To enable mouse support on your iPhone, you need to use the AssistiveTouch feature. Here's how:
- Open the Settings app on your iPhone.
- Navigate to Accessibility: Scroll down and tap on "Accessibility."
- Go to Touch: In the Accessibility settings, tap on "Touch."
- Select AssistiveTouch: Tap on "AssistiveTouch."
- Turn on AssistiveTouch: Toggle the switch next to "AssistiveTouch" to the "on" position.
Once AssistiveTouch is enabled, you can connect a compatible Bluetooth or USB mouse (or other pointer device such as a trackpad or game controller) to your iPhone. The device will then control an on-screen cursor.
Note: Your iPhone must be running a version of iOS that supports assistive pointer devices. Modern versions of iOS typically have this functionality.
