Samsung might have a lot of resources when it comes to producing mobile components, even putting together Apple's iPhone processors, but when it comes to camera sensors, Sony pretty much has a monopoly over the market of 13-megapixel sensors, with even Samsung's Galaxy S4 and Note 3 using Sony's sensors.
For the Galaxy S5, Samsung is expected to use a 16-megapixel camera, and according to a new report, Samsung LSI (part of the Samsung Group) and Sony are now locked in a race to be the one that produces those 16MP sensors for Samsung's upcoming flagship device. Samsung will begin sampling S5 camera components next month, and should make the decision on them by the end of the year.
Using its own sensors would have multiple advantages. For one, Samsung would be able to better control its quality and features (such as the recently announced ISOCELL technology for better low-light photos), and secondly, it would also reduce the cost of acquiring these sensors. Nothing is certain right now, but if Samsung is able to produce enough of 16MP camera sensors, then we can all expect the Galaxy S5 to be even better than the already great camera of the S4, so keep your fingers crossed.
