Okay, this may be a long shot , so a grain of salt, we recommend ourselves to this already. But it might just be that a device with the model code SM-G870, being tested in India, soon the Samsung Galaxy S5 Mini turns out to be.
In the infamous Indian import database Zauba dives at least one device with the model code above: SM-G870, G870A-SM or to be exact. The ‘A’ refers again to a provider-specific device variant – in this case the U.S. carrier AT & T.
Further information is still lacking at this time, and becomes the only clue is the estimated value of the equipment. This is roughly two-thirds of other Galaxy S5 variants that pop up in the same database. A brief look at the past shows that Mini variants of top models always popping up with the same value ratio Zauba – as was the case with the Galaxy S4 and S4 Mini.
