I'm wondering if this is a hardware issue. Given it's already been replaced by Amazon, this could hardly be.

No, just the opposite.
All of Amazon and their refurbishment contractors use the same test and quality assurance software.
Something that is missed (or adjusted improperly) by that software for one will do the same for all, regardless of the number of times run.

Probably a good idea.
Too bad they don't give bug killer awards.

OK, deep breath, see if I can get the mind into system designer mode ...
Both the KOA2 and the PW4 have the "Androidized" system.
Where all other (firmware) series 5.x devices have been dual boot, these are better described as "dual mode".
They do not have a separate, storage backed, "Diags" system.
And, the KOA2 came first.
The initial, ram resident, system of the prior devices was often called the "Recovery System" by Amazon/Lab126.
What had been the functions of the storage backed "Diags" system has been moved into the initial fs "Recovery System".
Anyone who thinks the 512M memory size was a gift to the customer, please raise your hands.
Everyone with their hand raised, please stand in the hall and keep a look-out for
No, the 512M memory size is so the initial ram resident system can be large enough to run the "Diags" functions (even so, probably trimmed down a lot).
The TS registration (i.e: alignment with display) needed different parameters for the KOA2 (different screen dimensions).
When the PW4 was engineered, they forgot to put the parameters for the smaller dimension screen back into the calibration/registration diagnostic.
(People do not mess with the code, once working, in the initramFS system.)
End result:
The touchscreen reports a different than actual finger position at the right boarder of the display.
(With the same at the bottom of the display, which is rarely used. We have already had a few reports of the reading position display in the lowest left corner not working properly (can not select location display type) ).
Report to Amazon is:
"The touchscreen calibration routine for the PW4 is, incorrectly, using the KOA2 calibration parameters."
With the result: <describe here what you have found>
That should be worth a $25 bug killer award.
