Hello everybody, I have the following "visual effect". It happens roughly 50% of the times the display switches off. It doesn't matter if it is by it self, by the power button or by a software button. In the very moment when the display switches off, a greenish dot in the center of the display flicks for a split second, along with a same color vertical line trough the whole screen. Obviously it is not supposed to be this way Beside this issue, there is no other problems with the display or the phone( for now). What do you think about this? Thanks in advance
Sounds like a screen off CRT effect, check you tube to see if that is your problem
Isn't the CRT effect a horizontal white line ending up in a dot?
I genuinely think the OP's screen may be defective...

do a lcd test and check if all pixels are working ok
Unfortunately it is not a CRT effect, although it looks a bit like it. The difference is, that the line and the dot( little spot) appear simultaneously for a fraction of a second. In a daylight it is hard to see it, even more it happens just 50% of the times, but not every other time. Its somewhat random.
The *#0*# test do not show much. No dead pixels. On blue you cant see anything, on green and red I think I see a little bit darker spot in the center of the screen( where the dot/spot appears), but there are such darker sports and elsewhere on the screen.
BTW, I noticed recently, that when the screens dims a bit shortly before switching off, this dimming happens not so smooth. How should I say it... it happens on a several steps, although the whole thing is done in less then a second, it is not so fluid. Is it supposed to be this way?
Thanks for your help guys
have u tried flashing a different rom stock
I am on the latest German stock 4.0.4, tried several others, including 2.3.6. .Currently with Hydra kernel. No difference whatsoever. I think the auto-brightness doesnt work so good. When set on fixed value it dims more fluidly.
if u on stock rom and not rooted then take it to a service center

Hi i saw a couple of days ago that my N1 do something odd when turning the screen to sleep mode, sometimes (not always) some thick and soft colored lines (light green or light red) appear and dissappear VERY quickly in the bottom of the screen... is this a normal behavior? Whut should i check to see if my screen is going to fail?
my screen works perfectly but... i really dont like this behavior
I have seen that too a few times; just don't give it too much importance.
Hey Fran!
I see you are latin american just like me!
If you like, you can ask for me messenger so we can chat about cellphones
Dude, im a little paranoic, does this happens very often to you?
have anyone faced this trouble too?
I just noticed this same thing last night. it happens maybe once every 6 times you turn off the screen. it happens on the bottom part of the screen.
however one observation, this does NOT happen if you are viewing the lock screen and then turn off the screen. it only happens when viewing the homescreen, or web browser, etc.
so because of this fact, it doesn't happen all the time, nor on every screen, so that tells me it might be some type of software glitch or power glitch. I don't think this means our screens are failing.
this is a VERY difficult issue to notice.
Thanks for answering Roger!
Im a little bit uncomfortable with this issue because it makes me think that my phone's screen will stop working any time... i may say that i have noticed that this is happening more often now than before...
I hope im just being paranoic about this!!
Please, any input is useful. ):
I just bought a nexus one the other day, and i think I was scammed. THe power button works fine, but occasionally, the screen would get super dim. It doesn't black out because I can faintly see all of the icons and menus, and I can tap them. ALso, its not automatic brightness, because its horribly horribly hard to see. Pulling the battery (sometimes) fixes this problem.
I'm currently running Kang-o-rama with SP2.
Has this ever happened to anyone? If so, how did you fix it?
It does sound its the auto brightness. If you're outside and its dims it is very hard to see. You the default android power widget to test it. It has brightness toggle on it. Full /auto/dim/ and basically the middle.
I'll take a picture of it once my dad comes home, but I tested it last night if it was autobrightness.
I waited for it to dim, then went into settings, disabled autobrightness, and put the brightness all the way up. It was still super dim, and didn't return to normal until I pulled the battery.
I would look for support in the thread for that rom. Or flash another rom. Sounds like it is just a bug in your rom.
I just installed a Miui rom hoping it'll fix it (cause I was using cm7 based roms) and it worked for a while.
Now it began to Flicker and finally turned off. It'll ring when phones call it but nothing will show on the screen. I'll pull the battery but this time nothing shows up (though it vibrates indicating it turns on).
I know this is a hardware problem now, do you guys know what part it is?
Please, any input is appreciated.

Hi All,
Actually I bought a new Note-GTN7000 but later after four day's I've noticed that there is a tiny green dot appearing on the not exactly but middle of the OLED. It is not a dead pixel as it appears on a dark background only like when we go to the settings menu(Dark Background) & it disappears when I switch of my handset.
Could be a pixel stuck.
Q!: Is there a way to take it off.
Q2: Tried different apps like JscreenFix and pixel fixer for about an hour or two continuously but didn't work out.
Any other possible way from any body???
Please help.
I once had a stuck pixel on tytn 2 and this is what I did:
Hold your finger or "closed" pen on a pixel(so you'll know where it is)
Turn off your screen
Press the spot on the screen very hard
Turn on the screen
This procedure helped me to "unstuck" the pixel. I cant guarantee that it will work om amoled but I think it is worth to try

Pushing the spot hard and Switching the display on, Heating up the screen works for LCD Screens. Not LED.
Don't try these silly steps posted everywhere, You might end up permanently damaging your screen.
The only solution to this is, Stop looking at it. I have a stuck pixel on lower left corner as well. They don't spread nor hurt anything. In fact its so tiny that You wont notice it until you continuously focus your eyes on it. In a couple of days you will forget that It's their.
For LCD Monitors back in the days - Samsung only replaced Monitors with new ones if "only" they had Five or more dead pixels. If you have one , or two you're stuck with that for good. #yearsago
Looks as if I'm going to have to join the return game on this device. I've been a very happy TF700 owner on CROMi-X for the last year and still had that WOW effect when I started playing with this tablet.
Until it got dark.... I mean - the attached picture is with the tablet in sleep mode!!!!! That's gotta suck the battery dry like nothing.....
Opened a ticket with Asus for what it's worth...
I'm going to update to 4.3 manually, but don't expect that'll do much.
Does anybody have something similar?
Edit: After about an hour of reading the screen dimmed and had dark shadows on both sides. I flashed the 4.3 update manually since the System Update wouldn't - now everything seems to be fine.
Light bleed gone when in sleep mode and no shadows either... ?????????
Weird, glad you got it sorted out.

Unfortunately it's not resolved to the point that I feel confident to unlock.
I still have have weird and uneven dimming of the screen. Sometimes just part of the screen dims and shows a dark, uneven shadow across it (in reading mode). What I don't understand is, taking a screen shot in that situation shows nothing of the shadow....??
What I consistently see is when the screen times out, it dims just before it turns off, but only on part of the screen (more or less the left half, but fading out from left to right).
Smart Saving is off.. Can't think of anything else to try...
I'd hate to return it, but I think I'll have to - this does not inspire confidence....

Smart saving has nothing to do with smart dimming unfortunately. You can only turn smart dimming off if you are rooted. I'd take it back and get a replacement as what you are seeing is not normal.

Never seen this on any tablet.
To me it seems that some parts of the Led backlight are not working correct or totally not.
Better try to get it swapped or Rma'd ASAP.

I was filling out the Amazon return form and picked it up 'cause I got a notification about new mail - and that's when the digitizer gave up completely.
I was able to wipe my data by hooking it up to the TV and got it to reset with a lot of huntin' and pecking.
A replacement is on it's way. You gotta love Amazon :cyclops:
My note 8 is 1 and half years old now. about 2 month ago, it start to have an issue that the screen will become yellow and blurred if turn off the screen and turn on again within 5 seconds. when the screen become yellow, the brightness of the screen will drop, also the text on the screen feels like got a shadow effect. Not related to night mode/blue light filter/google book night mode etc, all tested on/off and no use. and recent month it become even worse, when the phone become hot it will also become dim and yellow. any solutions?
the dim and yellow effect even visible when the phone restart and show the SAMSUNG boot animation. when dial *#0*#, check the color, red looks like orange, green is ok, blue looks like purple...

You need a new screen unfortunately. That's not going to go away it's going to get worse.

I agree! Sounds like the display has developed an issue.
well, it seems so, have to replace the display. but the display actually can show the colors well -- when it's cool, and when you press button to activate the screen after the screen had been off for at least 5 seconds.
if there can be a software solution, disable the dim color mask when the phone is hot, then I can save the money for replace the screen...
