Both iPhones and Android phones allow you to block phone numbers. You can add specific callers to your smartphone’s blocked contact list to prevent them from calling.
But what would happen after you factory reset your phone? Will your previous blocked callers will still be blocked or will they be able to call you again?
Does factory resetting unblock blocked contacts on your iPhone?
A factory reset will unblock the blocked contacts on your iPhone. Factory resetting deletes all user data including contacts and blocked contact lists on your iPhone. Therefore, your previous blocked callers will be able to call you again after the factory reset.
However, if you sync your contacts to iCloud, it will restore the blocked caller list when you sign in to iCloud after a factory reset. Therefore, with iCloud, your blocked callers will still be blocked and won’t be able to call you after the factory reset.
Does factory resetting unblock blocked contacts on your Android phone?
Just like with iPhones, a factory reset will unblock the blocked contacts on your Android phone. Factory resetting an Android Phone will delete all your contact lists and blocked caller lists. Therefore, your previous blocked callers will be able to call you again after you factory reset your Android Phone.
However, if your Android phone’s contacts are synced to your Google account, it will restore the blocked caller list when you sign into the Google account after a factory reset. So, with Google account syncing, your blocked numbers will still be blocked after you factory reset your Android phone.
Why do your previous blocked callers still call you after factory resetting your phone?
As we have said before, factory resetting your iPhone or Android phone will delete the blocked caller list. Therefore, your previous blocked callers will be able to call you again after you factory reset your smartphone.
However, if you sync your contacts data to iCloud or Google Cloud, it will automatically restore your blocked caller list after a factory reset. In that case, your previous blocked callers will not be able to call you again even after you factory reset your phone.

Conclusion
A factory reset will unblock blocked contacts on both iPhones and Android phones. Factory resetting erases locally stored blocked contact lists unblocking previously blocked callers.
