Been using it for many years, Skype on different platforms. PC Mac and iOS all the best, useless on the Kindle Fire HD, as you have over virtually can not understand: inaudible despite full volume. However, the interlocutor understands everything perfectly (iPad, iPhone). In addition, nerve frequent crashes that are not even there developed on another platform so.
I am very disappointed by the lousy implementation on the Kindle: the Skype functionality was the only reason for acquiring the Kindle Fire HD!
Unbelievable how a functioning program can vermurksen so, please fix quickly!
