dionisdei, Dec 1, 2017 : I've read in a thread about the double calculator app, I only have the OnePlus app installed, just wanted to get that out of the way. My problem is that the scientific calculator is always on, and I don't use it all that much. I've attached a screenshot. I've seen examples where the scientific calculator only appears when you rotate the device in a landscape position, but mine is always on. Is there a way to hide that section of the calculator?
