Thanks for posting up your findings Breakd0wn. i am waiting on my ebay torx drivers to arrive before I rip into mine. i expected it to be a tension device on the stylus however the lock for the stylus is a tiny nub at the other end of the stylus slot so if the tension device is gone, the stylus will still be retained. i aim to fix my tension device - i'd noticed the friction had varied...sometimes a bit scratchy when sliding stylus in and out and other times normal.

I had the same problem after dropping mine from a small height. Afterwards the stylus would not go fully inside the slot.
I solved the problem by opening the battery cover and nudging that metal springboard with a pointy knife back into place. No disassembly required.
The stylus channel is relatively open to view except from some plastic arches so you can see where that thingy is and nudge it back.
I did it a couple of months ago and after a couple of more drops it is still in its place.

Righto, my torx drivers and leverage tools arrived so I got stuck into it today. Not such a hard job, the trickiest bit is getting the flex cable plugged in. I took some pictures:

In this pic look at the bottom right and you should see a tiny piece of curved metal. I think it should be stuck on with melted plastic, like how the stylus spring and that larger metal piece is. Now I've got the phone back together and am typing this I'm thinking I could have re-stuck the friction device with a dab of superglue.



Here is a picture with the friction device removed. The stylus is held in with that flat piece of metal running across - you can see the bent section at the pointy end - this clips into the stylus where there's a groove down near the pointy end.



The stylus is slightly looser now. I've actually taken the phone apart twice now - I took that friction device out and forgot I didn't have a photo with it in place so I put it back in. Took the photo and promply put the rest of the phone back together.... Next time around it only took a minute to take it apart so I may just try the superglue trick on it yet!

I just got this trouble, glad to see these reports. But chicken to take my phone apart while it's under warranty. Nor am I eager to go w/o my phone for weeks. I ended up forcing that gizmo out of the slot with an opened paperclip through those tiny slots in the channel you can get from only removing the back. Now my stylus is very loose. Yes it slightly clips into place at the end but easily shakes out. I tried a little tape but it quickly gets mangled. I actually don't recognize in the photos posted so far exactly where this thing fits. I'll eventually get over my fear of voiding warranty and open it up and see if I understand then. Until then, any clearer explanation and/or photos would be very welcome!

Happened to me too, wondering if any of the plastic that kept the spring there is broken.... trying to superglue it back on... What a medieval design....

So the subject of this thread happened to me twice in quick succession - once a little bit ago, when I just saw a little piece of metal coming out of my stylus slot a little bit into it. I preceded to sorta *push* it back into the stylus slot wall with the stylus. Then today it came out again, and after a little it of fiddling, something broke off, rattled a little bit, and then fell out - little bit of plastic, a little over a square millimeter in size.

Anyway, some metal rattled around in there for a while too - eventually I was able to prod things in with the stylus itself so that now the last two-three millimeters of stylus-into-slot insertion are really tight.

Not sure if it's the same piece that broke, but I was really happy to see this thread and know that it wasn't something major-concern-causing. (Phone still rebooted fine once during this process, but I wasn't quite certain it being okay was actually a long-term okay-ness.
