iPhone 6(S)/Plus iPhone 6 Phone Call Volume Problem

[krawfo]

I’m having a problem hearing phone conversations on my iPhone 6. I have the volume maximized but can barely hear the caller. If I switch to speaker the volume is normal.
I’ve turned on Hearing Aid Compatibly and turned off Noise Cancellation. I also cleaned the ear piece with a dab of alcohol and gently brushed with a soft brush.
I’ve Any ideas on how to troubleshoot this problem ?

Try to clean the ears speaker grill with alcohol and cloth.
Had this once on a 6s. I replaced before the inside speaker without effect.
