Disable kindle cover events turns itself OFF

[Commodore64user]

• KOReader version: Sourdough (this happens in previous versions too)
• Device: kindle voyage

Issue

Disable kindle cover events won't survive firmware updates or device restarts. It turns itself off.

Steps to reproduce

Toggle ON the option by going to “cog > device > disable kindle cover events” now press and hold the power button for 40 ish seconds (or update the firmware) wait for kindle to re start itself, launch kOReader once more and go back to “cog > device > disable kindle cover events”, now the option should be turned off (well technically it shouldn't but you get my drift).

Hey @hius07, could you check if your kindle does the same. Sorry i don't know anyone else with kindles here.

Yep, same behavior on my Kindle Paperwhite.

[hius07]

It's not a KOReader but Kindle system setting (the Hall sensor), rebooting resets it.

But couldn't koreader reapply it on start?

[hius07]

Sure it can, nobody requested the feature.

Lines 192 to 195 in 2f0e456

	function KindlePowerD:onToggleHallSensor()
	local stat = self:isHallSensorEnabled()
	ffiUtil.writeToSysfs(stat and 0 or 1, self.hall_file)
	end

I solemnly and officially request said feature.
