An Observation - Motorola Droid RAZR

I've read of several owners complaining about how bright the lowest brightness is, and others (including myself) on the dark 'splotches' on the screen in very dark settings, only recently have I pieced the two together: Motorola purposely made the minimum brightness still very illuminated in order to try and hide these marks on the AMOLED screen. It's very annoying when these are visible, and it's even more annoying trying to read or accomplish any task in a very dark setting; the screen is still so bright that it hurts my eyes.
I hope Motorola fixes this hindrance in future iterations of the Razr/Droid series.

That makes sense
This makes sense. I too have noticed the dark splotches and I thought I was the only one who received a somewhat defective one. But for me, as long as I'm not looking at a super dark image in a super dark room I cannot notice them.
But thanks for the reassurance that I'm not the only one!

Does not make sense at all - how low would the brightness have to be to see those spots if they are only visible on black background in COMPLETE DARKNESS?
Yeah, you have just discovered America.

I have the same. I only see them when the phone is docked and in night clock mode, or when I'm running screen filter to cut the light when playing something in bed.

Never seen them. Not that big an issue if they're there.

If my brightness is set to minimum and it's nighttime, when watching movies, looking at pictures, or even just navigating around the OS, I can see them, they look like water-marks on the screen.
"you have just discovered America." Is that suppose to be an insult?

Oversaturated colors and blue tint, redux?

I've seen a lot of youtube videos of the galaxy s II and from what I can tell, the screen is still oversaturated like the original galaxy s, with the same blue tint on white backgrounds. Any chance this would be adjusted, or even have a user-adjustable option, by release? I'm guessing a majority of people outside of forums don't care and prefer the gaudy colors, like how they crank up the color on new TVs and everyone's face looks red, because buyers prefer it. But an option would be much needed for those not so inclined to the heavy colors. Another thing I would want is a lower brightness setting. LCDs get washed out but AMOLEDs can handle lower settings and still have good contrast. With that, the ability to adjust the minimum and maximum threshold for the auto-brightness instead of one predefined setting, as well.
I doubt Samsung (or any other manufacturer) would let you modify that much in the settings. The phone is not a monitor, however I certainly see the possibilty of changing those options (or at least some) once some kind souls will start messing with the firmwares and kernels.
*cough* supercurio voodoo color *cough*
If it involves *cough* hacking *cough* I think I will have to pass. And yes, there are less industrious people around here as well.
i am pretty sure that the sgs 2 will have the same same over saturated colours and the tint(looking at review videos).i am not a fan of amoled i do like its blacks but the over saturation does my headache i prefer ips to amoled any day. if it was not their Soc's i'd never have bought sgs.

Or the Nexus S general forum. Fingers crossed.
A challenging task for the devs here ...........
I only see a blue tint when I tilt the angle of the screen. It doesn't take much to see it and becomes more extreme the more it's tilted. Looking straight on is fine. I didn't expect there to be perfect viewing angles but tilting just a little the blue tint is really prominent. Easily viewed on a pure white screen.
Great phone, though I want to use the device to watch videos and two things bother me: the blue tint when not viewed straight on and the over saturated colours. The colour green is very oversaturated much to the point where I think there's green in the videos showing up that shouldn't be there! I know you can adjust the colour tones, that include warm, cold and natural. If the image looks too yellow/green then the cold setting looks a bit more natural on some videos. I would have preferred a proper configuration for adjusting the complete colour balance.
The screen is wonderful but is let down by these two things. If it's something that can't be helped then that's the way it is, but it would be great to have more control over the colour settings and if the blue tint is really a limitation of the type of screen/glass, or the first batch of phones have an inherent fault with the screen?
On thing that is also off is the gamma curve!
greys become dark too fast, shadow details are crushed, even though the screen has the potential not to do this. On the contrary, with such black levels, the panel should be able to show more shadow details.
I suspect this is a battery saving choice, rather than a screen limitation. I'd rather have an accurate gamma though.
Google will need to allow custom color profiles in Android soon!
My Galaxy S has much more natural colors than the S2 that I just bought. I can't stand the disney colors! Hope some developer will be able to fix that soon!
Is it just me?
How come you guys say that the SGS2 has bluish tint? While when I compare it to my SGS(speedmod) and my friends SGS(voodoo) my SGS2 has a yellowish tint to it? I'm a bit confused. Anyway I've bought it and my only complaint is the sound. Voodoo control plus please!
There is some degree of control (not much though) over the saturation in Settings > Display > Background effect.

The easiest way to see this is to view a white page/screen. Look straight on and then begin tilting the phone in any direction. The blue tint becomes noticeable and more extreme the more you tilt it. I wouldn't have a problem if it was only noticeable at extreme angles, but I do see it if the viewing angle isn't straight on. For phone use this is fine, not so bothered. Not so good when watching media.
Regarding the tint,
Also when i purchased the phone in may the gray was going into pink!
On later updates colors seem better! aswell i rember i posted a request in chainfires 3d drivers tread were i ask the guy kindly to add support for custom rgb mode nightmode tones...
So from his application if u play with nightmode function you can tilt your color as u like!

[Q] SGS 2 - low light reveals screen defect?

There are a few threads out there that have touched on this issue but none as far as I can see that deal with it directly.
The problem comes when you display a pure black screen in low light conditions. It shows that the AMOLED screen is actually grey / blotchy / cloudy instead of being pure black. Initially I thought mine had fingerprints or smudge marks on it, until I realised they were behind the screen. I guess I might have got a phone with a screen that was replaced, but the amount of people who have also reported a similar issue leads me to believe that it might be a manufacturing default? The blotches / clouds on the screen dont change, but exhibit a random formation as one would expect from a defect. It is also possible to see a very faint outline of light running along 3 edges of the screen.
Naturally this is a situation that doesnt reveal itself very often. But I as I use my phone a lot at night, especially reading ebooks or watching films, you start to notice it more and more where you have large expanses of empty black screen.
What I would like to know is how many people have got screens that exhibit this behaviour and how many of you have sent them in for service or had them replaced?
Is it a common issue and something that is to be expected from this type of screen?
You can test if yours has this problem using 'Screen Test' (its free) from the market place. It cycles through solid colours and patterns every time you touch the screen.
Just do it in bed with all the lights out P), give your eyes a few seconds to adjust and see what your screen looks like displaying pure black.
I'm very interested in everyone's experiences and any input or information you have.
Thanks everyone in advance!
ps: I came from a ZTE blade (OLED) which has a uniformly dark grey background when displaying pure black. I kinda expect this as it is a budget phone (albeit with a better than budget screen), but I didnt expect the SGS2 to be quite as bad.
Use "screen adjuster" from the market and set contrast to -60
i have never seen this black low light screen defect. but i am asking you people if any of you have noticed that ugly blurry shadows which are perfectly visible with low light, on white backgrounds especially. they look like marks above the actual display and make high quality images look like low resolution.. it is annoying as hell..
I have this. Noticed it one night when my phone was switched off and charging.
Sent from my GT-I9100 using XDA App
I also have this, noticed the first evening i used the phone...you can notice this during the screen wake delay, or when in a call if you cover then uncover the proximity sensor...don't know if it's a defect but sure it bugs me, i know many won't notice it and will say they don't have this...i will add that if u look carefully to the screen dimmed at lowest brightness in a low light (buy not dark) environment, like early morning, you'll see some "interferences" behind the image, also the darker/yellower left half screen is still visible in these conditions
These things shouldn't be there in a 500€ phone
Sent from my GT-I9100 using XDA App
Thanks for the feedback already.
@elmerendeiro: I have also noticed some 'interference' lines on my phone from time to time. I did a bit of research and it seems when your phone's brightness is set around 25 - 30% it picks up interference from either the wifi or 3g radio. Notch the brightness either above or below this level and you wont see it anymore.
I agree with you when you say we shouldn't be having these problems on such an expensive phone.
It bugs me too - if it wasnt for this i'd have to say it would be an amazing phone
Might give the Samsung service center a call and see if its something they're aware of and if they are replacing screens with this problem?

Screen Burn what to do ?

I got my hands on a Razr x910 and it has screen burn. what are my solutions for this? Can i order a screen from someplace on the web ? what are my options?
please post a picture, i ve never seen a problem like this in a so short amount of time
Do you mean like black dots when the the screen is black?
I thought only plasma screens have burn marks
There are a couple apps that can attempt to reverse it, like Display Tester, fixes the burn by scrubbing the pixels with white and black nars, try it, couldnt hurt

here is a picture of the burnt screen. its a yellowish tinge in the screen. whenever there is a white or light screen you can usually see them. However it doesnt effect games/videos, so its not to bad..
I ran that display tester and no luck!
I'm not even absolutely certain that's screen burn. AMOLED is kind of notorious for... inconsistent... colors (especially whites). And the RAZR in particular has some artifacts that are especially visible in the dark. They don't impair usage generally. But then the display I'm on typing at the moment isn't the best so it's hard for me to be sure how bad it is on your screen.
EDIT: scratch that, looked closer and I can make out the launcher icons at the bottom. That kind of sucks, actually.
its not to bad, and again only on light screens. I am always going to run a dark background so its unnoticeable. But when i run into some extra money ill just buy a new screen This place http://www.repairsuniverse.com/motorola-razr-lcd-screen-replacement.html
seems legit for a not bad price.
Might want to turn down your screen-on time as well. The only other RAZR I've seen like that was the demo unit at the Verizon store & its screen is on all the time.

Whiskey Tango Foxtrot... I've never heard of this on a mobile device, a tablet, or a laptop. Although cheaper LCD TVs (like my POS Westinghouse) can have it happen. An impractical solution would simply be to leave it off for a few days. But, that's not going to happen with a phone. If you can find a video of static... like a TV screen on a channel with no signal... and can have it run in a repeating loop, leave it plugged in and run it over night. The random white/black pixels will clear out LCD burn in. It might take a few sessions.
There's an app called JScreenFix that can be used to exercise the display as well. This issue was a problem on the first generation Fascinates. The samoled screens would retain the image of the status bar clock or the whole status bar.
Technically, it's not burn-in I guess, it's more like pixel degradation in certain color spectrums.

Are you having stains on the screen / burn-ins?

Do you have such stains? I hear this is normal among AMOLEDs.
welcome to mass produced (aka economically viable) OLEDs...
Some patterning or colour patching is inevitable even from new. Blue or Grey backgrounds tend to show patches up more. Very low brightness shows a greenish cast on the left of the screen too.
It took more than a decade before LCDs could be produced in volume with a very low dead pixel yield.
We have a dozen GS2s at work and they all have minor screen issues. From new. They do get worse or even change position over time (many months) as the pixel level elements shift in luminosity.
Also note that if the phone is warm, the effect lessens.

Thank God I don't have dead pixels. At least this patch I got is visible only on dark-gray / medium-light (so-to-say, idk) brown. I'd rather have that than dead pixels .
Actually, if I start Screen Test, the patch is visible on ALL colors. On blue/red/green, it is less visible. On white, it is most visible. Also, when displaying full whites, the color is not homogeneous. Vertical and horizontal lines seem to be present ALL ACROSS the screen. These lines are visible on white, yellow and such colors.
At least I don't have ghosting effect and the whites are actually white, not yellow - as it was on Gingerbread (yeah, software problem, eh?).
So... the patch appeared to have vanished after running the fix (which rapidly ****s four colors) for half an hour, because the screen was a bit warmer... and as it cooled down, the patch has shown its face again. Oh well...
the galaxy note and s2 super amoled screens are prone to burn ins, very common, you need to eliminate risks involved.
Turn off auto brightness, lower the brightness level, shorten the time youre screen stays awake for, and if youre using themes, avid the blue themed ics ones, although they look nice, the blue themes are one of the biggest culprits of the burn in issue and before ya know it youve got a battery image burnt in.
i notice it looks like you have a blue theme or something, my mate had same issue, what can ya do, its a pain and well probably all suffer it, whereas htcs dont have the issue, they just suffer dead pixels a lot, but hey, id soone have slight burn in than dead pixels i guess

F*** !
MIUI uses white & orange. Are those colors dangerous, too?
I mean... what colors should I avoid the most? Besides blue - I get it, it's bad (again, F***).
Anything that turns the RGB elements hard on (!). So high brightness only and white is worst as this is RGB full on, then pure red, pure blue, pure green. Cyan, yellow and magenta are less risky. In theory.
In practice and the real world, just keep the brightness down a little and you'll get years out of it. And save battery - the screen is THE major power consumer...

+1 absolutely right, follow these simple rules and all should be good.
White requires all three elements (RGB), right? Blue = B. Which one should I stick to...? My logics tell me blue, but I hear AMOLED's blue color is so pure because of a compound from algae (rofl) and it wears off more quickly (if any of that makes sense).
Cyan, magenta, yellow... Yeah, I don't have that on AOKP, lol. And neither would I want a yellow theme. Magenta would be nice, though.
RGB... hell, those are the primary colors. How about we use black, with polarised glasses? That'd be a good deal, since I wear glasses, lol.
Seriously, guys, what do YOU do to make sure the screen doesn't get damaged over time? Don't tell me you're using a yellow-black theme. And setting the screen brightness to 50% or more is required outdoors, so...
-----
I just went to a showroom today. Seen the Galaxy Nexus there. It's on, with the brightness set to maximum, 12 hours a day, and it's been like that ever since they put it there - more than 3 months. Seeing anything strange here?
well, as a rule i dont have wallpapers that have bright vibrant colours, i find it annoying and painful on the eyes, and if you have shortcuts on the homescreen it gets to looking messy, so i stick with dark colours, to be honest most of my wallpapers are black or almost black and my brightness is set at around 20%, and i dont struggle to see it outside in sunlight or anything, but this is just my prefernce, im sure everyone has different tastes, i think you should just enjoy your phone and use it how you wish, but try to avoid having it too bright, it should be ok.

I'll stick to the stock AOKP theme (blue, that is); but I will be careful not to raise the brightness above the point of 50%. And even if I do, I guess setting it to the maximum point for a few minutes (when the sunlight is very strong) wouldn't hurt...
Oh and mind archiving your black and dark wallpapers and sending them over to me? Please (I'm always happy to pile up such wallpapers)

Display not TRUE BLACK ?

Hello,
Im Using Amoled Smartphones since the Galaxy (i7500). They all were always showing at 100% Brightness for Black parts of a picture a true Black like the Display is OFF.
If you put the Brightness to 100% and go to an complete Dark Room and open an Black Picture you see some Gray/Yellow Tint on the Screen. You can compare this good by locking the phone to see the Screen OFF and than unlock it to view the Black Picture again. You should see a huge difference. Hope to hear from your experiences.
I've seen that already on the S1 when abusing it a a nightstand clock.
Best guess I've heard is that the (AMO)LED screen leaks some luminosity to other pixels in the background which is then visible as a very faint glow.
However I rather believe that the AMOLED are not truely off but rather get some leak voltage and thus have a very-very-very faint glow (like one photon per second xD )
That would explain the black spots most people seem to mind on AMOLED when on minimum brightness with a black screen; they are truely off or without insufficient leak voltagage (LED's requie a minimum voltage to work).
AMOLED production is somewhat complicated (very thin layer of silver as a power source and a control-layer) so I wouldn't be surprised if the above is true.
Nothing is perfect, especially not a rather new technology.

Yeah so I was wondering why it does this little/ hard noticeable yellow/gray tint on a dark room...
There is no Backlight... Unfortunely i Sold my Galaxy S2 so I cant compare it.. But im Sure it wasnt like this
I have this on my gsiii and also on the Gnote... I think is due to the pentile screen
I had this on my Fascinate but realized it wasn't a big issue. Definitely more noticeable on my Gnex but it also has more pixels so that could be why you see more light. I wouldn't call it a problem because the majority of the time it's absolutely unnoticeable. Each pixel has so have some sort of voltage to be ready to react to changes. Turning off/on completely each time light is needed might waste battery.
P.S. I'm noob at displays but that's my theory.

I was curious about this issue as well. It's my understanding that OLEDs do not produce any light in their inactive state.
Regarding your theory, I wonder if it's similar to plasma displays. Even though plasmas are capable of true black (they do not use a backlight) The individual plasma cells have better response times if they aren't fully discharged on blacks. So they have a faint glow that comes from the low power they are using to keep the pixel charged up and ready to go when a color change is needed.
This actually costs a little power though, rather than saving it. So if thats what they are doing, it is for screen quality reasons so that movies and other things look better.
Did some Googling and I couldn't find much information, but there is talk of delivering pre-charge voltage to the OLED pixels to improve response times. So it could be that they are indeed similar to plasma displays in that respect: Capable of true black, but the benefits of not using true black are too good to pass up.
Are you SURE the picture is actually true black? By that i mean pure 100% black in an uncompressed image? If not then you cant expect the phone to display true black. A JPEG of black may not be enough.
My screen it totally off when displaying true black.
I can confirm the screen showing a faint glow on S3 with a true black screen.
Use Firefox with Fullscreen extension (Chrome and the default browser don't seem to have fullscreen mode yet) and go to http://d4f.pf-control.de/black.html
That's rendered on the phone so we can expect it to be the blackest black an app can produce, however in a (very) dark room you'll see a very faint glow coming from the screen and you'll be able to see the black spots (truely black) that people keep complaining about.
The theory about it being a precharge voltage does indeed sound plausible since LED's have a certain reaction time which unfortunately cannot be compensated by e.g. Overdrive as is used in LCD screens.
Note that the S3's "black" is still far better than any LCD.
No mine is still jet black, no light at all.
Go to a COMPLETELY dark room and make sure the screen is actually turned on when on the website (not timed out).
Then take a long-exposure photograph of your phone (still make sure the screen is turned ON!).
I don't have a long exposure camera, but the room is completely dark and my eyes have adjusted, there is no light.
All sgs3 ( as sgs2) screens emit a very week glow on a black pictures ( with the screen on )
Sent from my GT-I9300 using xda premium
It would seem to me that the 'ink spots' many have are not overly dark spots at all, they are what the screen should be. My screen emits no visible light when displaying a true black image, at least nothing my eyes can see, even at the edge of my vision field where light cell are most sensitive. My screen is on maximum brightness.
My screen has no patches, no streaks, no spots, no pink or excessively blue tint. I guess i have a screen thats as near to perfect as they get.
yes there is very faint glow indeed making the screen a bit greyish instead of pitch black

I don't think anyone is trying to paint it as an issue that needs to be resolved. It's more of an odd technical mystery rather than a real problem. The blacks are still extremely deep on an AMOLED, just like with Plasma it puts LCD to shame in that department.
