Okay. Thanks for the replies.

Apologies if the pics aren't enough, but they're the best I can do -- I don't have any device that can do a higher-res image than this very old Motorola phone. Because the stripe is really quite pale, when I pulled back enough to show the full width of the screen, it was close to invisible (certainly on the text pages). And the focus is crap, I know.

But to clarify: yes, the stripe remains constant, in exactly the same spot on every page turn; it's completely horizontal, and doesn't vary across the screen in thickness or angle; it goes from bezel to bezel; it doesn't vary with changes in light intensity, and is still visible if the light is turned off completely; and there's no break or lines within the stripe itself.

Yes, other than this mark on the display, the device still seems fully functional. All the menus/options still work. I tried upgrading the F/W to the very latest release, and that didn't fix the issue; I'll try a factory reset (can anyone point me please to tips on how to save annotations within files if I copy them across onto my PC?).

I haven't been holding it by just one side, or in a way that might twist the frame; I have very large hands, which is why I like the larger models, and typically hold it cradled in my palm with a thumb against one side of the case and my fingers against the other. So I'll check out the H2O (provided I can find a reseller with sample stock), but that's also why I'm drawn to the ONE -- a larger case is actually more comfortable for me. Since I'm in Australia, I would think my screen-replacement options are somewhat more limited than in Europe or North Am.

I've never opened the device. I can check the connectors, but I wouldn't really know how to look for them nor how to get in there. Anyone got a cheat-sheet, please?

I do appreciate your ideas. Thanks.
