+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!**
+

+
+## ❓ 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**
