On Snapchat, the "best friend" feature used to display the emoji next to the names of your closest friends based on the frequency and intensity of your interactions with them. However, please note that Snapchat had removed the public "best friends" list, and the best friend emojis were no longer visible to other users.
Instead, Snapchat introduced a private "friendship profile" feature, which allows you to see your individual streaks and other insights about your interactions with specific friends, but this information is private and not visible to others.
If you're looking to identify your closest friend based on interactions within the app, you can check your "Friendship Profile" with that specific friend. Here's how you can do it:
Open Snapchat and go to the camera screen.
Tap on your profile icon in the top-left corner of the screen to access your profile.
Scroll down, and you should see a section called "Snap Map" and "Friendship Profiles."
Tap on "Friendship Profiles," and you will see a list of your friends.
Find the friend you want to check, and tap on their name.
You'll see details about your interactions with that friend, including your Snap streak, mutual friends, and more.
Keep in mind that the absence of a public "best friends" list means that you can maintain your privacy regarding your interactions with different friends on Snapchat. Remember that friendships are not necessarily ranked by who you interact with the most on social media, and real-life interactions and emotional connections are more meaningful indicators of close friendships. So, focus on nurturing your relationships and spending quality time with the friends who are most important to you, regardless of the emoji or public display on social media.
