Anyone else got this on their gtab 4 7" ? - Galaxy Tab 4 Q&A, Help & Troubleshooting

I just got a 7" tab4 today and when I got home, I noticed that when the screen is black(not turned off but displaying black) there is a bit of extra light on the bottom right corner.It's not that noticable but it's there.It doesn't bother me but anyone else got this ? Do you think I should replace it ? Problem is I already applied a screen protector so that would cost me 20$...

It's just a little light bleed. Most lcd screens have it to some degree.

Glue/adhesive under screen?

So I got my transformer Monday and its great, however there is one very minor issue. If the screen is black and you tilt the pad at an angle, you can see what looks to be some kind of smudge or adhesive on the LCD panel under the glass. Like I said, this is very minor and you really need to be looking for it to even see it. I bought the transformer from best buy. With all the other issues, ie speakers and dead pixels and what not, do you guys even think its worth taking back and trying to get a replacement?

Hmm, this post is very helpful.. lol Good thing its relevent to the thread.
I have never seen the smudge you are talking about, can you take a picture of it?
Heh, but seriously, if it were me yes I'd swap it for a new one, just knowing it's there would annoy me.
I ended up swapping it. No dead/glue spot but there is light leaking from the corners on the left side and also from about half way down the left side as well. It isn't in my main viewing area so its not a big deal, and my favorite background is white so I don't really notice it, but is QC really that bad on these that this many units have issues still to this day?

Light Bleed is a common issue with tablets. Google "ipad light bleed" and you will get some interesting posts.
Also, aren't IPS displays known for a little light bleed anyways? Something that we have to live with, I guess.
I can deal with light bleed alot easier than a dead spot on my screen. Its easy enough to fix with a white based wallpaper. And luckily my favorite wallpaper is white based.

Yellow Tint

So on low brightness the whites seem a bit yellow. Can anyone confirm this?

Its a common problem, at 0% brightness white is a tad yellow but still its much better than having blue/green or pink tint.I've tested lots of S3's in various stores all shows same phenomenon so getting your set swapped wont solve any purpose.

Well even at high brightness settings it looks a bit yellow. When I tilt the phone it looks more white and when I tilt it back you can clearly see the white is a bit yellow.

Yes its a "Bit" yellow on low brightness but on high brightness mine is pure white, its common with AMOLED they are unable to attain LCD whites.However this doesn't bother me much because I'm used to it now, keep in mind its not an tint screen is tuned bit warmer.
Ahh so it isn't just me

Well.. It even seems to be a pretty pink compared to the GS Plus. Both at full brightness.
Sent from my GT-I9100 using XDA
I think it's configured this way because blue pixels expire the quickest in amoled screens </not expert opinion>.
In either case, past phones have been able to use color controls like supercurio's app to change the tint. (And, by then you might've gotten used to it anyway.)

I just checked it against my Note and mine is pinkish. It isn't distinguishable when not doing the comparison though.

Stop comparing displays and enjoy your S3.
I didn't notice it before the comparison and I don't notice it now. Only during. It is a non issue for me

[Q] quick feedback needed on pink tint on screen

need some fast feedback on this. Last night I noted that the top left part of the screen is less bright on 0 brightness In my bed room, with careful monitoring it looks like I have pink gradient on the top part of the screen at zero brightness. Do any of you guys have this pink tint issue on top of the screen? This can be noted only in dark room with zero brightness, also with zero brightness the whole screen looks a bit pinkish but it totally vanishes once the screen brightness is increased from 0.
This issue is totally unrelated to smearing or red pixel issue afaik.
I need some opinion regarding this guys.

At 0 brightness my screen also displays a pink tint on white.
When brightness is raised the tint gets lesser
That's nice to hear, I have a chance to replace my device today, hence I'm making sure that I'm not doing something wrong. @Obagleyfreer
What about the pink on the top part of the screen? Can you reproduce it?

My device shows pink at the top left and also slightly all across the bottom.
This is only on very low brightness in a very dark room. Normal usage it's not noticeable
It will be good to know if your replacement device has it also. This is actually my second Galaxy S4. I returned my first after 2 days as there were 2 lighter stripes running horizontally across the screen on grey and white at lowest brightness!
My advice to you is to take the phone into a dark cupboard in the shop and double check everything! lol
The trouble with AMOLED, as I'm sure you're aware, is that you can replace a screen with 1 problem and get another problem on the new one.
Which is why I settled with my slight pink tint at low brightness screen lol
Good luck!
I also get very slight pink tint on black in dark room, but it looks pure black I am normal light. Should we be replacing or not?

but with screen adjuster the smearing in almost fixed, as of no way to fix red pixels issue unless an sw update is issued.
some people with smearing issue got red pixel issue after a firmware update right?
btw the purpose of replacement is served.. the pink tint issue is now no more
Will be interesting to know if you get screen smearing after updating. Keep s in the loop dude!

[Q] Display brightness issue

I'm currently on my second N3 (the first one had vertical lines in photos) and looks like this one has a bad display. When using Tapatalk with the dark theme, the bottom left corner/edge of the display is brighter than the rest. When testing with Screen Adjuster, the difference is very noticeable. The issue can be seen even with just Thumb Keyboard with WP7 theme.
Has anyone else noticed this kind of problem?
Return it and buy from another store. Seems like these guys are selling you lemons.

The two phones are from different stores, I'm still waiting for a replacement for the first one.

Check it with the stock messaging app, it should have a uniform brightness. Mine is glowing on the left edge and especially on the bottom left corner.

You may notice that the black screen when you open the settings. Not symmetric Colors.
There is a difference in the backlight. Increase in the left of the screen.
AMOLED has no backlight! the issue is due to the production process (basically: the more of the center of the wafer your particular screen has been cut out, the more uniform it will be)!

If you want to get rid of display brightness issues, just switch to Dynamic, as the 'blacks' in Settings would be even blacker, to the point where it doesn't really light up as it uses the OLED technique of showing true black.

[Q] LG G2 Matrix problem ?

Hi All!
I think I have a problem with a display on my LG G2 D802. I have noticed, that under angles I can see, what I think it is, a matrix of the display. See attached files.
It is pretty vissible, even on the photos. On the day light it is seen even when the display is on, not only with the display shut down.
Does anybody see the same thing?
I have never seen this on my previous phones.
Thanks in advance for replies!
Do you use a screen protector?
Sent from my LG-D802 using XDA Premium 4 mobile app
It's just the IPS matrix (if you're referring to the grid on the screen visible at certain angles when the screen is off).

Annoying? Yes. Normal? Yes
