I don't understand how to navigate the android device. I don't understand how to swipe, and how to tap. I found out from the dictionary that swiping means a hard hit, and that can't be done with the device: again, I don't know how to tap. When I tap I don't get any activation of what I touch. Sometines, when i touch the screen from up to down, I keep hearing the same item being spoken. So my problem now is that since I can't use the touch screen, can my bluetooth keyborde serve as a useful alternative. I discoveered that I cannot navigate some apps with the bluetooth keyboard. Please what can I do. Can you give me tips on how to swipe and tap?
