Seeing the same contact appear multiple times on your OnePlus 15 can quickly turn your phonebook into a mess. Calls may show the wrong name, messaging apps can behave oddly, and syncing becomes confusing. This problem is common on Android phones and is usually tied to account syncing or how contacts are displayed.
Why Your OnePlus 15 Is Showing Duplicate Contacts
- Contacts are synced from multiple accounts like Google, WhatsApp, or SIM.
- The same contact exists on the phone storage and a cloud account.
- Sync errors occurred after a software update or account sign-in.
- Contact display settings are showing all sources at once.
Fix Duplicate Contacts by Checking Account Sync
Duplicate contacts often appear when the same person is saved under more than one account. By limiting which accounts sync contacts, you can remove duplicates without deleting data.
Open Settings, and then tap Passwords and accounts.
Tap the account you use for contacts, and then tap Account sync.
Turn off Contacts for accounts you do not want syncing.
Merge Duplicate Contacts Using the Contacts App
The Contacts app can automatically detect and merge duplicates. This keeps one clean entry while combining numbers and details.
Open Contacts, and then tap Fix and manage.
Tap Merge duplicates, and then confirm the suggested merges.
Review the changes to make sure nothing important is removed.
Change Contact Display Settings
Sometimes duplicates are not real duplicates, but separate listings from different sources. Adjusting display options helps show only one version of each contact.
Open Contacts, and then tap the three dot menu.
Tap Customize view, and then select a single account to display.
Exit the menu and check if duplicates disappear.
Remove Contacts Stored on the SIM Card
SIM card contacts often overlap with cloud contacts. Removing them reduces clutter and prevents future duplicates.
Open Contacts, and then tap Fix and manage.
Tap SIM card contacts, and then move them to your Google account.
Delete the SIM contacts once the transfer is complete.
Restart the Phone After Changes
Restarting refreshes contact indexing and applies all sync changes properly. This step helps prevent old data from reappearing.
Swipe down from the top of the screen to open Quick Settings.
Tap the Power icon, and then tap Restart.
Wait for the phone to fully boot before checking Contacts again.
Duplicate contacts on the OnePlus 15 are usually caused by syncing conflicts, not broken software. Once you clean up accounts and merge entries, your contact list should stay neat and easy to manage.
FAQs
Why do duplicate contacts come back after I delete them?
This usually happens when syncing is still enabled on multiple accounts. The duplicates are re downloaded from another source after deletion.
Will merging contacts delete any phone numbers?
No. Merging combines details into one entry, including phone numbers, emails, and notes.
Is it better to store contacts on Google or the phone?
Using a Google account is recommended. It keeps contacts backed up and prevents duplicates when switching devices.
