So, while debugging this issue I found the following:

The delay seems to be bigger if wifi is disabled. If wifi is enabled,
after 1:30 at most the device wakes up, and if no wifi, device seems to
remain off indefinitely (I waited only for 10 minutes then gave up). In
my case, it's krillin and I have only one sim in the second slot. At
first I thought that could be lack of entropy and the system would be
stuck trying to read from /dev/urandom, but turns out this is what I
found:

1) oFono delivers the message to telepathy-ofono right away.
2) telepathy-ofono informs telepathy about the new message.
3) telephony-service-indicator gets the message, sets a timer (QTimer::singleShot()) of 1.5 seconds before displaying the message (that's to avoid displaying notifications for messages that were already displayed in messaging-app.

4) Then I noticed that the triggered() signal is never emitted, until I
manually force the device to wake up.

5) running an strace on telephony-service-indicator and (leaving the
device stuck for about 1 minute) I get this:

[pid  2231] 1474573884.069934 clock_gettime(CLOCK_MONOTONIC, {1265, 272122461}) = 0
[pid  2231] 1474573884.070193 clock_gettime(CLOCK_MONOTONIC, {1265, 272383307}) = 0
[pid  2231] 1474573884.070407 poll([{fd=3, events=POLLIN}, {fd=6, events=POLLIN}, {fd=7, events=POLLIN}, {fd=10, events=POLLIN}, {fd=11, events=POLLIN}], 5, 1571) = 0 (Timeout)
[pid  2231] 1474573951.500698 read(3, 0xbed2817c, 16) = -1 EAGAIN (Resource temporarily unavailable)
[pid  2231] 1474573951.500977 clock_gettime(CLOCK_MONOTONIC, {1266, 845932613}) = 0
[pid  2231] 1474573951.501380 clock_gettime(CLOCK_MONOTONIC, {1266, 846369074}) = 0


Someone please correct me if I am missing something, but from my understanding qt is stuck in the event loop waiting for the timer event, which only happens after I press the power button.

What worries me here is that the call to poll() explicitly sets the
timeout for 1571 (1.5 seconds), and -apparently- it only timed out after
67 seconds, which is when the next call to read() is executed.

An additional information is that on dbus I always see indicator-
datetime emitting a signal (Changed()) as soon as telephony-service-
indicator also gets unblocked, which is a strong indication that
indicator-datetime is also getting affected by this.

Bug description:
  WHAT HAPPENED:
  The phone stays quiet while locked but once the power button is pressed (unlocked), SMS notification are received with vibration, notification bubble and sound alert. The message received shows that it was actually received 10 minutes ago.
  This happened multiple times already but I think I ignored them and this seems to have started after OTA-7 was released.

  
  EXPECTED:
  The phone should have the vibration, notification bubble/indicator and sound alert even if the phone is locked.
