Samsung is allegedly testing Google’s Android 4.3 Jelly Bean OS on its Galaxy S4, S III and Note II handsets, Sammobile reports, adding that the update software could start rolling out to its most recent smartphones as soon as next month.

Google announced Android 4.3 over the summer alongside the updated Nexus 7 at a press event, though Samsung is notorious for rolling out updates to current devices at a painfully slow speed. Samsung’s latest devices, the Galaxy Note 3 and refreshed Note 10.1 both run the latest software out of the box, and now it looks like some of the South Korean company’s other handsets may be getting an upgrade.

Sammobile claims the Galaxy S4 is first in line, and will get the update next month, followed by the S III in late Oct. or Nov. at the latest. Finally, the Galaxy Note II will get Android 4.3 in Dec., likely in an effort to push more customers to pick up the Note 3. Samsung previously promised to update its devices with Google’s latest software as quickly as possible, but until we get an official statement from the company we’d take this rumored roadmap with a grain of salt.
