The Galaxy S10 is widely expected (pun intended) to sport three cameras on the back, and today Korean media reiterates this notion by hashing out the exact sensor resolution of its triple-camera set. We say pun intended because the S10 is supposed to land the Holy Grail of lens technologies in one handset - a main 12 wide-angle camera, a super wide-angle 16MP one, and a 13 MP telephoto cam for what will likely be at least 3x optical zoom efforts.
