[Q] Screen Calibration? - Nexus 7 Q&A, Help & Troubleshooting

Hi,
Been a happy owner of a Nexus 7 basically since the UK launch. In fact, three in the family and we're very lucky to have only needed to have one RMA'd and replaced by Google Play - which was really a tremendous hassle thanks to poor communication.
Woke up this morning noticing my Nexus has a very yellow screen. I don't know if it's always been there, but now I've noticed it it's really bugging me. Obviously I can get the device replaced, but after dealing with one already and seeing how frustrating that was I'd much rather see if the good people at XDA have any ideas.
Is there anything I can do to minimise the yellowing or perhaps re-calibrate the screen like GNex can be calibrated with Trinity Kernel?
Thanks in advance.

As of yet, no the IPS LCD display has proved to be a lot less calibration friendly like the amoled of the Gnex. Your only choice right now is to get it replaced again. Sorry bud.

Is nexus 7 quality that bad?

I've ordered one and I'm looking around here and.. what happens with this tablet? 90% of them have an important screen / battery / software problem?
I am REALLY scared of what I am receiving after reading this section...
Don't be, the number of people on XDA are but a small percentage of those that purchase the tablet.
I bought mine very early on, my friend bought his just recently from a completely different retailer and he has no issues.
If you read enough and look hard enough, you may convince yourself something is wrong with your tablet when there may not be.
So get your device, enjoy using it, and is there something really wrong with it if when using it, everything is working as it should?
nope, i LOVE my N7! i use it almost everyday...more so than my acer iconia 10". the N7 is fast, light, and screen is awesome. the ONLY thing i dont like is the non-standard charging "mechanism" that it uses. i hate not being able to just grab a normal micro usb cord and charger and just charging it. other than that...no complaints.
Quality is great.
Go for it!
I've had mine since day one and no problems at all. Not only that, but I've installed it in the dash of my car and it's held up great.
No its no bad. There are defective devices out there. But the quality is not bad f you get a working one. That sorta contradicts its self but you know what i mean.

When you have 1% of devices that could potentially be lemons... coupled with the fact a substantial amount of that 1% are XDA members... it's easy for a device to look bad when in the grand scheme of things, it's not. Don't get me wrong, I'm not exactly a non-frustrated user. My screen magically cracked today somewhere between me holding it at the kitchen counter vs walking to my car, yet I never dropped it. That doesn't deter me away from buying another one since after all, mine was from the first gen batch, which if an issue is going to exist... it'll be there.
if you picky about minor issue, i think you should wait till at least October to be sure the problem is fixed. My has a minor screen lifted and there is a little static noise when turn the screen on/off. Other than that, it a good tablet. Yeah go for it.
Screen lift is ridiculously common, but that's the only really popular issue. Fortunately, there are flush screens out there, and it's not guaranteed to be a serious problem down the road even if you do get one that's a little loose on the left side.
Although there are fewer reports of lift in C8 units, the underlying cause has not been addressed. There was a big thread about this earlier today.
http://forum.xda-developers.com/showthread.php?t=1856203
I had three units with screen lift and was unwilling to tolerate it, so now I'm waiting to repurchase until they get this cleared up. If you read through the first two pages of that thread you'll find that I asked the first person who claimed to have a flush C8 unit for photo verification, and that photo revealed screen lift. That was disappointing. I was hoping these newer ones with updated packaging were mostly fixed.
Most people who claim to have flush screens haven't actually checked, but that says something about how minor it usually is. Since you ordered from the Play store, you won't have to deal with ASUS if the worst case scenario happens (a cracked screen), and a hair of separation shouldn't prevent you from enjoying an otherwise great device, so long as you're confident in the warranty.
It really is a great tablet. I wish I'd kept my second unit from the Play store, the one with the least separation, because I really enjoyed having it.

Well, keep in mind that when people who are not XDA regulars have a problem they hit up Google and XDA links are generally on the top of the list for ANY Android device, so they come here to ask and/or complain about it. Then you have XDA regulars who tend to be techie types who are VERY picky about having perfection in their toys. So things the average Joe wouldn't even know is a problem can come across like its the end of the world. Finally, as many point out, you only see the problems because people don't generally come here to post "everything's fine" unless they are being snarky (like a thread I posted a while back) or just that rare person who does that sort of thing...usually as a counter balance to all the negative posts.

It's like if you visit a new country and the first thing you do is walk into a hospital... "what's wrong with this country? Everyone here is sick."
This forum is where the few people who have problems gather to discuss them, and they are a very small percentage of Nexus 7 owners. It's just that people for whom the device is working fine don't post every day and talk about their experience, while people having problems do.
Okay, thank you everyone for your replies!
It's a shame but I think what you say is true: even if this is a hi-grade tecnology forum, only the people with problems talk and talk about them, while the people without problems only reply them maybe some times and never talks about that anymore.
Anyway, I kinda hate when you guys say "Mine is ok! only the left side is a bit loose", "Its great! only the screen fails after 2h of use", "Its amazing, yet the screen cracks everytime time I touch it on this sire.."
250~$ is not enough to expect a FULL QUALITY DEVICE? I owned an iPad and a Galaxy Tab and I had never had to expect or to suffer a minor problem, and you're talking about really important screen problems (a curved / loosing side / cracking side / etc. screen has A LOT of more % of cracking, or getting dead pixels, or having another problems).
I honestly don't understand that mentallity. We are not talking about a 5$ device (and even there we could have a discussion), ¡¡its more than 250 dollars!!
I think that if this problems happen is because people accepts it like that.

90% of people in threads whining about issues have a problem. Not anywhere close to 90% of the tablets have an issue.
How many other people are going to read a thread about defects other than the ones with defects?
I got my N7.
C80.. flawless.. perfect.
Nothing more to add. You guys scared me hard for what was I getting.. and at the end, a perfect one .
People seldom post when things are working as they should. However when things go wrong....

im one of the unlucky ones.
i have blown speaker problem.
its such an unlucky issue.
problem with this is, its not easily detectable.
it was working fine. been using it for exactly 28 days and suddenly the speaker start making cracking sound when volume >40%.
its like a time bom and may happen again even if i get a replacement unit from google.

Does your Nexus 4 have a yellow tint ?

Should i return it ? everything else seems to work perfect, the yellowness annoys me a little but at the same time i dont think its that bad but my screen is more yellow than the one at the t-mobile store. I wanted to know what xda thinks.
Does anyone else have the same problem ? did you keep your nexus or return ?
I have read some other threads but i havent seen anyone state whether they decided to keep their nexus despite the yellowness.
p.s that a galaxy s2 next to the nexus
I remember others saying they had the same issue and someone explained that the yellow tint is caused by glue within the display and another component, IIRC.
How long have you had the phone, since it's supposed to go away after a while.

Ive had the phone for almost 4 days
the tint is probably normal, mine was like that as well. thats what people have called a 'natural display' on xda while the entire techblogosphere has bashed google for it. the good news is you can calibrate it. i have made my panel shine, i love it dearly. if you are rooted give it a crack.

Exchanging the Nexus 7 Twice?

Hey all,
I bought the Nexus 7 from Best Buy on release day. The first one I got had banding issues (so I thought) but it turns out where I was seeing it in the settings is common and has to do with the background used from what I found out after I exchanged it. The one I got now has bad backlight bleed and the screen seems blurry. Not sure what's up with that.
My question is, will Best Buy care if I go exchange the device again? I'd rather not be stuck with an actual defective one. Thanks!

I'm about to return mine and wait until they get more in stock, the screen on my Nexus 7 32GB is sometimes not recognizing my touches , sometimes have to press really hard on the screen just for it to recognize, and even then it isn't 100% accurate.
Something is off with the touch sensitivity tuning. I remember reading that 4.3 brought increased sensitivity to the N4, maybe the N7 is starting out extra sensitive. I've noticed it most with the default keyboard. It sometimes double types a single character. What's happening is that it recognizes my finger before I actually hit the glass, and then again when I hit it. But this should be fixable with an update.
I wish android would allow touch sensitivity user customization, something like on Nokia's Lumia WP8 phones.

I exchanged mine today for this exact issue and the new one has the same problem. Wonder if this can be fixed with an update?

I'm unsure about the touchscreen issues. That typically results from bad connections or somewhere. Have you tried Yet Another multi touch App?
It has 2 functions, one tests inputs the other is like a paint. I recommend trying to color the entire screen. This will tell you if you have any dead spots.
If your touchscreen isn't working well I highly recommend you swap it out. What good is a tablet if the problem gets worse?

I'm having the exact same problem with the keyboard... while typing, i would get rapid taps and some letters would show up 3 or 4 times. just wondering if this is a hardware issue or software issue?
If its a software issue, i can wait it out... but if its hardware.. i'll go and exchange it for a new one.

RMA Due To Tint/Hue Shifting Display

According to what I have read online, this seems to be a normal behavior for AMOLED screens. But coming from a NEXUS 5 with LCD screen, the tint shifting with changing angles is really jarring at times. I've asked for a replacement and it is coming next week. Has anyone gotten a replacement recently and still seeing this issue with their screen? Perhaps the latest batch has solved this issue or at least made it better? My current 6p has a manufacturing date of 10/29. If the replacement refurbished phone is even worse, can I tell Google to take it back instead of sending the phone I have now and start another RMA? Thanks in advance for your input.
Do you have a screen protector installed? It would cause this issue also in Android N you can adjust the screen RGB to satisfy to your likings. I bet the phone you get will be the same you just are not used to amoled and need to adjust it to resemble LCD.

I do have a plastic screen protector on the screen. I dont know how Android N will solve the tint shifting from blueish to pinkish when moving the phone slightly in any direction. I'm hoping the replacement phone will solve this issue or at least make it less noticeable. My brother's Note 4 isn't as extreme as my 6p when it comes to the tint shifting issue.

I'm willing to bet it's the screen protector causing that issue that's what they do. Try pulling it off and check then. I use a glass screen protector it does this slightly I guess but it's because I put a piece of glass over my screen. It's an amazing phone once you adjust RGB to your liking I'm sure you'll be happy and higher end screen protector's may limit this issue almost obsolete but you'll always get slight reflection issues.
I've raised an RMA request today as the top two thirds of my screen have a pink hue and the bottom third doesn't, and also seems noticeably brighter.
I noticed this issue straight away before I was aware of the numerous threads on the internet discussing it.
I have had many phones with amoled screens before and have never experienced this.
I love the phone though and if my RMA phone is worse, I'll send it back and keep this one. When I asked the Google guy about this, he just said to email him and let him know I was doing it and he would instruct what to do so they knew which phone to expect back.
My current phone is also an October 2015 handset.

Are you sure because there are numerous threads online regarding this issue with or without any sort of screen protector. But I will peel off the plastic screen protector and compare it side by side with the replacement once it's arrived.

Thanks for the info. Are you getting a brand new replacement phone or a refurbished one? Funny, how the rep told me that I must send back my current phone once I'd received the replacement because that is how the return/refund system is set up which doesn't make sense. I mean why would I want to return a phone that is better than a replacement phone? I wonder if anyone here has gotten a latest batch with a recent built date and still have this issue with his screen?

The guy I spoke to was brilliant. I explained the issue and I could tell it wasn't the first time he'd heard it.
He offered a possible explanation that there could be glue which hadn't cured fully due to it being a new device. I then said I would hope there want still wet glue on a phone that was build in October 2015! Lol
I asked what would happen if I should get a replacement and God forbid it is worse and he said to just drop him an email and he would arrange for me to send the newer device back. Anything seemed possible and nothing was an issue.
Slightly off topic but I'm a firm believer that 100% perfection doesn't exist and to be honest this slight screen issue isn't a deal breaker for me as I do really like the phone. I've had a OnePlus 2 and a Nexus 5x in the last two months and both were nowhere near on par with the 6P.

I agree with you on the 6p. I really like it as well. Let's hope we both will get a replacement that is even better than the one we have right now! I'll keep you updated once I received the replacement. BTW, are they sending you a brand new one or a refurbished? I've read that refurbished are often better than new ones because they have been tested even more and often look like a new phone.
I've no idea mate to be honest? I may even cancel the RMA or just refuse the new one. I'm either getting used to the hue or it is sorting itself out the more I use the phone (if that is even possible?!)
My speakers on the phone are great and I have no other issues. I'd hate to get another phone that wasn't as good as the one I have!
How would you tell if a unit was a refurbished...?

The refurbished units come in plain carbon boxes while the new ones come in retailed packaging. Also, on your RMA order confirmation, it would say if the unit is refurbished or not. I'm curious and hopeful that my replacement will be an even better unit so for that reason I will accept the delivery. You can always send it back if you dont like it at no cost to you.

Hi mate...did you get your replacement phone yet? I got mine today. It has a manufacturing date of 10/25 which is a few days before my current phone. The screen is brighter and the hue is more of a blueish white. It is definitely "cooler" than my current device which has a yellowish tint to it. The replacement phone shows white background better and more realistic. Most importantly, the shifting tint is less noticeable when I move the phone. Unfortunately, the speakers seem not as loud as my current phone. But I will keep the replacement and will be sending the current phone back to Google. I hope you got a good replacement device as I did!
I cancelled my RMA in the end and stuck with the original device. The pink hue has seemingly rapidly dissipated the more I've used the phone and had the screen on. I'm not sure if this is possible but I have read about people advising to give the screen a week or two of use to "settle"?
I can't really see what I was originally seeing, and that is when deliberately trying to reproduce the effect using a screen testing app, as opposed to me getting used to the effect in general use and not noticing it.

Right/Left Backlight luminosity difference

It's been a little more than 2 weeks that i've got my OnePlus 5 and i just noticed something today.
Does any of you guys have noticed any difference between the right and left Backlight ? The right one seems less brighter than the left one for me.
I'm usually not the type of guys who's constantly searching any little defect, not at all. It's a really small detail (why I didn't saw it till now ?) but it's still not normal for a brand new phone.
Maybe I'm the only one, just curious about that.
Since I'm the type of guys who want a perfect product I'm also considering returning the product for repairing or maybe replacement depending on their solution. But first, will it be a real reason to them to demand a repairing ?
Thanks for reading all this :good:
