Mobile Comparison Issues

Troubleshoot common mobile comparison issues and optimize your mobile experience.

Common Mobile Issues

Comparison Table Not Displaying

Symptoms: Comparison table doesn't appear on mobile devices

Causes:

• Mobile scripts not properly loaded
• CSS conflicts with theme styles
• JavaScript errors on mobile browsers
• Network connectivity issues

Solutions:

1. Check Script Loading:

   // Verify scripts are loaded
   if (typeof XBCompare === 'undefined') {
     console.error('XB Compare scripts not loaded');
   }

2. Mobile-Specific CSS:

   @media (max-width: 768px) {
     .xb-compare-table {
       display: block !important;
       width: 100%;
     }
   }

3. Clear Mobile Cache:

   • Clear browser cache on mobile device
   • Hard refresh the page (Ctrl+F5 or Cmd+Shift+R)
   • Test in incognito/private browsing mode

Touch Interaction Problems

Symptoms: Buttons don't respond to touch, scrolling issues

Causes:

• Touch targets too small
• CSS preventing touch events
• JavaScript touch event conflicts
• Browser compatibility issues

Solutions:

1. Increase Touch Target Size:

   .xb-compare-button {
     min-height: 44px;
     min-width: 44px;
     padding: 12px;
   }

2. Enable Touch Events:

   .xb-compare-table {
     touch-action: manipulation;
     -webkit-touch-callout: none;
   }

3. Fix Touch Event Handling:

   // Ensure touch events work
   document.addEventListener('touchstart', function(e) {
     e.preventDefault();
   }, { passive: false });

Layout and Display Issues

Symptoms: Table layout broken, text cut off, images not displaying

Causes:

• Responsive CSS not working
• Fixed widths causing overflow
• Image optimization issues
• Font size problems

Solutions:

1. Responsive Table Layout:

   @media (max-width: 768px) {
     .xb-compare-table {
       font-size: 14px;
       overflow-x: auto;
     }
   
     .xb-compare-table th,
     .xb-compare-table td {
       padding: 8px 4px;
       white-space: nowrap;
     }
   }

2. Image Optimization:

   .xb-compare-image {
     max-width: 100%;
     height: auto;
     object-fit: cover;
   }

3. Text Sizing:

   @media (max-width: 768px) {
     .xb-compare-text {
       font-size: 14px;
       line-height: 1.4;
     }
   }

Performance Issues

Slow Loading on Mobile

Symptoms: Comparison table takes too long to load

Causes:

• Large images not optimized
• Too many fields being loaded
• Network latency
• JavaScript execution time

Solutions:

1. Image Optimization:

   .xb-compare-image {
     width: 150px;
     height: 150px;
     object-fit: cover;
   }

2. Lazy Loading:

   // Implement lazy loading for images
   const images = document.querySelectorAll('.xb-compare-image');
   const imageObserver = new IntersectionObserver((entries) => {
     entries.forEach(entry => {
       if (entry.isIntersecting) {
         const img = entry.target;
         img.src = img.dataset.src;
         imageObserver.unobserve(img);
       }
     });
   });
   
   images.forEach(img => imageObserver.observe(img));

3. Reduce Field Count:

   • Show only essential fields on mobile
   • Load additional fields on demand
   • Use progressive enhancement

Memory Issues

Symptoms: App crashes or becomes unresponsive

Causes:

• Too many products being compared
• Large data objects in memory
• Memory leaks in JavaScript
• Browser limitations

Solutions:

1. Limit Product Count:

   const MAX_MOBILE_COMPARISONS = 3;
   
   if (window.innerWidth <= 768 && selectedProducts.length > MAX_MOBILE_COMPARISONS) {
     showAlert('Maximum 3 products can be compared on mobile');
     return;
   }

2. Memory Management:

   // Clean up event listeners
   function cleanup() {
     document.removeEventListener('touchstart', handleTouch);
     // Remove other event listeners
   }
   
   // Call cleanup when component unmounts
   window.addEventListener('beforeunload', cleanup);

Browser-Specific Issues

iOS Safari Issues

Common Problems:

• Viewport height issues
• Touch event handling
• CSS flexbox problems
• WebKit-specific bugs

Solutions:

1. Fix Viewport Height:

   .xb-compare-wrapper {
     height: 100vh;
     height: -webkit-fill-available;
   }

2. iOS Touch Fixes:

   .xb-compare-button {
     -webkit-tap-highlight-color: transparent;
     -webkit-touch-callout: none;
   }

Android Chrome Issues

Common Problems:

• Address bar hiding/showing
• Touch scrolling
• Performance on older devices
• Memory management

Solutions:

1. Address Bar Handling:

   // Handle address bar changes
   window.addEventListener('resize', () => {
     // Recalculate layout when address bar changes
     setTimeout(() => {
       window.scrollTo(0, 0);
     }, 100);
   });

2. Android Performance:

   .xb-compare-table {
     will-change: transform;
     transform: translateZ(0);
   }

Testing and Debugging

Mobile Testing Tools

1. Browser DevTools:

   • Chrome DevTools device simulation
   • Firefox responsive design mode
   • Safari Web Inspector

2. Real Device Testing:

   • Test on actual iOS and Android devices
   • Use different screen sizes
   • Test with different network conditions

3. Performance Monitoring:

   • Use browser performance tools
   • Monitor memory usage
   • Check network requests

Debug Steps

1. Check Console Errors:

   // Add error logging
   window.addEventListener('error', (e) => {
     console.error('Mobile error:', e.error);
   });

2. Network Debugging:

   • Check if all resources are loading
   • Monitor network requests
   • Test with slow connections

3. Layout Debugging:

   • Use browser dev tools to inspect elements
   • Check CSS media queries
   • Verify responsive breakpoints
