How to dial contact which space between name

[wluczykij]

To call to jakub  i open call app And dial 52582

So I get. A list of contacts with Jakub in the name.

But sometimes there is to much results. So I want to add second name. But I cant do that becouse dialer dont have a "space symbol" and first letter after name clear a list. Is there a solution.?

No, there is - as you said - no way of getting a blank space in the dialer.

Your option is probably to go either with contacts search instead (you really doesn't loose many seconds by using that one instead of the dialer, it's in the tab next to dialer.

You could also use Bixby or Google Assistant by just saying "Call Jakub Nowak", "Call Anna Kowalska" or whatever contact you're looking for. Good to know is also that you actually can assign nicknames and relations in your address book, so for instance I have "Call my wife" or "Call my mother in law" instead of searching in the favourite contacts list.

If you start with the dialer, it only handles numbers and will suggest names from your contacts based on which numbers you type. If you want to go on names, I also suggest you switch to contacts and search there.
If you have many duplicates, the contacts app can fix that and merge them.
