Samsung is preparing notable upgrades for its upcoming Galaxy S26 Ultra smartphone, focusing on enhanced camera capabilities, improved charging technology, and a slimmer design. The device is expected to retain its 200-megapixel main sensor but will feature a wider aperture to improve imaging performance. Additionally, the Galaxy S26 Ultra will have a thinner body, approximately 7 millimeters thick, a slightly larger and taller frame, and a lighter build compared to its predecessor. The display is anticipated to be a 6.9-inch panel incorporating CoE depolarizer technology and third-generation anti-reflective glass. Alongside hardware advancements, Samsung is also revising its software strategy with the forthcoming One UI 8 update based on Android 16. This update will globally block bootloader unlocking, effectively restricting the installation of custom ROMs and limiting user modifications. This change marks a shift from previous policies where bootloader unlocking was only restricted in certain regions. Meanwhile, Android 15 is expected to introduce a feature allowing Galaxy devices to be unlocked using a smartwatch. These developments indicate Samsung's dual focus on enhancing device performance while tightening software security and control.
