Troubleshooting a QR Code reader that is not working

Updated November 2, 2017

One of the problems with scanning a QR code is that free apps that are available to read them vary greatly. There are a lot of old, really poorly built apps available in the app stores today. Here is a short post with suggestions for getting a good QR Code reader and setting it up properly, not only for Plants Map tags and signs, but for any QR Code you scan.

I’ve written about that before in this article. I just wanted to cut to the chase here and share what I do with my Samsung Galaxy S5 Android phone and maybe it will help you if you are having problems.

The QR code engraved on Plants Map signs and tags is simply an image or picture that your smartphone can turn into website address. Just like you might type into your browser to go to do a search at Googe, with a QR code, you would scan the code and it would interpret the image as being the web address for Google and your phone or mobile device opens your browser and takes you to that page.

Setting up your QR Code reader

I use this scanner available from I use the $1.99 “Pro” version because I think it is much faster.

QR Code troubleshootingThe first thing I did after I downloaded the app was go up to the top right and open the settings page. I made sure the box is not checked for “ask before opening” because I want to just go straight to the webpage. I also don’t check “make a sound” so it doesn’t beep every time I use it.

Most importantly, I make sure the box for using the in-app browser is NOT checked.

This last checkbox causes the web page to open in my default browser on my phone. This is important. If you have an app that isn’t working, most likely the app has its own browser and there is a problem with it remembering web pages you’ve scanned before and storing those in the cache.

I attached a screenshot of my settings screen. I would recommend getting an app, either the free one or the paid one from Scan.Me and adjusting your settings like the photo above and you should be all set.
