LIght Bleed - Galaxy Tab 4 Q&A, Help & Troubleshooting

I got a samsung 4 tab 8 as a part of a promo from comcast (well really I am paying for it in the form of a two year contract).
However, it has a decent amount of light bleed on the lower left side. About the size of a half a quarter. I noticed it when I was in my room with the lights off so it is dim, not dark and the display was only 50% brightness. I was watching a movie and it shows up on the black bar. Being pretty anal this really bugs me.
But is it worth trying to get a warranty repair for? If I had bought this from the store it would be going back, but warranty repair is a different animal.
What do you guys think?

Can you post a picture or a link to a picture of what it looks like? Thanks

What you're asking is pretty much a matter of your own opinion but I can tell you this is not an isolated thing as mine (that came from a major retailer ) and Im sure many others have this problem, so theres a chance youll just get the same thing again unless maybe you're really lucky and they manage to hand pick you one that dont, which may or may not be possible if all the displays from the manufacturer are like this. I can only tell on mine when the screen is all black, but yes its a bit irritating to get this with the Samsung name...

SO this is what I am dealing with. It is viewable from 30% and up in a poorly to dim lit environment. At 50% it is viewable with standard room lighting. It goes invisible if the lighting is good.

[Q] Tab with Yellow patches - has it succumb to the white iPhone issue?

The Tab is the first gadget I have meticulously looked after buying it a screen protector, leather case etc. What a surprise it was when I took it the case and found some minor yellow faint marks... Ignoring them thinking it was the light I put it back in the case...
Fast Forward 1 month
The yellow patches have increased and are now an unsightly brown!!
It really does look like Samsung have been hit by the same issue the original white iPhone did.
The below picture has had the main marks highlighted in red circles. The other marks are the poor quality camera of the *ahem* white iPhone I own...

What do others think? I have tried using my glasses cloth and cannot remove any marks. It's not got wet and it certainly hasn't been overcharged...
Maybe contact Samsung for a warranty replacement? I'd be miffed if my device turned brown over time.
Just off phone with them. EXTREMELY quick to say it is nothing to worry about but their technicians would like the device back for repair as soon as possible.
Was a weird call actually, normally you just get the whole 'please send your device to here and we'll fix it if needs be'. This time I got:
'Mr James, I need to call you back after I have checked something..'
Then on the call back
'it is nothing to worry about, your handset will be absolutely fine but we would like it back as soon as possible for repair. Again it is nothing to be concerned about.'
Sounds rather suspect to me.
Lol, sounds like they think it's going to burst into flames and cause bodily harm resulting in very expensive litgation. Enjoy your new tab when you get it

Problems with the screen

I have bought a SGS II and I like it a lot but I have some screen problems (and it is not related to the yellow/blue tint on the left side). My problem is that compared to the screen of SGS I, my screen is much worse, because there is a kind of "layer" (only noticeable with low bright and you have to pay a bit of attention)like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
that makes that when the brightness is low (on the device) the screen should be like this:
but instead of that I see something like this:
. It's a kind of layer that is showed every time, so I see that noise and I think that something is wrong with my device, or do you have this problem too?
Sorry, but I can't post URLs, so open them.
Like some sort of static image noise or dithering is going on, thats absolutely not normal.. What you can do is maybe go back to the store and have it check/compared with another unit.
Defective screen? Take back to shop!
looks like a (bad) screen protector foil is applied. if that's how your screen looks like without anything applied to it, return the device to the shop...

That's what I will do, I hope my next SGS II doesn't have this problem, anyway, I have to wait at least one month to receive a new one .

[Q] One-sided color shift when looking at the screen at an angle

Have you noticed such thing on your G2 device: when looking at the screen from the RIGHT side, at an angle, there's a color shift, especially when looking at an uniform color background (red, blue). For example - when you look at the red pattern it becomes yellowish at the very high angle (almost flat), BUT this thing doesn't happen when you look at the screen from the opposite direction (left). I have a 16 GB version.
I have attached some pictures and would be glad if you could check it and confirm whether it's present on your device (display/dead pixel test software is helpful here to display one color on the whole screen - like https://play.google.com/store/apps/details?id=com.gombosdev.displaytester). And also - which model you have - 16 or 32 GB?

This is also present on my device, but i really doesn't pay much attention to it. In real day-to-day use i don't see it. Many reviews stated that there is a color change on G2, so it is an issue for most of people on G2, just some people see it, some people don't.
If you wear polarized sunglasses it's actually impossible to see the screen when in landscape, this and lack of wireless charging are the only two things I can fault on this device and honestly the former is pretty minor imo.
Thanks for your answers, so unless anyone says he doesn't have this issue I think it's just specific to the LCD panel used in this phone.
I have a blue shift to the right and yellow shift or the left. Quirky panel.

Image Retention on new S5?

Just picked up a new white S5 on Friday. Few days later, I am noticing a burned in bar on the lower half of the screen. I am not sure what to make of this? Could this just be an issue with AMOLED panels? It's not very noticeable unless you look for it, but it is definitely there. Would love some opinions on this.

Burn-in (uneven wear to be more accurate) will still happen in any AMOLED device. the technology has improved so it should not appear until quite some time down the road, at least it's supposed to have improved.
Any app that might have kept an static image for a long time there?

Well before venturing ideas, I'd like to get a good idea of what you are seeing. I'm sure that it is glaringly obvious to you since you know it's there now.. but your photos are not close ups or high res.. and you didn't circle the area or describe it in detail. Can you point it out or describe it better?
It might be exactly as the poster above suggests or I can think of three or four other possible causes depending on what the artifact looks like.

stain in bottom of the screen

Hi,
I recently noticed a mark on the screen. It's only visible with light colours (especially white, with black the mark is not visible at all).

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

I did not find any similar case on the forum or the internet.
It looks like when AMOLED display are burned (like in JerryRigEverything videos).
But, it's LCD panel here...
From this video https://youtu.be/zuq2uPAEmeM?t=211 , the mark seems to be at the same level than this "copper bottom circle" :
View attachment 4838875
Any idea ?
I've got a very similar 'stain' that is most noticable on a white background but never looked in to why it is so would be interested to find out what it is too! Not that it bothers me much and in fact apart from that it's an A grade phone as no scratches etc but as it had the stain it was reduced to C grade price so I only paid £90 for it which was a bargain!
I think the stain is glue and the spot on screen is caused by pressure. Hotspits can also cause such effects.
There were flat tvs, where the heat of the two SoCs on the mainboard (the second one was necessary for motion compensation, in single core days) would cause two squares appear on screen after the tv had warmed up.
I've just noticed a very similar stain in the same position in my LG G6. Lucky enough the two years warranty ends in two weeks haha, so it's already at the store and I hope they get it fixed soon.
