I received a Nokia Numia 635 (T-Mobile) yesterday for my birthday. I've since noticed that when I try to use headphones with it, the phone doesn't "detect" them, i.e., it keeps using the speakers. I'm using a pair of Skullcandy Hesh 2 headphones. Is there anything I can do?
I just found the solution - A simple restart fixed it.
EDIT: The phone was brand new when I posted this, and I'm going with the assumption that it had something to do with the updates needing a restart to finalize.
