Galaxy S21 ultra makes hollow sound when tap on back panel

[RonyRocks]

Hi fellow Member,

I was just wondering if any of you guys noticed the hollow sound when you tap the back panel of the s21 ultra. For me when I tap with my nail it makes a hollow sound as If there's some air gap under the panel. I just want to know whether it is a manufacturing defect or all 21 ultra makes the hollow sound. 

Thanks

It's not a manufacturing defect, they are all the same.

I own the S21 Ultra and sometimes same thing happens when I tap the front screen. This is nothing to worry about.
