It seems like Samsung is making plans that go far beyond its flagship devices for 2014 as a recent news from a Korean tech. website suggests that engineers at Samsung are already working on a 20 megapixel camera module. The Galaxy S5 which is supposed to debut in January 2014 has already been indicated to use the 16 Megapixel ISOCELL camera unit so there is a good chance that this 20 megapixel module is not intended to debut on a device any time soon or even in 2014.
Also keep in mind that Samsung Galaxy Note line uses the same camera unit as the Galaxy S line flagship, so there are none to few chances of this 20 megapixel module to debut in the later half of 2014 when usually the Note line of devices comes in. To add to this there have been previous rumors which suggested that Samsung wouldn’t be increasing the megapixel count on their cameras by a considerable margin. On the other hand, the rumors about the Samsung Galaxy S5 to be missing OIS (optical image stabilization) in its 16 megapixel module is another issue that is yet to be sorted out, the reason being that Samsung needs at least 50 million (Sale figures of Galaxy S3 & S4 have been above 30 millions each) OIS modules if it intends to make it a Galaxy S5 feature, but unless the company can make its own modules, (which is too much production pressure) it isn’t possible.
