Multiple smartphone brands nowadays use Samsung’s ISOCELL camera. These image sensors redefine digital imaging, revolutionizing mobile photography while providing secure mobility solutions. Recently, Samsung itself explained how the ISOCELL camera evolved to make mobile photography so advanced.

We save our memories through pictures and videos on smartphones but our phones carry limited storage and naturally, a smaller device requires pixels that make the image sensor behind each picture so tiny.

At once, packing too many tiny pixels into each image sensor to ensure high quality leads to color crosstalk, which occurs when light leaks into adjacent pixels, and degrades the definition of images.

Meanwhile, Samsung is solving this problem with its ISOCELL pixel technology. Samsung ISOCELL camera enables the smartphone to produce ultra-high-quality photos even in dark environments, taking mobile photography to next level.

Advancement of ISOCELL pixel technology: Improved image quality with greater light absorption – 

Processing light is one of the most important parts when it comes to high-quality photos. Samsung’s ISOCELL pixel technology was introduced to process and absorb more light than its traditional BSI pixels. In fact, it has reduced color crosstalk between pixels by approximately 30% and increased overall efficiency where each pixel stores up to 30% more light.

Samsung continues to refine the technology, and to improve image quality even further, the new ISOCELL technology replaces the metal grid between the color filters with a more reflective material. This innovation helps reduce optical loss and increase light sensitivity.

By increasing light sensitivity, the smaller pixels in the sensor are able to absorb more light and brighter photos with even greater detail and less noise result. Whereas, to reduce optical loss in even smaller pixels, the company adopted a new merged grid array, which removed the grids between filters of similar chromaticity, thus increasing the light-absorbing area in each pixel.

The new ISOCELL solution also introduced a new material for the thin color filter to optimize the focus of the ultra-fine pixels. Recently, Samsung has advanced photosensitivity by improving the structure of the photodiode. These innovations in small-pixel technology allow ISOCELL to fully harness the power of micro-pixels.

Pixel Binning Technology: Experience crisp pictures even in dark conditions –

Due to the limitation of smaller pixel sizes, the light absorbed by such smaller pixels may be less. This presents a significant challenge when it comes to producing high-quality photos, especially in dark settings.

In the meantime, Samsung Pixel Binning technology allows smaller pixels to mimic larger pixels by combining some neighboring pixels into one. Samsung’s TetraPixel, NonPixel, and Tetra² pixel technologies merge four, nine, and sixteen pixels, respectively, to allow our smartphones to produce ultra-high quality photos, no matter the lighting conditions.

For example, when you take a photo in a dark environment, Tetra² pixel technology combines 16 pixels into one large pixel to capture more light for brighter images. Conversely, when it’s bright, the Re-mosaic algorithm rearranges the pixel array for higher image resolution, resulting in crisper, detailed images.

Of all the incredible capabilities of Samsung smartphones, one of the most notable is the ability to meet the growing demand for high-resolution photos. These lets users experience clear, detailed photos with small, yet powerful pixels through the ISOCELL mobile image sensor.

Samsung KDDI 5G Japan

Japan’s KDDI selected Samsung as the main vendor for 5G expansion. Samsung’s vRAN will be deployed by KDDI starting next year for 5G expansion. The company will provide 4G and 5G O-RAN-compliant vRAN solutions in Japan.

Samsung today confirmed selection by KDDI as a key 4G and 5G O-RAN compliant vRAN provider for their Open RAN deployment in Japan. The partnership with KDDI will help Samsung strengthen its role in Japan’s 5G expansion.

“Together with KDDI, we are thrilled to take this significant step and strengthen our presence in Japan,” said Junehee Lee, Executive Vice President, Head of Global Sales & Marketing, Networks Business at Samsung Electronics.

The South Korean tech giant noted that it’s bringing vRAN 3.0 solution, a full suite of O-RAN compliant radios supporting low- and mid-bands including advanced Massive MIMO radios and third-party radio integration support.

Kazuyuki Yoshimura, Chief Technology Officer of KDDI: “Today’s announcement represents KDDI’s dedication to bringing innovative technologies to Japan. We are proud to deliver a cutting-edge and reliable radio access network.”

Key features of Samsung CognitiV Networks Operations Suite (NOS) will also be offered. The features streamline the onboarding, deployment, and operation processes, enabling KDDI to transform its widespread network efficiently.

Beyond that Samsung and KDDI will expand the reach of Open RAN in the coming years. For now, KDDI’s Open RAN network will feature enhanced capabilities for improved energy efficiency, optimized performance, and intelligent automation.

Samsung unknown Notifications issue

Samsung Wallet getting an instant Tap to Transfer feature for Galaxy users. The latest addition unlocks instant and seamless money transfer. This move reiterates Samsung’s commitment to upscaling the Galaxy ecosystem.

The Tap to Transfer feature allows users of Samsung Wallet on Galaxy phones to instantly transfer money by tapping the backs of their devices together. The transfer process is powered by NFC technology embedded in Galaxy phones.

Samsung confirmed that the feature will be gradually supported through app updates in Samsung Wallet. The Tap to Transfer feature eliminates the need to ask for or input the recipient’s account number during transfers.

This seamless process will help Galaxy users save time and effort as well as reduce the risk of sending money to the wrong account. It’s an answer to Apple iOS 18’s Tap to Cash feature, which allows users to transfer funds with nearby ecosystem devices.

Samsung Wallet allows the recipient to set a representative account for receiving funds and can receive ‘Tap to Transfer’ payments even when their Galaxy’s screen is off – even without opening the Samsung Wallet app.

Samsung Wallet Tap to Transfer

Here’s how it works:

The user who wants to send money enters the password for their registered account in Samsung Wallet, inputs the transfer amount, then taps their phone against the recipient’s phone and completes the transfer through the default unlock method.

The recipient’s account number transmitted during the ‘Tap to Transfer’ process is encrypted and sent to the sender. Instead of displaying the full account number, only the last four digits of the recipient’s mobile phone number are shown.

The feature is currently available in South Korea and supported by Woori Bank.

Stunning Galaxy S25 upgrade eliminates S24’s display graininess

Published

on

Samsung could use the next-gen display across the Galaxy S25 series. A limited number of users reported display graininess issues on the Galaxy S24 Ultra, which is reportedly eliminated in the upcoming Galaxy S25 series.

IceUniverse reports Galaxy S25 series resolves the display graininess issue from the S24 Ultra. The tipster mentioned that the “Galaxy S25 series screen is great.” It suggests the inclusion of an upgraded screen tech in the flagships.

Pixel 9 series debuted Samsung’s best display technology. Industry expects that the Korean tech giant will now expand the cutting-edge screen to its upcoming flagships including the Galaxy S25, Galaxy S25 Plus, and Galaxy S25 Ultra.

Upgraded display is usually meant to offer vibrant colors while keeping efficiency. However, it’s a big development for Samsung consumers as the alleged graininess issue from the Galaxy S24 Ultra is finally eliminated.

Samsung is ensuring the upcoming flagships won’t lag in any way. From processor and memory to display and camera, pro-grade specifications coming to the next-gen Galaxy S line. The company could launch the S25 series in January next year.

Galaxy S24 Ultra screen graininess

Some S24 Ultra owners notice a grainy, pixelated, or textured appearance on the display. It occurs the most in certain lighting conditions or when viewing darker colors at low brightness. The anti-reflective glass was also suspected to be blamed.

However, graininess in screens could be caused by several factors such as OLED pixel arrangement,  brightness levels, and software calibration. Samsung seemingly heard consumer feedback and improved the screen hardware.
