[squiresque]

Since I otherwise find the Kobo Forma amply featured (subject to further investigation of the pulse width modulation issue discussed in other threads), I am guardedly grateful that Customer Service has apparently identified a remedy to the wedge side lighting abnormality. (The abnormality is most noticeable and disturbing when viewing a PDF in landscape mode since in that mode the barest-of-bare-bones Kobo PDF software makes use of the defectively lit region for actual text.)

I would be grateful if, before redoing all of the work already done to setup the Forma, some explanation would be provided by Kobo as to why a factory reset is needed, and, further, whether further factory resets to correct the issue or ameliorate it, will be required going forward.

Surely the device was in a factory-reset state when I purchased it. If such a reset restores the lighting to a nondefective state, then ordinary customer use for a rather brief period of time was sufficient to undo whatever benefit the factory reset accomplished in the first instance. Thus, it can be expected that further customer use will soon result in a repeat of the light irregularity, and, if the current recommendation is sound, a need for yet more resets, ad infinitum, ad nauseum.

I cannot count the times when a technical support person - well-intentioned as ever - has responded to a technical issue by recommending that I go through a series of lengthy steps, full of sound, fury, and resets, but solving nothing.

Having said that, I do hope the issue is resolved as there is much to like about the Forma.
