====== Special app permissions with Android 13 ======

Android 13 enforces more constraints on the apps than the previous versions. Here are some examples found on the Android 13 of a BlackView smartphone. The BlackView ROM is based on the Android AOSP, with several BlackView apps added.


===== Restricted setting =====

In some circumstance you may get the following error when trying to give some permissions to an app:

<code>
Restricted Setting
For your security, this setting is currently unavailable.
</code>

This may include e.g. the **notifications** or the **accessibility** permission.

To remove such restriction do the following:

  * **Settings** => **Apps & Notifications**, search the app and tap it.
  * Tap on **three dots**.
  * Choose "Allow restricted settings".

===== Device admin apps and external storage =====

Some apps require the **device admin** permission to perform some actions. Some of these actions are the **factory reset**, **screen lock**, etc. If an app is installed into the **external storage** (SD card), you can see the following warning into the **logcat**, when it tries to get such a permission:

<code>
W DeviceAdminAdd: Exception trying to activate admin
  ComponentInfo{de.nulide.findmydevice/de.nulide.findmydevice.receiver.DeviceAdminReceiver}
W DeviceAdminAdd: java.lang.IllegalArgumentException:
  Only apps in internal storage can be active admin:
  ComponentInfo{de.nulide.findmydevice/de.nulide.findmydevice.receiver.DeviceAdminReceiver}
</code>

If an app is installed into the external storage it will not be displayed into //Settings// => //Apps & notifications// => //Special app access// => //Device admin apps//. To move the app into the internal storage (device memory) you can go through //Settings// => //Storage// => //SD card// => //Apps//. Then tap on the app and verify the **Storage used**, eventually tap the **CHANGE** button.
