This code example shows how to access device information from the system. For example to get IMEI, IMSI, Manufacturer name, Model name, Product name, Battery level, Device lock information, Battery status, Current power state, SIM status, Current profile and Supported input methods of device. Code example use QSystemDeviceInfo API from QtMobility APIs.
This article needs to be updated: If you found this article useful, please fix the problems below then delete the {{ArticleNeedsUpdate}} template from the article to remove this warning.

The article explains the supported generic Qt Mobility API, but provides example/code snippets using deprecated QWidget UI. This example should be updated to not use QWidget.
