Google has recently rolled out Android 4.2 updates for Galaxy Nexus and Nexus 7 but surprisingly left out Nexus S. Despite having a 1GHz single core processor and a half GB of RAM, the device has still managed to do fairly well. The Samsung Nexus S may have been abandoned by Google but developers don’t seem to agree with the search giants and has finally pushed out the Android 4.2 for Samsung Nexus S.
Thanks to XDA Senior Member knzo who actually released the latest Android 4.2 version for Nexus S devices and proved that the Nexus S has got still some juice in it. However, it’s still hard to say what features are working and what not as it is still under development so you can expect several bugs that will surely get fixed with time. Though in general, the response was quite positive and no developer has yet reported any major issue. Some users have reported some minor issue with the camera and the new gesture typing keyboard that came as a default in Android 4.2 but this particular keyboard problem can be fixed easily by installing the Android 4.2 Jelly Bean keyboard from the Google Play Store. Some other users have also reported some issues while flashing Google apps, but as long as the Play Store app is installed in the ROM by default, these can be installed through the app store easily and anytime. So if you aren’t patient enough to test out 4.2 on your Nexus S device then check out this thread to get detailed information and download links.
