I have two iPhone users who reported a barcode scanning issue.
Some barcodes can no longer be scanned, even though there were no problems before.
They are encoded in CODE128, but I doubt that this is the root cause. It might be related to barcode density or a focus issue specific to iPhones, but what is most surprising is that the problem has only appeared in the last 2 or 3 days.
On Android devices, everything works normally.
Has anyone in the community experienced this issue?
There is a setting on the iPhone under the Camera settings to allow for QR scanning specifically. Make sure it is turned on. Can you check if that is not the problem.
Otherwise you can contact the Support team (if you have a license) for the resolution of your issue by following the below steps:
There are now 3 iPhone users who have reported an issue when scanning certain barcodes with their iPhone. Two of them are using an iPhone 13, and another one is using an iPhone 15.
I personally ran a test with an iPhone 13 and encountered the same issue, whereas everything was working normally last week and QR scanning is enabled under camera settings.
My application is used to scan two types of barcodes printed on documents. Only one of these two barcodes can no longer be scanned.
I will record a video so that you can see the issue and send it to the support team.
Hi David,
Thank you for uploading the videos and also confirming you’re able to scan the barcode in the link.
We did have a recent change made to the iOS barcode scanner that was meant to address issues related to the camera focus.
It seems like the change also caused some degradation in some devices, which in combination with the lower quality of the barcode made it not scannable in your case.
I’m hesitant to roll back the change, since we don’t have an indication this issue is wide spread.
I’m still looking into this and trying to find a better solution, I’ll post here when I have updates.
The problem still occurs with iPhones 13 or 15. You should have noticed it yourself by printing the barcode image posted earlier in this thread at exact scale.
If you cannot find a solution quickly, please roll back to the previous version, which was working correctly.
Hi @DavidFr27500,
We still don’t have a solution, I will update here once we do. However, it is not likely to be in a matter of days.
We do have multiple confirmations the recent change resolved the focus issues it was trying to address, so a simple rollback is problematic here.
I understand your frustration, and I’m sorry we don’t have an immediate solution.
Has anyone seen an improvement with the iPhone focus issue after the latest update?
Based on feedback from users of my app, there doesn’t seem to be any noticeable improvement on iPhone 16, 16e, or 17. Some barcodes still can’t be read at all on iPhone 13 or iPhone 15.
That said, my own testing is limited to only two barcode types, so this might not reflect the general situation.
The document that users of my app need to scan comes from an official entity. It’s a 38-character code containing several pieces of information.
If I could print the barcode myself, changing the format or reducing the density would certainly fix the problem.
While the Appsheet team works on a solution, I can only offer users two options: either change their phone or enable the Scandit option in their app.
Since Scandit can be tested for one month, I’ve been able to help users who were stuck, but soon the trial period will expire, and Scandit represents a high cost, especially for my users who are very small family business owners.
I’m not sure how it would be possible, but has a group already been – or could one be – created to share the costs of accessing Scandit?
