Call Screen Stays Black - LG Velvet Questions & Answers

So when I make a call on speaker phone, the screen goes black. I have to hit the power button to wake it up.
Is this supposed to happen?
Is there a way to keep it from going to black screen?

Just tested that out and it happened to me as well. Do you have the tempered screen protector on?

No screen protector, just a case. So I took off the case and just for fun, I cleaned the top of the device. Ear piece, front camera and all the glass.....low and behold, it now works as it should. Guess the proximity sensor was dirty. :victory:

I just took my screen protector off and no more problems either.

No a screen protector is transparant, so it will let all light go trough.
Don't be afraid it will still work.
Try calling anyone, hold u phone near ur head, the screen will go off, and after, it will go on again
The proximity sensor does not depend on light to work though, try your phone in complete darkness and you're proximity sensor will still work.
no mine has worked perfectly with a screen protector since i have got the phone
Thanks for all the reply!!
It was very hard finding SP that covers the whole screen but with a small opening on the upper left for the sensor.. now I'll just get those that covers the whole screen

Don't buy ElecShield screen protectors

Don't buy these

They break the proximity sensor (phone thinks it's near your head all the time). This is my experience, YMMV.
I guess you could cut a hole but it's bit of a PITA.
Mine are already on the way. What's the fit like excluding this problem?

They're a little on the small side but not too bad, I had mine fitted perfectly and it covers only the actual live area of the screen width wise, and is a little short of the top and bottom of the glass height wise, maybe 2 or 3mm.
I just did a little testing of the proximity sensor with my hand, without the protector on, and it seems that the proximity sensor only turns the screen off when the phone is vertical not when laying flat. Might test some more with the protector. I had to rip it off to end a call earlier!
Just done a bit more testing and indeed, hold the phone vertical while on a call and put the screen protector on, screen turns off, take it away, screen turns on. When the phone is flat the proximity sensor does nothing so if you put the phone flat while in a call you can access the keypad etc.
SGP ultra clear blocks the proximity sensor too

I spoke to an SGP UK agent on Tuesday. He said SGP are revising their design to allow for this. Said should have the new version sometime next week.
I have some cheap screen protectors that used to cover my SGS2 proximity sensors and had no problems, guess I'll report back when I get my phone ):
I have a BSE on order. I hope that doesn't do it :'(

If any protectors do cover it, a hole puncher should take care of it pretty easily. It may not result in the prettiest results, but it will get the job done until all of the manufacturers revise their designs to not cover it.
That works well enough for now

I bought from same seller in ebay, not a good fit (very short) and have proximity sensor issue as well.

Like it has a screen protector not properly fitted

Hey
I took off the plastoc cover that had about the screen and NFC features.
But to the left of the speaker (Not the screen, hust before the phone curves) it looks like when you put a screen protector on and its not pushed down enough. It looks lights than the rest of the phone.
Anyone else got that

Proximity Sensor for Newbies

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

Screen won't turn on, thus stays black during call.

Hey, when i receive and accept a call, my screen immediately turns off. Like it should when i put my ear up to it. But during the call i cant do anything to get the screen to turn on. After the call i have to press the lock button and unlock it again to get it on.
1) bootloader unlocked
2) custom kernel?
3) stock ROM?
4) rooted?
6) What version of the OS are you on? MM 6.0.1 / .511
7) This is recent, tried with 2 different roms so it isnt rom reliant i guess.
8) When in service menu and testing the light sensor it responds on my hand covering the sensor so i don't think its faulty.

Clean your screen protector, if you have plastic protector REMOVE the screen protector.
Flash FTF with all WIPE options selected..

Mostly, screen protector cause that. Second sensors might be broken. Software is the last thing (if comes with stock)..
Go to *#*#7378423#*#* service test and go to proximity sensor, if it stays "ON" something is wrong with the proximity sensor, if you are absolutely 100% sure nothing is blocking your sensor, have you ever changed your display assembly? try pressing down around the top right of screen with a little force, both front and back if it switched to "OFF" when you press your screen there's a slight gap between your motherboard and front glass.

Holy this is it. I had to get my front glass replaced because it was shattered, when i press the screen it turns off, when i block the sensor it goes back to on again until i press on the screen. Also my vibrator motor seems to not function properly since, it sometimes doesnt vibrate at all, and sometimes with very little feedback. Could this also be a result of the replacement?

It could be the glue is not settling in correctly and adds very little gap than original one, did you replace the screen yourself? Mine showed this behavior I then reheat the edges of the screen with hair dryer then put pressure around the screen with those black paper clips, reheat it again then let it cool for about 2 hours.
I'm not entirely sure about the vibrator motor

No, I had it done by a company in phone repairs. But i kinda regret fixing it instead of buying a new phone tbh..

I bought this phone second hand and it had this issue, What I did was hair dryer and paperclip. and ..... try a more ghetto solution, which involves opening the back door, put some foam and double tape it near the camera module, there's an empty space. Make sure it presses the motherboard but not too hard or it will compromise the waterproof glue holding the back cover.
