Many PUBG Mobile players want the precision of a desktop setup: WASD movement, mouse aim, left-click fire, right-click scope, and fast access to jump, crouch, prone, reload, backpack, map, and throwables. The problem is simple: PUBG Mobile is designed for touch screens, while most PC players are used to keyboard and mouse control.
With LaiCai Screen Mirroring, you can keep PUBG Mobile running on your real Android phone, mirror the screen to your computer, and build a fully custom keyboard and mouse layout on top of the mobile controls. You are not forced into a fixed template. Every key can be configured around your own play style.
Why Use a Real Android Phone Instead of Only an Emulator?
Some players use Android emulators, Bluetooth keyboards, mobile adapters, or gaming phone tools. Each method has tradeoffs around performance, compatibility, input behavior, and account safety. LaiCai takes a different approach: the game still runs on your Android phone, while your computer becomes the larger screen and control station.
The workflow is straightforward: run PUBG Mobile on your Android phone, connect the phone to LaiCai on your PC or Mac, mirror the screen, add keyboard and mouse mappings, then tune the layout until it feels natural.
What You Need Before Starting
You need an Android phone with PUBG Mobile installed, a Windows or macOS computer with LaiCai installed, a USB data cable for the first connection, USB debugging enabled on Android, and a keyboard and mouse connected to your computer.
For the smoothest experience, start with a wired USB connection. PUBG Mobile is a fast shooting game, so lower latency matters. Once everything is working, you can test WiFi mode and decide whether it is stable enough for your setup.
Step 1: Connect Your Android Phone to LaiCai
Open LaiCai on your computer and connect your Android phone with a USB data cable. If this is your first time connecting the phone, enable Developer Options and USB debugging on Android, then allow the computer when the phone asks for USB debugging permission.
After the phone appears in LaiCai, add it to your device list and open the mirrored screen. Launch PUBG Mobile on the phone and enter the lobby or training ground before building your mapping layout.
Step 2: Choose a Stable In-Game Layout
Before mapping keyboard and mouse controls, set up your PUBG Mobile touch layout. LaiCai maps desktop input to touch buttons on your phone screen, so your in-game button positions should be stable and easy to target.
Place fire, aim, jump, crouch, prone, reload, weapon slots, backpack, map, and throwables in clear positions. You do not need to copy another player's layout. The advantage of LaiCai is that you can build your own control system from scratch.
Step 3: Create a Custom Keyboard Mapping Profile
In LaiCai, open the key mapping tool and create a new profile for PUBG Mobile. Place mappings directly onto the mirrored phone screen. Each mapping connects a keyboard key, mouse button, or mouse movement behavior to a touch action in the game.
A practical starting layout is: W/A/S/D for movement, left mouse button for fire, right mouse button for scope, Space for jump, C for crouch, Z for prone, R for reload, F for interact, Tab for backpack, M for map, 1 and 2 for weapons, G for throwables, and Q/E for leaning.
This is only a starting point. LaiCai does not lock you into these keys. If you prefer another shooter layout, a left-handed layout, a compact laptop layout, or a mouse-button-heavy layout, you can adjust every part of it.
Step 4: Configure Mouse Aim and Camera Movement
Mouse control is the most important part of playing PUBG Mobile from a computer. Configure the mouse movement area so moving your mouse controls the camera view in PUBG Mobile. Test slowly and quickly in the training ground, then adjust both LaiCai mapping settings and PUBG Mobile sensitivity.
A good setup should let you turn naturally, track moving targets, control recoil, and switch between hip-fire and scoped aiming without fighting the controls. Tune one setting at a time.
Step 5: Map Touch, Swipe, Drag, and Multi-Touch Actions
PUBG Mobile is not just about tapping buttons. Some actions depend on swipes, drags, camera movement, joystick movement, and multiple touch points. LaiCai supports flexible mapping types so you can turn mobile gestures into desktop-friendly controls.
You can map a key to a single touch point for reload, map a mouse button to fire, map mouse movement to camera drag, or create multi-touch mappings for actions that need more than one point. The best PUBG Mobile keyboard layout is personal, and LaiCai makes it fully customizable.

Tips for Better Control and Lower Latency
Use USB first, because a wired connection usually gives the most stable response for fast shooters. If you switch to WiFi, keep the phone and computer on the same local network. If input feels delayed, reduce resolution or frame rate until controls feel responsive.
After changing your mapping, enter training mode and test movement, recoil, scope switching, throwables, and vehicles. Save your PUBG Mobile profile in LaiCai once it feels right.
Important Fair-Play Reminder
Always follow PUBG Mobile's current rules, regional policies, and event requirements. Keyboard and mouse workflows, emulators, adapters, macros, and automation may be treated differently depending on game mode, region, tournament rules, or future policy changes.
Use key mapping responsibly. Do not use tools to create unfair automation, recoil scripts, cheating behavior, or anything that violates PUBG Mobile's terms. LaiCai's mapping system is best used to make control more comfortable, not to replace player skill.
Conclusion
With LaiCai Screen Mirroring, you can mirror your Android phone to a computer, control PUBG Mobile with keyboard and mouse, and customize every key mapping yourself. Start with WASD, mouse aim, left-click fire, and right-click scope, then refine movement, looting, driving, leaning, throwables, and inventory until the setup feels natural.
