determine Android O/S version
The touch path varies from one device to another. Here are some common touch paths (menu layers you navigate through) to find your device Android OS version.
- Menu -> Settings -> About Phone -> Android Version
- Menu -> Settings -> About Phone -> Software Information
find WiFi MAC address
On an Android phone with Android version 2.3.3
- Menu -> Settings -> About Phone -> Status -> Wi-Fi MAC address
find WiFi IP Address
On an Android phone with Android version 2.3.3 that is already connected to Wifi and obtained an IP address. Allow time for a fresh connection to obtain an IP address and establish data communication.
- Menu -> Settings -> Wi-Fi settings, and look for the network connected to under Wi-Fi networks. Tap on the network you are connected to so that a dialog with network status, speed, signal strength, security type and IP address appears. If you have obtained a valid IP address or have one configured static it will appear here. Do not click on the Wi-Fi, "connected to..." at the top with the checkbox or you will drop the link.
configure a static IP address for WiFi
The touch path varies from one device to another. Here are some common touch paths
- Menu -> Settings -> Wi-Fi settings -> select the Network (hold down) -> Modify network config -> Show advanced options > IP settings -> Static
- Menu -> Settings -> Wireless & Networks -> Wifi Settings -> look for the network connected to under Wi-Fi networks and long press the network. -> Modify network
enable USB debugging
The USB debugging feature is sometimes needed to do things such as connect via USB cable to a PC for the purpose of basic file transfer, so that the Android device appears as a simple drive letter on the Windows machine. USB Debugging Mode was actually designed to facilitate a connection between an Android device and a computer with Android Software Development Kit (SDK). USB Debugging Mode is used to establish a direct connection between an Android device and a PC. USB Debugging is also necessary to root the Android device.
On an Android phone with Android version 2.3.3
- Menu -> Settings -> Applications -> Development -> USB Debugging
modify the WEP/WPA or other secure WiFi password for a saved network
On an Android phone with Android version 2.3.3
- Menu -> Settings -> Wi-Fi settings -> look for the network connected to under Wi-Fi networks and long press the network. -> Modify network.
turn off carrier network radio and disconnect from the carrier network while still using Wifi
With traditional Blackberry phones it was easy to turn off the radio for the telephone carrier and still use WiFi. Android phones don't seem to have a checkbox to turn on or off the telephone network radio. One way to accomplish this on many Android phones such as the Casio Commando is to use "Airplane Mode." In Airplane Mode all internal radios are deactivated, including the carrier radio, WiFi, and Bluetooth. However, you can manually turn the WiFi radio on in Airplane mode while keeping the carrier radio off.
- Turn on Airplane Mode, Menu -> Settings -> Wireless and Networks, -> check the box for Airplane mode, wait a few seconds, then check the box for Wi-Fi. The phone will be disconnected from the carrier network and can still connect to a wireless access point.
take a screenshot
Functionality depends on the Android device and Android OS version. Here are some common methods.
For old Android devices using Android OS 2.3 and older a 3rd party app is required. It may be necessary to root the device to enable functionality for the app. Some manufacturer specific models have a built in screenshot function specific to their brand. If your device is newer running Android 4 and above you can press the Volume Down and Power buttons at the same time, hold them for a second, and your phone will take a screenshot.
One some Samsung Galaxy phones you press the Power and Home buttons at the same time to take a screenshot. Some models require you to create a new screen swipe gesture.
Another method on some Android models uses only the power button. Just press and hold the power button from 1-2 seconds until you see a menu with options "Power off, Airplane mode, and Take screenshot."
