display light spot - Acer Iconia A500

Hi
yesterday I saw a light spot (that it's visible only with white screen) in the top-right side of the screen, under the power bottom.
it's visible only at high ° of inclination, if I look my tablet directly (90°) it isn't visible
I don't know how it's possible that, has someone info about it?

It's possible that the Digitizer might not be fully contacted at that particular point in the tab. I have seen a couple of posts about this. This is a hardware/manufacture defect more than likely, or something that happened over time and usage. Considering the location near an often used spot, this is probably true.
I would suggest if you can live with it, then just ignore it.
If it really bothers you, then you can remove the back cover of the tablet, and check for loose connection fasteners around the display/digitizer areas. But really, if you have to look really hard at certain angles, in the right light and color, then I would ignore it. Not worth the trouble.

Few questions about X2

As a fresh owner I have a few questions:
1 - The lower right corner of the front panel wobbles (?), moves slightly on touch, I can press it for about 1mm (see the attached screen). It is especially annoying when pressing OK or dial off (or whatever the button is called). Is it normal?
2 - The screen has a slight green tone (hue), can anything be done with it?
3 - LCD has noticeable light leaking near the bottom side, again, is it normal? (Well, the screen does not work now anyway, gotta flash the phone.)
Thanks

(1) I have no issues with this, seams fine on mine
(2) I cannot notice any hue, maybe you have a faulty unit given the blue colour and the movement of the panel.
(3) Yes LCD light is noticible, I also get leaks through the optical pad when I have the notification LED's on
1. I got some small loose on the front pannel upper area, it's especially felt when You hold the phone in one hand and work with Your thumb pressing the screen or just put the phone to You ear. You feel then the pannel moves a bit down. Maybe thats normal or just the build quality is not so good at all.
sounds like you have a faulty one. mine is solid as a rock. the loose screen and the green hue could be related. there shouldnt be any discolouration at all and i can only see it getting worse to be honest. where did you get it? if its somewhere reputable then id take it back and ask for a decent one while its still in warranty.
i do have tiny bit of light leakage near the buttons, that does seem common.
Mine is well made too, no hardware problems.
I have a silver one, solid as a rock, light leaks are present though...

Pink hue on screen...

Am I the only one who sees a pink color on the screen if the screen is tilted at an angle? I checked a floor model at Best Buy and didn't see any coloring.
If you take the device, rotate it so the corner with the clock is facing you and then corner with the Google voice search button is facing away from you and then tilt the device so you're looking at the screen in a sort of flat manner (but it happens much before it's flat) the screen turns pinkish. It also occurs when you do it from another rotation, same angle.
It sort of kills the quality of the screen since IPS is known for good viewing angles. It's a B6O, the floor model that didn't have it is a B7O.
No problems here with pink screen. Really though if you have to flip to that angle to see it what's the big deal? It's not an angle you would normally have the TF at to use.
I'm not the kind of person to whine about small things. Like I said in the first post it happens much before the tablet is laid flat. If I'm holding the tablet in a normal position and begin to turn it left or right the side of the screen that I'm turning it to turns pink. This is not a abnormal position for the tablet to be in. If I'm not directly in front of the screen it turns pink even if it's a little bit to the left or right.

You're holding it wrong.

[Q] Viewing Angles?

Hi guys, sorry if this has been posted, tried searching and couldn't find anything.
Anyways, I want to know something about the phones screen and I would like to conduct a little test.
Could you hold your phone in front if your face and turn the phone to your right (as you would if you wanted to show someone the screen full on who was sitting on your right) and look if the screen inherits a blue tint. Repeat this but to the left and see if the screen inherits a yellow tint.
It is seriously noticable on my device and I want to know if it is just me. Thank you.
P.S. I have had my phone for around a week and the bottom 1/3rd still has a slight yellow tinting. Any idea is this fades or is this just a dud LCD?

I have the same tinting effects when I angle the phone, it's noticable but it doesnt really bother me.
This has already been confirmed...mine does it too.
+1 another one here. It is a slight tint though nothing to worry about or notice, unless you are looking for the tint.
The viewing angles on this phone aren't the greatest if that's what you're getting at :/

New Grey line on left side of my S4 screen

Hi all...
I have just notice two days ago a grey line on my screen...(left side)
Really noticeable on a grey screen (not for red/green but also present on blue, just less...). I have never noticed this before, despite of being several hours per day on my screen since several monce... No drop....
As you can see, small spots are also visibles, particulary on bottom left side (like "commons" dot on amoled screen). Its like a strip causing a little gradiant on left side (when looking very hard....)
I can see it on screenshot so it's a screen issue...
I saw a lot of thread reporting grey lines due to amoled technology, but i think my case is a little bit different...
Photos of my screen are here:

Anywone have this issue? It's not very noticeable but enought to boring me... But for the moment i can deal with it...
Thx for your feedback..

If you use your phone a lot in landscape mode, the grey line could be screen burn in from the status bar. I have read about people claiming this can happen (not necessarily in landscape mode.) It looks to be the right width to suspect this.
Of course, i think you're right! I suppose the only solution is to change the screen right? It can be considered as a screen default for warranty?

Weird burn-in issue on cm13

Hello, been visiting the boards for a long time, but I didn't register because I had nothing to contribute really. <.<
I currently have a i9505 running on cm13 6.0.1.
Last night when I wanted to reply to a text I used the right side lock screen shortcut that's set to messaging the circular motion thingy messed up the edge of my screen. (I didn't realize until later that it's not actually a hardware issue if you ask me.)
Some pictures, screenshots don't register anything:
CAN'T POST IMAGES because I'm a new user. :/
It's on imgur, with /a/Murqy extension after .com. Album of three images.
Messaging shortcut thingy on the second screen is a lock-screen burn in, as is lock screen in the middle of the first screen.
Sorry for the garbage quality screens, I don't have any other spare phone except for the ancient Sony Ericsson with me atm.
At first this obviously looks like some display issue or a burn-in. I've checked the display, it has absolutely no scratches.
I've also read about the quality issues of some S4 phones and glass+display being glued together which can lead to yellowish tint. And how display breaks easily because of bad build quality and too much pressure being put on the display itself.
Anyhow, ever since that brown/yellow thing appeared the right/left lock screen shortcut animations stopped showing. And that thing is the exact size of the lock screen shortcut animation.
Also, those three burned in lock screen buttons, phone/unlock/messaging aren't really burn ins. When I try to press any of them in the bugged state when the screen is already unlocked, the dropdown menu activates. Also when I use dropdown menu myself, those 3 buttons are instantly gone without leaving a trace. And when the dropdown menu is activated, the yellowish corner translates from the background to the menu itself. Icons on the home screen in the background aren't yellow anymore, but icons in the dropdown menu are.
So, I'm completely at loss what to do here. I don't wanna use one of those burn in removal apps to mess my phone up, I don't have a warranty because I got it used like less than a month ago and everything was working fine. And I don't wanna take it to a repair shop because they'll just tell me the display is messed up.
There's just too much coincidence here for me to believe it's a classic case of display burn in.
Why wouldn't lock screen shortcut animations show up anymore if that was the case? Even on the left side which is completely fine. And it just appeared out of nowhere when I used one of those shortcuts. As if animation is stuck in there.
Sorry for the wall of text, but wanted to explain it in detail as I couldn't find anything similar anywhere else. <.<

I'm not familiar with burn-ins, but since it's a used phone the probability of the screen being messed up is high.
If it really is a software glitch, the only option would be to flash a different rom. If it continues, flash a stock rom via Odin. If the problem still persists, then it's most probably a hardware issue.
Remember, the flashes have to be clean flashes. As clean as possible. Dirty flashes won't help, especially when trying to find the root of a problem.
I've had it for nearly a month now and I didn't have a single issue.
As I've said, it's probably not a burn in because it just appeared like that due to one animation.
And since it's also there when I boot into recovery I don't think flashing a new ROM would help.

Is this gradient (around the icon) visible to naked eye? This is really nasty Just a guesswork: this could be one of failure modes for amoled. I have 8 weird rectangles burned in over the whole screen and really don't know where they came from.
Check this: http://forum.xda-developers.com/showthread.php?t=2603039 evidently even light from outside can burn in your screen.

Yea, it's visible.
That's the far right shortcut on the dock.
But the weird thing is that it just disappears if I try to click it.
Same goes for the lock screen shortcuts as I've said already, that's why I'm not sure it's a regular case of screen burn.
And when I pull down the dropdown menu, the color of the desktop goes back to normal, but dropdown menu icons in the bottom right turn yellowish, as if the tint translated to the screen that's being used at that moment.
After I realized that I tried to mess around with color saturation and brightness.
Changing brightness had no effect, lowering it would just make that corner darker, but as I dropped down color saturation on all of the RGB components more and more it became less and less noticable.
But the buggy lock screen shortcuts still puzzle me. They remain on the desktop after I unlock the phone, but are instantly gone as soon as I click them.
If it wasn't for that, I'd be pretty sure the screen broke because of bad build quality. I read about the display having too much pressure put on it, somewhat of a design flaw.
Gonna try that burn in app, what's the worst thing that could happen to a broken display. <.<

Does it disappear if you press and hold without actually doing something? Make a screenshot and display the image fullscreen as if it was lockscreen, will it happen again? While showing the screenshot, press and hold on the icon, any change?
Does all of the gradient disappear or just the icon burn in?

If I hold it, it actually works (eg taking me to messages or phone menu as if the screen was locked). It doesn't appear on screenshot, only after I unlock the phone. That's what's puzzling me, it's not actually burned in, it looks like an issue with the display when I change screens (from locked to unlocked or switching from desktop to broswer like in that screenshot with the burned in icon, as soon as I click it it also disappears, same as shortcuts).
And gradient gradually disappears as I lower the color saturation. Disappears fully at around 30% for all RGB components. But brightness is way too low then.

I know, I just wanted you to make your phone display the same content as if it was locked - but now the image would be screenshot and not the actual lockscreen... I know this sounds really wild, but I don't see any better troubleshooting ideas here

I get your point, like I'm leaning towards display issue but not a classic one but a weird one because it has issues with switching screens.
Idk, I'm gonna roll with this for a couple more days, if it gets worse it's definitely the display.

Maybe tomorrow if I find a half-decent camera.
Actually, I made a screencast.
https://media.giphy.com/media/3oGRFj88fgqgT3vWrS/giphy.gif
As you can see, after I unlock the screen, all three shortcuts are burned in.
When I press the burned in unlock icon it just briefly opens the dropdown menu (it wasn't me opening it at that point, when I clicked the lock screen icon in the middle)
Yellow tint in the bottom can't be seen on the video.
