Memory is Full!

[lbandrew]

And it all seems to be in Contacts (over 10 GB) which seems impossible. I only have about 300 or so.
Also Contacts won't update with Google (because of lack of memory I presume). And I can't add any programs to copy them either, for the same reason. Question is, where can I see the actual file containing contacts to see whether there are lots of duplicates or some other reason that it could be taking up so much space????
I do have Samsung Kies (replacement Smart Switch) and have used it once. But can't find the file on my Mac.
Thanks for any knowledgeable suggestions. Or just ideas, I'm desperate!

Login to your Google account and see if your contacts list looks good there.
If so, on the phone disable contacts sync.
Then go to: Settings > Apps > All > Contacts > Force stop > Clear cache > Clear data
Enable contacts sync and let them sync back to the phone.

You should be OK.
