Distortion on earpiece after replacing screen

I’ve recently replaced a broken screen on my iPhone SE (2016), the replacement is not an official iPhone screen but from an observational point of view and according to the website, it is of high quality.

However, ever since I installed it, the earpiece of my phone sounds distorted, not only to myself but also to whoever I am on the phone to, which makes me think that the distortion is affecting my phones noice cancellation.

I suspect that when I re-attached the earpiece I may have fixed the screws too tightly, and in doing so, preventing the small springs that are attached to the earpiece from absorbing enough vibration to prevent the distortion.

Any thoughts over what can cause this problem would be very much appreciated, thanks.
