Earlier, it was reported that the SoC area is 30% larger than the Exynos 2200, about 130 square mm, similar to the Apple M1. For now, the chip allegedly had to downclock the Cortex-X4 core, but this may change in mass production.
Besides, there is also rumored that the company’s upcoming flagship SoC, the Exynos 2400, would use Samsung’s 4LPP+ manufacturing process, as well as AI performance is expected to be 44 TOPS.
Recently, it was reported that Samsung Mobile Head TM Roh conducted a thorough review of the Exynos 2400 and gave the green signal to the mass production plan, which will start around November 2023.
A recent report also claimed that the Exynos 2400 would make its debut with the vanilla Galaxy S24 model next year. The company won’t take any risky decision by widely using the Exynos chipset, hence, Plus and Ultra will continue to feature the next Snapdragon chip.

Recently, a user-generated Reddit post has become a controversial thread, claiming that Samsung is cheating with Space Zoom and the Moon shots by using AI. The user used an image of the Moon, went some steps backward, and captured the displayed Moon to check what happens.
Samsung Galaxy Camera uses AI to upscale the image of the Moon so it looks clearer in images. To do so, the company has applied an intelligent method, which consists of shots of a real Moon in all of its shapes. Machine learning helps the shot to be nourished further during processing.
In his Reddit post, the user said that he has downloaded a high-resolution image of the Moon from the internet, downscaled it to 170×170 pixels, and applied a gaussian blur. That way, the user removed all the details of the image of the Moon downloaded from the web.
This technical yet tricky procedure further added the upscaling of the image by 4 times so the phone can consider it as a long-distance natural Moon. The user later full-screened the image on the monitor, turned the room dark, and captured the screen through a Samsung phone from a distance.
The Samsung phone identified the displayed moon as the real Moon and the Artificial Intelligence refined the shot and delivered a clear and vibrant image of the Moon. For the user, it might be the first time to see the AI technique as generally we don’t try to test the camera and space zoom.
There’s nothing like cheating nor Samsung phones are producing fake Moon images. The company already revealed that an intelligent camera technique and different kinds of machine learning work behind the shot so user can get the most adorable variant in Space Zoom.
AI is being used everywhere. What do you think, is Samsung really cheating with Space Zoom? Let us know through Twitter.

Today, we discuss how your Samsung phone’s Space Zoom photography feature works. Regardless, hardware is the key factor to introduce a huge zooming/magnification range, but, well-optimized software significantly improves the overall experience. That’s what Samsung does, others not.
Way back in 2019, Samsung introduced AI technology to the mobile camera when it launched the Galaxy S10 series. The company developed a Scene Optimizer feature that helps AI to recognize the subject and provide you with the best photography experiences regardless of time and place.
Specifically for Moon photography, Samsung Galaxy S21 series debuted even better optimization with artificial intelligence. Galaxy flagships starting the Galaxy S21 series recognize Moon as the target using learned data, multi-frame synthesis, and deep learning-based AI technology at the time of the shooting.
In addition, a detail improvement engine feature has also been applied, which makes the picture clearer. If you don’t want to capture photos using AI technology, you can do it by just disabling the Scene Optimizer from the camera viewfinder.
Data learning process for Moon recognition engine
Samsung developers created the Moon recognition engine by learning various shapes of the Moon from full to crescent, based on images that people actually see with their eyes on Earth. It uses an AI deep learning model to show the presence and absence of the moon in the image and the area (square box) as a result.
Moreover, the pre-trained AI models can detect lunar areas even if other lunar images that have not been used for training are inserted. However, the Moon can’t be normally recognized if it is covered by a cloud or something else (non-lunar planets).
Brightness control process
Well, AI enhances photography of the Moon, but better results require powerful hardware part as well. As it’s difficult to detect a small Moon in regular AI photography, the Moon’s photography is possible from 25x zoom or higher.
As soon as your Galaxy phone’s camera recognizes the Moon in the high-magnification zoom, the brightness of the screen is controlled to be dark so that the Moon can be seen clearly on the camera viewfinder, alongside maintaining optimal brightness.
If you shoot the Moon in the early evening, the sky around that is not the color of the sky you see with your eyes, but it is shot as a black sky. The tech behind this function is that when the Moon is recognized, it changes the focus to infinity to keep the moon in focus.
Shake control
Starting the Galaxy S20 series, Samsung shipped the Ultra variants (S20 Ultra/S21 Ultra/S22 Ultra) with the capability of magnification up to 100x. When the user shoots the Moon with 100x zoom/magnification, it looks greatly magnified, but it is not easy to shoot because the screen shakes due to shake of hands.
For this, Samsung created a functionality called Zoom Lock that reduces shaking when the Moon is identified so it can be stably captured on your Galaxy phone’s screen without a tripod. Zoom Lock unites OIS and VDIS technology in order to maximize image stabilization to radically surpass shaking.
If you touch the screen at high magnification or shine the Moon without moving for more than 1.5 seconds to lock, the zoom map border (in the upper right of the screen) changes from white to yellow, and the Moon no longer shakes, making it easy to shoot.
Tips to take Moon shots in 100x zoom:
- After rotating the Galaxy in landscape mode, hold the phone with both hands.
- Check the position of the Moon through the zoom map and adjust it to the center of the screen.
- When the zoom map border changes to yellow, press the capture button to picture the Moon.
Learning process of lunar detail improvement engine
Once the Moon is visible at the proper brightness, your Galaxy Camera completes a bright and clear moon picture through several steps when you press the capture button. At first, the application double-checks whether the Moon detail improvement engine is required or not.
Second, the camera captures multiple photos and synthesizes them into a single shot that is bright and noise-reduced via Multi-frame Processing. Due to the long distance and lack of light in the environment, it was not enough to give the best image even after compositing multiple shots.
To overcome this, the Galaxy Camera uses a deep learning-based AI detail enhancement engine (Detail Enhancement technology) at the final stage to effectively remove noise and maximize the details of the Moon to complete a bright and clear picture.
Moon filming process
Samsung’s stock Camera application utilizes various AI technologies, which are detailed above, to provide clear Moon photos through various processes. Once focussed, AI automatically realizes the scene being shot and uses scene optimization technology to adjust settings for Moon quality.
To make Moon photography stable and easier, the Zoom Lock function, an image stabilization function, is used to provide clear moon photos on the preview screen. Once the Moon is positioned within the screen in the desired composition, press the shooting button to start shooting.
At this time, the Galaxy Camera combines multiple photos into a single photo to remove noise. As result, a bright and clear moon picture is completed by applying detail improvement technology that brings out the details of the moon pattern.
Update – March 12.
Samsung itself revealed that multiple processing techniques work before the Galaxy phone produces a crispy image of the Moon. Meanwhile, there’s a thread posted on Reddit that makes the shooting technology controversial, which shouldn’t be there.
Lin Jun-cheng, who previously worked at Taiwan-based TSMC has joined Samsung Electronics, reports say. The company appointed Lin as Senior Vice President of the advanced packaging team under Samsung’s chip business division, Device Solutions.
In addition, the KoreaHerald report believes that Lin Jun-cheng’s key responsibility is likely to be overseeing the development of cutting-edge packaging technology, which plays a key role in enhancing advanced higher-performance chipsets.

From 1999 to 2017, Lin worked at TSMC and then served as CEO of Taiwanese semiconductor equipment maker Skytech. It shows how Samsung beefs up efforts to strengthen its prowess in chip packaging under the leadership of Samsung’s co-CEO Kyung Kye-hyun.
Galaxy-exclusive chipset
In the recent past, the South Korean tech giant established a dedicated team as part of research and development on its dream chipset. To speed up the development and accuracy of the project, the company is continuously putting in efforts and hiring expertise from various tech titans.
A task force is also said to have been launched last year to speed up the commercialization of advanced packaging technology. Last year, Samsung also hired Kim Woo-pyeong, a former engineer at Apple – another archrival – as head of the company’s packaging solution center in the US.
