The encrypted messenger app Signal - an app which has become more and more popular over the last couple of months, has begun testing experimental voice and video calls in its beta programme, in preparation for adding the feature to the stable app. This follows the lead of Facebook-owned WhatsApp and Messenger, as well as Google Duo, in a trend of companies focusing on video calling recently.
Changes in the latest version:
Experimental support for next generation video and voice calling. To enable, toggle Signal Settings -> Advanced -> Video calling beta. Calls to or from contacts who also have this setting enabled will use the new next generation calling feature and support video. The upcoming Signal iPhone beta release will include the same functionality.
You can enable experimental features in the beta version of the app, available on the Google Play Store. These are available in settings, and include voice and video calling. Both the caller and the recipient need to have turned on video calling for it to work, in which case an encrypted, secure video call can be carried out, away from prying eyes. The upcoming iPhone beta release of Signal will also include this functionality.
