The Nexus S is a smartphone co-developed by Google and Samsung and manufactured by Samsung Electronics for release in 2010. It was the first smartphone to use the Android 2.3 "Gingerbread" operating system, and the first Android device to support Near Field Communication (NFC) in both hardware and software.
This was the fourth time that Google worked with a manufacturer to produce a phone, the previous being the Google G1, myTouch and the Nexus One, all three by HTC. Following the Nexus S, the next Android Developer phone was the Galaxy Nexus, released the following year. As of September 2015, Google's current generation Nexus phones are Nexus 6P by Huawei and Nexus 5X by LG Electronics.
Nexus S is the first commercial smartphone certified by NASA to fly on the space shuttle and to be used on the International Space Station, as part of the SPHERES experiment.

The Super AMOLED version of the phone is the GT-I9020 and it is based on the Samsung Galaxy S hardware, the principal hardware differences being the absence of support for an SD card and the addition of a near field chip.

Screen

Software
The phone shipped with Android 2.3 and was the first device to ship with the updated OS. On 19 December 2011, Google released Android 4.0 (Ice Cream Sandwich) for the Nexus S.

The Nexus S 4G(aka Samsung SPH-D720), I9020A, and M200, while taking longer than the GSM variant, received the Android 4.0.4 update. Several devices, such as the Samsung Galaxy S II, have or will receive updates before these variants.

Critical reception
Joshua Topolsky, writing for Engadget review praised the devices's hardware and software, concluding "the truth is, it really is the best Android device available right now".
The review by The Register gave the Nexus S an 85% rating and summarized it as a "cool, innovative device with an eye to snatch Apple’s smartphone crown."
An AnandTech review praised the display, NFC tag reader, and Android Gingerbread operating system, but noted the lack of 720p video recording, HSPA+ baseband, and external storage support. A TechRadar review praised the Nexus S for fixing the GPS problems experienced with the Samsung Galaxy S: "The good news for those looking to upgrade from the Samsung Galaxy S â€" the GPS issues have been resolved, in that you can actually now get a signal with no problem."
CNET's review was enthusiastic about the display, operating system, and performance. CNET noted the lack of 720p video recording, HDMI output and external (SD Card) memory support. CNET also noted the "rather fragile" feel of the phone, the lack of LED notifications, and the few new features over the Nexus One.
