Hello all,
many watch faces look amazing on the Zenwatch in regular (full on) mode.
But the watch is 90% or more of the time in ambient mode (I am using Always on for over 2 days of runtime).
And ambient mode is a different story. The default (Asus) watchfaces are typically pixelated in ambient mode and do not look so well. There are other (for example Puije ) ambient faces which look much better.
So it seems it can be done - but Asus is not doing it.
Is there any way to force better looking ambient mode on the Asus watchfaces? Or, is there a collection of watch faces (like Puije faces) which look good (better than stock) in Ambient?
Thank you for any pointers

There is a very particular reason for Asus to make its watchfaces "pixelated". It is because OLED screen technology is susceptible to burning out eventually. According to https://developer.android.com/design/wear/watchfaces.html#SpecialScreens the followig technique is reccomended to prevent this burning out:
When designing for OLED screens, you should consider power efficiency and the screen burn-in effect. When these screens are in ambient mode, the system shifts the contents of the screen periodically by a few pixels to avoid pixel burn-in. Do not use large blocks of pixels in your ambient mode designs and keep 95% of the pixels black. Replace solid shapes in your regular ambient mode designs with outlined shapes in burn-protected ambient mode. Also replace filled images with pixel patterns. For analog watch face designs, hollow out the center where the hands meet to avoid pixel burn-in in this mode.

Thank you for explaining. So are the nice(r) looking watchfaces going to burn the OLED out (sooner)? Puije has a "burn in protection" mode - is that a solution (I am using that)? Some Puije ambient mode watchfaces look (much) less pixelated - since I am not using the "Disable anti aliasing in ambient mode" of Puije. Or should I?
I do not really see the relationship between antialiasing and burn in? I thought antialising (or the lack of it) has to do with power consumption. Interestingly, most of the Asus watchfaces have the center of the hands filled in - while the guidelines suggest to have the center empty...

I'm not using the Puije watchface myself, so I could not be sure what this means exactly. I could only guess that with antialiasing you have larger adjacent regions of pixels highlighted. So the image shifting will affect only pixels located on the borders of these regions, while most of them will be highlighted all the time.

Does anyone know if there is a way to adjust the display's color saturation and color balance? While the screen is eye popping to look at, the colors are not accurate. They are distinctly warm and oversaturated. This is great for looking at icons, but not so great for photographs. I know the international Galaxy S II has something called "background effect" where this can be set to 3 presets with varying saturation levels. But this option is missing on the AT&T SGS2. I found an app called Screen Adjuster in the market, but that only lets you increase saturation or change color balance by increasing the intensity of the Red, Green, or Blue values. There's no way to turn them down.
So has anyone figured out a way to adjust this? Thanks.
bump. also hoping to find a solution for this but not having any luck yet
+1 on this.. I am a professional photographer and I used to use my I4 to present my portfolio. As of today I can't do that, or I have to do re-do my portfolio specifically for the SGS2's display. Which I really don't wanna do.
"app called Screen Adjuster in the market"
Thanks for this! At least with that the color temp is somewhat fixable, but overall colors are still terrible. As long as Samsung insists on locking these devices into torch mode we're just screwed. It's a shame that this didn't ship with several selectable profiles like the regular version (although I never seen it so dunno how good that implementation is.)
Working on hardware calibrated monitors all day and then looking at this phone is a bit jarring.

I totally agree! My wife's iphone 4 looks way better with photographs. To me, photos on this phone look cartoonish.

This would be great. Caartoonish is exactly what it it. However, we need to keep in mind these displays are far from professional grade. I won't argue that some software could help bring a small level of 'professionalism', however.
I just read around the web that the international version of this phone has Settings, Display, Background Effects to calibrate?
------------------------------
Well I checked out Screen Adjuster and it has the ability to change R,G,B values along with the brightness and Contrast ... so that's enough to for me to use me Eye-One Pro to calibrate the screen. I just need to put grayscale and R,G,B targets to the phone.
This should work just fine
can you post your settings when you calibrate it?
I also found this
Calibration Hack for Nexus One
Which I am now using. Since it has the grayscale bar built in. But this one requires Root access as you need to put the apk in to the /system/app.

Great find! Do you know if CM7 is a requirement for this? This may be the best option for color correcting the display.
I just realized that with Screen Adjuster, you can change the color balance by adjusting the relative values of RGB, then turn the Brightness down to compensate for the elevated brightness levels. Without turning down the Brightness, the black pixels are no longer black. So it's a pretty decent solution.
Just got Screen Adjuster, are there any recommendations for "optimal settings?"

I'll look into this - I'm surprised you find yours too warm, I think my phone is a little on the cool side - without a doubt bluer than my Infuse.
If it's supported by the I9100, I can probably find the relevant kernel interface.

Problem is... just like calibrating a TV/Monitor is that it doesn't have High Bias and Low Bias R,G,B. High Bias changes the whites and Low bias changes the black.
Also, unless you plan on using your display at a constant brightness level, you will get color shift in the lower end of the spectrum
For what I have done is create an 18% gray jpg and a 82% gray as well as a 50% gray.
ON MY display the whites is on the warm side... but there is nothing one can do about it, because the apps just don't have those value to change
ON MY display the blacks are also very warm...
I WAS able to use my i1Pro (spectrophotometer, unlike the cheap colormeter) to get it pretty damn close to 6500k in the Black and Mid-tone.... again nothing one can do in the whites.
I am 90% happy with the results (I'm anal, but I can't do anything with the whites!)
My settings might get you close to 6500k (most likely not.. because ever display is different, and from what I see here some are too warm/cold..etc).. My settings are to use with Calibration from the Nexus One thread, and they are set up to have a warm mid-tone
Red: 627, Green: 623, Blue: 665
Mind you that I also am using CM's 7.1 with the brightness custom level set to my likings...
But it's night and day difference (if you are looking for realistic color representation). A lot of untrained eyes like the eye popping colors, while a calibrated display is much more subdued.

I keep getting a force close after I install the apk. What version did you use? The app installs fine and will open but when I try to adjust RGB, I get the forced close. Thank you!
Anyone else have issues with screen burn in?
I am having some. On the right hand side the bottom bar has burned into the screen creating a permanent shadow of the bottom bar from when I was using the tablet vertically It is extremely noticeable on dark grey backgrounds.
Anyone else have this happen?
This is grounds for a return yes?
IMO this is unacceptable.
IPS displays can suffer from image persistance. It's quite well documented. You can either run a color strobe or display a white screen for a while to try to release the electric charge built up in and around those pixels.

It's not burn-in in the traditional sense...it's usually solvable by the above methods...whereas old-school burn-in on crt tubes was permenant due to the technology.
Ill have to do some research on this. Any suggested articles on this particular topic?
Or advice on how to prevent it like optimal screen time usage etc?
Hey quick Q, i bought a S3 on Wednesday, just noticed that when the screen is green ( or when browsing 0 brightness) that there is a faint whitish pixel that always shows up. Its not visible on black screens, red, purple, or blue.
Anything i can do? Or should i not even bother as its only 1 and how often does the screen go green.
There is no such thing as stuck pixels on AMOLED screens, only defective (either always-on or always-off) pixels or lazy pixels.
While it may sound stupid when related to what I just said, try the app 'Dead Pixel Detect and Fix' and let it run for half an hour.
It will cycle the colors very fast. It will most probably not work but it's worth a try.
If it still appears, try taking it back. Defective screens on a new 600$-handset is not very nice.
ah i see, but can you explain to me why it does not show up on a black screen/background? I just find it interesting and would like to know the reason behind it.

If it bothers you, just take it back to where you got it from and get it either fixed or see if they can give you a new one.
LCD screens use a white backlight illuminating the whole screen from behind. White includes all visible colors from near-infrared to near-ultraviolet.
To create the different colors they use crystals which are rotated by a power source in the correct angle that only a certain color (e.g. blue) is visible.
LED-Screens [*] and their derivates such as OLED get rid of the backlight and instead of using crystalls, replace each dot with a ligh-emitting diod (LED) which by itself gives light. However LED's have a big deficit; they can only produce one single exact color. So, similar as with the old CRT screens, LED's use multiple colors per pixel [**], these are the RGB colors (Red Green Blue). So each pixel is made up of multiple so-called sub-pixels.
If all 3 are lighted, they mix together to white, any combination in intensity (from 'off' to 'full brightness') gives you millions and millions of colors to display.
(It's easiest to see on large-scale LED televisions, just move very close and you see the 3 tiny 'lamps')
Now your particular issue is that a certain, due to one of several possible issues is not powered off or connected incorrectly; it is lightened at the wrong time.
So the reason it only shows at certain combinations is, that at other combinations you cannot see it due to the difference in color being too marginal or the other LED's also being off.
While it's unnerving, these issues keep arising during production. One has to keep in mind that one such small screen is made up out of thousands of individual light sources which can each be triggered individually to form millions of different colors.
Usually quality-control should get rid of such screens, but sometimes one slips through. I'm not sure what Samsung's standard for the S3 in regard to maximum defective pixels per inch or unit is, but you can (and should) always try to get it replaced.
[*] A lot of cheapskates sell LED televisions where in fact a normal LCD panel is built-in but they refer to the backlight source which in their case (and most other current productions) in fact is an LED source. It has nothing but the name in common.
[**]
This is not entirely true since structures such as active-matrix OLED (AMOLED) share LED's between pixels to cram a higher pixel densitiy in the same physical size.

Just picked up an AT&T One M7, and wow, the screen temp is incredibly warm compared to my G2 and just about everything else I use with an LCD screen. Is there an app/rom/kernel (or any combo) out there that will back my screen away from the warm tint? Thanks!

The warm tint is supposed to be correct and true to real life colors and what you actually see. Why would you want to stress your eyes by making the colors unnatural and harsh? I wish more companies would make their LCD's this way instead of the artificial over driven blinding harsh colors.
I calibrate my Nexus 5 with the SpyderGallery app. You just need a Spyder sensor... It isn't really a calibration in the operating system. But it will show the right colours opening images in the gallery of this app. This helps me when showing photos to my clients.

I wish manufacturers would give consumers the choice. Clearly there's a variance in panel manufacturing and factory calibrations, even from within the same display supplier. To me, warmer, yellow screens looks dingy and dirty, and not what my eyes are used to when reading web pages. So the warmer temperature may actually have the opposite effect on my reading comfort. Nokia has begun offering an in-OS setting on WP devices that helps correct minor variations - and I'd love to see other OEMs follow suit.
Hello,
Never had a phone with Always on feature so I would like to ask if is a normal behavior to see for a few seconds a clock image retention from AOD when the phone is unlocked.
I have LG V30 H930 EU unlocked model.
Been using a H932 with AOD since day one and have never seen any image retention issues from it's use.
It's not very visible, you have to look very closely and perhaps also have some specific colored wallpaper. It lasts only 2-3secs and then slowly disappears. AOD needs to be on a screen for at least 30-60mins I think.

But the AOD constantly moves.
As previously stated, the AOD on the V30 is not a static image, but a dynamic image, (it rotates to several locations on the screen at a certain interval). That should preclude it from issues involving image burn-in or retention.
Having said this, there is an app on the Play Store that Samsung owners use to combat burn-in on their OLED equipped phones. I don't remember what it's called, but you should be able to do a search by topic. The other thing I would recommend is avoiding having the AOD on it's bright setting. Its a bit too much, even in bright daylight, and it does increase the chance of image retention, IMO.
Bright setting is off, but the brightness of AOD at least on my end is dynamic and depends on the light sensor. This "bright setting" to my eyes do almost nothing.
Ok nevermind, probably I'm just nitpicking... I appears to be "visible" only on a pinkish part of the wallpaper. It's one of the default.
I have (what I consider) an annoying slow, fade to black when I turn off the screen. Perhaps your "retention" is the same, slow change of state for the screen?
Maybe we can call it this way. I'm coming from LG G4 IPS screen which is changing such things instantly obviously and I don't know what is "normal" for OLEDs. As i said, clock number from AOD after unlocking has its footprint for a moment on a wallpaper, slowly disappears.
The screen is otherwise pretty good if I cosider some horrible issues reported here or on reddit.
But still apart from this "retention" issue I found 2 more, but basically small issues described here:
https://forum.xda-developers.com/showpost.php?p=75657168&postcount=670
so don't know what to do.
I'm still within 14 days return/replace period, but I'm worried about worse screen since this is still a lottery.
Not sure what is your issue. Turning off the screen is doing fine. Just one quick "animation" and everything is off.
