2nd screen issues - LG V10 Q&A, Help & Troubleshooting

Has anyone had this occur?
It's happened twice now and a factory reset fixes it but only temporarily. If the phone is left alone, the second screen will normally dim to roughly half it's brightness on its own. This is normal, however mine stays continually at full brightness and has stopped dimming, again. Also if the proximity sensor is covered by either placing the phone in your pocket or turning it screen down in the table. The screen will completely turn off. Once removed from the pocket or turning it face up, it will normally turn back on. Easily seen by testing this. However, mine has stopped turning off on either example. It stays on constantly no matter what. I have done a factory reset twice before and it fixes the issue but that is getting old. Does anyone have this issue or advice on how to fix this? I would be very grateful. I'm tired of resetting my phone.
Thank you

No one knows eh? It's a mystery to me as well. Wondering if it's a proximity sensor problem. ?

Hmm.. I installed a few applications to test the proximity sensor. Turns out it's not working. This in turn prompted me to search of the issue with regards to the proximity sensor malfunctioning. I discovered a couple threads declaring similar problems with the second screen after folks disabled system applications.
My phone is not rooted but I've disabled Instagram and Facebook through the applications settings on the phone. This was dinner sometime shortly before the recent malfunction. These of course on the v10 are system applicants, at least on T-Mobile.
Long story short, the only way to fix it sounds like what I've been doing, factory reset.

The proximity sensor is definitely not working. It's pretty obvious during a phone call as well. I'm going to utilize LG bridge to back up tomorrow. Then I'll do a factory reset.
There's definitely a connection when disabling system apps through the normal application settings route. Not sure how many are affected by this. But if it ever effects someone else, remember this thread.
I'll post results tomorrow. At this point I'm convinced it's not hardware related and if things return to normal afterwards. That'll confirm my suspicions that there's a bad bug floating around to what degree I'm not sure.

[Q] Spastic touch screen

My touchscreen has been doing some weird things for a while now. First of all it just stops responding altogether and a temporary fix is locking and unlocking the phone. The second issue is the screen taking a mind of its own and pressing itself to which I can only watch and hope that it stops. I thought these two problems were software related but I've flashed a few roms and kernels and have factory reset the phone too, yet they still exist. So does anyone have any solutions or has had similar problems? The annoying thing is that the issues happen on and off so there's no solid way of showing it to my carrier so they can give me a replacement phone.
I had the same issue, only while charging my phone. Seems like another bug or something

try wiping the phone's surface with very slightly damp cloth, it could be the dust & water causing all sorts of problems. make sure its clean. If it continues, contact the LG service. they MUST fix that kind of error. but get rid of your root
It's a hardware problem (touch screen)
I had exactly the same problem. I've sent the phone in for repair and had the touch screen replaced. Now everything is working fine.

You don't have an app installed called more bars do you? That app automatically enters airplane mode during low signal to conserve battery.

HTC One
So I'm having this problem as well, on my new HTC One... it goes into airplane mode nearly every call I have... I'll probably have to go back to my iPhone if I can't resolve the issue. As stupid as it sounds, I'm fairly confident it's my ear touching the screen that's "navigating" into settings and turning airplane mode on... if I'm 100% concentrating on not touching the phone's screen at all, I don't have the problem. But if I'm talking normally, it never fails, the call drops, I look at the phone, and I'm sitting on the settings page with airplane mode on. I honestly don't know how this doesn't happen to everyone... I *THINK* my ears are normal!? Anyone come up with a solution??

Is your proximity sensor working fine? Is it covered with a screen protector?

Thanks... I installed the sensor app... seems to be working ok... it's showing "all or nothing" (9cm or 0cm) and seems to indicate the duration I hold the phone to my head. If I move my head around (not necessarily away from the phone) it indicates that the sensor thought I wasn't in proximity the full time... so perhaps there are brief moments the OS thinks I've pulled the phone away from my head. Maybe that algorithm needs tweaking (e.g. maybe wait 1-2 seconds of nothing in proximity before turning on screen?).
I don't have a screen protector.

found this on the htc one forum: http://forum.xda-developers.com/showthread.php?t=2259526
I didn't read it, but it looks like you are not the only one having issues with the proximity sensor...
So I know this doesn't help much but wanted to add I'm having this issue as well. Not every call but maybe every couple of days or so. Does seem to happen when I'm using the phone, not an ear piece, and I'm moving around a lot. So might be something with the proximity sensor, though there is not quick button I could be hitting with my face to turn airplane mode on even if the screen was on. I have also noticed a lot of strange network issues where my single bounces between 4g, 3g and hsdpa often, which I've never had a phone do this much before. I can actually sit there and watch flip back and forth. So I'm really thinking the HCT One has some manufacture issues that are not being addressed. I'm about ready to send this thing in.

SOLVED - Xperia Z Ultra - LCD Screen Issue while TURN ON - New Problem - UPDATE 8/15

I've had my XZU for a week now, everything has been working fine so far. Nonetheless I've noticed lately that when I turn it on I will see like a curtain or shade of colors from the top down up to half of the screen (it's like a flash, quickly disappearing), apart from that it will resume from sleep fine and no other issues, nonetheless is weird that this is happening now after a week of usage, I hope is not a symptom that something worse is about to happen. I have attached a Youtube link to a short video I just recorded.
NOTE: I do not think is a software problem because I booted the phone is "safe mode" and the exact same thing happened. It seems like a hardware issue that gets worse over time, because at the beginning happened once out of 4 times I turned it on, now is once every two times. I do not see a very good future with this phone
http://youtu.be/1ZucFrMvg_w
UPDATE 8/15: All my screen issues have been fully resolved with FW .475
So we have our own thread for the curtain now.
Sent from my C6802 using XDA Premium HD app
I think the issue is Power Management related, let me explain. If I turn on the device after being idle for a while (device is COLD) there will be no curtain issue, but if I turn it OFF and then ON right away (device is WARM) it seems the phone is entering a power save state and is not ready to be powered on again and that's when you get the curtain issue. The result seems to be very consistent with my explanation.
What I do not understand is that why this problem started happening after one week of usage, I thought it was application related but after my "safe boot" mode where no new applications are running only stock apps and I got the same result it can be application related. Also I thought that maybe the Stamina Mode had something to do with it, but it does not.
My last theory is that there is a piece of hardware that is getting degraded over time and when the phone is warm it will produce the curtain effect, if that's the case this is really bad, because the whole phone could stop working down the road. but it's just a theory.
Oh man
My experience with similar LCD issues has been around poor connection between the LCD screen and the motherboard. However, I'm by no means an expert on this.
I would definitely be claiming under the warranty for this.
I spoke with the vendor in Singapore and told me this is a known problem by Sony and they are working on a Firmware update. They suggested to keep the phone until the FW will be released in September and then decide if I will exchange it or keep it. The vendor also extended the Return/Exchange window until October so I will have enough time to test the phone after the FW update.
It's good to know that Sony has acknowledge the problem and is working on a solution.
Any chance Sony will do a firmware update to resolve this?
So it might be a firmware issue? I sure hope so

UPDATE 2
I think the problem is Power Management related, because if I leave the phone idle for 5min and then I turn it ON it will happen the issue you are seeing on the attached video. But if you turn it OFF and immediately turn it back ON again it will be fine. I think what is happening is that after 5min the phone will enter into DEEP POWER SAVE. The threshold to enter power save mode is around 15 seconds. I would say is something that should be able to be fixed with a Firmware update, but my only concern is why this problem did not happen during the first week, that behavior makes me think it's a Hardware problem that developed over the first week of usage, meaning a defective device.
NOTE: As you can see at the beginning of the video the phone has been Factory Reset, so there are no third party apps and anything wrong on the configuration.
http://youtu.be/vgnILc3ib8M
Mine did it the first day. I noticed it did it about 3 times that day. And I agree with you it might be the power save mode. Hopefully it gets resolved.

My Z Ultra does exactly the same thing but it does not worry me. Seems to be a software glitch that should be easily fixed.
Mine happens when i am taking calls and i turn the screen on or off. Other times it is random but normally when i have been using the device for a period and then turn the screen on and off quickly after using it.
But yeah, i do not think it is an issue to worry about. If it was serious, surely the screen would be having issues a lot more when it is on and not under these specific situations?

If it's a software problem how is it possible that during the first week the phone worked fine?, even after a factory reset the problem will still be there, that means (to me at least) that a hardware issue develop during use for the first week and now it cannot be recovered

Phone display turns black with phone call ??

I noted each time I make a call, the display immediately turned black. It auto turn black without me even taking up the hone up to my ears. I needed to press the power switch to have the display lit up again. Is this a proximity sensor defect ??

Yea I'm dealing with the same issue on my at&t model, it's definitely a proximity sensor issue. Also, I find that the proximity sensor functions relatively OK outside of the phone app when I'm on a call in terms of lighting of fading to black...I haven't found a fix yet, hopefully it's a software issue though somethings telling my it's not... Just another defect in a long line of LG phones as of late

I have a same issue but clean the proximity sensor and it will work. The proximity sensor is next to the speaker. Clean with your t-shirt or jeans.

I've cleaned it several times to no avail
I have noticed occasional "quirkiness" while in the phone app, but not to the point of requiring a battery pull. Example, connected via Bluetooth, while plugged to a charger in a call, no way to wake the phone without pulling the charger.

Thank you. Thank you. Your proposed solution works very well. Now no more this problem. Had never thought the sensor could be dirty or blocked over time. I had the phone only about 2 months
Problem update
Okay, I've found new info on the proximity sensor problem. Firstly, I noticed that my proximity sensor still works with the second screen, if I cover it up when my screen is off it goes black and comes back on when I remove my finger. Secondly, if I was on the phone but not actually in the phone app it would behave normally sometimes. Now today I found out that when I'm in the phone app, if I'm talking on the phone through the speaker the screen does not go black, as soon as I take it off speaker, the screen goes immediately blank. Still have not found a fix, but just more info that may help define what the actual problem is.
anyone have any update on this? this issue seems to be getting worse for me
Same issue, drives me nuts. This phone is a disappointment to me overall. Have an S7 on pre-order with Verizon. Can't wait to get my hands on it!
Had same issue just happen on the AT&T LG Escape 2. (Yes I know its a year since this thread was started)
It was the proximity sensor but the "T-shirt wipe" method didn't work for me.
What I did realize there was some gunk on the sensor, and I used a cotton swab (Q-tip) with alcohol and rubbed it till it was visibly clear of gunk. Now it works fine again..

Super Deep Sleep?

My phone's always-on display will turn off. I can't bring it out of it's 'slumber' anyway other than plugging it in. It instantly pops out of sleep and works fine. I'll lock it and while I can see the always-on display the fingerprint reader will unlock it with no problems. This just started in the past hour for me. I've tried resetting the phone and the issue still pops up, and quickly at that.
Are you using a case or screen protector? Could be something interfering with the ambient light or proximity sensor causing the phone to think it's in your pocket at all times?
Edit:
Actually just tested this. Covered the top sensors and the always on display turned off and fingerprint sensor no longer worked just like you described

You may be right about that. I'm using a lifeproof case and I had just opened it up to clean off the inside (I had shown someone the phone earlier and dog hair found its way to the inside of the case). Funny thing is I turned it completely off and let it sit for a time, as opposed to the restart I did earlier, and it's working alright now. Maybe I just needed to reset it's calibration by resetting it?
Anyone know how to disable this weird dependence on the light sensor? I just don't understand why it would ever disable itself because it's dark.

I read this is a feature of the phone. The always on will turn off in your pocket or in a darkened room. Nice idea since you do not need to be using the juice then. You can test this in a dimmly lit room by cupping your hands over the display to block the light.

Sure, but it won't turn on even when I press the back button. Pretty obnoxious when I'm sitting in a blacked out room and I have to hold it up to the computer screen to activate it.
Yeah, I'm sorry I didn't read the thread carefully. That sucks. I'm in a dark room now watching video. The display turned off, I heard a notification, when I picked up the phone it came on. I do not like that that the led notifications stop. I'm not sure what happens to sound notifications when the always on goes off. I prefer to set the phone silent until a certain time in the AM and then use a sound profile to get notifications and a low volume.

I'm thinking it was the Lifeproof case I have on it. It all worked fine for a week then when I tested the case for waterproof it failed (the phone wasn't in it). I sent for another one and it seems to be working alright now. Maybe it had something to do with the inside of my case getting wet? I don't know.
Great! Enjoy your phone g why are we still calling these things phone?). I like the G5. Now that we have torur I am hoping their for some nice tweaks.
I've had this happen too and it made my life proof case useless because I couldn't use my phone with it on it I still have the issue once in a while but not nearly as often anymore
