barcode-reader-mobile-samples's Issues

App crashed while decoding barcode

Hi, we are using your SDK about 1 years.
But one is not seeming resolved since then.

Heap corruption detected, free list is damaged at ### *** Incorrect guard value: ###

We have this error for some device from day 1.
Could you please look at this and give us some idea that how can we solve ?

App bug

While scanning a basic QR code an error stop the process (Barcode Scanner X v.9.4.0 & Android 7.0 MIUI 11):
[Attention(exceptionCode:-10004)] *ttps:/**emp**l.**m/u*16*b*rti*a*ta-c6691f***0/

Barcode scanned result is not working

When I am scanning PDF 417 format barcodes, I get the results as encoded.
example:
I expect the result to be "First name: xyz123" , but I get "First name: xyz2* ",
This seems to happen only with react-native version 0.69.3, earlier react-native version was 0.64.2, even now this old version code works fine but not the updated project and the dynamsoft barcode reader version that I am using is 9.2.2

Default settings not in pair with your Web application

Hello there!

The scanning results with your mobile application are not as good as your web application demo with its different default settings:
https://demo.dynamsoft.com/barcode-reader/
The default settings should be unified, similar among all your demo applications IMHO.

And i would add that some Best Coverage default settings should be enhanced:
FurtherModes

• BarcodeComplementModes --> Auto
• ImagePreprocessingModes --> GrayEqualize --> Sensitivity --> 8
• TextureDetectionModes --> GeneralWidthConcentration --> Sensitivity --> 9
• BarcodeColourModes --> DarkOnLight + LightOnDark + DarkOnDark

Add more Additional Settings

At least some of them:

• BarcodeComplementModes
• ImagePreprocessingModes
• TextureDetectionModes
• BarcodeColourModes
