What's a good Android app for bypassing Google account locks on used or reset devices?

Test DPC is an Android application primarily designed for testing device policy controllers, but it has found a niche in helping users bypass Google account locks, such as Factory Reset Protection (FRP). This makes it particularly useful for individuals who purchase second-hand devices or encounter locks after a factory reset. The app allows users to set up a simulated device policy environment, which can override authentication prompts and temporary admin permissions. For example, in real-world scenarios, if someone acquires a phone still linked to a previous owner's account, Test DPC can create a managed profile to skip verification steps. Specific features include the ability to configure custom DPC settings, disable system apps temporarily, and provide a sandbox for testing without a full mobile device management solution. However, users should be aware that this usage may violate Google's terms of service, and legal ownership of the device is essential. Reviews indicate that many have successfully unlocked phones with Test DPC, though some report compatibility issues with newer Android versions or specific brands. The app requires technical know-how, such as enabling USB debugging or navigating recovery modes, which can be a hurdle for casual users. Despite these limitations, for those comfortable with Android systems, it offers a practical workaround. It's also handy for developers testing enterprise configurations, adding to its versatility beyond just unlocking devices.
