Hi, I'm a OnePlus 6 user. The phone has an AMOLED display panel. Which means pixels get turned off whenever the pixel is black, in this case when the theme is black, which helps save battery and give a darker black. The initial 3.0 (nightly) release had a black theme but in a recent update it was changed to dark. Can you bring the black theme back and keep the dark theme as well. (like an OLED only option) Thank you!
