Im on antitheft version 2.0.4838 and getting the same problem....web commands work fine but my wife's sms commands display as normal message and nothing happens...
clarify i just send "xxxx LOCK" where "xxxx" is my pin?
Also, any way to keep avast mobile security on all the time? Should Anti theft work even if i close the mobile security app? cos it doesnt on my phone...seems like a simple restart of the phone renders anti theft pointless as it doesnt even react to web commands....
