Samsung Galaxy S20


Samsung Galaxy S20 is a line of Android-based smartphones designed, developed, marketed, and manufactured by Samsung Electronics as part of its Galaxy S series. They collectively serve as the successor to the Galaxy S10 and were unveiled at Samsung's Galaxy Unpacked event on 11 February 2020.
The S20 line consists of flagship Galaxy S20 and Galaxy S20+ models differentiated primarily by screen size, as well as a larger camera-focused model, the Galaxy S20 Ultra. Key upgrades over the previous model, in addition to improved specifications, include a display with a 120 Hz refresh rate, an improved camera system supporting 8K video recording and a super-resolution zoom of 30–100×, depending on the model.
The phone was released in the United States on 6 March and in Europe on 13 March. The Galaxy S20, S20+ and S20 Ultra launch prices started at $999, $1199 and $1399.
It is the first smartphone lineup to receive USB fast-charger certification from the USB Implementers Forum.

History

The title of the phone was originally presumed to be the Galaxy S11, due to it being the logical extension from the predecessor. However, successive leaks in January 2020 revealed the title of the phone to be the Galaxy S20, because of the multiples of 10, rather than 1. In addition, details regarding the phone were leaked widely before the release, to the extent that almost all details regarding the specifications and design of the phone were known before the release. Leaker Max Weinbach obtained the actual phone a month before the release, confirming everything the community already guessed. Commentators remarked that by February, "most everything the company is planning to introduce has already leaked out." In addition to charts on the phone's specifications, marketing material and images of the phones themselves in real-life were leaked.

Design

The Galaxy S20 series maintains a similar design with the Samsung Galaxy Note 10, with an Infinity-O display containing a circular punch-hole in the top center for the frontal selfie camera. In a departure from past Galaxy S designs, the rear camera array is not centered, but located in the corner with a rectangular protrusion similar to that of the iPhone 11 and the Google Pixel 4. The S20 and S20+ house three or four cameras respectively in the bump, while the S20 Ultra houses four cameras in a larger bump. There are seven color options: Cloud Pink, Cloud White, Cloud Blue, Aura Blue, Aura Red, Cosmic Grey and Cosmic Black. Cosmic Grey is available in all size variants, while Cosmic Black is limited to the S20+ and S20 Ultra, Cloud Blue is limited to the S20 and S20+, and Cloud Pink is exclusive to the S20. For the S20+, Aura Blue, previously used on the Note 10+, is exclusively sold at Best Buy in the United States and through T-Mobile and Tele2 in the Netherlands, while Aura Red is exclusive to Korea Telecom. Cloud White availability varies by country; in the United States it is exclusive to Verizon for the S20 with Ultrawide Band support. The S20 is sold in Italy, the S20+ is sold in Italy and Spain, and the S20 Ultra is sold in China and Germany.
In June 2020, Verizon released the Galaxy S20 5G UW. Differences from the S20 include the addition of mmWave, only 8GB of RAM, and no MicroSD slot. Moreover, Samsung released the Galaxy S20+ 5G BTS Edition in summer 2020, with the color "Haze Purple."

Specifications

Hardware

Chipsets

The S20 line comprises three models with various hardware specifications; international models of the S20 utilize the Exynos 990 system-on-chip, while the U.S., Canadian, South American, Korean, Chinese and Japanese models utilize the Qualcomm Snapdragon 865.It has the capacity to handle autocad because of the massive 12gigs of rams and processor

Display

A 1440p "Dynamic AMOLED" is featured with HDR10+ support and "dynamic tone mapping" technology. The S20 and S20+ have a 6.2-inch display and a 6.7-inch display, respectively, while the S20 Ultra has a 6.9-inch display. The displays have curved sides that slope over the horizontal edges of the device, and a wider 20:9 aspect ratio is used in addition to a 120 Hz refresh rate double that of the S10.

Storage

The base amount of RAM is 8 GB, with an additional 12 GB option for the S20 & S20+ and a 16 GB option for the S20 Ultra. 128 GB of internal storage is standard and the S20+ & S20 Ultra also offers 256 GB and 512 GB options, with up to 1 TB of expansion via the microSD card slot. Verizon's Galaxy S20 5G UW model is not equipped with a MicroSD slot. Biometric options remain the same, with the S10's ultrasonic in-screen fingerprint reader carried over.

Batteries

The S20, S20+ & S20 Ultra contain non-user-replaceable 4000 mAh, 4500 mAh, and 5000 mAh Li-Po batteries respectively, and Qi inductive charging is supported at up to 15W as well as the ability to charge other Qi-compatible devices from the S20's own battery power, which is branded as “Samsung PowerShare”. Wired charging is supported over USB-C at up to 25W for the S20 & S20+ and 45W for the S20 Ultra.

Connectivity

Connectivity options have been improved with the implementation of 5G technology for all models. However, only Verizon models are compatible with ultra-fast millimeter-wave networks, and the audio jack has been omitted entirely.

Cameras

The cameras on the Galaxy S20 series improved considerably over its predecessors, although unlike the S9 and S10, the aperture on the main lens is fixed. While the megapixels of the main and ultra wide sensors remained unchanged on the S20 and S20+, the telephoto sensor received some improvements. The 64-megapixel telephoto camera, branded as “Space Zoom”, supports 3X hybrid optical zoom and 30X digital zoom at 64 megapixels on the new telephoto sensor instead of 12 megapixels at two times on the S10 and 30 times digitally.
The S20+ receives a time-of-flight sensor in addition to the regular S20's cameras. The Galaxy S20 Ultra has a quadruple lens setup that supports 4X optical zoom and 100X digital zoom, with a 108-megapixel wide image sensor, a 12-megapixel ultra-wide sensor and a 48-megapixel periscope telephoto sensor accompanied by a time-of-flight sensor. Both the wide-angle and telephoto sensors use pixel binning to output higher quality images at a standard resolution, with the wide-angle sensor using Nonacell technology which groups 3x3 pixels to capture more light.
The front camera is able to record video footage at 2160p.
A new camera mode was introduced called Single Take, which allows users to capture photos or videos at the same time with different sensors automatically. All three models can also record 8K videos at 24fps with a bit rate of 80 Mbps, which will consume about 600MB of storage per minute. On the S20 and S20+, this is enabled by the 64 MP telephoto sensor, whereas the S20 Ultra's 108 MP wide sensor natively supports 8K video.

Software

All three phones run on Android 10 and Samsung's custom skin One UI 2.1.

Known issues

Even before the general release, reviewers have seen autofocus and skin smoothing issues with the cameras, especially with the Galaxy S20 Ultra. Samsung is working on a fix, but the Exynos model continues to have autofocus issues after an update that was supposed to fix them.
Users are reporting that the Snapdragon version has GPS lock issues, the Exynos model has heating issues, the latest update to the Exynos introduced a green display tint issue, and the camera glass cracks spontaneously.
