rainbow screen when tilting - Google Pixel 4a Questions & Answers

Hi there,
Just received my new Pixel 4a and pretty happy. Just a question. I'm coming from a 2Xl and I just want to ne sure that the screen is normal. It has a kind of a rainbow effect when tilting the phone (specially on a white background). It doesn't matter that much, but when i'm reading some things, it can be kind of disturbing.
I don't have that kind of problems with my old phone. Is it normal? Is it something we are obliged to deal with when having a "cheap" oled screen?
Thanks for your answers.

I have the same problem here, not sure if it's normal. Nobody mentions this on the reviews.

I am using it with a tempered glass and a slight rainbow is there at extreme angles. I wouldn't imagine myself using ths phone at those angles, so ita not an issue for me.

Yes, there is a slight green/magenta rainbow effect. For me it looks like it comes from the gorilla glas they use but could be the OLED or a combination of this too.

[ASK] Touch Pro screen doesn't mend with the frame?

hi everyone,
i just got my Touch Pro, but i noticed that the flushed screen, on the right hand side, isn't mended well to the frame, where i could slightly see light from the screen coming out, especially in the room where it's dark
does anyone else experience this? it's just slightly and visible only in a dark room where there's no light except your Touch Pro. just worried someday, it may just collect all the dusts and let them in, going under the screen.
Yes, mine has that as well. I was a bit disappointed, but I'm hoping it's not a major issue, though using the case and a screen protector might help a bit.
For now, I use a piece of scotch tape (inserted thin-side into the crevices) to pull out any dust from time to time.
oh well, they should have done better on controlling, i didn't find it such issue on my diamond, well it's a different screen implementation after all, but the latter was better IMO

[Q] Light bleed fix?!

Well, the more posts I see around, the less optimistic I am about seeing Asus fix the light bleed issues with the TF. For some reason, this is the only issue that is bothering me enough to consider returning it. If it wasn't for that, I would be a 95% satisfied customer.
Anyways, instead of waiting for answers, I figured I'd look for alternative methods of fixing the light bleed. I came across this post:
http://www.avsforum.com/avs-vb/showthread.php?t=1125227
Do you think it's possible. First we need to know what exactly causes this light bleed to be able to address it. It could be simpler than we thought.
Have you guys tried this? Any other recommendations?
Well bang away and let us know what happens.....
P.S. Go JETS.
Not sure if you could do this due to gorilla glass overlay

From everything I've seen on the internet, I just think light bleed is problem of the technology, its what happens when you have a screen that is using a side lit LED screen vs a back lit LED screen. (Ipad2, Transformer, and multitude of LED Tv's). Its the drawback of having the thinnest screen that everyone is wanting.
I'm not so sure, mine didn't have bleed at all until after I'd had it a couple of days, it just appeared. I'd handled it with kids gloves. I'm wondered if the light bleed may be caused by the case distorting a bit due to internal heat and or the fact that the housing isn't particularly strong?

If you carefully put pressure on the bezel you will notice that the light bleed is changing. It seems to be a dynamic process so your observation doesn't mean you "abused" the tablet. It's just the problem with having a flexible material (plastic) as case.
That means that it must be related to some pressure on those spots where the light bleed is originating from. Perhaps there is a way to relieve it some?!

I have no idea if the following is true but I think I remember the light bleed is caused by insufficient sealing. So if you morph the case it might lift the seal more. To find the right spots to fix this is very difficult IMHO (acupressure ).
Flex your TF or press on areas of the bezel and you will affect the light bleed.
There is no way to fix without disassembling it and having right tech to reassemble in a way that is perfectly even.
What causes light bleed?
Kinda a dumb question.
You see, an LCD panel needs this thing called a 'backlight', that shines through the liquid crystal layer. It's filtered by the liquid crystals to produce different colors.
Well, sometimes this backlight can 'bleed' around the edges of the LCD because it's not sealed up properly.
The 'fix' for this on a device like a Transformer would require disassembly and reassembly to better seal the edges of the screen.
The best solution any of us will be able to get will be to RMA our units and hope the replacements are a little better built. Personally, the bleed doesn't bother me much at all, so I'm not going to bother.
Could ASUS not ad a this metal support border to the screen, to counteract some of the flexibility in the chassis? EK follows the same principal with their waterblocks (allbeit for different reasons)
Maybe ASUS could fix it by adding some felt around the glass before assembling it, let it act as a washer.
how about some ducktape ... that fixes everything.
the light bleed is def due to to much pressure on the screen

Really? Are you that obnoxious? You gave a pretty complex and technical answer to just a dumb question.

the glass on the screen sucks, and other complaints

compared to the iphone 4 i used to have, the infuse's glass sucks.
had the iphone from its release to the infuse's release in may, and the screen didn't hold fingerprints (easily wiped off) and had 0 scratches. apple's oleophobic coating works very well. my infuse doesn't get clean easily, fingerprints just smudge around and the screen looks nasty all the time. also, it's got small scratches all over it.
not saying the iphone is a better device overall, just that apple is superior to samsung in fit and finish, and material quality.
...not to mention the horrible color quality and banding you get at anything lower than 25% brightness, or the general creakiness and weird sounds the device makes (not solidly built at all)
i've had the phone for just around six months and though it's been nice in many ways (performance and camera quality are good) , the infuse has mostly put me off getting another samsung phone.
anyone else have similar experiences? any solutions for my screen woes?

Yea! I get very sweaty hands at times, half the reason why I bought a big phone. I will admit dust, smudges, and fingerprints do make the phone harder to read if I'm outdoors. But when I'm indoors the smudges and fingerprints on the screen still make it very readable. I use a microfiber cloth that is very soft to clean my phone screen off each and everyday from smudges, dust, and fingerprints. The coating over the glass is what is causing fingerprints and smudges hard to clean off.
Edit: I don't like the sound and looks of phone protectors.
I've had my Infuse since August, and a Captivate for nearly a year before that. NEVER had a scratch on either screen. Gorilla Glass is awesome. Never use a film protector. My Infuse glass is like new. I wouldn't wipe with an Apple product, and just as my 'droid does, I eat apples.
Screen on infuse is awesome! You may want to Quit using screen protectors... Mine screen still looks brands new. Picked up the infuse on launch day and never used anything for protection! There's no way you can do that with an iPhone!

I didn't even bother getting a screen cover for mine and it's still like new after using it everyday for 3 months. No scratches, and i don't really experience the banding problem that you mentioned at all. In comparision to the iphone, i don't know why you say it has worse color quality. Side by side, the OLED display kicks the iphone display out of the water in terms of color production, not so much in terms of pixel resolution, but that doesn't affect color.
i don't use a screen protector
color quality is only worse at low brightness settings, at max brightness the infuse is far better than the iphone
you guys don't get banding issues at low brightness? i asked about this before and the general consensus was that this is a flaw with SAMOLED+ displays, and that there was nothing i could do about it.
@axiomkid
that coating on the glass (not a screen protector, the coating from the factory) should be there to prevent fingerprints and oil from collecting on the display, not to make it more difficult to remove! that's the purpose it served on my iphone, at least. dunno if samsung is doing something backwards here lol

nope. considering i am at 0 brightness most of the time, and less than 10% most of the other time, I don't see any such issues.
for me, greys and blues look horrible at low brightness. it's gotten worse since i originally bought the device back in may.
it appears as weird color banding and artifacting that is in a constant pattern on the display, as in it doesn't move when i scroll something.

Have you tried supercurio's screen tuning app (requires root)? It helps out a lot with the blurry text and banding. I can't say I have anything but love for my SAMOLED+ screen myself.
I haven't really had any issue with the glass either. I have very few scratches, no big noticeable scratches at all since I've had it, and when I get finger prints on it I just pop it out of it's case and wipe it on my sleeve and it's typically fine. If I let the screen get really dirty, it might take just a drop or two of water to help clean it, but the glass on my phone is in great condition.
supercurio's app is a huge improvement over the stock settings, but mostly just for text in my experience
banding isn't much iproved
Supercurio's screen tuning app works great even on Stock Froyo 2.2. No issues with display set at 9% Brightness, I never go higher than that since it's not needed and I rather not fry my eyeballs with the screen brightness being too bright.
Edit: Had my Infuse for about 2 months now, Not a single scratch, nic, dent, Not ANYTHING! (Knock On Wood!)
My glass is scratch free and I have no problems wiping the screen off when *my hands* smudge it.
wow,
my experience has just been the opposite. The Infuse Gorilla screen is awesome, no protector, no scratches and i typically just wipe the screen on my jeans or shirt. once a week use a damp cloth on the screen only. I got the Infuse 2 weeks after release last spring.
Prior to the Infuse, I had also had the ip4, 3gs, and 3g and think the Infuse screen minics the ip4. I thought the finger print protection on the iPhone4 was garbage...didn't work on my phone.
i guess i just got a good iphone, and a crappy infuse
My phone is always in my pocket with my keys and change and i have no scratches on it. Smudges come off easy so its just u having an issue. Maybe make sure your hands are clean before u touch your screen.

+1. Its an expensive piece of tech, don't rub your grubby hands after eating some wings on it (exaggeration) and then complain on how dirty the screen is. Besides, the crappy iPhone glass is WAY more prone to cracks and such than the infuse glass.

The screen on my phone is fantastic. I've never had any issues on it. Now iphone, yes. My 3G screen scratched myself on an empty pocket.

its not an iPhone... Its a Samsung Infuse.
Why would you make a thread just to complain?
The iPhone is a great phone, however some of those claims are just ridiculous. The glass is undeniably better on the Infuse than the iPhone 4. That's just a fact. Some of the complaints are valid, like the build quality and camera. You win some you lose some.
not sure the problem my screens fine no issues, screens still looks bran new

[Q] Are these dead pixels?

Hello guys, i just noticed today this hairline tiny black strip on my display, thought it was dust but it didn't wipe off. My phone is a week old and i never really had a device with defective pixels before so i can't really tell what this is. I ran the defective pixels fix videos for 30 minutes but that didn't help. Sorry for the image quality, i don't have a decent camera to capture those tiny pixels.
I also noticed that i have light bleeding from all edges when i view the device from an angle, is that normal for the nexus 5?
Could it be that there are gaps between the glass and the display that allow dust to go beneath the glass, and this is just a dust particle under the glass?

The light bleeding is normal I've seen on all Nexus 5 i have owned, the "Dead Pixel" is a little hard to judge , but in my opinion as its not solid square(s) i think it may be dust or debris.
I had purple spots start showing up on my first one. That doesn't look too bad but it would bug me too.
Do you think that more dust could get in if that's the case? I have a local warranty and i'm leaving this country after a month, if the issue won't grow bigger than this, then i may just live with it as i don't think LG would give me a replacement unit here.
Not sure if it would be an issue for them as the phone isn't dust proof,I'm no way saying its cool as it would annoy some people. I guess best thing is contract them and see what they say mate

It looks like dust to me, but to know it for sure I recomend you to take it to a LG Center.
They may not give you a replacement unit, but at least you will know what the problem is.

[Q] Display Issue, Viewing Angle, Normal?

Hi Everyone,
I recently bought a Oneplus one and am a bit disappointed with the display. Besides having the yellow part at the bottom, when I look a little at it at an angle I see the screen tint to whitish almost blue and this effect increases as my eyes level to the surface, this is best seen by looking from the right corner of the screen with a black background. Is this normal? I only need my head to be slightly away from the screen to notice it. Also I notice light bleed from the top.
Let me know if this is just an effect of the LCD display and if its normal. I've used amoled displays before this.
Regards,
Bobbie

I don't have this issue on mine. Honestly though, why is it such an issue? The scenario you're describing would just never happen in the normal use of the phone, nobody looks at their phone on such an angle when using it.

Hi Heisenberg,
Thanks for the quick reply. I do notice it during normal use otherwise it wouldn't be a problem. The phone is on the left side of my computer now and as i'm looking at it I notice the whitish blue tint while using a black background.

Fair enough. Dunno what to say though, I have two of these and neither of them have a tint when viewed on any angles. I initially thought my screen protector might be why but that can't be the case because one of them doesn't have a protector on it.

Mine does have a screen protector on it that was already on it when I received it, could it cause some kind of tinting? I only see it from an angle not if i just look down from the top to the bottom of the phone, then it looks perfect.

It's possible. Those films that come already on the phone aren't actually screen protectors as such, well they're not meant to be used for an extended period of time anyway, they're really just to give light protection during the shipping process. I'd recommend you remove that one and get yourself a good tempered glass protector. The Nillkin 9H is exceptional and it's quite cheap too (less than $10).
