It heats in the pocket - G3 Q&A, Help & Troubleshooting

I recently purchased the G3 in the uk so its the D855 version and i updated the software to 10g and today i noticed something weird after i put it in my pocket and i was driving , it heats up. First i thought its because of the knock code but after i switch it to swipe it still heats up. I keep it in my pocket with the screen closest to my skin. I will try to keep it with the screen up and see what happens...probably its because of the sensors if u apply slight presure to the screen while in pocket somethings happens...im waiting for your replies....tnx

It heats up especially on the higher part more than the bottom

try disabling knock on/off in hidden menu
3845#*855#

Ok tnx ill try
LG G3 D855 stock ,no root

Anyone?

uhm one thing i can think of is what usually happens with me.
i'm using quickcircle case.
screen accidentally turns on, then again accidentally opens camera.
and that stays on.
i noticed that because i had many blank camera shots on my gallery. hehe
the worst was when i installed the torch app that can be included in quickcircle apps, it accidentally opened and the LED flash was on all the time in my pocket.
maybe LG should find a way to improve on how to prevent accidentally opening apps when in pocket with or without quickcircle case.
and maybe program the camera app to put itself in standby when it's not in use for certain seconds or minute.

Disable the knock on/off like what suljo said. The phone does sometimes turn on when in your pocket, especially when it could sense your touch due to moisture built up on the lining of your pockets.

I understand but this is not cool at all cause i really like this feature. I paid 450 british pounds on it and it shouldnt do that

It may be the Knock Code but I wouldn't think that alone would have your phone heating up so much in your pocket.. Maybe but idk
What else do you have running on your phone? For example like do you have things like OK Google running and Google Search, Location, Sync, WiFi Always Scanning turned On?? Could also be a WakeLock.. Maybe use a WakeLock Detector just to make sure.
I'm not discounting the Knock Code idea, although my phone doesn't heat up like this. There may be more going on that's all

the knock on/off feature gets activated in your pocket there are 2 ways to solve this
1)kernel wise (proximity sensor preventing knock on in your pocket)
2) covering your screen before putting it in your pocket (turning it away from your leg might help also)

You could also use the app AnyCut and create a Shortcut on your home screen that you'd just Toggle the Knock On Feature on and off. It's very easy to do and one way to quickly disable the feature for those times when that may happen but still having a very easy way to turn it back on too.

I think its the knock on ...i turned it off and it doesnt heat anymore...weird thing though...i bought a cheap silicone case i turned the knock on on and it doesnt heat anymore...and i also turned off wifi search when its off....tnx guys for the help

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.

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

[App] Flip Case Control - Auto Screen On/Off

I need help with testing for this device and flip style cases.
I had a bunch of requests for Wave Control to have this functionality. Flip Case Control simply turns off the screen with the case is closed and turns it on when it is opened and it is designed to work using as little battery as possible. (I left it running all night ~8.5 hours and the battery dipped 1% more than usual)
IMPORTANT: If your case is black or dark on the inside, the sensor doesn't read correctly when the case is closed. To fix this, put a piece of light colored tape on the inside of the case where it lines up with the sensor (located next to the front camera)
Note: A Samsung based ROM is required. CM doesn't seem to work well.
Demo video:
Thanks! (crossing fingers it works without needing modification)
Edit (10/20/2012)
Taken out of beta with V1.05
Play Store Links:

I haven't tried the app yet but I would recommend a setting where the service can be disabled/suspended while charging for people who leave the case open or take it off while charging.

Hmm, yeah I could put that option in. Also probably need to have an option to disable if in landscape mode so fingers don't set it off.

This should use quite a bit less battery than that app. The method employed on it prevents your phone from reaching deep sleep when idle. But, because of that will react quicker. So, it's a tradeoff. I chose battery life over response.
Also Flip Case Control is compatible with lock screens if you need the security.

You can just hit back or home and it will stay running in the background. I think I'll add in a close button to make it more intuitive.
Neat Idea
Great Idea .. And Seems to work really well
However I have a Black Flip Case ..
So Doesn't Work for me .. but adding white area to case idea did
You Def need a button for main screen thats says: OK
Or better yet .. ON - Off Buttons lol
Will See how it does on battery life.
Great idea, looking forward to getting my new case and trying this. Thank you

Really - Really Liking the new program ..
Its Soooo nice to have the phone turn on automatically!
Not sure whats up .. But I rebooted and the program didn't restart
with the phone .. had to restart the program and it started working.
Also .. Over night I checked battery level it was at 81% when I went to bed.
In the morning I had 78% - 3% over night!
Just a thought to save battery ..
how about from 12am - 6am have the program unload / turn off ?
That way should be 0 loss over night
BTW .. I removed the white tape ..
And it is working fine now with my leather gray case! LOL
No Idea why it started working.

That's a good idea. I can set it up like in my other app Data Sleep.
I just put out a new version to the play store. But, now I'm thinking it may behave differently on the T-Mobile version due to the different sensor..
Could you try out this version here and see how it works?
This one is the full so the on boot option is enabled.

How about with the tape again? The changes shouldn't affect that though... I think.. unless the case isn't flush. I'm using the light sensor to confirm the case is closed.

Well .. Something changed .. because it was working fine before update. lol
And the case does fit snug / flush against the sensors.
The inside of my case is a gray .. out side is black.
Yes it works with white tape .. kinda ugly fix though. lol
However .. like i said the screen time out works. ( set to 30secs )
and when i open the case it turns the screen on.
So happy with how it works without tape for now

Version 1.10
Just put out to the Play Store V1.10:
-Reworked detection method much more robust now
-Option to disable the sensitivity changes from V1.05
-Option for longer timeout for Screen Off
Let me know if I broke anything!
Works great on Tmobile.
Does the newer version offer better battery savings ?
Im more worried about Bat life than anything else what would be optimal settings for that.

New version should be about the same but handle different open and close speeds better. For the best battery life, don't enable the longer screen off timeout... since this leaves the screen on longer and so that uses more battery.
Next version will have a night time disable option so you can set times to turn off the sensor since you won't be using the phone while you sleep. It won't have that much affect on battery life (only really drains at most 1% overnight as it is) but will keep you from running the sensor 24/7.
Version 1.20:
1. New Swipeable UI - Swipe left for settings, Swipe right for Night Disable
2. New Night Disable Mode - Shut off the sensor at night while you sleep. Saves a tiny bit of battery and keeps you from keeping the sensor on 24/7.
3. Auto Start on Boot works on the Trial Version now.
4. Bug fixes
I'm still not happy with the UI. It's functional for presenting the new functionality but I need to polish it up a bit.
What do you all think?
Any other features/options you would like to see?

Crazy Touch Screen Not Responding Bugs with my G3

So most of us know about the System UI crash when using Chromecast, but this is even stranger. [Edit: an OTA update fixed this.] Some times, when I wake my phone up at the lockscreen or at times in the middle of a call - the touch screen stops responding. I can press and/or hold the volume buttons and there is a response on screen but I can not interact with the phone at that point. I can't continue to do battery pulls everytime. This is crazy. I'm on stock software. No crazy mods or anything. I've done a reset in the past and flashed the stock package again but this still happens every few hours. Only happens when the screen just wakes up...
Edit: This is a confirmed fix for me.
If you face the same issue, try:
open dialer
press 3845#* INSERT THREE DIGETS OF YOUR MODEL NUMBER THE PRESS #, for example, I am the F400K, so 3845#*400#
Hardware Device Test > Touch
update touch firmware
touch firmware version
wait 10 sec
reboot
I would say there is a misbehaving app causing the phone to lag in wake (that is all the unresponsiveness will be, extreme lag).

@Lennyuk - tried for over 30minutes after leaving it alone, I doubt it's a delay... Battery pulls work, but that's not the point.

Totally agree with @Epix4G on this one. I am assuming you had a korean variant? The SK Telecom stock image is pretty ugly. Took me 3 debloat attempts before I had it behaving the way I wanted it to, but before I debloated, I had some lag issues (SK Telecom... grrrhhh).
Historically, Korean carriers (much like AT&T and Verizon) love putting useless junk on the phones for "productivity" but really they are there to charge Korean users more for other services, etc.
If you haven't done so, I would root and debloat, and see how big of a difference it makes (absolutely amazing performance after debloating on my F400S).
^^^^ - Will take that into consideration.
This may be a possible fix for now, can't yet confirm
open dialer
press 3845#* INSERT THREE DIGETS OF YOUR MODEL NUMBER THE PRESS #, for example, I am the F400K, so 3845#*400#
Hardware Device Test > Touch
update touch firmware
touch firmware version
wait 10 sec
reboot
It may or may not help
EDIT: It's been a few weeks and I haven't had this issue again. Usually every 4-6 hours it used to happen after powering on the screen, but so far so good.
Tried that with 855 version, it's not working. This is REALLY depressing as i just got a new phone and from day one i'm having this problem. I just can't believe LG screwed up like this, and there's no mention of this anywhere online other than this XDA thread. I hope i don't have to root and install custom rom as this really defeats the purpose of the phone.
@deedscreen
I'm having exactly the same problem on an 850 and tried your firmware method. The version number of the firmware did not change after reboot.
ic_fw_version info
SYnaptics 5.5
PanelType 1
version: v1.22
IC_product_id[PLG313]
Touch IC : s3528(family_id = 1, fw_rev = 1)
What version is your firmware? Also, did you find out about the fix from somewhere?
I have the F400K, but just got a US T-Mobile edition, (I'll eventually switch my signature). I would honestly suggest waiting for an OTA update. Call LG so they can document this. If that touchscreen update method doesn't work, I'm not sure what to do. I found the method somewhere online, I don't recall where exactly. If someone can figure out how to side load the touch screen firmware from a working Korean model to others, that would be great. For now, keep calling LG. It won't do much at first, but at least they'll have reports of this issue.
I have (RAW) touch screen firmware version: 30 05 51 96
Same problem, but not only on lock screen
Since 5 days I have my G3 (855 Modell). I was happy the first two days, then I discovered the problem, that the device is always unlocking itself, when in my front pocket. It's because of the Knock on feature. I deactivated this now.
But since yesterday i have the same issue: three times, i was unable to unlock my phone. The touchscreen simply did not respond. I had to remove battery. Today, I read this post and tried the firmware update of the touch, but I have the impression it did not change something in the version.
After this, today I had again once time the non responding touch while unlocking and shortly after, I had the issue after ending a phone call! The touch did no longer respond and had to remove the battery again!
I hope this is not a hardware issue, otherwise I will hurry up to the seller to exchange the phone, because its only 5 days old.
This is happening when the screen is on right? Or is the screen turning off and then not turning I again?
You need to keep Knock feature on, someone already said this. That's why your screen is freezing.

Upps, yes, I just read this message now. To late: I was in the shop now and got mine exchanged. Anyway, that issue with the knock on feature should be solved also by LG: it's not acceptable, that the phone is always unlocking in my pocket.But then I wait with deactivating knock on for the moment.
So bad: such a good phone and such an annoying bug

I sold mine after a few days, i was sick with it. I disabled the knock feature through the hidden menu only to have the screen freeze every day. What, i can't use the phone the way i like? I have to face the screen outwards in my pocket and risk damaging it? Screw that...
That, plus the overheating and horrible build quality (back got scratched in my pocket) was a deal breaker for me...

Yes, indeed i also think about it. I got an official statement from support, regarding that the phone is unlocking all the time by itself in my pocket. They told me stuff like:
- this is a normal behaviour and can happen (!!)
- don't put your phone in the front pocket
- use the quick circle case to prevent...
- disable knock on (which is at least not possible over a standard setting, but only via the hidden menu).
I wrote back:
- that for me, this is not a normal behaviour
- that 90% of male users are wearing the phone in the front pocket
- that I don't like to buy a case only to prevent a bug of a premium telephone and
- finally, that they please could tell me, where and how to disable knock on
I am curious about their answer...
Good luck with that, disabling it through the settings doesn't change anything and they probably won't have a fix for months. They'll probably fix it though Android L update which will sadly come 6 months from official release at least.
Next time i purchase an Android phone i'm going with Nexus line...

So what happened? How is it doing now?
Hey everyone, I just wanted to report my results of this touchscreen bug.
Well, I've only had my D851 for a week now. Of course I rooted it the same day I received it.
I had no touch issues until after restoring apps with Titanium Backup. I'd restore all user apps, then very few system app via XML. Since I just upgraded from a Galaxy S3 T999 I limited the system apps greatly. So much in fact that I only restored 1 system app......Media Storage 4.4.4 (Playlist). THAT WAS MY SCREEN KILLER!
The media scan on my D851 would render my screen unresponsive. I could only hold the power button and click power off or restart or whatever else was on that power menu. Then the phone would reboot after minutes of of a dead screen.
I flashed back to stock and reproduced the same issue. So now I've been running this device for 3 days without any screen lockups. I just have to rebuild my playlist again LOL.
I hope this helps someone here.
Knock
If you turn off the ability to wake by knocking the screen, it causes this issue where the screen locks. Turn it back on and the problem seems to go away.
I think LG really has to deal with this issue.
Hi guys, I have red a lot about this issue but I'm still confused with my LG G3 855.
First I realize problem with unlocking the phone using double click. Tried to upgrade touch software firmware using hidden menu and the screen became almost totally unresponsive. Tried to re-flash original 5.0 and 4.4.2, factory reset, battery removed, etc. but no luck.
I'm wonder if this is a software problem or became hardware. Should I consider replacing display or problem is in motherboard?
I really don't know what to do! Appreciate any comments or suggestions!!!
Thanks in advance!

Screen not recording all touch events

I have recently received my G3 32GB (855), however, I noticed the screen is not responding to all touch screen inputs. Id say it responds 8-9 out of 10.
For the record, I'm running all stock, no root, only ART enabled.
I even went to the hidden menu to check double check if there are any faults, but it was correctly recording every time I touch the screen.
It feels like the UI is not responding sometimes...
Any suggestions?
I've noticed that today on mine as well for the first time. Double tap to unlock has been very hit or miss, even with a reboot. I'm totally stock and didn't switch to ART yet. Not too happy about this and will keep monitoring.

If your not looking closely, its easy to assume that it was due to lack of proper contact.
But when I started noticing this issue, I started paying attention to each screen touch and then I felt that I had some misses...

It was to the point that it didn't work on first double tap, didn't work on second double tap, and I slowly and methodically did it a 3rd time with no luck. Had to use the power button on the back. After a restart its only done it once since....kind of weird.
I'm not facing any knock on problems usually, it actually responds more than my G2 I have to admit.
My main problem is swiping thru the launcher.
Even inside apps I can't recall any prob, it makes me feel like it could be related to launcher lag...
I just installed Nova and I'm no longer facing any issues with the launcher not responding to certain swipes. I guess there are more optimizations required for the LG launcher ui
I am having the same issue. I did install one of BodyGuardz tempered glass screen protector. I have art and I am rooted with towelroot.

Not the solution you are looking for but, I have to say, this was the case also on my G2 and G PRO 2. It's an LG thing. Not to bad by any means but noticeable and something that should be sorted.

Maybe you're right about that, I still have my G2, but its running cloudystock 2.0 and Dorimanx Kernel v5.8, so it feels like a different beast.

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.
