Ok so last night, pre is working fine, no problems. I go to bed, lay the pre there on the table, nothing happens too it.

this morning, normal speaker doesn't work, i can call people and i get nothing out of it, but when i turn on the speaker it does work.

Ok phone calls and text notifications (other things like charging it doesnt make a sound) make sounds out of the speaker, however there is no swooshing noise when i swipe a card, and there is no sound when i try to play radio/youtube or anything.

when i tried to make a normal call, i noticed the screen isn't turning off when i am calling someone and i have the phone next to my face.

...... no clue what happened here.
