The fingerprint issue has been going on for awhile. It was reportedly worked on for R 1.10. But issue still persists. I reported it here Week 18. 2023: Development and Testing Updates - /e/OS Smartphone Operating System / Development Updates - /e/OS community. It happens to my wife’s phone and mine; we both have the 7T. I still need to report the bug in GitLab. As you can see in the Week 21 update the touchscreen issue is a known problem that seems to be caused by the partition files referencing Android 13 and not matching the install files of /e/ OS version S (Android 12). Should be fixed with /e/ OS T (Android 13).
Since /e/ OS S doesn’t work yet on the 7T I decided to install LinageOS 20 on my 7T. LineageOS 20 has Android 13. So far so good. No touchscreen issues and no fingerprint issues. I’ll likely go back to /e/ OS when T is released and the touchscreen and fingerprint reader work as they should.
