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
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

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.
Hi everyone!, I'm having this really odd issue with my S2. I've only had it about a week now and this could have been happening all along though I didn't notice it.
Basically If the screen is off and I hit the power button is has this really slight flicker as the screen comes on. It's almost like a single line down the screen right before the wallpaper appears. It's also right-justified on the screen and always in the same spot.
Has anyone else had this issue? It can be reproduced by simply hitting the power button to shut the screen off then hitting it again to turn it on.
Thanks!
Edit: Also the screen doesn't always fade on. 3/5 times it will just "instant-on" where I'll hit the power button and it will instantly show the lock screen tile instead of "fading" into it. Does this happen to anyone else or does it ALWAYS fade in?
I'm probably just being paranoid but I'd rather replace the phone quickly to avoid actually sending it to manufacturer.
Thanks again!
You should take a video of it so we can see if it is normal. I don't see what you describe, and not sure the phone is supposed to "fade in" to the lock screen. Mine is always instant on.
I once flashed to Litening ROM and it had that flicker (lightning style) as a feature I guess, is it the same problem OP stated?
Regards.
Saw it once two days ago, vertically on the extreme left of the screen. Haven't seen it since, but it was very rapid - blink-and-you'll-miss-it job. Can't say it worries me. On Revolution FWIW.

sorry I can't take a video since this is the only device that I own that is capable of taking video.
anyway, yeah - it's really quick. And it's vertically down the screen. I kind of assumed that it was the backlight turning on but I'm pretty certain that happens on the sides right?
Right now it's 10:00 and this issue happens right where the "1" is on the clock at the top of the screen. So starting from that 1 all the way to the bottom.
Again it's REALLY fast - but it's noticeable, I'd have no problem showing it to someone in front of me. It just looks like a single line about the same width as the "1" as well. It almost seems like the one tiny line is showing before the rest of the screen, like if the screen were a "loading process" that line would be the first thing to appear before the rest gets backlit.
Not sure if it matters but it's the model I9100M from Virgin, just incase they are made differently somehow.
This phone has no backlight. The LED's are all individually lit.

Hmm, not the same problem as me - certainly nothing to do with the time here - it was in the afternoon when it happened with me, and my lockscreen clock's in 12 hour format. Clock's also at the bottom of my screen.
Been trying to reproduce it, and can't.

No no, I wasn't saying that the clock had anything to do with it, I was just trying to describe where the line appears on screen. I was also talking about the clock that appears at the very top, not the one on the lock screen. If I just continually tap the power button on and off I can see the "line" appear every time exactly in that spot.
It's pretty noticeable, unless you have the phone away from you - so if you don't see it then it probably isn't happening.
Does anyone think I should return this and get another? I don't really want to run into issues later and have to send to manufacturer. Is this problem big enough that I could get it replaced without issue?
Thank's for the replies!
Sorry, misunderstood. Definitely not my problem, I have no clock in the status bar.
If it happens every time, I'd probably return it if I was you - could be the precursor of something more serious.
Hi again, Thanks for the replies. I realized today that the issue is really only noticeable if you're in a dark room. Even in a semi-lit room it's almost unnoticeable which is probably why I hadnt seen it thus far.
If anyone wouldn't mind flicking the lights off and taking a look I'd appreciate it. If not I'll just return it.
thanks again forum!
I experience it too (at least I think we are talking about the same thing)..it's like it's stuttering and lagging after being in standby. So the first time it renders the lockscreen, the first few frames seem to be rendered at a different pace. If you turn the screen on after a good break, it'll likely do it, but after a few times in a row it instantly shows the screen.
Perhaps it relates to how big the wallpaper for the lockscreen is. I'm not sure, but I've had some huge 2mb pictures set as wallpapers for the lockscreen, and afterwards I think I decided to select a smaller image. I don't know if it was just a placebo effect, but anyways..it still does it with my current picture. I don't really care. You could try a different lockscreen from android market and see if it helps, but I think every SII suffers from this.
I have this exact issue too and it really annoys me! I also bought the phone from Virgin if that is relevant. It's a white streak on the left of the screen for me and only happens every so often. So what's the prognosis? A software fault? Hopefully fixed in a subsequent firmware update? Or a hardware fault worth repairing?
So the latest update did correct most of the banding issues but im still having some glitches when doing some things like half the screen will go away for a second them come right back, it does this very randomly. i also noticed this when playing games like shine runner, it will completely lock up. I included a video of what its doing, its weird in the video it would only do it by using the mouse but when doing it on the home screen if the recent apps filled up all the way to the top of the screen it will do it every time whether I use the mouse or touch. I have only had any of the problems since ICS so i know its probably a bug, anyone else having these issues?

ok i figured it was a bug, its not too big of an issue but i would like to see it fixed soon.
i have this same problem also. it mostly occurs when i'm using youtube. hope they fix it soon because its annoying!
have the same issue it does it for me as well in Google talk, but YouTube is the worse i get a constant flicker for like 2 seconds.
Same for me too, I think I read that Asus stated it was some of the Prime's hardware drivers having incompadability issues with Ice Cream Sandwich (hence no problems with Honeycomb). Anyhow, I believe they stated that they should have an update to fix the issue in February...hopefully early Feb.!

..same here and only seen with Youtube..
Anybody pinged Gary Key or ASUS about it?

Ditto, only rarely and seemingly random but I feel it might be after I've just plugged or unplugged the dock.
Similar issue here though it manifests as very thin bands covering only the left 1 inch of the screen and only when scrolling up and down. This is not a constant problem,but not rare either. Shows up in either orientation. I also occasionally get artifacting usually in the form of a momentary white triangle when I use the task switcher button.
Both of these only started occurring after the most recent update: .11 on 1/17. Before that I had never noticed any screen problems.

I have this bug like you... This bug is on ICS. But my bug is like triangle on screen
Just wanted to be added to the list of users having this problem. The longer i have this tablet, the more issues i run into.
Hope a fix comes in the next few weeks, or Amazon get's it back.
Wanted to bump this thread because it seems like an issue some people are having, but it's not widespread enough that it's gathering the attention that the GPS/WiFi/Bluetooth issues are getting.
Personally I'm getting the diagonal screen flicker on the home screen, especially when pressing the recent apps button. Someone noted in a thread somewhere that this is most common when there are a lot of apps stocked up in there. It also seems to happen a lot more frequently when the dock is plugged in, even without touching the recent apps button - it just happens randomly.
Has anyone tried a factory reset to assuage this? That's probably my next step.
Edit: Come to think of it, I didn't notice any screen flickering until I plugged my tablet into the dock for the first time. Can anyone else with this issue confirm they've been using a dock? I might try something like a factory reset with full battery on both dock and tablet, maybe that'll make a difference...input, please, someone
Still having the same issues after todays update...
Ok, so...apparently, when I touch the recent apps button or when I click down on the mousepad, that's when the flicker occurs. When I just touch the touchpad without clicking, the flicker doesn't happen. What the hell? At least that's got me pretty well convinced that it's a software thing.

Before the update everything was fine. No issue at all. It starts for me after the update. Also made my GPS worse. Wifi is the same (they just change the signal icon to look that my connection is full). So far no reboots or lockups.

I have the screen flicker on
1. Youtube
2. When I am using the dolphin live wallpaper (one that came installed stock)
AS of now youtube is still crashing
Im having the same issue. I just bought my prime yesterday and noticed it while running the SKYRIM live wallpaper. I don't have a dock either so i can confidently say that's not the cause to MY problem (can't say for sure about others) and it happens when pressing recent app list or the settings in the bottom right corner.
Not functional threatening but visually annoying. I love the TFP though I have it next to me at work and im ITCHING to just play with the damn thing. We need more atttention to this.
I just started getting a screen flicker about every 10 seconds with a live wallpaper on. They must have "fixed" the problem with the last update.
Anyone found any solutions for this?
looks like the latest update fixed it, will know for sure after i put it through its paces.
Well, the only problem that I can't live with on my prime is a very weird glitch on the screen. I've noticed this in the Repligo reader app and I am not sure if it happens only in that app. The screen flickers in a noisy fashion. I don't mean that the brightness varies but what I mean is part of the screen momentarily appears like a kind of static signal that you may observe on an old TV (dunno if new TVs do it too).. sometimes the glitch looks a bit different. let me add that this happens rarely... like today :/
Anyone else ever encounter this?

try a soft reset to see if it clears it. put paper clip in hole underneath micro SD card slot. or it could just be a compatibility issue with app itself. do you have force gpu rendering enabled? if so, this is known to cause some graphical issues with certain older apps or whatever. if its enabled, turn it off. it should be off by default. to check, go into Asus settings. then developer options. scroll down and look at force gpu rendering to see.

No, it is off. I checked it immediately once I had the problem. It is a weird bug and happens very rarely. And since it is rare, I dunno if it is problem with that app or it is a coincidence when I am running it. Seems like there is no way to reproduce it consistently to check out the cause. Oh well, at least it is rare.
mine also does this. except not in any particular app, just randomly.
Did it in the camera yesterday, it did it on the home screen 4 days ago when i got it. i am going to take it back next time it does it i think. but am guessing i will need to show them what it is doing.
I had this problem last night, I think its time my BCKOKAS goes home for a cleanup.
Can you guys do a little test?
Steps to reproduce:
1. take the tablet out of the dock (if you have one), turn the screen on.
2. hold it in landscape with your left hand
3. draw an imaginary line between the little arrow guide on the bezel and the clock on the status bar
3. find a point somewhere around half way on that line
4. squeeze the tablet at that particular point using your thumb (on the bezel) and the index finger (on the aluminum back, exactly underneath the thumb)
Please tell me whether you get static on the screen. I have it happening on mine (I have the champagne, CO1 version). One of my friends with a CO2 doesn't have this however, and I'm curious whether this is a widespread issue with CO1, or mine has a bit of a problem. On a side note, it doesn't really bother me, I have it happening very rarely, only when I squeeze it that way or sometimes when I use my right hand on the back next to the right edge to tilt the screen towards me.
I have a problem with my gtab. the screen is kind of flockering. Not the problem with the screen flicker when the tab is low on ram, which was solved with the latest kernel. It is some kind of ... grainy effect. I notized first when I read a Pdf file where the background was black and the letters white. The letters were a little bit moving, as if the pixel were not constant. then I notized it is the same in the taskbar when on landscape, but not on portrait. the numbers of the time were grainy. furthermore the letters of the Apps in the Appdrawer, grainy but only in landscape, not portrait.
How can I solve this problem?

If with grainy you mean that you can see the pixels, that is normal as or device doesn't come with the highest resolution. If it is really moving, that would be odd and is not something I see. Did you check whether it is also present on stock ROM?

I know the screen. I mean not the normal grainy letters coming from low ppi.
The pixels are definitly moving, not all pixel of a letter/number only some of them.
I didnt see something on stock, no.

Hi,
I am facing the same problem. I watched your videos and its the same.
Did u get it checked. Please let me know if you solve this.
Thanks,

Nothing as of yet.
Tablet can be switched on but lies somewhere around
Now I am on a KK Rom - Omni.
Not suprisingly, the flicker is still there...
push?
Any help?
It looks you have a faulty digitizer and/or screen. Since you tried almost every ROM you can safely rule out a software problem (you did test this with a stock ROM as well, right?). So I'm guessing it's hardware related.

Itsa me again...
My tablet seems to be fine again :good:
What did I do?
Two things:
1)
I left the screen on with power plugged in. Nothing else
I do not know if this did the trick.
2)
I overclocked the tab to 1.4 GHz, activated WiFi Bluetooth, max. brightness and ran a stability test with graphics.
I then wrapped the tablet into a blanket (heat generation).
After 15 minutes I heard the battery (it was charged only to 15 % before)
And it was quite hot.
After cooling the tablet down i read a few PDF and no flicker...
Now I have two tablets, one Asus and one Samsung
Any comment on that procedure?
Unfortunately it is back again.
I burned the tablet again, but nothing. Didnt work this time.
Do you have any suggestions how to fix this?
