Define data connection of apps (Wi-Fi/Mobile data)

For each app installed on the OnePlus smartphone, we can individually determine whether it should connect to the mobile data and or via the Wi-Fi network to the Internet.

This feature gives us more control over the data volume, since streaming apps such as Netflix, YouTube & Co. can be denied access to the mobile data.

Apps to display in fullscreen

Special app access

The special app access on the OnePlus smartphone lists all special access requirements of apps, such as changing system settings or showing one app over another.

Using the special app access we can grant or withdraw the requested access to individual apps at any time.

Individual app permissions

Each app installed on the OnePlus smartphone requires permissions to access the memory or contacts, for example.

If a particular function is performed by an app, such permission is automatically requested and can be granted or denied immediately.

By denying requested permissions, some app functions can be used partially or not at all. However, it is advisable to question one or the other permission, since, for example, not every app necessarily requires access to our location.

Depending on the authorization and type of app, the required access can be defined as follows:

  • Allow
  • Allow while using the app
  • Reject

Note: A granted authorization can be revoked at any time and vice versa.

Background data usage of an app

We can decide for ourselves which installed apps on the OnePlus smartphone are allowed to access background data usage in order to have a little more control over our own data volume.

Install unknown apps

If we want to install apps outside of the Google Play Store on the OnePlus smartphone, such as .apk files, the appropriate file must be downloaded.

To do this, the browser app you are using must have permission to allow apps from an unknown source, which is a pure security measure by Android to protect against malware.

Step 2:  Tap on  Apps & notifications
Step 3:  Tap on  Special app access

Display over other apps

There are apps installed on the OnePlus smartphone that will sooner or later request permission to appear or show over other apps.

A very fitting example is the Facebook Messenger app, which displays the profile photo of the chat partner at the edge of the screen when a new message is received in a conversation or chat.

Android 10 (OxygenOS 10.0)
Step 1:  Open the  Settings
Step 2:  Tap on  Apps & notifications
