How to delete all contacts
There are a number of ways, as below. The first two of these may be disabled on some networks/carriers or Android versions however.
1) Go to Settings – Apps. Then scroll down to Contacts Storage – Clear Data. This option may not be available on all models.
2) Go to Contacts. Then hold and press on a contact. Then choose the All option at the top of the screen and select Delete. .
3) Go to Settings – Cloud and accounts – Accounts.
Then scroll down and select Google.
Next, change the slider so that Sync Contacts is disabled.
Then go to Gmail 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.
The methods above will delete contacts from the Phone only, not the SIM card.
