[Q] Blue blotches on screen?

Hi, I I tried searching for this issue but couldn't find any thread specific to my problem. In darker lighting and on dark images or video I notice some bright blotches in the left center of my screen. It's a pain watching videos with it, but does not impede use of the device. Forgive me if this is common light bleed, but I thought that was exclusive to the edge of the device. Is there any fix I can do on my own or should I try and rma?

I would personally suggest an RMA, that doesn't look right somehow...

U have heavy lightbleed on the top and bottem left side of your screen.
But those blobs in the middel should not be there.
I would suggest a RMA

I had those on my 16GB that I RMA'ed....now my 32GB that I got as an exchange is starting to do it as well.
Starting to regret giving Asus another chance. Never trusted their products before and with good reason......

Thanks guys I'm going to try and return it to Fry's and get the new samsung galaxy tab instead.

You're the third person I've seen with this issue in the past week which is an alarming trend to say the least.
Did it develop over time? Was it there in the beginning? Check your serial number on the box for the revision code (starts with B, EX: B5O, B4O, B6O), which is it?
Definitely RMA. It's unacceptable when there's tons of light bleed on the edges but when it's in the center that's just ****ed.

Looks like I'm too late to return, I'll have to RMA. The serial number is B4O, and I suddenly noticed it, though it's quite possible that it happened over time, I don't recall it being there when I got it.

I am having the same issue, though not as bad. I will try to post pics when I get time.
I just can't decide if a RMA is worth it.... sigh.
My Serial starts with B4O as well.
Edit: Is this actually light bleed or something else? It looks like the IPS screen was impacted before install.

I just sent one back for having a white blob in the middle of the screen about 4mm in diameter I assumed that was light bleed of some description there was plenty round the edges too..
The really worrying thing is the replacement that has just arrived, if I apply light pressure on back of tablet about two inches above asus logo it looks like something is pushing against the screen you get all those rings and what looks like a rainbow effect. I noticed it when docked and moving the screen back and forth the same effect occurs.. I never saw this on my other one, is this just cos the unit is thin and flexes or is it another badly put together tab?
I love this product, why cant it just work

I only notice mine at near full brightness, and with the room pitch black. They are pretty small too. I think I may just try to live with it, as it seems RMA isn't a 100% fix either. I'm afraid I'll be without it for 10-15 business days, and possibly end up with something worse!

yep mine seems to be much worse

That's ridiculous. I shouldn't be afraid of more problems after sending my unit in as a RMA. I think I am just going to hold off and reevaluate the issues in a few months. I'm just worried that the dust in my screen will continue to get worse and worse.

Can anyone speak for a device with a different serial? Also, should I wait and see if ASUS actually fixes it, or RMA as soon as possible? On a side note I thought for RMA they would send me another one and I'd ship this one back when I got the other one, does ASUS not do this?

What's your S/N prefix on the replacement?

This is how it will play out:
1. You call Asus and set up an RMA with the extremely rude customer service.
2. You pay return shipping (about $14-$20) to ship it back to them.
3. They take two weeks to wait for parts and then a week to repair and send it back to you.
4. They end up replacing the LCD and not doing a replacement for the whole unit. You get a "repair", not a "replacement".
5. If you so much as leave a single ding on the unit the service center will mark it OOW (Out of Warranty) and claim no liability for repairs because you damaged it.
At this point the light bleed is so bad you really have no choice.

So at this point my options are to RMA and most likely not get a fix, keep it and try to ignore the lightbleed, wait for better manufactoring/repair and then RMA, or sell it for $180 on Gazelle or maybe more on Ebay/Amazon and use that to buy the thrive or tab instead. I'm leaning towards the first and maybe the last, but I'd be paying about $750 on the last one (calculating new tablet price by adding old price and subtracting the difference.). Suggestions?

Just noticed this on my transformer. It's barely a month old! Gonna take it down to the service centre tomorrow. Ridiculous.

How'd this work out for ya? I was curious how the Galaxy camp was doing so been reading through the Galaxy 10.1 forums, geez I thought we had problems, lots of similar complaints over there about build quality, keyboard lag, reboots, etc and worse of all evidently alot of them have what they call Newtons Rings effect on the tab where the top glass presses against the LCD and makes water looking blotches some of them over half the screen and it changes with temperature lulz. I have seen that stuff before on anything with an Otterbox Defender case with that built in screen protector, those always do that and it's hideous I couldn't live with my tablet doing that.

I have just sent my tf101 back for the newton rings effect you describe.. Maybe galaxy tab ain't the answer either then

Need Opinion on return device.

So I just received my Tab 7.0 Plus from Amazon and it has one small dead pixel. Super small but its there. Should I return it? Its on the right bottom corner and of course only noticeable in dark colors. I'm tempted to exchange it just for that little pixel.

I would return it but ask if they have a policy on it. Some companies put a definitive number of "acceptable" dead pixels (depending on screen size) before it warrants an exchange.
The only standard I know of for sure is Apple because their "acceptable" number is zero(0), as in there should not be a single dead pixel regardless. Amazon probably would accept it though, worth a shot.

have you tried those apps that try to help fix stuck pixels? on my nexus one i thought i had a couple dead pixels but apparently were only stuck pixels. some app i used did some flashing of different colors and the stuck pixels never showed up again.

One thing I like about Amazon's exchange policy is that they'll immediately send you another tablet while you keep the other. Once you receive the new one, all you have to do is send back the defective one. They don't seem to ask questions about it. I totally bricked my tablet when I rooted it and they took it back.

cool.. Suck that Amazon won't have it on stock for 3-5 weeks per their site. I asked wifey and she said it doesnt bothered her and wouldnt even noticed it if I didn't say anything. It was for her so she'll keep it. But If i noticed amazon brings it back in stock soon, I might just exchange.

Dead Pixels are not a good thing
This ISN'T my Transformer Prime

My story with dead pixel shortly.
I bought my GT6200, same night the battery got empty and the tablet start shutting down and at black screen I saw a dead pixel. Next day I was in the market and all I sed was: "There is dead pixel". No one even wanted to see it. The guy sad: "Ooo, it`s normal for Samsung" and gave me another one brand new. I was like this because this behaviour and returning policy is not normal in my country.

[Q] Display tilt problem

I've got to the conclusion that my S6 have some screen glass 'problems'. Whenever i tilt it the colors change a little, from that yellowish white it goes to some blue accent; and also the botton of the screen is more white then the top. This is very noticeable indoor with brightness on auto, at the outside i don't really notice some of these 'problems'... I know that all of these things are specific to the amoled category but sometime it's irritating.
I've send an email to the carrier from i bought the phone and they told that the phone will be send in service; and replacement its not possible(i have bought the phone online).
My question to you, should i send the phone to the service ? I mean, it is two weeks old.. will it be the same after a screen replacement ?
I'm knox tripped also but i think this it's not gonna be a problem since it's a hardware issue.
Thanks for your time.

If you're knox tripped, then good luck. You still have warranty (in EU at least) but got to fight for it.
I got pink dots all over my front camera (getting worse and worse) and Samsung say the reason of the pink dots is cause of root, even tho there is documentation for it being a hardware issue on SG6.
So well, if Samsung can get you to pay for the repair in any way, they will.

I wouldn't bother. A repair will come back the same or worse.
Colour shift is normal but still one hundred million times better than any LCD. The white balance is AMOLED all the way and they ALL do it (on S6 and note 4).
I would learn to live with it.

Pink tint on screen?

Does anyone have a pink tint to part of the screen? I know the Galaxy s6 had a bad problem with this. I'm hoping it's been solved in this generation.
http://forum.xda-developers.com/galaxy-s6/general/getting-replacement-s6-due-to-screen-t3074865

No pink tint on my S7, but the screen is not uniform. Bottom right corner is what it's supposed to be, with white background, but the upperpart has a yellowish tint to it.
Going crazy with these AMOLED screens, because last time I tried to buy a S3, I had to cancel my purchase after 3 units. They all had the same problem and I really tought, that Samsung could produce good screens after so many years, and because this isn't that much different with S6's screen

My Verizon S7 just starting displaying this problem. Bringing it back to Best Buy ASAP today.

My flat S7 has a bad screen too : Pink / Green color shift from top to bottom...
I already had this problem with 3 different S6 so I'm really disappointed the issue is still present with the S7. Got a RMA but it may takes 3 weeks for a replacement thanks to the ****ty consumer service in my country .
Here is a shot of the problem (the 2 shots are the same I have just augmented contrast on the second one to clearly see the problem).

I'm quoting myself from another thread. Still an issue... I'm waiting for a replacement model right now and I hope the screen will be good.

Yep, I've got this issue. Pink tint at the bottom of the screen. The only negative of an otherwise faultless phone. I kind of wish it had an IPS LCD, seems these AMOLED screens are very inconsistent with colour. At the moment it's not TOO bad but I'd prefer a uniform display. Didn't have this issue with the S6.

i have to exchange my amoled phones ALWAYS a few times (ordered my 5th S7 Edge today)!
i wrote a few threads regarding this, i also sent a message to displaymate (because they test "cherry-picked" devices, and do not mention this), see here: http://forum.xda-developers.com/note-4/general/note4-amoled-screen-quality-t2906365
1st: display not good compared to second device
2nd: the device i use now. very good viewing angles and no tint, BUT: left side of display is darker then right side
3rd: display strong yellow tint
4th: display almost good, slight yellow tint. would take this, BUT: front cam takes blurry pictures compared to other devices...
5th: ordered today!
you may think i'm a hypocrite or have OCD, but it makes me mad that a 800EUR device has such flaws!!!

I absolutely agree with you guys. We are paying a significant amount of money and we expect it to be perfect.
Kudos for keep trying @TML1504. Hope you get a perfect one this time.
Are you buying this from a local store or a online seller? Because all local stores in my country will ask too much question if I approach them for replacement since it's a silly issue related to display, software, speaker, camera. Mostly likely it will end up in a pointless argument from their side and they consider the issue under warranty only. Speaking based on my earlier experiences.

Are the screen tint issues happening straight out of the box or do they develop over time?

Are you guys noticing it when the display it tilted or even in straight position?

I got a replacement unit yesterday, but had to wait almost 4 weeks for it. Didn't get a DOA replacement at the store, because the store manager didn't see the yellow tint. This new unit has slight pink tint on the top part of the screen. Gonna wait till thursday and decide if I'm gonna change this one. Probably not, because with my luck I have to change phones too many times, and the store manager doesn't want/or can't see the problem.
Maybe I'm gonna forget and get used to this screen, because it's little bit better than the first unit. Driving me crazy that Im so sensitive to this kind of things

Same issue here. Been speaking to Samsung's UK arm on Twitter and they say to take it into my local store (even though it was bought elsewhere). My worry is that I'll make the trip and be told there's nothing wrong.

galaxy s7 screen problem
same here i preordered a galaxy s7 and after 1 week of use i started noticing some color shiftiing when i'm in a dark room the auto brightnes turns the light down
and i start noticing ( especiallly in grey, grey dark and green dark cloros ) that the left side is brighter than the right side .
it's like a wave of light from the bottom left to the upper left of the screen this is really annoying when using a grey theme for example .
i compared to a galaxy note5 and s6 and they also have the same problem but in different parts of the screen.
i can't return it cuz the people in samsung want notice the problem. and they will tell me there's nathing wrong with it so i'll keep it until next year.
and by th way i had the same problem but it was pink on the right side whit my s6 last year and i changed the display twice under waranty, the third try i've got a farely good display.
maybe the next year i'll buy an iphone.

Yep, picked up and replaced by Samsung UK within five days. New unit had a perfect screen

Grey lines on display

Noticing a kind of very lite shade of greys in white screens irrespective of the brightness. No problem with any other colors. Can’t capture it in a snap. So tried my best to represent it in the image(attached). You can download the image and zoom-in and shake the image in the marked area to clearly see what I’m talking about. Anybody else having this issue? Is it huge issue as I will be working with photographs in the phone?
Just bought the device yesterday. Would be nice if someone can tell me how to convey this to the retailer without making him think that I’m crazy for a replacement. :laugh:
Unlocked model S7(flat)

I have found that all modern high density AMOLED screens have this to some extent. I bought 7 Galaxy S6s and none were perfect, with some better than others. 99% of people won't notice it. And even if you're someone who can notice it, sometimes it takes a couple weeks of owning the phone before you see it, and then once you see it, it's hard to unsee it. It's especially noticeable if you're scrolling and move your eyes up and down the screen with the content as it moves.

I saw it in the first day itself. Expected value for the price paid is not delivered means. It's cheating

Its very common on AMOLED devices unfortunately and my guess is that the vast majority of users cannot see it so lower # of units returned to samsung and they probably will blame it on QA. If a lot of consumers would start to notice it and demand for close to perfect panels then samsung will probably up their AMOLED game.

we bought 3 sgs7 phones all of them have this issue...how can such a company like Samsung do this ...like i cant see that LOL my vission on close distances is verry verry good so thats whay i saw those gray lines in a minute after buying one.i went to see my brothers gs7 after that and of course his one was the same and then after one week my father bought one white version so i thought that the 3rd one has to be a good one but NOPE it was the same story again...im very pissed so i will go to Samsung and tell them about it and will see what will they say...just to let u know guys i had similar problem on xperia z5 but instead of grey lines i had white ones and also some white spots and i send it to waranty and told them about the display issue and they have replaced the screen and now its perfect...so im goin to do that on Samsung aswell. good luck ppl

just to let u know guys i went Samsung and they replaced the screen but those gray lines are visible again so they sad that they cannot fix it and change screen everytime.... it looks like that alot of led panels are baddly constructed in the factory so i decided to return the phone.

I am on my 3rd galaxy S7. The 1st had the SD card connecting and disconnecting. The 2nd one the USB port would no longer transfer data(learned because VR stopped working) I am worried about the build quality of this phone....

I have exactly this same issue and it's driving me nuts! I cannot return my phone now, but it's very noticeable for me those grey lines when some other people I tried to show it couldn't see it...I hate AMOLED displays, I have never had a phone with an AMOLED display which was perfect, all of them always had some issue at some point. From Motorola, other Samsung, Huawei, all of them had some sort of issue with the display.[emoji35]

Replaced once, too. Mine was not a perfect line, like gray dust splattered along a line. Especially visible with grayish flat images, there were clear fluctuations on shade of "gray". Second device is almost perfect. If you look with magnifying glass , there were some pinkish littttle dusty dots on white, but it is really hard to see with naked eye. So happy with second now.

This issue is present because AMOLED screens don't use backlight. Every pixel is emitting light, and my guess is that they aren't distributing the same amount of brightness on every area of the screen.
It's noticable, but as some said to a very small amount of people, and it isn't that much of an issue if u ask me. Bigger issue is that amoled screens burn in over time. I could see my keyboard on white background on my S5 after a year and a half of use. Thank god that s7 has themes so I can change keyboard layouts.
Everything comes with a price... LCD's have their flaws, and so do AMOLED's.

Good news, its just a software bug on Android M, just reflash it to Android N and it will be fixed.

My experience.
Hi all,
I have an unlocked, rooted, Nougat ROM S7 Edge and I have been experiencing the same issue for 3 months.
The only way for me to fixed it is to flash Superman ROM, then the lines disappear. Any other ROM (Elyos, S8 ports, ...): I have the grey lines. A kernel issue?
Cheers.
P.S.: Flicker free kernel used to work with Superman ROM but if I flash it after any other ROM, my phone gets stuck in boot.
