Chosen Solution

L.S. I have been battling with my 6S since day one, now the situation is the following: the load speaker is mute the vibration doesn’t work the jack is mute the battery doesn’t charge all of it unless i keep some pressure on the phone, as if there would be a loose connection in it. I would love to open it up, but i would prefer to know upfront if i need parts. As said, it all runs ONLY IF i keep it pressed. Any advice aside the trash can?

I would suspect the charging port assembly may be at fault as it provides connections to all of those parts. Note that it might just be the charging ribbon cable just needs to be replugged to logic board. Also check if the charging port assembly screws are all there.
