No sound from Top Earpiece speaker after screen replacement
My Niece dropped and broke Lg g3 digitizer. I replaced it with lcd and digitizer with frame. One thing I didn't install is tiny daughter board all the way in bottom.
After powering on phone, I can not hear anyone from my top earpiece speaker but clearly hear them from when I transfer call to speaker.
Is daughter board needed and what's it's functionality? Top earpiece in anyway connected to daughter board?
One more thing I also lost about 3 screws and looking up online only source looks like ebay at $10.00. I can't justify paying that much for tiny screws. Any leads on replacement for them?
