Tiny little electronic component came out of my Kindle...

I actually have a Kindle Paperwhite 8^th Generation but that wasn’t in the list.

I figure that any site with a Teardown section has the readers to help me so here it goes.

One day the touchscreen just stopped working.  I can still charge, I can turn it on and off, but when the “Swipe to Unlock Kindle” appears, swiping does nothing.   It’s on an ad so the “Read Now” does nothing either.

I can reset with the 40 second holding of the button and that brings me to the Home screen but again, not responsive to touching anything.

I also noticed a very quiet rattle of something inside when I move the Kindle from side to side.

I called Amazon and they basically said they’d only credit me $15 for the device so I figured I’d try and open it and see if the rattle was anything.

I managed to get a corner open, and directed the “rattle” to that corner. A tiny white component came out.

I opened the device further to see that the screen was surrounded by these and one was missing.

What are these?  Is this the cause of the touchscreen not working? Is it worth trying to solder it back on?  If a mini resister or capacitor, can I replace with a larger one of the same value?  Any help appreciated.

First image shows the internal board. As you can see, the 5th component on the top from the left is missing. The second image is face-up and the best close-up I could do. The component contacts appear to be on the sides.
