From your phone
Android’s stock phone app should be the first thing to try. Go to your Contacts – we tried this on LG and Samsung phones, but depending on your phone’s brand it can be a little different – on the app, tap the Menu button > Manage Contacts > then select Merge. A screen with all repeated contacts will show up, so you can confirm which you want to merge one by one.
From your desktop browser / Google Contacts
A second method is made available from your Google Account. Log in to your Gmail Account and then go to your Contacts (or enter directly from this link). On the right sidebar there’s a “Duplicates” option, which will show a list with all the candidates to be merged. Select “Merge” on each and you’re done.
An additional word of caution
The two alternatives above are easy and accessible default options that Google provides to merge contacts. Unless you have thousands of contacts and hundreds of duplicates, they should serve you well. But an additional word of caution. There are a ton of “free” apps on the Play Store to merge contacts, however even if some of those promise to automatically merge with one click, we wouldn’t compromise on security by letting a third-party ask for Google account credentials solely for this purpose.
