Phone: Galaxy Note 2; I605 (Verizon- Unlocked)
I have this problem with Android Lollipop where when I cancel a call, the hangup button disappears and the phone says "Hanging Up" but never hangs up. Navigating away from the dialer screen destroys the UI but the calling process still runs in the background to the point where it either goes to voicemail if the other party doesn't pick up or hangs up in case of interactive calls.
This only happens with Android 5.x.x. What could be the problem? Has anybody encountered this and what was your solution? Thanks.
