Barcode reader camera doesn't detect QR code

Dear team,

 

I study Power app recently, i would like to create function to read the QR code value first, then i'll reseach how to use that value later.

This is what i set-up :

Thanh_Mai_1-1744701199633.png

 

- BarcodeReader1:
Control: BarcodeReader@1.0.23
Properties:
BarcodeType: ='BarcodeReader.BarcodeType'.QRCode
Height: =68
OnScan: =Set(scannedLocID, First(BarcodeReader1.Barcodes).Value)
ScanningMode: ='BarcodeReader.ScanningMode'.SelectToScan
Text: ="T4"
Width: =170
X: =159
Y: =120

 

When i press the scanning button on my app, the camera appears but can not detect the Qr code, i tried many method, from desktop to paper. There're other apps (not power app)on my phone have QR scanningfunction and they're all work normal.

Could you help me on this issue? Thank you in advanced!

1 ACCEPTED SOLUTION

Dear Hammad,

 

Unfortunately, i don't have solution

1. Power app on my device (Oppo mobile)  doesn't recognize QR code and Barcode, with other mobile apps as banking,company's app, social network apps,...my device works normal with QR code detection .

2. I use other device (Samsung mobile) to test, Power Apps Barcode reader function works normal on this Samsung device.

So the root cause is the Camera on the device is not compatible with Power App.

It looks like you were facing issues with your barcode Reader in Power app. As you mentioned you were able to test the app and it works fine, can you please mark the helpful reply or give a pointer from your side and mark it as solution so that other community members can find it easily.
