What is a 5G smartphone? “AQUOS R5G” in photos

On February 17, Sharp unveiled a smartphone for the 5th generation mobile communication system "5G" for the first time in Japan. 5G is scheduled for commercial service in the spring of 2020, with preparations being made by each carrier. The 5G smartphone announced this timeAQUOS R5GIs also expected to be handled by carriers. Check out the photos of the presentation to see what the design is and what features it has.

  • Sharp's "AQUOS R5G". Scheduled for release in spring 2020


AQUOS R5G is an Android smartphone that supports 5G communication. The screen is a Pro IGZO liquid crystal display that was also used in AQUOS R3, and the size is about 6.5 inches [3,168 × 1,440 dots]. The 8K wide camera [quad lens] with presence is mounted on the back. The main body is about 162 x about 75 x about 8.9mm, weighs about 189g, and is available in three colors: earth blue / black ray / aurora white.

  • The back is made of a material that reflects like a mirror. It is earth blue / black ray / aurora white in order from the left

  • A slightly large body to operate with one hand. However, despite being slightly larger than the current flagship AQUOS R3 [about 156 × about 74 × about 8.9 mm], the weight was plus 4 g, and the lightness in my hand was impressive

  • The back of the black ray. The camera part is protruding for less than 1 mm

  • Aurora white back. The small hole at the bottom right of the camera is a microphone hole for movie shooting

  • Earth blue back. The impression changes considerably depending on the degree of light, but it was deep blue with depth

By the way, as a basic performance, CPU is Qualcomm's SoC "Snapdrgon 865 5G mobile platform", memory is 12GB, storage is 256GB [the latest UFS3.0 + WriteBooster standard] built-in. 5G communication covers only the frequency band below 6GHz [Sub6]. The communication speed is 4 Gbps at the fastest, claiming that 2 GB movies can be downloaded in 4 seconds.

Camera and interface

The camera is compatible with AQUOS smartphones and the first Japanese manufacturer's terminal to support 8K video recording [recorded in H.265 format]. The rear lens consists of an ultra-wide-angle, standard, and ToF [depth] sensor that covers twice the telephoto and 120-degree angle of view in order from the top. There is also "8K focus playback" that tracks the subject of the video with AI, and 4K HDR shooting function.

There is no stranger to the interface, the charging port is USB Type-C. An earphone jack is also provided on the top.

  • Out camera. A telephoto equivalent to 52mm [2x optical], a super wide-angle equivalent to 19mm covering an angle of view of 120 degrees, a standard equivalent to 26mm, a ToF [depth] sensor. Also equipped with NFC, compatible with Osaifu-Keitai

  • A water drop type 16.4MP front camera is on the front. Can also be used for face authentication [fingerprint authentication sensor is also installed under the display]

  • The charging port has a USB Type-C port at the bottom

  • SIM slot is installed on the left side. The thickness of the main body is 8.9 mm, it does not feel so thick

  • Earphone jack is on the top


AQUOS R5G has some features besides 5G communication support and 8K camera. What impressed me when I saw the actual machine at the presentation venue was the lightness when picked up, the heat measures unique to 5G, and the display function of the Pro IGZO liquid crystal display.

In particular, the display incorporates many new functions, such as the series's first maximum brightness of 1,000 cd / square meter, the first image quality adjustment function with illuminance sensor “ Smart Color Matching '', “ HDR enhancer '' which automatically adjusts the brightness balance of HDR video Was The refresh rate is 120Hz, which is the same as AQUOS R3.

  • AQUOS R5G [left] and the current flagship AQUOS R3 [right]. The screen size increased from about 6.2 inches to about 6.5 inches, but weighed only 4g. When actually picked up, it is light enough to think that it may be a mock [a model without contents] for a moment

  • Since the amount of heat generated by mounting a 5G-compatible SoC increased, it was said that a new system that adopted a copper block / copper shield and disperses heat quickly was developed.

  • Internal structure of AQUOS R5G

  • HDR enhancer is a technology that analyzes displayed content in real time to control the tone curve and backlight brightness, and draws images more beautifully while maintaining power savings. When this is turned on, the brightness of the backlight is reduced in dark images, so that black is more likely to appear darker, and there are advantages of reduced gradation loss and lower power consumption. The adjustment that the backlight was squeezed and the power consumption was low while the actual appearance was almost the same between on / off seemed to work quite well from the viewpoint of the venue

  • Wireless communication conforms to Wi-Fi 6 [11ax]. Compared to AQUOS R3 compliant with Wi-Fi 5 [11ac], the demonstration environment at the venue was about 250 Mbps faster

  • A game mode that optimizes the display of game content will continue to be installed. Draw details more accurately while displaying in-game objects in more natural shades

  • Equipped with illuminance sensor + RGB sensor for the first time. It has a "smart color matching" function that adjusts the image quality according to the environment. Although it is somewhat difficult to understand in the photo, under orange light, the pattern on the girl's clothes of the subject was displayed more clearly on the right model with this function turned on

  • Scheduled to be released in the spring of 2020 when 5G commercial service starts
