Contacts loading extremely slowly

[FusionCat]

Sharing this tip in case you have the same problem with your contacts loading slowly. I also faced low disk space problem when I had this issue. I found out my contact storage was taking GB of storage.

The solution is to simply just clear the cache (or data) of the "contact storage".
Do NOTE to sync/backup all your contacts with Google first as this method may clear any local stored contact.
