I have seen that the behavior gets activated since 4.0-rc1
https://github.com/torvalds/linux/commit/b0dcaf4fbb36895175657be029ed64eda2a34707

I have downloaded Mainline 4.0-rc6 and testes but it did not work. Then I found out, that the author did not activated the behavior for all Samsung laptops. https://bugzilla.kernel.org/show_bug.cgi?id=75901 shows the commands to enable this behavior:
cd /sys/kernel/debug/samsung-laptop/
echo 0x81 >d0
echo 0 >d1
echo 0 >d2
echo 0 >d3
echo 0x6e > command
cat call

Then I can close the lid and it goes sleep instantly. After lid open it wakes up from sleep.
This has to be enabled by default for my laptop.

Title:
  [Samsung 700Z3A-S02DE] Laptop does not resume from suspend upon lid
  open

Status in linux package in Ubuntu:
  Triaged

Bug description:
  In 13.10-14.10, what is expected in to happen is when I close the lid,
  it puts the computer to sleep, and when I reopen the lid, it
  automatically resumes from sleep.

  What happens instead, is that the computer goes to sleep, but opening
  the lid does not make it resume.

  With acpi_listen I see that it fires and recognizes the events for lid close and open. /proc/acpi/button/lid/LID0/state shows the correct state for each lid position. With:
  acpid -d -f -l

  I see that those events trigger /etc/acpi/events/. I tried writing an
  event that matches lid close/open and calls pm-suspend, uncommenting
  lines in /etc/systemd/logind.conf regarding hibernate and suspend,
  echoing LID0 into /etc/acpi/wakeup, passing different acpi_osi strings
  with grub but the ACPI table does not change nor make it any
  difference for the suspend/resume problem.

  WORKAROUND: To resume, open the lid and press the power button once.
