How to Transfer Contact from Andriod to iPhone or other (Crossplatform Contact Migration)
In this case, I am using Samsung TAB 4 (Source) and iPhone 7 (Target)
1. First, open native Contacts list on the Android Phone (Samsung etc..) > Setting
2. Then, tap on the Setting button and then tap "Import/Export"
3. Then, tap "Export to USB storage" or "Export to SD card" or "Export to SIM card" (Suggestion: "Export to SD card" )
4. The contacts will be exported to a VCF file on the storage as per above. send the file "Contacts.vcf" by mail to iPhone 7 (target) or by attaching a laptop and send by mail.
5. Download file "Contacts.vcf" in iPhone from mail.
6. In your iPhone 7, open the email and scroll down to the attachment and tap on file "Contacts.vcf" and choose add to contact
7. Some will be exported as per the format and you need to select "Create New Contact" for those who format does not match.
8. Check your contact details in iPhone 7. It should come in the contact list.
9. This can be done for any Andriod to any other phone by this Native feature and no need of any other tool.
