Google Play Protect Service (GPPS) is an Android system application that serves as a detection mechanism that protects Android devices from malware, such as phishing malware.
GPPS shares the same user control as Google Play Protect (GPP). Whenever GPP is enabled, GPPS will also turn on or off accordingly. This makes it not possible to disable GPPS if GPP is enabled.
Note: The app is currently a GMS optional feature, with plans to extend its availability to other OEMs.
Phishing Detection
Phishing Detection is one of the features of GPPS that detects phishing malware. It aims to prevent any potential theft of personal credentials and other sensitive information.
