I have a Samsung Stratosphere phone.
I tried the Power + Home button & although I get the "snapshot" sound, and a white border that flickers a moment, it comes up & says, "Unable to capture screen. Try again." which I do. Multiple times. No joy. And if I DO get it to take a screenshot, where does the file reside?
Thanks!
Okay....figured it out. But thought I'd leave this up in case someone else ran into this. I had my USB plug inserted. Once I unplugged it, the screenshot feature ran fine.
And easy enough...screenshots in a folder called...."Screenshots".
Thanks for the tip!!
