Loudspeakers for OnePlus phones.
Weak or crackling sound from the bottom speaker is often caused by dust or water in the grille, so clean the mesh before replacing the module. OnePlus flagships have stereo speakers, with the earpiece as the second channel, so test both after repair. Match the speaker to the exact OnePlus model, as modules differ between generations and between flagship and Nord models. Use fresh adhesive when closing the phone to keep dust out of the speaker area.
Earpieces: earpiece.
OnePlus loudspeaker modules often include the antenna contacts, so install them carefully and check signal after the repair.
