Answer to: top speaker not working what do I need to doI had this problem for months. Annoying and frustrating. Top speaker audio returned sporadically last week then stopped again. I had already checked for software conflicts and cleaned all the grills/ports with a toothbrush. Today I noticed one side of the phone looked slightly deformed. I held the phone by the corners and gently "twisted" so that the pressure was being exerted in the upper left corner (opposite the light and camera) and the top speaker came roaring back to life. Probably a loose contact but I was able to fix it without disassembly. Good luck.
