Fix QR Code Problems: How to Solve QR Code Issues? 

QR Codes are a powerful tool for sharing information. They help in connecting users to websites and simplifying processes. 

But what happens when your QR Code won’t scan? Or worse, what if the QR Code is blurry or just not working at all? These issues can be frustrating, especially when you rely on these QR Codes for business or personal use.

In today’s guide, we will help you understand why your QR Code is not working and provide clear solutions to fix QR Code. 

Plus, you’ll also learn awesome tips to create QR Codes that work flawlessly.

So, let’s get straight to it.

A. Why Is my QR Code not working? (Common Reasons)

QR Codes are the brand ambassadors of convenience, yet they sometimes find themselves in difficult situations. 

If, at any point, you have asked yourself, “Why won’t my phone scan a QR Code?” or “Why is my camera not scanning QR Codes?” don’t worry, you’re not alone. 

Let’s take a look at some of the main reasons for this:

1. Blurry QR Code

A blurry QR Code is one of the most common reasons why a QR Code might not scan. Smartphone cameras often fail to recognize blurry or pixelated QR Codes. 

This could be because the QR Code was printed in low resolution or that it was scaled incorrectly.

How to fix QR Code? Always use a high-resolution image when printing or sharing QR Codes. If you’re generating a QR Code, choose the right file format that stays sharp, even when resized.

2. Incorrect QR Code size

QR Codes that are too small can be difficult to scan. While it might be tempting to make them compact, smaller sizes can sometimes compromise functionality.

How to fix QR Code? In general, QR Codes should be at least 1 x 1 inch for most use cases. For big posters or billboards, the size should increase proportionally (think 10:1; if a QR Code is to be scanned from a distance of 100 cm, it must be at least 10 cm wide).

3. Low-contrast QR Codes

QR Code scanners detect the contrast between dark and light areas of the QR. Using non-standard colors, gradients, or low contrast can confuse the scanning devices.

How to fix QR Code? Go for traditional black and white QR Codes, or be sure that your foreground and background colors have a differentiating contrast. Also, avoid decorative or overly creative designs.

4. Damaged QR Code

Printed QR Codes end up in all sorts of places. They’re bound to face wear and tear. 

A scratched or torn QR Code will just not read. Even minimal damage to the pattern can sometimes render the code unscanable.

How to fix QR Code? For printed QR Codes, laminate them or install them in locations that will not expose them to excessive wear and tear.

5. Camera problems

Sometimes, the problem is not the QR Code but the device trying to read it. Dust on the camera lens, lack of light, or out-of-date camera software can sometimes cause scanning errors.

How to fix QR Code? Clean your camera lens and ensure proper lighting while scanning the QR. Also, make sure your device’s software is up to date. If your phone won’t scan QR Codes, try using tools like Google Lens instead of the native camera.

6. Outdated QR Code

If your QR Code links to a URL or resource that no longer exists, the QR Code is basically useless. 

If you see these errors while scanning QR Codes, it might be because the QR Code has expired or the business has stopped hosting the URL or file.

How to fix QR Code? Double-check the URLs or links embedded in the QR Code. Always test your QR Code before deploying it to make sure that it leads to active and functional content.

7. Poor QR Code placement

QR Code placement plays a vital role in ensuring its scanning ability. QR Codes that are placed on reflective surfaces, curved objects, or areas with glare can cause issues. 

Scanners may not be able to read them properly due to distortions or reflections. 

How to fix QR Code? Avoid placing QR Codes on shiny or reflective materials. If you must, consider adding a matte finish or repositioning the QR Code for easier scanning.

8. Unsupported phones

If you’re using a very old QR Code scanner or other types of older gadgets, QR code scanning may cause issues. 

Some older Android or IOS devices might require a specific third-party app to scan QR Codes correctly.

How to fix QR Code? If QR Codes are generally not recognized by your phone, try updating or downloading a new QR Code Scanner app. This will solve all issues. If not, you can always go for Google Lens.

B. How to Fix a QR Code

If you’re still sitting in frustration screaming at your screen, “My QR Code is not working,” here’s how you can troubleshoot and resolve QR Code issues generally:

1. Fix the QR Code resolution

First things first, see if your QR Code image is blurry or not as crisp as it should be. If it is indeed blurry, just hop on to your QR service provider and export the QR Code image in the right format.

If you have not opted for a service provider and used a one-time QR Code solution, just create a new (free) QR Code and, this time, export it in the right resolution.

Make sure the image is high resolution (minimum 300 DPI). If needed, reprint the QR Code with better quality.

Also, if you’re adding the QR Code to your predesigned posters or projects, avoid stretching or resizing the image disproportionately.

2. Adjust the size

If you’re wondering how small can a QR Code be, well, make sure the QR is at least 1 x 1 inch (2.5 x 2.5 cm) for scanning from close distances.

For QR Codes that are to be scanned from a farther distance, make them larger.

3. Improve contrast

Go basic! Use black for the QR Code and a white background. If you want the QR Code to match your brand or personal theme, go for colors on the farther ends of your pallet. 

By that I mean go for colors that are polar opposites of each other (Think maroon and yellow). Match light color backgrounds with dark-colored QR patterns.

Avoid using light colors or complex patterns that reduce contrast.

4. Test the QR Code

Before deploying the QR Code, use different devices and apps to test the code. Ask others to scan the QR Code to ensure it works across platforms.

If your QR Code is not working on Android, use a third-party QR Code scanner because sometimes the default camera app might cause scanning errors.

5. Ensure the link is active

Double-check the URL linked to the QR Code. Make sure the QR Code points to active, correct, and relevant data. 

Also, see if your QR Code has expired or is active only for a limited time. 

Pro Tip: You can use tools like Scanova to create QR Codes that can be updated in real time and can be set to active or inactive based on your needs.

6. Optimize placement

Make sure you follow the best practices for QR Code placement. Place the QR Code on flat, non-reflective surfaces.

Avoid curved objects or locations with glare because that can sometimes cause errors. Also, 

7. Fix phone issues

• If your phone won’t scan the QR Code, try cleaning the lens. 
• If the issue still persists, try updating the camera app or using a dedicated QR Code scanner.
• For iPhone users, ensure your camera is set to scan QR Codes in settings. (Although this setting is already tuned on by default for most models but still give it a check just to be safe)
• For Android users, update your phone or download a reliable QR Code scanner app if the QR Code not working on Android.

C. How to ensure your QR Codes work flawlessly?

1. Use a reliable QR Code generator

If you want your QR Codes to work right, go for tools like Scanova that offer high-quality, customizable QR Codes. 

With Scanova, you can create QR Codes for URLs, business cards, menus, and much more.

2. Keep it simple

Do not over-customize the QR Code. An overcrowded QR Code will cause scanning errors. While colors and logos add branding, make sure the code is still scannable.

3. Ensure high resolution

Always download QR Codes in high-resolution formats such as SVG and EPS, which are preferred choices for graphic designers. 

These QR Code file formats can be scaled to suit any use case, especially when printing. (Be it a small poster or a big billboard)

4. Test thoroughly

Test, test and test the QR Code before deploying it across different devices and platforms. This will help you avoid any unwanted surprises later.

5. Add clear CTAs

A QR Code without a call-to-action is often invisible to the users. A call-to-action teaches users on what to expect when scanning the code. 

Or it can simply guide users on what to do with the QR Code. (Let’s be real; not everyone is as tech0friendly as everyone else)

Effective Call-to-Action examples:

• “Scan to Learn More”
• “Scan to Save 10%”
• “Scan to View the Video”

Where to put the CTA: Put the call-to-action above or below the QR Code in bold, easily readable text. A CTA could be a text as simple as a “Scan Me” message.

6. Use dynamic QR Codes (whenever possible)

Dynamic QR Codes can be easily edited or updated even after they’ve been printed. Plus, you can track their usage. So that is more campaign-friendly.

Pro Tip: With dynamic QR Codes, you can get insights such as when, where, and how many times your QR Code was scanned. You also get to know which devices or browsers were used to access the QR Code. This can help you make data-driven decisions to optimize your future campaigns.
