It's the worst
Working great on s7 edge.
Did not work on Note 3 Installed, tried using it multiple times. Nothing. Made certain that the app was turned on in its settings. Tried a busy number many times, gave it time to work each time. Nothing. Uninstalled.
Must have app! Very useful app.I use it for some time and I love it. Only on last update when redials it opens the speaker on first redial but not on second attempt which is a bit annoying. Samsung Galaxy S4.
Doesn't hang up automatically if busy It's missing essential function: to hang up and recall automatically so you don't have to press the button every recall which makes this app pointless as other similar apps.
Really useful Automatic redial of dropped incoming and outgoing calls on my Republic Wireless service is a great help. Call confirm is also useful for me. Occasionally fails to redial an outgoing call with or without confirm enabled, but maybe my phone's software failed to initiate it at all. (Dialing screen doesn't even come up.). Maybe it would work 100% with another carrier.
