Replaced Batt & Damaged Scrn; Replaced Scrn & Damaged Mic(s). Help.

Glad I fixed my battery. Sad I damaged my screen while doing it. Glad I fixed my screen. Sad that anyone calling me now hears every other word and I sound like I’m in the bottom of a well. Concerned about opening the phone up again and breaking something else as I try to figure out mic(s) problem. Looks I have 4 mic openings: one on bottom on back. Two on bottom in front. One on top of phone opposite side of sims tray. I used glue to glue up the back top and bottom covers after fixing screen and battery. Thinking the glue covered or destroyed back bottom mic. Can I clean without opening phone again? Do I need to replace because it is damaged? I can’t find any replacement mic parts on line. Is this the end of the road for my moto-z? Help me save my phone if possible. Thanks.
