It is safe to say that Samsung's ISOCELL image sensor has been doing really well if you look at the last few years. While it is still catching up to Sony's IMX sensors in terms of the overall market share, the 64-megapixel and 108-megapixel ISOCELL sensors have been adapted numerous times in budget, as well as premium mid-range smartphones.

Samsung refreshed the ISOCELL last year and introduced five new sensors, including the 108-megapixel ISOCELL HM2, the 64-megapixel ISOCELL GW3, and a 48-megapixel variant as well. All sensors were based on a 0.7μm pixel size, but Samsung did incorporate their ISOCELL Plus and Smart ISO technologies to compensate for the smaller pixel size. At that time, Samsung talked about how they would be announcing a new pixel technology that will be called the ISOCELL 2.0 in their upcoming 0.7-micron sensors; Samsung also claimed that it would improve the light sensitivity by up to 12 percent over the predecessor and just 6 months later, Samsung is finally bringing it out.
