[Q] for those that use the xda app

When you start the app, at the xda splach screen is the bronze / red colour the same across the whole screen or is it like a gradient getting lighter towards the top left?
Just wondering if my screen is duff but maybe I'll be better downloading a screen test app.

No, nothing wrong with your screen for that reason. Just loaded xda and it does change shades from top to bottom.
If you think there's issue with the screen, google search for a photographic color calibration image, that should give you a good image to check with.

Thanks. I thought that was the case as I haven't seen this problem in any other apps or when using the phone normally. Still a relief to hear though!

no clue, i have set mine to DARK theme to safe power.
but when i look at a BLANK WHITE page, the 2 bottom corners just above the 4 soft buttons have a weird purplish gradient, which did not exist in Galaxy S
but that is due the Concave screen design

Mines on dark also but I'm talking about the splash screen that shows on starting the app - whether light or dark theme selected.
No such purple tint here.

The xda splash screen gradient looks a little banded because of the pentile sub pixel layout of the amoled screen. Nothing really wrong with your screen, that's just the way it is with these screens. It's a trade off.

Don't think I'm seeing banding, it's just the fact the xda splash screen tends to lighten as it gets to the top left of the screen.
From what others have said this seems normal though so. I'm not concerned.

Ah got it, I mis read. Yeah I think that's normal.

This is slightly off topic but relevant to the xda app. When I first view a new thread using the app, it always jumps either to the last page or a random page. Or if the thread is only one page long, it starts halfway down the thread. Again this is for new threads I've never viewed before. Anyone else experiencing this or know how I can fix this?
Thanks!

Yep seeing this too and never quite worked out the pattern / reason.
Don't worry about hijacking the thread, my question was answered long ago

i have a very nice and smooth dark brown to light brown gradient going from bottom right to top left
on the Galaxy S
the same gradient looks like chopped, chunky, banded, it's like looking at a picture in 16bit color (SGS) vs 32bit color (SNS)

That's originally what I meant with my post cause I see the banding on my screen too. It should be identical since these screens are literally identical I believe.

that's what i would like to know as well.. i was left when i did the comparison

[Q] Are there any OLED friendly themes?

OLED screens blow away LCDs in almost every way, except for one, longevity. The blue emmiter subpixels wear faster then the others. Static images especially ones using blue subpixels can damage your screen.
I notice that most themes use loads of blue everywhere. That is also the color which burns in the quickest on OLED screens. Also static images like the battery, wifi etc at the top are always there. This also can result in screen burn. Unless you want your screen to start to look like an old Pac-Man arcade screen care should be taken.
Since this is the Infuse section and everyone has an OLED screen has anyone made a theme using colors with as little blue as possible (white uses blue sub pixels so that don't count). Colors with mostly red green mixtures are the most OLED safe. I wouldn't mind if those static indicators on the top at least were all in yellow, red etc and at a lower brightness than the rest of the screen.

Idk about you but my screen IBM's super Amoled + not oled ....

OLED, Super AMOLED, AMOLED plus, super duper AMOLED 12,000 +, all the same tech.
The characteristics of the emmiters in Organic Light Emmiting Diodes are exactly the same, blue wears faster. The only differences are how it is driven (AM= Active Matrix) and the plus is just the pattern of the subpixels (RGB or pentile). If it has OLED anywhere in it, your screen WILL get images burned in if you have static images on the screen for too long and blue will wear sooner, much sooner, than the rest of the colors.
So BE CAREFULL! if you have your brightness cranked avoid static images, unless you like them so much that you want them permanently part of the screen!
Is there a way I can hack a ROM to just change the graphics? I am no coder but I can tweak the art.

And i can build android....until u have its ppl like u the reason all us devs are leaving this forum...nobody reads...nobody listens...

Why not use miui? You can easily set up a theme to suit your needs. My screen has no specific blues in it (just red/black/Grey).

Sent from my SAMSUNG-SGH-I997 using xda premium

actually i do have a solution if you dont mind things looking funny. other than looking for themes that have less blue and white and purple you could download chainfire 3d and use one of the night mode settings. the red or amber or green settings should help. chainfire 3d is some kind of intermediary driver that can allowq the gpu to process apis for other gpu's (assuming you have the appropriate files that are surprisingly hard to find but i have copies if anyone needs them for a specific game or anything) but one of the features is for either night viewing or for power saving and (assuming you have oled of some kind) and it will selectively remove or reduce the levels of the different colors. this could also be good for using your phone as a hud (heads up display) or just making navigation a little less distracting at night.
edit; now ther eis a plugin for the pay version that will automagically change color settigns based on light conditions and time of day so you can have full color when it's important and reduce blue in the evening so it's not so blinding and to save your screen from excessive blue burn in. it can also set the colors according to color temperature or custom rgb mixing.

Hmm...changing the colors of your theme sounds like preventing burn in.
I've never experienced burn in, so I'm not help.

As often as new phones come out on the market, I'll probably upgrade my phone before it has a chance to overdose on blue.
Besides, isn't that what your auto screen shutoff feature is for?
When you are actively using you're phone which means the screen is constantly changing, I don't see much chance of images getting burned onto the screen. If you like to leave your screen on and look at the pretty pictures, that might be different, ie. you will risk burning images onto your screen!

Except that some things don't really change much while using like the battery, clock, wifi etc at the top of the screen. Mine came flashed with a custom ROM (bought used) and with the theme that is on there the guy who made it went mental with blue. Everything is blue, even the wifi and battery charge indicator.

Help: Pls post settings screen picture

Hey guys , i think my htc one x screens white is not as white as it should be. my brother has a internation htc one x and his whites are way more superior. maybe color temp on at&t is bit warmer? is there any way to fix it? it getts a lot better at highest brightness.
if you guys can post your settings screen( since it will show good amount of white) snapshot at full brightness and lowest brightness with your room light off ,using some camera , it will be greatly appreciated. this will help me compare my screen.
would have posted mine but i dont have good camera in hand. Will try to get hold of one soon
thanks

I'm the one off. Two one x's and never had yellowing
Sent from my HTC One X

When I was looking at the one X before I bought mine, the at&t store had 2 on display. One white model and one Grey. The screens on them were TOTALLY different!! The white phone had yellow whites and the Grey phone had perfect beautiful whites. Needless to say I bought a Grey phone because at the store that phone just looked better to me. Lol. Luckily the phone I got has the perfect whites.

People posting pics isn't going to work. They would need to take a picture with the same brand & model camera as you (and same settings), or the white balance will be different. You best bet is to go to the store and compare versus display models, or ask them to unbox one.

Can burn-in be removed with apps (e.g. Display Tester)?

Hey everyone, I bought my HTC One S used, and at a discounted price because of screen burn-in. The burn-in isn't noticeable at higher brightness settings, but when there is a dark background applied, or when the backlight is dim, you can clearly see burned in areas.
Has anyone had any success using any burn-in removal techniques with apps like Display Tester?

What exactly is screen burn-in? Is it the same as the screen has different color depending on what angle you are looking at it? My experience is when i look directly on my screen, it show some yellowish in white background, but when i tilt it forward or backward, the white becomes white with no yellowish color. And when i turn it sideways it become pinkish.. do you think my screen is busted? Or is it what you call the screen burn-in?

TC is probably referring to ghosting. Kinda like

Notice the faint icons? As to fixing it, I don't believe there is a way other than replacing the screen. It happens when an image is displayed without movement. It sort of "burns" into the screen, and when viewing something else, its slightly visible, thus "ghosting"
As for the yellow tint you see in the whole screen, I believe some displays are just like that.

tbh i wonder what would happen if you attempted to burn in the color inverted (dont do it, lol)
But most likely a new screen, which isn't too expensive.
If you had a big enough discount, it'd be no problem.

[fix]fix for smearing issue [updated 19/7/2013]

Update: 6/5/2013
* replaced method 1 with new method
Update: 19/7/2013
* added new hardware level fix for 9500 users
As of now we all know that almost all s4 units is suffering from smearing issue. After fiddling with some apps here and there I found a temporary solution , this should be handy until Samsung fixes it.
I suggest two method for this issue, Method 1 adjusts the rgb values of the screen(overlays) .Method 2 adjusts the contrast levels of the screen.
With both the above mentioned methods the black levels are not pitch black but will be on par with the blacks of s3 or anyother amoled screens. I prefer method 1, if you guys face any problems with method 1 then you can try method 2.
Method 1:
1.install screen adjuster app from market.
2.Set the values of green, blue, red between 5 to10(I prefer 5) and turn on the filter
3.job done
Method 2:
1.install screen adjuster app from market.
2.change the contrast level from -0 to -10(you can go upto -20 depending on how far your eyes can balance between smearing and pitch black)
3.turn on the adjuster.
4.job done
Method 3: (HARDWARE LEVEL FIX ONLY FOR 9500 USERS)
This method fixes the smearing at hardware level and changes contrast level of black backgrounds without touching other colors and dosent drains battery like screen adjuster. Thankst to @AndreiLux and @Slimmer77 for their contribution on screen calibration for 9500

One is software and causes battery drain and applies to all colours if you want it or not, and the other is hardware, costs nothing and targets only black.

Will give a 1.56% grey on blacks and removes all smearing. You need to set digital brightness reduction to 0 though since I didn't plan for this use-case and it negates the above "fix".

1.Install a custom kernel that supports screen calibration.
2.goto screen tab

3.Flash the attached zip file

Users who hate the non black background(especially it looks poor when used along with smearing fix) introduced by samsung on newer roms can flash teh blac background mod attached in this post
Note: Running screen adjuster on background will disable the "install" button while installing apps manually, so disable screen adjuster before you start installing something and resume using screen filter after the installation is over

Personally, if you can fix or at least hide the issue with the above then at the very worst Samsung may change some settings in later roms to the same effect. I am hoping that it is actually a driver issue and a proper fix will come along....
This is an assumption but as the above works then I cannot see it being a hardware issue but then I am no expert.....

Won't this affect battery life? It seems to negate the power saving effect of AMOLED. I believe the smearing comes from the pixels going from off (black) to on (grey) and that switch time not happening fast enough. This app and workaround does definitely work, but it seems that it works because it's changing everything from black to veryyy very dark grey (still looks pretty black to me) however that means that the pixels aren't off if they're displaying grey instead of black right?

ok thx balagamer but its only patch for now hope samsung will fix it as i dont wanna blacks like on SGS3 and i really hope sammys fix wont be the same and they will steal the true black from us...that why i bought amoled right for the blacks

That's how the black looks on s3. Now I can understand why the blacks are pitch black in s4 compared to other galaxies to some extent.

I believe this is indeed the case. Samsung could fix that by maintaining the pixels lit at the lowest power level, like with the previous Galaxy phones. I'm not sure if it's worth it though. Hopefully there'll be some even better work-around.

thats how samsung displayed the blacks in their past galaxy devices. With s4 the black pixels are completely turned off which is not the case with previous galaxy devices. hence even if samsung rolls out a fix they will simply make something similar to what we acheived with "screen adjuster". and dont forget you can still tweak the values in screen adjuster and find the best balance between black and smearing effect, the value "5" mentioned is suitable for me , it may or may not suit others.

so thay fu*ked up display also on previous phones and hide it behind the worse blacks really bravo samsung. I have my SGS4 from yesterday and have to say I see it clearly, the edges of grey lines are getting to purple colour. But I dont care because I can see it only if Im focusing on it. But for normal use you focus on text and what are you looking for and not to some grey lines right? So, Im rather happy with my super deep blacks...maybe some good AOSP/AOKP/Cyanogen will replace TW interface...
