The Xperia ion is the latest Sony smartphone to get its serving of Jelly Beans as part of the new firmware, version 6.2.B.0.211.
The device will get all of the benefits this version of Android packs, including Project Butter enhancements that would make things run faster, Google Now and actionable notifications. In addition, I would assume some of Sony’s own apps would also get few tweaks here and there to further improve the experience.
If you own the Xperia ion, head over to “Settings” -> “About phone” and find your way to the update menu from there. Just make sure your battery is fully charged and that you’re connected to a fast Wi-Fi network to make this a seamless process.
