Which business-card fields fail most often in real scans?

I’m looking for workflow-level feedback on BizCard Go, not votes. If you handle cards from events, sales meetings, or client visits, please try 3–5 fictional or redacted English or Chinese cards.

Suggested test: scan or upload, correct any OCR mistakes, search for one contact later, and export the records. Which names, companies, titles, phone numbers, addresses, or card layouts fail most often? Where does scan → review → search → export feel unclear?

Android closed test: first join https://groups.google.com/g/testers-community, then opt in at https://play.google.com/apps/testing/com.simonchow.bizcardgo

Please report reproducible OCR or workflow issues at https://bizcard.simon-gpt.com/support and include source code BC-PHF. Do not share private card data; use fictional cards or redact screenshots.
