[Q] How do I disable orientation-initiated screen sleep?
I'm not sure if I'm describing this correctly in the title so let me try and elaborate -
I've used probably 10-15 different ROMs for my Nexus 10 and lately every single one I try, I have the same issue when I have the screen titled down horizontally towards me while reading in bed ( think holding it up while lying on my back, angled down at me so I can read ), where the screen blacks out/goes to sleep.
Then I have to tilt it back so it's vertical again and sometimes it puts me at the lock screen but more often I have to hit the power button to get the lock screen back, infuriatingly I then sometimes get stuck in a loop of hitting power to get to lock screen as it's going back to lock screen so then it kills the display again so then I have to hit power again etc etc. Once the screen is back and displaying everything is fine until some random amount of time ( between 5 seconds & 5 minutes ) when the screen just goes black again - presumably when I move/adjust my position or the angle of the screen.
Anyway - I believe this is version independent, I don't think it's the ROMs, it's like it's something built-in to the OS.
The only thing I can figure is it's either related to the accelerometer detecting that I'm tilting the tablet horizontally so the screen is facing down and thus it is killing the display, OR it's the light sensor detecting a darkening of the light since I would be angling the screen away from a direct light source and so it kills the screen thinking I'm placing it face down on a table.
Possibly related - I've also noticed since 4.2.2 ( maybe coincidence ) that I can't rotate my screen 180 degrees and be able to unlock the device. No matter what, if I flip that sucker around it instantly kills the display and locks the screen. I've got auto-rotate on, so I know that's not the issue, and if I hit the power button to get the lock screen up, then unlock it INSTANTLY locks again and kills the screen. It's like there's a setting now that says I CAN rotate if I want to but there's no point because I can't actually unlock the screen to do anything. Keep in mind this ONLY happens when flipping it 180 - if it do it 90 or 270 and have it vertical there is no issue, it is literally only when it is flipped 180 that this occurs.
Am I over thinking this or is there something really, really obvious I'm missing? I've gone over every setting I can think of and the only thing remotely screen related is the sleep timer but it doesn't matter how long I make it or if I even turn it off entirely - every time I get into bed to read I have to mash the power button to get the screen going again. It's minor in the grand scheme of things but it is incredibly frustrating when all I want to do is read before going to sleep, just stay open damn it !
