Samsung Galaxy S8 model numbers revealed, new Galaxy Note (SM-N950) reportedly in the making
Since the Galaxy S7 and Galaxy S7 edge have the model numbers SM-G930 and SM-G935, respectively, one would assume that the S8 series will include SM-G940 and SM-G945 models. However, it looks like this won't be the case.
Evan Blass (renowned for being almost always accurate in regards to unannounced devices) says that the upcoming Samsung Galaxy S8 smartphones "will ship as SM-G950 and SM-G955."
More interestingly, Blass also mentions that Samsung is working on an SM-N950 - which can only be a new Galaxy Note (since previous Notes have the model numbers SM-N930, SM-N920, and so on).
