My poor old Nexus S has had more ROMs installed on it than leaks about an LG Nexus have appeared, but news reached us that OTA updates were pushing from the first release of Jellybean to 4.1.2 so I decided to flash back to the original, vanilla Jellybean from the Google Dev page to see how long it would take. The answer: Less than 24 hours!
In true Google styles, the update was flawless: A notification told me it was ready so I hit install now and watched.
Since I’ve already used 4.1.2 on this and other devices, I can state happily that there are some notable performance tweaks for all phones but particularly noticeable on single or dual core phones. There’s a few other tweaks that you’ll notice after a day or so which improve the user feel for the device. For those of you lucky enough to already have it, or about to receive it – Enjoy your upgrade.
**UPDATE**
We can confirm that Vodafone have approved the Nexus S update, but unfortunately Galaxy Nexus owners will need to wait a while longer!
