@revanthkumarJ We’re looking to verify the navigation flow and ensure that navigation to all features is working correctly as expected.
Could you please upload a screen recording showing the complete flow—starting from the splash screen and login, and covering all features that have been migrated to CMP with an existing navigation route?

@biplab1 this is the latest video
For clarity what achieves in this pr:

• uncommented the code in settings module which was commented by Aditya due to some issues at that time
• implemented theming
• previously while the MainUiState loading login screen comes for 5 to 10 sec now replaced with loader
• removed the splash module after asking niyaj brother as other projects only use Theme.xml and no custom splash module is needed
• back icon navigation issue will be solved by Pronay

@itsPronay can you review once

[biplab1]

@revanthkumarJ Thanks for clarifying. Since this PR is focused on the settings module, the video makes sense for that scope.
We can revisit a full navigation flow check once all relevant features are integrated and ready for review.
