Q: Black spots on screen? - RAZR HD Q&A, Help & Troubleshooting

Just noticed this today. When looking at a black screen I see a decent amount of blotches on the screen. I looked it up and it appears to be normal at least on the gs3. I wanted to see if anyone else has it on their RAZRs.

Hi, I already mention that in another thread, but yes I have the same issue on a dark screen on very low brightness and low ambiant light. The phone is usable but it's a bit disturbing to my eyes. And yes it's quite the same for the GS3. Must be from the amoled tech...
But the other thing is when on a solid green or blue or some others colours screen, like the fb loading page, I can distinguish dark stripes on the screen, it seem the the amoleds motorola uses aren't as good as the ones used from samsung IN the samsung's.

yep. totally normal for these screen types. The original razr had tons of them.

Welcome to amoled guys...

The contrast ratio is terrible on this phone

Forget the bleeding lcd edges , its the horrible contrast on this phone that will probably cause me to return it.
After coming from the inky black Amoled screen on the Nexus s , this is the most disappointing aspect of otherwise top of the line phone. You can't get a true black on this phone , the best it does is dark glowing gray. In fact anything with a black background looks gray , not total absence of light Black.
I realize that this phone has an LCD screen not an amoled screen , but I never thought the difference would be this pronounced. Example : when I power up my Nexus S the screen is pitch black and when the white Google logo appears , it will appear to floating in space in a dark room. The G2x display will put off it own light, making it very visible in a dark room.
Deep blacks are awesome but I find this screen better in other areas over AMOLED/SAMOLED IMHO. You have to pick what matters to you. I don't spend a ton of time looking at blacks so doesn't bother me

Agreed with you sir. The colors on this phone are awesome and I come from a Galaxy S 4G.
Its up to but every G2X I have sold out my store as well as mine the screen looks great. I am loving this phone for everything it has. Way better then my N1.
There's nowhere you can compare contrast of AMOLED because it's unlimited.
However, I think the black on G2x is a bit "darker" than my MT4 (good screen).

Agree... My moves encoded to WVGA 800x480 @2500k bit rate look great or just as good as my SAMOLED.
The blacks on AMOLED will always be darker than the blacks on LCD that uses backlighting. The blacks on amoled doesn't have light behind it so its gonna be darker, because there isn't a light source lighting up behind it. This comparison doesn't make sense. If you compare the GX2 any other LCD display on a phone it will out shine it hands down.

I am coming from a Vibrant and find the G2x display easier on the eyes. Yes the blacks looked better on the S-AMOLED but the colors are more natural on the G2x. However what I find to be most important is text look a lot better on the G2x display than the Vibrants Pentile display. I don't have to zoom in anymore to read text on webpages like I did with my Vibrant.
I have a thunderbolt and a nexus s also. The nexus s just sold on eBay. As previously stated you can not compare the blacks on a nexus s with the G2x, two totally different technologies. But compared to the thunderbolt the G2x shines. And the G2x has more clarity and better whites. When compared to the nexus s. G2x has great viewing angles. Over all a great screen, once you get past the back light bleeding.

My Video Review - One S vs. iPhone 4

Hey guys, I did a lengthy review of the One S and iPhone 4 - Apologies for the lighting, the camera I was using wasn't functioning properly in bright light so I had to lower the lighting in the room. However the video is emphasizing the OS' on both handsets and YouTube will allow it to go up to 720p streaming quality.
Clearly, there can only be "One" winner

I almost quit your video when you talked about the screens...
Under 1.5' you CLEARLY see the PenTile crap on the One S. There's no way to see a damn 1px line on that phone, it will display a dotted line...
Otherwise we have more or less the same thoughts about our phones.

Yeah if you know about it, you'll notice it.
However most consumers aren't aware of what a Pentile screen is, so they'll hardly notice it unless they're being told to look for it.
Honestly it's only an issue with home screen icons and some text when zoomed out. Video and pictures look crisp and clear as day, as do games. The whites do tend to be unbalanced, but that's more or less the blending of S-Amoled and Pentile. The Amaze, which is non-pentile and sports an S-LCD qHD display, definitely is the sharper of the two displays. But the colors and lack of any screen bleed (which you get on the Amaze) makes the One S tops in comparison. I'm a fan of the retina display, I'm just not a fan of the screen size, and I emphasize that in the video.
Thanks for watching.
Can you explain more about pentile. I don't see what so bad about it.

It still a PenTile screen lol... But if you don't notice something wrong with the One S you will certainly not see a problem with the GSIII since the resolution is much densier.

Yeah I would advise that as well.
I never noticed it until I read up about it, then it was a never ending mission to analyze sub pixels. It got to the point where I had to de-program myself from noticing, and since the One S does have as vibrant of a screen as it does, I've been able to overlook it.
Though I agree that in comparison to a non-pentile like the Amaze, you will notice it. In comparison to Retina, you'll definitely see coloration issues with the way the pentile portrays whites.
With that said, I really don't think it's as bad as people make seem, specifically on a 720p screen. I never noticed it on my G-Nexus, though I did get quite annoyed with the yellow/blue tint/hue that the whites put out. That bothered me much more then pentile, bar none. To each their own, everyone has a different set of eyes and will see things differently. In a way, I'm beginning to like the pentile because it makes icons and text come out a bit sharper, and just seem more comfortable for my pair of eyes.
The Amaze, and even a display like the G2X's with IPS really had no problems with the jagged edges and such on icons, and though the SGS2 Hercules has a 480x800 resolution, it was non-pentile Super Amoled Plus, which imo was the best in the market for that specific resolution. But where the Amaze was good with rendering smooth icons/text, it was bad rendering blacks and dark colors, because of the S-LCD screen bleed that was prevalent with the capacitive button lights. Once you turn them off though, you won't notice it.

Anyone else notice a green / yellow tint when brightness is low?

Just like the subject says. Anyone else have this issue? When I set the brightness set to the lowest my whites have a green yellow tint to it. If I set the brightness to halfway or full it completely goes away and my whites look white.
Sent from my DROID RAZR HD using xda app-developers app
this is just a normal trait of super amoled screens, just like how amoled have a hard time displaying whites (kills battery fast due to the display type)
I'm somewhat used to it now. Doesn't bother me at all. Plus, the peachy color isn't as hard on the eyes.
Sent from my DROID RAZR HD using Tapatalk 2
Hello, I did not experienced the change in tint because I'm slightly colorblind but there is something that disturbs me a lot, i'ts the fact that with a very low brightness, using a night mode app, on a dark or black background I can see several daker spots on the screen. I checked on a GSIII and you can also see some but it's less disturbing.
Anyone have this problem?

Note3 AMOLED Screen Quality *edit: tested 6 devices so far*

hi,
i just started this thread to get your opinions regarding the display quality of the note3!
i have to admit upfront that i'm a hypocrite when it comes to amoled screens, so far i had to switch all of my amoled devices a least 5 times until i got a unit which satisfied me. done this with the first note, and also with the second.
as far as i can say the screen of the note3 is the best i've ever seen (by far better black-levels as note1 and note2), although i also identified a few flaws as well:
the color RED has very bad viewing angles: when tilting the device a little bit the color gets orange immediately.
try this by enter *#0*# in the dialer, and click on "red" then tilt the device. let us know how "your red" is, thx!
the gamma of the screen is totally screwed: can see down to "1" in gammatest.png:
the disadvantage of this is that you are actually able to see dark grey screens which you should not.
on the left side of the screen border there is a small strip which has also more gamma then the rest of the screen, in menus etc.
this is clearly visible when its dark around. also only visible when at least a little grey is to display, pure black is ok!
this week i will test one or two more note3's, just to have a comparison and to determine if the quality spread is as big as with previous devices. for note1 and note2 the differences between devices were really huge. some screens were near to perfect, most of them had flaws with color unevenness.
what are your impressions?
and: do you care?
regards,
markus
edit 03.10.2013:
just got my second note (this time from amazon.de): the screen is considerably better!! the "more gamma" strip on the left side is non existent on the second device, in gammatest.png the screen is much more uniform! also the red viewing angle is better, it still fades to orange when tilted, but not as much as with my first device!
conclusio: the big differences in screen quality are still existant, it's still luck of the draw if you get a decent one or not...
also the general build quality differs: on the second device the pcb is not exactly in the middle of the casing, the camera hole is not centered in it's protrusion, and the power button extends a little more out of the casing.
again, i may be a "little" freaky about this things, but for > €700 I want to have a decent device!
screen quality is very important for me, because i read a lot with the device, especially in dark environments where the left gamma strip i mentioned was really annoying! i also showed this to a few colleagues of mine, and they agreed.
edit 04.10.2013:
another finding: when CPU load is high, the brightness jumps between a lower (darker) and a higher (brighter) state, even if brightness is set to manual: both devices show this behavior, although not exactly identically: my first device needs more load to start with this (it takes longer), the second one starts the dimming relatively early.
how to test: load a stress test tool (cpu prime benchmark from google play) and let it run, set the brightness to manual maximum and wait.
you will see that after a few seconds the screen will go darker, and will switch between this states. this is independent from the brightness level, it is only better seen at maximum!
i guess this is some power and/or thermal limitation (when more cores are under heavy load), it would be interesting how this kicks in in summer when ambient temperatures are higher...
edit 25.10.2013:
just to let you know: i'm now through 6 devices, all of them had display flaws in terms of uneveness.
a issue most of the devices suffer is the lower dark half of the screen: on 4 of my 6 note3's the lower half of the screen has been signifcantly darker then t´he upper half,
one had a very bad gamme increase on the left 2mm, one had a bad gamma increase on the top 2cm. 4 had a warmer white, two of them were more cold (more blue). could be due to missing or wrong factory calibration...
what is gone is the "blotch issue" i had with sgs2, note1 and note2, and: black is now really black!
but on dark grey levels the uneveness is clearly visible, look at the attached "gammatest.png"
this shows the lowest grey tones. and should be a very visible gradient from top to bottom.
go in a totally dark room, open the pic, zoom in max, and navigate to the top left corner. then pull the
picture down, and look how the numbers fade. for example: "6" should be at the same brightness level on top
and bottom of the screen. it definitely is not...
go out and test for yourself, and post your findings!
Hi there, I should be receiving my N3 next Wednesday. Are the blacks the 'true blacks', as in taking the phone in a pitch black room and blacks cannot be seen?

OLED screens are the only ones I know of that can get true black. With OLED the pixels make there own light so no back light is needed, thus black pixels are not being used at all so a black image has a nice inky black color. You notice it the best when you have a colorful picture with black in it.

sorry, but this is a wrong statement. all amoled screens so far were NOT totally black, even if you displayed a totally black image! the reason is that if the screen is active the display controller is powered (which is the case when displaying a black image, and not if the screen is "off") which can be seen as a faint and VERY dark glow. you can only see this when the room in which you are is totally dark, and your eyes had time to accommodate. to make it worse: on all AMOLED devices i've seen so far there were patterns (like hair lines and blotches) in this grey glow, due to the manufacturing technique used (lithography).
see for reference:

and so on...
so the question of cd993 is reasonable!
answer: note3 is the first device where i cannot see this dark glow, even in a total dark room! so a big improvement on this side. not sure what they changed, but the glow is definitely gone!
Red turns orange here to, but it doesent bother me as the screen is nice overall. Much better than my note 2
Red turns orange when screen is tilted, yes. Black are true blacks in Note 3. If you go to a pitch black room, and display a completely black screen in Note3, the phone will blend in and disappear.
Thanks guys, cannot wait to receive my device!!

Please make a quick guide of what to test and what to look for on a new note 3, in order to decide whether or not to return or warranty claim. Basically: On arrival, what would you check for, and what result would make you return it and get a replacement? How much of any issue would be ok for you to keep it..?
N3 screen : brighter and look better than Note 2 and S4 but still can not compare to the best IPS screen about white color

You'll do that with any Android phone whether LCD or AMOLED because their screens aren't individually calibrated (iPhone's are). So there's some degree of acceptable production tolerances that means all built won't be identical. So whatevery you went through before you'll go through again with the N3.
Oled = true black
LCD = true white

Today I got my N3 and all I can say its SUPERB!!! Abs everything
My only concern with AMOLED is the blotches that show on a grey screen in a dark environment like the first time I noticed it using Facebook. I had to replace my first Note II and even the second has some blotches but not quite as big and bad.
I've attached a grey background for your convenience to see if your AMOLED has blotches. You'll need to be in a dark environment like reading at night without the lights on (simulate by going into the bathroom and turning off the light).

Pointing out to OP that the leaking light on the Note 2 (and s3) is extremely reduced in the S4 and Note 3 - you should not compare the Note 3 with the Note 2 in that aspect.
Black wallpaper on n3 = better battery life then?
Other than seeing imperfections in impractical situations, is there anything about the display that is actually bad in normal use? I mean do you see whites on this phone and think, hmm that's more of an off-white or is it like so small in difference that you need a color spectrometer to prove that it's not "true" white?

I know what you mean. I had that on my note 2. Not so on my note 3. When I open black screen in a pitch black room, the phone becomes completely invisible as it blends in perfectly with the dark. And yes, I'm not exaggerating. It's the deepest black I've ever seen on any display, it's like the phone is actually turned off.

Hi Guys!
Need info about PURPLE SEMARING. Does the Note 3 has this issue? Because all the S4 has this semaring issue although it has a pitch black. Please confirm this purple smearing. If it's totally pitch black and without smearing it will be the perfect screen out there
Thanks guys! :highfive:

[Q] Screen Quality

Hi everyone,
It's my first time using a Nexus device.
I just switched from Samsung Galaxy S2.
With the samsung screen, the black is a real black whereas in the Nexus the black shows the backlight of the LCD (or however it is called now) screen so there's this white glow coming out when it supposed to be pure black screen.
I'm not referring to when the phone is off, I'm referring to when it suppose to display pure black background like when using the Daydream clock feature.
I'm not complaining, I'm just trying to understand if this is how it supposed to be
Thanks

It's normal. Use this for awhile and then go back to the s2, I have one too. You'll see how much better this screen is.
I agree that sharpness and colours are amazing on the Nexus but it's not the black colour / contrast I got used to from the S2.
I came from an S3 and I love the screen quality. I can actually see my phone in daylight.

samsung uses samoled screens, the blacks are blacker and the colors are more vivid. but, samoled screens dont show the real colors, they are much more overly saturated. oh, and black.. samoled dont light up pixels for black, thats why it seems blacker.

I could see as well with the S2
Anyway, as I was saying, I'm not complaining or anything... I just didn't know if the black I was expecting to see on the Nexus is about the same as in the S2...
Unfortunately, I must admit that the S2 presented a much deeper black and the Nexus 5 displays white glow rather than black.
IPS != AMOLED
S2 -> AMOLED. That's almost pure blacks and too saturated colours.
N5 -> IPS. In the N5's case, pretty accurate colours, but with background light, cause the tecnology is like that. You're not gonna get black blacks with IPS. The panel is quite a lot better in every other aspect though.
thanks @Molitro
I agree that besides the blacks, this screen is amazing
As others have hinted, only Oled screens can turn their pixels off complely (0nits) and that's why they can do cool things such as active notifications on the Moto X. When looked on head on the black levels of the Nexus 5 IPS screen are quite good compared to other non Oleds. Infact it out right destroys my desktop and laptop Tn displays in that regards.
