Recent apps
Samsung has put its own swing on this app switcher business that most manufacturers leave unchanged and similar to the stock Android implementation. As a result, you get a more condensed implementation of the recent apps, whereas LG is mostly relying on whatever Google designed in stock Android. We can't really find a fault in that.

Phone
The Phone app on both devices is quite intuitive and modern-looking, making it super-easy to find your way around and have all the essential features at your fingertips.

Messaging
What's notable here is that LG has opted for a splash of color that makes the interface appear a bit more modern, whereas Samsung's implementation relies on a predominantly white interface.

Folders
Both devices feature full-screen folders that fill up the screen and are quite aesthetically pleasing. There are quirks with both - the Galaxy S9 features a nifty "Add apps" button on the bottom, whereas the LG has such a button right near the folder name field.

Settings
Traditionally, LG separates the standard Settings menu of Android into four separate tabs that make it a bit easier to get to the desired option, and that's just exactly what you see on the LG G7 ThinQ. General, Display, Sound, and Network tabs make this normally-convoluted menu a bit more intuitive to get around. Samsung, on the other hand, has opted for a more succinct settings menu, with many features and functionalities hidden away and requiring you to use the built-in search function a bit more often.
