Samsung seems to be working on more than just new Galaxy S5 variants, if a tweet by @evleaks is to be believed. According to the notorious leakster, a new device with model number SM-N910 is headed to AT&T in the U.S. – there's no device name mentioned, but judging by the model number, it seems to be a variant of the Galaxy Note 3 (SM-N900). This is certainly not the Galaxy Note 4, and probably not the Galaxy Note 3 Neo either, as that phone carries model number SM-N750 internationally, which means there's no telling what the SM-N910 might turn out to be.
Evleaks also suggests that an SM-G860 is headed to Sprint as the CDMA variant of the Galaxy S5 Active, which is expected to sport model number SM-G870 on AT&T. Furthermore, the Galaxy S5 Neo, one of the gazillion Galaxy S5 spin-offs Samsung is said to be working on, is reportedly on its way to AT&T along with the SM-N910. All in all, it looks like the Korean manufacturer will be bringing an avalanche of new devices to two of the US' largest carriers, though there's no word on when these devices will go official.
.@YanksFan371 Likely a CDMA variant of the G870, which is the Active or Sport version of the Galaxy S5.
