Hi,
Got a new Moto Edge 20 Pro a couple of weeks back.
The display at low brightness has very noticable Faint White Lines and the display looks grainy, like newspaper texture almost like the Kindle Display.
At darkness, when the display refresh rate is set to auto, I can see the grainy noise and the white lines change when I touch the display.
Grey and White colors arent Pure Grey and White. When I use pwmfree 1.3 or OLED SAVER app, the white lines are almost gone (not entirely gone) and the grainy texture / noise increases.
Any idea whats going on, whether it is a software or a hardware issue ?
is there a way to get this fixed ?

The noise on the display is the nature of OLED displays. Or at least the one on this phone. I have a regular Edge 20, but they have the same display anyway. Same issue you pointed out: grain with certain colors and at lower brightness. And yes, I do get some vertical lines at the bottom of the screen. It's not defect, it's just the way it is.

I had an iPhone12 before this and that too had an OLED Panel, and I wasnt able to see anything like this.
And the Noise is not consistent. It's pretty freaking uneven and Its a total mess. To see the Noise completely, just open a 2% grey image or something and observe it. It's pretty abysmal. No way OLED displays are this bad.
I just think that Moto has crapped on its customers with a defective batch of Displays.
Also the situation gets better when you use pwmfree app.
The panel's gray uniformity is pretty bad. Im suspecting if this is a case of banding/dirty screen effect on oled screens, which is a defect and not a norm for an OLED Displays.

Ah, well, I haven't owned any expensive phones so I can't really compare to anything other than the Moto Z2 Play, which also had a grainy OLED panel. If I were you I'd be annoyed as well, but I payed a fraction of MSRP for my phone so I can't complain.

I have noticed a weird behavior with the display. forcing it to 60Hz by enabling power saving mode significantly reduces the grain and make the panel a lot more uniform.

on my display I have a vertical line slighty lighter than the rest of the display. Whole screen top to bottom. Anybody else same problem?
Sounds like a hardware fault to me, may be worth getting the unit replaced.

I wasn't sure haven't seen anything like this on any of my previously owned PDAs. It isn't a pixel problem. They show all the colors. It looks like the backlight is stronger. It's one pixel wide running top to bottom. And the difference in contrast is more pronounced in the darker areas. You can't see anything on white background but it is clearly visible on black or dark colours.

I'm not an expert, my conclusion is based on my time spent with my old Z1 ( defective screen, Sony service center agreed as well ) and my new Z1.
So here goes:
I bought a Sony Xperia Z1 C6902 around the end of last month. After coming home I almost immediately felt like there was something wrong with the screen.The display light seemed to be coming from the sides ( like underwater divers with lights).I had this yellow hue and slight tilts would produce drastic washing out + more of this mysterious "yellow hue" everyone's been talking about.The display just didn't seem uniform. Videos and pictures however seemed to display perfectly. A completely white screen would appear patchy.
After a lot of running around, going nuts and tweeting, I finally got my replacement Z1 today.
Now : Slight tilts DO NOT produce drastic washing out anymore.The screen displays uniformly now .The sharpness of viewing angles still sucks, and there is slight washing out, but only after you're holding it at an awkward angle.
HOW TO CHECK IF YOUR Z1 displays whites correctly.
Do this : Go to your service menu. In your device, open the dialer and enter *#*#7378423#*#* to access the service menu.
Hit Service Tests ---> Display
You will notice the 1st and 2nd screens match the yellow/off whitish tone of the settings menus. ( On a bad screen it will be patchy, on a good screen it will be uniform )
Now tap the screen 8 times
THIS screen will show you if your device displays whites correctly.
(attached pics of my replaced Z1's display test from the service menu )
Conclusion.
There are 2 things going on here.The yellow hue and and bad Z1 screens are two different issues, but not completely separate.
The yellow hue /off whitish color seems to be Sony's color config for the Z1.( check the screen i've mentioned above to know if your device shows whites correctly )
The bad screens are the ones that don't display uniformly and seem patchy ,have drastic washing out on slight tilting ( which in turn, seems to make the "yellow hue" seem worse, making people think they're connected.)
So,
Bad Screen : Patchy when displaying a full white screen, drastically bad viewing angles, not uniform, display distortion on even a slight tilt.
Good Screen : Decent viewing angles, NOT patchy when displaying a full white screen, uniform display.
ALL screens seem "yellow".
Sony's customer service here was SO SLOW and It should have happened sooner but after almost a month, I'm finally using the device I paid for.
Trust your eyes. Don't blindly accept that all Z1 screens are bad. The Z1 has a lovely display.Know the difference between the "yellow hue" and a defective screen.
Best of luck !
When you say patchy are you referring to like uniform patterns squares (pixelated within)? I see these pixelated squares for all colors in the screen calibration and the 2nd color was like very light patchy horizontal bars. I thought it was my thumbprints but no. I cleaned the screen before the test.

Nope, that's not what I mean. When I say patchy I mean a non uniform like display. Almost looks like there's light patches of water on the screen.

Not sure if it helps but my previous Z1 was a BH904
this one is a BH906
Hi,
Has anyone notciced un-even brightness across the screen at low light levels (for darker colors)? I thought it was just the nature of these OLED screens, but I don't see this with Galaxy Phone with similar display type, so I'm wondering if I just have a defective unit with bad display.
To test it:
- Do this at night (when ambient light is fairly low).
- Lower brightness down to the lowest setting (turn off auto-brightness)
- Open Chrome browser, and close all tabs, so that you get a blank dark screen with just the "+" icon. This leaves a dark gray background, just enough to notice if there is any uneveness in brightness.
On my unit, I see about 3-4 inches of bands/streaks of darker areas at bottom half of the screen. If I rotate the tablet, the darker areas stay in their physical location (so these bands become vertical instead of horizontal), so I know it's not a software issue.
I have a couple of weeks left before I need to decide on whether to exchange the tab, so would appreciate if anyone can help me verify if this is normal thing with these screens.
Many thanks, Tony.

I have notice a similar thing, mostly on gray - dark gray backgrounds, and not necessarily at lowest brightness (low enough though). I wanted to check about it on a couple of devices on display at retail stores but it's hard to test there.

Hi tonyc1,
Having had 4 of these I can confirm that this unevenness is normal on the 9.7" screen but was not present on the 8" model.
I went through 4 to get one that was reasonably even, 2 of them were pretty awful to the point that the greyscale was all over the place.
The unit I settled on has a slightly darker band in the middle of the screen and a slight darkening at the very top.
I owned the original tab s 10.5 and have to say the screen on that was more even and detailed, I prefer the former factor and speed of this S2 but the screen is a step backwards.
Hope this info helps.
Cheers
Thanks for the notes and confirming this is a somewhat common issue. I guess I will live with it for now..
I just got this phone and I am really disappointed with the colors on the screen. Everything looks washed out and dull. I have tried the color calibration and it still doesn't help. My screen looks nothing like the screenshots here, nor any of reviews I have seen. Any help or suggestions? I'm not looking for oversaturated colors or for the screen to be on par with higher end phones. I just want it to be better.
Orange colors appear more of a burnt sienna color and fair skin people almost have a bad spray tan look.
Colors are totally fine on my device. Yours may be defective.
Try increase contrast. Worked for me
I reset the device and the display is a lot better.

I also have the same issue with my screen, calibration is inconsitent and fluctuate between some orange tint, if I adapt it it slowly drift to get orange again. When I set all RGB values to 100 % it's more like a greenish tint that still drifts to orange.
I don't understand what's going on with my screen...
HEy guys...I`ve found it
Go to accessibility and search for color correction something like that and turn it off
Hey,
Just bought this phone used and I'm noticing slight imbalances on the screen, especially in solid colors.
It seems like subtle dark stripes from top to bottom every mm or so
Also their is a "grain" to the display in some colors.
When changing the refresh th this becomes more noticeable and 90hz appears to be much cooler in color.
Anybody else noticed such irregularities?
I'm not really disturbed by it, just curious if this is normal for a "flagship" screen
