Hello everyone! I have an issue that has been puzzling me a little. My mother has a Samsung Galaxy J3 and my father liked it, so he bought one as well. They both use their own SIM cards, in their respective phones and don't share any accounts other than a Facebook page. However, my dad suddenly ended up with all my mom's contacts and phone numbers. And when he deleted them they disappeared from her phone as well. On the other hand, all his contacts didn't get on my mother's phone. So it seems to be a one sided thing.. I can't figure out for the life of me how the two phones got synchronised and can't think of how to fix it. Can someone maybe help? Thanks!
