It is unlikely for whatsapp to need root privileges, and impossible for zygote to ask for them. zygote is an essential system component that is started by /init process itself, so it does implicitly inherit root privileges. matter fact, zygote is responsible for starting every other app, being it system app or not.

Having said that, these two apps are strongly malware. if you have adb, issue 'adb shell ps | grep zygote', I believe the output will be two apps: one is the real zygote, and the other 'zygote' is part of a package name.

Zygote is an essential system component that is started by init process itself while booting, so it does implicitly inherit root privileges.
Matter of fact, zygote is responsible for starting every other app, be it system apps or other apps.

Having said that, these two apps (installed in your device that asks for root access) are strongly MALWARE.

If you have ADB, issue the command adb shell ps | grep zygote. (Or from Terminal Emulator as ps | grep zygote)
