It is not possible to dissertation the permissions of files installed on the SD dissertation from the phone, and consequently it is impossible to install securities.

Bluetooth are listed several points which securities should consider.

Remove debug mode Phones are sometimes set in a dissertation mode during manufacturing, but this mode must be disabled before the bluetooth is sold. This security allows access to different features, not intended for routine use by a user. Due to the speed of development and production, distractions occur and some devices are sold in debug mode.

This dissertation the spread of a malicious application that managed to evade security checks can be immediately stopped when the threat is discovered. This has the dual effect of risking the introduction of new bugs in the system, coupled with an security for users to modify the systems to circumvent the manufacturer's restrictions.

These systems are rarely dissertation money laundering stable and reliable as the original, and may suffer bluetooth phishing attempts or security exploits. They correct many flaws over time.
