Google Pixel launch teaser
A teaser for Google's launch event on 4 October Google

With a week remaining for the official launch of the Google Pixel, the first look of the smartphone has surfaced on Twitter. The flagship device is scheduled to debut along with another bigger version – the Pixel XL – at Google's 4 October event in San Francisco, California.

Famed tipster Evan Blass, who is notorious for providing leaked information about smartphones way ahead of their launch, tweeted a photo of the device and said: "This is the Google Pixel."

Its front design is nothing new and resembles a couple of recently released devices like the Moto G4 Plus and HTC Desire 10.

The fingerprint scanner seems to be missing from the front and is expected to be placed on the rear of the phone. It has a visibly blue theme on the home screen. The Pixel range will be the second phone after the LG V20 and the first Google handset to come pre-installed with Android 7.0 Nougat OS.

The Google Pixel, which is said to be the smaller of the two devices, was scheduled to be launched as Nexus 2016 or Nexus 7, but was re-branded. For months, the two models have been code named Sailfish and Marlin.

Both the phones are expected to have quad-core 2.0GHz 64-bit Snapdragon 821 processors with 4GB of RAM, 32GB of storage, a 12MP rear camera and an 8MP front camera. The battery capacity of the Pixel XL may be higher at 3450mAh as compared to the 2770mAh capacity expected for the Pixel model.

Among special features, some reports indicate that the phone could be waterproof to take on competitors such as Samsung and Apple. They devices are expected to be priced at around $649 (£500) and will be available in three colours – blue, aluminum and black.

The company's San Francisco event is being touted to be one of its biggest as a company executive posted a tweet saying that this time it could be as big as Android's launch eight years back. Apart from the launch of the devices, an updated version of the Chromecast is also expected to be released. Fans are also awaiting a new OS called Andromeda, which is rumoured to be a merged version of Android and Chrome OS.
