Ever joined your team in PUBG Mobile KR 4.1 and found that your mic isn’t working? It’s really annoying — you’re trying to talk or share callouts, but your teammates can’t hear you at all.
Don’t worry! This simple guide will help you fix the mic issue in PUBG Mobile KR 4.1. Everything is explained in easy English, so anyone can follow it.
By the end of this guide, you’ll know how to make your mic work again, step by step — whether you play on Android or iPhone.
Understanding the Mic Glitch in the KR 4.1 Update
What is the KR 4.1 Update?
The KR (Korean) version of PUBG Mobile is slightly different from the global version. It often gets new features and patches first, which sometimes means more bugs sneak through early.
The 4.1 update brought exciting changes — new graphics, better weapon balance, and upgraded modes — but along with that came some unexpected mic issues.
What Mic Problems Are Users Experiencing?
Players across Reddit, Discord, and community forums have reported issues like:
- Mic not working at all in the game.
- Mic turning on but teammates can’t hear your voice.
- Mic working in the lobby but not during the match.
- Headset audio working fine but the microphone not detecting input.
Why This Glitch Matters (Especially in Team Play)
PUBG is all about teamwork. When your mic fails mid-match, it’s like trying to play chess without seeing your opponent’s moves. Communication keeps your team alive — and without it, even the best reflexes can’t save you.
Pre-Check: Before You Dive Into Fixes
Before we jump into advanced fixes, let’s get the basics out of the way. Sometimes, it’s the simplest things that cause the biggest problems.
Check Microphone Permissions on Your Device
Make sure PUBG Mobile KR has permission to use your mic.
For Android:
- Go to Settings → Apps → PUBG Mobile KR → Permissions
- Tap Microphone → Allow
For iPhone (iOS):
- Open Settings → Privacy → Microphone
- Make sure the toggle for PUBG Mobile KR is turned ON
Confirm In-Game Audio and Mic Settings
- Open PUBG Mobile KR.
- Go to Settings → Audio.
- Ensure Voice Chat is ON.
- Check that Microphone and Speaker volume levels are set high enough.
- Choose the correct chat mode — Team or All — depending on what you want.
Restart the Game and Clear Cache
Before anything else, try a simple restart. Then clear your game cache:
- On Android: Settings → Apps → PUBG Mobile KR → Storage → Clear Cache
- On iOS: Restart your device and reopen the game.
This often clears temporary bugs from updates.
Step-By-Step Fixes for the Mic Glitch
Fix 1: Toggle In-Game Voice Chat Settings
Sometimes the settings just need a refresh.
How to Navigate to Voice Chat Settings in KR Version
- Open PUBG Mobile KR.
- Tap the Gear icon (Settings) → Audio.
- Turn Voice Chat OFF.
- Exit the menu, then go back and turn it ON again.
What to Change (Enable/Disable, Select Correct Mic)
- Set Voice Channel to Team (not All).
- Choose Open Mic if you don’t want to press a button every time you speak.
- If using a headset, switch between Default and External Mic options.
Fix 2: Clear Game Cache and Repair Game Files
Clearing Cache on Android
- Exit the game.
- Go to your phone settings → Apps → PUBG Mobile KR → Storage.
- Tap Clear Cache (not Clear Data).
Repairing Game Files via Launcher
- On the PUBG Mobile KR login screen, tap Repair at the bottom corner.
- Choose Routine Repair and confirm.
- The app will download missing or corrupted files automatically.
This often fixes missing mic configuration files that cause the glitch.
Fix 3: Reinstall the Game or Update to the Latest Patch
Why Reinstalling Helps
Sometimes, when the update installs, some files don’t download properly. A fresh install ensures everything is clean.
How to Install Updates in the KR Region
- Back up your PUBG account (Facebook, Google, or Twitter login).
- Uninstall PUBG Mobile KR.
- Visit the official KR store or Galaxy Store and download the latest version (4.1.x or newer).
- Log in again and test your mic in the lobby.
Fix 4: Check Device-Level Mic Settings and Other Apps
Ensure No Other App Is Using Microphone
Close apps like Discord, Zoom, or Messenger that might be using your mic in the background.
You can check this by:
- Going to Settings → Privacy → Microphone and seeing which apps used it recently.
Disable Battery-Saving/Optimization Affecting Mic
Some devices (like Xiaomi, Vivo, and Samsung) limit microphone access to save battery.
Go to Battery Settings → App Optimization → PUBG Mobile KR → Don’t Optimize.
Fix 5: Use a Compatible External Mic or Headset
Why Headsets Sometimes Cause Mic Issues
Certain headphones (especially Bluetooth ones) can confuse the system between audio output and mic input, making PUBG pick the wrong one.
How to Switch Between Internal and External Mic
- Open Settings → Audio inside PUBG.
- Look for Mic Source.
- Switch between Built-in Mic and External Mic.
- Speak in the lobby to test.
If your teammates can hear you now, problem solved!
Special Considerations for the KR Server Version
Differences Between KR and Global Version
The Korean version runs on different servers and sometimes uses unique file paths. That means fixes for the global version don’t always apply to KR.
Language Barrier and Support Options
If menus are in Korean:
- Look for the microphone icon instead of reading text.
- You can also use Google Lens to translate the text on your screen.
- For official help, contact PUBG Mobile KR support via in-game Help → Report a Problem.
How to Switch to Global Server if KR Version Persists Issues
If your mic still doesn’t work:
- Uninstall PUBG Mobile KR.
- Install PUBG Mobile Global from Play Store.
- Log in with the same account (if supported).
This ensures you’re on servers with faster bug patches.
Preventing Future Mic Glitches
Keep Your Game and Device Updated
Always stay on the latest PUBG Mobile KR and Android/iOS version. Updates often contain mic-related fixes and performance improvements.
Avoid Installing Modded Versions or APKs
Unofficial or modded versions can cause security risks and mess with microphone permissions.
Stick to official stores like Google Play or Galaxy Store.
Regularly Check Voice Chat Settings After Major Updates
Every time PUBG releases a big update, the settings sometimes reset. So before you join a ranked match:
- Go to Settings → Audio.
- Make sure Voice Chat is still enabled.
- Test your mic in the lobby with your friends.
Conclusion
The mic glitch problem in PUBG Mobile KR 4.1 might feel annoying, but it’s usually easy to fix once you know where to look. Start with checking permissions and in-game settings. Then move to clearing cache, repairing files, or reinstalling if necessary. Within minutes, you’ll be back giving those clutch callouts that win matches.
