You may also want to try recording sound with one of the free voice recording apps in order to make sure it is not an internal problem with the microphone.
Check to make sure that "mute" is not turned on while making a call. If "mute" is on then you would be able to hear others but they wouldn't be able to hear you. Hope this helps.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
