For me, it's not "very slight", Geoff -- almost every time it doesn't happen at all.

In contrast to the posts that say "it doesn't happen on my device" (thereby strongly implying that it must not happen on anyone else's either, or that people are making something out of nothing), I think it's interesting that I spoke to Kobo Customer Care last night, and the operative I spoke with took the time to test the long press on test devices they had in the centre for just such purposes. He tried it on two Aura HDs, both running 3.15. One had no issues with long presses, and the other consistently reproduced the issue I was raising: that long presses produced no response at all. He did mention that the one where long presses worked was an N905C, and the one where they didn't work was an N905B (which mine also is), though they were unwilling to state that that was the reason for the different result. (Fair enough, I think.) The incident has been escalated, as they could reproduce it, and I was told they took it seriously enough that they are willing to replace my device over this even though it's out of warranty. (I'm reluctant to do that, because I don't believe it's faulty hardware -- I didn't have this problem under any of the last few firmwares, and I know Kobo tends to take a bit of a hit-and-a-hope approach to replacing hardware as a way of trying to resolve issues.)

I'm in the process -- as i agreed to do -- of doing a full factory reset of my HD, and re-installation of the new firmware and, of course, my Library and my collections, and see how it behaves. (Massive pain, thinking of trying to load books back into the Collections, if the long press isn't going to work!)

I was never suggesting that everyone had the same problem, only asking if other people did. But I'm glad to see that Kobo, at least, can reproduce the issue.
