TouchWiz-less version of the phone will come with vanilla Android Jelly Bean 4.2
Google also announced a customised version of Samsung's recently released Galaxy S4. The smartphone will run the latest version of Android, not the customised version from Samsung.
"It's Google's take on Android, and it feels really awesome on the Galaxy S4," said Hugo Barra, vice president for product management at Android during the keynote for Google I/O 2013.
For the most part, the device will be the same as the 4G LTE 16GB device available today.
However, the major differences are that it will offer a skinless version of Android 4.2 Jelly Bean – the same used on Google's Nexus devices. It will also come with its boot loader already unlocked and users will receive updates as they are released.
The unlocked Samsung Galaxy S4 will be available in the US on June 26th. Neither Samsung nor Google have confirmed if the unlocked Galaxy S4 will be coming to the UK.
It will be interesting to see how much of a difference the TouchWiz-less Samsung Galaxy S4 performs compared to its regular sibling.
One area it definitely will certainly perform better in is the space available to users. In April, we reported on complaints from Samsung Galaxy S4 buyers about the system data taking up more than half of the 16GB storage on the phone.
The move is interesting due to the controversy surrounding Google and Samsung's relationship. Reports have suggested that fractures were developing due to increasing concerns over Samsung's influence over the operating system.
