When your phone finds contacts that can be merged, you’ll see a link notification when you open the Contacts app.
- On the Contacts tab, tap the Link suggestion notification when available. You'll see a list of suggested contacts to merge. Choose the contacts you want to merge. Some HTC phone models may not support this feature. If your phone doesn't have this feature, use your computer to access your Gmail. Gmail on the web allows you to merge duplicate contacts.
- Tap Menu > Manage contacts > De-duplicate contacts and follow the wizard.
