and click Open.
4. If the camera is open, but it is not in the standard application, then the problem is in the firmware (see Method 4).

⚠️ Note: Do not change other options in the engineering menu, especially those related to the OTP Or Calibration. This can cause permanent damage to the camera.

Method 4: Install custom firmware or ported "Camera"

If the wide-angle camera is locked at the firmware level (e.g. in regional MIUI versions for the EU), you will need to:

1. Install global firmware via Fastboot or Recovery: 🌍 MIUI Global 14.0.2 (stable) 🧪 MIUI EU 13.0.6 (unofficial, with unlocked functions)

Use the modified Camera application

• 📷 ANX Camera (with support for auxiliary modules)
• 🔍 Footiej Cam (for manual wide-angle camera activation)

Fastboot firmware requires an unlocked bootloader.Instructions for unlocking the Redmi Note 9 Pro:

fastboot oem unlock

Frequent problems and their solutions

Even after successful activation, the wide-angle camera may not work properly. Consider the typical errors and ways to fix them:

• 🔴 Mistake: “I failed to connect to the camera» → Restart your phone and check if the camera is busy with another app (like WhatsApp or Snapchat).
• 🟡 Image green/purple → This is a hardware defect in the module. ~1 500–2 000 ₽).
• 🖼️ Severe distortion at the edges (fish eye effect») → Enable distortion correction in camera settings (Settings) → Additionally. → Wide-angle lens correction).

⚠️ Note: If after the update MIUI Wide-angle camera stopped working, don't rush to drop your phone. First check if the module is off in Settings → Annexes → Permits → System process camera (e.g. com.miui.camera).

If none of the methods worked, check the phone for hardware defects. The wide-angle camera on the Redmi Note 9 Pro connects through a separate plume - its damage or oxidation of the contacts can lead to a complete failure of the module.
