    Hello Geir,

    Sorry to hear you are running into issues- this is not something we've had reported before, which leads me to believe it is something device specific. What mobile device are you using and what type and version OS? And can you check your phone's settings and confirm that QR scanning is enabled in the camera app itself?

    Thank you,

    Hi Meghan

    I have Samsung Galaxy S20+ 5G SM-G986B/DS. Android 11. QR scanning is enable in camera app. See picture. I live in Norway so the words in the screenshot are in Norwegian language. I have also tried deleting the app, restarting the phone and installing the app and restarting the phone again and factory reset has also been tried. Nothing helps.

    Do you only receive that message when you try to scan a QR code with the CalTopo? When you aren't in the CalTopo app, are you able to use the camera to scan other QR codes successfully?

    Yes. I get that error code only in CalTopo app. In camera app i can scan other QR code. But not in CalTopo.

    And what about other apps besides CalTopo- are you able to scan QR codes from them? I've been doing some research on your specific device and there have been reports from other users that they can't scan QR codes from apps after updating their device.

    Based on what I'm finding, reports indicate that third party QR code scanners like the ones you named work but other apps like CalTopo do not. Do you have any apps that aren't third party QR code scanners like CalTopo that you can test? Sorry for the back and forth but I am trying tom determine if it is something happening with your device or if it is the CalTopo app itself, especially since we have not had any other reports of this behavior.

    Third party qr scanner? Then you get to find a qr scanner you want me to try because I can not download everything I find on google play and other sites.

    'QR and Barcode scanner' and 'Smart QR Code Scanner' are third party QR scanner apps. Based on your previous email, it sounds like these are able to scan QR codes from your device. My question is are you able to scan QR codes with any apps that are not third party QR scanners? For example, CalTopo is an app that is not a third party QR scanner app but has the ability to scan QR codes. Do you have any other apps like CalTopo that you can test out and compare?

    I found reports from other users with your specific device that are unable to scan QR codes from apps like CalTopo after updating their device. Again apologies for the back and forth but I want to rule this out first before we move onto other troubleshooting steps.

    Thank for your patience while we work through this.
