how to delete all contacts at once?
 

i decided to install openmode to use nitdroid and backup menu, so i deleted all my accounts. the contacts remain in the phone. i don't know why, but i didn't managed to install nitdroid nor backupmenu this time (i've used nitdroid before) so i decided to resync with all my accounts. now i have all my contacts duplicated. is there a way to delete all contacts in one time? not one by one

Open Contacts App->right context menu click Delete Contacts

Then choose Mark All in the window that appears and click delete...The window will disappear and a confirmation to delete all contacts might take 5-10seconds to appear if you have >1000 contacts...
