Chosen Solution
I have an Galaxy A51 5G (A516U) the phone was dropped and it broke the OLED screen. I replaced the screen with a refurbished OEM screen. Upon testing the phone I realized that the bottom loud speaker does not work. The earpiece works fine. I tried reboots, software updates, safemode, etc. Even did a factory reset. I ordered a replacement loudspeaker and it still did not work. Is this a software bug? Not sure if it stopped working before or after the screen replacement. Any help would be greatly appreciated.
Update (10/11/2022) Here is a picture of the speaker connection and other surrounding components does anything look out of the ordinary?
Check the loud speaker connections on the daughter board at the bottom of the phone. The two tiny spring connectors could of been damaged or locked out of line with the impact.
