Symbols may appear differently across the different devices and operating systems you use to access your LinkedIn profile. That means what you see isn’t necessarily what another person sees when viewing your profile. Smartphones tend to take symbols and convert them to emoji. Emoji are small, colorful icons that are typically used to express ideas and emotions.
If you are viewing your LinkedIn profile on a PC, the symbols in your headline may appear black. Viewing your LinkedIn profile on a smartphone or on a Mac desktop, the symbols in your headline may appear colorful and almost cartoon-like. iPhones and Android phones use different art and so the symbols may look different depending on your smartphone.
When choosing symbols to populate your LinkedIn profile, the simpler the better. Stars, circles, squares, arrows, and check marks are universal and display with consistency across almost all devices. Using more complex symbols like those of folders, books, phones, paperclips, tools, and other items, you risk the symbol either showing differently on some devices or not at all.
