I recently installed Orkut mobile app on my Motorola ZN5. But soft keys don’t work. So I am not able to use it. This is actually a problem with ZN5. Even some of the few games and applications I have don’t work on this. Why is Orkut mobile app not working in my Motorola ZN5? What can I do to fix it? I might add that Gmail app works fine. I would really appreciate your assistance regarding this. I hope to hear at the earliest from your side. Thanks.
