They wont be, moreover in screen sensors are totally useless, and inconvenient things. I need to directly put my finger on it, while on my old phone the sensor was on the back side, where i naturally hold my phone! So i didn even need to think about unlocking my phone when i took it in my hand, to use it, ive unlocked it. This cant happen with screen sensors, as those arent there where you touch your phone, and the screen above it will always limit its capabilities.
