[Bug 1524648] Re: Display doesn't turn on for incoming phone call

 

OK I get what the problem is: it's the proximity sensor.  I have a flip-
case for my phone that covers the proximity sensor.  If the flip-case is
closed the phone thinks it's next to my ear and switches off the screen.

So there are two things wrong here.  First (IMO) it doesn't make sense
to use the proximity sensor to control the screen when the phone call
hasn't been answered yet.  Second, the phone should at least switch the
screen on when I open the flip case, but it doesn't.

I tested it with four phone calls just now:

1) Flip-case closed.  Didn't switch on screen.
2) Flip-case open.  Screen turned on fine
3) Flip-case closed, then opened once it started ringing.  Still didn't switch on screen.
4) Flip-case open.  Screen turned on fine.

syslog attached.

  Display doesn't turn on for incoming phone call

Bug description:
  I just received two phone calls.  In each case the phone started
  ringing but the screen stayed black.  In the first case I let it ring
  for a while hoping that it would magically wake up, since some bugs do
  seem to work that way.  But nothing happened.  I was unwilling to
  press the power button since in iOS that immediately hangs up the
  call.  Eventually however I did press it, and the screen woke up.  But
  I was too late to answer the call.  When the person phoned back the
  screen was black again, so I pressed the power button and was then
  able to slide the slider to answer the call.

  I don't think this is the same as Bug #1493574, since that bug seems
  to happen after the phone has been answered.

  Syslog of about the right time attached.  Phone reports the times of
  the calls as 15:41 and 15:47.
