Flash Notifications color dialog crashs if configuration changes
Root Cause:
When configuration changes, it will recreate fragment then call no args constructor which lead to null pointer exception for error passing parameters in getInstance().
Solution:
* Use setArguments() to pass parameters.
* Move settings key update action into fragment.
* Obsever settings key changes to update summary accordingly.
