Samsung launches Galaxy S25 smartphones

BitDepth#1496 Mark Lyndersay IF THERE was any theme underlying Samsung's launch last week of its new S25 line of premium smartphones, it was artificial intelligence. Specifically the Gemini AI model developed by Google which takes pride of place on these new Samsung devices. There was little mention of Samsung's previous effort at assistive software, Bixby, which seems set to lose its throne on the pane immediately left of every Galaxy phone's home screen since its introduction and will probably end up relegated to becoming just another app in the app drawer. New S25 series owners will get six months of free access to Gemini Advanced with their new phone. Churlish Samsung AI fans will side-eye Google Pixel owners who get a year with their new phones. Samsung has also been working with Oxford Semantic Technologies to use their Knowledge Graph tech to improve the correlation of user data on these new smartphones. All this will be rolled into what the company describes as its Personal Data Engine, which will be protected by its Knox security technology. The new data engine includes an on-device Large Language Model (LLM), which will warn users before accessing online resources if it needs a deeper database than the one on the device. Personal user data will also be written into a private blockchain, the benefits of which were not made clear during the launch event. AI will be present on the device's home screen through the Now Bar, which taps personal information such as appointments to create a Daily Life Summary, an effort at organising retained information into actionable listings. Beyond that, it seemed that the really exciting news was waiting in the wings for its turn. Was there something showing a tri-fold phone? What's the story with the new extended reality headset? Is there going to be an ultra-thin S25 Edge to resume Samsung's super-thin, large phone challenges to the industry? What's this about anti-oxidant tracking in the health app? How is that going to be tracked? Why no update on how the company's smart ring, Oura, is doing? Beyond actual communication, one of Samsung's premium smartphone's selling points has been the capabilities of its camera system. Since the introduction of the S23, the improvements have been incremental and in the S25 seem largely driven by software. Samsung has slightly increased the size of the camera sensor in its S25, switching to in-house hardware resulting in a bump in capture size for the ultra-wide lens from 12 megapixels to 50. A larger sensor also pays dividends in improved light sensitivity, reduced noise and larger file sizes, but there's no equivalent change in capture sizes for the other lenses in the phone over the S24. A 10x "camera quality" capture option is reputed to be a crop of the 5x telephoto lens, but previous "ghost" lenses that don't exist as actual glass on smartphones generally haven't delivered the quality of the captures from lenses that are actually built into the device. Perhaps the widespread use of AI will improve image results, but that remains proof awaiting the arrival of Samsung's newest pudding. Most announced improvements, including those made to the ProVisual Engine, are software-driven. So there are tweaks to the phone's retouching capabilities. The Best Face feature uses artificial intelligence to do face replacement on multiple frames of group photos. The Portrait-capture setting promises to improve the separation between subject and background, long a challenge for smartphones with plenoptic technology to do software tricks to create lens optical effects. Samsung introduced depth mapping as far back as the Note 10, following former market challenger Huawei in implementing the technology. More useful for videographers are devices that now capture LOG video, a raw capture format preferred by professional videographers, and some impressive noise gating on the built-in microphone. The S25 line benefits from incremental improvements. A more shatter-resistant Corning Glass screen, a commitment to recycle the cobalt from batteries in old phones to produce new ones and more recycled aluminium used in the frame. But Samsung, as with many other technology companies, is flirting with greenwashing here. Any recycling at all is better than none, but a commitment to take old devices in, disassemble them and recover reusable materials while managing the dispensation of non-recyclable components would hit harder. Samsung has announced availability of the new S25, S25 Plus and S25 Ultra in major markets on February 7 and in TT from February 21. Mark Lyndersay is the editor of technewstt.com.
