Zauba is listing two versions of the Samsung SM-G750: an SM-G750H and an SM-G750F. A third variant, the SM-G750A (which is believed to be an AT&T-bound model), already has a User Agent profile that’s accessible at Samsung Mobile’s official website. The UA profile confirms the handset’s 720p display, and the fact that it runs Android.
A Samsung Galaxy S5 Mini (SM-G800) is reportedly also in the making. This should sport a 720p display, too, but measuring only 4.5-inches, not 5.1. Of course, these two names - S5 Mini and S5 Neo - aren’t confirmed at the moment. But we assume that it won’t be long until Samsung reveals some official details regarding both the SM-G750 and the SM-G800.
