Just like the sticker feature of the poll, the emoji slider allows the user to ask a friend. The difference is, in this feature users use emoji as an answer.
"Emoji slider allows users to ask with a more interesting style, so you can know the feelings of friends about something," wrote Instagram on his official blog.
To bring up the slider emoji, it is not too difficult. You just need to type the camera-shaped icon located at the top right. Then select the photo to use as the background.
The next step is to choose the emoji slider feature located inside the sticker menu. Then, write the question you want to ask and select the appropriate emoji. If you are sure, you just need to share the question with friends.
As the poll runs, users can see the reaction of friends who answered your question. So you can find out who answered the question.
"When you see emoji sliders in stories, just drag the emoji left and right," they continued.
The emoji slider feature can be used by Android users on iOS and Android. However, you should make sure it is using Instagram version 44.
