Real-time Performance Monitoring & Logging

---

📊 What is GameBar?

GameBar is a real-time performance overlay that displays FPS, CPU/GPU usage, temperatures, RAM stats, and more while you use apps. It includes powerful logging and analytics features to record and analyze performance data.

Perfect for:

• 🎮 Gaming performance testing & optimization
• 📱 App benchmarking & comparison
• 🔥 Thermal analysis & throttling detection
• ⚡ Battery drain investigation
• 📈 Performance tracking over time

---

🚀 Quick Start Guide

Step 1: Enable GameBar Overlay

1. Open Settings app
2. Navigate to System → GameBar
3. Turn ON the "Enable GameBar Overlay" switch
4. Grant overlay permission if asked

✅ You'll see the GameBar overlay on your screen!

⚠️ IMPORTANT: The GameBar overlay MUST be ON to collect performance data. Logging cannot work when the overlay is disabled.

Step 2: Choose Your Logging Mode

GameBar offers 3 logging modes to fit your needs:

Mode	Icon	Best For	How It Works
Per-App	🎯	Specific apps/games	Auto-logs when configured apps are in foreground
Universal	🌐	All apps	Logs everything while GameBar is active
Manual	👆	Quick testing	Double-tap overlay to start/stop logging

Step 3: Configure & Start Logging

Follow the detailed guide below for your chosen mode ⬇️

---

🎯 Mode 1: Per-App Logging (Recommended)

🌟 Best for tracking specific games or apps over time

What it does:

• Automatically starts logging when you open a configured app
• Automatically stops and saves when you close the app
• Each session saved separately with timestamp
• Perfect for comparing performance across gaming sessions
• Requires GameBar overlay to be ON

How to Set Up:

⚙️ Setup (One Time)

1. Go to Settings → System → GameBar
2. Tap "Per-App GameBar"
3. Tap "Configure Apps"
4. Select your game/app from the list (e.g., BGMI, COD Mobile, Chrome)
5. Enable the switch for that app
6. Go back to GameBar main settings
7. Tap "GameBar Logging"
8. Select "Per-App Logging" mode
9. Turn ON the main "Enable GameBar Overlay" switch

📱 Using It

1. Ensure GameBar overlay is ON (critical requirement!)
2. Open your configured game/app
3. That's it! 🎉

What happens:

• ✅ Toast message: "BGMI GameBar log started"
• GameBar collects FPS, CPU, GPU, temps, etc. while you play
• Close the game → Toast: "BGMI GameBar log ended"
• Log automatically saved with timestamp!

⚠️ Important: If GameBar overlay is OFF when you open the app, you'll see: "BGMI: GameBar logging enabled but GameBar overlay is OFF. Turn ON GameBar to collect logs."

📂 Viewing Your Logs

1. Go to Settings → System → GameBar
2. Tap "Per-App GameBar"
3. Find your app → Tap it
4. See all sessions with timestamps and duration!
5. Tap any session to view detailed analytics

Log file location: /sdcard/Documents/GameBar/PerAppLogs/{package_name}/

---

👆 Mode 2: Manual Logging (Double-Tap)

⚡ Best for quick tests without setup!

What it does:

• Start/stop logging with double-tap gesture
• Works in any app (no configuration needed)
• Logs saved under that app's name in per-app logs
• Great for one-time performance checks
• Only works in Per-App Logging mode

How to Use:

📱 Taking a Manual Log

1. Go to GameBar → GameBar Logging → Select "Per-App Logging"
2. Turn ON GameBar overlay (must be ON!)
3. Open any app (doesn't need to be configured)
4. Double-tap the GameBar overlay
   • Toast: "AppName: Manual logging started"
5. Use the app normally (gaming, browsing, etc.)
6. Double-tap again to stop
   • Toast: "Manual logging stopped and saved"

⚠️ Important Notes:

• GameBar overlay must be ON to collect data
• If app already has auto-logging enabled, double-tap shows: "This app has auto-logging enabled. Logs are saved automatically."
• Manual logs and auto logs are stored in the same location
• You can manually log apps that aren't in your configured list

📂 Finding Your Logs

Same location as auto logs:

1. GameBar → "Per-App GameBar"
2. Find the app you manually logged
3. All sessions (auto + manual) appear together!

---

🌐 Mode 3: Universal Logging

📊 Best for continuous monitoring across all apps!

What it does:

• Records data from ALL apps in one continuous log
• You control start/stop with double-tap
• Good for multi-app benchmarks and system-wide monitoring
• Logs everything while active (app switches included)

How to Use:

⚙️ Setup

1. Go to GameBar → "GameBar Logging"
2. Select "Universal Logging" mode

📱 Taking a Universal Log

1. Turn ON GameBar overlay (required!)
2. Double-tap GameBar overlay to start
   • Toast: "Capture Started"
3. Use different apps, switch between them, test anything
4. Double-tap again to stop
   • Toast: "Capture Stopped and Data Exported"

📂 Finding Your Logs

1. GameBar → "GameBar Logging" → "View Logs"
2. Universal logs are stored in: /sdcard/Documents/GameBar/GameBar_log_{timestamp}.csv
3. Each log contains data from all apps used during that session

❓ Troubleshooting

❌ "GameBar logging enabled but overlay is OFF"

Problem: You enabled per-app logging, but GameBar overlay is turned off.

Why this happens:

• GameBar requires the overlay to be ON to collect performance data
• Without the overlay, there's no data source to log

Solution:

1. Go to GameBar settings
2. Turn ON "Enable GameBar Overlay" switch
3. You should see the overlay appear on screen
4. Now logging will work automatically!

❌ Double-tap doesn't start logging

Possible causes:

1. Double-tap gesture disabled

   • Go to GameBar → Overlay Gesture Controls
   • Enable "Double-tap to capture"

2. App has auto-logging enabled

   • If the app is in your per-app list, it's already logging automatically
   • You'll see: "This app has auto-logging enabled. Logs are saved automatically."
   • No need to double-tap!

3. Wrong logging mode

   • Manual double-tap only works in Per-App Logging mode
   • Check: GameBar → GameBar Logging → Select "Per-App Logging"

4. GameBar overlay is OFF

   • Logging requires overlay to be ON
   • Turn on the main GameBar switch

5. Tapping too slow

   • Tap faster (like double-tap to unlock phone)

❌ Can't find my logs

Check these locations:

For Per-App Logs:

1. In-app: GameBar → Per-App GameBar → Select your app
2. File manager: /sdcard/Documents/GameBar/PerAppLogs/{package_name}/
3. Search for: *_GameBar_log_*.csv

For Universal Logs:

1. In-app: GameBar → GameBar Logging → View Logs
2. File manager: /sdcard/Documents/GameBar/
3. Search for: GameBar_log_*.csv

❌ No data in log file (empty or only header)

Common causes:

1. GameBar overlay was OFF during session

   • Solution: Turn ON overlay before logging

2. Session too short (< 2 seconds)

   • Solution: Log for at least 5-10 seconds to collect meaningful data

3. App crashed or force closed

   • Solution: Let the app close naturally or use double-tap to stop

4. Storage permission denied

   • Solution: Grant storage permission to GameBar in Android settings

❌ Analytics won't open / Shows error

Possible causes:

1. Corrupted log file

   • Try opening a different session
   • Re-log the session

2. Log file too large

   • Very long sessions (>2 hours) may take time to analyze
   • Wait for "Analyzing..." dialog to complete

3. Missing data columns

   • Ensure you have FPS, CPU, GPU data enabled in overlay settings

❌ Export/Share not working

Solutions:

1. No file manager app

   • Install a file manager (Files by Google, etc.)

2. Storage permission denied

   • Go to Android Settings → Apps → GameBar → Permissions
   • Grant Storage permission

3. No app to open CSV

   • Install Google Sheets, Excel, or any CSV viewer

💡 Pro Tips

🎮 For Gamers

1. Enable per-app logging for your main games
2. Log a few sessions to find average performance
3. After updates, compare logs to see improvements/issues
4. Share logs with devs when reporting lag

📱 For Testers

1. Use global mode to compare apps
2. Test in identical conditions (same brightness, network, etc.)
3. Let apps run for at least 5 minutes for accurate data
4. Close background apps for cleaner results

🔥 For Thermal Testing

1. Enable all temperature sensors (CPU, GPU, Battery, RAM)
2. Run intensive tasks (gaming, video recording)
3. Watch for thermal throttling (FPS drops when temp rises)
4. Compare temperatures across different scenarios

⚡ For Battery Investigation

1. Log with GameBar overlay OFF initially
2. Then log with overlay ON
3. Compare power consumption (overlay itself uses ~1-2% battery)
4. Find which apps drain the most
