This is the WhatsApp hack that everyone need to know if you want to avoid public embarrassment.
Listening to WhatsApp voice-notes in public can be an embarrassing task, with many people preferring to avoid sending or receiving them as they can't listen to them until they're somewhere private. For most people, playing voice-notes in public and holding the bottom of your phone, where the speaker is, up to your ear to listen is the ultimate public faux pas.
This hack avoid the issue, as you can actually hold your phone to your ear as you normally would during a phone call to listen to voice-notes as well. One woman has gone viral on Instagram explaining the hack.
