Ratings and reviews

The app is now much more better after this update, but this would be more better with dark mode which is missing. Also there is no notification or ringing of any incoming calls from non-kothon numbers or other IP calling apps. only I can call in any number but when they call back in my kothon number, it never notifies me. Please add incoming call ringing like amber it, brilliant, alap and other IP calling apps.😊
