Black screen - G2 Q&A, Help & Troubleshooting

I broke my phone and just received a new one from the Geek Squad. Two things. When I make a phone call the screen immediately goes black and won't come back on until I push the on button on the back. Really sucks, hard to end call. Also when it times out I have a really hard time getting the screen to light up again. Some times it takes 8 to 10 times pushing the on button and swiping the screen. Any ideas?

I would go back and Tell them to fix it. Did they repair your screen? It is possible that the proximity scanner was not plugged in properly or out of its slot.

Screen stays off throughout the call.

Hey friends,
I am facing this problem while making calls that as soon as I press call button or receive button(while taking call) the screen turns off n stay that way till the call ends.
I have tried pressing all hardware buttons,even moved the dvp awayfrom me n into direct light but to no avial.though it did turn on once or twice out of twenty times.
Did anyone else experience this? Any suggestions are welcome..

Do you have a screen protector or case that is obscuring the light sensor or proximity sensor? My first guess is that something is obscuring one or both, because during a call the screen being off is a feature.

screen stays black/off during call
The screen stays black during a call and this happens ramdomly. I have a dell venue pro a t mobile phone but it is a pre release so it works on att 3g and all. I have switched the sd card with no improvement. I have ordered a transender 32 gb sd that I haven't received yet. The firmware version 2250.1400.7004.025 hardware is 112.576.2.0 radio soft 2.2.50.14 radio hard 8250. I have been unable to get any of the hardware keys to hang up the phone which if I get voicemail or something means I have to power the phone down to get the dang thing to hang up. Sometimes it works fine but I cant find a commonality software or hardware that causes this. It happens right out of the box so even after a software reset it can happen. Is there any solution for this issue?
I can't understand why the button on top doesn't hang it up.
PS I got this phone for free and I got ripped off LOL
wow just got a replacement phone today and im having this problem, As soon as I go to make a call the screen goes black and cant do anything on screen during the call, so i cant enter my password when checking voicemail
I think it's related to the proximity sensor. When you put the phone close to your head, the screen switches off. When you move it away, it will switch on - most of the time .
If it stays black, have you tried tapping the power button on the top of the phone? It switches the screen on without disconnecting your call.
A coworker got a replacement the other day(they send a refurb) phone and it had the same problem. Had to go through Twitter to get Dell to send him a new retail phone since they had send him 3 refurbs prior and they all had different issues.
This is just a general statement regarding phone proximity sensors. I have had multiple phones made by different manufactures that experience this to some degree (including the Venue Pro). One thing that I have noticed is that if the phone goes from your face directly into a bright light (outside is most common) it will keep the screen shut off but if the sensor is somewhat shaded it will resume normal function.
I got the same problem too and while it may be a proximity sensor problem, it is not controllable on the user's end. Unless the phone call disconnects magically, a battery pull is necessary.
I'm gonna be on my third one soon and I hope that i won't face the same problem.

Yes i recently got a new refurbed phone and this problem has arised. Complained to Dell and they are going to send me a Brand new DVP. I see a lot of people having this same issue with the refurbs. Currently Dell is out of new DVP due to them upgraing the firmware, so I have to deal with a broke phone till the end of August. Talk about a dissatisfied customer. Im thinking about selling this brand new unit when I get it, hopefully Toshiba has their device out by then
This is a Proximity Sensor issue. You can fix it though in the EM app. You can adjust the sensor readings and the phone will function like normal. Let me know if you need the values or a step by step!

A step by step would be awesome. I like being able to see the screen during a call.
1) Get the EM app, if you dont have it dial ##634# into the dialer
2) Get into the advanced menu by double tapping the black area and typing in "qwertyuiop"
3) Select "RD test", now enter *#6336# in the box that pops up.
4) Select "Sensors", and the "Proximity Sensor Config"
5) Set the following to these:
LED strength - 1
Diode select - 2
Pulse Count - 43
6) Hit set and then you are good to go!
I have noticed that one of my DVP's needs to have this put in again everytime I reboot the phone, the other saves it. Just an FYI for ya!
I get to step 3 and when i clock on RD test, I am prompted with a white box with blue trim and an X at the top right. can you advise on how to proceed?
Oh yeah, Im sorry I forgot that part. Enter *#6336# as the password.
When I dial *#634# it says thic code is not supported.
What does that mean?
I put in a different number combo before and it put me in the EM screen

Knock knock not as responsive waking up...

Sometimes I have to knock knock twice in a row to turn on the device. It works well turning off, but on half of the times it won't turn on. Gotta do it twice. Anyone else encounter this?

I do not have that issue, but I have read in a few posts that it can be dependent on where you are knocking on the screen.

I think the biggest issue is knock speed.... mine works damn near 100% when I slowed down some, and knock slower like it showes at the end of the G2 commercials....
I think it's partially related to the proximity sensor. There are times when I can't get the knock on to work at all and when I hit the power button the screen shuts right back off.
Usually a few swipes over the sensor makes it work again. Sometimes I'll go in and turn the Knock On gesture off and back on and then it seems to work great for a while too.

This is my exact problem. The phone just decides it doesn't want to wake up with knock-on...but after I press the power button, it only turns on for half a second and it's out again. I never tried swiping over the sensor, but hopefully it works because it's mighty annoying when it does it during a call!
I wonder if there's a fix for this?

this, if you are trying to do it like you did on the nokia n9 or nokia 8800 then it won't work
slow deliberate knocks are the only way
waiting on the g2 to arrive, but on my review unit, knock knock wouldn't respond correctly if i left the phone on the table, but if i picked it up, it would work nothing scientific here just an experience of one person and one prototype
I had the same issue... What fixed it is: 1. I found that the screen protector was hindering it somewhat. 2. Go to settings->display->screen-off effect-> and change it to simple. This REALLY seemed to help. Let us know!

I did notice it does seem to behave better when set to simple for the screen off animation.
My screen protector does have a cutout around the sensors. Keeping the sensor area clean enough to qualify as having OCD does seem to make it work properly the first time, every time. Maybe it's overly sensitive?
Edit: Scratch that. 30 seconds later it's behaving erratically again. Maybe it's not the fact that it's clean, but the swiping over the sensor that temporarily resolves it.
it also seems to work much better when knocking at the top of the screen where the statusbar would be.
So I ended up swapping the phone out over the weekend for a new one and now everything seems to work just fine. Seems to indicate that it's not a software problem, but rather a hardware issue with the proximity sensor.
Guys if your covering the sensors when turing the device screen on it will turn right back of on you. It's a feature LG implemented so the device wouldnt wake up in your pockets. Don't cover the sensors.
Need a little example? Grab your phone and cover the sensors and knock knock knock.You can knock till the cows come home but it will not turn on. Same thing goes for the power button but its a little delayed and will turn the screen on for half a sec and turn right back off. Practice not to do this because your phone isn't broken. There is actually a thread on this deep in the forums somewhere but its been forgotten now.

This is true however there are indications of problems with the proximity sensor as well. Some of the devices are behaving as if tree sensor is covered even when it's not.

Thanks for this.. Very insightful.. I tried it immediately LOL
I had the same issue. I have no case or screen protector on, and was not covering the sensor when trying to wake the phone. For some reason though, knocking wouldn't wake the phone, and pressing the power button would only turn the screen on for a few seconds. I want even given enough time to get past the unlock screen. I went into the store and they are sending me a replacement that should come in later this week. It doesn't happen all the time. It is much more noticeable after receiving a call though.

Definitely is dependent on the proximity sensor. If i just have my thumb on the edge of the phone by the sensor it will display this problem. Even with my finger a half to one inch above it will do this. I will be paying close attention to the proximity sensor from now on when it doesn't work. Still have a few days to return and thought i had an issue but maybe not.

sometimes its also greasy fingers, at least in my case, rarely though
As long as you tap twice the same place it's working fine. If distance between first and second tap is greater than 1 - 1.5 cm it won't work.
Got the same problem on my d802...when i left the phone on my table for 2-3min it wont wake up on first knock knock even power key wake it up for 1sec after auto turn off again....even with no screen protector....i noticed that sometimes there is a delay about 5-10sec after knock knock and screen turns on....other thing i noticed when i knock on immediently after turning off it works 100%....BUT i also noticed when i knock on after a while it turns on and i can unlock got vibration and sound of the unlock but i cant see anything. Screen looks like its off but when i look closely i can hardly see widgets and when i set effect to tv out i can see the effect by pressing the power button...when i press the power button again screen turns on like normal...i noticed sometimes on a rerboot the lg bootlogo disapears the led is working an showing all colors but the boot animation is gone like the screen is off at the bootup...dont know why after the bootup the pin lock screen is showing up normal....sorry for my english^^

[Q] G2 "ghost clicks" screen sensitivity

Has anyone noticed that their screen is picking up "clicks" without actually touching the screen?
on occassion my screen will detect a button click even if i haven't actually touched the screen. It's starting to get annoying, but I don't know if that's just the way the phone is, or if i'm too used to a capacitive screen rather than a heat sensitive one.
i had this happen a few times. not enough to bother me that much. it happens sometimes when my finger is hovering really close to the screen, like i'm getting ready to press on it but not yet because i'm still reading whatever it is on the screen, and then it ends up clicking it anyway. i think its happened a total of 3 times for me. 2 other times though, i've had the screen do double taps when i was just swiping around. trying to scroll up and down on a webpage and it registered as zooming in. i did do some zooming in and out a few seconds prior so i think for some reason it was "stuck" on double tap mode or something. had to switch the screen off and on to fix it.

yea it does the same thing for me as well. I sometimes go to press a letter and the letter gets pressed twice. it's really annoying. i'm hoping that if i buy a screen protector it will get better but i'm betting that I'm gonna have to battle with LG's terrible customer service.
Never happened to me. The screen (as with every other smartphone I have had) doesn't react unless I'm actually clicking. Even if I touch the screen with the SLIGHTEST touch I can do, it doesn't react. Which is good, no problem reacting when I actually click.
I guess it might have something to do with my fingers being hard as metal due to guitar playing or something.
On mine it seems to get worse as the screen gets oily. If it starts to wig out, I wipe down the screen and that usually solves the problem for a couple days.
When my screen gets overly sensitive i turn the screen on and off again. Usually fixes it.

Maybe i'm just crazy, but when i spend this much on a phone I shouldn't have to turn the screen on and off constantly to get it to work.
Hopefully LG realizes this is a problem and rushes out an update...

it happened to me... not only that the screen freezzes from the ghost clicks... the clicks are on middle of the screen staying... for example by playing Plants vs Zombies 2... the screen doesn't react at all.
I think that has something to do with the "smart-stay" or with the screen time-limit.
... plus of that... the phone gets really hot at that time.
any solutions?... or back to guarantee?
Greets.
Never happened to me, however I know exactly what you're talking about from using cheap Chinese tablets. Therefore I suggest getting it fixed or exchanged.

Same here, works this way, slightest touch wont react, actual press would.

S6Edge+ cracked screen, wake up problems

i have a S6 Edge+ and its got a cracked screen. it has a big black spot the size of a fingertip on the right middle like something stabbed it maybe.
sometimes when i got to wake it up, phone is on and i press the power button the lights on the bottom come on, the cascade window button and the back button............but the screen does not light up. it kind of flickers and i see the permanent damaged part, a green strip down the right side of screen but does not turn on.
sometimes i have to press the power button to wake up and put to sleep 6 or 10 times for the screen to light up.
my question:
do you think this is simply from the screen being damaged.
have you seen anything like this before on a phone
do you think if i spend the money to fix the screen this issue will be fixed?

Ok, I have booted into safe mode and the problem does not exist. this means its a sofware issue, obviously. Here is the dilemma, I have done factory and hard resets to include the cache partition. How might i go about fixing this issue until they release a new update from android 5.1.1???
Can anybody tell me what core we use to put the touchwiz snappier, I saw one one topic but I can't find it now. We only have to put the code and the phone was so quick like the day we Unbox the phone. Thanks

Just received my Oneplus 5! With issues...

Hey everyone, I just got my oneplus 5 and i seem to be having issues with the screen. First, the capacitive buttons don't seem to be working at times, i'll click on them and it's like nothing is happening while using the phone, the fingerprint sensor does work, while that happens the phone will also have where if i'm dragging an app, it'll just stop moving the app and i'll try and hold the app again and it'll drop it a second later, it's like it's not seeing that i'm still holding on, same thing when using the swipe feature in the keyboard.
