I have set up the security features & am attempting to test the remote locate feature, but it doesn't appear to be working correctly. I receive the commend text on the "lost phone", but do not receive a location response on the phone that sent it (which I have confirmed is set up as one of the authorized numbers).
I am also having this issue. It seemed to be working up until this last update. I am running a custom ROM as I was previously. I don't use the native message app either, I use Handcent.
unfortunatally we cannot support all custom ROMs. SMSec needs to have access to the SMS and the 3rd Party Message App together with the custom ROM might block taht access.
I have the same problem on both my phones, Samsung Galaxy S2 and HTC One X, both ICS and stock ROM. I am sure I used the correct password. I hope you resolve this issue, because the main reason I got this app was because of this feature that I can't use now.
