Screen changing shade issue

This is NOT about banding, horizontal lines, or blurry edges.
This is about the shade of white changing when looking at a white screen. (Market, white webpage, reddit, xda forums, etc).
Here is a video link showing the issue:
http://www.youtube.com/watch?v=G-mVWkBK41I
Symptoms:
When viewing white screen and scrolling up/down, notice a small, subtle change in the shade of the predominant color. (From a grey white to a lighter grey white, etc)
Steps to reproduce:
1. Turn brightness low for best results (automatic settings off)
2. Use phone in dark place for best results
3. Go to a page with lots of white/light colors for the background, (xda forums is a good example)
4. Just go about your business and read comments as you're scrolling down.
5. Notice a small change in shade/tint/hue every 5-20 seconds.
Notes:
1. I've tried to turn brightness very high to see if this countered the problem: Fail
2. I've tried turning on automatic brightness: Fail
3. I've tried mixed settings with automatic brightness, auto adjust screen power: Fail
4. I've tried to play with the phone in a well lit setting: Fail
---All of the tested conditions above, I was still able to see the change of shade
Questions:
1. Is this a hardware or software problem?
2. I've read that some people who have experienced this exchanged their unit. Did it fix the problem?
3. I heard reports of running the dead pixel app for 20 minutes might fix this issue. Any thoughts?
4. For those who never noticed the problem, could you try the steps above and see if it happens?
The reason that this is a problem is that it strains the eye. In ocular terms, adaptation is the eye's ability to adjust to various levels of dark and light. So when this change of shade occurs my eyes have to readjust to that shade, but it occurs so often that my eye is agitated from having to adjust over and over.
I have a few days left to send this unit back overseas (/sigh) so I'm trying to get as much info as I can here before I take the next step.
Thanks.

Update
Just upgraded to XXKL7.
I heard some users report that this issue is less visible and/or gone due to update.
I will test this more thoroughly tonight and report back.
Prior to the update I emailed the vendor, with screen shots. Still waiting for a response to see what their position is.
Here are the screen shots if interested
Image 2.1 - opened market
Image 2.2 - scrolled down a little, notice red tint
Image 2.3 - scrolled down more, notice tint went back to normal
Any other users that have this shade problem, please reply here if the newest update has fixed or alleviated your issues^^.

I reported it straight away. The hue change has gone with the update. It is not there any more.

Thanks for the response. I'm excited to hear the news.
Just to be double sure, have you tried with screen filter(app) on?
During my testing, using the screen filter showed the change of shades more convincingly than not.
Could I request of you to try it?
On another note, drawing on the s memo seems like the shades are changing a little bit. I'll keep that in mind for testing.

Confirmed gone on kl7 here too!

another update
Issue is definitely not gone after the update for me.
It has become more subtle than before but still apparent and annoying on the eyes.
Still waiting for response from vendor. Will update again then.

I have the same problem, in fact I've already commented on your youtube video before seeing this post. I have a video of my own up. The problem I have is my item is all packaged up ready for RMA. I don't know if I should try KL7 or not.

Strange. Mine and a few others its definitely gone. No more changes at all

I'm gonna try KL7 on mine now. I have obvious tinting which I doubt it will fix. I'll report back the moment it's done.

Out of curiosity where did you buy your phones? Just about to flash KL7 now and I'll report back. Mine was bought from Expansys, shipped from France.

Okay guys. I updated to KL7. Still massive changes in hue in the screen. I'll be sending the phone back on the 3rd so when I receive a replacement I'll let the OP know whether it helped.

I had the same issue, but in my case just turning off the automatic brightness fixed it.

Good to see im not the only one with problems. I got mine from expansys korean site shipped from hong kong. I heard they have horrible customer service. Sent an email about 5 days ago and no response.

You could try calling them. I'm fairly sure my phone came with a Korean ROM on it. Mine goes back on the third. Are you in Korea yourself?

Upgrading to KL7 made the issue go away for me as well.

same
Its happened once only to me, the screen changed to deep red, i restarted phone and its never come back.
Just to add to it, with brightness set to minimum and automatic disabled its not really any signs of hue change at all, im on rom kka and the only thing i do notice on sites that dont have white pages, like xdas creamy colour, is a bit of flickering when i scroll down.
I dont think its a hardware issue, if the problem can go away after flashing diff roms then it must be software, saying that, i was running Darkynote when it happened.

Problem is there are two of us here that have flashed a lot of ROMs, including KL7, and also tried everything everyone has suggested but we're still seeing the problems. It might be a software problem for some but so far it's looking like hardware problems for us.

I have a very similar issue. Change of hue (red, sometimes greenish) every 5-20 sec on white/grey background.
Auto brithness and auto screen adjustement doesn't change anything.
More visible on lower brightness setting but still there on highest.
Running KKA firmware until KL7 is proposed OTA here in france.
Crossing fingers that it's software... I would just hate to ship it back for servicing.

I'll be calling them today. Yes I'm currently in Korea. Expanysys Korea has their own warranty provider in Korea supposedly, with a free 3 month warranty extendable to 1 year for a price.
I'm really contemplating if I should root and try throwing on some custom roms to see if this issue is fixed. But I'm pretty noobish with all this.
Cheers and happy new year everyone!

Update:
Since expansys hasn't sent me a reply via email yet I FINALLY got a hold of expansys by phone.
Supposedly they claimed that Samsung told them that they will not fix this problem even though it's a known issue (I can't even trust that expansys even contacted samsung). But after Expansys looking at my screenshots they offered me an exchange. I'm going to get a full refund instead.
So I'll be returning the note tomorrow. After some thought, I'm going back to my S2. The Note is a beautiful phone, but I don't think it fits my life style.
Thank you everyone in the XDA note forums. I wish you the best with your note. I'm glad I was able to be a part of it.
Happy New Year
PS. Never ordering from expansys again.

Happy New Year to you too.
My phone should reach Expansys in France today. I really hope they replace it without me having to provide screenshots, the only thing I have is a video showing it very subtly changing colours. They did ask for screenshots but I told them it was almost impossible to capture it. I don't know if I should ask for a refund or replacement.

I hope all goes well for you. I'm shipping mine off tomorrow. International returns are harder than I thought. Although I'm getting a refund I can't help but miss it already lol. Maybe in the near future I'll pick it up again... ics maybe? Hehe.
I'm extremely curious if CM9 has an answer to this issue =]. Any volunteers?

New HTC One A few questions

Hi all,
I bought the HTC One yesterday, I got a good deal cut price of £210 I'm in the UK (London). I wanted something better looking, this phone certainly fits the bill. I posted on the suggest device thread before, most recommended the HTC One a week ago.
Today, I'm reading some threads in the HTC One section and it looks scary the amount of problems all kinds people are experiencing.
What is the root of all these problems? Is it to do with custom ROMs? I'm a simple user, I've never used anything but default/STOCK what the phone comes with.
If I don't update to 4.4.2 will it be safe to use?
Please advise, asap, thanks.
I'm referring to posts like cracking sounds with the speaker, loud speaker turning on by itself, purple tint on camera.

Purple tint is an issue which I've experienced, so have many of my classmates who own this phone. Ironically, my phone just came frm the Service Centre 2day after the purple tint issue.
Loudspeaker has never automatically turned on for me. Cracking sounds occur if the bass is exceptionally high. Turning off the Beats Audio from the Settings solves that problem. These 2 issues haven't affected as many people, and aren't really as big a deal as the purple tint issue.
Many problems occur when people are not well informed about what they're doing and make unnecessary modifications of their device. A very common issue is when they completely convert their device into a Google Edition, which I don't really understand why. Conversion to a Google Edition has screwed up many phones. If u want the Google Edition, u can simply flash a Google Edition ROM, which is identical to the actual phone and a BILLION TIMES EASIER than fully converting the phone.
If ur attempting something which u feel u aren't sure off, ideally u should create a thread asking for guidance before u start anything.

Thank you for your response. I'm not one to flash any ROM to it, you mentioned Google Edition. Is it ok to use it as it is?

I will check the purple tint on my phone camera. And adjust other things like dre beats for bass ect..

Look, the issue happens when u flash a Google Edition RUU on a non-GE One (Please read a little more about RUUs if ur not sure). Installing a Google Edition ROM is no issue whatsoever. But KitKat Google Edition ROMs require S-OFF.

Not really necessary. I've been using this handset since 5 months now. I've used a variety of custom ROMs as well as stock. Never experienced anything like this. (I'm talking abt the speaker issue, not camera)
FYI: If ur using the built in speakers to play music/video, turning on Beats Audio will reduce the volume but increase the bass. Turning them off will increase volume but reduce bass. That's my experience. Turning on Beats Audio, the speakers were softer than the 5S. Turning them off, it was louder
If ur using earphones/headphones, keep Beats Audio on. Considerable improvement in bass and volume
Also, purple camera has no software fix. The phone will have to be sent to HTC for repair. Took 1 week for mine to be reapired in Dubai under local warranty.
Again, another FYI, Sense-based ROMs have a FAAR superior camera than the GE ROMs. So, if ur a camera freak, don't go 2 GE-based ROMs. Also, Beats audio doesn't work on GE ROMs

You know when you open up the Camera for HTC One, it goes pink/purple for maybe 1-2 seconds like it's trying to find it's colour level then back to normal, is this the same with everyones HTC?

If its just for the first 2 seconds, not an issue. But the easiest way to test the purple cam issue is to cover the lens completely with ur hand or place it on a flat surface, with the lens touching the surface. Open the camera, look at the phone, if its the colour of the surface, then its ok. Even a small shade of any other colour will soon increase as time passes. So IMO, get it rectified now itself if u see such a problem

[Q] is this the purple problem that every one is having?

Hi there, i am just having a problem with my HTC M7, here is a video link: http://youtu.be/H5dwRawbFGs

This is not the usual Purple Camera Tint (The one that requires HTC Service Repair) This is a bug with the camera app from HTC. I believe it has something to do with there attempt to incorporate the HTC Eye Experience M8 users enjoy. It only happens at Full HD though drop your camera resolution to 1080x720 and it will work fine. :good:

Htc m7 camera focusing problems.

Hi, got my m7 for two two years now. A few months ago the camera seems to have some problems in focusing. Very often, half of the picture seems blur. I'm made sure the lens is clean. Anyone got the same problem?

By half of the picture I mean the left/right half of each picture is blurred. (Not half of all pictures are blurred)

Do you have the camera app set to bokeh?

Exactly the same thing on my stock phone. Rooted one doesn't have any issues

I was running rooted HTC M7 stock rom.... seems that it still have the issue....
But last night I just wiped out all the stock rom and decided to try google play edition. Seems like the problem is gone now.
I wonder why that is...

My camera is not focusing (auto/manual)

Hi there, my camera is having a real trouble right now.
I take my phone from the box and get the update from 4.0.2 to 4.0.3.
I did it.
Then I used like my daily phone but... the camera didn't Focus, manual or auto focus, just can't focus.
I did a wipe... Still the same problem.
I did a re-install of the 4.0.3 ROM. Still have problems.
What can I do?
Thanks.
Sorry about my english. I'm from Argentina.

If you've already wiped and re-flashed OOS, then it's likely a hardware issue.
I would contact OnePlus's warranty service prior to opening up the phone and trying to fix it yourself.

That's something that I don't want to read.
God... What a luck.
Thanks mate =/

I've got the same problem. I wiped not the sdcard data on the phone (storage/emulated/0) but everything else I wiped with TWRP as I updated to the latest OOS 5.0.3: Problem still exists, nothing solved. The phone is running fine, but the camera doesn't autofocus, every picture is blurry.
Has someone information for me, on what to expect, when I contact the OnePlus support with this problem? Or has anyone tried to repair it by himself/herself?

I had same issue around 6 months back. Its a hardware issue so don't waste your time flashing different roms like i did. Then i went to OnePlus Exclusive Store and they checked my phone and they told me that, they will fix it for FREE (even if your phone is out of warrenty) its a well known issue for 3 & 3T which OnePlus noticed a year back, as many users started facing this. If you are facing same issue then just go to the service center and get it fixed (it wont take more than an hour)
Tip: There is a third party company called Regenersis, which is authorised service center for OnePlus and many other brands, you can get it fixed here as well.
Cheers!

Same problem for me, sent to repair under warranty.
If you shake the phone the focus point will change? this is what happens to me, for a couple of months I was shaking the phone every time that I was taking a picture, sometimes focus was in the right place and I could take the picture

Yes, slight tapping of the phone in the palm of my hand sometimes made the phone focus for one time...
Thank you guys for your helpful answers! So I will try to contact the support. I'm in Germany and do hope to get the same good service as you did.

Hi folks, I asked OnePlus for a repair and they handled this quite well: My phone was back after eight days, now my camera is focusing again.
But now I'm questioning myself (and you, too )...:
A) What was the reason for this defect in the first place... Is there anything I can do to avoid it happening again?
B) I used different versions of the modded Google camera app in the past, but now I'm hesitating to install it again: could anything of this app might have damaged the focus of the camera module? Maybe the app tried to focus the camera out of its working range...?

A) Probably just a random hardware failure. It happens. Not much you can do about it. It's a mechanical component (the few left on phones these days) and can fail on day one, or not fail for years. Don't drop the phone too much, is probably the best you can do! lol
B) I doubt it was the fault of the Google camera app. I've been using the Google camera mod for a long time, with no issues.

I used a couple different builds, but haven't messed with it for a very long time. I put 5.1.018Arnova8G2-V1.3 on there a long time ago (over a year) and haven't updated it since.
EDIT: I have no better explanation for my lack of updating the Google Cam mod, other than I just fell out of the loop. Your question made me realize how far that mod has come during that time! I just installed the recent version 6.1.021 by Arnova8G2 and giving it a try.
