Screen quality issues

Anybody else having screen quality issues? First one(left) had a blueish tint and even though color representation is correct on the replacement, it has banding issues that are really noticeable when the backlight is low, so hopefully I have better luck with the 3rd.
Both phones are set to full brightness

I made a similar thread a while ago: http://forum.xda-developers.com/showthread.php?t=1295438
Long story short, I returned it, got one that was slightly better (less overall streaks, but one bigger one in the corner) but that overheated constantly. So I swapped that one, and this one is perfect. Not a spot on it, it looks as even as an LCD.

Same here indeed. I see it as more of a grayer color but the banding is very visible, especially in Tapatalk.

Same here, I had some gradient streaks especially in the notification curtain with low light etc....bad display. Returned mine and the new one is perfect. I guess some are just better than others but definitely a defect.

Lines on the screen

Any body else has this issue? I have thick vertical lines at the bottom of my
AMOLED sreen on the Galaxy Nexus.
They only show when the screen brightness are on low.
Should I get it changed under warranty?

This is pretty common with amoled screens, I wouldn't worry about it, its completely normal, and is only visible in dark rooms with brightness on low. Just be glad you don't have the blobs as well like all of the T-mobile Galaxy S2s have.

Cheers cbutters

yup. Mine is the same. Any replacement would likely be v similar. Forget about it.

I still think it's b.s. that for this new "Super AMOLED HD" screen that they downgraded from RGB and went back to pentile. Granted, they increased the resolution & dpi...
Apparently though, we'll have to wait until the next generation Samsung phones(after the Nexus) before they'll give us phones with "Super AMOLED HD Plus" that will be true RGB with high res & dpi.

SAMOLED. Just the way it is with whites.
That's the tradeoff for ridiculously black blacks.

I have a wide lighter coloured band horizontel across screen. Can see it when scrolling on lowest brightness. Auto mode in dark room etc. Cant see the vertical bands normally. Your eyes fix on the horizontel one while scrolling though. A replacement unit might be worse though. Grrrr.... ? Seems they all have these lighter or darker bands to some degree.

[Q] Color banding ?

When running LCD Tester i noticed color banding on the gradient color screens.
I can also notice this on the default UI of sense especially on the grey buttons.
It looks like in this picture (on the keys)
BTW it's not from my own phone, it's just an example of how it looks in real life on the screen of my One X

Hey,
if the banding can really be seen on the screenshots, the assets just aren't better. But if it is not, it's either the rendering or the screen itself (trying to figure out which one it is atm). To be honest I fear it's the screen itself.

The screenshots aren't from my actual phone, but i used them because in real life on my One X screen it looks like the screenshots

I have this banding too.
You can see it in a completely dark room on the settings screen of quickpic for example.
If you do a screenshot of it an look the picture on the PC you can't see the banding.
EDIT: After Update to 1.28.401.9 the steps from the banding are thinner and better (use quickpic settings page)

Made a screenshot of the Quickpic settings screen,
you can clearly see the banding, so its the software.
Haven't seen any banding issues on the HTC One X yet.
See pic where I increased the contrast:

[Q] Top part of the screen brightness issue

Hello everyone. I'm new here
I'm a new user of the LG G4. Quite happy with it right now. But I have a problem that I'm not sure if it's an issue or not.
On the top side of the screen (notification bar) I see a brighter light on the top that diffuse down (I don't know how to explain it)
I tried to take photos of it, but it doesn't appreciate too much. (I tried editing the contrast in the first one to make it more visible)

I wonder if anyone have this issue too, if it's normal or not. Thanks in advance.

Lol. This is by design.

That could be screen bleed where the LCD isn't bonded properly and allows addition light in from the backlight. I would compare with other G4s and get it replaced if needed.
If they give you crap about returning it just tell them the headphone port is randomly staticy.

Try to test it with full black baground with dead pixel test app from play store and on dark room.
Before try this go to settings and do the navigation buttons invisible to dead pixel app to test all screen. If you see very much light bleed then you must go to replace it. If you no then keep your phone and n'joy because you can say it normally. Many ips screens had this bleed.
If you don't want this your only way is Amoled.

Thanks for all your answers. I wasn't sure if that was normal, because I come from a S4 with Amoled and didn't have this issue. But for what I'm reading, it is normal. I think I would try to find other G4 and see if that happens too.

I have an LG G4
Funny thing is last night i noticed the exact same thing when i realised all the icons on the notification bar had burnt into my screen up there too which got me worried, maybe its all LG G4's maybe just ours but im not happy at all

Need help....Washed out colors

I had downgraded back to KitKat and had it setup exactly like I wanted it and had been using it for a few weeks. All of a sudden my screen would become washed out. Kind of like it was stuck in reading mode or something like that. Sometimes it will correct itself on it's own or if I enable then disable grayscale mode. If that doesn't work, then I have to reboot. After being locked for a few minutes though, it gets washed out again. I decided to go back to Lollipop to see if that fixed it but it's still happening.
What could be causing it have washed out colors?

Can you screenshot what you're talking about? And why would you want to be on KitKat?

Do you have the adaptive display enable?, is the rgb sensor blocked?
John.

I was going to try and get a screenshot but it hasn't done it again. Anyway, I just traded it for a gaming laptop today so doesn't really matter much anymore. Thanks for the replies though!

So, I got my tablet back and I have some screenshots of the issue available. Hopefully you'll be able to see what I talking about.

I believe it's hardware related. I was holding it at the bottom right corner when it got the green tint. Grabbing the bottom right and top left corners and bending slightly on the back of it causes the green tint. Bending on the front reverses the green tint. Loose connection, a short, or failing screen altogether?
EDIT: I looked at those screenshots while my screen is normal and I can't see the green tint, so this is really weird!
