when i leave my g2 to sit with the lcd on , the soft keys and keyboard backlight cut back on when i wave my hand across the top , is this because of the light sensor ...
Yes, it's your hand blocking the light
im not making the light cut off thats my settings for it to go off if not used for a min. but if i was to wave my hand over it awakes the lights
...im not holding my hand over it at all just a wave of the hand
It's probably registering input from the proximity sensor. Just a guess.
Hey there,
I got one of those "smart" cases which send my Nexus 10 to sleep and wake it up once i close/open the front cover.
However i wondered how this really works, is there a sensor within the Nexus 10?
Also , i lately put my Nexus 10 the wrong way round(with the screen still facing me but the lower bottom, where the pogo connector is being up and the camera being down) in the case and closed the front. As expected the Screen didnt shut nor did it wake up when i opened it.
So i guess there is no sensor on that side of the tablet?Is it possible then to harm the hardware inside by the magnet withing the case. I mean when i put it in the wrong way round.
Thanks in advance for your help!

LOL. There is no wrong way! OK. There is. Don't drop it on a hard surface.
There are magnets in your case that trigger the wake up/down of your N10.
the magnetic sensor is right about the left side of the ambient light sensor... try running a fridge magnet there and see the screen go off and on when the magnet is away...
So a customer has informed me that they are having issues with their G2 after a screen replacement.
The issues are:
-Screen is blurry (obviously will need a new screen)
-Knock on isn't working.
-When she unlocks the phone it sometimes locks itself again.
-Screen does not wake back up when proximity sensor shuts it off during a call.
I am guessing that all of the issues are to do with the new screen.
Any help would be great.
Did you update the touch firmware for knock on? Maybe the proximity sensor not waking up has to do with the modem. Idk I'm a noob to these things but that's my opinion on what's wrong.
Was/is it a genuine LG screen?

No. It is not a genuine screen. It is an aftermarket screen. I've repaired hundreds and hundreds of phones with third party parts. Never had any issues like this.
the g2 is locked down tighter than apple products. i wouldn't be surprised if the aftermarket screen is a result of all those issues.

Do you have a more detailed reason behind the issues?
Still looking for some info.
it's the proximity sensor. I put a little piece of electricians tape on the pad that pushes the proximity sensor into the phone screen and that solved all my issues. Message me if you have any questions

I have the same problem. Could you please be more specific on the solution you found. Would a photo be too much to ask?
Many thanks!

Hi, I had lots of issues with my proximity sensor too, and I just fixed it. Most of the time the sensor would detect an obstacle at 0cm, preventing knock-on and knock-code, making it very hard to unlock the phone and keeping the screen black during/after calls.
My issue was actually a small pad behind the sensor, that's supposed to push it against the screen: that pad was too thin!
Adding some adhesive tape on that pad solved the issue for good! That pad is on the rear buttons assembly (the one that is hold with 7 screws).
More precision about how to fix:
- remove the rear door.
- remove the 7 screws holding the plastic assembly holding the rear button.
- remove the rear button assembly.
- loot at the rear of that button assembly: on the top left there's a small soft pad that's supposed to push the proximity sensor against the screen.
- add some thick adhesive tape on that pad
- put everything back together: put button assembly in place and clip it, put back 7 screws, clip back rear door.
Agree with the crowd, it's the prox sensor. Same thing happened to me when I replaced a screen recently. The tell tale sign is when making a call, the screen will turn off. This is because it's already sensing that the phone is being held up to the user's face when in fact it's a false positive. I believe there's one of two reasons:
1.) Following screen install, the prox sensor is located an incorrect distance from the small window it looks through. In other words its too close or too far away.
2.) The prox sensor is not correctly centered in the window it looks through and needs slightly tweaked up/down/left/right to be perfectly centered.
I couldn't determine beyond a doubt which one of the above was the case or perhaps both. But after taking it apart a few times and tweaking the position of the sensor, mine started working ok and has now been functional for a few months without issue.

Many thanks on the very detailed instructions. I will try them out tomorrow. What I have noticed though, is that I can see the LED through the proximity sensor window, so it might be a misalignment issue as well. Any suggestions on where to buy a new screen for the G2 ( preferably Aliexpress or ebay).
Hello XDA,
I think I discovered a weird feature or a bug when ever you place your S4 on top of a speaker. I have a portable Jam XT soeaker and when I place my phone on top of it, facing up the screen goes black only showing the tine and partial top bar.
Will attach screen shots.
Any Idea what I stumbled upon ?
Heres the screen, new account, sorry.

Go to imgur, fill the gap
The S4 has a magnetic sensor which works with the S-View cover.
The magnet in the speaker probably activates the sensor in the phone, thus the phone enters the S-View cover mode.
I recently bought a 6P (yey!), so far I've enjoyed it a lot! Came from a N4 that also served quite good.
Anyways, I bought a screen protector without the cutout for the proximity sensor. So as you would guess the screen goes black after I answer a call and it is really annoying.
Is there a way to disable the "darken the screen when a call is active" or another solution without replacing the screen protector?
So far I only enabled the Hang Up power button press feature, and I don't like this solution.
Thanks in advance
The only workaround (on stock) is to enable power button to end calls in accessibility options. My toast skin and TGSP was doing this to me until I got fed up and made the cutout wider - haven't had the issue since. If you download a proximity sensor tool or test suite from Play store you'll see that the phone can't detect distances - which is why it assumes it's pressed to your face.
