This phone here appears to be yet another miniature version of a popular full size model, with official filings revealing something we suspect might end up being known as the Samsung Galaxy S4 Active Mini. Could do with a smaller name too.
The phone popped up in regulatory filings on Chinese site Tenaa, which describes it as the Samsung GT-I8580. Visually, it looks like the chunky Galaxy S4 Active, what with its return to physical buttons and a fairly robust (and cheaper looking) case. Aside from that there's little to go on, although that model number has previously been associated with a benchmarked phone featuring a 4.65-inch display with a low-end 480 x 800 resolution.
