My site works smoothly on desktop, yet on phones and tablets—both iOS and Android—it will sometimes lock up for 15-30 seconds right after any internal link is tapped. The hang is unpredictable; I cannot tie it to a specific page or element. I have reproduced it in Safari, Chrome and Edge on mobile, but never on desktop equivalents. I’m looking for someone who can dig in, trace the root cause and eliminate the pause entirely. You’ll probably need to profile JavaScript execution, network requests and repaint times with tools such as Chrome DevTools, Safari Web Inspector or similar mobile debuggers, then patch the offending code (or recommend lightweight alternatives if third-party scripts are involved). Deliverables • Technical summary explaining what caused the freeze • Clean, committed code fixes or configuration changes • Confirmation that taps navigate instantly (≤1 s) on iOS and Android in Safari, Chrome and Edge • Brief test report outlining the steps and results on each browser / OS combo If you’ve solved intermittent performance glitches like this before, I’d love to get this wrapped up quickly so users never feel the lag again.
