Resizing a desktop browser window gives a rough approximation of a mobile layout, but it doesn’t reproduce real touch behaviour, actual device pixel density, or the specific viewport quirks of a genuine phone or tablet, which is why a page that looks fine when you shrink your browser can still break in ways only a real device sweep catches. Touch targets that are technically clickable but too small to comfortably tap, elements that shift unexpectedly when the on-screen keyboard appears, and content that scrolls awkwardly on a genuine touchscreen are all things a desktop resize simply cannot reveal, however carefully it’s done.
Why testing one device won’t tell you much
Checking your own phone tells you about that one phone; the actual value of this service is in covering the range of sizes and devices you realistically can’t test individually before ordering.
If you already suspect a specific page behaves badly on mobile, mentioning it upfront means we can prioritise confirming and fixing that one first, rather than treating every page as equally unknown.
It’s also worth thinking about which pages carry the most weight for mobile visitors specifically, since a checkout or contact form failing on mobile matters more urgently than a decorative element on a rarely-visited page. Given how much traffic now arrives on a phone rather than a desktop for most sites, a mobile-specific issue often affects a larger share of visitors than an equivalent desktop one, even though it can feel less visible day to day. That gap between perceived and actual importance is exactly why a dedicated sweep tends to be worthwhile.
Mobile & tablet viewport QA sweep
A structured sweep across the phone and tablet sizes your visitors actually use, catching layout issues a quick desktop resize won't reveal.

This or something else?
| You want a structured check across phone and tablet sizes generally | This fix covers it |
| You already know a specific page breaks at a specific screen width | Responsive breakpoint repair, a more targeted fix |
| The mobile menu specifically is what’s not working | Menu not displaying or breaking on mobile |
| You want desktop browser rendering checked, not mobile viewports | Cross-browser rendering audit & fix list, a different service |
| The site is unusable on mobile entirely, not just displaying imperfectly | A more urgent, targeted diagnosis |
What we need from you
- The key pages or user flows you most want checked on mobile and tablet
- Any specific devices your customers have mentioned issues on, if known
- Whether you want issues fixed as found, or a full report before any changes
What we do
- Test the specified pages across a representative range of phone and tablet sizes
- Check touch interactions specifically, not just visual layout at each size
- Document every issue found, with screenshots and the specific size or device involved
- Prioritise the list by how disruptive each issue is to actually using the page
- Fix straightforward, low-risk issues directly where the cause is clear
- Deliver a written report covering findings, fixes made, and anything needing a decision
What is included
- A structured sweep across representative phone and tablet sizes
- Touch interaction testing, not just static visual layout
- Straightforward, low-risk issues fixed directly
- A written report prioritising findings by real disruption to actual use
Not included
- Fixing every issue found, if some require a larger follow-up decision from you
- Testing every physical device model that exists, which isn’t practically possible
- Ongoing monitoring as new device sizes are released
- A mobile-first redesign, as distinct from fixing what’s currently broken
Questions about this fix
Is this the same as just resizing my browser window?
No — that only approximates layout, not actual touch behaviour or real device rendering quirks, which is exactly the gap this sweep is built to catch.
Will you test my specific phone model?
We test a representative range covering common sizes and operating systems rather than every individual model, though we'll prioritise anything you specifically mention.
Does this include tablets in landscape as well as portrait?
Yes, both orientations are checked where relevant, since a layout that works in one can still break in the other.
What if the report finds nothing wrong?
Then you have real confirmation your mobile experience holds up, which is a genuinely useful outcome in its own right, not a wasted check.
Will this improve my mobile search ranking?
Indirectly, since a broken mobile experience can hurt engagement signals, but this is a usability check, not a dedicated SEO service.

A bad update breaking the site is a symptom of updates not being tested first. Care plans run every update on a staging clone before it reaches your live site, which is the actual fix for this happening again.
Your access, your rules
Create a separate admin account for us and delete it when we are done. For anything else, we get in touch and agree a method — never a form field on this site, never by reply to an email.
We back up first, always
Before anything is touched we take a full backup and keep it for 30 days. If a fix goes wrong, we put the site back exactly as it was.
If it is not what you bought
If the problem turns out smaller than what you ordered, we refund the difference. If it is bigger, we stop and send a quote before doing any extra work.
If we cannot fix it
You get back what we received. Diagnosis is on us — you only pay when the problem is actually solved. The payment processor takes its fee before the money reaches us, so we never hold it and it is not ours to return. That is true here as everywhere else.
If it comes back
Reply within seven days of delivery and we put it back on the bench at no cost. The fix is not finished until it holds.
What we are responsible for
If something goes wrong with a fix, our responsibility is limited to what you paid for it. We take a full backup first so mistakes can be undone, and we tell you before doing anything outside what you bought.
