I'm having a problem where in low-light areas, my screen turns off a second after I turn it on. The only way I can get it to stay on is by plugging the phone in or unplugging it if it's already plugged in. It seems like there's an issue with the light sensor / proximity sensor that helps keep the device off when it's in your pocket. I'd like to fix, disable, or remove this feature. Anyone else having this issue or know how to fix it? I've encountered it before with the lightflow app where the solution was to remove lightflow, but this is built in which makes it more difficult. Fyi My phone is rooted.

No suggestions for a fix, sorry. I saw behavior like this (screen turning off) when I put mine in an arm band case with clear plastic covering the whole front of the phone. I assume the proximity sensor thought the phone was in a pocket, etc.

The only thing I can think of to simply learn more about the problem is to install CPU-Z and look in the Sensors section to see what the LGE Proximity sensor is reading.

A screen protector that covers the sensors can also cause this.

I get this in low light, too. I have to point it at a light source to get it to turn on. Very aggravating. The longer I use my G4, the more flaws I find.

Do you guys have a tempered glass screen protector on? I have this too, and confirmed this is what it's from. When I had one that didn't directly cover the sensor I had zero issue. It may also be that the sensor isn't that great or polls on too slow of an interval.

Interesting. Does this happen in no-light situations as well? Or is there is a "dead zone" between normal light, and pitch dark?

I tried mine in an almost-fully-dark scenario, in a closet with the door almost fully closed. It turned on normally using both the power button, and double-tapping the screen. Mine is a Verizon model, 610B software.

Thanks @RedOCtobyr for pointing out it could be the screen protector

Yes! I have the tempered glass screen protector. I'm going to remove it now. Besides this whole light sensor issue, I absolutely hate this thing. Compared to a plastic screen protector, I can barely move/drag my finger across the screen because it grips my finger so much. I also feel like it messes up the touch sensitivity so that a lot of lighter touches don't register. Whether that's true or not, the excessive grip this thing has on my fingers and this whole sensor issue is reason enough to tear this piece of crap off.

...

Yep. Light sensor now works in low-light situations but detects when it's being blocked in close proximity. :) It feels a lot better to touch the screen now as well. Anybody know of a good plastic screen protector to order off Amazon?

I love my tempered glass. Just not ones that cover that silly sensor. I can't say for sure but I feel my G3 glass also covered it without this issue, or at least from what I remember.

Follow steps below to re-calibrate proximity sensor(must with the glass protector is installed and which is sensor covered up)

1. TYPE "277634#*#" in phone dialer. Hidden Menu screen will show up.*

2. Select "Device Test"->"MT", it will show "system will be restarted", then choose OK.*

3. After reboot, GENESIS MiniOS 3.1 screen will show up, press "individual item+power" while power button is pressed.*

4. Next, find "sensor test", enter it(do not block the proximity sensor), the proximity sensor will be automatically calibrated. Then block proximity sensor two times to exit.*

5. Find "Back to the MainList", enter.*
6. Press "Normal boot+power" while power butten is pressed to reboot system, done.

Now the problem should be solved.

Thank you for this. Although on Marshmallow the Hidden menu code has changed. I found this on reddit which helped.

"It is *#546368#*MODELNUMBER#
So for the international version it is *#546368#*815#
For the Dual sim version it is *#546368#*818#
I assume for the NA version it is *#546368#*811#"

I will see if it makes a difference. Cheers
