Frequently asked questions

Yes. Create a device group, start mirroring, and enable Group Control on the first phone in the group. Your touch gestures and key mapping input on that host are forwarded to the other phones. You can stop synchronization with the same flag button.

Yes. Non-host phones still accept direct input, so you can handle an individual prompt or inspect a result. Stop Group Control before changing the host's screen if you do not want that input sent to the rest of the group.

Check it with your actual phones. Use the same app screen and orientation, then try one simple action. Different aspect ratios, font sizes, or app layouts can place controls differently; matching coordinates alone does not guarantee the same result.

Practical capacity depends on the computer, USB connections or network, video resolution, frame rate, and the work running on each device. Start with a small group and add devices while checking responsiveness.

Yes. The group toolbar includes APK installation, file upload, and Group Screenshot. Check the group membership before running a batch action. It also supports group macros, AutoJS, and ADB operations.

Yes. Assign a key mapping profile to the group and check it against each game's touch layout. Group Control forwards the host's mapped input; the game continues running on each Android phone or emulator.

You can reuse a saved Flow Profile across supported Android targets. First check the task on one device, then review app state, screen layout, assets, and inputs on each additional target. A flow that works on one screen is not automatically verified on every phone.

No. LaiCai Screen Mirroring shows and controls a connected Android phone from your computer, and the phone's apps and data stay on the phone. It can also connect supported emulator instances, but it does not create an emulator itself.

Yes. LaiCai Screen Mirroring runs on Windows and macOS, and works with real Android phones and supported emulator connections. Connect and check each device before adding it to a group.

No. LaiCai Screen Mirroring connects through USB debugging, which you turn on in Developer options and approve on the phone. Root access is not required.

Install LaiCai Screen Mirroring, turn on USB debugging on the phone, connect a data-capable USB cable, and approve the computer on the phone. Select the device to open its screen, then check that a tap, Back, and text input reach the phone before you start.

Mirroring displays the phone screen. Control also sends mouse or keyboard input back to the phone. LaiCai supports both; check input separately if your task requires it.

LaiCai includes screen recording and supports Wi-Fi connection workflows described in the connection guide. Verify the app you want to capture and test your actual network before a demo. Results depend on the device, app, and connection.

Phone and computer performance, the app or game you run, resolution, frame rate, bitrate, the USB cable, and Wi-Fi conditions all affect the result.

Unlock the phone and look for the USB debugging authorization prompt. Confirm USB debugging is on, then try a data-capable cable and another USB port. Charging alone does not mean the computer has a data connection.

Check whether the problem affects the whole phone or only one app. Verify the phone's authorization and any device-specific input settings, such as the extra USB debugging switch on Xiaomi phones. Adding game key mapping will not repair a failed basic input path.

Some apps protect parts of their display from capture. Check whether the home screen and another ordinary app mirror correctly. If only protected content is blank, the connection itself is working. LaiCai does not bypass app capture restrictions.

Yes, by connecting a physical Android phone and mirroring its screen to the computer. With LaiCai, the game runs on the phone while the PC displays gameplay and sends configured input. You still need a working phone connection.

Mirroring uses the game installed on the connected phone; it does not move that installation to the PC. Account sign-in, cloud saves, and cross-platform progress are controlled by the game.

LaiCai key mapping lets you assign keyboard and mouse inputs to touch controls such as movement and action buttons, and you can create your own layouts. Configure the layout for the game you actually use, then test it in a practice area. A change to the in-game HUD can require remapping.

Yes. The LaiCai Community shares profiles for popular games. Download one and use it right away, then adjust the key positions to match your in-game layout.

Yes. LaiCai supports controller mapping, including sticks and gyro. Confirm the controls your game needs; not every game accepts every input arrangement.

No. The phone still runs the game, so phone load and temperature matter. The connection and mirroring settings also affect what you see on the computer. There is no universal latency or frame-rate guarantee.

No universal compatibility or game-policy guarantee is possible. Check the game's rules for external controls and automation, and verify the workflow before relying on it. Displaying a game, controlling it, and automating actions are separate capabilities.

LaiCai Flow is an Android automation feature inside LaiCai Screen Mirroring. Build a saved workflow by connecting visual nodes for actions, screen checks, conditions, and task data. It supports AI-assisted setup and optional AI models inside a running workflow.

No. You can create flows by dragging and connecting nodes without writing code. AI Planner and MCP can help configure a draft, while runtime AI nodes are a separate choice. Basic actions and template matching do not need an LLM; OCR, detection, or LLM steps need their corresponding engine or model configured.

Yes. Use a saved image for template matching, OCR to read a screen region, or Android UI elements when the app exposes them. For object detection, configure a supported local YOLO/ONNX model. Check the result on your actual app before connecting it to a tap.

Yes. Text analysis can use OCR, API, file, or earlier step results. A vision-capable model can analyze a captured screen image and return structured data for a later decision. Configure the model and inspect its output before relying on it.

Flows can tap, swipe, long-press, drag, type text, send keys, use the clipboard, open or stop apps, and go Home or Back. Combine these with waits, conditions, loops, and reusable child flows. HTTP requests, ADB commands, AutoJS scripts, saved macros, files, and stored data can also be part of a workflow.

Yes. The speech action uses the local speech engine on the computer running LaiCai. It can read a reminder or a result aloud there; it does not make the Android phone speak.

For LaiCai Flow, yes: it runs its logic and image analysis on the computer and sends actions to the connected phone. For compatible workflows that need to run on the phone by itself, use LaiCai Flow Inside with LaiCai Android Agent. Network-dependent steps still require network access.

They use the same Flow Profile. LaiCai Flow runs on the computer: it reads the mirrored screen and sends taps, text, and swipes to the connected phone. Flow Inside deploys a compatible profile, with its models and assets, to LaiCai Android Agent, so recognition, conditions, and actions run on the phone without a computer or cable.

No. Flow Inside deploys only nodes marked as Android-compatible. Screen capture, accessibility, network, or storage features also need the matching permissions on the phone.

No. The controlling device only needs a browser signed in to your LaiCai account. Only the computer you control needs LaiCai Screen Mirroring.

The computer you control needs active Premium. If it does not have Premium when you turn on remote control, the purchase window opens.

Only devices signed in to the same LaiCai account can see and control your computer. To block connections, switch off “Allow remote control from other devices” on the computer.

Make sure the computer is on and online, LaiCai Screen Mirroring is running, and “Allow remote control from other devices” is on. On a Mac, also grant Screen Recording and Accessibility.

No. The browser on another phone, a tablet, or a computer signed in to the same LaiCai account is enough.

No. The phone uses the Premium of the computer it is linked to, and every phone linked to that computer can be controlled.

No. Both only need an internet connection. A few networks block direct connections, and the page tells you when it cannot connect.

Yes, with a share code. They just open the link you send or enter the code; no sign-up needed.
