It looks blurry rarely on some android devices

[CarlosEco]

Hi, i´m using ZXingScannerView and screen looks blurry only in some huawei devices like you can see in this image:

The library import is:

implementation 'com.journeyapps:zxing-android-embedded:3.6.0'

The tag that i´m using on my xml is:

The issue template is important - please don't delete it.

Specifically:

1. Does the same happen in the sample project?
2. Does the same happen in the Barcode Scanner application?

For this case, check the resolution sizes in the the logs (adb logcat). The relevant section should look something like this:

The most likely issue is that a suitable preview size isn't found, but the logs should confirm whether that is the case.
