I think it's Gotham.

+1 for Gotham, definitely.

I thought like you, but the apostrophe and the "serif" of the "y" do not match with Gotham.
Thanks anyway!.

Chris is right: it’s Gotham Light.

Go here, select Gotham Light and past this text “It’s not your dream phone” in the field. In brief, you have to use the correct apostrophe mark ’.

What you see as a “serif of the Y” is actually a kind of an optical illusion caused by the A/C vents (?) of the building.
