Ok, so I have a rooted Vibrant on stock firmware and I've been having a problem with my screen becoming unresponsive. It originally happened on a smaller level when the phone was newer and unrooted, however the problem has gotten much worse. I've done a factory reset of the phone along with a nandroid backup of it before the problem was severe, yet it comes back just as strong.
I already went through the problems with the no wake from setcpu, even thought it was my lock screen becoming unresponsive until I disabled it with NoLock. Also, I have the Logcat live wallpaper, and usually when you tap the screen, you can see the system processing the information, however when the problem occurs there is no response on the logcat live wallpaper. The phone doesn't freeze at all though. All the soft keys still work perfect as do the volume and power buttons.
Any ideas, tips, suggestions that might help me narrow down this problem? Could it be from a bad version of busybox? Autokiller maybe? I have it set to strict(was previously on aggressive) but no change. Maybe Autostarts is causing something to freeze up. Thanks for any help. Seams like these phones have alot of wake up issues.
I would reflash back to stock with Odin and see what happens when you don't have task killer, set CPU, etc. Also, be careful with autostarts
So I removed Autostarts and rebooted, same deal. I did a factory reset and still the same. I just unrooted a few minutes ago and the problem seams to have gone away. I'm gonna leave it like this for a bit without installing any apps and see what happens. Is it possoble I have a bad root.zip file or bad version of busybox? Doesn't make sense to happen when I have root, then go away when I don't. Any reason it could cause this? I'm really close to sending the phone back, but don't want to waste my time if it's just a bad root file or user error.
Well I don't know for a fact, hopefully someone more knowledgeable can chime in. Maybe when you are unrooted, changes made by autostarts no longer have the permissions to affect anything. Personally I would use Odin (have done it twice already) and start from scratch. But then you risk accidentally screwing up the phone if something goes wrong.
I removed Autostarts and rebooted just to make sure the changes took effect though. Even did a factory reset. Those removed all apps that required root access and the problem was still so bad it took me an hour to get the screen responsive again. Once I did get into my phone I booted into recover and unrooted. Restared the phone and now the issue seams to have gone away. Touch screen is very responsive now which leads me to believe it was something that had to do with the root file i'm flashing, or possibly busybox. Very very strange.
Hopefully someone much smarter than me could give some insight as to what could potentially cause the touch screens to just stop recieving signal. It's just bizarre that the phone continues to run fine, just not the screen.
My P7510 started to do a strange thing.
I usually never turn off the device and I just let it in sleep mode with everything off to save battery (wifi, bluetooth, ...)
Lately I noticed that sometimes the screen turns on and off by itself every few minutes.
No physical harm has ever been done to the tab and the power button doesn't seem to be sticky, so I think it may be some kind of malware.
I'm just asking what do you guys think could cause this before going with the trouble of doing a factory reset.
btw i'm on rooted stock ics rom.
thanks
Have you installed any sort of app that has permissions to wake the device or turn on/keep the screen on when running? Try uninstalling a couple of recent apps to see if one of them is the culprit.
I posted this in the A500 forum as well, but it's probable that this is not a problem limited to my device, and it's also possible that there is a rom that might help me out.
I purchased my tablet on the day it came out, so it's long out of warranty. Everything has been fine with it until three nights ago.
I woke up in the morning to a crashed app alert. I don't get crashed apps often, but it does happen, so I hit ok. A few seconds later I was inundated with crashed app alerts. At that point, any app I opened would also crash immediately. Figuring a good reset would fix it, I turned it off...and it wouldn't turn back on.
I did finally get it to start by holding the volume up and power button.
But that didn't fix the problem. I've discovered that it is somewhat stable if I keep wifi off, but if wifi is on, within minutes everything starts to crash again.
I tried uninstalling some of the apps that crash, but when I restart, the apps are back. It doesn't matter what I uninstall, when I restart, it's back. Installed apps also disappear, the wallpaper resets...basically nothing I do sticks once I restart. I tried to factory reset using the button combination required for my device, and the screen gives the "erasing user data" message, but when it loads up, everything is just as I left it. I tried using the android os option to factory reset, but when I hit "erase everything", the button depresses, but nothing happens.
So obviously, I'm a bit perplexed.
I've never rooted it, and I ran an anti-virus scan a few hours before this all happened and it came up clean.
Anyone ever experienced this? Any advice? If no one has any ideas one how to fix it, is there a way to bypass the main os completely with a rom? I have absolutely no idea how those work, so it may be obvious that it won't, but I figured I'd check.
Thanks in advance! And thanks for reading this far, even if you have no advice!
Hi,
I'm looking for some general advice and troubleshooting for my phone's issues. My phone started crashing very often, sometimes at complete random, as well as when I was using it fairly heavily (any app that froze my phone for a second before loading before the crashing would now crash my phone). Sometimes it would reboot fine, other times it would bootloop once or twice before reloading fine. I previously tried doing a factory reset, removing my external microSD card, and updating everything via Kies and nothing worked.
I got bored and rooted my phone, did a full wipe, and flashed the latest Infamous update. The problem was still there but it wouldn't crash as often while using it because my phone could handle higher app activity but it's still there. Oddly enough, after flashing Infamous, it often fails to reboot and so I have to do a battery pull before turning it back on, otherwise it won't even vibrate after holding the power button.
I'm just wondering if you guys have any idea what the issue could be. Is it likely still something I can fix? Is this potentially a battery issue or is it a hardware issue?
Thanks so much!

So when your phone have become unstable , in what condition it was ? did you ever flash it before ... so my s2x did the same thing afer a update with odin on 4.2 ... so i have reflashed it and evrything was working good after
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...
