Many iPhone users face issues with duplicate contacts after syncing contacts, importing VCF files, or switching to new iPhones. Manually deleting them is time-consuming and also risky. A safe option is to use a professional tool like
BitRecover vCard Duplicate Remover, which helps you scan, preview, and remove duplicate contacts easily. It allows selective deletion, works in bulk, and keeps your original contacts safe, making the cleanup process simple and stress-free. I tried to delete duplicate contacts from iPhone manually, but I failed and wasted my time.
