As promised by Google at the I/O developers conference, the search giant has begun rolling out Android's latest 4.1 (Jelly Bean) Over-The-Air (OTA) update starting with Galaxy Nexus HSPA+ devices.
Owners of Galaxy Nexus devices will receive a notification for update over the next few days. The devices already using Jelly Bean, provided on the developer units at the I/O conference, will still receive the update since it is newer than the developer version, reports GSMArena. To manually check the Jelly Bean update in your Galaxy Nexus, go to Settings>About>System Update.
After updating, users will be able to enjoy all the new features of the Jelly Bean. The next devices to get the Android 4.1 update are CDMA Galaxy Nexus, Nexus S and Motorola Xoom later this month.
The successor to Android 4.0 (Ice Cream Sandwich) brings several improvements, including a revamped , smoother User Interface (UI) thanks to Project Butter, a better notifications system and home screen management, as well as an improved voice search, text input with offline voice typing, an improved camera app and enhanced Android Beam capability. Google claims that Jelly Bean makes everything feel fast, fluid and smooth.
The Galaxy Nexus, the first smartphone to run on the Android 4.0 operating system, was announced in October last year. The smartphone is equipped with the latest technology including Google Wallet and Near Field Communication (NFC). The Galaxy Nexus features a 4.65in Super AMOLED display, a five megapixel rear-facing camera and a 1.3 megapixel front camera. It is powered by a dual-core Texas Instrument (TI) OMAP 4 Cortex-A9 chip clocked at 1.2GHz.
