Accessing information while on a call is easy enough on your Samsung Galaxy S9. When the call is in full screen mode, you can tap a number of icons. When you need to contact information stored in your contact database, you simply swipe the screen to the left and tap on the Contacts icon. Your Contacts app open, and all the information you have is right there.
Likewise, if your friend Jim insists that there is no indication that Humpty Dumpty was an egg, you can bring up your favorite search engine to check whether Jim is correct.
In addition to Contacts or the Internet, you can quickly get to your e-mail, texts, calendar, or a memo pad.
