@odamizu Yes I am. The only way to make brightness work only within an app is to overlay a translucent black layer on top of everything. This means that while the app will *appear* to be dimmer, the device will still be operating at full brightness, hence using up more battery life. There are other colour shifting, and user confusion issues that must be considered.

Regarding your second point - that's the way Apple designed iOS to work. Every app that allows for the control of hardware brightness will do that. You'll find this documented in Apple docs.
