Information such as your PIN, IMEI, OS version, and even signal strength can be found by navigating through the option menus and viewing sections such as About and Status, however there is a simpler way to view most of it on one screen. Using this simple keyboard shortcut, you can display all of your basic device information in one place, directly from your home screen.
This function serves primarily as a help feature while troubleshooting with technical support, though it comes in very handy for most users who learn about it.
To access the Help Me status screen, simply hold down the ALT and CAP keys simultaneously, and press H.
You will now see all of your device’s general information, including OS version, PIN, IMEI (or ESN), signal strength, battery level, and available/total memory.
