Xiaomi Redmi Note 8 Pro has come to market as the “king of the mid-range,” offering users an impressive set of specs for an affordable price. One of the key elements that attract attention when buying was the front camera hidden in the screen notch.
Many owners still wonder what this top camera is designed for and what unique features it hides behind the standard video link feature? In this article, we will examine in detail the hardware, software algorithms and hidden features of the module that turn a regular selfie into a quality shot.
Understanding the principles of this component will allow you to squeeze the most out of the device, using it not just as a means for making calls over video, but as a full-fledged tool for creating content.
Technical characteristics of the module: what is inside
The front-facing system is based on a 20 megapixel sensor, which is not just a marketing figure, but a real-world physical parameter that captures a huge amount of detail even when you frame an image, and it has a pixel size of 0.9 microns, which is standard for devices in this price segment.
The camera lens has a light force of f/2.0. This parameter is critical for the amount of light that hits the matrix. The smaller the aperture number, the better the camera copes with the conditions of insufficient light, although in the case of a front camera, you can expect the wonders of night shooting still not without the help of software algorithms.
The important feature is fixed focus, which doesn't have a classic AF system, because it's designed to capture objects at arm's length, but Xiaomi's current algorithms have successfully compensated for this with software.
- 📷 The resolution of the matrix is 20 MP, which provides high detail.
- 💡 The light of the lens f/2.0 Allows you to take pictures in medium light.
- 📐 The focal length is equivalent to 27 mm, which is ideal for portraits.
- 🎥 Support for video recording in resolution 1080p 30 frames per second.
It's worth noting that software processing plays an even bigger role here than hardware. Beautify's AI algorithms work in real time, analyzing the face and applying settings.
Main purpose: video and selfie
The primary and most obvious function of the top camera is to provide video communication, and because of its position at the top of the screen, the camera minimizes the overlap of the user's face during a conversation, which is especially true when using applications like Zoom, Skype or Telegram.
The video quality is optimized for 4G and Wi-Fi networks. The system dynamically adjusts bitrate to avoid connection breaks even if the signal is unstable. For bloggers, this means that live streaming is possible in acceptable quality without the use of additional equipment.
In photography mode, the camera offers a wide range of settings. You can switch between standard mode and portrait mode. In the latter case, software blurring of the background is used, which emulates the bokeh effect characteristic of expensive SLR cameras with aperture optics.
⚠️ Attention: The background blur effect (boke) is software-based and may not work properly with curly hair or complex objects in the background, creating artifacts.
To improve the quality of the selfie in the camera settings, you can activate the function “Portrait Improvement”, which smooths the skin, adjusts the tone of the face and can even visually change the shape of the face, making it narrower or wider at the request of the user.
Shooting modes and artificial intelligence
Xiaomi’s modern smartphones are equipped with powerful neural networks that process every frame. The top camera of the Redmi Note 8 Pro is no exception. AI algorithms recognize a scene and a person’s face, automatically selecting optimal parameters of exposure and white balance.
One of the key features is Portrait AI mode, where unlike standard blur, the system builds a deep map of the image, separating the subject from the background with high accuracy, which allows you to apply various studio lighting effects at the time of shooting.
Night Mode is also available for the front camera, and it works on the principle of a series of images: the camera takes several frames with different exposures in a fraction of a second, and then programmatically combines them to remove digital noise and increase brightness.
- 🌙 Night mode significantly reduces the level of digital noise in low light.
- 🎨 Live photo filters add dynamics to static images.
- 👤 Gender and age recognition for fine-tuning retouching.
- ✨ The Magic of Color mode allows you to leave only the subject of the shooting colored.
It’s important to understand that activating all of these functions requires the processing power of the processor, so with power saving mode on, some AI functions may be limited to the system to save battery life.

To get the most natural skin color in the room, try to stand facing a light source (window or lamp), avoiding the top directional light that creates shadows under the eyes.
Comparison with the main camera: is there a difference
Often users compare the front and main camera capabilities, expecting the same quality. But the physics of the process dictates its conditions. The main camera of the Redmi Note 8 Pro is equipped with a 64 MP sensor Sony IMX686, which is radically different from the 20 MP module Samsung S5K3P9 mounted on the front.
The difference is not only the number of megapixels, but also the size of the matrix, the light strength of the lens and the presence of optical stabilization (OIS) on the main module.The front camera lacks optical stabilization, relying solely on electronic (EIS) when recording video.
However, for social media, where images are often compressed, the difference of 20 MP and 64 MP may not be as noticeable on the smartphone screen.The main advantage of the main camera is versatility and work in extremely low light, where the front just "blinds."
| Characteristics | Front camera. | Main camera. |
|---|---|---|
| Permission | 20 MP | 64 MP |
| Diaphragm | f/2.0 | f/1.8 |
| Pixel size | 0.9 μm | 0.8 μm (with binning 1.6 μm) |
| Stabilization | Electronic (EIS) | Optical + Electronic |
| Video | 1080p @ 30fps | 4K @ 30fps |
The table shows that the front camera is a compromise solution aimed at video communication and quick selfies, while the main camera is designed for full-fledged photography.
Hidden functions and interface settings
The MiUI camera interface hides some useful features that not everyone knows about, such as gesture control, which allows you to take a picture by showing your palm to the camera, which is especially convenient when the phone is mounted on a tripod or you hold it on your outstretched arm.
You can find the "Mirror Reflection" option in the settings, and by default, the front camera shows the image as if it were in a mirror, which is familiar to the user, but the text on the clothes or background reads the other way around, and turning on this option makes the photo realistic for an outside observer.
Another important setup is speed or quality, and if you're shooting moving objects or children, you better prioritize speed to avoid lubrication, and you prefer quality mode for static portraits.
⚠️ Note: The inclusion of the "Mirror Reflection" function applies only to the preview and the final photo, but does not affect the image in the video mode of messengers, since it uses the system data stream.
It’s also worth mentioning the possibility of shooting in RAW format through third-party applications (such as GCam), although Xiaomi’s regular software doesn’t provide this capability for the front-facing camera directly, giving enthusiasts more freedom in post-processing.

Frequent problems and ways to solve them
Despite the reliability of the module, users can experience software failures, the most common problem is a black screen when you start the camera application or an error message saying “failed to connect to the camera”, often solved by simply restarting the device.
If the problem persists, a third-party app using camera access may conflict. Check the permissions in the Settings menu → Apps → All apps. Make sure no program uses the camera in the background.
In some cases, cleaning the Camera app cache helps. Go to Settings → Apps → Camera → Memory → Clean. This won’t delete your photos, but will reset the app itself to the factory settings.
A more rare but possible problem is the appearance of stripes or artifacts in the image, which may indicate physical damage to the plume or oxidation of contacts, especially if the phone has previously come into contact with moisture.
- 🔄 Rebooting the smartphone solves 80% of software errors.
- 🧹 Cleaning the lens with an alcohol napkin improves sharpness.
- ⚙️ Resetting camera settings through the app menu eliminates interface glitches.
- 📱 Firmware update MIUI Often contains corrections to the camera module.
If software methods do not help, and the camera emits extraneous sounds or warms up in the area of the module, it is recommended to contact the service center for hardware diagnostics.

Tips for the Perfect Selfie on the Redmi Note 8 Pro
To get the most out of your top camera, follow a few simple guidelines: First, always keep your lens clean. Fat spots from your fingers are the main reason for cloudy glare shots.
Second, use natural light, face the window, but not the direct sunlight, to avoid the overlights, and the soft diffuse light is the best way to hide skin flaws and highlight details.
Third, experiment with angles. Hold the phone just above eye level and tilt it down a little bit. It visually lengthens the neck and makes the eyes expressive. Don't be afraid to use a timer to put the phone on a steady surface and free your hands.
⚠️ Attention: Using a digital zoom tweak on the front camera dramatically reduces image quality, as it is just software cropping, not an optical approximation.
Remember that the best quality of images on the Redmi Note 8 Pro is achieved in 4:3 daylight without the use of heavy filters that can hide details.
💡
The main secret of high-quality photos from the front camera is a clean lens and the right light, not just the settings of the smartphone itself.
