I installed avast! anti-theft app on my galaxy phone and setup an account, restarted the phone. Then I went on to web and login, located my phone ok. But when I clicked on the siren "send" button, it did not give me any response. I had to click the "cancel" button just next to it so that the dialog box goes away. Tried to send siren command this way multiple times with no success.
The phone is not rooted, and the phone only has wifi connection (not in cellphone network). Please let me know what's going on.
Btw, I remember seeing that after the phone restarts, the avast! app will hide itself. But I still see it there with the icon on top, in the manageable applications, and in the app list.
