Apologies in advance for the potentially vague description, but I also cannot find a solution elsewhere on the forum.
Earlier today, I was watching a YouTube video and then I locked my phone and left it to charge whilst I went downstairs (as I often do). When I returned roughly an hour later, I found the screen on, which I only ever do if I've left Draw Something open, or some similar app - but it was on the lock screen.
(none of that is necessarily important, I just wanted to clear up the "what did you do to make it start rebooting" question)
Anyway, after unlocking the phone, the screen went to black and the phone restarted.
However, it wasn't a "real" reboot, because the boot screen didn't come up, etc. It's just like just the UI is restarted. I can usually use the phone for about 30 seconds at a time. This seems extended when I have flight mode on, and is even longer still when I have the phone locked.
I've uninstalled some potentially-offending apps, removed the SD card, cleared some apps' data, but to no avail.
I'm using default 4.0.4 from Samsung. The only issues I'd had with it until now were that some apps crashed occasionally, but I attributed that mainly to the apps themselves.
The most annoying thing for me is that is seems like it's an issue that can be fixed quite simply, without having to uninstall every app or factory reset the phone.
Anyone have any other ideas as to what I could do? Thanks!

just go to recovery mode and fix permissions
Has anyone experience the second screen not working all of a sudden? Mine is just dark with the main screen both on and off. I tried toggling the second screen on and off from the setting, reboot, battery pull, and wiping cache and dalvik but so far none worked.
It's not a hardware issue, I think, because when I open the camera, the second screen comes on for the camera Settings. Also, when in twrp, the second screen is also on as a part of the whole display.
EDIT: I can actually see some light bleed from the second screen with the main screen off. It's just not displaying information it should for some reason.

I just got mine, and something I did in the course of adding/changing/modding did the same - I lost my second screen when the phone was off, but when it was on I had my shortcuts. I wound up factory resetting and re-installing/re-configuring my apps... knock on wood, everything works just fine now. I think mine failed when I unfroze an app in Titanium that it marked for me.
About the only thing that I did before I lost the second screen is installing a game from the play store. I have uninstalled it, but still no luck. I most likely will factory reset and if that doesn't work, I'll flash stock rooted rom... And set my phone up yet again.

Same symptoms
I am on stock, albeit rooted. I froze a few apps, but I have also rebooted multiple times before the second screen disappeared, so I am not sure how anything I have done this far could be the cause.
Because I saw I am not alone, I started to do some digging. It looks like the app is located in /data/data/com.lge.signboard, which actually has symlinked directories. Not sure if its a clear indicator of the issue, but most of the directories are empty. Definitely odd.
I'll load up SSHd later and see if I can investigate more.
Did the factory reset and now the second screen works. I'm sincerely hoping that this is not a regular occurrence. I haven't liked a phone so much since galaxy s2.

I also had my second screen go funky. Haven't factory reset but I'm going to. It seemed to happen as I was also defrosting and refreezing some LG things, mainly services and such and not apps that you interact with per se. At right about the same time I noticed something else strange. When plugging the phone in, it takes several seconds for it to realize it whereas before it used to be instant. Also, the camera is very slow to load and change from the front to the back ones.
So I got a little bored
And fired up adb logcat to see if I could find anything. I don't yet know if it's related or not, but there is a message
Code:
I/[SystemUI]MiniStatusBar( 5541): signBoardWindowShow() requested but unavailable. Hide MiniActivity.
that shows in the log.
I to tried clearing cache and dalvik or art or whatever to try to get the second screen back no avail.
I'm having the same issue. Any update on this?
I too am interested in this, I had this issue occur too when I froze some applications (system apps) that I didn't think were necessary. Unfortunately once you freeze the component it blocks the screen and unfreezing everything back does not bring the screen back you have to factory reset it. Any ideas of what the service is that affects the second screen?
Second Screen symlink busybox
After reading all your comments on what you could have done to cause the second screen from working, it looks like the symlink is broken especially if you have updated your busy box. I too started to have the second screen go bad on me and I couldn't figure it out until I read this thread especially the log post. I am going to reset and ensure that smart install is set right in busy box.
Recently, the AT&T LG V10 (H900) just got root here: http://forum.xda-developers.com/att-lg-v10/general/root-lg-h900-real-tot-make-tungkick-t3336317
I then debloated the V10 on firmware H90010f with Debloater v3.90 here: http://forum.xda-developers.com/android/software/debloater-remove-carrier-bloat-t2998294
Before, I decided to have the second screen off for a while, so I disabled it in the system's menu. I then advanced towards debloating. Decided to turn on the second screen again. Notice that there were issues with it. So now I'm currently experiencing this issue: the second screen does not show date, time, weather, notifications, quick icons. Only shows quick toggles if I swiped from right to left, such as sound profile, WiFi, flashlight, and camera. I undo all of the debloating, rebooted the phone many times, still the same problem. Sigh. I'm trying to avoid doing factory reset because I'm not up to reloading everything again, especially the SMS/MMS.
So, anybody found out a better solution other than doing a reset?
Update 1: It seems like re-rooting with updating the ROM with the "upgrade" option for the AT&T LG V10 to not do a full clean install does not solve the problem. I didn't lose all my personal data, but I did not gain anything that it restored system apps to previous default settings. Sigh, it's just one step closer to just do a factory data reset.
Update 2: There appears that other things were broken from disabling/removing apps (during phone calls, cannot multitask, such as switch apps or use the notification area; SuperSU couldn't generate a log correctly), so I went ahead and did a factory reset since there was no alternative restoring method. The second screen works again and so does the said apps. Looks like I'll have to be careful which apps I'll be disabling/removing with Debloater.
Uninstalling an app restored my second screen.
I had this issue as well. Camera controls were in the second screen space, the swipe to end call would appear, but none of my other settings stayed long after restarting my phone, maybe 10 min. I uninstalled some of my most recent apps, the suspect one being "Zooper Widget Pro" and the issue stopped. No factory data reset etc. This app was a launcher-type app (I'm a geek but nowhere near the tech terms used elsewhere on this site) and I thought it might be the issue due to its ability to control the home screen. I doubt it was intended to work with this arrangement. So I would look at any launchers or apps which can control the home screen before doing a reset as this exact issue was easily solved for me.
I just got the phone and set it up. the only thing I disabled was ATT bloatware nothing else. 2nd screen is only on when main one is on. Using nova launcher. I tried uninstalling and that didn't help. Is there any more info on this, can I get it working without factory reset ? I get no indication of notification right now other than sound.
I did factory reset and that didn't help either.
I have a same problem with the second screen to. So anybody can help me!
Is there anyone can help me pls!!!
I solved this problem by checking PINs on mainboard for the second Flex Cable for LCD of LG V10, see the video, READ comments here https://www.youtube.com/watch?v=hpeVAqgU94s, so in my case one of three PINs was folded little, so one PIN contact didn't touch the second Flex Cable and this caused the problem...
Hi,
Something strange happened with my z5c E5823 running stock 7.1.1. Here is the riddle
I got a message the other day, saying space on internal memory is decreasing and the option to transfer stuff to SD card. Since there were almost no pictures and music on the phone, I keep them on SD card, there was the option to transfer about 2GB of Apps. I choose that (big mistake when I think of it now) .
I continued using the phone while the transfer was in progress and @ some point , the phone crashed. That never happened before. Screen froze and stayed like that for around 10 min, completely inactive, and the phone restarted itself alone. After this it all seemed fine until I tried to start the Camera app. It just gave me black screen and some seconds later the message - Camera has stopped/ Restart app.
The front camera and flashlight don't work either.
Another weather app - AcuWeather didn't want to start too, but after reinstalling it it was alright.
There is no such option for the camera app and clearing data and restarting didn't help.
Decided I will do a Factory reset for the first time since I use the device and tried a manual back up of all the info to the SD card. Contacts , personal info and settings backed up successfully , but the process hanged up at 50% when transferring apps. It crashed and stooped. Tried it 2 times !
Since back up wasn't possible I proceeded with the factory reset and after that the phone successfully restored my personal data, without the apps , but the camera didn't work. I did a Software repair with xperia companion with the same result.
Another bug appeared. When I pull down the full notification bar, and want to edit/rearrange the icons/shortcuts and press the little pencil next to the settings(gear) icon, the phone freezes for a few seconds and than the screen turns black. The phone is unusable at that point, thought it works, and receives calls which i can not answer. I only can restart it, because the power button gets me to the window for power off and restart.
Than I read some camera sensors might get disconnected from the board so I opened the phone , but it was alright inside. nothing changed.
Now I got an open phone and no answer or clue whatsoever of how to proceed.
Any ideas are very welcome!
I there a way to reset the phone to an earlier version of android?
Thanks inadvance!
Not sure if this is the right place or not, but looking for some help.
My always on display worked fine last week when I got the phone and set it up, but now when I try to change the clock face it hangs at a blank screen for a few seconds before crashing. I've tried rebooting, clearing data and cache, disabling and re-enabling the service, and redownloading it all together all to no avail. I'm trying to avoid having to factory reset if at all possible, but I'm not sure what else to try.
Also possibly unrelated, but my file linking app also doesn't work. It crashes when it starts to upload and never progresses past 0%. Less concerned about that one though.
Messing around with one of my (5) this morning - I was trying to modify the 'hosts' files per this post by @HP_TOUCHPAD.
Tablet was acting funky, the touchscreen kept going dead & apps kept refreshing while trying to use them.
(GMail, Hangouts, RootExplorer, File Manager, etc.)
A double press of the power button would bring back the touches but the apps kept refreshing and touches would drop within a minute or two.
Went and did a wipe in recovery of Dalvik and Cache, and still no joy.
Then something occurred to me.
I've got a Touchstone setup on my desk. Keeps the tablet charged and makes for a nice stand.
Well I took the tablet off and it's been functioning fine for 30 minutes on a different stand.
Go figure. . .
Now back to the original task.
