But when the update started to roll out, a new issue has popped up. Google Play Protect has started to warn users to install a “harmful app” called “FactoryMode.”
Google Play Protect Warns OnePlus 3/3T users to uninstall FactoryMode
FactoryMode is the app used to be called EngineerMode. It is used during manufacturing of device. It is generally used in testing of phones before they leave the manufacturing line. It can be removed with Google Play Protect, but if support staff need to use it in the future you might have issues then.
However, Google Play Protect has determined that there is still some code within the FactoryMode app that is harmful to security. Google Play Protect works by scanning the apps code and looking for fingerprints that match a known collection of harmful code.
Security researchers have highlighted that if the attackers got access to your phone they might easily mess around with your phone. The OnePlus company said that there will be no danger to your device if you choose to remove it.
