Hello, I just received Zenfone 9 today, and noticed that the microphone towards the bottom of the phone is not picking up any input while the microphone located at the top is. I tested this issue with the built in voice record app, a standard phone call, and the discord app. No matter what i do the bottom microphone just will not pickup any input. Is this a software issue or just a defective bottom microphone? Any help will be greatly appreciated. Thank you.
