Skype for Android updated to version 5.5; new features make it easier to sign-in
As you might imagine, this could create a security issue for those who like to lend their phone to others. As a result, the settings can be changed to require someone using Skype to fully sign-in every time they want to use the app. To change your sign-in preference, go to settings and then click on privacy.
Another new feature that will slowly be rolled out over the next few weeks, will allow a web link preview to be seen in a chat whenever a web link is typed in. This is something that iOS and Mac users have already enjoyed. The advantage to seeing the preview is that it gives you an opportunity at a glance to see whether the link is worth clicking on in the first place.
If you already have installed Skype on your handset or tablet, you can receive the update by going to My apps at the Google Play Store.
