I'm trying to sideload an application, as seen in the picture below.
I have allowed the installation of applications from unknown applied actions in settings, but I can't seem to press the install button. The cancel button works correctly and installing applications via
adb install works correctly. What's the problem?
EDIT: For those who have this problem, using ChainFire's C.F. Lumen will correct it because the app uses hardware compositing, and Android doesn't notice a "layer" on top of the current screen.
