I bought an used photon Q from USA, perfect state but I want to know if the screen is ok or damaged:
using the brightness at high or maximum value I notice a strange effect.. I see light color lines between every 2 line on the screen.
I easily notice this effect on gray pages, for example in settings.
For example If I have an uniform gray image on the screen, I will see between every 2 gray lines a little white line..
Using "screen tester" from market I can easily notice that it happen only with gray, other colors seems okay, but I slightly notice also in more complex images with complex colors..
Is this a problem of my device or is a "problem" of all photon Q screens?
No one can help me? :crying:
I would like to know if other photon Q have this problem!
It seems like the problem is present in all color combination, not in pure color like pure white, pure black, and pure red, green or blue.
When I mix 2 of that colors I get something like:
XXXXXXXXXXXXX
XXXXXXXXXXXXX
XXXXXXXXXXXXX
XXXXXXXXXXXXX
or
XXXXXXXXXXXXX
XXXXXXXXXXXXX
XXXXXXXXXXXXX
XXXXXXXXXXXXX
XXXXXXXXXXXXX
XXXXXXXXXXXXX
It seems like the screen can't make all 16million colors, and to get the correct color use different colors in the neighboring lines.
This problem is more visible with high brightness and looking at the screen closely.
(I try to use a magnifying glass and the problem is obvious).
Someone can check his photon Q screen?
You can go to android settings and see if the black -> gray background have this strange effect...
I need to understand if is a problem of all Photon Q or if is mine defective.. I have to decide whether to return the phone in the U.S. or if I get refunded the cost of the screen and try to change it by myself
Here is a photo of the issue: http://imageshack.us/a/img547/5474/uhkg.jpg
You can see that the "gray" background of the brightness settings is not uniform, you can see dark gray lines and light gray lines.
You can see this also without magnifying glass and with your own eye..
In some photos seems to see a grid.
it is as if the subpixel grid is not aligned or something similar.. :silly:
I only need to know if you have the same "issue" with the screen or I have a defective LCD, so I can decide what to do! Please someone can check his photon Q screen and answer?
Thanks! :good:
have you anything changed on the display settings (desnsity or something with the colors ?)
its hard to say, it could be a display issue but i dont know really here. mhm
Until I read this thread, I didn't notice anything wrong with my display, and now I see the lighter-colored lines too. I don't think it's anything that will be fixed by exchanging the handset, but it's also not that big of a problem for me, either (I have to bring my Q really close to my face to see the banding). I wonder if the issue is more noticeable on that particular handset, or if you have really good eyesight (or maybe a little of both)?

I was kind of thinking the same... perhaps the OP is expecting perfection even down to the individual pixels... and that is just not going to happen.
Remove the magnifying glass from the screen, should work fine
Ahahah thanks for reply!
but I can see the lines also without magnifier!
I used magnifier only to make a decent picture

Look at facebook icon andin the lower part to the left of the background !!!
You can see these horizontal lines also in your's photon Q screen?

If you look at it from a distance, I doubt they are very noticeable.
Honestly, if you're really picky about screens - why did you get a Photon Q? The screen on this phone is not the greatest, I think everyone knew that when purchasing it - they were not buying it because it had the best screen.

I didn't bought this phone for the screen, but I was expecting a decent quality for a 2012 phone.
This not seems a normal problem, some lines of pixels seems damaged or something similar.
The problem is visible also at 20-30cm distance from the screen, the colors are not uniform, the images aren't sharp and in some cases I can see these lines.
At 50cm of distance I can't see these lines, I do not want to look at my phone from half a meter away.
The bad lines colors that I see are rendered by the pixels, is not a problem of matrix or distance of pixel or similar.
I simply want to know if you can see these horizontal lines on the screen, for example in the facebook logo, at 10 - 20 cm of distance.
Perhaps there was a stock of defective screens.
If my screen is defective I'll replace it in the future, if the problem is the bad quality of photon Q screen I'll stay in peace.
I don't understand how it's possible that the screen draws these lines, it seems stupid! The phone can control every single pixel, why draw these lines? I have never seen similar issue in a screen, even in the worst

Well, my Q is dead so I can't really tell you. What I can tell you, is the screen is not the best. It's just "OK" in my opinion.
This is my first native Android device, so I don't have a ton to compare to... but reading about screen tech, this device is not on the bleeding edge by any means.

Yeah, they say that the screen is not good because of the "low" resolution compared to the full HD and HD ready display (galaxy S3, S4, htc ONE, ecc..) but they say that the quality is good for an LCD, images are sharp ecc.. ecc...
I found this image on google: http://cdn.gottabemobile.com/wp-content/uploads/2012/08/Motorola-Photon-Q-4G-LTE-Review-display.jpg
Here you can see the single pixel but these lines are not present. Now I try to take a similar picture (I don't have the original rom but the issue was present also with original rom, also with recovery etc.. so is not a software problem).
From 20 to 30 cm away, I don't see any banding on my screen, so it's possible that you do have a bad LCD, or at least a less than perfect one. However, from what I've seen of the problem from the pictures you've shared, if I had the same issue I would probably just put up with it, especially if the phone is great otherwise. On the other hand, what bothers me and what bothers you are likely to not be the same. So use your best judgement on whether the lines are bad enough to justify replacing the "faulty" device.

I have noticed exactly the sam effect on my Moto G. You need very sharp eyes to see this but with hight brightness it is there. Pure colors are not effected. Gray and light blue colours are mostly effected. I presume this is normal to mix different colours.
Does anyone get lines on their screen it seems to really show up on light and grey colors. Its weird because it doesn't look like it goes from edge to edge its just where there is bright colors.
I attached a picture, my display just goes nuts whenever I have it up because of all the grey. I can see the horizontal lines at around 15% screen brightness and up.
Perfectly normal on a LCD Display...have it on my Nexus 7 (2013), Nexus 5 and noticed it on other devices like the LG G2...not noticeable unless you´re VERY close to the screen...nothing too bad

I can't believe this is normal, this effect doesn't show up on my computer LCD, and when I have that picture up you can see lines from far away on my phone.
Okay...I see you´re coming from the Galaxy Nexus, just like me...muuuuch better screen imo despite the lower pixel density..
But very noticeable Scanlines might indicate a GPU or Screen defect...small lines, barely noticeable may be just the digitizer you´re seeing...Again: Only speculations
I noticed these lines on my N5, but they´re too small to capture on a camera let alone see from a distance...
You might want to RMA or try other Nexus devices out..
I am looking at the image on a 60" 1080p display and I can't see any horizontal lines. I must be blind?
when?
sorry when does it happen to u?
Same problem for me.
Horizontal lines.
Barely visible on white or black screens.
Noticeable on grey tones.

Ummm...... That is a SCREENSHOT it will not show defects in the display, only what the software is "outputting" to the display, screenshots will be defect free.

I'm having the same issue with my N5. Have you found out if this is normal or a hardware defect?
Thanks!
So the other day while looking at a picture I noticed some small red dots near my menu, I figured it wasn't a big deal but then I started to notice it some more and on black screens its red dots but on lighter screens its white dots. I've attached a picture to explain what i'm seeing. Any ideas on what this could be?

Here's a closer view of them, its really hard to notice them but there's some small red dots around the bottom screen.
stuck pixels?
given the pattern to them in a banding diagonal line, im inclined to think it might just be that. RMA

Is it normal to see some kind of vertical lines on or under the screen when you look at it closely from certain sharp angles and under the right lighting conditions? To begin with I thought my phone came with a bunch of light scratches on it but after examination there seems to be a pattern to them making me think it might be a part of the display. Probably a silly question but I didn't see anything like it on my last phone which was the Moto E 2nd gen.
I have it too i think it is just something for your system to see that you are touching the screen.

Okay that makes sense. The Moto E 2nd gen was only a 4.5 inch screen so maybe they are there as well but not as visible.

I agree with him that's your answer
Hi all,
i got a problem with my display.
The brightness/illumination on display when displaying content with white background is from what I see not correct.
A certain part in the middle of my display is clearly more illuminated then the rest. But only when showing the color white.
I did the diagnosis test in the menus and here it occurred again.
Does anybody have the same issue?
Is this a display problem so I have to change my phone? Or is this just a calibration problem?
Thanks in advance
I have the same problem on my z5 Dual. White backgrounds and the screen brightness increases. Not sure why this is.

Does it do the same in manual brightness mode? If so, you probably got a faulty screen .

By manual you mean adaptive brightness off right?
If so yes in manual mode too
Here i made a photo of my display.
I think you can see it pretty good

I have exactly the same white spot on my black Z5, even in the same location. Very annoying, especially when scrolling through Facebook, Twitter and other apps with white background. On my iPhone 6S which I also use the screen is perfect.

You got a bright patch in the middle too - interesting. Maybe you could take this picture again vertically (without tilt & finger smudges) in a dark room ? I never saw 100% uniform white on any LCD & Amoled mobile screen, but yours don't look acceptable.

But this is definitely a defect screen. The bright patch in the middle is really annoying when scrolling
I returned mine today, the bright patch in the center together with all other issues was just too much. Got an S6 Edge+ instead, same weight but much larger and much better looking screen.
I have the same issue, but Sonys repair shop say there is nothing wrong which I refuse to accept. See my reply in this thread: http://forum.xda-developers.com/xperia-z5/help/xperia-z5-backlight-unevenness-t3229903

I'm in Singapore and on my second Z5 and there is still this unevenness in the backlight. The first set was more obvious and in the middle which was really irritating. This second one has two minor spots but they sort of form a line to the middle of the screen. It's kind of disappointing that the QC level of this product is so ****ty. Two straight out of shrink-wrapped boxes!
They are also from two revisions; the tray is different on both of mine... on the first set it was stupid with the microsim and sd slot on opposite sides meaning you had to slide one in half way to keep the sim card in before putting in the SD card. The second one made more sense with both the sim card and sd card on the same side.
I'm still pondering if I should bring it down to the telco to make another change...sigh.
guys my z5 had display but no backlight, I have bypassed the "V" and "A" both fuses still theres no backlight can anyone help?
