Rebtel users on Android have certainly been getting their fair share of updates this month. Late last week, the app was updated to include a simplified sign-up process.

The latest version changes the “0” at the end of the version number to a “1” and fixes a proximity sensor bug that was plaguing some Rebtel users whenever they attempted to make a call and also while they were on a call. This bug caused the screen to flicker at inconvenient times, and so far it appears to be fixed on our devices. If you still experience this issue, be sure to post in the comments.

Rebtel includes some very unique features when compared to other calling and messaging apps. One of the most notable of these features is “Keep Talking,” which allows users who are chatting with friends or family over Wi-Fi to switch and use their mobile network at a moment’s notice by prompting the user to touch an on-screen button. This feature keeps users connected to their Rebtel calling conversation even when they leave a Wi-Fi coverage area or experience a degraded connection.

If you haven’t already, you can download Rebtel 2.8.1 in the Google Play store.
