Barcode reader not work

Hi! 

I recently create a canvas app on Power Apps, it implements the barcode reader, the problem is that I already test it in many phones and in almost all of them it works, but in some specific models it doesn't detect the QR code. I'm using Oppo A93 and the scan opens fine but it doesn't detect any QR code. I also tried in other models and the scanner work properly in the native camera but not inside Power apps.

Hi @Ferjimenez ,

 

Please check these limitations.

Best practices and scanning constraints

1.Ensure a distance of 7-10 inch and slowly move the device in this range to speed up the scan rates
2.Need to hold the phone in the locked orientation (portrait) to scan successfully.
3.Barcode labels need a min height of 1inch and min width of 1.5 inch to ensure high success rates.

Known limitations

1.The app needs to lock down a certain barcode type or expose to the user the option to choose the type before scanning.
2.On mobile players (Android, iOs) the camera preview has a locked ratio (does not stretch to full width available).
3.Long barcodes (15+ characters like I2O5) with low quality labels can give trimmed/erroneous scan values while scanning from a different distance/light conditions, etc.
4.The barcode control needs to have a height of 500x 700 or higher. Further on, iOS has lower success rates than Android devices due to memory limitations. Please set the scanner width and height to 640×700 or lower and scan rate of 30 to avoid such errors.
5.Scan rate needs to be set at 35 rather than 60 (the default) to ensure an optimal memory utilization.
6.When running the app long time/ locking unlocking the scanner can freeze sporadically, need to restart the app to recover.

 

If the problem still exists,  I suggest you create a support ticket for professional assistance following the below procedure.

Hi,

I had a similar problem as you and the only solution I found was to use the retired Barcodescanner.
You can access it by editing your application then: Settings->Upcoming Features->Retired->Legacy Barcode Scanner

When enabling this option it will show in the insert(+) section.
Although this isn't a permanent solution since BarcodesScanner is retired and will be removed it works for now!


Hope this helps.  If it did please tag it as the solution 🙂

Hi,

 

I'm having a similar problem ussing the barcode reader tool, works fine on IOS but cant get it to work for my Honor 7A.

 

It doesn't recognise QR codes and i have checked all the parameters. Is this an issue for all non IOS systems? 

Thanks for so much detail. A couple of questions:

1. Where is the scan rate set in Powerapps? I have options on the barcode reader for scan quality (high, medium, low, etc.) but I do not see properties for rate.

2. How would the physical size of the control in pixels affect its scanning ability?

I have an issue with a Blu View 4 Phone, neither the legacy reader nor the current reader works, Anybody have a similar experience or try a Blu View 4 phone?

- Thanks
