App data usage

Installing apps on the Oppo smartphone allows access to WLAN and the mobile data by default. ColorOS allows us to control apps' access to the Internet. For example, we can completely disable the Internet for an app, but we can also instruct the device to only give the app access to the mobile data or WLAN.

Background Data

In order to receive notifications from apps that are not currently actively used on Oppo smartphones, the background data of the respective app must be activated, which it is by default, allowing the app to access the Internet in the background.

If background data is deactivated, no data can be accessed via the Internet and therefore no notifications will appear (does not apply to offline notifications).

Permission to Change system settings

Autostart

After starting the Oppo smartphone, not only the operating system ColorOS (Android) is loaded, but also fixed apps, but too many apps with an "autostart" can make the device sluggish.

On the Oppo-Smartphone there is an autostart manager, with which apps can be defined quickly and easily, which are executed automatically in the background when the smartphone starts.

Step 4:  Enable or Disable desired  App

Background activity

To extend the battery life of the Oppo smartphone, Android offers a lot of optimization functions. A small but powerful function is the background activity. If it is activated, ColorOS or Android can decide for itself when the app may run in the background and when not.

This function is also responsible for the fact that most apps are closed after about two minutes when the screen is switched off. In order to allow the app to continue running, background activity must also be allowed.

In return, the app can also be denied background activity.

In order for apps like Messenger to show up on top of other apps, the "floating windows" feature must be enabled on the Oppo smartphone so that apps can show up on top of other apps and provide quick access to its features.
