High Broadcast Receiver (.UnifiedBroadcastReceiver) is not Protected.An intent-filter exists.
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. The presence of intent-filter indicates that the Broadcast Receiver is explicitly exported.
Low Service (.UnifiedSettingService) is Protected by a permission, but the protection level of the permission should be checked.
Permission: com.verizon.settings.permission.RECEIVE_UPDATED_SETTING
protectionLevel: signatureOrSystem [android:exported=true]
A Service is found to be exported, but is protected by a permission. However, the protection level of the permission is set to signatureOrSystem. It is recommended that signature level is used instead. Signature level should suffice for most purposes, and does not depend on where the applications are installed on the device.
