The second image shows the same smartphone with a black screen and a blue background. The screen now displays a different app interface with a black background and white text. The app's title is 'HEX CODE', and there are several buttons and icons, including a 'Touch to Copy' button. The time at the top of the screen is '12:00'. The bottom of the screen has a 'Settings' icon and a 'Help' icon. The overall design of the app is more complex and has a different layout compared to the first image.
