Google announced Tuesday that its Jelly Bean rollout has begun, and Galaxy Nexus HSPA+ devices are the first to upgrade. Owners of that device, which runs on AT&T and T-Mobile, can expect to receive update alerts over the next several days, according to a Google+ post announcing the Android 4.1 push.
Galaxy Nexus, Nexus S, Motorola Xoom and Nexus 7 owners will be up next, Google says.
Google took the wraps off Jelly Bean last month at I/O, its annual developers conference.
One feature the company is touting in its new operating system is Project Butter, meant to make the overall Android experience smoother and quicker. Early Mashable tests found that Project Butter, which includes an enhanced predictive keyboard, isn't just hype -- it actually makes a noticable difference.
Resizable widgets, enhanced NFC capability and Siri-like voice search are among Jelly Bean's other Android enhancements. Perhaps Jelly Bean's most innovative feature, however, is Google Now. The opt-in service tracks your behavior on your phone to send you unsolicited updates and information later on.
