Or the magnet in the cover is too strong!
I found that the craft "plastic" magnet sheets and strips that work on notice boards and can be cut up are too weak to operate any ereader, but that the magnet from a cheap earbud works OK. The covers have a skinny disc about 8mm or so diameter as the magnet. You can feel it on the inside if you press hard.
I'd be surprised if it's a user setting and it could be a fixed level in hardware using one of the GPIO SoC pins that either only does logic level on/off (based on maybe 3.3V supply) or a comparator rather than an ADC pin that reads a particular voltage. But I don't know how it's connected and tested. However you need a wake-up interrupt and that is far more likely to use a dumb on/off pin as I've never seen a controller or SoC CPU do Analogue to Digital conversion without waking first.
