My S6 stopped outputting sound on the loudspeaker. No rings, notifications, media, nothing. I ordered a replacement part and installed it, and still have no sound. Now what?
Can you check if the phone is stuck in headphone mode? The volume sliders shown when you press volume up and down should be at different volumes when you unplug plug in headphones.
Naar the speaker contacts on the mainboard you have two bronze coils check they are still there and haven’t been knocked off or came off one solder pad. If they are there replace Audio amplifier which is second biggest IC on bottom back of mainboard. You can also run speaker calibration if you have access to Samsung software
