Google Details Security Enhancements in Android 4.2.2
Upgraded Android version offers enhanced security predominately for developers and root/mod users.
Following the release of Android 4.2.2, Google has detailed the security enhancements of the updated mobile operating system.
Additionally, a new option to USB debugging in Android 4.2.2 has been integrated; it allows users to lock USB debugging mode apart from when connected to a PC. Elsewhere, it offers general improvements for performance and stability for several Nexus devices (GSM Galaxy Nexus smartphone, the Nexus 7 and the Nexus 10 tablets are the devices to thus far receive the update), as well as a streaming audio issue.
The latest Android Jelly Bean upgrade comes after a study found that Google's mobile platform is increasingly becoming a growing target for malware. Android 4.2, meanwhile, introduced an updated malware scanner that checks third-party apps.
