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.
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.
History and availability
The Nexus S was demonstrated by Google CEO Eric Schmidt on November 15, 2010, at the Web 2.0 Summit. Google officially announced the phone on their blog on December 6, 2010. The phone became available for purchase on December 16 in the United States and on December 22 in the United Kingdom.
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. The alternate SC-LCD (Super Clear LCD) version of the phone is the GT-I9023 which is meant for the European (non-UK) market.
In May 2011 Sprint introduced its Nexus S in the US. Unlike the GSM version, the Sprint Nexus runs on its WiMax network and uses CDMA instead of GSM.
Also in March 2011 Vodafone released a white version of the phone on its web store in the UK.
In the United Kingdom, the Nexus S is sold at Carphone Warehouse and is available on the Vodafone, O2, T-Mobile, 3 and Orange networks.
In France, it is available through SFR and Bouygues Telecom.
In India, Samsung officially announced sale of the unlocked version with Super AMOLED screen i9023, which will support all GSM-based carriers throughout the country.
In Canada, the Nexus S became available at most carriers in April 2011 in two versions, one for Telus, Bell, and Rogers with 3G frequencies of 850/1900/2100 MHz, and the other for Wind/Mobilicity/Vidéotron, using 3G frequencies 900/1700/2100.
In Australia, the Nexus S became available in both black and white. It is available on Vodafone and its virtual provider Crazy John's.
Hardware
Processor
The Nexus S has the Samsung Exynos 3110 processor. This processor combines a 45 nm 1 GHz ARM Cortex A8 based CPU core with a PowerVR SGX 540 GPU. The CPU core, code-named "Hummingbird", was co-developed by Samsung and Intrinsity. The GPU, designed by Imagination Technologies, supports OpenGL ES 1.1/2.0 and is capable of up to 20 million triangles per second.
Memory
- The Nexus S has 512 MB of RAM (Mobile DDR) (128MB is assigned to the GPU, leaving 384MB free for the OS),
- 16 GB of NAND memory, partitioned as 1 GB internal storage and 15 GB "USB storage".
- The phone does not support additional storage capacity such as microSD.
Screen
The Nexus S is the first device to use a 4.0-inch (100 mm) slightly curved glass touchscreen, described by Google as a "Contour Display", with a Super AMOLED 800 x 480 WVGA PenTile matrix display manufactured by Samsung. In markets outside Canada, US, and UK, a Super LCD is supplied instead.
Software
The phone shipped with Android 2.3 (Gingerbread) and was the first device to ship with the updated OS. On December 19, 2011, Google released Android 4.0 (Ice Cream Sandwich) for the Nexus S. The automatic update was suspended, allegedly due to poor battery performance. The UMTS/GSM variants was among the first to receive Android 4.0.4 in March 2012. 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.
On June 27, 2012, at the Google I/O conference, it was announced that the Nexus S would be one of the first devices to receive an upgrade to Android 4.1 (Jelly Bean), along with the Motorola Xoom and Galaxy Nexus, began on July 26, 2012.
In October 2012, the Jelly Bean 4.1.2 OTA update was released, and is the last official OS released for these devices.
On November 13, 2012, it was announced that the Nexus S would not be updated to Android 4.2 (Jelly Bean). It is still supported by independent developers, though, and Android 4.2.2-based as well as 4.3-, 4.4-, 5.1- and 6.0-based alternative software can be installed.

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 – 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.
