I just got a replacement droid turbo 2 today because my previous one was faulty. However I noticed that black pixels still have a backlight although this is a AMOLED display that should only illuminate the pixels necessary. Everything from the active display to just completely black pictures, I notice that all pixels have a backlight. I did not run into this problem with my original turbo or 1st turbo 2. Has anyone else had a similar problem and/or know how to resolve it. And input would be greatly appreciated. Thank you

Hello
I purchased G1 with broken display on eBay from other user, hoping I could fix it.
G1 works good, its rooted and running cyanogen rom. Digitizer works, display is readable but colors are upside down. For example in settings screen text is yellow, background is blue arrows are somewhat gold. App menu background is black text, blue, attached pictures should tell more, one is home screen and other one is flashlight app with half intensity.
I dissembled the phone, searching for any signs of damage or anything, everything seemed ok. I am not sure if I should buy new LCD screen or Flex Cable. Did anyone encountered similar problem?
Hello, I think my HD2 have screen bleeding. When i'm outdoor, I have hard time to see anything on display & there is a three white bright dots on display. Can I fix this problem or I need to replace display and digitizer ?
display is quite bad in outdoor bright sunlight so that maybe normal, white dots sound like maybe dead pixels.
Try posting some images of it if you can.
Also look at backlight setting for brightness & see if adjustment seems to work correctly as maybe have issue with LCD backlight !
Like you already are thinking, LCD is needed but some images would be good to confirm this & I would not re-use the current digitizer unless recently replaced & removed without any damage.
hello everyone
i received my snapdragon note 3 yesterday, was playing with it till i found something, its hard to explain but i will do my best.
what i noticed is that when i move something blue (like the small bars between each alphabet in contacts) to a black space (where pixels are shut off), the blue bar turns purple for like quarter of a second and then goes back to its original color.
it is really bothering me, i waited like a month to get the snapdragon version from outside my country and now this is happening.
could it be software issue? as i remember that note 1 has a display issue where black color appear grayish in homescreen, if so, what are the best stock roms that support RDLV root with out tripping knox ? last thing to note is that it is really hard for me to return it to where it came from.
any help appreciated.
edit: it apear that it is happening with the gray color or any other one that tend to be grayish at very low brightness

This is something you'll either have to get used to and learn to live with, or sell the device. It's a HARDWARE issue, not software, and it can never be "fixed" in any way. The short explanation:
What you are seeing is the latency inherent to the design of the AMOLED pixel matrix. It takes some time for the pixels to go from black (off) to any other color (on) and what you perceive as a blur or "small bars" before it does so is this latency, and when you are driving so many pixels on a full-HD display, the latency is even more apparent.
Samsung has attempted to mask this design limitation by essentially taking true black (off) away from the user, but it only works for Samsung apps and the parts of the OS that are tied to the Touchwiz UI.
update:
it appears that this problem is called smearing/ghosting, the reason it happen is that samsung made pixels combletly turn off when it is black in addition to cutting any power going to the screen.
why Samsung did this? well, to fix something called mura effect (black amoled screen can be seen as green or brown in very dark room), this caused a delay in turning on the pixels again which caused this effect (especially with gray color).
the solution is to use an app called screen adjuster (found for free in play store) and using the following setting:
red +14
green +14
blue +14
brightness 100
contrast 0
hope this help anyone who encounter this problem
cheers

as i said in the post above, i managed to solve it but adjusting screen colors (a Little bit that it does not affect the overall colors and in the same time keep black pixels on)
by the way, are all note 3 owners facing this issue like what happened to most s4 users or just me?

Just so you know that all you've done to "solve" the problem is shift the colors up to remove black. It's not worth the loss of a true black (off) pixel state, IMO, but to each his own. All Note 3/S4 owners have this issue. Some don't notice it until it's pointed out to them, but it's a hardware/design issue common to every single unit without exception.
I broke my screen a few days ago and had it taken in to be replaced. A few hours after receiving it I noticed the LED was blinking, but in strange colors different than those I set in Light Flow. The normally white notification is now cyan, yellow is now green, purple is blue. Red however doesn't display at all, so it seems that the red portion of the RGB scale is not functioning. Does anybody know what during the screen repair process might be causing this to happen? I'm almost certain its not software related as prior to having it repaired the LED was working correctly. Thanks!
There's a kind of filter for the LED on the display, not all replacement parts come with it and it's pretty easy to overlook.

There does seem to be a blue hue around the notification light area when held in the light... So could it be that this filter was mistakenly left on the old screen, instead of transferred to the new part? Or is it something attached to the screen that can't be moved from one part to the other?
It wound up being a damaged LED light
Hi folks,
I dropped my G5+ (XT1687) the other day and cracked the screen. I ordered a SRJTEK replacement from Amazon, but after installation the new screen can't display colors properly. Instead of RGB it's more like "weak purple, weak green, gray" as shown in this picture from my housemate's phone. The picture shows the colors faithfully as on this replacement LCD. I've tried a factory reset and some display calibration apps, as well as the system UI tuner and the developer color-blindness options. Any app with color sliders shows the weird red, green and gray instead of normal RGB.
Has anyone seen anything like this before? I'm assuming it's defective, but not sure if I should ask for a replacement or a refund.

Try connect the wire again of screen, if it doesn't work the replace it with new one.
Colors should be accurate if you installed it correctly. If you bent the digitizer in any way it might do that. Give it another try by gently pulling out the digitizer and putting it back in (use tweezers, NOT your hand to prevent short out). If that doesn't fix it then issue a return to the company for your money back.
