If you hear a screaming phone you may be in the presence of stolen property. A remotely activated female scream is one of the features of the Mobile Manager software from Synchronica. The feature was designed to make the phone useless in the hands of thieves. Once activated, the scream can be only deactivated by reflashing of the internal memory or by removing the battery or shutting off the phone.

The software also allows users to remotely lock or delete sensitive data.
