Samsung touted a Samsung Galaxy S4 Mini launch after the Galaxy S4 release, and it now seems the miniature flagship inches closer to arrival.

The U.S. launch of the full-size Samsung Galaxy S4 had everyone on their toes for the past four months and now Samsung finally announced the official availability for its newest flagship smartphone. With that out of the bag, attention is now turning to the Mini version of that handset.

The Galaxy S4 Mini seems to be nearing its own launch, as the device's purported model number just made an appearance on Samsung's website (XML) in the form of a user string agent, detailing several of the rumored specifications for the handset.

The smaller version of the Samsung Galaxy S4 follows the same pattern as the Galaxy S3 and its Mini version, which arrived in the U.S. and other regions last year. While Samsung did confirm it has a Samsung Galaxy S4 Mini in the cards, it did not reveal what the handset packs on board or when it will actually make its debut. Thanks to leaks and rumors, however, the smaller Galaxy S4 is no longer such a mystery.

According to the latest Samsung Galaxy S4 Mini leak — the user string agent first discovered by Dutch site TechTastic — the device has the model number GT I-9190: the presumed model number of the Galaxy S4 Mini. While the user string agent is not a clear indication of an imminent launch, it does point out that Samsung is preparing for the smartphone's arrival.

The leak further reveals some phone specifications, including a processor based on ARM 11 architecture and a qHD display with a resolution of 960 x 540 pixels. Previous whispers, meanwhile, suggested the Samsung Galaxy S4 Mini would sport a 4.3-inch display with a 960 x 540 resolution, an 8-megapixel camera, Android 4.2.2 with TouchWiz Nature UX and perhaps even a quad-core processor of the Exynos kind.

With the regular Samsung Galaxy S4 making its way to U.S. shores in April, the smaller version of the handset should arrive sometime in May or early June.
