There are a lot of rumors that we have already heard regarding on Samsung Galaxy A8. One of them is that the new device will have 5.7-inch metal phablet with 5.9mm thickness which makes it the thinnest smartphone that Samsung has ever manufactured up to date.
The only question which remains is which camera sensor should be used to make the device thin but still be able to take a good quality of picture. Samsung Galaxy A8 promises a 16MP camera sensor, however, if we are about to integrate 16MP Sony IMX240 and Samsung ISOCELL sensor which is used in Galaxy S6 and S6 Edge, the device thickness cannot remain as 5.9mm. Therefore, to solve this issue, Samsung will still be using an ISOCELL sensor, however the slightly downgraded version. Samsung will be using the new module with model LSI3P3, which has a reduced pixel size of 1.0 µm. With this arrangement, it makes the camera sensor 23% thinner than the Sony camera and thus it can be fitted into Samsung Galaxy A8 and the thickness of 5.9mm still will be able to be achieved.
However, with the reduced pixel size, there is no guarantee how much impact it will have to the quality of picture produced. It might not have any impact at all. We just have to wait until the official announcement of Galaxy A8 which is most probably going to happen pretty soon.
