I don't know how many of you guys that have had the same issue as me so i will ask flat out.
Is your LCD showing signs of "burn in" syndrome?
For example, if i have opera open for 10min then jump to a gray or black screen, i can still see the opera menu like a "ghost" and it can be like that for like 2min before it gradually dissapears.
Is this a sign of an old LCD? Or is it a sign of something else? Is the graphics starting to freak out?

I get that on my "first batch" Tab (bought in December 2010) after the charging error "battery temperature too hot or cold" message has been on screen. It goes right away if I switch to a picture or other color dense image that resets the pixels. I don't think it's burn-in per se, since it can be reset, but it's something akin to it.
The battery message I get is another story, however.
Just an idea, have you tried if it's different with a kernel without LCD undervolting?

Yeah, I just flashed the Overcome 4.0 kernel a few days ago and it's still the same thing. Probably battery or sensor issue. Alas. It still charges eventually.

How old is your tab?
Is there a way to establish the manufacture date based on serial no. or similar?
I haven't seen this problem on my Tab, bought last May/June (from Germany); but then that info is of no use since I don't know the manufacturer date
I know that supercurio was asking for LCD name before. Don't remember how I checked that thou haha. Check his thread.
Its weird that I can feel that it happens differently on different temperatures...

Earlier today I got into a discussion about CRT monitors with a bunch of nerds. We all spoke lovingly of the ffffffTWWAANGGGGGGG noise that degaussing makes and the general benefits of doing this action periodically to your screens. One of the gentlemen in the room mentioned that his Motorola Droid Evo 4g has a screen flicker and washout much like a crt that needs a degaussing.
This led me to wonder, "Why hasn't the dev community created a degaussing application for our phones?" After all, we spend dozens to hundreds of hours and dollars in modification to and accessorizing our phones. Why not take it a step further and make sure that the screen itself has an even longer life?
So who is with me dev scene? I'm to damn stupid to develop this application as my fundamental knowledge of how linux actually works on a ground level is severely lacking. I implore one of you randy fancypants out there: Please help nerds have that delicious fffffTWANNGGGG again.
Edit: I just realized this would be much better suited for general android application development. Can a mod move it?
hey matey, this would be a great idea, however lcd's dont need deguassing lol
althought it would be amazing as a screen on animation or a timeout animation lol
i can see why you want a degaussing feature but i dont really think its necessary and that's wiithout taking into account its impossible lol.
degaussing is he method of clearing magnetic interferance and other electrostatic interferences out of the screen that just dont effect a lcd screen which is one of the benifits of them
great idea though!!
Okay well that being said I think it would be a fantastic boot animation/noise.
of course ! that would be amazing, using it as animation and boot animation would be cool... have you seen the CRT animation for screen off and on, its on cyanogen mod roms its pretty neat!

SGS4g actually needs degaussing- mine at least
I tricked a nephew of mine to trade an old samsung S4g vibrant (tmobile) with a relatively new Galaxy Y. I wanted to play around with an older phone for tweaking experiments and I noticed after a month now (and 5 Roms and several wipes) that a shadow of the android keyboard shows up everytime the screen displays a white background. It does not show up on black though and it reminds me of the old degauss issue with crt monitors.... Is there any solution for this?

This sounds exactly like LCD burn-in. I don't think there's much you can do about it if the screen already shows ghost images like that.
A fake degauss would be a great animation for a FC, but since something is already crashing, wouldn't the animation have trouble playing smoothly, especially full-screen?
(Apologies for the junk post, but I'm trying to get enough posts to give feedback on stuff in the Dev section.)
Not sure if anyone has had this happen before (I searched, but maybe didn't use the right terms).
Every so often (sometimes less than once a month, sometimes every week), the phone wakes to this sort of display where all the colours are inverted, and washed out. Requires me to reboot or wear sunglasses. See pic below, I also inverted the colours on the version on the right, showing the phone is really inverting and messing the colours up.
I have observed it with both ROMs: Gauner Desire HD, and imilka Incredible Sense 1.1 (currently running).
Any clues as to what is causing this?

Hi guys,
I just sold my "old" SGS2 which I bought on the second or third week of launch of the international version and got a new one. Here are some of the things that I've noticed:
1. Red spot on white background picture while using the camera is GONE. I thought this was a software problem before but I guess it must have been hardware related. Flashed two different roms now including the stock one and still no red spot.
2. Yellow stain on the lower portion of the notification bar is gone. Color is even with no hint of the yellow stain that plagued earlier versions of the unit.
3. Color of the screen is noticeably darker. You wont be able to notice this most of the time but on apps like dialer one wherein the default background color is gray, you can really see a huge difference. Darker but not less brighter, I don't know how to describe it but you can really tell the difference.
4. Capacitive button lights are much dimmer. I tried them on different kernels and roms and they're still dimmer. Not a dealbreaker though.
Overall I am very pleased that Samsung quietly addressed these manufacturing issues
*edit* actually I'm not sure if I was just lucky or they really fixed it
Concerning the screen, you just got lucky. The yellow tint is still here on new batches. One thing I noticed however, is that the two new units I used, had no processor usage interference when headphones were used. Did they add proper shielding or was I lucky as well?
Actually I think I spoke a little too soon. Apparently the white's and the grays are my screen are a lil darker than usual and a little to the shade of purple. Some people have it as well. My white's are not as white as before but when i turn the brightness up it turns into a pretty good shade of white. But my grays are definitely more purple.
Oh well
Every sgs2 is unique, i like to think (so i don't get annoyed by it) that every sgs2 is a piece of hand-made craftsmanship.
Noticed the darker colours on my friends new SGS2 also. .

Pretty sure sammy havent fixed anything, as some one said ur lucky as am i lol. My phone has no screen issues. Just the usual getting hot problem, so i dropped cpu to 1000mhz and undervolted, much better. If the new GS3 has a quad core processor it will be a sweet portable heater. ;-)

Hello,
I picked up my GS4 about a week ago but haven't really used it in direct sunlight until today. I was outside, and the sun was shining brightly on the screen. Home screen was fine, and darker images were ok, but if I were to go to an app with a primarily white background, or open up something which used the keyboard (texting) the screen would flicker pretty noticeably. Brightness is all the way up, and auto tone was off.
Has anyone else seen this?
yup this is normal esp when using the keyboard.
Im not sure if it will be fixed.

Its a hardware thing, but also its only in touchwiz so a developer might be able to turn it off so to speak.
It adjusts the color and tone no matter what to save the display from overheating and or burning in...
Does it a lot and I notice it cause im weird about those kinds of things.
If you use CM 10.1 or AOKP its gone.
ive made some progress with the RGB light meter on this; hoping a friend can write up some code so we can test out a 'smoothed out' transition and sampling rate and one that is sped up, averaged faster, but will take up more CPU and RAM and battery but more accurate.
here is another thread regarding it:
http://forum.xda-developers.com/showthread.php?t=2280715
http://forum.xda-developers.com/showthread.php?t=2284726
Maybe if someone who is using CM10 or AOKP could test it to see if it is a software issues and not a hardware issue?
edit: slade and jet replied while I was writing this...thanks for the info. looks like it is touchwiz related.
edit2: just went out in the sun again to test a lot of different options in the display settings (which none worked) but is seems it is only happening when the keyboard is enabled. I am using swiftkey.
yeah TW and that sensor communicate; i believe the sensor itself probably works better ALONE, but TW changes it and throttles it for either battery or screen safety.
It is always dependent on what is being pulled up on the screen, though it can be mitigated quite a bit if you disable all power saving and screen auto features, and leave brightness under 80% or so.
yea anything under 80% in direct sun is basically black. all power saving and screen auto modes were disabled. i covered up all of the sensors too and it still flickered....

Not just a sensor thing per-say.
It's hard to explain, they most likely did it because they didn't want the amoled to burn in.
Its the same reason why the brightness goes up another 34% or so on auto above the max brightness. Only uses it when needed to save the screen and battery.
Does it on youtube too btw, bring up a video on wide screen then tap it and you'll see the drastic color shift
I noticed this thing when I got my phone also. I thought I was just imagining it but I guess it's an actual problem

Hi everybody. Recently I bought a J7 pro for several reasons, one of which was Always on Display, a.k.a AOD. However from the first night I used it as a night clock I could apparently see that the background of the clock and notifications is not black and has a faint light. The funny part is that the preview of AOD is fine with all the black pixels off, but when you actually use it, all the pixels are on. I asked several J730F owners and they had the same problem, however my device is J730G. Please test and report. Just remember the environment must be completely dark.

Hey
I have the same problem
I have a j730f/D's
It's really frustrating and I guess it drains the battery a lot
I also noticed the that the preview of the aod is perfect on all brightness levels
Maybe thats because the display panel uses different settings when real aod is on ( like udervoltage and lower refresh rate things like this but I am not an expert )
Also visible on 3rd party apps from the PlayStore
I guess Samsung is using some hardware tweaks there to optimise battery life
What I also noticed is when the real aod is set to full brightness because of the sunlight the screen really gets black ( you can try this with a flashlight or so )
But on the lowest brightness the screen gets grey .
Would love to know if this is just software related or hardware
Because if it is hardware I give it a try and send it back

That's exactly my situation as well. On low brightness the screen is unbearably gray, otherwise it seems to be completely black. I guess you can try sending it back, unfortunately I don't have that option.
3rd party apps sucks because they can't use this special display mode Samsung uses
Maybe I will send it back
But I am not sure about that I wanted to wait until an update is coming, maybe it's software related so they can fix it .
I also send an email to Samsung but I saw your post on the Samsung forum so I don't expect too much
With how many ppl did you talk about that problem that have the j730f ? I mean it doesn't make sense to send it back and get a new one if it is a problem for every device
I got the same issue on my J730G/DS. When on low brightness aod, i can notice the whole screen lighting up a little bit. But on high brightness it is completely black. I think all j7 pro have this issue. At least we could try to send it back to samsung and see if they will fix or even do something about this issue.

I found several threads out there talking about this problem. Generally the problem was with S7 and other Samsung flagship devices. In all the circumstances there, the problem only was fixed by changing the AMOLED panel. However here in J7 pro it seems that when the screen is well lit, the black is truly black and when the ambient sensor reduces the light the problem shows its ugly face. This problem was not mentioned anywhere in those threads I mentioned.

Although I hope so and believe that j7 problem is different from previous problems seen on other faulty aods, but the way aod works is different from the way other aod apps work.
Hey guys
I've borrowed my friend's J7 Pro to see if she had this AOD problem. After I bring it to a very dark place, the AOD works like it should (No grayish AOD background). Guess it's a hardware problem. I will try to send it back to Samsung if I have time.

The AOD uses the ambient light sensor to decide what brightness should be used ( I think AOD only recognize Dark and Bright situation, just like most of the proximity sensors )
So because it's dark, the screen also adjust itself to dark situation. No grayish background is seen. I compare mine with her side by side and I can see the difference.
Another thing to proof that this is a hardware problem is that when you put your finger on the fingerprint sensor and it unlocks, between the unlocking process, you can see the screen flicker before it unlocks the phone. Same as when you boot up the phone. Right after when you press the power button and it vibrate, you can see a flicker before "Samsung Galaxy J7 Pro" is shown.

I will find some time to send it back to Samsung. The distance from My home to the nearest Samsung Service Center is very far, took me about half an hour with usual traffic. But they are usually traffic jammed, so I predict an hour trip to the SSC. Not an easy job though I'm very busy all day.

If you all notice, the official samsung's AOD app for our J7 pro is not available anymore in Play Store. Why they remove support for our device? Why? From the feedback there, a lot of j7 pro owner report about this aod problem...
