With the Galaxy S5 set to make its retail debut in just over a week, Samsung can now turn its attention to the flagship’s smaller sibling, the Galaxy S5 mini.

The handset is expected to make its debut in June, and according to inside sources familiar with Samsung’s plans, it’s going to feature a 4.5-inch 720p display, an 8-megapixel rear-facing camera, and 16GB of internal storage as standard.

Samsung has inadvertently leaked an unreleased Galaxy smartphone with a quad-core Snapdragon 800 processor on its website. It’s thought the handset could be a Galaxy S5 mini — or even a cheaper Galaxy S5 Neo with older internals.

The Samsung Galaxy S5 is fresh from its announcement last week, but a new rumor claims that its mini variant is already in the making. According to an Indian import listing, a device with the model number SM-G870a has been spotted.

Earlier today, we revealed that Samsung is expected to unveil its flagship smartphone of 2014, the Galaxy S5, in London sometime around mid-March, and not at the Mobile World Congress in Barcelona next month as previously rumored. Now a Samsung-orientated publication has posted a list of ‘confirmed’ leaked specifications on the internet stating some of the impressive internals the device is purported to pack.
