The buzz is building up on Samsung's Galaxy S4 Mini, forcing the Asian tech giant to officially unveil this week the scaled-down version of its new flagship, the Galaxy S4, a new report said.

According to SamMobile, Samsung will likely unwrap the S4 Mini this week, using a tamed event for the launch. It's the company's way of dealing with the wild rumours that have been circulating about the new Android handset, triggered largely by the confirmation given to Bloomberg by a Samsung official.

As a result, the looks and the specs that the S4 Mini will display is no longer a secret and Samsung saw it appropriate to simply dance with the music and formally push out the device, the same report said.

If the plan pushes through, the post-haste revelation will be followed by a more deliberate worldwide distribution of the smaller S4, which SamMobile said will take place beginning on the last week of May.

It will be a phased release, in which selected markets will get first taste of the small but powerful smartphone while others will have to wait for a little while.

No word yet from Samsung if Australia is part of the initial destinations where the S4 Mini is scheduled to land but since the device is geared for a mass-market release, it is safe to say that neighbouring nations in the so-called emerging markets of the Asia-Pacific region are included in Samsung's radar.

Proximity-wise, it is likely that Aussies will get their hands on the S4 Mini in the immediate weeks after it hits store shelves.

Coming as the cheaper S4 Mini edition, the specs to rollout with the phone represent minor downgrades from its bigger sibling and mainly composed of a 4.3-inch Super AMOLED qHD screen display and main snapper with 8MP sensor.

The smartphone will stand on Android JellyBean 4.2.2 and draw much of its power from a quad-core Exynos CPU that spins away at a top speed of 1.6GHz, which is reserved for the single-SIM model.

For the dual-SIM variant, Samsung will reportedly use a dual-core processor but the rest of the specs will stay the same.

No definite pricing is provided at the moment but if Aussie telcos will pick up the single-SIM model for distribution, it will likely carry a price tag that is lower than the published price-with-contract of the Galaxy S4, which is $US250.
