One feature that has caught the attention of many is the red camera on the S21 Ultra. But what is the purpose of this red camera, and how does it enhance the overall camera experience? In this article, we will delve into the details of the red camera on the S21 Ultra and explore its features, benefits, and limitations.
What is the Red Camera on the S21 Ultra?
The red camera on the S21 Ultra is actually a Laser Autofocus sensor, which is a new addition to the Samsung Galaxy series. This sensor is designed to improve the autofocus performance of the camera, especially in low-light conditions. The laser autofocus sensor emits a laser beam that bounces off the subject, allowing the camera to quickly and accurately focus on the subject.
How Does the Laser Autofocus Sensor Work?
The laser autofocus sensor on the S21 Ultra uses a technology called Time-of-Flight (ToF) to measure the distance between the camera and the subject. Here’s how it works:
- The laser autofocus sensor emits a laser beam towards the subject.
- The laser beam bounces off the subject and returns to the sensor.
- The sensor measures the time it takes for the laser beam to return, which is called the “time-of-flight”.
- The camera uses this information to calculate the distance between the camera and the subject.
- The camera then adjusts the focus accordingly to ensure a sharp and clear image.
Benefits of the Laser Autofocus Sensor
The laser autofocus sensor on the S21 Ultra offers several benefits, including:
- Improved autofocus performance: The laser autofocus sensor allows the camera to quickly and accurately focus on the subject, even in low-light conditions.

What is the red camera on the S21 Ultra?
The red camera on the S21 Ultra is a feature that has been shrouded in mystery since the phone’s release. It is a small, red-colored sensor located next to the main camera lens on the back of the phone. This sensor is not a camera lens itself, but rather a laser autofocus sensor that helps the camera focus on subjects more quickly and accurately.
The red camera is a key component of the S21 Ultra’s advanced camera system, which includes a 108MP primary sensor, a 40MP front camera, and support for 8K video recording. The laser autofocus sensor works by emitting a beam of light that bounces off the subject being photographed, allowing the camera to calculate the distance and adjust the focus accordingly. This results in faster and more accurate autofocus, even in low-light conditions.
What is the purpose of the red camera on the S21 Ultra?
The primary purpose of the red camera on the S21 Ultra is to enhance the phone’s autofocus capabilities. By using a laser autofocus sensor, the camera can focus on subjects more quickly and accurately, even in low-light conditions. This is particularly useful for capturing sharp images of moving subjects or in situations where the lighting is poor.
In addition to improving autofocus, the red camera also helps to improve the overall camera experience on the S21 Ultra. By providing more accurate distance information, the camera can adjust the focus and exposure settings to capture the best possible image. This results in sharper, more detailed photos with better color accuracy and contrast.
Is the red camera on the S21 Ultra a new feature?
The red camera on the S21 Ultra is not a new feature, but rather an evolution of existing technology. Laser autofocus sensors have been used in cameras for several years, but the S21 Ultra’s implementation is more advanced and integrated into the phone’s camera system.
The use of a laser autofocus sensor on the S21 Ultra is a significant improvement over traditional autofocus methods, which rely on contrast detection or phase detection. The laser sensor provides more accurate distance information, allowing the camera to focus more quickly and accurately. This results in better image quality and a more responsive camera experience.
Can I use the red camera on the S21 Ultra for any other purpose?
The red camera on the S21 Ultra is primarily designed for autofocus and is not intended for use as a separate camera lens. However, some users have reported using the laser sensor to measure distances or detect objects in low-light conditions.
While these uses are not officially supported by Samsung, they do demonstrate the versatility of the laser autofocus sensor. However, it’s worth noting that the red camera is not a substitute for a dedicated distance-measuring device or a night vision camera. Its primary purpose is to enhance the phone’s autofocus capabilities and improve the overall camera experience.
Is the red camera on the S21 Ultra available on other Samsung phones?
The red camera on the S21 Ultra is a unique feature that is not available on all Samsung phones. While some other Samsung models may have similar autofocus capabilities, the S21 Ultra’s laser autofocus sensor is a distinct feature that sets it apart from other devices.
However, Samsung has used similar technology in other high-end phones, such as the Galaxy Note 20 Ultra. These phones may not have the exact same red camera feature, but they do offer advanced autofocus capabilities that are similar in functionality.
Can I disable the red camera on the S21 Ultra?
The red camera on the S21 Ultra is an integral part of the phone’s camera system and cannot be disabled. The laser autofocus sensor is always active when the camera is in use, and it provides critical distance information that helps the camera focus on subjects.
While some users may be concerned about the potential impact of the laser sensor on battery life or camera performance, Samsung has optimized the feature to minimize any negative effects. The red camera is designed to work seamlessly with the phone’s camera system, and disabling it would likely degrade the overall camera experience.
