How to pump the camera on Xiaomi Redmi Note 7: from basic settings to pro-chips

Xiaomi Redmi Note 7 is still one of the most popular budget smartphones with a good camera at 48 MP, but standard settings often do not reveal its potential. HDR-And you can, fortunately, fix this without buying a new phone, and you can set up the software, update the firmware, and use a few tricks.

In this article, 10 proven ways to improve the camera, from basic (which do not require root rights) to advanced (using custom GCam and manual settings). We will discuss how to deal with blur on the front camera in low light, why night shots come out green, and what settings are available. MIUI Camera should be turned off immediately. All methods have been tested on current versions of the software (including: MIUI 14 and HyperOS).

Important: results depend on the firmware version and the condition of the camera module. If the quality has not improved after all the manipulations, the problem may be in the hardware (for example, a contaminated lens or damaged sensor).

1. Update firmware and camera drivers

Xiaomi regularly releases updates for the Redmi Note 7 (codename lavender), which fixes camera bugs: improves HDR processing, reduces noise levels and optimizes autofocus. The latest stable version of MIUI for this model is V14.0.4.0.TFGMIXM (at the time of 2026).

How to update:

• 📱 Go to Settings. → The phone. → Updating the system.
• 🔄 Click “Check Updates” and wait for the search.
• 📥 If a new version is available, download and install (be sure to connect to Wi-Fi and charge your phone at least 50 times%).
• 🔧 After the update, reset the camera settings: Settings → Annexes → Application management → Camera. → Warehouse → Clear the data.

If there are no official updates, custom firmware can be installed (like LineageOS or Pixel Experience), but this requires unlocking the bootloader and may take away warranty — MIUI EU (European build without Chinese software, where the camera is more stable.

⚠️ Warning: When installing unofficial firmware, the risk of “bricking” the phone is ~5%. Always backup through TWRP before firmware and check the compatibility of the version with the Lavender model.

2. Optimization of standard camera settings

The MIUI Camera stock app hides a lot of useful options, and let’s look at the key settings that you should change:

1. Turn it off. AI-The algorithm often misbalances white, making the photos too warm or cold. → Settings (⚙) → AI-camera → Off.
2. Activate Ultra HD for the main camera. This allows you to shoot in full 48 MP (instead of 12 MP by default), but the files will weigh ~15-20 MB.
3. Set up. HDR. At Redmi Note. 7 eat 3 regime: 🌄 Automobile-HDR — It works unpredictable, it is better to disconnect. 🌅 HDR Always suitable for landscapes, but slows down shooting. 🌆 Off. - optimal for portraits and macro.

Set up a manual focus.

AF-L

For the front camera (13 MP), it is critical to turn off Beauty (even at a minimal level it blurs details) and turn on Portrait Mode with background blur - this will add depth to the pictures.

3.Install Google Camera (GCam) for better handling

Xiaomi's stock camera is losing out to Google Camera in color and detail processing. GCam is better at handling noise, retains natural skin tones and offers Night Sight mode, which is not found in MIUI Camera.

How to determine:

1. Download the latest stable version of GCam for lavender (recommended) BSG or Urnyx05). References: 🔗 BSG GCam 8.7 (best for Redmi Note 7). 🔗 Urnyx05 GCam 8.4 (more stable but without some features).

Recommended GCam settings:

⚠️ Warning: Some versions of GCam may cause green tint in night shots. If this happens, try turning off Night Sight or install a different build.

💡

Before shooting in GCam, clear the app's cache (Settings → Apps → Google Camera → Storage → Clear the cache).

4. Manual control of the shooting parameters

For full control of the camera, use Pro mode (in the standard app) or third-party programs like Open Camera or Manual Camera.

• 📸 Extract: Use static objects 1/10–1/30 c. for movement — 1/250 c and shorter).
• 🌡️ ISO: During the day – 100-200, at dusk – 400-800, at night – 1600-3200 (but expect noises).
• 🎯 Focus: For macro, use manual focus 5–10 cm from the lens.
• 🔄 White balance: 5000K natural-light, 3500K — filament lamp.

Example of settings for portrait photography in the room:

• Shutter speed: 1/60 s
• ISO: 400
• Focal Distance: 2.0x zoom (for background blur)
• White balance: 4500K

For nighttime shooting without GCam:

• Use a tripod or support (even a small shaking will ruin the picture).
• Set shutter speeds of 1-2 s and ISO 1600.
• Turn off the flash, it only spoils the colors.

5. Cleaning the lens and checking the hardware

Often, poor photo quality is not related to the software, but to the physical condition of the camera. Dust, fingerprints or scratches on the lens can cause blurring, glare and reduced contrast.

1. Take a look at the lens. Hold the phone to a bright light source -- there should be no stains, scratches, or stains on the lens. Use a microfibre wipe (not paper!) and 70% isopropyl alcohol (apply to a napkin, not the lens!) to clean the lens.
2. Check autofocus. Switch to Pro mode, point the camera at an object ~30 cm away, and tap the screen. If the focus is floating or not fixing, the focus motor may malfunction.
3. Overheating test. Take 10 photos in a row in 48 MP mode. If the camera starts to "lag" or gives an error "Camera overheated", a replacement of the thermal paste is required (relevant for phones older than 3 years).

If you have problems after cleaning, check the camera through the engineering menu:

1. In the phone app, dial the code ##4636##.
2. Select Testing → Camera.
3. Run the Front Camera and Back Camera tests, and if E: Camera open failed errors appear in the logs, it indicates hardware failure.

⚠️ Warning: If the main camera shows a green or purple screen in the engineering menu test, the sensor is damaged, in which case only a replacement module (cost) will help. ~2 500–3 500 ₽ service-centre).

6.Use of third-party applications for post-processing

Even with perfect settings, Redmi Note 7 images often require rework.

• 📷 Snapseed is a free editor from Google with Selective (tone correction of individual zones) and Healing (spot removal) tools).
• 🎨 Lightroom Mobile - professional color correction with presets. For Redmi Note 7, presets with settings will suit: Contrast: +20 Shadows: +30 Clearness: +15 Noise suppression: +25 (for night photos)
• 🔍 Topaz Gigapixel AI — Plugin to increase resolution (useful for 12 MP images that need to be printed).

Typical edits for photos with Redmi Note 7:

💡

For selfies with Redmi Note 7, always shoot in RAW format (if supported in GCam) – this will give you more data to post-process.

7. Alternative ways to improve the camera

If standard methods don’t help, try:

• 🔧 Retrace to the old version MIUI Camera. In some updates, Xiaomi is corrupting processing algorithms. MIUI 12.5 The camera worked better than the camera MIUI 14.The application version can be downloaded from APKMirror.
• 📱 Using an external camera. USB-C OTG Redmi Note 7 can be connected to DSLR-The camera (such as Sony Alpha) and control it through apps like DSLR Controller.
• 🔄 Calibration of the light sensor: If the camera is constantly under-lighting or over-lighting, try calibrating the sensor through the engineering menu (#36446337## → Light Sensor).

For experimenters, modified camera firmware (such as the ANX Camera or the Footij Camera) offers advanced settings, but requires root rights and can conflict with the system.

8. Frequent mistakes and how to avoid them

Even after all the settings, users make mistakes that spoil the photo.-5:

1. Shoot against light. If the light source (the sun, the lamp) is behind the object, turn on the HDR or change the angle, otherwise the object will become a silhouette.
2. Using digital zoom, when you zoom in over 2x, the quality drops dramatically, so you better come closer or cut the photolater.
3. It's HEIF, which saves space, but many editors don't support it. Switch to JPEG in the camera settings.
4. Ignore the rule of thirds. Turn on the grid (Settings → Camera → Grid) and place key objects at the intersection of the lines.
5. Photo storage on a memory card: The speed of writing on a microSD is often lower than in internal memory, which can save photos with artifacts.

💡

Before an important shot (such as an event), take test shots in different modes, which will help to avoid unpleasant surprises.
