I have a samsung galaxy ace.Sometime when I press middle button it captures & many times dosen't....
So, can anyone here tell me how to capture screen....?
Well try (quickly) pressing the power button ( just once ) and then press the home button. If that doesn't work just go download a screen shot and then after you have it set up and going all you do it press the power button and the home button, :D But first the power then the home :P quickly LOL
Screen shot app at the play store *
