Lock screen flickering, is this normal?? - Galaxy S II Q&A, Help & Troubleshooting

Greetings XDA'ers, i have a Galaxy S II (international) and it's running stock ICS (XXWLPG) and the "problem" is that right before the lock screen comes up there is some screen flickering, black and white lines flickers vertically across the screen in about half a second before the lockscreen comes up. Its very hard to see this. But its easy to see it in dark rooms, like cinemas and such.
I have already returned the phone to where i bought it, the first time they changed the front LCD panel. and 2. time they didn't fix anything. And here in Norway the third time can get my money back for the phone if the same problem exists for 3 times. And if i do that then i can get the money back. And buy a S III ))
But anyway is this normal, they said they discovered the problem when i send it in the first time. and its still happening. so is this happening to you guys??
-Thanks for your helpfulness

Anyone???

I've not seen it, and you may need to wait longer than 2 hours to get a response from someone who has. This is a forum, not your personal instant messaging support client.

no it's not normal, pretty obvious

Fast vertical lines on screen wake up

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

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.

Weird Flicker when turning on the screen?

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?

[Q] Samsung Galaxy s3 Display/Screen issue

Hey everyone!
Few months ago I bought a Samsung Galaxy S3 (international, GT-i9300) and I noticed a small issue with the display/screen.
A row of semi-transparent icons appear on the screen for as long as it's ON. I don't know if anyone else experienced this issue, to help me out, but it is annoying, wherever I go, whatever I do, those icons remain on the screen, semi-transparent.
Whenever I take a screenshot and send it to my PC, the icons do not appear on the screenshot. I would love to know what this issue is and if there is a possible way to fix it.
I would upload an example how it looks but due to my low post count I am unable to add external picture links.
Use the search facility, this has been asked before.
It's the OLED showing screen burn, like tube TV's used to. There is no cure.

Mine has started with screen burn. In theory its only 12 ish months of every day use. I hope the screens are better on the newer sammys for when my contract ends in december.

Flashing/flickering/artifacting screen?

(UPDATE: Here is a link to a short video of my issue: https://youtu.be/YqKW3tU4Fhw)
So I cant seem to find ANY info relating to this issue aside from results for the LG G4, but the solutions for said phone are all over the place. Some are bad screen, some are related to sim tray, some are related to water damage and battery etc. So basically, about a month after buying this phone (KIW-L24 US version), the screen started to artifact and flash in and out randomly. There is nothing that seems to trigger it. I have set the phone down on a table while on the homescreen and watched the lightshow. It is basically a mixture of the problems seen in these videos (Feat. LG G4).
https://youtu.be/gAUkXLR7eQI And https://youtu.be/QstOH66pfiU.
Symptoms:
Screen will randomly start to flicker and fade in and out. I will also get crazy artifacting lines. (Think de-gaussing an old CRT monitor or simillar to what is seen in the second video)
If i see the problems happening, locking the phone and unlocking again will sometimes fix it temporarily. Other times the problem continues after i turn the screen back on.
Sometimes the screen will refuse to come back on. The backlight turns on, and the digitizer responds, but the screen is still black. Making sure the screen really is off, I can come back to the phone a few minutes later and it will turn on. Other times ill have to hard reset the phone (hold power button 10 sec) and it usually brings the screen back to life.
Background:
I bought the phone "used - Like New" from amazon. It came with all the original accessories and even still had the film protector on the back of the phone. I may have noticed these problems after I received the phone, but they really only started to show about a month after purchase.
At first I though it could be software related as I was running CM13 and something could have been corrupted, so i did not just a factory restore, but a full reflash. This didn't solve the issue. Restarting my phone and the reflash did help, but the problem returned. The inability to turn the screen on persists through a reset and I have to wait till the phone boots again to get the screen back. Sometimes takes more than one reboot. This pretty much confirms a hardware issue right? If i put the phone on a black screen, i can see three small fuzzy "dots" in a triangle shape in the top left quadrant. Could the screen have been damaged by whoever owned it before returning it? They are not dead pixels per se, but seems more like areas where the backlight is showing through ever so slightly more. Not visible unless you are on a black screen in a dark room. Ill upload a video showing some of the issues. Any help is appreciated!
im afraid you need a new display brodar...
Seems to be hardware issue. You can visit the nearest service center to get it fixed for few bucks if you don't have warranty.
Yeah that's what i figured, i just needed conformation. I was able to get amazon to take the return even though I was out of the return period. So at least ill be able to get a refund. Ill just pay the extra for a new one this time haha.
One question : Do u have over heat problem with ur phone ?? If u feel ur phone is more than work from the back dont replace . U'll damage the new screen also . Some ppl erported over heat cpu issue with honor ! ;.

Try moving to stock once , if it fixed stick to it for few days . 99% of possible cases for hardware issue .
So better request for a replacement from huawei . but don't mention them that u bought it used . tell them u bought it new

S6 edge sometimes screen problem help

So I have an S6 edge stock nonrooted 0x0 7.0 and i sometimes have a problem that concernes me
So I leave my phone for a few hours and press home to wake and see my screen divided in 4 parts.
2 top parts are my screen but with colors mixed and fu**ed up hue and all
2 bottom parts are like a broken tv signal snow thingy both divided
I did a screenshot as a proof but after i saw that ss was normal as every else so that was hardware not software problem
Touch work but im not sure where but it works
To fix it I just lock/unlock my phone and its back to normal
Heres a quick sketch I did in PS in attachments
Dino
Last week I've got this problem too. I thought I f**cked up something with my hands when my phone was in my pocket, but after your screenshot I think I was wrong. :laugh:
The only solution was to restart the phone, but it was tricky because the touch sceeen wasn't working properly due to the 4-way sliced screen.
If anyone knows what this is, please tell us. :laugh:
