No folks, Google+ will still be there however the screen that you view it on will not have a +. Confused? Well, the Samsung Galaxy SII has a Super Amoled Plus screen whereas the Galaxy Nexus has just (just?) a Super Amoled.
So what does this actually mean then to the ordinary Joe phone user? Well, Rather than using the full RGB display found in the Super AMOLED Plus devices (where each pixel has its own red, blue, and green pixels), the Galaxy Nexus will use the same RGB PenTile display that has been found in all Nexus devices to date which forces pixels to share each others sub pixels.
Still confused? OK, to sum it up the screen wont have as many colours showing and the pixel density will be lower however if you have seen and liked the screen on the SII then there should be no reason for you notice and not like the Galaxy Nexus.
