Richard has several platforms with different OSs, and he's having issues with maintaining contacts. He gets a lot of duplicates. Leo says that synchronization is a hard, universal problem. It guards against deleting anything, just in case. So you end up with duplicates. Leo uses Google Contacts. But even that doesn't solve the duplicates issue. But the sync is quite good. One solution that Leo recommends, that's iPhone only, is Sunshine. It can dedupe, as well as sync.
Joe has a Samsung Galaxy S10 and recently his contacts "came unglued" while text messaging. He couldn't see who he was texting in the middle of the conversation. Leo says that Samsung has its own apps for messaging, plus the Google versions. Leo would recommend replacing Samsung messages with Android Messages. That'll make it less confusing.
Rich has a need to remove contacts from his personal contacts account and then replace it in his business account. Leo says that he doesn't know any automated way to do that. The only real way is to do it manually. He recommends turning off syncing. Then export contacts as a CSV file. Clean up that contact list, then make a copy of the cleaned-up version. He can also use an app like Contacts+ to merge duplicates. Do this for both personal and business contact lists, then import them. Rich will likely have to do this periodically. But keep sync off.
David is having issues with contact duplications across multiple contact lists due to sync. What can he do to clean them up? Leo says to pick one contact list to clean up. You can use apps to find duplicates and merge them into a single contact. It'll take some time. Though Leo doesn't advise deleting old ones, in case you need to contact them someday. Once you've eliminated the dupes. SAVE IT. Back it up. It's your "canonical address book."
Tom wants to know how to share his contact information digitally with his smartphone. Leo says that there's plenty of programs that can scan his business cards (the standard is called VCF or VCard) and convert it to digital data. There's also a "share card" feature in the iPhone to share a VCF Vcard file via Bluetooth. Android has these options as well.
Doug wants to delete, merge, and generally clean up his contacts list on his Mac. Leo says there are a number of contact managers out there that will do this, but Leo's favorite on Mac and iOS is BusyContacts from BusyMac. It's not free, but there is a free trial, and it's a very nice contact manager. This will also pull in contacts from social media as well to keep things up to date.
Charlie still uses a Palm Tungsten E2. He also has an iPhone 5, but he prefers the way his Palm Pilot can sort his contacts by category. He's been having trouble syncing his Palm Pilot with his laptop, though. Leo says that the Palm Desktop software will probably work. But the Palm Pilot used a serial port and they aren't available anymore. So he'll have to pick up a serial to USB adapter. Leo thinks he should be able to do everything he wants with the iPhone, though, so let's try and find a solution so he doesn't have to carry both devices all the time.
Leo says that Android probably has the edge because it can merge with Google Contacts seamlessly, as well as Facebook and Twitter. He can customize the fields better, too. Leo advises to take all of his contact data and get it into Google contacts. Then, he's able to manage contacts well no matter what platform he's on.
