Why won't my Phone contacts transfer via google

[AC Question]

Recently got a new phone, Vodafone Smart Ultra 6, and tried to transfer contacts across from and old sony xperia s, using the google sync tool, but none of the phone contacts came across, only basic email contacts, despite having checked both phones are linking to the correct account, and that the sync is on, please help!

Welcome to Android Central! What Google sync tool are you referring to?

On the old Sony phone, what account are all of your contacts saved to? Your Google account or the local Phone account?

(IOW, only contacts saved to the Google account will sync. If they're Phone, SIM or Device, export them, then import that file to Google Contacts.)
