Here’s how Galaxy HDR works on the latest Samsung Galaxy S23
Samsung Galaxy S23 series comes with a new design, new features, and the latest software. In addition, the Galaxy S23 series shows Samsung’s groundbreaking photographic capabilities such as stand-out selfies, cinematic video with less noise even in dark conditions, Auto Exposure with HDR, detailed photos, and more.
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.
Back in April, Samsung announced that the Samsung Free platform will be replaced with Samsung News. Following the announcement, the company released the Samsung News service in the US as part of the Beta trial, which is now readying for expansion, starting with Europe.

According to the information, Samsung filed a new trademark application at EUIPO (European Union Intellectual Property Office), which reveals that the company is preparing to expand the market availability of the new News aggregation platform, including Europe.
Along with the trademark application, the South Korean tech giant has mentioned the new icon displaying Samsung News. The “Goods and Services” section describes “computer software for users to share daily information to provide interactive and personalized intelligence.”

Samsung offers one of the better ways to understand your overall health is in your body composition. On your Samsung Galaxy Watch 5, you can easily use the Body composition feature.
Knowing about your body composition can tell you whether your body fat percentage is within a healthy range. Through this, you’ll learn how to make the right changes to achieve your physical goals and reduce your risk of diseases like heart disease, diabetes, and high cholesterol in the long run.
There are many ways to measure your body composition, but some can be expensive, not generally available to the public, or simply impractical, while others can be error-prone if done incorrectly. If you juggle a busy schedule and are always on the go, but want to maintain a healthy body, you may need options that fit your lifestyle.
So Samsung says hello to BIA. It stands for Bioelectrical Impedance Analysis is a method of estimating your body composition by sending small electric currents (completely painless) throughout your body to see how easily they pass through your tissues. The voltage is measured to calculate the impedance (resistance) of the body. Most body water is stored in muscles, so if a person is muscular, that person also has more water in their body, resulting in lower impedance.
This method is simple, cheap, fast, and non-invasive. No need to buy expensive devices as the BIA sensor is available in affordable devices like Samsung Galaxy Watch 5 and Galaxy Watch 5 Pro.
With the Body Composition feature on Samsung Galaxy Watch 5 series, you can take measurements on the go. Still, the company recommends regular visits to your doctor for standard health checks.
Not only that, but you can also log your results on the Samsung Health app. It’s great when you can track your progress toward sound health. The app also provides suggestions on how to improve your diet or exercise routine to achieve your physical goals. In addition, when you connect the watch to the Samsung Health app, it gives you even more value, like sleep, stress, blood pressure, ECG, and more.
Are you also suddenly facing Internet or Wi-Fi connectivity issues on your Samsung smartphone? If this is the case, then let us tell you that many times some such functions are enabled in our smartphones due to which issues start occurring.
If you are also facing Internet connectivity issues in your Samsung smartphone, one of the reasons could be the private DNS function. If you enter and use a specific Private DNS provider hostname, the Internet/Data/Wi-Fi (Wi-Fi) connection may become unavailable or slow, depending on the location of the DNS servers.
The network error occurs if you have installed the app and entered a private DNS provider host to block ads. The problem can be rectified by disabling the previously set private DNS.

How to Disable Private DNS?
You can easily disable the Private DNS function by following a few steps mentioned below.
- Open the Settings app on your Galaxy smartphone.
- Click on the Connections option.
- Scroll down and tap on More connection settings.
- Now, tap on the Private DNS option.
- Once you tap on the function, you can see three options.
1) Off
2) Automatic
3) Private DNS provider hostname
- You just need to select the ‘Off ‘option and click on the Save option.
