Beyond its ergonomic ambitions, the R3 is a showcase for Sharp’s legendary display engineering. As the company behind the first commercial LCD calculator and many of Apple’s Retina displays, Sharp knows pixels. The R3’s IGZO (Indium Gallium Zinc Oxide) panel is a technological marvel. It offers incredibly low power consumption and allows for a 120Hz refresh rate long before it became a flagship standard. The contrast and color accuracy, particularly for a non-OLED panel, are stunning. In a market saturated with oversaturated AMOLED screens, the R3’s LCD provides a natural, clinical precision that photographers and video editors might appreciate. The 3120 x 1440 resolution results in a pixel density so high (over 500 ppi) that the screen looks less like a digital interface and more like a printed photograph held under a magnifying glass.
The defining feature of the Aquos R3 is its screen—or rather, its two-in-one screen. At first glance, the 6.2-inch IGZO display appears to have a glaring flaw: a sizable "dual notch" or "forehead" at the top, and a large chin at the bottom. But this is a purposeful, almost defiant design choice. Unlike the iPhone’s notch, which houses facial recognition hardware, or the Essential Phone’s notch, which was a necessary evil, Sharp’s notch is a stylistic anchor. More importantly, the R3’s display boasts a dual refresh rate: 120Hz for the top portion (making scrolling silky smooth) and a standard 60Hz for the bottom. The real genius, however, is the “touch” functionality on the bottom bezel itself. Sharp integrated a capacitive sensor into the chin, allowing users to use it as a virtual home button, a gaming trigger, or a secondary scrolling surface. In practical use, this means you can hold the phone with one hand, using your thumb to scroll through a website on the main screen while your index finger rests on the bottom chin to flick through photos. It is a bizarre, deeply ergonomic innovation that solves a problem most users didn’t know they had: the tyranny of the thumb reach. sharp aquos r3
However, the Aquos R3 is a textbook example of a "cursed" device—a phone of profound strengths and equally profound weaknesses. To accommodate the unique screen and the massive 3,200 mAh battery (small even for 2019), Sharp made compromises. The phone is thick, with a glossy plastic back that feels less premium than its price tag suggests. The software experience, while nearly stock Android, is burdened by Sharp’s lackluster update schedule and a camera app that, despite using a capable 12.2MP primary sensor and 20MP telephoto lens, produces inconsistent results. The camera’s processing is slow, low-light performance is noisy, and the AI scene detection is often baffling. In a world where Google and Apple had perfected computational photography, the R3’s camera felt like a point-and-shoot from 2015. Beyond its ergonomic ambitions, the R3 is a
Furthermore, the very feature that defines the R3—the dual-notch and interactive chin—alienated mainstream consumers. For the average user, the phone looked ugly and broken. Carriers and reviewers, accustomed to the notch-less, hole-punch future, panned the design as retrograde. The R3 was largely confined to the Japanese domestic market via SoftBank, with limited international availability. It became a niche curiosity for "otaku" (enthusiasts) who valued screen quality and unique interaction over social conformity. It offers incredibly low power consumption and allows
