## 6. Misleading permissions approach

F-Droid shows a list of the [low-level permissions](https://developer.android.com/reference/android/Manifest.permission) for each app: these low-level permissions are usually grouped in the standard high-level permissions (Location, Microphone, Camera, etc.) and special toggles (nearby Wi-Fi networks, Bluetooth devices, etc.) that are explicitly based on a type of sensitive data. While showing a list of low-level permissions could be useful information for a developer, it's often a **misleading** and inaccurate approach for the end-user. Apps have to [request the standard permissions at runtime](https://developer.android.com/guide/topics/permissions/overview#runtime) and do not get them simply by being installed, so knowing all the "under the hood" permissions is not useful and makes the permission model unnecessarily confusing.

For example, the low-level permission `RECEIVE_BOOT_COMPLETED` is referred to in F-Droid as the *run at startup* description, when in fact this permission is not needed to start at boot and just refers to a specific time broadcasted by the system once it finishes booting, and is not about background usage (though power usage may be a valid concern).

To be fair, these short summaries used to be provided by the Android documentation years ago, but the permission model has drastically evolved since then and most of them aren't accurate anymore.

> *Allows the app to have itself started as soon as the system has finished booting. This can make it take longer to start the phone and allow the app to slow down the overall phone by always running.*

In modern Android, the background restriction toggle is what really provides the ability for apps to run in the background. Some low-level permissions don't even have a security/privacy impact and shouldn't be misinterpreted as having one. Anyhow, you can be sure that each dangerous low-level permission has a **high-level representation** that is **disabled by default** and needs to be **granted dynamically** to the app (by a toggle or user consent in general).

Another example would be the `QUERY_ALL_PACKAGES` low-level permission, which is referred to as the *query all packages* permission that "allows an app to see all installed packages". While this is somewhat correct, this can also be misleading: apps do not need `QUERY_ALL_PACKAGES` to list other apps within the same user profile. Even without this permission, some apps are visible automatically (visibility is restricted by default [since Android 11](https://developer.android.com/training/package-visibility)). If an app needs more visibility, it will declare a `<queries>` element in its manifest file: in other words, `QUERY_ALL_PACKAGES` is only one way to achieve visibility. Again, this goes to show low-level manifest permissions are not intended to be interpreted as high-level permissions the user should fully comprehend.

Play Store for instance conveys the permissions in a way less misleading way: the main low-level permissions are first grouped in their high-level user-facing toggles, and the rest is shown under "Other". This permission list can only be accessed by taping "About this app" then "App permissions - See more" at the bottom of the page. Play Store will tell the app may request access to the following permissions: this kind of wording is more important than it seems. *Update: since July 2022, Play Store doesn't offer a way to display low-level permissions anymore.*
