Android 4.0 ICS brings new features and optimisations but many of them are not visible on the interface. Native screenshot feature is among one of them that allows you take a snapshot of your mobile screen.
Tking a screenshot on your ICS device is as simple as 1.2.3. No Rooting is required if you have official ICS update running on your device.
Follow these three steps to take a s creenshot of any screen on your device such as online payment proofs etc.
Locate the volume down button on your device.
Locate the power button.
Press and hold the volume down button and power button together for a second or two.
A screenshot will be taken and you will be notified with a screenshot sound. As in Gingerbread os, the sreenshots are saved in a separate folder under ‘screenshots’ in the gallery.
