I have Cricket wireless. Downloaded the Visual Voicemail app. When listening to a voicemail, screen went dark and locked up the Nexus 6p. Had to do a hard reset to get phone back up. Tried again and got same result. Uninstalled the app. Is this an app issue with Android 6.0.1? I can live without the app although it had some useful features. Just looking to see if my issue is isolated.
