Permission: com.google.android.gms.permission.PHENOTYPE_UPDATE_BROADCAST [android:exported=true]
A Broadcast Receiver is found to be shared with other apps on the device therefore leaving it accessible to any other application on the device. It is protected by a permission which is not defined in the analysed application. As a result, the protection level of the permission should be checked where it is defined. If it is set to normal or dangerous, a malicious application can request and obtain the permission and interact with the component. If it is set to signature, only applications signed with the same certificate can obtain the permission.
High Broadcast Receiver (com.google.android.libraries.phenotype.client.stable.AccountRemovedBroadcastReceiver) is not Protected. [android:exported=true]
A Broadcast Receiver is found to be shared with other apps on the device therefore leaving it accessible to any other application on the device.

Low android.permission.QUERY_ALL_PACKAGES Allows query of any normal app on the device, regardless of manifest declarations.
Low android.permission.ACCESS_WIFI_STATE view Wi-Fi status
Allows an application to view the information about the status of Wi-Fi.
Low android.permission.RECEIVE_BOOT_COMPLETED automatically start at boot
Allows an application to start itself as soon as the system has finished booting. This can make it take longer to start the phone and allow the application to slow down the overall phone by always running.
Low android.permission.INTERNET full Internet access
Allows an application to create network sockets.
Low android.permission.ACCESS_NETWORK_STATE view network status
Allows an application to view the status of all networks.
Medium com.google.android.providers.gsf.permission.WRITE_GSERVICES modify the Google services map
Allows an application to modify the Google services map. Not for use by common applications.
Medium android.permission.CHANGE_COMPONENT_ENABLED_STATE enable or disable application components
Allows an application to change whether or not a component of another application is enabled. Malicious applications can use this to disable important phone capabilities. It is important to be careful with permission, as it is possible to bring application components into an unusable, inconsistent or unstable state.
Medium android.permission.CHANGE_CONFIGURATION change your UI settings
Allows an application to change the current configuration, such as the locale or overall font size.
