Hi, I just got my re-furb Samsung Galaxy S2 Skyrocket a few days ago.... I love the phone but the screen keeps going to black after 15 seconds or so. Even during phone calls which is annoying because then I can't use the touch screen to end a call unless I manually turn the screenlight back on.

I went into settings/ display and chose "10 minutes" for the screen timeout.

Then I went to power saving mode and selected "power saving on at 30% battery power."

My battery is fully charged but this is happening constantly.

So my question is -- am I doing something wrong? Or is there something wrong with the phone? Is this normal?
