Samsung could introduce an extra-large Android tablet in the second half of the year, according to ETNews (translate).
According to the Korean Web site's "industry sources," the Samsung tablet will feature a 2,560x1,600-pixel display and come with an S-Pen stylus. While there's no outright mention of a name, we could assume it'll be part of the Note line.
As for smartphones, the Samsung Galaxy Note 3 is, so it stands to reason that Samsung could debut a larger, 12.2-inch model at the same time.
As I see it, one likely scenario is that Samsung hosts another Unpacked event to coincide with IFA in early September.
