+# AppBar Status Bar Overlap Fix Test
+
+## Test Case: Verify AppBar Padding Uses Actual Status Bar Height
+
+### Before Fix
+- Hardcoded `paddingTop = isAppbarExpanted ? 0 : 36;`
+- Fixed 36dp value doesn't account for different devices/Android versions
+- Issue occurs on newer devices like iQOO 13 with OriginOS 5 Android 15
+
+### After Fix
+- Dynamic `paddingTop = isAppbarExpanted ? 0 : Utils.getStatusBarHeight();`
+- Uses actual status bar height from system resources
+- Should work correctly across all device types and Android versions
+
+### Test Steps
+1. Launch the app on a device with different status bar height than 36dp
+2. Scroll down to collapse the AppBar
+3. Verify that the SlidingTabLayout has proper top padding
+4. Verify that the app title bar doesn't overlap with the system status bar
+
+### Expected Results
+- The SlidingTabLayout should have padding equal to the actual status bar height when AppBar is collapsed
+- No visual overlap between app title bar and system status bar
+- Proper spacing maintained across different devices and Android versions
+
+### Technical Verification
+- `Utils.getStatusBarHeight()` returns the correct status bar height in pixels
+- The method already handles fallback to 24dp for devices without proper resource identifiers
+- The fix maintains backward compatibility while solving the overlap issue
