Hello, Jonathan SSerugga.
Welcome to Microsoft Community!
I have noticed that you have already performed a reset for your Surface Duo 2 but still failed to resolve the issue.
Reset has almost been the last option for this type of issue and if the problem still persists, I would recommend you to get in touch with Surface Technical Support team for a more efficient service to resolve it.
I am sharing the steps to create a service order with you here:
- Use your personal Microsoft account (not your organization account) to access the following links:
- Type Surface Duo 2 Fingerprints not working, press Enter, and click "Contact Support" at the bottom:
- Select Technical Support and select the device model (Surface Duo) you are currently using in Product family, then click Confirm:
- You will see contact options for Chat support and Phone support, please contact them during business hours:
I hope your issue can be dealt with appropriately.
I wish you all the best.
Best Regards.
