The Samsung device that goes by the model number SM-G750 has popped up again on an Indian import database site Zauba. We've seen the model number before and speculations suggest it could turn out be the Galaxy S5 Neo. In its previous leak it sported a screen resolution of 720 x 1280 pixels and an 2.3 GHz CPU.
Though the new leak we gather some new information - the screen size is slated as a 5.1" - the same as the Galaxy S5. The SM-G750 is listed as SM-G750A, SM-G750F and SM-G750H - probably regional options for different markets.
Sadly that's all the info we get at this point. Hopefully the Galaxy S5 Neo goes official and we get some solid information soon.
