Right after I installed Skype, it says that the HTC One X isn't yet certified to work. And other stuff about you may experience with quality problems ans such. Hopefully they get an update out for it, but since it's already certified for the Lumia, idk why they havn't certified the One X.
I am having similar issues with Skype. I bought my HTC One X two weeks ago and so far the experience with Skype has been horrible: scratchy voice quality, sometimes it doesn't see my contacts, sometimes I cannot sign in and now the call fails as soon as either of the parties on the call picks up. I see many complaints for similar problems in various web sites but no solutions. Does anybody know anything about this problem?
