Finally starting to understand how the tablet works, but still a great deal to understand / learn. I noticed that when the tablet is in the case, it blocks the speaker in the back. My friend called me on skype, i was able to see / hear her clearly, however she was not able to see me ?? She was able to hear me o'k, but no video of me, just intermittent she saw me momentarily 3 times, not sure what i am doing wrong ??
