Two Samsung IMEI numbers have surfaced that point to two new Galaxy models. Their model numbers are SM-G928S and SM-N920F and the rumor mill has decoded them as the "Zen" Galaxy S6 Plus and "Noble" Galaxy Note 5 respectively.
The SM-G928 appears to be a variation on the Galaxy S6 (G920), but it's unclear what will change from the current model. The final letters reveal regional versions, F for Europe, A and V for AT&T and Verizon, S and K for SK Telecom and KT.
The SM-N920F we couldn’t find and its name does coincide with what the next Note should be – the Galaxy Note 4 is the N910. Unfortunately that doesn’t give us much, neither does the "Noble" codename.
The letters indicate a European version, plus one for each carrier except KT.
