people, has anyone of you noticed white vertical lines that appear for a fraction of a second when you power on the device? it happens right before lock screen appears... best could be seen in a dark... seems like there is a problem with screen initialization on a driver level...
Could someone check this issue?
Using Lightning ROM 1.5
Sounds like your phone is defective.

i prefer to be more optimistic due to the fact that many others reported the same problem on different forum... xda is more reliable, so I'm trying to collect the opinions here as well
Mine has this, noticed it for the first time yesterday (hadn't seen any reports of this at that time).

don't worry, I think this effect is present on every piece of 9100. more or less obvious for users... it might be not vertical lines that people see but the quick white flash

What effect does this have on any other aspect of the phone, or is it literally only that fraction of a second that there is any apparent effect?

if it is really a problem of display controller low-level driver - it might cause some serious problems as time passes... total screen failure, for instance... as i remember from past cell phones - it was the first sign of upcoming screen death...
but i think that in our case - this is just a minor driver issue in screen initialization process... at least i believe so
I have this problem with the screen as well! and it's annoying to see those vertical lines whenever I wake up the screen.
sometime i can see the lines with "CRT Screen Off" mod, but without they dont appear
Try to do a backup in CW recovery and flash a stock rom.
It can be the CRT effect or any other custom rom issue.
It would be great to know if the problem is due to your custom rom or not.
Hey, sorry to bring this up again, but I'm having the same problem, and it's really bothering me. If there's any way of fixing it, please let me know, I just uploaded the stock ICS 4.0.3 for my device, and it started to show.
mine too has this
Mine also has this issue. only visible in the dark
yeah, same here. I thought i was the only one having this
Sent from my GT-I9100 using xda premium
Noticed this straight away when I got my new phone and it was there before I flashed a custom anything
***Bezeke HOLO LPQ base running bits stuff from everywhere ***
I also have this issue
One large, white vertical line. Clearly visible in all lighting conditions
However sometimes (rarely) it doesn't do it.
I have compared this to a black galaxy s2 (mines white) which doesn't suffer from this issue. It actually seems to delay the screen on / unlock time
The black loads the lockscreen at almost the exact same time as the white displays the lines.
I've been putting off returning it under warranty as I can't do without it..
Its like a jolt of power that hits the screen
***Bezeke HOLO LPQ base running bits stuff from everywhere ***
yeah, i recently got a phone off someone, and it's been bothering me since, there's no way of fixing it? i hope it hasn't caused anyone trouble, i recently switched to iPhone to this phone and i'm absolutely loving it besides the white flash
hi
i have three galaxy i9100
two of them are black
and the last one is white
and relax every i9100 has this

If you mean the minute, almost "patterned" grey lines then yes. Every Galaxy S2 has theses.
But bright white, clearly visible line/s which delay the screen-on process.. No, not every Galaxy S2 has it.
Especially if they don't always appear
i don't think its an issue with the phone i had it running an old version of omega rom the latest 5.1 does'nt have that problem.
I just picked up my S3 and the whole screen had a hazy green tint on the lock screen and was the same when I unlocked, and I wasn't gonna mess about so rebooted quick and back to normal now, and I read another thread about it but isn't clear why it happens, but I checked the battery graph and there's just a huge gap as if no power was getting through at all, so has anyone else had this happen on S3 and what's causing it?

Just had this, I put my phone into my shoulder bag, cycled for 10 minutes, picked up the phone and the entire screen was green as if the red and blue pins from a monitor cable had disconnected.
I'm also having charging difficulties, although that may be the cables.
I'm on CM9, literally just updated to the newest nightly now to see if that sorts any issues. There's something just not quite right about this phone of mine. A quick reset was all it took to sort the screen out but it was scary to think such an issue could occur.
All I know is it's something to do with a sudden dip in power and I read about other phones doing it too very occasionally, and after it happened there was a gap on the battery chart as if the phone was getting no power at all.
Sounds like the OS or at least an important process crashed or got stuck (deadlock, livelock, ...).
Green color has something to do with the rendering process and/or screen calibration. All Galaxy S1 with Voodoo patches for the display color values show a green screen for a very short instant after screen-on.
That also explains the gap in the battery stats since a non-functional OS cannot collect any informations.
Did you run any particular apps which might be causing it?
Without any details I can only recommend the standard package: flash your OS again, factory-reset it.
Maybe wiping the cache is enough. Maybe it's a hardware fault, hard to say...
I just rebooted and I've already upgraded since then, and I wasn't doing anything really at the time except I think that was around the time I used G L to SD and it broke the Play Store, but when it Hulked on me I hadn't touched phone for 40 minutes and that's what I saw when I woke it up. but most people say it's a once in a lifetime thing so not really worried.
Hello.
When I leave my phone in sleep mode (screen locked and light off) and try to wake with On/Off button, sometimes I get a black screen with a faintly image. The touchscreen works and all the buttons, and if you click 2 times On/Off button - the image appears all ok. I tried to flash another stock ROM - all the same. Then I`ve unlocked the bootloader, rooted the phone and even did the S-off with wire trick (1.53 Hboot). Then I`ve tried 3-4 custom ROMs with 6-7 different kernels, from stock to custom, but all the same. Yes, I`ve updated the firmware file, also, but with no difference.
Well, I see that this problem is not so usual, but I couldn`t find any real solution. Did anyone have this kind of problem and solved it? Since I got this phone from another country - official warranty is out of the question, I need a DIY solution.
Any help is greatly appreciated.
THX in advance!!!
I would have to say it looks like the light for your screen is dying, I had my screen replaced once, my screen would flicker from very dark to very bright

hmmmm, but when I get the OK image - it doesn`t flicker or go from dark to bright, it only has trouble to "wake up from sleep mode". even when i relock the screen quickly and don`t leave it unused for 2-3 minutes, the screen works OK every time....it looks like a software problem, but still I didn`t manage to fix it with all the ROMs/kernels/firmwares I`ve flashed....

Thinking about how to troubleshoot if hardware or software. When in sleep mode, instead of using the power button, I would have the phone plugged into a computer and use the " adb reboot " command to reboot the phone without touching the phone a few times and see if it lights up correctly. The first thing you should see is the boot screen, and if it works every time, then you do have an issue with your firmware. If you don't see that boot screen first every time, then as much as it sucks, I would guess there is a hardware issue.
Good luck, but this is the easiest way I know of to help determine what the issue likely is.
Minor update here, the first thing (at least on mine) that I see is the lock screen for just a quick second or two, then it quickly goes into the boot sequence. This is important as in "sleep" the ROM is running, so if the first thing you see is the boot sequence every time, and not the lock screen, then it points more to a software problem than a hardware issue. CM9 had an issue for the epic4g where you had to turn it off and on sometimes to get the keyboard to light. They found the issue in the firmware causing it.
Just wanted to make this as accurate as possible.
Wow so I am not the only person with this problem. The EVO 3D that I have was replacement phone that was given to me from Sprint from the first EVO 3D that I had which had issues with the digitizer. I received the replacement phone this past Tuesday and it worked fine for two days. It was not rooted and I did install the ICS update. On Friday morning I took it off the charger and went to work, while in the break room the screen suddenly went black and I could not get the phone to display anything after that. The Android function buttons at the bottom will light up but the screen wont, the phone also gets hot even with it powered off.
Long story short, I took it back to the Sprint store where they ordered me yet another replacement EVO 3D. Has anyone had to go through 3 EVO 3Ds or more?

Excellent thinking, I didn't think in that direction. I'll try this tomorow, since I'm not at home. My personal oppinion that it's a software problem but if I did all the above - what did I miss? If I flashed the firmware, ROM and kernel, what else is left untouched that could affect the LCD? Could anyone suggest a good kernel? Or can I downgrade the firmware, since no one had such a problem with GB?
just to inform all - I tried all soft solutions, but all the samo. finaly - I replaced the LCD and everything is OK.
THX all for help
Display backlight is not working of a sudden even when i keep the brightness at max and second screen is working but the display is not working with good backlight ! I just took the phone from my pocket and what i seen is the display is dim ! Display is so dim even when the brightness is kept at full and i dont know how this happenned and someone tell me the way to solve this problem ! Screen is very dim even when i adjusted the brightness level at max and i even tried formatting phone but the issue remained same
Hi this also just happened to me. Image is working but no brightness in screen except some bright ess in top right corner. Phone overheated a couple kf times and shutdown after this initially happened and consumed 2 full batter chages in minutes. Now the heat and battery problem is gone but screen still dark. Any ideas
Hi guys!
I`m having the very same problem. Back light of the main screen is gone, and it doesn`t matter how I adjust it, it is always dark.
Have you guys solved your problem already? Any ideas?

Having the same issue as of yesterday, been Googling possible reasons and it seems the 'backlight controller' has malfunctioned and the entire screen needs replacing (allegedly). Considering a new screen costs almost as much as the V10 itself on ebay these days I'm going to be trying to take mine apart to see if an easier fix is possible, it is more than likely there isn't, but I at least have to try. Let me know if any of you guys have any luck in repairing your phones

Update: Having replaced the screen with a new replacement screen, I am still having the same issue, indicating an issue with either the mainboard and/or the chipset. Can't really go much further with this it would seem so unfortunately I don't think the issue has any DIY fix...
Sorry guys... RIP my V10

I have Same problem,, Any solution ? please help me
My LG70 just did this for a few minutes
My LG70 just did this for a few minutes. Scared me to think my phone was dying. Restarted, still the same. While I was googling it, the screen came back on. Hope it stays that way. Really strange to take it out of my pocket and only have the screen lit in the upper right hand corner. I hope this wasn't a preview of things to come. Love this phone and want it to last!
Dear all,
today my lemax2 alarm did not ring.
20 min later i had a phone call but i did not hear the opponent.
after a resarted everything work fine for 1h.
after i pluged in the charger the screen went black.
since then i tryed several things like unplug-plug, press start button long also tried startbutton+ volume down..........
what i belive so far is that the mobile does everithing right without showing it on the display.
the display gets dark gray (from black) when i swich ist on. the start android vibration comes normaly and when i let it start long enough i hear the fingerprint working and when i dobblepress the start button the camaera swiches on.
do you think this is hardware or software?
and what shoud i do next?
it is a lemax2 6gb 820 with twrp and oreo
and thx for any help i get
hello again,
i am sure now that the phone starts android normaly because my smartwatch schows me the new whatsapp massages.
interestingly whatsapp said that my clock does not fit any more to my country!
The screen hase 3 diffenent shades of gray.
black when switcht off
dark grey when i swicht the mobile on
and somtimes a much brighter gray during starting android.
BUT: the screen is gray since the hole day
even if i go to recovery.
can it still be a software problem? because if it is a hardware defect i would send it back for warranty.
update
i flashed now twrp again from my PC via ADB.
screen is still black (lighted gray)
i belive now that it is a hardware problem.
is it possible to instal the original bootloader and rom without the phonescreen?
or do you think its nessersary befor i send it back for warrenty?
thanks in advance

It really sounds like a hard ware problem. Probably the shades are just from the backlight on the display. I guess the display itself is broken or something. Can you get to the recovery mode? If you don't see it just use your warranty.

no, also recovery stays gray.
and yes, the gray looks like backlight.
do you think that i should try to flash it back to normal bootloader befor and send it back?
can they say that the screen brocke because of the flashed rom?
