Purple spot on screen? - Nexus 7 (2013) Q&A

I just realized that my Nexus 7 has a small but noticeable purple spot on the screen, much more appearant on a black background. It wasn't there last time I used it, I plugged it in to charge it than came to use it hours later to see a purple spot.
I play a lot of Order & Chaos online, could the spot be from prolonged finger use? If I need to return it I'll have to relock the bootloader and flash to stock right?
Thanks,
Branden

I have had this issue for a while, I assumed it was something I did which broke it.

Mine has several spots on the screen. I got it at Best Buy think I should return it?

If it's still returnable yes, my new one has zero screen spotting. I assume it's an issue with some of them but not all..

I'm going to be returning it as soon as I can, also my device has grown another spot but this one is 3x bigger than the first two.

[Q] Can you fix a stuck pixel on AMOLED screen?

Just noticed on my phone earlier when i unlocked it that i hat a red dot near the bottom. Ran a pixel test i found on the market and it shows up on any background and my brightness setting doesn't affect it. Is there any way i can fix this?
Sent from my SGH-T989 using xda premium
Press hard on the screen where the stuck pixel is so the screen distorts in that area and hold for 10 or so seconds. Thats how ive done it for my lcd monitors and its worked.

That wouldn't work anyways cause the screen it under a hard glass cover. Also its not a true lcd screen its an oled screen

Maybe an app could be developed that uses the device gpu/cpu to mimic the effects of Pixel Tuneup?
I can't link because i'm new, but it's pixeltuneup[dot]com.
Just a thought. If this turns out to be a widespread issue, a simple app might be something people would pay a buck or two for. From what I understand, PT just puts out a calibrated video signal that is good at fixing pixel issues.
Ill have to give that a look and maybe contact the developer. Its not that bad of a problem but i always find myself staring at it lol
Sent from my SGH-T989 using xda premium
So does anyone else have a possible idea? I've looked all over Google recently and can't find much about fixing oled screens.
Sent from my SGH-T989 using xda premium
I supposed you've tried the screen calibrators that flash a whole bunch of colors. Thats would really be my only advice. If it doesn't work out a warranty replacement would be my last resort

Yea I've tried a few if those already and left each one run for about an hour. As for a replacement i wouldn't be able to do since i just got this one after my last one broke. Also I've have this phone for a little over one month or so :/

So why can't you get a replacement ? The phone is to be free of defects for a year, even if you already replaced it. Stuck pixels are a manufacturing defect which is covered under the warranty. If you got it in store, go back to the store. If you got it from 611 or online call the 1800 number and tell them.
Ah ok i see what you mean now. My next issue would be to find a stock 2.3.6 Rom

Issues with T-Mobile galaxy s3 quality control.

So... I bought my galaxy s3 from tmobile customer service. With a full upgrade I've only paid $ 179 of 16gb.
I've wanted the white one but they were sold out in 16. So I've went ahead and placed a exchange of the 32gb.
The first (white 32gb) had many dust stuck under the sceen... and interfere with the camera as well... so I've called to get me a same but different one that isn't defective this time. (New in box course) now the new one has huge gap on the metal bezel area... I could fit like 5 business card.
So I called again and placed another one...
This time I've told them to put a notation on my account so that the manufacture date is most recent... (both of my defective white phones were made in 7/4/12)
Where as my blue one is perfect...besides the dark pixels.
I really think Samsung's quality control isn't as what they claim to advertise as... I understand that no phones are perfect... but at least do a better job at hiding... lol
So in my opinion I could be getting a bad batch or just unlucky... I will keep you guys updated with my next replacement in white.
Please tell us your experience with similar problems.

No he's not, he's paying for a new product so it shouldn't have any defects or problems. What's the point of a 720p screen if it has dust underneath. My 2 yr old g2 doesn't have any dust whatsoever so why should this.

No ****. How close do you have to have the phone to your face to notice "Dark pixels?"
I wasn't aware that these screen panels could have dust considering the digitizer and screen are fused together. Hmm... :sly:

Mine already has cracks in the bezel, only issue so far. Much better than the Galaxy Nexus screen issues or the first batch of One X ones.

What???? The water indicators have little red X's on them, which smear when they contact water or high moisture. What would white out do?
Edit: and for future reference, is there a place to purchase these stickers? I've read a few other products that had their water indicators tripped for no apparent reason (MacBooks... but I don't own one!)
Edit 2: there are a bunch of housings on eBay that come with the water indicators. Perhaps you could try those if you don't mind dis/re-assembling. BTW, are there any other warranty indicators on this phone besides the water stickers?

almost all AMOLED panels have burn-in issue. its a big issue here in Korea.
There definetively are som issues with the screen. After making my GN 'fullscreen' I noticed the black area where the softkeys used to be is having a more bluish hue. I believe this is to the rest of the screen aging differently because of the screentype AMOLED (super). Taking this into account it wouldnt surprise me if the screen is getting burnins etc

All this hassle is probably not worth it for me... I am out of contract and trying to figure out which new phone to buy. The note 2 or the nexus 4. I am planning on using my old nexus as a dedicated music player and GPS for my car though.

The only burn in I have is from my nav bar, and statues bar, can't do much about those!
I have status bar burn in as well. Hard to see unless the screen is fully black.

[Q] What to look for during purchase

Hey guys. I am about to get one soon. Prolly next week after my OtterBox gets here. What should I look for on the device in terms of deformalities?
I read that some people were getting crappy devices, what should I look for to prevent that? That way if the device I get in store has any flaws to it, i can complain right away instead of waiting till i get home and such.
Thanks all!

Read that too. Was hoping more could elaborate on that. Obviously the scratching on home button was just poor handling. But about the pink tint, pink lines, that's not a hardware defect on all devices right? Just on some of them? How can i reproduce this effect in store?
Try going to a white background. Like the google home page and look in the corners for pink blobs

You can dial *#0*# and check for dead pixels, speakers, sensors, etc, using Samsung diagnostics.
So I finally got one... been two days and I absolutely love this thing. No issues what so ever!

[Q] How many dead pixels do/did you have?

How many dead pixels do you have? Did you return it or live with it?
I have a single dead pixel which isn't that noticible, I feel it unlikely that I will get a perfect display if I return it. I think it's likely that most displays have at least 1 dead pixel, but perhaps this poll can answer that.
Edit: So 2 months later, i've replaced the Nexus 5 times, and all have had dead pixels. I wish I had kept the first one.
I'm surprised there are so many with zero dead pixels. Mine is completely unnoticeable unless I look for it at less than 6 inches from the screen. In fact I can't find it right now. At this PPI the pixels are so tiny.
3, returned.. 0 now that I know of, better stay that way :laugh:

1 dead pixel that took me two days to find. Not noticeable unless it is on full brightness on a completely black screen in a dark room, so never.

Some good statistics here. I think I will take a chance for a perfect display and return this to Staples.
None that I know of. No bleed either.
Sent from my Nexus 7 using xda premium
Had 3. None after replacement.
I have one about 4cm in from the top left hand 2cm down from the top on the upper left hand side that is visible except on red. So this basically means unless the screen is black or red you see the pixel every time, clear as day.
It is really driving me nuts so has anyone had any experience with returning devices with Google over a single dead pixel out of the box?
Zero. I have two in the house and both are flawless.

The one I got today has one dead pixel. It is very hard to find. I don't think I'm going to replace it though because the screen has very minimal backlight bleed. That and I also got a 32 gb one with a2 year damage warranty for under $300, so I can't complain
