System and Application Theme

Is your feature request related to a problem? Please describe.
System theme and Enatega Application theme is contradicting with each other.

Describe the solution you'd like
When the user install the enatega application and uses it, the application should be able to pick whichever theme system is already using.

No file or test is named. Start by locating where the Enatega application's theme is configured and how the Android system theme is handled, then compare the current system and application behavior. Done means the application follows the user's existing system theme without the two themes contradicting each other.
