Oppo How to Adjust Security Settings

Apps that do not originate from the official Google Play Store cannot be installed on the Oppo smartphone without access rights, so the app must be explicitly allowed (for example, the file manager) to install an .apk app from an unknown source.

Apps that want to get deep functionality into the system on the Oppo-Smartphone have to be identified as device administrators (device managers). A classic example is the "Find my device" feature from Google, which is installed by default on an Android device. To remotely reset the Oppo-Smartphone to factory defaults, the app has to be a device administrator.

Device administrators can be managed under ColorOS in the security settings.

Note: Any app cannot be defined as a device manager. The app must request access itself. Only then will it be visible in the settings to activate it.

Losing your Oppo smartphone can not only result in a financial loss, but also a personal one. On most Android smartphones, the "Find My Device" feature is installed and activated at the factory, just like on Oppo smartphones with ColorOS.

Google Play Protect is a service that regularly checks apps for malicious behavior and depending on the security relevance, the app is blocked or a notification appears.

By default, Google Play Protect is enabled on the Oppo smartphone, but can be disabled in the settings.

If passwords are entered in text fields on the Oppo-Smartphone, the last character entered is shown visibly on the screen, so it is possible to read the password. If this is (not) desired, the "Show password" function can be activated or deactivated in the security settings.
