Samsung Google Nexus S - Delete all contacts
Delete all contacts
To delete all contacts, there a number of methods you might need to try. Note that the first two of these may be disabled on some networks/carriers, or Android versions.
1) Go to Settings - Applications - Manage Applications. Then chose All at the top. Then scroll down to Contacts Storage - B21Clear Data.
2) Go to Contacts. Then press Menu - Delete. Then press Select all (at the top) and then Delete again.
3) Go to Settings - Accounts and sync. Then untick Background data and Auto-sync. Then go to Gmail (or an account that your phone syncs with) and delete all of your Contacts from there. Then re-sync your phone.
4) Download an App called 'Delete All Contacts' and use that as a last resort.
These methods above will delete contacts from the Phone only, not the SIM card.
