screen wont come back on during call

my wife has the att nitro hd, when the screen goes off during a call sometimes nothing including power button will turn it back on. Anyone know of a fix? did the ATT small update fix this?
Actually it comes back on after a long minute or two. Not very helpful if you need the dialpad or keys, etc.
I have just rooted it for her and installed CWM.
I have added a few proximity tweaks to build.prop
gsm.proximity.enable=false (rebooted twice but screen still goes off)
also used the ro.lg.proximity and the mot.lge.proximity (dont recall exact wording) both were set to a value of 5.
I'll have to take alook into the lg hidden dialer menu to see if I can disable this.
I dont like this sensor on my device either, but I have an option in settings to disable it, which makes it bearable.
thanks for the help guys.
I have noticied LG throws together some junky builds, typos, bad english/grammar. Wonky sensors etc. Incorrect kernel build ReadMe's
I thought I recall someone with another device just placing a peice of tape over the sensor. hmmm..worth a try.
cheers.

Congrats. Today, you learned that most of the "tweaks" found at XDA are utter bull****

What about the tweaks that aren't BS? Are they already included in your CM9 builds?

From what I can tell, pretty much the main thing that build.prop is good for is providing information about the system and software (i.e. info about the build). It's not really used much for useful configurations as far as I know.

networks tweaks actually have doubled me download speed.
I still have faith.
but can anyone answer my questions I posted in ICS SLim thread and PM'ed Andasa , no responses yet.
does ICS slim or CM9 have option to keep lcd no during call? and does it work??
what's working not working? I found changelogs but not a working/not working list for CM9.
and has anyone successfully restored a nandroid from ICS to GB without real issues?
thanks guys.

i doubt the ota fixed your issue as the issue is not one that occurs for every nitro.
I can tell you that when I make a phone call they screen stays no.
what's working not working, well, many of us are running it daily with no probs.
as you prolly know, it is a nightly build so a public list of what's working or not isn't rly part of the deal.
i've succesfully restore a nandroid from both slim and cm9 back to the stock att rom and others many many times. dozens.

thanks good enough.
I will have to give it a go.
would you recommend one or the other?
CM9 or slim?
thank you.

well, I like them both a lot. slim is just a trimmed down version of cm9 and i _think_ it does run just a bit snappier........maybe..but it's not wildly different from cm9. I usually switch back&forth throughout the day.

There's no setting in CM9 to disable the proximity sensor, although there may be a way to do it.

We just got a Nitro HD for my wife and her phone also has this issue. I have not gotten to know the phone well enough to try rooting or anything else of that nature, it's pure stock.
When she makes a call the screen turns off immediately after hitting the call button and will not wake up. When she receives a call we get a glimpse of the in-call screen with the various buttons etc but then the screen turns off. If the other party hangs up her screen turns back on, but if she calls something automated, like voicemail, she can't do anything except pull the battery to disconnect.
I've tried putting my thumb over the proximity sensor, hitting all buttons including power, and nothing makes the screen wake up or turns the phone off other than a battery pull.
The phone was running a build from last November when we first got it (V10i?) and today prompted us to update, so I did that hoping it would solve the problem. The phone is currently on V10j, but the problem persists.
Any help?

If you bought it from a store, get it exchanged for a new one.

actually works much faster on cm9, but therr still should be an optin to keep lcd on during call. i found some free apps that will disable hardware drivers but cant find the name of the proximity sensor driver, only that is named LGE.

Unfortunately it was given to us by a friend after my wife lost her Captivate, so taking it to a store to exchange is probably not going to work too well. As far as I can tell it was never used before we got it--the battery was still in it's own sealed pouch, the texting and driving warning was on the phone, and the phone went through the whole initial setup routine--but they didn't send us the box, I guess to cut down on mailing costs. I was hoping there was a known solution.

Ok, I downloaded two proximity sensor test apps today, but neither showed any activity. On my Captivate I get different readings with Proximity Sensor Finder (market link), but on the Nitro it is stuck at 3cm and it doesn't register anything no matter where I put my hand over the phone.
Can someone whose phone works right try installing this app and make sure that it picks up different readings on this device? OP, if you are still having issues, can you also try this app and see if it is static for you?
Thanks.

Took off the screen protector that they installed at the AT&T store and now the proximity sensor works just fine. OP, do you have a screen protector on your device?

we had an awfully thick one from att. we have since changed it to a super thin one. screen off is not a real problem on cm9, however i feel all devices should have the option to disable proximity sensor/keep lcd on during calls.

It's worth trying to use the warranty on the phone. Even though you dont have the original sales reciept, the phone has been released for less than a year, so no matter when you bought it, it is still within it's year long guaranteed warranty window.
Finished reading the thread, I suppose this post is now irrelevent

[Q] Galaxy Nexus Sleep of Death

Problem: Cannot turn on the screen by pressing the power button sometimes. The screen is black or very dim, I cannot tell. One can see nothing on the screen, and it doesn’t accept any touch input, either. The phone still rings if there’s an incoming call. If this happens, the following several presses (about 10 - 20) on the power button will probably lead to a reboot. The “screen auto-rotate” and the proximity sensor may fail after the reboot, but will recover after a manual reboot.
Frequency: Fewer with higher Rom version. About once per day for 4.3.
Other description:
 The problem frequently happens when I just take the phone outside my house/office, and seldom happens when the phone just stays somewhere.
 The problem seems to be irrelevant to the remaining battery capacity or the uptime, but it never happens when charging.
 The problem seems to be irrelevant to the Apps installed.
 The problem seldom happens in the first 3-4 days after flashing a Rom, but happens more and more frequently as time goes by. My guess is some cache is stuffed by some trash, which causes the problem. The phone may be fine as long as the trash can be cleaned up on a regular basis.
 I manually reboot my phone at most every two days.
Solutions tried, but don’t work
 Flashing official ROMs 4.0.4, 4.1.1, 4.1.2, 4.2.2 and 4.3 following the procedure “adb reboot bootloader; fastboot oem unlock; flash-all; fastboot oem lock”, without google wallet, not rooted.
 Turning off the auto-brightness control, as suggested by some post on the Internet.

Does it look like it goes to standby normally or does the screen show gibberish and then turns off?

Thank you very much.
I think it's standing-by normally even through the screen is black (or very dim, I cannot tell), since it rings if there's an incoming call. I can see nothing from the screen, and I don't think the screen accepts any touch input, either.
Does this answer your question? Thank you.

Was just asking if you had gibberish yes or no. In that case i've got a different issue than you (Suspecting f*cked GPU).
Have you tried a different ROM/Kernel combination maybe it's related to that.

No.
No, I just tried the official ROMs. Any suggestion?

Perhaps it's just busy in the background and running low on RAM. Give LagFix a try. Sorry can't link atm as I am on mobile...

LagFix does NOT help in my case. Any other suggestions? Thanks.

I've also had this blank screen with calls still ring issue for as long as I can remember, nearly 2.5 yrs.
I've always suspected it's my ROM and so I'd try out another ROM'S, BUT no other ROM works like how I'd like, so I always come back to my ROM.
It doesn't happen every single day, but it does happen very often.
I've tried using apps that auto reboot daily, but eventually this blank screen issue will return.
Unfortunately I can't seem to find any solution, so I just put up with it, it's like the 1 only flaw with my ROM.
&
Not to be at all rude, but I'm really glad op has had this issue from testing other versions of Android, cause then at least I know I don't need to give up my great tablet mode ROM.
LOL

I think I've finally found a work around for this screen of death.
Using Exposed, download/install this module/extension:
Disable Proximity
http://repo.xposed.info/module/com.mrchandler.disableprox
It does exactly what it's name is and ever since then I've not once had to remove my GN battery to work again because the screen went completely dead.

NVM
Screen still goes dead.
Anyone find an actual fix to this?

isajoo,
I had pretty much the same problems with my Galaxy Nexus running CyanogenMod 11 M12.
It got better by doing the following :
Blowing dry air in the earpiece… though the proximity sensor is clearly beside it. Can't do any harm though, I guess.
Settings/Applications/All/menu/Reset applications preferences (or whatever that's called in english) : that seemed to do a lot of good to my phone ! However, it's a very unsatisfactory answer on a technical point of view, as I still don't know WHAT was precisely needed. It's a "magic wand" solution for which I can't give an explanation.
Not specifically related, but greatly helped my phone in the responsiveness area : Trimmer (fstrim) (https://play.google.com/store/apps/details?id=com.fifthelement.trimmer), an updated version of LagFix that you may already know
Hope that helped !
(I wanted to try http://www.androidlegend.com/how-to-perform-proximity-sensor-calibration-on-any-samsung-phone/ as well, but apparently, /sys/class/sensors/proximity_sensor/prox_cal does not exist on my phone…)

[Q] touch key lights bug

hello everyone , so i use to have this bug back to kitkat also but it wasn't happening as often as it doesnt now that i have lollipop rom installed on my galaxy tab s T705 , the issue is with touch key lights which stays on even when i have them always off from settings , they act super weird when they are in that mode , they go off few sec after screen is off and if i shake the device they go on again as it looks like they are connected to accelerator sensor or something lolz ,the solution is super easy tho just hit the power saving on and then off again and they work normally again i heard some other ppl dealing with same issue but i wanted to know if there is a perma solution for it or not , im sure its a software issue but is there a way to fix it ?

Install a custom rom like cyanogen or something stock based.

I have the same problem. I usually have it set to turn the lights off after 6 seconds, but after a couple of days they don't work anymore. I would change the setting to off, then on, then back to 6 seconds, and it'll work again. After a few more days, they stop. I haven't seen a permanent fix for this.

Same for me. Would usually opt to have the buttons backlight always off, but randomly it starts actin like always on, although the settings remains 'always off'. Toggling the setting to anything else and back to always off fixes the problem temporeraly.
Im running stock swiss lollipop on my t700.

Yes, this is driving me nuts too! I hope they resolve this in the next update and soon!

Same problem with the lights on after a while even though set to always off. Seems to work properly under 1.5 sec setting option. I would love for the lights to be always off though.

Me too have the touch key settings to always off and found the same problem.
In my case I think it only happens when I plug the Tablet to AC.
Did this happen to anyone under another circumstances?
Thanks in adavance!

I have the same problem as everyone else, which I am very "happy" to hear because I am not the only one apparently dealing with it. I purchased the tablet a couple weeks ago and noticed that even though the setting for the touch key backlight is "always off", it goes on when I open the case, and sometimes goes on and off and goes weird. I contacted Samsung and they requested that I send in the tablet for repairs, so I did. At the same time, I contacted Amazon and they sent me another Tab S tablet. I have a month to return the other one so I figured I'll try this second one and see if I continue to have the same issues like the first one. Sure enough, I had the second tablet for less than a day and it's doing the exact same thing! So far the 1.5 second setting seems to keep the darn lights off. Sometimes doing a soft reset will fix the issue temporarily, but not permanently. If anyone figures out how to fix this, let us know! I'll be following this thread. I hope there's a software update to fix this.

I believe this is a software bug so all tab s running the 5.0.2 lollipop will have this issue.
And to reply to the other poster: The problem will occur after a while, the lights will just turn on and stay on when you wake the tablet. Changing the setting and choose Always Off will fix it but it will come back after a while.

Is there a way to get it back to the stock ROM? I'd rather avoid this light issue until an update to correct this comes out. Thoughts?

I heard that there's a new update available for the Tab S. (I already returned my tablet before my 30 days to get a full refund.) Did any one get the new update, and if so, did it fix the issues like this touch key light?

Hey,
I had this problem on the original KK software - upgraded to Lollipop a few days back and I still have the bug... in fact, it is even worse! Occurs more frequently than on LP.
I wouldn't mind leaving the lights on all the time, but they're so damn BRIGHT, and there's no way to adjust the backlight intensity!
Cheers,
Su

I found this solution on another forum...
If you enable smart stay, the touch key light duration will work properly.

Any further movement on this?. I've found that if I take my tab out of the book case the problem goes away. Seems like it's a bug with the case sensor.

No movement that I'm aware of. I'm really frustrated that there hasn't been a fix after all this time. I'm holding out hope that if there is ever an update to Marshmallow, that the issue will go away. Interesting observation about the case -I have a book case on mine. I'll remove it and see what happens...

screen far too sensitive?

New member here, first post.
I had my g4 several weeks ago (uk version). Great phone, however recently the screen seems far too sensitive. Sometimes apps or other features are activating on their own without me pressing on them.
I looked in the settings but havent found a way to resolve this. Can anyone offer any suggestions?

Just to clarify a bit more about my issue.
Its like the "floating touch" some phones have, where i can be an inch or two away from the screen but it still activates. More rarely, it seems as if it was activating by sensing light or movement. Strange. Is the g4 supposed to have this type of function?

That sounds like a problem. The G4 is actually known for lacking sensitivity and yours is doing the opposite. enable this settings to see if it is actually detecting ghost touches.
Settings, About Phone, Software Info and tap on 'Buidld number' 7 times. Then go back to settings and tap Developer options, enable 'Show Touches'
if the dots show without your intervention, then it's likely due to faulty touchscreen.
Anyways, do a factory reset and see if it helped.

Does reset solve the issue? , happening on mine right now. Appreciate your feedback. Thanks

Same here, on Imperium and Stock rom, I have the phone since 6 months and it is a really random issue... my bootloader is unlock so I don't know if I can send it to warranty.
For information I have enable the touch "tracing" in developper menu, and when the issue occurred it's getting me perfect vertical line from bottom to top screen, and open a lot of apps..

And from the sound of it... Yours pretty much ****ed, at least to my knowledge. Hardware screwed and no warranty. Just bought mine like 3 weeks ago, and hated it so much. So much hyped, but the experienced is so far ****ty at best.
I suspect mine hardware issue. This seems like it's gonna be the first, and the last LG for me. Even mine with warranty still intact. Blackberry used to give this feeling long ago with their ****ty storm. Now, LG and blackberry can share that same ****ed up grave.

As madgibbon indicates, I was on Accessibility / Motricity / Response time (my phone is in french so i'm not sure if it will be exactly like that on yours) and I have set to "Long".
Since that, the issue is no longer appear, I have also switch to rom V20F (Turkey) with still the same setting for accessibility, and I don't have the issue anymore.
I don't know if it is a hardware issue, my phone falls maybe 4 times but with a case and from a little height, no broken glass or something else.
This is all the things I tried before that ;
Using flipcover (QI charge and quick circle), I have tested the "normal" case but same issue
I had a glass protection, I have removed it and cleaned my screen, same issue
I have done lot of hard reset (i'm kind of full wipe addict), same issue
Only the solution of madgibbon works fortunately, thanks mate
I'm also a bit disappointed by this phone, it is great sure I mean fluid, great camera etc... but I have some little issue that ruin the experience unfortunately (this issue with touchscreen, i'm experiencing issue with my Chromecast too that i don't have with other phones, some heating, I don't find the battery usage so good since MM, can't relock bootloader since now). I don't blame LG because i'm using some of their products and I'm / was really satisfied with : Optimus 2x, Nexus 5, TV, Monitor, Sound Bar. Anyway, waiting for 2016's Nexus and I will see if I switch or not.

Screen problem after all, just picked my phone up from the place that I bought for under warranty fix, and they told me they did replace for a new screen, and all is looking fine and dandy for now. Hope it stay this way, finger crossed. 3 weeks purchased and already this problem. I doubt this thing will last.

Display wakeup issues after screen replacement

Hey guys,
About 1 month ago the screen of my OP3 broke and I bought a replacement on eBay.
After the replacement I encountered problems, which only occured from time to time. Sometimes when waking up my device the screen stayed black.(Like on every 20th attempt it happened once). After pressing the power button some more times, the device finally unlocked. I am 100% sure that the device always unlocked on uneven attempts which means that the device at least woke up software-side.
I was totally sure that my replacement screen was kinda flawed and it is a not fixable hardware problem.
Then one week ago I switched from official LOS15.1 to the unofficial LOS16 rom and encountered big differences. The problem got noticebly worse. Waking up the device was a pain in the a**, it never worked on the first attempt on this rom. It's not unusual that it takes between 11 and up to 60 tries to wake up the device which makes it nearly impossible to use the phone. As before, the screen at least turns on software-side after every attempt. I can see this because the hardware buttons always light up.
Now after one week I switched back to official LOS15.1 and voilà, out of 20 attempts, the device instantly unlocked 19 times.
I know it is hard to understand and even to analyze such kind of problems, but there must be some solid solution for my problem.
Atm my clue is that original screens always offer more functions (e.g. gestures) than replacement lcd screens. Those functions are always connected to the software(rom). Is it possible that there is any other function (e.g. anything related to tap2wake or deepsleep) which is able to prevent my screen from turning on?
To deliver some more infos:
- I used standard system settings on both roms to test this out.
- "prevent" accitential wake up is turned off
- tried to disable gestures
- I tested my proximity sensor via an app, it seems to work flawless
- waking up screen in twrp is also very difficult and needs around 15-20 tries. Does anyone see any pattern?

You most likely got a bad part. OEM like One plus and xioami are known for using something called product binning. Which means their parts have a higher failure rate then other oems. They also dont make extra parts really so what you got was most likely just a generic screen like you can buy at any shop in China.
Nothing you can really do about it except try a different screen but to be honest I would get a different device and this time dont skip on the price. You get what you pay for and when a good device is cheap there is always a reason. (why do you think most of the owners and mods of XDA run Iphones as their daily drivers and leave android for a hobby)

Hey guys,
About 1 month ago the screen of my OP3 broke and I bought a replacement on eBay.
After the replacement I encountered problems, which only occured from time to time. Sometimes when waking up my device the screen stayed black.(Like on every 20th attempt it happened once). After pressing the power button some more times, the device finally unlocked. I am 100% sure that the device always unlocked on uneven attempts which means that the device at least woke up software-side.
I was totally sure that my replacement screen was kinda flawed and it is a not fixable hardware problem.
Then one week ago I switched from official LOS15.1 to the unofficial LOS16 rom and encountered big differences. The problem got noticebly worse. Waking up the device was a pain in the a**, it never worked on the first attempt on this rom. It's not unusual that it takes between 11 and up to 60 tries to wake up the device which makes it nearly impossible to use the phone. As before, the screen at least turns on software-side after every attempt. I can see this because the hardware buttons always light up.
Now after one week I switched back to official LOS15.1 and voilà, out of 20 attempts, the device instantly unlocked 19 times.
I know it is hard to understand and even to analyze such kind of problems, but there must be some solid solution for my problem.
Atm my clue is that original screens always offer more functions (e.g. gestures) than replacement lcd screens. Those functions are always connected to the software(rom). Is it possible that there is any other function (e.g. anything related to tap2wake or deepsleep) which is able to prevent my screen from turning on?
To deliver some more infos:
- I used standard system settings on both roms to test this out.
- "prevent" accitential wake up is turned off
- tried to disable gestures
- I tested my proximity sensor via an app, it seems to work flawless
- waking up screen in twrp is also very difficult and needs around 15-20 tries. Does anyone see any pattern?

As an experiment, try stock OOS and see whether the issue goes away.

Hey there again. I know my answer is kinda late but I wanted to share my experience. So I tried like 10 different custom ROMs with different Android version. The problem got even worse sometimes.
Anyway a few days ago I installed stock OOS and the problem is fixed now. I could not believe at first, but after excessive testing I am 100% sure now.
Anyone can tell why? Is the stock display driver proprietary?
TBH I always used to use custom ROMs (mostly CyanogenMod and now Lineage. Now on stock rom O feel like everything is better than ever before. Battery life, performance. Some features even offer more customization than custom ROMs.
I always thought the opposite is the case since custom roms advertise things like this. I will definitely stick with stock rom for now!

Thanks for the confirmation. The cheaper screens seem to have an issue which is not faced by the costlier ones. I have found while roaming the threads that sometimes flashing OOS helps. May be a driver issue.

My understanding from what I've read, third party displays needed kernel support.
I paid OP to replace mine - no problems.

Hi!
I'm having a similar issue with my Oneplus 5. Had my screen replaced (new one: OEM) and now it doesn't wake up most of the time either using power button or double tap or fingerprint scanner. I tried everything that I read on forums but nothing worked. Now I seem to have found a solution that I haven't read anywhere yet: I turned off night mode and now it's working as it should. Actually, whenever I want to use any screen adjustment feature like night mode, reading mode etc the screen doesn't wake up. But if I keep the default settings, there is no problem. The issue is definitely the new screen because before that I used night mode all the time (I mean after dark). Now I'm still thinking if I should return the phone to the repair shop and ask for another screen (they offer one year warranty after the repair) or just deal with it... I mean these OEM screen are cheap for a reason (as someone had written here before) and there is no guarantee that the next one will be good, and I don't feel like waiting weeks again for an uncertain outcome, also I can live without said features (gonna miss night mode tho'). Any suggestion? Should I give it a try? Maybe the repair shop made a mistake during assembly? Anyway, I hope this comment will be helpful for those lurking for a solution for a similar problem.

Did you try OOS?
OEM screen is not cheap (atleast compared to what is offerred online).
May be you are better off with what you have since you have found a work around. Who knows what you will get next time?

Yea I have same problem it works totally fine on oos but on custom roms it is ****ed up

Thank you also for confirming that on OOS there is no issue. Looks like the cheaper of the online replacements have this issue while the costlier ones don't.

Funniest thing is I have a slim ROM backup on 7.1. and that works fine so like what the f--- any ideas people?

Yes, I have the same issue and I wanted to revert back to Stock OOS, but I just tried Caesium latest kernel, and the display wakeup issue seems to have gone. I'm using Havoc OS 2.3 based on Android Pie.

Guys the latest mad kernal reborn it wakes up all the time
At least for my screen
It used to be worse on all the other kernals

Finally found a solution
I had same problem on custom roms after replacement of display of my oneplus3...i was on oos 5.0.8 i had no issues in that but am a custom rom user and now the solution is flash any rom clean flash not dirty flash and flash gapps then flash any module if you want like magisk and then reboot setup the device and after first boot flash mcd custom kernel and yippeee enjoy... Present am on havoc os with no issues... Try and let me know...
