The mass and popularity acquired by emoticons has generated a new way of communicating moods, feelings, reactions and even complete sentences. However, despite having the same Unicode encoding, its interpretation is subject to different cultural contexts depending on the environment of the person who uses them, especially when the different platforms have their own design. This is the case of the phone hand.
This emoji consists of a closed hand with the thumb and little finger extended, making a traditional telephone shape. The icon can be used together with a face to request “call me” (please).
It is important to mention that it is not the symbol of the horns or the sign of shaka or “hang loose” (which does not have an emoji representation at the moment). However, some users have attributed this reference to the typical greeting of Hawaii and surf culture. In these cases the hand is raised or waved to emphasize the gesture.
“Call me Hand” was approved as part of Unicode 9.0 in 2016 and was later added to Emoji 3.0 that same year.
Many times when people are in a hurry and quickly leave a place without saying goodbye, they tend to make this shape with their hand indicating to the other to call them. The same can be applied by a user in a WhatsApp conversation , if the user is in a hurry, he can save several words by putting the hand icon on the phone to tell his friend to call him later.
