Huawei may have spilt the beans on Google's upcoming Android mobile operating system, all but confirming that the manufacturer's Ascend D quad will support Jelly Bean.

While speaking to reporters - including the International Business Times UK - at Mobile World Congress (MWC) in Barcelona, a spokesman from Huawei said that the company has a very good relationship with Google, and that all devices shown at MWC will be upgradable.

Talking about the Ascend D quad smartphone - which currently runs Android 4.0 Ice Cream Sandwich, the spokesman said: "We have a very, very good cooperation with Google, all of our handsets are upgradable, so why not this one?"

This suggests that all of Huawei's new devices - including the Adcend D quad smartphone and the MediaPad 10 tablet - will be getting the Jelly Bean upgrade from Google when it becomes available.

On Sunday, Huawei announced the all-new Ascend D quad phone, which it claims to be the most powerful quad-core smartphone in the world - and the 10-inch MediaPad tablet, which will go up against Apple's iPad 3 when it goes on sale later in the year.

Little else is known about Android 5.0 Jelly Bean, other than it almost certainly exists, given that Google has a giant green Android robot and a bowl of jelly beans on its stand at MWC.
