A new update to the Skype for Android app is rolling out, bringing end-to-end encryption for conversations and other improvements. The update is version 18.104.22.168 for those keeping score at home and should be available to everyone in the Play Store by now.
The big new feature in this update is what Microsoft is calling Private conversations. It is end-to-end encryption for your conversations that you have within the message app. By encrypting it, you don’t have to worry about your text or video conversations being intercepted. If they are, they are encrypted and protected. It is a key feature that is important in this day and age for messaging apps.
