The Samsung Galaxy S4 Nexus edition could cost as little as £479 if it arrives in the UK. This is based on the current pricing structure of the Nexus 4 when looking at UK/US price differences and then applying it to the US price of the S4 Nexus which is $649.
Taking into account Google will no doubt want to undercut Samsung's current UK price which is as high as £579 at Phones4U one could assume they'd offer this as a way of beating the competition.
Unveiled at Google I/O the Nexus edition is essentially a 16GB Samsung Galaxy S4 but with a few subtle changes including an unlocked Bootloader and a completely untouched version of Android 4.2 with Google promising full software support.
The hardware is the same as that found on the US version of the 16GB Samsung Galaxy S4 which means you'll get a quad-core 1.9GHz processor along with the 5-inch Full-HD display.
There's the same 2GB of RAM found in the Google Nexus 4 along with the same GPU so it's likely you'll be choosing the Google-flavoured S4 for its screen and grunt.
On top of that the S4 has a distinct advantage in the memory and battery department with a larger replaceable 2,600mAh battery and the ability to expand the memory by up to 64GB.
Of course the big advantage is the fac that it comes with a completely un-skinned version of Android 4.2 which means no TouchWiz and of course none of the extra software features such as 'Air View'.
Google has only unveiled one version so far in the form of a white 16GB variant and it's not even clear if the handset will be arriving in the UK, but for those who want an uncluttered Android experience it'll be fingers crossed when the handset is due to land at the end of June.
