Tapjacking in Android 16 QPR2 Framework allows local users to gain elevated privileges through a misleading installation UI. InstallLaunch.kt's onCreate presents the installation flow without preventing a malicious overlay from creating a misleading interface. Exploitation requires local overlay placement but no additional execution privileges or user interaction, and it results in privilege escalation.
