Any One Notice this? Bright Line flash on the screen - Galaxy Tab 7.7 General

This happened about once per hour, my screen will flash ,i means : a bright line appears at the left edge of my screen, brighter than anything i have ever seen normally on this screen, and disappear immediately. and not thing more is wrong.
I am using the CM9 Rom from locerra and it is a great rom, i don't know if this is caused by the rom, but i have not notice this when running stock HC.
I am just worrying if this will do any harm to the screen, or is there any way to get rid of it?
I have not find any pattern when will this show up, it has been shown when i am watching a movie on the MX player, and when i am using Chrome.
Has Anyone noticed this?

Just noticed this for the first time with LQ2

test
As test, turn off Surface dithering under settings -> performance
Edit: seems this is jackpot, have not seen the white left line issue anymore..
EDIT2 : nope, still on left side seldom, also noticed on bottom once today

Try the app SyPressure.
In my p6810 with stock ICS the app triggers the white line to flash like mad.
Try and report if you be so kind.

Experienced this a few times. Stock ICS, left side too.

Screen changes tint when you swipe

Somewhat hard to describe, but fairly basic.
When I swipe over to another home page, the screen will tint darker for a second, and then tint lighter again immediately.
Has anyone else noticed this?
FWIW I'm rooted and running Eugene's vanilla 2.1 Vibrant9.
Yea I know what you're talking about... never paid too much attention to it though. All of my Android phones have done that (G1, MyTouch, Cliq, and now Vibrant) in wondering if it is an illussion.
Sent from my SGH-T959 using XDA App
Its definitely not an illusion.
I owned a Incredible, EVO and now this and I've never even noticed it until tonight.
I didn't even notice the first few days I had the phone.
So is this a general thing across Android that I never noticed, because its seriously bothering me now.
Using ADW launcher now? Coz I've noticed the widget goes a little blurry for a split second when I swipe the screen. I think it has something to do with the tweaks of the launcher.
It may be the "power save mode" readjusting the brightness levels for the change in screen content.
Sent from Samsung Vibrant
Yeah I turned off the power save feature and it still does it.
Sent from my SGH-T959 using XDA App
When I go to contacts, I noticed if I leave the page idle for just 2 seconds it has a green tine to it but once I swipe down it goes back to normal.
I never noticed it until I started using ADW on my Vibrant.

Are you guys talking about swiping the notification bar? This DOES adjust the brightness so long you have auto brightness turned off!
Nah not the notification bar, simply going either left or right on the home screen to another home screen.

Unless there's an issue with your touchscreen calibration, that shouldn't be happening.
Swiping across the notification bar adjusts the screen's brightness. I think you're accidentally swiping it by mistake and not realizing it.
I noticed this in the web browser when I first purchased the phone. It's very noticeable on a site like XDA with a light background. The screen's tint changes while holding down the screen and dragging it around. No idea why.
It's not a bug. It's built into TouchWIZ. Heres an example. Go into your contacts and just look at the tint. Now scroll down, the tint changes. The tint changes as you scroll because the little letters on the right side are activated.
I never noticed it doing that in the browser but I probably could liken it to the scroll bar on your CPU browser. Perhaps as you scroll, it changes because of that.
Like I said. In contacts, it's a feature. If you have it done in the browser- I don't. Maybe your phone has a bug.
It does it on every screen on the phone, not just contacts, not just browser.
Hopefully my g2 wont be doing this.

No problem here. Running stock from the factory.

Something is wrong with my screen please help

I just noticed today that there is a bright line at the bottom of my screen. Tried changing wallpaper rebooting made no difference. Not sure if its a burned line on the screen now. I have attached a screen shot, any suggestion or test method I can check would be greatly appreciated.

Lol can't see it which means its probably something wrong with your display

If it's the display itself that's having a problem, you need to take a pic of it using a camera. A screen shot is just a capture of what's being projected on the screen, not the screen itself.
I had the same problem after a screen replacement on my phone which I originally broke the screen on. I would suggested taking it back to the store for a replacement handset.

Don't think so, I feel your pain mate. Its a line of dead pixels on mine it was really bright then after a few days then typically after about 2 days it changed to a really really faint line which was barely visible.

that's exactly what I have right now. A really bright thin line. this is a canadian bell sg 2 and I have rooted and unlocked with chainfire cf-root using zs kg2 kernel. So I got a yellow triangle that I need to get rid off. Any suggestions? I'm worry about the counter where they may be able to tell that the phone is has been tempered. :-(

Restore to stock firmware and reset the custom rom download counter using a USB jig.

Image Retention(?) On N4

I saw someone ask this in a nexus circle on G+ and though maybe it was just his device but a few people posted also claiming the same so tried it myself and noticed it also.
If you put your phone on max brightness and go to an app that leaves the logo on the screen like G+ in the upper left hand corner, imagine FB or whatever else will work the same, and stay there for about 2 minutes then switch to a dark screen(clock) the image is still visible in the corner. It stays there for a few minutes too, then its gone. Is this normal of IPS displays or even LCD for that matter? I mean its very circumstantial, you would have to at max bright and on that type of app for a long time and then to a dark screen to ever notice it but if you went longer under them conditions could it potentially burn in permanently?

This happens on my tablet (TFT LCD), but not on my Nexus 4. It shouldn't cause burn in, LCDs don't burn in

Hi there ! The one asking the question on G+ was me !
I'll post a video on youtube and open a poll about it here !
P.S. it seems that many people do suffer from the problem (cf. http://forum.xda-developers.com/showthread.php?t=2228013&page=4) Therefore I won't be making the video (I think)...
It happens to me all the time. Especially noticeable at night when using it in bed so it doesn't even have to be at maximum brightness.

Nice, I tried to search on my phone for the topic but for some reason search from the xda app never really gets me the same results as when I'm on my browser.

[Q] Display brightness issue

I'm currently on my second N3 (the first one had vertical lines in photos) and looks like this one has a bad display. When using Tapatalk with the dark theme, the bottom left corner/edge of the display is brighter than the rest. When testing with Screen Adjuster, the difference is very noticeable. The issue can be seen even with just Thumb Keyboard with WP7 theme.
Has anyone else noticed this kind of problem?
Return it and buy from another store. Seems like these guys are selling you lemons.

The two phones are from different stores, I'm still waiting for a replacement for the first one.
Mine upper side screen seems brighter than below screen.. but this condition only happen when i use xda app set to dark theme..i thought the xda app the one that problem..not the phone...

Check it with the stock messaging app, it should have a uniform brightness. Mine is glowing on the left edge and especially on the bottom left corner.

The problem can not be seen in a screenshot. And the camera lines disappeared after a hard reset but came back soon after.

You may notice that the black screen when you open the settings. Not symmetric Colors.
There is a difference in the backlight. Increase in the left of the screen.
AMOLED has no backlight! the issue is due to the production process (basically: the more of the center of the wafer your particular screen has been cut out, the more uniform it will be)!

Change from Adapt Display to Dynamic. Best thing to do to resolve the problem.

If you want to get rid of display brightness issues, just switch to Dynamic, as the 'blacks' in Settings would be even blacker, to the point where it doesn't really light up as it uses the OLED technique of showing true black.

Display of black weird

Anybody an idea whether this is a display damage? Black appears not normal.

Black crush
Well,this is called 'black crush' or 'black clipping'. It is still there a little bit,but nothing serious. The first Note was horrible... Don't worry,nothing is wrong with the phone,it is a software issue,and (I think) it will be fixed soon.
Im very confused as it really distorts the display of the black.
In the settings the search field has a deep Black. Rest is more or less grey.
In the toggle menu the bottom bar has weird stripes.
It's not just a small issue. ...

You posted screen shots. No one can tell anything from those you need to take a picture of the problem using a camera. The phone's been out for over a month now. If what's happening to you were wide spread I assure you it would have been brought up (numerous times) by now. If whatever you're seeing was like that out of the box (before you loaded any apps) it's probably a h/w problem with your specific device.
I have the same issue too on my Note 3!
I'm from Singapore here.
I didn't notice that the pictures appear perfectly normal on other displays.
I did some shots with a camera.

That isn't normal - I'd you are running a custom ROM I'd take back to stock to see if the issue persists, and send it back if it does.

Mine too. Isn't that supposed to be the way the display looks? Just kidding.
A display that looks like this isn't normal and if there were a lot of them people would be going nuts.
It's either something s/w related that's fried the graphics drivers or a h/w problem unique to specific phones. If it remains after a hard reset than it's h/w and the phone needs to be exchanged.
Tried the hardware reset but didn't change anything. Bad luck this time.....

That is really something wrong.
It suppose no strip at telco area.
Beside search bar, the rest bottom part is suppose black also not grey.
I believe your screen is defective.
I've factory-rested and it's the same.
Re-installing exactly the same J1 firmware (in Singapore it's the latest) via Odin also yeilds same result.
Another friend of mine is facing the same issue.
However, the ambience at the Samsung stores are so bright, and it's hard for the customer service officers to see
Well I'll see what Samsung After service Germany will say... the point is that the screen looks ok if you test the blue, green, red and black screen test under *#0*#. But during normal use I'm faced with the problems as shown above
I'll keep you updated.
