I'm abroad at the moment, using my Samsung Galaxy Tab 2 to keep in touch. When using Skype for the first time yesterday, to contact my daughter in UK, she could see me but not hear me. I could see and hear her okay.
At the bottom of my Skype screen the audio symbol had a red line through it, but when I toggled it to 'on', the video symbol got a red line through it! I couldn't get both 'on' at the same time. Could this indicate a shortcoming in the WiFi/internet connection I'm using, or a setting I haven't found in Skype or my tablet?
