This was revealed via an email allegedly from the WhatsApp team to a Hong Kong developer, asking the developer to help the company translate several new strings into Chinese. The strings, according to the email, include Camera button on/off, and a push-to-talk button. Of course this email could have easily been faked, but adding push-to-talk functionality isn’t exactly groundbreaking, plus it would give users a reason to stay with WhatsApp instead of switching to push-to-talk apps such as Vox. Take this with a grain of salt for now, but what do you guys think of push-to-talk coming to WhatsApp? Is this a welcome feature?
