As its newer Nexus brethren receive Android 4.2, many can’t help but wonder why the Samsung-built Nexus S was left out. Despite now being a somewhat dated device with “only” 512 MB of RAM and single core processor, the device has managed to keep up with it’s younger siblings fairly well. Admittedly the performance of the latest Android builds has been lacking in some areas, but that only seems to spur the developers here at XDA on to try and push the phone to its absolute limits.
XDA Senior Member knzo has recently released a version of 4.2 for the Nexus S, which just goes to show that it’s not ready to lay down and die quite yet. It’s a little difficult to be certain about what is or isn’t functional at the moment, as the development thread isn’t fully updated yet. However, the general feedback seems to be quite positive. There are of course some bugs, as you would expect. Some users have reported minor issues with the camera and the new gesture typing feature not working. This, of course, can be resolved by installing the 4.2 keyboard separately. Some people are also reporting issues when flashing GAPPS, but as the Play Store is included by default, these are easily enough installed one-by-one.
If you’d like to get 4.2 up and running on your Nexus S, make sure to read through the original thread for all the details.___________________
