Hello all and thanks to anyone reading this. I'll try to keep it short.
My friend asked me to replace the broken touch screen on his Optimus phone. I ordered a third party replacement touch screen from ebay and whilst replacing it I managed to crack the LCD screen. Which, as it turns out, is quite sensible. So I ordered a replacement LCD screen from ebay (another third party product) and now this is what happens:
1. the device turns on nicely, vibrates, I get the LG logo and about 60 seconds later the device emanates some sound (supposedly welcoming the user to the "desktop") but then the screen goes (stays) black without the LG logo. I can see the background lighting and the two keys have their background lighting on, but that's about it.
2. while connected to the PC, the device is recognized as a P700 phone, can't access files though. I presume due to being unable to switch the USB mode. From time to time, while left connected, the device will vibrate with no visible change on any of the background lighting.
3. things I have tried:
a) starting the phone in "recovery" by having the volume up key pressed up while plugging the USB cable. Tried this both with and without the battery. No discernible changes occurred. I assume this would work only when a recovery image is installed, which this phone doesn't have.
b) tried to perform a "hard reset" by holding the power and volume down key at the same time and then tapping the menu key when the phone vibrated and soon thereafter releasing the power and volume down key. No change.
4. things I presume/ask:
a) the LCD screen is obviously working OK, since the LG logo is shown. However, there may be a possibility that a "lower" video mode is used during bootup which works, but when the phone tries to go to "full" mode and it fails. Don't know how these things work on mobiles, really. Seen similar stuff happen on PCs so I'm not really certain the screen is fully functional, compatible etc.
b) the touch screen, I have no idea at this point whether it's working correctly or not, is it compatible etc. Could an incompatible screen/touch cause something like this?
c) if I assume the screen and touch are OK, then it must be a software problem. However, is there an option to have this device flashed with a stock ROM without having the option to turn on USB debugging?
Currently, I have no idea which firmware version the phone is using. To the best of my knowledge, the phone isn't rooted since the previous owner had it just for a while and when the touch screen broke he handed it over to my friend and that's how this mess started. Honestly, if someone payed me to do this (which I wouldn't even accept due to being inept at such matters) I'd just reimburse them, scrap the phone and take this thorn out of my posterior. However, with people you know and have decent relations with it's hard to settle such matters so I'd really like to repair this little phone.
Previously I have managed to change roms on some of my phones (T-Mobile Pulse, xperia Ray; without actually bricking anything) so I have a general idea on how these things work, but this issue is well over my head and therefore any advice would/will be greeted with a giant gaping smile on my face.
To end with a fitting quote: "Favor gonna kill you faster than a bullet".

you may have moved a chip of sorts or didnt insert the touch correctly.
i use to have a huawei u8110.
It once started having boot loops, when i opened it i saw that a chip was not correctly inserted in its socket.
So you may have moved a chip or just didnt insert the screen correctly.

OK, thanks. I'll certainly try to reassemble it. I guess all that's really needed is to unplug and reconnect everything?
OK, I tried reconnecting everything. Some of these connectors are a bit finicky, but I think they all sat just right, clicked into place and seem leveled. No dice.

A hardware problem does inflict software problems, my guess is. The screen is not an original LG screen. Witch may be the main source of the problem.

only thing you can do now is try to find an original screen for the phone and install it.

Well, if I had one of those laying around it would have been the first thing I tried. But this is a really low cost phone throwing even more money at it doesn't seem like the right thing to do. Especially since there aren't any guarantees replacing the screen would fix the problem.

That is true, its really not a bad device once you mod it up a bit, but it is a low cost device now.

I did download some kdz related files, probably from some thread on xda. I'll try seeing if I can do anything with it.
I have followed this procedure http://forum.xda-developers.com/showthread.php?t=1060121

The phone is (sometimes) recognized in the device manager, however it doesn't appear to be detected currently.
Edit2:
Now the phone is detected as an "LG P700" in the device manager, even though it's marked as if it has some problem. Tried rerunning the KDZ update tool and something is happening! LMAO will let you know. The screen has turned in a nice shade of green, apparently the emergency mode.
I left it for a few minutes, the updater has "finished" shown in the log window, but then the updater tool crashes. No change on the phone, sadly. Tried repeating it, no dice. I think the tune which is played upon failed bootup has changed.

no nothing is wrong, updater tool always crashes when kdz is finished, i forgot to mention, when kdz is done it automatically creates a boot loop, thats not an error. Power off the device. Hold vol up and vol down and menu. Connect to your charger. Do a factory reset and the phone will boot normally

Here's the full story.
The first time i encountered the problem was when i was done using Froyo from the Android thread (works perfectly btw). I restarted the device via the button on the back like i've done a hundred times but this time it vibrated and nothing showed on screen.
I figured it was some random fluke - i yanked out the battery, put it back in and powered the phone - everything was fine so i didn't think anything of it.
Two days after that i picked up my phone from my desk and tried to turn on the screen but nothing happened, thinking it was stuck somehow i rested via the button - this time it didn't vibrate and it didn't turn on. I tried a couple more times to restart it - nothing. I pulled the battery and tried to turn it on via the power button - nothing. After three tries of pulling the battery and pressing the power button it vibrated but the screen didn't turn on, i left it like that for a minute and i heard the startup sound from my ROM (Energy's from july 1th).
I pulled the battery again and tried again - this time it turned on vibrated and i saw the smart mobility screen after it booted into WinMo i noticed that the wi-fi was turned on, so while i was mashing the screen i must've activated it. This leads me to speculate that WinMo was powered on and the touchscreen was registering input. I set it down trying to think what the problem can be and turned off the screen - it went to complete black first (noticed it due to being in total darkness) and then turned off - couldn't get it to turn on so I again restarted - it vibrated again, but again no smart mobility screen, the startup sound came and i pressed the power button - that turned on the screen and everything was fine.
Frustrated i performed a hard reset but that didn't help - again the screen wasn't powered on.
A couple of more hard resets later i decided to do a task29.
After the task29 i flashed Energy's 8th july ROM, but the problem is still there. (After flashing i couldn't power it on for a while).
So to sum up:
- from time to time no screen
- did a hard reset and a task 29
- i have access to the bootloader and it loads every time (the screen turns on every time)
So due to the fact that the bootloader turns on the screen every time i think that i can rule out a hardware problem with the screen, but i did a task29 and flashed a new rom so it shouldn't be anything software related either...
The phone works after a while and is fully functional but the problem happens from time to time (i haven't installed any additional software to eliminate interference).
What do you guys think?
I've been doing some testing and the "blackout" presents itself at random.
If i leave the phone on after a while it blacks out when i press the power button the screen stays off but the button at the bottom work, also the volume buttons change the volume and i can hear the sound. If i leave it for a while and try again the screen does turn on. I can't figure out why and what causes it to do that...
One time that it did boot up properly there was this message

I noticed that i had a Microp at the bootloader screen. Does anyone know what it is and why it's tormenting me?
Also while the phone is charging and the led light is on and the phone goes in black out "mode" the light doesn't go off after i unplug it even after it goes out of blackout mode. Maybe that's a clue.
I'm stuck and have no ideas...

i think microp stands for microphone
update it?
don't where from but will post if i find it or someone else migt be able to find it.
another problem is how are you going to install it for that i do not know unless the phone still operates then you can install it by cab if not maybe it can be cooked into one of the new roms.
hope you get your phone running again soon!

Sorry for re-bumping an old thread, but I think my phone may be doing something similar.
Did you manage to get it going OP?
My phone has worked fine since I got it (a year or so ago) - but just lately it has been a complete a**e to boot up. I was using the BSHenge ROM (USPL) when the problem started and my phone randomly froze, leaving no alternative but to reset it. After the reset I either get a black screen only, or the initial boot screen "Smart Mobile" with the ROM version in the bottom right corner eventually appearing. Then it hangs.
I did a hard reset, installed the latest NRG ROM and my problems seemed to get worse, I persisted resetting and yanking the battery and eventually it did boot, but froze when trying to do various basic tasks.
I've sort of got it working by hard resetting again, choosing the latest BSHenge ROM and re-flashing... It's still really slow on boot up but does seem to get there... I haven't dared put my storage card back in yet - I intend to back it up and re-format it... I just get the sinking feeling that this problem is getting progressing stil and is possibly hardware?
I don't know what a task 29 is, so I don't think I've done one of those - I've done a hard reset (power and vol-up to boot), and I'm pretty well versed using the USPL and flashing the ROM.
hi.. i've had my hd2 for a while, everythings worked fine.. today it stopped working. i run android and the screen started freezing on wakeup from standby. i tried a different build and when i press and hold power to turn off the phone completely or reboot, the screen freezes and i can't click turn off. the same thing happens in windows mobile (i've tried several different roms, even the stock one). everything works fine, but when i hold power to turn off the device, the menu pops up but i cant click anything and everything freezes so i have to pull the battery. any suggestions as to what the problem is? is it a hardware problem? thank you..
edit: actually, i dont even have to press anything. the phone works perfectly fine until it goes into standby. i cant get it out of standby, it just freezes at the lockscreen. is it a hardware problem?

This was a common error for me in the past. I solved it by:
HSPL3 (2.08)
Task29
Flashed latest radio (_14)
Flashed new, titanium winmo ROM
Backed up then reformatted my microSD card
Installed a fresh desire hd-based Android from mdeejay
Turned off "Live Wallpaper"
Installed "Advanced Task Killer" (by ReChild in the Market)
Set ATK to kill all but white-listed apps when the screen turned off
Installed "Overclock Widget" (by Billy Cui in the Market)
Set my overclock to 1200, screen off clock to minimum
Also, make sure that your microSD card isn't falling down and going into "read-only" mode. This happened to me and I had to replace the card
Hope this helps!

I had exact same issue... it is a hardware issue with the button chasis/ digitizer or motherboard. Call up HTC directly and most likely phone should still me under warranty.
This happened to my previous hd2, but not before i tried Android. never tried it on this one, hasn't happened.

Absolutely nothing to do with android, You just happen to be using it at the time.
You have/had defective hardware its as simple as that.
It's the digitalizer my good man, I just had my phone replaced because of it. I had the same symptoms you describe when the phone comes out of standby the touchscreen is paperweight.
I've been running Android for a few months now with no problems, a few weeks ago my touch screen locked up and I couldn't unlock the phone for a couple of hours. later that day everything worked great, untill today. The screen locked up again, so I pulled the battery, but now when it asks if I want to boot into Android, i can't push yes. I've tried more than a few times, hoping to get lucky. A previous post says it's a hardware issue. Do i need to revert back to windows to get it fixed? Can I revert without the use of the touchscreen?
I had the same problem. I would use the phone, then keylock it and put it away. later take it out, press the red button and the screen would turn on, but couldnt slide the unlock bar. Had to pull the battery out and restart it. It would always work fine until i press the red button to turn the screen off, then the same thing.
I took it to the shop i bought it from here in China and they basically told me to F**k off! I ended up going to Taiwan and getting the motherboard, screen and buttons replaced.
Even now its not quite right as when i press the red button to turn the screen off, its as if i pressed it twice. The screen turns off then quickly on again. Other times i press the red button and its as if i never pressed it. Phone doesnt crash, everything is working, just as if i never pressed the red button. Its definatly the phone as i have tried 4 different windows and 2 different Android versions.
Hi. So yeah I figured it was a hardware problem. It wouldn't freeze if I turned it on from standby using any key besides the red end call button. But if I turned it on using the end call button the screen would turn on but it would freeze. I called up T-Mobile and got a replacement. HTC offered a replacement too but they were gonna take 2 weeks so I went with T-Mobile. Hopefully this helps anyone else who has this problem. HTC will replace it. Thanks for everyone's help

Same issue here, called up tmobile. Will be receiving a new or "like new" unit next week.
Dear, I had the same issue today, but finally I found some people said it is becacue of the electrostatic problem, the problem cuased by the PC/laptop Power Cable is not connected to the earth.
The solution is just opening a cigerate ligher or even touching the water piple can solve this.
I did solve it.

This is exactly what is happening to me now it is rly driving me mad, how does a cigarette lighter help this?
edit: First i have tried installing a new build and that didn't work, after that i did task29 and fresh install at first it was the same. The strange thing was sometimes when i turn the screen on with back button it would start working, as if it didn't want to work any other button. This is where i lost any hope i just started randomly putting metal coins on the screen, touching pipes radiators and at the end somehow it started working. I was like wtf this is beyond strange, how can someone make this infernal device.
What about using a wall charger? Still no ground? I used both computer and wall charger but the problem remained. If my new unit messes up ill try the car lighter

The dreaded brick, perhaps one of the more overused terms when it comes to the galaxy s. By all accounts the SGS is one of the most difficult phones to actually brick.
As Shantzu put it:
Bricked: The term "bricking" should only be used in the case where you get your phone in a state where it is inoperable AND you can not in any way repair it yourself.
In many cases your phone is not bricked. Common uses of the phrase bricked often include:
1. Boot looping
Try option a, b or c2. Not going past SGS logo
Try option a, b, or c3. BSOD (Black Screen Of Death) logo

Try option d
In most circumstances your phone is still recoverable. Have a look below to see what you can do.
Options:
a. If you have the 3 button combo available then try the the download mode combo (Volume Down + Home + Power). If the phone is displaying the BSOD logo and you hold this combo for 10 seconds or so, with the USB plug in, you might just be able to get it into download mode (if you're lucky). If you get the charge screen, turn off phone and try again without USB plug in.
b. You can make this or buy one on ebay. It will set you back up to $10. Once you have the jig, have the phone off, plug it in and it should boot into download mode.
c. Use android debug bridge. There is a useful guide on how to get it working and how to use it to put phone in download mode here. This will only work if your PC is registering the phone as plugged in.
d. Use TechKidTarek's method here to restore correct booting.
If the above options do work, then what you need to do next is get odin up and running and flash with an appropriate firmware. There are a lot of straight forward guides out there if you don't know how to do this properly (which might be how you bricked your phone in the first place).
I suggest you follow one such as this very closely. And, for the love of android, do not interrupt the flash process. This is the most likely way to make a $500 paperweight.
When all else fails, you may have to send it to samsung repair.
Last of all, good luck.
Excellent, important guide to deal with basic problems. Should be stickied.
Excellent help
yes, should be made a stickie but
a. If you have the 3 button combo available then try the the download mode combo (Volume Down + Home + Power). If the phone is displaying the CE logo and you hold this combo for 10 seconds or so, with the USB plug in, you might just be able to get it into download mode (if you're lucky).

Another good trick to get into Download Mode is to pull the battery, hold in the two volume buttons and reinsert the battery. This may need the phone to be connected to the computer though.
Spent a month thinking mines was well and truly bricked as nothing else worked, and tried this randomly one day after work.

Now that's one I haven't heard before. I will test it myself first and then if it works for me I will put it up to see if other people have luck. Thanks a heap for this.

Tried several times but could not replicate (note: my phone is not currently bricked). Tested with USB in and out. Cannot replicate the response. Perhaps you were just really lucky?
Maybe others might have some luck?
Thanks for the info although I know the repair options by heart already. A while ago I tried to brick my 'old' S1, to see if I could fix it again, just for the fun of it (I've done worse when bored). I assumed it would brick by pulling the battery while flashing but it just wouldn't work. I bet the S2 is just as tough. Not going to try it though (yet)...
This could prove useful sometime... But I hope I won't need it
Thanks ... very usefull guide
Good guide. Congrats !
nice. been looking for this.
noted, thanks for the info
helped,thx
The info here saved my wife's phone, and I expect out marriage as well - she had one of those SGSes where you can neither enter recovery nor download, and I stupidly assumed you could :/ ...and semi-bricked the phone during superoneclick root (stuck in a boootloop on the S logo).
Anyway, info from here allowed me to first restore the three keys combo, and then flash Darky's. Thanks, guys!

Thanks! Saved my phone a couple times now!
I have the BSOD and NONE of the methods presented in this thread have worked so far.
Any other ideas folks?.............

Did you try the last method? Send to samsung repair.
Really good info here.
I have "semi bricked" my SGS a few times now, and I will agree that it is very hard to kill one of these things
Odin is a life saver - with that and a stock ROM I've always been able to start again after experimenting.
Hello all. First let me state that I rather not make a thread to ask help on a problem that seems to have happened to a few owners, but my knowledge as to how I could resolve the issue is severely lacking..
At some point today my phone was ringing but the screen would not show. I thought about taking the battery out and turning it back on but there would be no HTC, Bootanimation, anything. It was Just a black-lit screen which responds due to tactile feedback and the four touchkeys light up as usual. At first there was an odd sound that would play after a few minutes so I decided to charge it but again there was nothing. Even tried to access bootloader with -Vol and Power still no screen.
I asked a friend of mine to call my phone to see if it would ring but they said it instantly goes to voicemail as if my phone was off. Note that I WAS SURE IT WAS ON.
Adb seems to work with it as it seems whatever I need to do I have to do it through there.
G2 rooted with gfree method
CM7.1 RC1
Clockwork Recovery
Again i am sorry if I bothered those with posting something others would think is "too common of a problem" as I have no experience in fixing this issue. Plus I would like to try any option available as I would not like to try and have my phone replaced (because of the risk of discovering root and obtaining a G2 with stock gingerbread which is currently not rootable)
Please help..
It sounds like you're suffering from some sort of hardware failure. You need to send your phone in for repair/replacement.

Same issue here...
I'm facing the same issue, when i try to unlock the phone (power button or trackpad) the screen lights but stays black, and the buttons are also backlit. I have to lock again with power button and unlock again to get to the actual screen.
It first happened a few days ago, and since i didn't reboot/restart in weeks i tried to reboot but the same issue comes back.
then i shut it down, pulled the battery and then back, and restarted: the phone goes directly to that black backlit screen, i tried several times and tried recovery with no luck, so i thought my phone was messed up although i did have some haptic feedback, well in fact the phone was actually booting, but just not showing anything else than the backlit screen; i waited a minute or so to the booting completes (still shows nothing), then i lock/unlock the screen again and there it is, asking for the pin code.
I tried to go to the recovery again to try to wipe dalvik-cache, i know for sure it goes to recovery, but with a totally black screen, not even backlit this time; the trackpad is too sensitive in the recovery to just blindly navigate in the menu, so it is not useable at all.
Then i had the idea to go to Rom Manager, i reflashed the rom from my sd-card, and enabling wipe dalvik-cache, which worked (all through a black screen). After a few minutes i "felt" it rebooting (vibrating) but still back to that black backlit screen, and i locked/unlocked it again and back it was asking pin code...
I also tried to roll back recovery to 3.0.2.4, since i remember i updated it a few weeks ago, but still the same issue.
I don't know what else to do without accessing the recovery, i wanted to try another kernel, or remove the trackpad wake... is there a way to do it via a script? I guess it's what Rom manager does...
Next step will be a total wipe, but i need to make some room on my sdcard for backup purposes first...
If anyone has an idea to sort this out, i'm highly interested...
I'll try to get a logcat, maybe could give a hint
Edit: Virtuous sense 2.0.0 (used it with no issue since it came out, could it be a hw issue?)
Edit2 : attached logcat
Is the pin screen differant than the usual one ie white number keys? If it is that's the sim lock screen you need to call the carrier to get the code or find out the default. Or just get a new sim lol
nah it's the 4 digit pin code, i didn't lose it btw, it's still working and i can use the phone, but i have a black backlit screen whenever i want to wake the phone, and thus when i receive a phone call, i don't know who it is and i blindly press/swipe the screen to answer, because if i want to use the same trick of locking /unlocking, it doesnt work as the lock button is also used to reject a call...
Maybe rip and reinstall the phone app?

I have the same exact problem as this EXCEPT, it's intermittent. Sometimes when I wake the phone I get an all black but backlight screen, and other times it's fine. I'm on CM7.1.
But a superwipe and reflash will probably fix it. Also don't restore system data on TB
I know i still can use wipe data + cache + dalvik through rom manager, and i always used to superwipe before switching roms, but how can i do that now when the recovery is all blacked out?
can anyone guide me to a script or something i could do while the phone is active, to tell him to reboot to recovery and flash that superwipe?
anyway i'll try the regular wipe and keep the thread updated

On my side if i leave the phone locked more than 30 seconds, it happens 100% of the time; also I noticed that now the backlight blinks 2 or 3 times (1 second blinking) when locked, first a few minutes after locking, and then randomly, about 3 or 4 times per hour; I guess it's getting worse;
I've read on another thread that it could be video cable getting loose, but since mine is still under guarantee, i won't open it right now just to check, if i can't fix by wiping / superwiping (when i know how to), i'll use that guarantee, which is one month left (lucky me)
EDIT: one other thing that makes me think it's no hardware, when the black screen appears because of a phone call or a message, the ringtone and notification sound are both half as loud as they should be, this is all really strange
after backing up my data, i reflashed the rom via Rom Manager, and I wiped data and cache (which equals to factory reset) this time: the first screen that should show the pin code numpad was already a black (backlit) screen!!
Also, thinking about it, i realised that the "flash rom from sdcard" menu in Rom Manager is in fact "Flash ZIP from sdcard": the zip doesn't have to be a ROM!!
So I tried flashing a new kernel this way, also some framework modifications (extended settings, removed TP wake, etc...) they all install Ok, but still this black screen...
Also I was about to flash SuperWipeG2.zip this way, but if it doesn't fix my problem, I will be stuck with a blacked out recovery, as SuperWipe wipes everything including /system; so if anyone has an idea to tell Rom Manager to flash two zips (Superwipe then Rom) i'll be willing to try, or a script to do that;
Maybe i'll have a look of the scripts in Superwipe and in the rom, and put both zips together... don't know if it's possible?
Maybe I'll try the Superwipe alone if I can get a spare phone, just in case...
Other thing:I used the phone's gps for more than 5 hours with the screen lit, and it never flickered even once; so it's hard to believe it's a screen connection issue...
Just to keep this updated, everything i did, including superwipe didn't change this issue, so i sent it back to the technical support (under guarantee) and I got it back today; the report that came with it says the screen has been replaced; so it was hardware finally...
Hi, i have same problem.. Black screen in recovery and during the boot. When the system boots, screen is OK. Sometimes i have also blackscreen when I want to use HW keyboard. I tried 4ext, reflash older versions of CW but still the same. I can see a screen through Android Screen Monitor and I can cotrol it. But phone is blak, only backlight. Can somebody say, how to solve this issue?
So, for other, if you cant see screen, you can use Android Screen Monitor for Windows and connect phone through USB and see a screen.

WAIT one minute... they don't care? where was I when this meeting took place?
I had this issue as well on a spare G2 I had.
The screen was just black but you could tell it was lit, hardware keys were lit as well.
The phone was actually my brothers and it rooted w/ CM7.
I ended up selling the phone as is on Ebay but after some research it was a failure in the hardware for the screen and I found extensive instructions on how to replace it that I didn't wish to do.
I never attempted to get it replaced and kind of wish I did now if they don't care about the device being rooted.
I purchased my G2 before he had his, and it's never had the issue so not sure what to think of it.

I used the same tutorial to change the LCD but after I put the new its just the backlight but nothing else... I will give it another go maybe and have a look again at those ribbon cables! I guess...
---------- Post added at 10:59 AM ---------- Previous post was at 10:09 AM ----------
I found on ebay: HTC-Desire-Z-T-Mobile-G2-A7272-Slide-Flex-Cable-Ribbon
or I found also with the chassis for a bit more.
Thinking to buy this, it would be great if anyone could confirm that it would help "my condition" ?
THanks in advance!
In terms of cables, yes the flex cables are what you want.

Hello all,
Today I stumbled onto something that is rather annoying. As I was tweaking which apps I'd like disabled, I noticed that the "Check Battery" box pops up on every reboot, especially if I don't immediately unlock my phone. Because I never noticed before, I thought it was all the tweaking I did so I re-enabled everything. It still continues to show though, so I decided to factory reset. It still continues to show!
Now, when you first buy the GS5. If you remember, upon every reboot, you will be welcomed with a "make sure to check battery cover" until the third message, which allows you to disable the dialog all together.
Now, this is where my problem exists(perhaps even yours as well). Reboot your GS5. Do not unlock it when it starts up. Let the phone shut off the screen(default is 30 seconds). Wake the phone and unlock\swipe to go into your home screen. You should see a glimpse of the picture attached. It happens very fast, but it is clearly visible.
Funny thing is... if you reboot the phone, log in immediately after, there is no problem with this quick dialog pop up at all. I mean, it isn't really a problem to begin with. I would just like to know if its faulty software or my GS5.
Thanks in advance,
Dominick
No one? Oh man, I'll definitely be heading to the Verizon store later... lol

p.
It's that the notice on cover not tight? To let you know that it's not water safe?
Yes. I believe this one is referring to the battery covery. It's closed. It's tightly closed. The message appears so fast I had to slow motion a video to obtain the picture I've provided above. It doesn't happen every reboot. It only happens when I reboot, let the phone turn off screen, and then unlock it. I'll see a glimpse of that message and it closes automatically.

Okay so I had some time and made it down to the Verizon store. I can replicate the problem with ease. I know most of the average phone users will probably never notice, but I think I can confidently say that this is a software glitch on all of our GS5's. lol

This is normal. I get the warning everytime I reboot my phone. This is just a warning, even if your cover is tight. You can check the option do not show this again to get rid of the warning.
Also a trick you can do to take a screencap of your phone is to press and hold home and power at the same time.

You know what, I've noticed this too.
It's quite fast. It's probably the same message box that comes up, and since I've checked to not see the message again, it comes up and then disappears. You have to be very quick to catch it.
yea n there is another one that says to make sure the battery door is closed properly where you plug the micro usb in to.. its to make sure its properly sealed in case it comes in to contact with water

Yes, I saw that as well. I think it just a reminder so people pay more attention to close the back cover properly and firmly to avoid water to get in if phone accidently drops in water since s5 designed to prevent from water damage.

Many S5s do not have turning those pop-up warnings off like Verizon models, we need a solution to turning these off without compromising the phone's warranty...
