Hello,
When I checked my phone today, I noticed that on left and right side of the screen, backlight seems to be different than on the rest. This causes screen to have different colour on the borders, like a little bit brighter. Is this a common problem? Anybody else had this issue? Any way to fix this, or should I replace the whole panel?
Mine has screen bleed as well. And every P8 that i saw had an amount of light bleed. So the chance to get a new screen with same screen bleed is high..
Mine has a little in the bottom left corner, unnoticable though unless I install the Backlight Bleed Test app & run it.
I was going to ask you to post a screenshot to see how much BLB there is on yours (would've posted mine too), but it doesn't show up in screenshots.

Hi,
I wonder if anyone else has noticed this in the blackstone; I can see a grid of dots all over the screen when it's turned on. Ok, you have to look closely, but it's a bit annoying. I can see the dots better when I have a white or green background. For example, going to Start -> Programs I see the dots in the space between the icons.
I know the dots are from the 'resistive' layer, the dots are the sensors of the touchscreen... but they become visible and appear as small green dots perfectly aligned. I don't see them all the time, only when I have a white background or looking with a certain angle.
Should I be concerned? Could it be a problem with my screen?
Thanks!
Sounds a bit strange to me, the only time I can see the dots/grid is in bright sunlight. Then they look like small pin points in plastic.
i've never noticed that on mine...
That is normal, those are touch sensors for the screen. They allow the screen to recognise a touch.

Agree, but I had other PDAs before and never seen the dots when the screen is turned on. I don't care about the dots being visible when I'm under a bright light; my point is that I can see the dots when the screen is turned on, no matter under what kind of light. When I have a white backround, it looks like there's dust on the screen. If I look closely, I can see the dots in green colour, as a result of the reflectied light from the screen. I know they are the touch sensors, but it seems no one else can see them--
Any idea?
Thanks!
it is indeed normal especially under bright sunlight. However if you insist that you can see them when you switvh your device on, no matter the external light conditions, there might be something wrong with the screen. Have you seen other HD phones recently? Do you see the same dots there when they're switched on?

I haven't had the chance to see another HD; I've looked at a Diamond and Cruise, the dots are NOT there. I've tried to take a picture, but seems impossible to see the points in a picture (at least for the N95's camera).
I found an old tread talking about old PDAs that had the same issue, maybe they explain the issue better: http://forum.brighthand.com/showthread.php?t=207321
I'm not sure if I should send the HD to the service. Anyone knows how the 'worlwide warranty' works? I sent an email using htc.com site, but they don't respond.
Thanks!
Any advice on this matter...?
I don't know about colored dots, but every pocket pc I've ever owned had the dot grid visible in sunlight, it is normal, they should be clear dots though.
Anyone else seeing this?
I could have swore that on my first Nexus device (RMAed due to bad speaker), I could turn the brightness all the way down and use the tablet on the lowest setting.
On my new Nexus (no issues so far), if I turn the brightness dial all the way down, the backlight totally shuts off, causing the screen to be impossible to be seen.
I'm not RMAing this one because it's perfect otherwise, it's just very weird behavior
I got the brightness on mine all the way down & the screen isn't off.

Did you find a solution?
I have the same problem. If I turn down to minimum brightness (10% or less) my screen goes black. The only way I can see what's on the screen is if I shine a light, and then I can barely make out what the screen says. I assume this is an easy software fix. Also, if auto-brightness is on and I'm in a dark environment the screen will occasionally dip to the lowest setting and turn off.
I'm on my second device also. My first one had bad screen lift, flickering and occasionally screen glitches with black lines flickering through the screen. This one had no noticeable screen lift out of the box, but I'm reserving my judgement, as the device I just returned was fine for the first few hours and then got worse as I used it more.
I have both devices side by side, since Google mailed me the new one first. Comparing the two, I notice the old one's screen is slightly brighter, maybe about 10% or so, but definitely noticeable. Also my new one has a little bit of bleeding on the left side; not terrible as some pictures I've seen, but definitely there.
Update: The screen flickering returned, so I just requested a second replacement. This is actually ridiculous.
I'm seeing some backlight issues with certain shades of grey on my Nexus 4. It happens in certain places in the settings menu (near the bottom where it blends into grey) and even TWRP's grey background when backing up a rom. Franco's gamma settings help a lot, but the problem is still noticeable at higher brightness. Does anyone else have the same problem or am i being too picky? My iPod touch 4g had a horrendous problem like this where a certain shade of grey would show all these dark blotches on the screen. I figured it was due to the LCD/backlight.
Seeing this on P.A, TWRP and Stock rom.

I have the same thing but I'm just now noticing it.
Also, this may be related, whenever I flash PA and go back into twrp recovery, it takes unusually longer to boot into recovery and then I see these yellowish streaks/distortion going throughout the screen in recovery and it appears to carry over into the ROM when I system reboot.
It's happened several times, but it appears to be only when I flash PA and it goes away when I flash another ROM+kernel. I'm going to see if I can reproduce it and take a picture of it next time it happens. But after the obvious streaks went away, I noticed those gray lines, but if you look closely, there's horizontal lines too making a grid, though the vertical lines are more apparent
I feel your pain.

I also have this problem and many others. I have read many threads but no one really has the answer. I tried different Kernels and it helps but its still there.
I dont think we are being to picky, its just that we like things to be as perfect as possible, but there is no such thing.

I have had this issue from my first nexus 4, which I had issued an RMA request about this problem. My second n4 was fine and this is definitely a defect of the LCD screen.
I've spoken to a few people and checked their Nexus 4's and sure enough, they've all got it too. I think i was being too picky. It really isn't noticable unless i'm in a dark room and the brightness is high and i'm focusing on the screen. Day to day usage, i almost forget about it. It also helps that it only shows up on a certain grey colour.
Its just an effect mate, Ive seen it on everyones screenshot when they are showing there settings menu or something.
Hey guys. Its been a while now i'm using this phone. I gotta admit i give a hard time on the phone's battery (charging cycle that is, i dnt let it fully charge and all). But I can't avoid that.
Anyways. I have this issue:
When a GRAY background is displayed on the phone, (like on a white webpage, when the keyboard is opened) i notice these VERTICAL BANDINGS/GRADIENTS on the screen
They appear on the left and the right sides (1 cm or so from the end of the display).
I also notice the horizontal banding/gradient half a centimeter below the status bar but its REALLLLYYY subtle.
My prediction?
Remember i said i give my battery a hard time? Well to be its the battery pushing the display from the back (probably swelled the poor guy lol) and giving this.
Why do i think this?
Well because
The banding lies EXACTLY where the left and right edges of the battery might probably be
IMPORTANT ASWELL: When i put a pressure on the display, the glass PUSHES the display (and creates those lovely watery ripples) ON THE SAME EDGES WHERE THE BANDING EXISTS.
Extra info: It might be a backlit problem, since its not present at any brightness level on any colour. Red blue green orange pink black purple, even gray(the banding is where the backlit dims)
So yeah thanks for reading it im sure u'll do something abt this.
I cant seem to take it in any camera these defect (i have no DSLR lulz). :3
Buy a new battery and change it before it explodes.
I suspected that my tab 4 7.0 had some backlight bleeding and I just confirmed it using the "Backlight Bleed Test" app from the Play Store.
For those who want to test their own units, simply download and run that app. It will display a black background and also boost the brightness level to 100%. If you do this in a dark room then you may see the white backlight of your tablet shining through some of the edges or corners of your unit. If you do see this, then your tablet has backlight bleed.
When I testedTab 4 7.0, I found some bleeding on the bottom left corner. (I tried taking a picture of it but couldn't get the lighting right). In my case the backlight bleed is not too severe, but it bothers me to know that it's there in the first place. I'm wondering if all our units have this issue, or if some are better than others...
So...does your Tab 4 7.0 have any backlight bleed? If so, how bad is it?
Problem caused by samsung book cover!
I found out the problem caused by the samsung book cover. After I took out the tablet from the case the discoloration disappeared.
So now the question is, if is it a normal if you push a bit the bottom of the tablet, there is a severve discoloration (it' s easy to see on black background and higher brightness).Anybody else got this with tab 4 7.0? I don't now if is it a individual problem or not...
