[Android] com.google.zxing.NotFoundException on Tablet Samsung Galaxy A7 (Android 11)

[jmonaniat]

Description of the problem:

Lib/sdk does not scan QR code on Samsung Tablet "Samsung Galaxy A7". Library keeps throwing Error in decodeCameraXImage- com.google.zxing.NotFoundException when decoding QR code (same QR code works on other devices including Samsung Tab A5, S10 and various other devices tested so far, this is the first device it fails).

code: result = reader!!.decode(binaryBitmap).text

Which library version are you using? E.g. 3.2.0. 4.1.0

Which phone/tablet are you using, and which Android version does it run? (e.g. Samsung Galaxy S5, Android 5.0) Tablet Samsung Galaxy A7 Android 11

Does the same happen on other devices or an emulator? No

Can you reproduce the issue in the sample project included with the library? If not, can you provide your own sample project or sample code that produces this error? reproducible

package com.google.zxing; public final class MultiFormatReader implements Reader {

-- /**

• This version of decode honors the intent of Reader.decode(BinaryBitmap) in that it
• passes null as a hint to the decoders. However, that makes it inefficient to call repeatedly.
• Use setHints() followed by decodeWithState() for continuous scan applications.
• @param image The pixel data to decode
• @return The contents of the image
• @throws NotFoundException Any errors which occurred */ @Override public Result decode(BinaryBitmap image) throws NotFoundException { setHints(null); return decodeInternal(image); }

---

In the case of an error do you have a stack trace or adb logs? Error in decoding image- com.google.zxing.NotFoundException

@rkistner @Servus7 & team, any luck looking into this?

it works while scanning with the ZXing's "Barcode Scanner" app but not via the QRCodeMultiReader i have tried.

Unfortunately I switched to iOS development some years ago and im not up to date with android. Could you create an PR for this issue?

@Servus7 thanks for getting back on this, is it possible to assign to right team/dev who can address this ticket?
