I have an Acer Aspire One Happy. I have a built in webcam which I apparently can use through Android. When I click on the camara icon all the camara will show is a black screen. When I click on the top right hand button to take a picture it just takes a black picture. My webcam is not covered. Can you use the webcam to take pictures - my son has an Acer laptop and takes his picture all the time with it ( he has Crystal Eye. I dont even know if my webcam is crystal eye???) - or is it only used for Skype etc. Thanks
