Sage Kobo Sage periodically flips orientation during sleep

Cactus Chef · 01-10-2023, 04:54 PM

My Kobo Sage lives by my bedside desk, and it's usually the last thing I'm looking at before I turn in for the night. My routine is usually:

Read until sleepy
Press the power button on the back of the Sage to manually put the device to sleep
Put the Sage into its protective sleeve and rest it (face-up) on bedside desk.

Sometimes, when I pull the Sage out the next morning, the book cover of whatever I was reading is now inexplicably upside down. It goes away as soon as I power on the device.

I *do* have automatic rotation turned on (because I periodically switch which way I'm holding the device depending on where I'm sitting and which hand is holding a mug of coffee), and I have noticed that sometimes putting the device down flat makes it switch rotation, so, that much is fine. What I don't understand is how/why the device is switching screen orientation when it's supposed to be idle/off.

My Kobo is set to power off after 30 minutes of inactivity. When the Kobo decides to transition between "Screen off" to "Power off", is it also taking a split second to detect screen orientation at that time? That's the only thing I can think might be happening, but I can't imagine why.

My Libra sometimes is upside down when I use the sleep cover, because it takes a few seconds for the sleep cover to put it to sleep, so if I put it down at an angle, it can flip the book upside down and then go to sleep. I never see this when I use the power button, because I'm always holding the Libra upright when I press the button. I'm not sure how your Sage can flip the screen after you've put it to sleep already.

Heh. I never even remember which way my Kobos were supposed to be when I put them to sleep. I switch hands and rotation periodically, so the device can easily be "upside-down" when I start my next reading session.

Because the device doesn't go to sleep immediately (by design, and historical reasons, doing suspend properly on a lot of NTX boards requires *very* careful hand-holding so as not to crash and/or fail to suspend). Nickel *should* be ignoring non-critical input events during that transition period, but... apparently not ;o).

Even if it does that, orientation rights itself when you pick it up to read.
I'm not sure this is an issue worthy of much attention.

True, the impact is minor, but I'd still like to know why it happens.

The sleep cover on my Aura One I am sure causes page turns sometimes, so have to remember to always bookmark.

The Kobo is still responding to orientation a short while after you initiate sleep. May also be a delay in turning off front light. Hold in same angle for 5 or 10 s after closing cover or pressing sleep.
This is fairly repeatable, like if you tilt the instant the sleep image appears, then orientation is inverted later when you wake it.
