Google reveals new Nexus devices
Two new Android devices, the Nexus 4 handset and Nexus 10 tablet will go on sale on 13 November, Google has announced.
The handset, made by manufacturer LG, can also work as a games controller when wirelessly connected to a TV.
Google said that the screen of the new Nexus 10 tablet by Samsung has "the world's highest resolution display".
UK prices for the Nexus 4 start at £239 for the 8GB version, and £319 for the 16GB Nexus 10.
The Nexus 4 smartphone has a new panoramic camera tool called Photo Sphere which Google claims is "unlike any panorama you have ever seen".
"Snap shots up, down and in every direction to create stunning 360-degree immersive experiences," says the firm on its blog.
The battle lines are now drawn for the all-important Christmas shopping season.
Apple's iPad may have dominated tablet sales to this point, but it now faces cheaper competitors with their own media ecosystems and - in the case of Samsung's new Nexus 10 - a higher-resolution screen.
Purchase decisions may come down to brand loyalty: does a shopper identify with an Amazon, Apple, Google or Microsoft logo on the back of their device? This is still a very young market and the key players are essentially still in land grab mode.
The one thing for certain is those involved feel under pressure to innovate more quickly and lower their margins - or in some cases sell the hardware at break-even prices - all of which can only be good for the public.
In addition users will have access to "Google Now" which flags up flight alerts, hotel recommendations and package tracking based on the user's location and the contents of their previous email messages.
Nexus 10 will be able to manage multiple profiles, meaning that the tablet can be shared between more than one person.
Google says that there are more than 675,000 apps that will be available via its Google Play store. Apple claims that there are over 275,000 apps available for the latest version of iPad.
Nexus 10 has a 10in (25cm) screen with a resolution of 300ppi (pixels per inch). Its advertised battery life is 500 hours on standby or nine hours of video play.
The firm also announced that it will add music to its Google Play media store in the UK, Germany, France, Italy and Spain on the same day.
New users will be able to upload 20,000 of their existing music tracks to their online accounts for free, and then stream music via the Cloud to any Android device connected to the internet.
Google also announced a refresh of its existing tablet the Nexus 7, which will now offer 3G connectivity on a top-end model. However, all versions of the Nexus 10 are wi-fi only.
None of the new hardware will be made by Motorola.
Google purchased Motorola Mobility, the mobile phone manufacturing arm of the firm, in 2011 for $12.5bn (£7.7bn) but a spokesperson said that the company was not receiving any "special treatment".
The announcement was made after Google scrapped plans for a high-profile event to mark the launches in New York.
The event was cancelled because of the approach of Hurricane Sandy.
