Doesn't work properly on Marshmallow It was working fine on lollipop and I loved it but recently with my lenovo upgraded to Marshmallow the app doesn't work at all. Opens and crashes. Tried reinstalling but no luck.
Very bad now Update: the app puts it self on hold when receive incomming call. No option to cancell on hold. Impossible to answer any call. Very bad . I paid for the app years ago and then it was ok. Please fix it or I want my money back!!!
App has stopped working Intermittent operation, missed calls, really disappointed, looks like developers have moved on. It used to work great on Nexus 4 but no longer the case in Nexus 6
In the current version (4.8) push notifications are not waking the phone up from sleep in android 6.0, either in wifi or 3G. Tech support has been prompt and diligent, but when all was said and done the problem still exists, they say it is a known issue to their development team and will be fixed in the next release. For me, push notifications are the only selling feature of this app over more customizable (and free) voip apps like CSipSimple. Until this problem is fixed, save your money and stick with the free alternatives.
Samsung Galaxy Note running Android 5.0. Proximity sensor does not work anymore after the latest update. The saddest thing the other party can't hear you anymore on GSM connections.
