The app is very bad, it does not show when I receive a call, it just becomes blank but funny thing is that it rings , its really frustrating because I am missing out on a lot of important calls and at times I don't have means to call the person who called me back. It only shows calls as missed calls. At this point I don't know what to do anymore coz this thing is really frustrating me I've heard enough of this app should I maybe unstall e app and re-Install it at this point I'm out of options.
