Signal-desktop: Unable to scan QR Code using in-app scanner.

[dstoeckel]

I am unable to scan the Signal-Desktop QR code during device registration using Signal.
This is independent of the used monitor and also does not work from a printout.

I am using a _Samsung Galaxy SII_.

Scanning the code using _Barcode Scanner_ (https://play.google.com/store/apps/details?id=com.google.zxing.client.android&hl=de) works flawlessly.

Reproducibility: Always

Expected Behavior: Can scan the QR code or enter a token manually.

This is an Android issue and it's already tracked here https://github.com/WhisperSystems/Signal-Android/issues/4637 so you can close this issue here, thanks

This issue shouldn't be closed! The newest upgrade has destroyed my day. Cannot relink the signal app because of the bad coded qr camera in signal.

@ab-in Did you try any of the workarounds from the linked issue? Tapping to force it to try to focus, perhaps? Making the Signal Desktop window bigger, for a higher-resolution image of the QR code?

Thank you for quick response. I got it on classic way but it was precision
work. I had to first switch native qr app on, find a position of the camera
and that switch to signals qr. On my phone Signal has no restrictions. But
also voice msg dosn't work. I can make one and send. But if somebody else
send me a voice msg, I ca't play it. An error appears.
I love Signal.
Huawei Mate 10 Pro Dual - is my phone.

Regards
Anna

What I had to do was open Signal then go to settings and then scan the code INTO Signal....bingo they synced up....

You mean open Signal on your mobile phone (iOS or Android) and then scan the code? That is the standard way to link a Signal Desktop app to your Signal app on your phone. What steps did you do before?

sorry for the confusion...I was trying to install Signal on my desktop and in doing so it opened a window with the QR code and asked for me to scan it...it wouldn't work...BUT when I opened Signal on my phone THEN scanned my desktop....bingo
