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

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

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.
Last week i flashed my Vibrant to 4.0.3 and i found some times i can't use half left vibrant's screen, but when i turn off screen and turn on i used ok.

Just to be clear, do you mean that your phone doesn't register your fingers touching the screen on the left side of the phone sometimes?
I would suggest downloading the free app "Touch Test" which shows a grid that not only shows where you are touching, but the path of your slides across the screen. If the phone begins to act up again, you can open the act and see if and where the screen is cutting out in the grid. Aside from that, it might simply be that you need a replacement and its coincidental that it was acting up along side you running a 4.0 rom.

That is the oddest thing I have ever heard lol
It really might be a hardware issue man...I can't think of how it could be the rom. I mean, sure you might occasionally
have an unresponsive touchscreen....but only half the screen working?? That's just weird Oo I'll keep looking around for answers though man
but thus far I've found very little.
Good luck

I have a video but i'm new member i can't send link to my post. I will sent to your inbox. tk
Okay, so that anyone else that happens to come to this thread is on board, here is the video that shows his problem:
http://www.youtube.com/watch?v=5xDolJhmDog&feature=youtu.be
As you can see in the app, if the origin of the trail is on the right side of his screen, the swipe is recognized across over to the left without problem...if however the origin is on the left side of the screen, no touch is recognized until he reached the middle of the screen, at which point it becomes recognized.
I am still looking around for a similar problem, but thus far have few ideas. Typically, the screen either is totally unresponsive or momentarily unresponsive...never half and half, and especially with such weird rules. By this, I mean that obviously the left side of the device is capable of recognizing touches, since if he begins at the right side, it does just fine....the only problem is if he originally touches the left side, then it doesn't recognize it.
My guess: it could be a kernel issue.
I would try the following:
Pull battery and reboot. Take out any external SD card.
Back up what important apps or data you have and try a factory reset.
You can also try some the options below:
1. Reflashing the kernel.
2. Try a different kernel if available.
3. Factory reset and full wipe and flash a different ics or cm9 rom to see it the problem persist. You can try to isolate the issue to hardware or firmware.
4. Full reset and flash back to complete stock to see if the problem persists. If you are fully reseted and back on stock eclair or froyo and the problem persists, you may have to open up the device to check all the connections.
sometimes a bad battery may also creates some problems
Now i'm using xerxes custom 2.3.6 gingerbread. It's ok but i don't know why when i use ics. I can use half left screen

A couple of days ago, i discovered that I have one pixel that is stuck or frozen. It's a very noticeable red spot, which is easy to see on light backgrounds.
I have tried to download pixel-fixer-apps from Play, but none worked after i ran them for 30 minutes.
Is the only solution to get a replacement phone?
Yep, this new i'd be sending it back for an exchange

Before you try anything stupid, there is an LCD-testing program built in to any and every Samsung-branded device, open it by typing
Code:
*#0*#
in the dialer-pad.
Then test your screen, if you still experience those problems, try booting the device into recovery, it may just be a problem with Android, if the problem is still noticable in Odin/Download and/or recovery mode, then get a replacement, if not, try flashing a new ROM.. It doesn't have to be custom...
I personally have never experienced such failures of device screens, I've seen touch-screens not sensing touches, I've seen screens go black, out of nowhere, but I've never, really, never heard of a dead pixel on a HD super Amoled, or Amoled at all, in fact...
I wish good luck in finding out what it is!

Thanks for the replies!
I've done some research, and tried different types of troubleshooting. The dot is still visible while testing with the samsung-code, and it's there in recovery/download mode. I've reset and installed different types of roms, customs, stock, and different kernels, without any change. I think I'm just going to send it back. Triangle Away and flashing a stock rom worked flawlessly
OLED screens don't suffer from pixel death. There might be some "lazy" pixels but the pixels don't just die on OLED screens.

Okay, thanks! Maybe I should try that first.
Any idea how long it took?
I'm also having this problem the past few days, blue pixel in the centre of the screen.
Tried the solutions mentioned here and on other forums but no luck yet
Hi, so here is the thing: Every now and then, usually daily, I take the phone out of pocket, unlock it, and it starts doing random presses on the screen, usually on the middle section, top to bottom. It ends up in the weather app, app drawer etc.
I try wiping it profusely to make sure there isn't any sweat or anything on it to cause it, but no luck. I tried rebooting, and sometimes it fixes the issue but most of the times it doesn't. I have a friend that has one and it started doing the same for him. Mine is Vodafone, his is Orange, so the firmware isn't EXACTLY the same... Anybody had this issue? Any ideeas?

Well, my Desire X (Vodafone) started to do the same thing in winter, I think it was due to low temperatures, so I believe that those random presses are sign of temperature/screen issue. Also my phone did this (sometimes) when it's overheated, maybe it can be temperature-sensitive screen.

Lol, dirty screen

Oooo matron! When my phone thinks about you it touches itself.
Mine does it too, I think it's down to any moisture (sweat etc) on the screen, seems to go absolutely bananas in that situation. The LCD used in this device is pretty poor and prone to these things. Finding a keyboard for the DX was annoying. Have 4 installed at the moment. Far easier in my expereience on the old Desire AMOLED screen etc.
Hey guys,
I got my Redmi note 2 yesterday and I'm having trouble with the touchscreen. sometimes it seems to be perfectly fine and sometimes it doesn't react properly. It seems to be worse in the right half of the screen. Sometimes I start scrolling and it works fine in the beginning, then the screen stops detecting my finger and when it detects it again, it opens the thing that my finger is on instead of scrolling.
I'm not sure if this is a hardware of a software bug.
Would calibrating the screen help? If so, whats the best way to do that?
I would usually try flashing a clean stock rom (the one it came with has some bloatware anyway) and test if that resolves the issue, but that's probably not the best idea if I decide to return it.
thanks for your help

Try entering in the MTK Eng. Mode, then go to Hardware Testing->TouchScreen->HandWriting and try drawing some lines crossing the point where the problem occurs.
A friend of mine had a Nexus 5 with a malfunctioning touchscreen, doing a similar test we noticed that there was a full horizontal line where the touch were not detected so every vertical line we were trying to draw were broken on the point where the bad line were crossed.
Obviously in that case it was an hw fault.
EDIT:
Reading your post again, it seems a behavior caused by lag, so maybe it's a sw problem and not an hw one, especially for the fact that "it opens things instead of scrolling".
Does it always happen in the same point/area? Or is it totally random?

I already did that and the results are very inconsitent. When I first tried it, it started drawing a line as it should, then it stopped and started again half a centimeter later, then it stopped again, and it pretty much went like that from top to bottom of the screen (at least on the right side of the screen, the left side worked better).
When I did the same test again, it didn't even draw lines, it just highlighted a few single pixels along the way that my finger was traveling.
And currently everything works perfect and smooth as it should.
It does kind of feel like a software-thing, but in my mind (correct me if I'm wrong) that should affect the complete screen equally and it just doesn't. I tried pulling down the notification bar earlier, from the top right of the screen and it just didn't work. I did a few tries and nothing happened. Then I tried pulling it down from the top left and it worked fine.
As I said it works fine at the moment, but I guess I'll make a few screenshots and a video of the problem, when it occurs again.
Ok, so the problem came back and I was able to do some more testing and make a video (sorry about the shabby quality, but it'll have to do ).
youtube . com / watch?v=rKsponNr9lA
As it turns out, the whole screen is affected equally, so I'm pretty confident that it's just the software but I'd still like to hear a second opinion.
The thing that kinda throws me off is that the reboot didn't help at all...
So what do you think? Is it just buggy software?
I'd try contacting the seller and explaining him the problem.
Maybe he will ask you to flash a new rom to be sure that it's a hardware problem and not something that could be solved without a replacement. That's what happened with my first phone from China.
If not, you could ask him and I think he will authorize you.
