People still can’t hear me when I call. However, if I switch to loudspeaker they can. Did I miss a connection or do I need another part?

The repair went smooth!It took me roughly 30min. Like the instruction say, use heat for the glue so you do not damage the sensitive instruments. Everything else will go smooth. Like always, good step-by-step instruction, good replacement parts, and tools. Thank you iFixit. Keep this business model and I will be a loyal customer as long as repairs are needed. Actually one complaint, I never get a free sticker for my laptop : ( Its good advertisement…hahaha.
