is it possible to turn the touchscreen upside down, so the scratches are at the top?
Hi I have bought an LG G2 D802 from eBay for practically nothing. The only thing that was wrong with it is that the screen had been replaced by what I presume is a cheap Chinese copy and after the replacement the screen would seem to turn off randomly (particularly during calls) and could not easily be turned back on again. Otherwise the phone works fine. The only thing that doesn't work is the proximity sensor. However I presume that this is a result of the new screen. Having read around on several forums, it seems that the proximity sensor is extremely sensitive to things like screen protectors, which can obstruct, or limit or prevent the functionality of the proximity sensor entirely. I therefore concluded that the likely issue was because the proximity sensor is likely to only respond to light over a given number of polarities (dark infra-red, placed against face, something similar I presume, in daylight or bright light, nearer the blue end of the spectrum etc). This would simplify how the proximity sensor should work under a number of given scenarios.
In the end the workaround was simple. I simply opened the phone and disconnected the proximity sensor and placed a small piece of insulating tape over the sensors connectors so it couldn't inadvertently reconnected when I closed the phone. The phone is now 100% fully functional, minus the proximity sensor of course. It now just functions like any other normal smartphone. I am naturally more than pleased with this outcome, given what I paid for the phone, which itself is in otherwise mint condition.
However the question I have is that the reason the proximity sensor was included was to prevent accidental button presses when making or receiving a call, when for example the phone is pressed against one's face. However it strikes me that exactly the same functionality should be possible in software? What I am looking for then is an app that will either lock the screen (or turn it off) to prevent accidental button presses in this way while a call is in progress and that will disable itself as soon as a call is ended. I of course need to be able to easily disable it, either from the lock screen, or via the power button, so that for example when I dial an automated dialling service and they want me to press buttons to navigate their menu I can still do this.
There seems to be a few apps around that can do this, but my question is, which is the best? Which is likely to cause the fewest problems for what I want?
I have ordered a new proximity sensor from China in case the proximity sensor itself might be at fault, but really having read that this can cause several problems and is rather more 'gimmicky' than practical, I think a software solution would probably be better anyway.
it should be replace with same hardware sir to be able for your device able to control it.
So has anyone found a fix for this problem aside from replacing the sensor itself? Maybe a build.prop or by using terminal. My phone screen wont stay on because it detects its in my pocket all the time posted screens below of useful info.

If you don't have the patience to read my story, skip to the solution at the end
Guys (and girls)!, I have found the solution, it took me like 6 hours to figure this out.
I have LS980 (LG G2 ofcourse).
I replaced the screen, and I actually refurbished the screen with LOCA glue myself, it is perfect, but apparently there's an issue with the proximity sensor, due to the specific shade they use to cover the inside of the glass at the location of the proximity sensor.
After replacing the screen, the Knock ON was not working, but KNOCK OFF was working fine.
In the Sensor Box i saw that i was getting half of the light that i was supposed to (on another LS980 i was getting about 800, while on the "faulty" one i was getting 400 light.)
And also the proximity sensor was dead, it showed 0.0 and a fallen plant.
I tried putting some tape, and colored it with a permanent market between the proximity sensor and the glass, and the KNOCK ON began to work, but during calls, the screen would not shut off.
I figured, there must be some SYNC between the light the screen is getting, and the proximity sensor, so i scraped off the paint that was on the glass where the proximity sensor is, so there will be much light coming in, and IT WORKED!!
SOLUTION:
Scrape off the dark paint on the glass (inside) at the location of the proximity sensor. do it gently.
clean it with alcohol so there will be no remains of paint.
don't be shy to press the Thanks button if this worked
Thank you work great

Use the thanks button! :fingers-crossed:
I just got my screen replaced, and this is happening to me. Is this something I can do myself?
My Fix
I apologize for bad english. If anyone knows SERBIAN and want to translate beter contact me.
Before you start to scrach the touch, try this.
On LG D-802 , the ruber thing on the proximity sensor was cousing me promblems. CUT the ruber only the part atached on the light sensor and proximity and turn it around. The big hole that was once on the light sensor(Ruber) comes on the proximity...
And that fixed my proximity. Now the light sensor is covered with the small hole on the ruber and the small amount of light is passing try that hole, try spreading it with heated something.
If questions PM me.
I think I am having the same problems with a G2. The digitizer on my girlfriend's phone broke so I replaced it with a digitizer/screen combo. No we can only turn the screen on (power button or knock) when there is a lot of light in the room. If it is dark, the screen will turn on for a second and then turn off. The screen doesn't go dark during a call either.
This problem didn't start until I installed the new screen. I scraped half the paint off but it didn't seem to make a different. I also don't have the screen completely sealed as I didn't have tape pre-cut for the shape of the phone. I wouldn't think that makes a difference but who knows.
Since I am a newbie in this technology, what is a proximity sensor and what is it used for when it detects or does not detect something?.. I installed the proximity sensor finder app on my Nexus 6 and I could not tell any details except timer started when portion of phone front was covered YET the measurement displayed did not say anything other than 0 or 5.00000 etc.. I also use the phone in speaker mode ..
The proximity sensor is there to turn the screen off during a phone call when you move the phone to your head. It turns the screen back on when you move it away from your head after. On the 6P it is located below the speaker grill.
Thank you,, so the proximity sensor serves a power saving function? I just tested this with my Nexus 6 using a TruShield TGSP and it worked fine.. I find it strange that a clear glass screen protector would not work on the Nexus 6P ??

No, the purpose of it is to deactivate the screen when it's against your face on a call so that you don't press things on the screen with your ear/face.
Yes, it does save a little power (you can power off the screen while on a call), but is really helps the screen know when you have the phone to your face. This allows it to disable input so you don't hit buttons on the screen while on a call.
It's a neat feature, but adds some difficulty because not all screen protectors are cut out to allow it to function fully. Like those above said, it helps you by not pressing buttons while you're talking.
I would also assume that android uses the proximity sensor for "on body detection" to tell if it's in your pocket or out in the open etc.
I am having similar sort of issue, I have glass protector on nexus 6P and when I dial any number the screen will go black and will not come back until the other person hangs up. even the phone is not near my face, how strange. not sure how to resolve
I also have a problem of my screen not turning on if I move it away from my face. At first I thought it was proximity sensor dead, but I used the proximity sensor finder app and was able to see that it works fine if I cover it. So it could be a bug with dialer/caller app in Marshmallow. Or maybe there's a setting somewhere.
How to turn off the proximity sensor? I have a tgsp that does not have a cut out for the sensor.
Return the tgsp because it's defective. The newer revisions do not suffer from the defect.

My screen does not go dark when I put my 6P by my ear. How can I check if my sensor is on or off? TThanks
My galaxy s6's capacitive keys have stopped working. It was a gradually process. At first they became unresponsive and then completely died. The light doesn't work either. I have tested the lights with the app galaxy buttons 2 and set the lights to be always on, but they don't even turn on by doing that. I do not know if it has been dropped as I bought it from a seller on ebay. Although he did say the rear glass has been replaced as it broke so I assume it has been dropped. If anyone knows what i need to replace in the phone for capacitive buttons please say. Thanks
Could be the magnetic sensor. Is your compass working? Do you have an original flip cover available? I had issue with my S6 when the phone completely hanged when using flip cover due to the magnets in the cover. My capacitive buttons worked, but no light. It was a warranty case, and the dealer said it's a magnetic sensor failure.
Hello guys im having an issue if i accidentally cover the front Proximity sensor the screen goes black if i remove my finger or hand screen comes back like im making a phone call !! And thats on the main home screen
