After several stealth appearances on the Samsung App website and Samsung support website, the Samsung Galaxy S4 mini may be set to make its official debut in about three weeks. The Wall Street Journal reports that the truncated version of the Galaxy S4 could be unveiled at a product launch event in London on June 20.

The Samsung Galaxy S4 mini has all but been confirmed since March, when images of the device next to a Galaxy S4 and Galaxy S3 surfaced, and while other clearer leaks have showed up in recent weeks. The Galaxy S4 mini will be Samsung's second attempt at a smaller and cheaper version of its flagship devices. After the Samsung Galaxy S3 mini was introduced last year, enthusiasts were certain that a Galaxy S4 mini would quickly follow the unveiling and release of the Galaxy S4. 

Tipsters told the WSJ that the Samsung Galaxy S4 mini is among many devices set to be unveiled at Samsung's press event, which will take place London’s Earl’s Court exhibition center, and that new devices include some that will run the traditional Android operating system and others that will run the Windows operating systems. We may see the Galaxy Tab 3 10.1 and Galaxy Ace 3 unveiled at the event, along with other devices in the Galaxy S4 family, including the Galaxy S4 Zoom camera, the rugged Galaxy S4 Active and perhaps another Galaxy S4 variant, according to SamMobile and Android Authority. 

Samsung has also teased the Samsung Premiere 2013 Galaxy & ATIV event on its press website, but the company has not given much detail on what fans can expect. Meanwhile, rumors for the Galaxy S4 mini heat up. Initial predictions suggested the Galaxy S4 mini would feature a dual-core Exynos 5210 CPU and 1GB of RAM, with its LTE version packing 2GB of RAM. However, a recent leak from an AnTuTu benchmark, supposedly testing the Galaxy S4 mini, suggests that the device will feature a dual-core Qualcomm Snapdragon 400 clocking in 1.7 GHz, a Adreno 305 graphics chip and 1.5 GB of RAM. 

It remains a common expectation that the Galaxy S4 mini will feature a 4.3-inch Super AMOLED display and a 8-megapixel camera, and that it will run Android 4.2.2. However, we don't expect any of these rumors to be confirmed or denied for another three weeks. If unveiled in June, the Samsung Galaxy S4 mini will likely be right on track with its rumored July release date.
