Using a mouse
One thing many new iPhone users don’t know about their smartphones is that they come equipped with wired and Bluetooth device support. So, if you prefer using a smartphone like a miniature laptop, you can always connect a mouse to your iPhone. Setting it up is easy and takes just a few seconds.
To enable your mouse, open Settings, Accessibility, and then tap Touch. Connect your mouse to the phone and bind the mouse clicks to specific needs. For instance, some people bound their mouse’s side button to call on Siri for help. Using a mouse will totally help you win in online FPS games.
