Merge contacts using the Google Contacts app

The first and easiest way to solve the problem is where the problem originated. You can easily edit and merge the duplicate contacts in Android. Unfortunately, this looks a little different for every smartphone manufacturer.

If you use the Google contacts app, as found on Pixel smartphones and other devices with pure Android, merging is very easy. Hold your finger on the first contact you want to merge with others. The app then changes to mark mode. Now you just tap on the other contacts to merge. Once you have marked all of them, open the menu (three dots in the top right corner) and tap on Merge  

If you make a mistake while merging the contacts, you can simply disconnect them again. To do this, go to the combined contact, open the menu and tap on Show  linked contacts.  Here then selects  link  at picking up.

With Samsung’s Contacts app on One Ui, merging contacts works similarly to Google. First open one of the contacts from those you want to merge. Then open the menu in the top right corner and tap Link another contact.

Then you come to a selection screen where you can mark the contacts that you want to connect with the selected one. Once you have marked all, you only go to the link for confirmation  As you can see from the multiple selection at Samsung, the merging of double contacts in Android can be solved in different elegant ways. If you have a smartphone from LG or Sony, the menu entries will have a slightly different name, but the process is not very different from the ones described above.

Samsung’s phone book also makes intelligent assumptions about which contacts you want to link together. It doesn’t matter whether they were stored on the SIM card, in the Google cloud, in the Samsung cloud or on the phone memory. The contacts app merges duplicate contacts from all sources. The app usually suggests this to you at the first start, but also from time to time. 

Delete duplicate contacts in the Google web service

Google has developed a website especially for contact management, with which you can conveniently bring your contacts together from the computer using the mouse and keyboard on the large screen. Of course, this assumes that you have synchronized all your contacts with Google. At Samsung you also have to move the device contacts to Google. You can find out more about securing contacts in the cloud here .

As soon as all your contacts have landed on Google’s servers, you can manage them from all devices on which you log in with your Google account. Accordingly, you can now sit on the computer, go to the following website and register:
