Like in title. I was changing back glass of my iphone 8 but after i assemble everything and turn phone on i realize that my loudspeaker is much quieter and i nearly can’t hear anyone when on free-hand mode. Any idea what may cause this?

Hi , There is not too much that can affect the speaker volume. Since the volume is working, but just low. It is most likely one of the following. Blocked airway at the speaker grill Damaged speaker Poor speaker to port flex cable connection I hope this helps
