I can't screenshot on Galaxy Ace 2

[Android Question]

Hey,

I've been reading up on all the different key press combinations on how to screenshot with your galaxy ace 2. But none of them are working for me.

I've tried pressing the home and power button at the same time.
I've tried pressing the back and home button at the same time.
I've tried weird combinations that doesn't seem like any developer would do...

Still nothing.. whenever I press home and power at the same time, I just get a new menu popping up with icons to different programs/apps.

I don't know what firmware I have right now, but since I've tried every possible combination I've read on the web, what's up?

hold Power and Home buttons for a couple of seconds, and release them at the same time. I tried this way on my Ace 2 now and it worked 3 out of 5 tries!
