Since I had it, I've wanted to address the floppy hinge and sharp edges on it, but apart from fitting the camera, memory card and SIM when I first got it, I'd not taken the covers off my G.
Last night I needed to swap the SIM out, and I took the cover off and cleaned out the small amount of dust. I looked carefully at the hinge cover/spring and found it was really easy to pop it off with the phone open just over 90 degrees.
I realised that what we've been calling the hinge is actually the hinge cover and spring. My spring was so floppy it made almost no difference when removed!
Using a fine file, I de-burred the edges of the camera cover and hinge cover edges (literally a few strokes), bent the spring to nearly 90 degrees and refitted it - it just pops back on. Just be sure to wipe off all filings carefully of course!
Wow, what a difference. It's so much better, the screen doesn't wobble as I type, and doesn't shift much as I touch it. Before it wasn't very nice trying to use it entirely hand-held, but now that's feasible.
So if you haven't done this and your screen is all floppy, I highly recommend it. Takes about 10 minutes all in all, even including the filing the edges smooth.
