How to Control Your Phone in LaiCai

Once your phone is mirrored, you can control it with mouse, keyboard, or a connected gamepad. This guide walks through every interaction surface in LaiCai.

🖱️

Touch & Mouse Control

The mirrored phone screen behaves like a real touchscreen. Mouse actions are translated into touch events on the phone in real time.

Left-click
Single tap on the phone screen.
Left-click & drag
Swipe / drag on the phone (great for Maps, scrolling, drawing).
Mouse wheel
Scroll the content under the cursor (lists, web pages).
Ctrl / ⌘ + drag
Two-finger pinch gesture — useful for zooming maps, photos, and pages.
⌨️

Keyboard Input

Whenever the phone screen is focused, your keyboard input is forwarded to the phone — type into apps, search bars, chat windows directly from your computer.

  • Type into any focused text field on the phone
  • Common shortcuts (copy, paste, select all) work depending on the app
  • Use the side toolbar's "Select Phrase" to paste preset texts quickly

Tips

  • If keyboard input does not reach the phone, click on the phone screen first to give it focus.
  • Use Group Control to operate many phones with a single mouse — record once, sync to many.
  • Set up a Key Mapping profile to play mobile games with WASD + mouse aim like on PC.
