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.
Samsung has announced the One UI 6 Watch Beta 4 update for Wear OS smartwatches. This update is available for the Galaxy Watch 6, Galaxy Watch 5, and Galaxy Watch 4 series. It includes several improvements based on user feedback to make your watch perform better and more reliably.

Furthermore, the update introduces Global Always-On Display (AOD) support to provide important information even when the screen is off.
The fourth beta update also contains a minor issue with the ‘Show last app’ setting. The default value has changed, which might affect users who previously set it to the ‘Not used’ or ‘Within 5 seconds’ option. If you notice that your setting isn’t being applied correctly, simply go to the Settings menu and select your preferred option to fix the problem.
Users of Galaxy Watch 6 series can verify the latest beta update through version ending with ZXG6, while Galaxy Watch 4 and Galaxy Watch 5 users are getting it with version ZXG7.
To install the update on your Galaxy Watch, go to Galaxy Wearable on your smartphone, then navigate to Galaxy Watch >> Watch settings >> Watch software update >> Download and install. This will allow you to install the latest beta version. Before updating, make sure to back up any important data on your watch.
Samsung Galaxy Tab S9, Galaxy Tab S9 Plus, and Galaxy Tab S9 Ultra users are getting a July 2024 security update in Canada. This update is already rolled out for users in Europe and the company will soon make it available in more countries.
The company is dispatching the latest software update with system security improvements to keep your files and data safe on your phone. It also optimizes system stability to offer you uninterrupted and seamless functionality on your device.
July 2024 update fixes over 55 issues including 4 critical and 21 high-level vulnerabilities in Android, contributing 33 SVEs related to components like One UI Home, System UI, Secure Folder, and more, further enhancing device security.
Users of the Samsung Galaxy Tab S9, Galaxy Tab S9 Plus, and Galaxy Tab S9 Ultra in Canada can verify the July 2024 security update through the One UI build version ending with BXCG. The installation package size of this update is around 358.38MB.
You can check the update by navigating to the device’s Settings, then a Software update, and Download and Install. If you have received the update, install it now to get enhanced features.
Samsung Galaxy Tab S9 users will soon get One UI 6.1.1 update with a bunch of new features. Some of the highlighted features are Sketch to Image, AI Portrait Studio, Auto Zoom, enhanced Note Assist, Instant Full-screen translation, conversation mode for dual screen, Suggested replies, Photo Ambient, and more.
One UI 7 could bring new battery indicator to Samsung Galaxy
Samsung has confirmed that it will fix an issue with the Home Up Finder feature through a new software update. Some Galaxy users have been facing an issue where the Finder’s layout does not appear correctly on their screens.
According to the information, the Finder sometimes overlaps with the battery, network, sound, and clock icons at the top of the screen. This overlap can hide the search field or make it difficult to use.
Users have reported that this issue makes it hard to search for apps or use the Finder effectively. Samsung has recognized this issue and is working on a solution. The community moderator has announced that the company will release a software update to fix the layout of the Finder feature of the Home Up.
Moreover, Samsung has also apologized for the inconvenience the Home Up Finder issue may have caused and ensures users that the company will fix it. Users should keep their devices updated by checking for new software updates regularly.
Previously, the company added the long-awaited ‘Access Finder’ feature that makes it easier for users to find and open apps quickly. In addition, users now have a new ‘App Icon Setting’ for the customization of app icons.
Several Galaxy users are facing the issue after using the Finder feature of the Home Up Good Lock module. Fortunately, the company has confirmed to solve it with the upcoming software update.
However, Samsung has not provided a specific timeline for when this issue will be resolved. Users will need to wait for future software updates and official announcements from Samsung regarding the Finder bug.
