screen flickers with lines of . . . . . . randomly. - Xperia Z2 Q&A, Help & Troubleshooting

anyone else seen their phones just start showing lines of dots across the screen randomly, particularly under high brightness? nothing funky is turned on in developer's settings so I doubt it's software.
I'm using autobrightness, it bothers me a little. hardware problem ythink? should I take it to Sony?

You're seeing the touch sensors that are built in to the screen. I've seen them on every capacitive LCD phone I've had at times, but they are definitely more noticeable on the Z2. Exchanging it won't help, sorry.

well if it's nothing to worry about, it's all good.

Seen the exact same thing on mine. Even when it's not that bright you can clearly see the digitizer (is that right?). it's that visible you can see it's made up of columns of tiny rectangles. It's worse on a dark background or when the screen is off. And those dots appear more when direct sunlight hits the screen. Luckily it's not just me either then, thought I'd got a duff phone!

Should have seen the z1 digitizer, crazy amount of zigzag lines all over the place.

same thing w/ z ultra

Z2 screen flicker with vertical lines
I think I have the same problem with my new xperia z2 phone.
It happens several times per day (more than 10 times). The screen shows vertical lines, across the screen. I can see the pixels in the line. Also the colors change. All this for less than a second and then everything return to normal.
I wondering if this is a hardware or software problem, and if it can be fixed or no.
Thanks

Same story on my Z (6603), been an issue since day 1, under sunlight its annoying but not much u can do nor nothing to stress about

[Q] Strong green/blue-ish tint on screen when tilting phone

Hi
I have a problem that i can't find any existing threads on.
I just received my SGS2 and noticed right away when i turned it on that it had very poor viewing angles regarding color accuracy.
If i tilt it just a little back/forward or right/left, it shows a strong green/blue-ish tint on the screen.
My girlfriend also bought a SGS2 a week ago and her phone does not do this when i tilt it.
Is this normal behavior the first few days or is my screen broken?
I will make a video tonight that shows the problem.

Neither can i on my girlfriends SGS2. I will test this on my friends phone when i get home and if his phone is ok, then i'll return mine and buy a new one.
I've had 3 now and it is definitely present on all three. It's just the way the glass is as far as I can tell.

It is NOT normal! I have tested mine against two other SGS2 now, both are less that 4 weeks old and none of them has this problem.
I think what you other guys are referring to is the blueish white that all the screens have. This is not what i'm talking about. My phone shows a really strong blue tint when you tilt it just a little in any direction. It is so strong that it is even clearly visible and disturbing in photos shown on the screen, making it impossible to sit several people and watch photos on the phone.
I cannot show any video or images of this problem as i have already sent it back.

I only see the blue tint when the phone is tilted. It can be quite strong, but as I said in my last comment, I've seen this in all models I have tested so far.
Would like to see one that hasn't got this.

Don't know what you lot are on about, but when I tilt my screen, even to an insane angle and view it almost till I am looking at the side of the phone, the colour is the same as when i'm looking at it dead on.
I think the viewing angle is amazing, and the colours and brightness are just as good viewed at an angle as straight on.. so I'm confused.
You guys must be proper straining to find things wrong with this phone.

Yes there is.. My girlfriends and my friends phone does not do this. I will take som photos to document this.
I have a feeling the problem lies with the glass screen or the coating.
I switch the screen off and tilt it, I get a bright daylight reflection on the screen, but I look at the glass and not the reflection. I then notice that the glass has got a blue hue to it.
Actually if I tilt it in other directions I can see pink colouration too lol.
Have others noticed this?
I better stop obsessing now or it will start to annoy me

I haven't tested this with the phone off. But i do know that the problem i describe has nothing to do with being obsessive. The first thing both my girlfriend and friend noticed was the strong blue tint which is completely non-existent on their devices.
I aswell notice the blue tinting when i tilt it abit, its easily noticable, but its nothing terrible, its just there.
would be interested in more parties opinions, seems as though only a select few so far dont have it, or cant notice it for some reason =)
I have used two SGS2's from the first batch and one from the second batch. They all have the blue tint when tilted.

Yes we need more data.
Maybe we should also define how much tilt we're talking about.
On my device only a few degrees, less than 7 degrees produced a strong blue-ish tint wich was easily observable and annoying to the point that you couldn't really sit several people beside each other and watch photos on it. My old SGS1 did not have this problem either at all.
Here's some vids of SGS2 devices which do NOT have this issue as reference:
http://www.youtube.com/watch?v=PK7M_RNQM7k
http://www.youtube.com/watch?v=oOxAh4I2jrk
http://www.youtube.com/watch?v=Fvr_P0euqWc
The last video link is really good. It shows the screen from a lot of angles where none of them produces any blue tint. Look at 6:35 where he titlts it upwards and down again on the table. No tint. If i laid my phone on the table and filmed if from the same angle as he did, my screen would show a strong blue tint.

Lucky you, i have a "dead pixel", green one.
And a yellowspot in the rightbottom corner, but that'll fade over time. (i hope)
I'm glad that the screen has a very high resolution, it's really hard to even notice the dead pixel.
I have noticed a yellowish tinge at the bottom of the display. Only really notice it when there is a white background. Is it likely that the display is somehow faulty??

I have the exact same, a yellowish spot in the bottom right corner.
I hoped it was the same problem as the iphone or SGS2.
They say the yellowspot is from the glue that they use to stick the screenlayers together, but it needs time to vaporise and should go away over time.
But I have my phone now almost a week and i still get the spot back now and then.

Sounds like bull**** to me.
I had contact with T-Mobile today, about the dead pixel and yellowspot.
The guy told me he's going to get information for me, and see if they can replace it. he'll send me an email later.
Same hear.
Barely visible yellowish (only on whites) at the bottom part of the screen.
It varies depending on the view angle.
Perfect screen here

Ah you are the guy from the T-Mobile forum (Hiraj) with 5 dead pixels.
Anyway they told me it's in stock again next week (Monday 19th)
Just noticed that my screen keeps flickering, this is more noticeable on white backgrounds, is this normal as in the auto brightness or should I be worried?

Hi guys just wanna update you regarding screen issues.
I've spoken with people on the forum of my country, other 2 guys with Xperia S and both of them got that really barely visible yellow tint on the bottom part of the screen (also, one of these guys has 2 Xperia S -him and his brother- and both of them have that tint).
Really difficult to explain it on forums (nothing compared to the GS2 yellow tint) because it's really hard to see and only visible on white/clear colors uniform backgrounds, but according to what I'm seeing it's a common issue, not a problem of a single faulty unit.
Got a blue/whiteisch pixel to the top right of my screen
They said i need to have more then 3 to get a new phone :/`
Can i fix this ?

I have the problem too. I called technical team dept from where i bought the phone, and they asked me to do a screen test over the phone. I tap the screen it shows all white, tap again red, green etc etc. He asked me if i could see a yellowish tinge running across the bottom of the display when these colours appeared on the display which i couldn't to be honest. I took it back to the shop, and i dont know if it has to do with the bright lighting within the store, but it didn't show up hardly at all, barely noticeable. It seems less noticeable in a well lit environment, or outside as opposed to when i am at home where it i notice it more. It is midly annoying, but this shouldn't be the case.
Can anyone throw any light as to what this could be??
Thanks

I believe that yellowish tint has something to do with warmth from the screen or the battery or the screen staying on for a longer time or something or something.
because when I'm using it alot, playing games, browsing, whatsapp etc etc. for like an hour. It gets more visible.
And then it's from "barely noticeable" to "hard to miss"
I can clearly see it on Grey (notification slide down) or Blue (startscreen DrawSomething) or White.

Same here. Interesting what you say. I would still like to know where the consumer stands on this issue, and if Sony themselves would recogonise if this is a somehow a fault with the display. My Arc had no such problems.
Hi guys,
I'm new here, but I was reading the threads on the S from the start.
Reading through the screen problems I was thinking about the following:
The Xperia S's screen is glued- as I know -, like for example the iPhone4/4s'. Some i4 users noticed this yellowish tint as well, and they've came to a conclusion it was because of the glue what was used to put the screens together and it disappeared after about 1,5-2 weeks.
This could explain the reaction to temperature differences too.

Strange dots

I just bought a s3 and noticed that in the dark if I use an app with black background or a wallpaper there come Some strange dots on the screen, is that normal and could someone please check about they also have it on their s3

Yeah its something to do with amoled displays. My galaxy nexus has the same type of splotches. From the research I've done they are pretty common. I've seen some pretty bad ones. Mine isn't that bad I have 3 towards the lower middle part of the screen. It looks like this
-_- lol. I've seen others much worse. You can also notice them slightly when the screen dims if you know where to look. It is really annoying but from what I can tell its pretty common on amoled screens. You can Google amoled black spots to see just how widespread it is.
Sent from my Nexus 7 using Tapatalk 2
Ok thanks I just got so nervous, I was thinking it was something more worse. But Should I go to the phone shop and remind them about the spots so they could fix it or will they just say that's a common problem we can't do anything about it
It's nothing that can be repared since it's a manufacturing inconsistency but not a defect per se.
Usually they are only visible in total darkness with lowest brightness settings on black backgrounds which is not that much of an annoyance
since you usually don't stare for hours on black screens. (Well at least I don't)
It's sometimes annoying, yes, but that's the downside of having low-power high-resolution displays without Ghosting problems.

What hardware issues are you experiencing?

There seems to be a number of people raising certain hardware issue problems. I don't know about you, however I don't seem to have any issues at all here.
Current Issues
Light Bleed
Back Cover Flex
Warped Back
No issues here!
Vote in the poll!
Would be nice to know which possible batch you got yours from.
Did you order it on launch day or have you ordered it since it's come back into stock?
Which country have you ordered it from?
Have you had to RMA ones before?
I have no issues at all. There is a minor amount of light bleed around the bottom edge (landscape with camera at top)but this is no issue as it only affects the nav bar, and is totally invisible when set to lowest brightness setting where I tend to use the tablet . I love this thing.
If I turn the brightness up full, I have the weeniest bit of light bleed on the bottom right corner but you have to look hard to see it.
Everything else is fine
Possible Touchscreen/Multi-Touch issue?
Still awaiting for others to leave some feedback Only takes about a minute or two to test
Some of these are not a hardware issue but a chassis issue. Hardware is the components inside the tablet.
I ordered on the 13th and no issues to report.

Minor technicality.
Minor light bleed, non factor. Extremely pleased with this tab!
Minor light bleed in lower right like everyone else, which I wouldn't have noticed if not for reading the forums!
My LED is not working, our art last I can't make it work. Doesn't really bother me as in my previous tablet (a BlackBerry playbook) I turned out off anyway.

Nothing at all there could possibly be light bleed, but I have not dine a test, I am just using it and in terms if uses, there is nothing noticeable

So far as I'm concerned, hardware is anything physical, so to me the chassis falls under this. Hardware is physical components, software is well, software.
Part of the 2nd batch (restocked 11/20).
Only minor light bleed.
Alright I ordered another one due to some light bleed that is visible on almost all automatic brightness levels. I sure hope I don't get one that's worse. charging cable I got doesn't work either so that also pushed me to RMA it.
Sometimes when holding the Nexus 10 with one hand on either side, I frightening notice the side speakers slightly detach. I only noticed this three times before I promptly adjusted the way I hold it till I get a case with sufficient protection.

I haven't seen anyone else mention this anywhere, but the backlight makes a really annoying high-pitched whine whenever it's turned on, and the pitch/tone changes with brightness. From what I've read it could be a choke coil squealing but I didn't think something like this would have them large enough to make noise.

I maxed out my brightness and I couldn't hear a thing, however I did notice that my plasma makes a high pitched whine.
Multi touch all good here when using the app that was posted; tried several different touches to be sure.
Light bleed in the bottom right, pretty minor though. Everything else is solid & working though.
As for the back strip flexing, The clips that keep it secured are tiny, so it doesn't surprise me that that is an issue for some... makes me wonder how things will go once the covers that swap out the back strip are released...

I get this issue sometimes on my Galaxy Nexus when 3rd party camera apps or apps that use the light are in use. The camera on my n10 works okay at least.
I guess I got extremely lucky. Ordered the minute it first become available (Tuesday, delivered Friday) and zero issues.
No reboots, freezes, laggieness, light bleed, back flex, dust, etc..... nothing, everything has been great.
Not usually this lucky....so I am extremely pleased

Lines of dots on screen in sunlight? Normal?

As per title, at certain angles in sunlight I see a matrix of dots on screen, is this normal, ie its just the multitouch matrix?
Is it common on Z2?
Got my Z2 yesterday, refurb phone via contract. It looks new so hope its normal
Yes it's normal.

It only come time to time if u think about it, you cant compare 1 display with another xD
So as I am walking with my phone, sun behind me I get lines of bright dots going up and down the screen. So annoying!!!
yup, I was wondering about that as I've had a g2 and m7 before, but never seen this.
the screen seems fine however
It is in fact normal. It is for the capacitive touch screen. I had galaxy note and Omnia HD and they did not have something like this, but I know that HTC HD2 had it.
It's just digitizer (touch device). On some phones it's just more visible than on the others. You just have to get used to it.
its typical on slimmer xperias
had it on my xperia s and also both of my Z2s
