Samsung’s tech breakthroughs that redefined smartphones
Samsung has spent decades transforming consumer electronics into something far more ambitious. Its story isn’t merely a catalog of products but a record of how the company repeatedly redefined technological possibilities, often by challenging what devices could achieve. From pioneering the first smartphone with Super AMOLED displays to introducing the first foldable phone, Samsung didn’t just follow industry trends—it set them.
The company’s roots stretch back to 1938, but Samsung Electronics officially launched in 1969. Over time, it expanded from basic electronics into smartphones, televisions, semiconductors, and artificial intelligence. Some innovations, like the S Pen or Knox security platform, became industry standards. Others, such as foldable displays and on-device AI, reshaped entire product categories.
One of its earliest milestones came in 2010 with the Galaxy S, the first smartphone to ship with Super AMOLED technology. Unlike traditional screens, Super AMOLED integrated the touch sensor and display into a single layer, creating thinner devices while enhancing contrast and color accuracy. This advancement didn’t just improve visuals—it redefined user expectations for phone screens. Samsung later evolved this into Dynamic AMOLED, now a standard in flagship devices.
In 2011, the company made another bold move with the Galaxy Note, introducing a large display paired with the S Pen. This digital stylus transformed smartphones into notebooks, allowing users to sketch, annotate, or take handwritten notes. The Note didn’t just fill a gap in the market—it created a new category. Today, the S Pen remains a hallmark of Samsung’s productivity-focused devices.
Security redefined: Knox turns phones into work hubs
As smartphones became essential workplace tools, security took center stage. In 2013, Samsung launched Knox, a platform designed to separate work and personal data on the same device. What began as an enterprise security feature expanded into a broader ecosystem, now protecting smartphones, tablets, and wearables. This shift reflected a broader transformation: phones evolved from communication tools into essential productivity devices.
The company’s innovation extended beyond hardware. In 2017, it introduced Bixby with the Galaxy S8, an AI assistant aimed at making interactions more intuitive. While competitors like Siri and Google Assistant later dominated the market, Bixby’s launch signaled Samsung’s early commitment to AI integration. The assistant has since expanded across its ecosystem, from smartphones to home appliances.
Samsung’s influence reached beyond mobile devices in 2013 with the world’s first Curved UHD TV, challenging the flat-screen norm with an immersive design. Five years later, it unveiled The Wall, a 146-inch MicroLED display that could be modularly configured. These weren’t just larger screens; they were experiments in how TVs could adapt to different spaces and uses.
The company’s impact on everyday appliances is equally significant. In 1995, Samsung introduced Twin Cooling for refrigerators, using separate systems for the fridge and freezer to maintain independent temperatures and prevent odor transfer. Nearly three decades later, this concept evolved into SmartThings and AI-powered appliances that automate household tasks. Even laundry received a technological upgrade with Eco Bubble, a system that mixes air, water, and detergent for more efficient cleaning at lower temperatures.
Foldable phones: The future of flexible design
Samsung’s most daring experiment arrived in 2019 with the Galaxy Fold, the first consumer foldable smartphone. Its 7.3-inch screen unfolded into a tablet-like form while folding into a compact design. The device didn’t just expand screen size; it questioned whether a phone’s shape needed to remain fixed. Later models, including the Galaxy Z Fold and Z Flip, turned foldables into a mainstream category.
In 2024, Samsung reinforced its AI focus with the Galaxy S24 series, embedding features like Circle to Search, Live Translate, and Chat Assist directly into the phone experience. This shift went beyond adding AI; it integrated intelligence into daily interactions, from communication to content creation. The company is now extending this approach across its entire Galaxy lineup, including wearables and smart home devices.
The Galaxy S24 series represented a major shift in how Samsung integrates artificial intelligence. Unlike earlier attempts to add AI features as afterthoughts, the company embedded these tools into the operating system itself. Circle to Search, for instance, allowed users to highlight text in images or documents and instantly retrieve related information without needing a separate app. Live Translate eliminated language barriers by translating conversations or text in real time, all within the current task. These weren’t isolated features; they became fundamental to how a phone functions, much like the S Pen or Super AMOLED had for previous generations.
AI spreads beyond phones into smart homes
While smartphones and wearables dominated recent attention, Samsung’s AI strategy was also transforming its smart home and appliance divisions. The company had established SmartThings, its connected-home platform, which included appliances equipped with artificial intelligence and other connected features.
The company’s semiconductor division, often overshadowed by its consumer products, played a key role in this experimentation. Samsung’s foundry business, one of the world’s largest, had supplied chips for Apple’s iPhones and other high-end devices. Internally, the division explored how custom silicon could enable entirely new device categories. For example, Exynos chips powering some Galaxy devices were being optimized not just for performance but for energy efficiency in always-on AI features. This meant future smartphones could run complex AI tasks, such as real-time object recognition or advanced translation, without draining battery life, a critical hurdle for widespread adoption. The work echoed Samsung’s approach to displays, where in-house research had led to breakthroughs like Super AMOLED and MicroLED.
