Nexus 5X, https://play.google.com/store/apps/details?id=com.gamma.scan

Tried up close and far away. Neither scans. As long as something like this has a reasonable chance of going wrong (like it did with me), even though it may work for many people, it shouldn't be implemented.

No flippin' way. This thing wants way too many permissions.
For a dedicated QR reader, I use the one from Gamma Play, if anyone can name a better one.
They have a free version and a Pro version, which sometimes goes on sale for free as well.
It uses no more permissions than it needs, to access the camera and the internet to resolve links.

eBay acquired the company and technology and the SDK was closed thereafter. The company shut down their app in December 2015.

There are plenty of alternatives, I use this one: QR Code and Barcode scanner

On my Redmi 7A mobile, the QR scanner app I have is called "Scanner". It came pre-installed, I can't find it on Google Play.

However there a ton of QR scanners on Google Play, a lot of which are highly rated.

This is one:

No worry, that's not a stupid question! There are apps that let you use an image you saved and scan it directly via your phone! So

1. Save the image of the code first in your phone (you can ever take a screenshot of it).

2. Download and open an QR code scanner app.

3. Check the different options. There should be one to scan with your camera and one to scan an image you already have in your phone.

Here I use that one - its free: https://play.google.com/store/apps/details?id=com.gamma.scan

4. Accept to join the server 🧡😁🌷

Are you scanning the numbers or barcodes? If the former try an actual barcode scanner. This app lets you copy/paste multiple barcodes. It seemed to work well even with blurry photos.

Try either of these apps. Both have an option to disable auto focus.

I use this one from Google Play, which have some annoying ads from time to time, mostly because it was the first result when I searched for one. There's probably better (and open?) alternatives out there.

My coworker noticed some users of our QR & Barcode Scanner app https://play.google.com/store/apps/details?id=com.gamma.scan to complain about such strange issues and he investigated them. Now we published an update which should be live soon that works around this issue...

I highly recommend using this QR Scanner app. It scans QR code very fast. Have been using it for years now.

I use this app and it has an option to scan from an image file

This apps only need net for ads, no other functionality. Sorry if someone thinks this is self promo for my apps, I just try to make quality apps people find useful in every day life. Don't really make much money from them either. It's more like a hobby.
