The Pixel and Pixel XL are a pair of Androidsmartphones designed, developed, and marketed by Google as part of the Google Pixel product line, succeeding the Nexus line of smartphones. They were officially announced on October 4, 2016 at the Made by Google event and released in the United States on October 20. On October 4, 2017, they were succeeded by the Pixel 2 and Pixel 2 XL.
The Pixels received mixed reviews, with praise for the devices' performance and cameras, but several critics noted similarities with Apple's iPhone line in terms of hardware design, and criticized the Pixels's lack of waterproofing and high price.
Google previously co-developed flagship Android devices with original equipment manufacturers through the Nexus program, which were designed to be "reference" devices for the Android platform, but the devices retained similarities to other devices made by their respective partners. Rick Osterloh, former president of Motorola, joined Google as its senior vice president of hardware in April 2016, and Google initiated development of an ecosystem of in-house products and platforms, including the Google Home smart speaker, Google Assistantintelligent personal assistant, and Google Daydream, Google's virtual reality platform. The Pixels were announced on October 4, 2016, and serve as Google's launch devices for Android 7.1 "Nougat". The song Closer by Lemaitre Music was used in the device's introductory film.
Osterloh said in an interview with The Verge that "a lot of the innovation that we want to do now ends up requiring controlling the end-to-end user experience". The Verge wrote that the Nexus program had "fulfilled its mission", with a Google spokesperson stating that there are "no plans" to make another Nexus device. The Pixel was designed by and marketed as being a Google product. Google worked with HTC on a contract basis on development but have said that the Pixels are not based on any existing HTC device. It offered Huawei the contract to manufacture the devices, but after Google refused to dual-brand the phone with credit to the manufacturer, Huawei declined the offer.
On October 4, 2017, Google announced the Pixel 2 and Pixel 2 XL smartphones, succeeding the original Pixel devices. The Pixel and Pixel XL were removed from the Google Store and discontinued on April 11, 2018.
Pixel uses an aluminium chassis, with a glass panel on the portion of the rear housing the camera and "Pixel Imprint" fingerprint sensor.
The phones have a USB-C connector supporting USB 3.0, for power and data exchange. The phone features a 3.5mm headphone jack, which received media attention for being a contrast to competing smartphone Apple iPhone 7, the first not to feature the port.
The Pixel and Pixel XL both use the Qualcomm Snapdragon 821 system-on-chip, with 4 GB of RAM. They are offered with either 32 GB or 128 GB of UFS 2.0 non-expandable internal storage.
Display and battery
The two models are differentiated by screen and battery size. The standard Pixel's display measures 5 in (130 mm) 1080pAMOLED with a 2770mAh battery, while the Pixel XL's display measures 5.5 in (140 mm) 1440p AMOLED with a 3450mAh battery.
Pixel features a 12.3-megapixel rear-facing camera, which uses an f/2.0 aperture, and a Sony Exmor IMX378 sensor with 1.55 μm pixels.
To improve capture speed, 30 frames are continuously captured per second while the camera is active. When a photo is taken, up to 10 of these frames are composed to form a single image. Later software updates to Pixel introduced "Night Sight", an enhanced low-light photography mode first introduced on one of the devices' successors, the Pixel 3.
The Pixel and Pixel XL shipped with Android 7.1 "Nougat", an update to 7.0 that was initially exclusive to the Pixel. Android 7.1 was later released for some existing Nexus devices in December 2016, but certain features remained exclusive to the Pixel.
Pixel supports Google Assistant, and provides live technical support services integrated into the OS. Similarly to Nexus devices, it receives Android updates directly from Google. Pixel also supports the Google Daydream virtual reality platform. All Pixel smartphones include unlimited full-resolution Google Photos backup for the life of the device. A November 2016 update added additional motion gestures, including double-tapping the screen to show alerts, and raising the device to wake the screen.
Google states on its support pages that the Pixel and Pixel XL are guaranteed to receive new Android version updates until October 2018, and guaranteed to receive security patches until October 2019. In August 2017, Google released Android 8.0 "Oreo" for the Pixel and Pixel XL. Android 8.1 Oreo was released for the Pixel and Pixel XL, as well as some other devices, on December 5, 2017. Although after the date Google guaranteed the Pixel and Pixel XL would receive new Android versions, Google released Android 10 to the Pixel and Pixel XL in September 2019.  Google released the final official security update to the Pixel and Pixel XL in December 2019.
The Pixel and Pixel XL received mixed reviews. Dieter Bohn of The Verge said the Pixel smartphones are "...easily the best Android phones you can buy" and gave the product a 9 out of 10, praising its long battery life and Google Assistant integration. However, criticism has been aimed at its pedestrian design and lack of waterproofing.
Matt Humrick of AnandTech praised the camera being flush with the body, but was critical of the price, stating that Nexus fans who were looking for a more affordable option would be disappointed. Chris Velazco of Engadget praised the build quality, camera, and performance, but criticized the high price, and lack of proper water-resistance present in rivals, such as the iPhone 7 and the Samsung Galaxy S7.
Writing for Ars Technica, Ron Amadeo said of the phone, "[it has] unbeatable software and support with a great camera, wrapped in a familiar exterior." Zach Epstein of BGR wrote in February 2017 that "There’s also no question that the phones feature a design that is sleek and impressive, yet all too familiar. Yes, that’s a nice way of saying that Google blatantly ripped off the iconic design that Apple has used on its iPhones for the past three generations."
In June 2017, Ars Technica reported that Google Play's app for the Pixel Launcher, an app pre-installed on all Pixel phones, had been downloaded between one million and five million times. Although the report acknowledged the measurement's imprecision, the publication credited it for providing the first possible sales numbers. In February 2018, an analysis by International Data Corporation (IDC) reported that Google shipped a combined 3.9 million Pixel/XL and Pixel 2/2XL phones in 2017, double the number of shipments from 2016, when Google shipped nearly 2 million Pixel and Pixel XL phones in three months.
The Pixel and Pixel XL have exhibited numerous problems since release, including:
Rear camera producing excessive flare (fixed in an update to Google's Camera app)
