My phone has been having issues with the end call button. Sometimes it works ok, other times I have to fight with the phone to get it to end the call. Often I will hit the end call button and even though I can see the animation of a button press, nothing happens. Repeated presses do nothing, it can take up to 5-10 seconds for the call to end. I even turned on the accessibility feature using the power button to end calls, but this has the same unreliable behavior as the onscreen button. This is resulting in me having a lot of awkward end of calls and unintentionally leaving messages for people because I can't disconnect before the machine starts recording. Including a humorous one where I cussed at the phone for not hanging up and it was recorded on the machine. Has anyone had this happen on an android before, is there a known issue or fix?
