What is the best way to go about determining what kind of touchscreen a cellphone has (e.g., resistive or capacitive) and whether a pointing or stylus device can be used with it?
If you can use your fingernail to navigate on the touchscreen, then that is a resistive one. If you can't, then that is capacitive. You can use a regular stylus with resistive touchscreens, while with capacitive touchscreens you would need to use a special capacitive stylus, one that generates static electricity.
