Let’s talk about the Galaxy HDR technology implemented in the Galaxy S23 series. But do you know what HDR is? If you do not know, then let us tell you that HDR (High Dynamic Range) is a technology that expresses bright and dark areas as widely as possible.

When we take pictures or videos, we get images with suitable brightness through AE (Auto Exposure) operation which adjusts the exposure. However, when shooting indoors in backlit conditions or while looking out a window, bright and dark scenes coexist, resulting in images that are bright or dark depending on the scene.

Samsung Galaxy S23 HDR Technology

In Samsung Galaxy S23, the company uses the MF-HDR (Multiple Frame HDR) compositing method. It is a technology that takes pictures of different brightness by continuously adjusting the exposure, and then extracts the video information of the bright part from the bright picture and the video information of the dark part from the dark picture, and combines them into one picture.

Since the image is created by selectively combining bright and dark object information, an image with optimal brightness is created. However, since MF-HDR captures multiple consecutive scenes, there is a lag between scenes.

It means that a moving subject is prone to ghosting when the motion vector and image overlap, so it is recommended to use it in a shooting mode where the subject moves little.

On the flip side,  in motion picture mode, SF-HDR (single-frame HDR) technology is applied, and image sensor IDCG (Intrascene Dual Coverage Gain) technology is used to capture and synthesize bright and dark scenes simultaneously.

Image sensor iDCG technology generates electrons, that is, electrical signals, according to the brightness when light is incident on the photodiode of the image sensor, and the image sensor’s internal circuit (ADC: Analog Digital Converter and Logic Circuit) is used to convert the image sensor does for voltage. It goes through a process of change.

During the conversion of light into an electrical signal, electrons are placed in a cup called FD (Floating Diffusion) to measure the number of electrons. Determine a specific ratio based on the capacity of the cup and convert it to a voltage signal.

In the case of existing sensors, the capacity of the cup is limited to one, so it is difficult to take great pictures in environments with frequent changes in light and dark.

If the cup potential is large in a dark environment, it will be difficult to clearly express the dark part because the small light information cannot be converted into a sufficient voltage. It’s hard to articulate the bright parts well.

iDCG technology converts the existing one cup into two cups of different capacities, selects the smaller cup in a dark environment, selects the larger cup in a bright environment, measures twice, synthesizes in real-time, and HDR improves the performance of the image.

In the case of SF-HDR using 1 exposure, it is better for shooting moving images than MF-HDR using 2 exposures because of the sharpness of the subject’s movement. In addition to this, the company is preparing to bring HDR performance closer to the human eye through camera image sensors and ISP technology.

Here’s how the Samsung Galaxy S23 series’ distinct design came about:

Design theme – “Create the Essentials”

If too many unnecessary details are incorporated, resources can be wasted during the production process, so Samsung Galaxy S23 creators decided to retain only the bare essential design features, based on the true identity of the device.

The Samsung Galaxy S series is a product lineup built on the true essence of what premium design can be. For the Galaxy S23 series, we deliberated extensively on what elements would not only make for a great design but also how they would impact the world at large.

Signature design

Vanilla and Plus Galaxy S23 variants introduce thin bezels that are slim and balanced on all sides for users to better focus on their screens, while a curved metal frame both protects the screen and provides the user with a comfortable grip.

Adding to this, the camera contour cut design seen on the last year’s Galaxy S22 and S22+ was removed, and all three models of the Galaxy S23 series are now equipped with a single camera design to deliver even more consistency across the lineup.

The Galaxy S23 Ultra brings reduced side edges and extended flat surfaces even further. It not only provides a better grip but also provides more space in which the S Pen can be utilized and ultimately maximize the benefits of the large screen.

Camera’s distinct design

Samsung believes the camera design of a device has become a powerful way to distinguish a product and express brand identity. The Galaxy S23 series camera layout has stayed the same since the Galaxy S21 series in order to foster a unique design identity.

Meanwhile, the external part of the camera is a glossy metal while the internal parts have been processed with smooth hairlines to convey the camera’s powerful performance. The design of the inner elements, including the form, texture, and color, is inspired by traditional camera lenses.

Colors are inspired by nature

The Galaxy S23 series comes in four colors that are based on a concept Samsung calls “Shades of Nature”. The Green shade is reminiscent of a tranquil forest while Phantom Black embodies the silent strength of nature, and the bright Cream shade is warming to look at while Lavender captures the energetic nature of everyday life.

Besides, the company developed four additional colors under the concept of “Shades in Dream”. Exclusively available on Samsung.com, the Lime, Skyblue, Red, and Graphite provide online customers with some upbeat and futuristic shades.

You can read the entire design story at Samsung Newsroom.

At the Mobile World Congress 2023 event in Barcelona, T-Mobile announced the perfection of 5G carrier aggregation on its standalone 5G network. The company said it collaborated with Samsung, Ericsson, Nokia, Qualcomm Technologies, and Inc. to execute the technology.

Samsung’s Galaxy S23 phone was used for the project, which aggregated four channels of the mid-band spectrum on its 5G standalone (5G SA) network. The Un-carrier also expanded VoNR to four new cities, including Cincinnati, OH; New Orleans, LA; New York, NY; and Seattle, WA.

5G standalone is the future of wireless, providing a new level of performance, faster speeds, and better response times. Meanwhile, 5G carrier aggregation allows T-Mobile to turbo-charge 5G SA speeds to deliver game-changing performance to the customers while VoNR ensures seamless 5G SA connections.

In the keynote at Mobile World Congress, T-Mobile further explained how the company is taking its nationwide 5G SA network. At the same time, it announced that T-Mobile achieved the world’s first four-carrier aggregation data call on its 5G SA network with a commercial device, reaching speeds above 3.3 Gbps.

Additionally, the Un-carrier has deployed VoNR service in four additional cities and plans to cover 100 million people with VoNR in the coming months.

Moreover, the Samsung Galaxy S23, S23+, and S23 Ultra customers using the T-Mobile network will be among the first to experience four-carrier aggregation later this year. On the other side, the advanced 5G speed will further expand to more devices.

Samsung has already arranged a virtual power key on the quick panel. Alternatively, you can also turn off the phone by pressing the side key and volume down combination. Furthermore, you have the option to say “Turn off the phone” Bixby voice command to shut down the device.

Controversial Side Key:

The history of Samsung’s power key and its controversy is not unknown to the people who owned a Samsung Galaxy S8 or later device. For starters, the Galaxy S8 and the following models dedicated the physical side key to a Bixy trigger.

This change caused mayhem among consumers, as the key was pressed accidentally, and each time, it was causing a disturbance in the user experience. After feedback, Samsung rolled out a Bixby update that allowed them to trigger Bixby on double press.

After a year, Samsung stepped backward and launched a feature to freely customize the power key to assign both double press and press and hold features.
