Front housing replacement for Gear S2

Hi there, about a year ago black bubbles started to consume the screen until I couldn’t see anything anymore. Is this a problem with the LCD screen? From what I could tell, the touchscreen was still responsive.

Also, I have been searching high and low for a front housing replacement part (I think this is what I need?) but have not found anything. Is anybody selling a cheap replacement part / knows where to find one?

Many thanks
