[v2][Dec 27] AMOLED Burn-in Fixer - Nexus 6 Themes and Apps

AMOLED Burn-in Fix
Hey Guys,
I wrote a quick app to fix the burnin for AMOLED screens.
"Burn-in" is caused by an uneven wear on the screen and can only be reversed when the uneven portions are worn like the rest of the screen.
By using this app you are guaranteed to wear only the status bar and/or navigation bar so the effects of burn-in should be reduced.
Its pretty simple for now, I may add a timer in the future if anyone is interested.

Thanks,
Change Log

Can't we just enable inverted mode in the settings without this app and get the same results??

You can, but this app was specifically designed to only have the status bar and navigation bar lit while active.

Erm, you can just use an app that full screen flashes to solve the issue.

This is the one I have used the most i run it for about an hour every week

That app is for LCD burn-in, not amoled.
Read my description for how this app works

Good job man. Don't let those who come off as ungrateful keep you from creating things like this.
No need to have your entire screen inverted or flashing when you can simply target the two problem areas..

N6,stock,rooted,nonencrypted,leankernel;installed the app,but invert all colors,not just nav and status bar;what i do wrong?I dont see in Accesibility your app.

When you invert the color you should be brought back to the app. From there simply click hide settings and your nav/status bar should be inverted

1) I appreciate BlackDino's work. I had this unevenly aged burn-in on my statusbar & navbar.
2) I now know why Samsung ALWAYS puts a gray tint on their statusbar, so phone's screen is more evenly used/lit
3) what's with attacking the developer? I'm a little bit disappointed by XDA's lack of action to mediate the attack on developers. This app poses zero threat. Developers like BlackDino should be celebrated for her/is well intention for the community.
4) Thanks for the app, BlackDino!
And I think some people get too worked up, just call this issue uneven tan-lines issue .

Thanks for this app

Thanks for the application.
In the future, a scheduler would be perfect.

Great app. Have a reminder to use this. Any auto run for X minutes would be a cool add as well

Any recommendations on how long to run the app per day to prevent "burn in"?

Per day maybe 1-2 minutes.
I'd check the tester every time you finish to see what the damage is like.
If the damage is pretty bad I'd do one longer than the other ones to try and balance out the wear

Display currently has no burn in as I have been babying it. For prevention would you recommend the same amount of time? Thanks!

With amoled there really isn't any sort of perversion, since its all about which parts of the screen have been worn.
Check the tester to see if there any signs of burn-in, if not then you should be good for now

Help Xperia Z1s Status Bar Turns Grey in Settings/Dialer

No idea what has caused this... but when I enter settings it goes from Black (nova launcher) or transparent (stock xperia) to a dull gray.
Thanks in advance.

Not a dark grey, but a lighter dull flat grey on top and bottom.
Does it change color when you enter settings from the stock launcher?

This is really stressing me out. Whether I messed something up or it was like that all along... it looks horrible.
Is there a way to change android settings menus (as well as the notification bar/bottom button bar) to black and get rid of this horrible white/grey theme that doesn't involve an unlocked bootloader? I'm hoping to find an easy fix for this once root is available.
Same thing on my phone, if you use nova launcher to change the bar color it works except in sonys custom settings, which probably means the color of the bars there is handled different hence why nova launcher can't change it. Would probably need something like a custom rom/root or maybe 4.4 to do this.
This is stock and normal. You're like the third person I've seen complaining about this today? I don't understand why it's a problem.
Uh yeah.. It's supposed to do that.

Honestly it's not a problem aside from the fact that it's unsightly. I was afraid messed something up.
So even without nova it would still turn grey?

Yep, this is controlled by the Dialer and Settings APKs - you won't be able to change it without modifying those APKs or a custom ROM/app which supports forcing status bar colors. I'm not too involved in that stuff, though, so that's about as much of a jumping off point as I can give you.
To be honest, I didn't even notice it until people started getting excited about. Different folks...

Maybe i was so excited about everything else that i didn't notice that. I wonder if it was intentional to signify importance or caution or if it was simply overlooked.

I think it's simply a case of the status bar/button panel (whatever it's called) blending the default black color with the white-ish background of the app. I assume it's just the application of translucency and alpha blending. Change the bgcolor of those apps, probably goes away. Maybe there are some other white-background apps to prove that theory.

Good catch. I replaced stock Messaging with 8sms to fix group threading. 8sms doesn't have the gray bars, even with the light theme, but stock Messaging definitely does.

Nexus 6 Amoled Display Artifacts [THREAD CLOSED]

I've had my Nexus for only 2 days and I've noticed some artifacts on my display. I've included screenshots using Screen Test app which show some horizontal lines on my display and also vertical lines but these are more vivid on the device itself they don't seem to show so much in the screenshots. These lines are visible regardless of what I use as wallpaper. Anyone else having this issue or is this normal?? Will this clear up over time or do I need to send it in for an RMA??

LMFAO....
Ok, so because you are obviously clueless about the distinction between hardware and software, any visual artifact caused by the AMOLED display **CAN NOT** appear on a screenshot.
Those lines you are seeing are due to the DITHERING algorithm used to generate the gradient that you are displaying. Gradient = the progression from white to black through multiple degrees of gray. This is a function of SOFTWARE, not hardware. RMA will do ABSOLUTELY NOTHING for this.
I understand there are different gradients, this is different, what I'm seeing is lines gradient or not but they are obvious even when not using the screen test app, they are visible everywhere at anytime doesn't matter what background or wallpaper I'm using. There are vertical lines also that look like they are baked into the screen.
Well then send it for an RMA? i dont see what your purpose of this post was, to ask if its normal to have baked in horizontal lines? its not.
i dont see any lines on my display, so i would sent it back for a replacement. i guess i was one of the lucky few with a device with no issues, the only issue i found was that i did not get any lollipop with the device, see here : http://forum.xda-developers.com/nexus-6/help/missing-lollipop-nexus-6-t3046877

Hey man thanks for your reply, my question is really aiming at anyone else with the same issue. I didn't think it was right, I guess I was just hoping that it would resolve itself somehow but obviously not. As for lollipop, yeah my device came with it, why what did you get on yours, KitKat???

I definitely cant see anything on the screenshot. As for the camera photos, its tricky because they are a little pixelated, probably due to the contrast.

I think it might be a good idea to go to an optometrist to make sure that the lines aren't caused by your eyes.
Your going to have these vertical lines had them on all amoled screens. But if your seeing them on say like your home screen and other places I'd get a replacement. But if you only see them say with just a white or gray screen I wouldn't worry about it. If you want you can try this app out on Google play... Amoled burn in fixer.. Good day
Thanks for your comments guys, I believe I do have an issue with my display therefore will proceed with a DOA replacement. Cheers

Interesting screen color mod from chainfire CF.lumen v3.16

Thought this display App may interest some.
[APP][4.4+][2015.10.28] CF.lumen v3.16

Doesn't work for me. I even tried 3.00 because 3.16 didn't work on my G4 either.

Works fine, although I prefer the ease-of-use of Dimly (same non-root operating principle, i.e. colour screen overlay).
However lately I have been using Pixel Filter, which draws a fine, invisible grid of black pixels (configurable density), that changes at regular intervals to evenly protect the AMOLED against burn-in. I use this app when reading in the dark too.

Thanks for this. I have been using f.lux on my iPhone and have looking for something similar to try once my 6P eventually arrives. So far I've had my eye on: twilight, lux auto brightness and bluelight filter. I'll check this one out as well. Really wish my phone would hurry up and ship!
Will cf.lumen burn in the screen?

They're about the same just look a bit different, this is designed more for root while twilight is focused on non-root.

It would be much easier to spot any problem with your display with a uniform dark background. The current black background with non uniform white patches is a bad choice.
Here is my own. It cant be a burn in as its visible in the screenshot and disaperes if i watch a video, look in my gallery ect. Only visible on homescreen.

I think your mistaken in thinking his wallpaper has the gradient actually in the image, it does not. It happens with any black wallpaper !
This has been happening as long as I can remember on my Sammy devices... It does not effect live wallpapers therefore you set your wallpaper with a live wallpaper app that lets you choose your own image.

Wait.
Are they talking about the gradient looking thing at the top of the screen? That's normal for the statusbar to do that. There's an app called L Speed (for rooted devices) that lets you disable it since it's a RAM flag that creates that effect.
If it was screen burn-in, we wouldn't be able to see it in a screenshot, lol (which they do, but because it's software related, baked into the phone's settings).

[Q] Want front camera led to be used for notifications please!

1. Can or will this led be used for notifications in the future?
2. Does it have different colours?
Would be great if someone has some answers!

Sound slike it's coming in the future but you can do this through Always On Edge. There's an option for the pixels around the led for a colored ring.
It works. However, the dev was a real Dbag when I called him out for hiding the true app purchase price inside of one of the "Watch ad" buttons needed to save the options to test this thing out.
Anyway, it's not a bad alternative. I don't like that it makes you do an extra step (i.e. thumb print twice), but it is cool enough for now.
Will give this a go, thanks pal

Thanks for this! I don't like the built in lock screen and like over a hundred options you have to choose from and add etc.... However it's so promising though as we now definitely know samsung has access to modify and set this as an option as said in the samsung forum I posted! Can't wait if samsung pushes this in the next update! :fingers-crossed:

NoLED https://forum.xda-developers.com/showthread.php?t=730692 might work, but it didn't work well on my pixel on pie, worked fine on Oreo on my Tab S4.
They use the screen as a notification and have dots or icons that move around to keep screen burn in at bay. Doesn't work so well on LCD screens but nice on OLEDs with minimal battery use.
