I was helping my mom setup her new phone, I put in the sim card and each name has a duplicate with 1 number and 1 Whatsapp. I think there's some with Gmail as well. How do I combine it? I tried using GO Ex Contacts but it couldn't merge, it said there were no duplicates found, except 1 but with that contact both were numbers. There's about 400 contacts at the moment so it's gonna be a real pain to do it individually. Anyone know a fix? The phone is Samsung Galaxy Trend Plus.
