LG G4 goes black screen and freezes after taking pictures - G4 Q&A, Help & Troubleshooting

Hello,
My LG G4 sometimes goes black screen just after taking a picture. It does not respond to any button press and if it is playing any music it just stops.
In order to turn it on again I have to remove the battery.
Is there any hardware issue related to this? Seems like I'm doomed to this, my former Nexus 4 used to do it also.

Never heard of it bit I have not been around too long. Weird that 2 of your phones do it... Some app?
Maybe try a factory reset to rule out software. Did you try different camera apps as well?

I always use the original software for the camera and both were unrooted.
I have also reset both and tried to cause it make it freeze again and both did it without any extra software installed on it.
The only difference between them is that Nexus 4 used to reboot(sometimes I could hear a buzzing coming from the auto focus system before rebooting) while LG G4 refuses to turn on again until I remove the battery.

Cannot connect to camera

When I first start the camera app after a reboot I get the message "Cannot connect to camera". If I try to start the app again it works fine every time until the next reboot.
I've tried a factory reset which worked for a few reboots until the message started happening again.
I'm running the latest stock rom and can't figure out what's changing to cause this.
Any ideas?
Had you got that problem on earlier versions of stock ROM?

Sorry, I haven't had the phone long enough to have an older version of the stock rom.
Even I had this error once, I had to reboot the device to get that fixed.
This was the 1st time it happened.
One thing is it happened while shooting a 720p Video.
I don't think it's software problem, probably camera is damaged, or its flex cable. I had the same problem for a moment after disassembling my Play but I forgot to completely connect flex to the connector.
I think the only way to fix your problem is to bring Your Play to authorized service or (if your phone has warranty) send it to SE.

It could be but it just seems odd that its only the first time using the camera after a reboot. Try the app a second time and every other time its fine.
I would have though if it was the flex cable it would be all the time or happen randomly.
Well.

I'm having an issue like that right now. However, I started getting it after I messed with a ton of system files and the framework-res.apk
Did you do the same? I'm working on figuring out what went wrong, it's definitely a software issue for me.
Possible Problem and Solution
Hey guys,
I noticed something really curious after having an extensive conversation about a few r800's and a Moto Cliq XT about camera issues and I've isolated what might be the problem that people are unknowingly creating.
Status Bar Widgets
Having the LED/Flash/whateveryouwanttocallit light as a widget toggle in Android 2.3.x seems to use the same line of code as the camera. Or something techy like that. IDK. I was about to fix it after a ton of annoying work. But the easiest way (and fastest really) that I came across was just turning the widget off. Removing it completely. In fact, just get rid of that entire feature in 2.3.x and save it for like, IDK, 3.0+
Really hope this helps that random person out there who needs it.

[Q] different volume bug, same thing or broken phone

have i got the volume bug if my phone hangs and then reboots every time i touch volume up or down when the screen is on? Samsung insist that its the same thing and i need to wait for the update but i can't see anyone else describing that the problem causes a reboot, and my volume has never actually turned down on it's own as far as i can tell.
That sounds different altogether.

Thats what i suspect. Its just a pain to have been waiting for 4 days for something that probably wont fix anything and then to have to start the whole thing over again with samsung. O well

Deal with the retailer you bought the phone from, and get a replacement from them.

I'll give it a go. Im guessing they wont do a doorstep swap like i'd get from t mobile though. Hopefully i wont be without it for long. In our short time together i've grown quite attached to this phone (and almost got used to not touching the volume button)
Couple of questions (you may have already done these -apologies if you have)
Have you tried a factory reset? If not, maybe worth trying it, could be an app doing wierd things.
Also, try running a logcat trace when replicating the issue - see if it helps point in the direction of the issue.
Does the phone still crash when you're in the bootloader? (This _may_ help to rule out application related issues)
I have tried a factory reset. Weird thing is that im pretty sure that it didnt do it for the first few hours that i was playing with it. It was just at the point that i had it all set up that i first noticed it so assumed it was a rouge app and did a factory reset. When it rebooted i signed in and hit volume and it crashed so its definately not an app.
I almost believed that it was the normal volume bug because if i go somewhere more remote in the house, away from all electrical stuff, i can hammer at the buttons for a while before it crashes so maybe ive just got a more extreme version of the bug. Just noone else seems to have anything close. Volume control works fine in a call and when the screen is off but i havent tried in bootloader yet. I'll give it a go

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.

That was not his point.....to Find the app that is causing it go one by one uninstalling until you find it.... Something probably to do with app and the screen

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!

LG G4 Touch Screen issues. Ghost Touches?

I've been able to replicate this issue on my G4 (815T Australian model) on a daily basis, just on the instagram app though.
I recorded a video of it. Slowmo part shows the issue
https://goo.gl/photos/F823e125PQckCPLp6
The screen seems confused and it just scrolls the other way even if my thumb wasn't touching the screen.
Factory data reset did not fix anything.
Are you able to replicate this LG G4 owners?
I don't use Instagram, so can't help with that app, sorry.
But if you go into Developer Options, and turn on "Show touch data", it might help add some more info to the discussion. It will show a trace on the screen of what the phone's touchscreen interpreted from your last tap/swipe.
It would presumably show a swipe up, and then back down, when you're getting these ghost touches that change the scroll direction. But perhaps it could also help show if swipes are interpreted the same way in other apps. It might help you learn a little more about what the phone is seeing, at least.
Thanks for the video and everything but why a new thread? Plenty of videos on the main thread.
Is another thread really necessary?

Might be, because this only happens with IG. I've got the exact same problem, only with IG and its very annoying.

You can try to change the touch feedback time from short to medium under settings/accessibility/motor & cogination. This will reduce the touch feedback time. Give it a try, and see if it gets better.

Well this problem is only related to the LG G4 and IG for me...I don't have any other touchscreen problems with this phone. So for me I guess this is not hardware related. During the day I just had 2 small "ghost touches", way better than before. Will see how it goes the next few days...
Edit :
after a view days, it looks like it didn't solve this issue. Today I notice the ghost touches were there again in IG
Force GPU rendening under Developer options somewhat helped.
The new v10f on my Australian G4 didn't fix the issue as well.
Any updates on this? I had same issue. N this is a replacement unit after 2.5 weeks of waiting
Just day one and this ghost touch come up.
I also have this problem
Did you solve the problem?
I am facing similar issue.between...i am not using ig.
I've had this issue as well (not just IG) and sent the phone back for servicing. It was sent back to me with a report showing that they'd done a few things but the problem is still there. I'd been thinking I'd send it back in once more and ask them to have another look. I'm getting ghost touches everywhere and quite a bit, it's very annoying.
Someone mentioned there was another, large thread about this issue but I can't seem to find it, can anyone point me to it?
Hi, I posted this in a new thread yesterday as I couldn't find anything. Never thought to search for 'ghost taps' duh.
Every now and then when just doing normal things on the my phone it totally freaks out and all by it self it suddenly starts to tap random parts of the desktop, slides the pages, opens apps, closes apps, goes into calculator and a bunch of buttons are pressed randomly. It's almost like someone has hacked my phone and is trolling me by just tapping randomly on the phone.
Just today when looking at Facebook it closed the app, scrolled down notifications, data was turned off and wifi turned on.
I thought it might have been my screeen protector, bit of moisture in it or something. Took that off and still does it. Took out the battery for a minute and still does it.
It happened a few months ago then nothing for ages and now it's started again this weekend.
Thought it might have been only when connected to data but has now done it when offline.
Any one got a solution? Does a custom rom fix?

G4 H815L Freezes on calls and hang up

Hello there,
I've searched this problem over google for several times now, with no results hitting the problem i seem to have.
In depth, the problem is so:
Whilst in a call, after t (a certain amount of time which is not fixed) time (it can be seconds or minutes), I suddenly stop hearing the other person, and the phone won't respond to any attempts of hanging up myself. after a few more seconds frozen there's a *pwahh* sound and it hangs up.
any ideas what could this be?

Hi Almog,
I live in Israel also and have LG G4 H815L also.
I don't have the problem you mentioned.
Maybe the problem is with your cellular carrier. Try to insert different SIM card (from different carrier) and see if the problem continues, if yes, try to factory reset your phone.

first of all when did this problem started?(played with the theme on your phone ?changed icon pack? after you installed certain app? updated software?changed battery(not from the 2 you got with the phone) ? changed you screen protector lately? switched network?played with the dialer settings?did you update any application?changed any thing?)
basically if you dont think you have done any of the above just do factory reset...but before you do that download cpu z make sure all of the 6 cores are up and that the clock speed is 384 Mhz - 1.82Ghz if it does not show that you probably have a problem with the motherboard..(although you can still have a problem even if it does show its not an official indicator lol)
some of those thing might sound stupid but...when it started is the key to this.
honestly i would start with place the original battery than check if i have the correct network settings than cpu z than roll back anything i touched to default(settings and theme) than check if i disabled any app/service that might be needed than shut down background applications (1 by 1 ) after that uninstalling applications(1 by 1) after that factory reset after that take off the screen protector(which he might be even a little over the proximity sensor and than it will make the phone go crazy) and than send it to LG to fix it.

well, i obviously changed things on my phone if change means to download an app and update it once in a while..
i've tried to switch SIMs with a friend who's using a different carrier and it didn't happen, although today it didn't happen.. i'll try getting a new SIM card, and if that doesn't work i'll try factory reset, and if THAT doesn't work than i'll send it to LG.
the hussle of checking each individual setting change is to damn big.

i just hate factory reset ,because when you think you got all the apps you had installed suddenly when you need an app the most you realize that you forgot to reinstall it. lol
i know you can backup your apps but i always forget to do that.
but you are right , check individual app could be frustrating, but you can eliminate default apps or common apps such as facebook or whatsapp and such because if they were the source to the problem they will probably fix it in a day or two and you would see more people complaining about it.
