Is it so hard to implement a block/unbock option on numbers? In option i get option to block a contact, but i when i block and call them again, i don't get option to unblock on that number, but again to block them. I have to go to settings blocked number to unblock a person. Please fix it. If (Person in block) Show unblock option Else show Block Here a simple code for your engineers. Why are you paying such engineers when they can't implement such a simple feature. Please test your app.
