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?

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

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

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 had my razr for about 2 weeks, and this problem already happen to me a few times.
The touch screen will suddenly not responding to ANY touch, only the the buttons are still working(include the 4 buttons on the bottom).
I had to hard reboot my phone to get it working again.
Does anyone face the same issue?

Yes I also face this type of problem while playing games. Screen become unresponsive while playing but can solve by pressing power button(no need to reboot).Not on 2.3.5 base only on 2.3.6.
I also face this problem, after updating my rom to arctic 2.0 rom, which uses some stuff from 2.3.6.....power does not help, have to hard reboot. any idea why?
I've had this problem happen to me on my Droid RAZR (CDMA Verizon), can't remember if its before or after I was rooted... I just had to hard restart and its only happened once since then.

The power button does not work for me
I had try to press the power button, but then the screen still not responding, so I cannot pass through the lock screen, and have to hard reboot......
I am on stock rom, 2.3.5, the Asian version.
But it seems it does not matter to different region's razr since the cdma one had the same issue

I get this too. I had 3 razrs, first two had dead pixels so I had them replaced, all had this issue. Has not happened in awhile and I can't remember if it was always with a game, but at least one time it was with a game. Anyway, I don't think this has to do with rooting because my first one I never rooted and it did this. Don't remember if power button worked or not, but I had to reboot as well with power and volume down, or up, whatever it is, to get it to respond again.
No problems here.
I have had this happen about 4 or 5 times for me as well - got it day of launch. Mine says it is the XT912 though - is that right?
XT912 is the Verizon specific one, so yes.
Seems to be a fairly common issue. What is the chance that this is a software problem as opposed to a hardware one and so will be fixed with an update?
I had it happen for the first time yesterday after about 5 weeks or so, strange cause I wasn't doing anything. Battery was at about 15% though...
I only encounter this bug when I open Rom Toolbox for the first time and the superuser permissions screen shows up. My screen doesnt respond to touch anymore. I have to use the power button to make it work. Thats it. It happens nowhere else.
I've been using ROM Toolbox since day one, can't say it's the issue.

Happened to me today...any need to panic?? On official Stock ROM 2.3.5...
Also, is this a hardware issue or software??
My problem is bit different, on a 4 month old unrooted razr.
Touch screen will start to fail recognizing my sywpe typing and start jumping all over the place, or it will end the word while I'm still sywping the word...
Sometimes it types in different letters (1/2 keyboard away) when I'm not sywping to avoid this BS when it happens.
Unfortunately, I cannot reproduce this result whenever I want to, I'm currently trying to reproduce the situation.
I believe this happens more often when my battery is low... or when I have been using it for an extensive time.
I go to draw program to test if it is the hardware problem and it is jumpy too, but not by much.
The problem does get better with reboot, but not 100% of the time, so I can't conclude it is SW problem
I also have issues with this. I think the problem is software side. It seems to be poorly responsive often after I unlock my phone and try to swipe screens.
Also while typing quickly with two hands it often does not input all the letters I type, although it flashes the keys and acknowledges that I touched them (this one might be a keyboard issues, not sure yet)
And ya, on an all black screen, I'm noticing some dead pixels- a lot of rectangular patches of dead pixels. I don't really notice it anytime else except when it's all black.
Been making me double think my choice, but I will wait for ICS update and possibly bootloader bypass. But.. I might be getting another phone shortly just because of the size (bezel mostly), these touch screen issues, and the performance isn't exactly where I anticipated it to be.
Razr XT910 touchscreen randomly jumping or not responding
I'm having all the problems mentioned earlier:
- touchscreen stops working randomly
- touch "jumps", like someone is touching it in random places
- some letters on the keybord stop working randomly
- phone gets quite hot at the top
My XT910 is not altered in any way, stock android 2.3.5, as updated as possible.
This happened when it was up-to-date and the very clean one.
This happens really irregularily. At first it happened when I played multitouch games - at some point the touchscreen just stopped responding and could only go back or lock the screen (but not unlock it, obviously).
Twice it happened when I was just going through messages or contacts.
I sent it to Motorola to fix it - they just reset it, benchmarked it for 45seconds and sent it back.
The very evening I got it back I tried to "heat" it myself - I installed a lot of apps, played a lot multitouch games on 3d graphic and voila! - it started freaking out like never before (vidoe in zip file attached).
My last idea is that it happens because of a low quality generic anti-scratch foil on the screen. So I threw it away and tried to "heat" the phone again - nothing.
I used a different foil - anti-reflecting + benchmarking apps - nothing.
If it happens again I'll send it with this video + the one I'll make then.
Hope it gets Motorola specialists off their ass and back to work .
Hey there, my maxx has this weird issue with it's screen too.
Take for example, a game with on screen controller like reckless racing. If i push the screen too long, it won't recognize my press anymore in the pressed area. I tried to go back home, thinking this is the game issue, but it's not, the home launcher button that coincidentally in the same location with game control button is unclickable. i tried with phone tester app and it show the same symptom, the pressed area indicator will disappear within 1-2 minutes.
The only solution is to turn off display and turn it on again. Should i bring it to service center?

Hello, I've recently having this exact same problems with my Motorola Droid Razr Maxx.
The screen sometimes doesn't respond as it should:
-Random touches.
-Not detecting swipes.
-Not detecting anything at all after long press.
-Detecting the touch location wrongly...
When this happens, sometimes a reboot fixes everything. Others, I just have to stop using the phone, and come back later.
Has anyone managed to find a possible cause and/or solution to this problem?
I've tried diferent roms, full reset, rsd flashes... But still the same problem
I am absolutely satisfied with this phone . BUT i have one problem . When i push the power buton it takes between 0.2 and 2 secound to appear the lock screen. What should i do to make it faster? Becouse the waiting is disappointing with this hardware ....
if u want instant on u will need all of you 4 cores to stay awaken at full speed at all time u still want it ?
it goes to power saving mode thats why it needs 2 secs to be awaken

It's right , but my old desire hd had about 0.5 sec to wake up . This is why i asked it .
It's a battery saving feature. You can turn off S-Voice on lockscreen from the S-Voice settings, or just completely disable the whole application like I did, and this speeds up the wake process a little bit.

Yes i have already done that . But this lag is really annoying . Mainly because its not always the same ammount . Sometimes it takes 3 secounds but sometimes its a half secound. I really dont know what to do...
If your USB cable is connected, it wakes up instantly, if not, there is a lag. This is a feature (!) of Samsung phones. We discussed it deeply on this thread in SGS2 forum:
http://forum.xda-developers.com/showthread.php?t=1136223
Basically, it's epic failure by Samsung and there's no solution.
It can't be explained by saying phone needs to sleep, because HTC, LG, Sony, Motorola phones sleep too and none of them needs so long to wake up.
oh well in terms of when your actually using the phone, nothing compares to the speed and fluidity of Sammy phones. Isnt really an issue that it takes a second longer to wake up

Yes, but they also dont tend to have as good standby battery life on HTC, LG, Sony or Moto phones.
I'm not defending them completely but this is a design decision rather than a bug. That said, on the Galaxy Note it has been almost completely alleviated since the ICS upgrade.

I noticed it only recently after screwing around @ 1.8ghz that suddenly the phone is taking sometimes millisec or sometimes even 3 secs to go to lock screen and also ripple is slowed if immediately try to unlock. I thought maybe i messed up some part of hardware by o/cing it too much. Even my old LG O3D takes just a sec. ANyway glad to know it's a common thing and not my phone being fkd up.
I can't judge, I take several minutes to wake up.
Still waiting...

Thank you for all the answers!
Ive noticed this too, its frustrating, makes the phone feel laggy.
My S2 was running CM9 and that was sharp as hell, no messing about, is this something that will in time be fixed with a custom rom?
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.

May be kernel or rom problem. 2nd did you overclock/undervoltage it? That may be the problem.
Or it is your amoled screen
Try ICS and GB, completely wipe your phone, if that doesn't work its a hardware problem = go to service.
Sounds like a the voltages on your GPU or CPU are set wrong or an incompatibility with your kernel clashing with your phone. Revert back to before what ever you flashed if you flashed something.
If not, it's hardware like @Dakura said, could be one of the two or even both.
Battery or the screen.
Battery is cheap to replace.
Try the battery and then the screen if it continues.
Hey @ GreekBlood.. I have not overclocked or undervoltage it.. I tried flashing it to stock rom but it doesn't helped.. is there another way to get rid of the lines on the screen? ?

Sorry @sharanchopra ! You can download no Frills CPU.
You can try and change the governor to Performace and see if the issue goes away, if not & your phone isn't under warranty anymore i'd suggest taking it apart and making sure everything is nice and snug on the inside. (Flex cable wise your lcd&digitalizer mighten be plugged in properly).

Hi,
I think this is a hardware problem (Screen problem). If you have warranty, they will change your display. If not, you can do this.
Regards.
