Application Settings

Application Settings lets you customize language, visual theme, file save paths, and local display adjustments. Changes take effect after clicking Save.

Language & Theme

Choose your preferred interface language and color theme.

01

Change Language

  1. Open Application Settings from the menu bar.
  2. Click the Language dropdown and select a language.
  3. Click Save — the interface will reload in the new language immediately.
💡 LaiCai supports 9 languages: Simplified Chinese, Traditional Chinese, English, Japanese, Korean, Thai, Vietnamese, Russian, and Turkish.
02

Change Theme

  1. In the same settings window, click the Theme dropdown.
  2. Choose from: Graphite Blue, Classic Green, Warm Amber, Rosy Smoke, or Cherry Plum.
  3. Click Save to apply.

File Save Paths

Configure where LaiCai stores recordings, screenshots, and configuration files.

03

Set Save Paths

Each path can be typed directly or chosen with the Browse button. The following paths are configurable:

Video save path
Folder where screen recordings are saved.
Screenshot save path
Folder where screenshots are saved.
KeyMapping save path
Folder where key mapping profiles are stored.
AutoJS save path
Folder where AutoJS scripts are read from.
Common Phrase save path
Folder where quick-reply phrase files are stored.
Device Nickname save path
Folder where device nickname files are stored.
Device Group save path
Folder where device group configuration files are stored.

Display Tuning

Fine-tune the mirrored display appearance on your computer screen.

04

Adjust Brightness & Saturation

  1. Scroll to the Display Tuning section.
  2. Drag the Brightness slider (range −0.25 to +0.25) to brighten or darken the mirrored image.
  3. Drag the Saturation slider (range 0.0 to 2.0) to adjust color saturation.
  4. Click Save to apply.
💡 These adjustments only affect the local mirrored display and do not change anything on the phone itself.

Tips

  • Settings are applied globally to all connected devices — per-device display settings are not supported.
  • If a save path folder is deleted or moved, LaiCai will fall back to the default path automatically.
  • Changing the language requires a Save; the interface reloads immediately without restarting the app.
