Yup.. same here.
Fluctuating/inconsistent volume for keyboard clicks\lock sound\camera shutter on my Iphone 11 Pro Max IOS 13.3.
It's very frustrating.I tried absolutely everything and nothing works.Beside the temporary fix mentioned here of course but i want a permanent fix. I did my part.. i called apple and told them about it, i gave them feedback of the problem on the apple website and i'm posting here asswell just maybe apple notices that loads of people have this problem.
i'm paying to much money for your overpriced piece of **** to have to deal with these kind of bugs.Samsung galaxy note 10 starts to look better and better with every frustrating bug i come across form this PRO, TOP OF THE RANGE, REALLY EXPENSIVE DEVICE!
