I recently had to replace my Samsung S5, the guy at the store had some trouble moving all of my contacts, texts, etc to my new phone. When all was said and done, it copied each contact over 84 times each. I know have 20000 contacts. Why did this happen? Is it a problem with how my cloud is setup ? Or something he did when connecting it to his little machine? Is there a way to quickly delete contacts? It's been weeks and I am only to the B's of deleting duplicate contacts. I HATE THIS PHONE! IT ALWAYS HAS A PROBLEM. Once again, the not so knowledgeable gentleman at the store, said he didn't know why it happened or what to do about it, other than remove them manually... and wished me luck. GRRRRRR
