Tech History: The First Curved Smartphone Was Entirely Rounded, Not Just the Display

Curved display smartphones are now considered premium, with sleek edges that make them visually striking and often more expensive. But did you know that the first curved smartphone looked very different from today’s models? Instead of just curved edges, the entire phone itself was rounded. Let’s take a look at the fascinating history of curved display smartphones, from their inception 12 years ago to their current evolution.

The Beginning of Curved Display Smartphones
Today, even budget smartphones feature curved screens as a standard design element. However, 12 years ago, in 2013, curved screens were limited to high-end models. The aim of these early curved smartphones was not just aesthetic—it was about offering better viewing angles, improved grip, and enhanced software experiences. Thanks to OLED technology, curved displays became a reality and soon became a hallmark of premium smartphones.

Samsung Galaxy Round: The First Curved Smartphone
Samsung led the charge by launching the Galaxy Round in South Korea in 2013. The phone featured a 5.7-inch Full HD Super AMOLED display, but unlike today’s curved edges, the device was U-shaped at the back for a comfortable grip in the palm. While this design didn’t immediately become popular, it demonstrated that smartphone screens could be designed in unconventional ways.

LG G Flex: Taking Curves to the Next Level
Later in 2013, LG introduced the LG G Flex, which featured a more aggressively curved design with a 6-inch POLED display. The vertical curve brought the microphone and speakers closer to the mouth during calls, and the device included a self-healing back panel that repaired minor scratches automatically. With its design and innovative features, the LG G Flex was one of the most advanced smartphones of its time.

Samsung Galaxy Note Edge: The Modern Curved Screen Era Begins
In 2014, Samsung launched the Galaxy Note Edge, introducing a more practical and modern curved screen. Unlike its predecessors, only one side of the screen was curved, while the other remained flat. This marked the start of Samsung’s EDGE series, demonstrating that curved displays could be both stylish and functional.

Samsung Galaxy S6 Edge: Curved Screens Become Premium Signifiers
By 2015, the Samsung Galaxy S6 Edge popularized dual-curved screens, giving smartphones a distinctive and luxurious appearance. Curved displays transitioned from experimental designs to integral features of flagship phones. Following this trend, other brands like Huawei and Vivo adopted curved screens in their premium models.

Why Curved Displays Became Synonymous with Premium Smartphones
Over time, many brands incorporated curved screens into their high-end devices, creating a trend that associated curved displays with luxury and innovation. Initially, the technology was expensive, and the premium look encouraged buyers to spend more.

However, after 12 years, manufacturers are exploring new designs. Flat displays are making a comeback in premium smartphones, while curved screens are increasingly seen in mid-range and budget models. Rumors suggest that Apple might launch its first curved iPhone on its 20th anniversary, possibly featuring dual or even quad-curved displays, potentially reigniting the era of premium curved screens.
