Wow. It looks as if it's partially under the shield, bending it

That's what you get for taking your Neo with you on those
teleportation experiments. Have you learned nothing from "The
Fly" ? ;-)

The round pad has a diameter of 1.6 mm, so the component appears
to be 1206. That's mighty big for a resistor. It could be an
inductor, but then it would seem a little flat for that. I can
only find two 1206 components in the BOM, and they're both
AFAIK it's a factory rework on A5 to implement some fix. I didn't check what
it is exactly, but afaik it looks like some pulldown to GND (= can metal).
You can tell easily by finding out about the testpoint it's soldered to.
Anyway I've seen that on many devices and it's ok (no fault or misplaced
Absolutely right. It's R4411, a 100k pulldown from H-TP4402, which is the
RX_IRDA signal used for GSM firmware download at the factory. Page seven of
the GTA02 schematics lists R4411 as NC for GTA02A5 and 100k for GTA02A6.
Thanks for clearing it up.
