OPO Headphone jack problems

Hey, i have two questions and you guys seem to know alot.

#1 My headphone jacked is kind of wobly. When my headphones gets

pushed to the side they loose the contact and the music stops, but on

the screen it sais that the headphones still are connected. When i

push the headphones back to the same spot the music jumps back and

plays again. what could that be for problem do you think?

#2 if the headphone jack is worn out i am thinking o changing the

component and i wonder if there is any phone with the same headphone

jack so i know what phone i can buy spareparts for.

I have asked oneplus but they where to no service at all.
