How would you do screen replacement? That is a common repair since people drop their phones and currently you can get your phone repaired by some teenager in a booth at the mall. If you fill the phone with epoxy, how are you detaching the screen, and getting a new ribbon cable through the epoxy?

Just like they do it today - a lot of grinding, swearing and overall understanding what the civilization is going in not quite the right direction.

use pogo pins or a board to board connector

Which means air space that can get crushed. Either the phone is solid or it isn't.

Would note that air isn't the only substance in a phone that compresses under 38 MPa. (Batteries come to mind.)

Air is the only substance that compresses to any significant amount. When you apply pressure to a battery from one side it may deform, but I would expect that the battery wouldn't be crushed because the pressure is from all sides - unless of course there is air in the battery - I'm not a battery chemist so take everything I say with some salt.

Note that I would expect water to seep into a battery at this pressure and that will cause all kinds of issues - including chemical fires underwater. Just not crushed batteries.

So what if you can't replace a screen on an epoxy-filled cell phone? That's a small price to pay for knowing that your camera will survive if you take a one-way trip to crush-depth.

Is this sarcasm? 99.999% people will never take it beyond a meter in a pool.

Poe's Law never fails. I should have accounted for that.
