Xperia Z1 flicker when data is on - Xperia Z1 Q&A, Help & Troubleshooting

Hello, I bought the Xperia Z1 3 days ago and I've using it ever since, but I've noticied a bit of a flicker as if the refresh rate is too low, it becomes so apparent at gray coloured areas of the screen, but what's confusing me is that it doesn't happen all the time and that it only happens when I turn the data on and sometimes it doesn't flicker but when it flickers the data is definitely on, I've updated it to 4.4.4 in hopes thats a software issue but the problem still persist.
I don't think it's a hardware issue as it doesn't happen all the time and it's always related to data being on, any advice on how to fix this?
Help please, Thanks in advance
Update 1: I noticed that the screen only flickers when the data is GSM only (2G), But when I turn it to WCDMA only (3G) the screen doesn't flicker!

Nexus One Screen Interference from wifi/data

I didn't know how to search this so here is my topic. Lately I've noticed when the WiFi or 3g/2g is receiving or sending data my screen will show a strange flickering interference but it is only noticeable when the browser has a pure white or other light color background, and even then its hard to see. Nothing malfunctions just wondering if anyone else has the problem. BTW this happens no matter what kernel/Rom I'm using.
honestly I have never had this issue
i've never seen this but i will start looking for it now. great, all we need is another minor bug to irritate us.

[Q] Screen flickering under WiFi data transfer

Hi,
I have my sgs about 2 months and I'm very happy with it. The only problem I have is, that sometimes there are strange displayinterferences.
It looks like there are moving waves from top to down.
Does anybody have this troubles too and has a solution for it?
Or is it an hardware error? The problem is that the error isn't reproducable.
Maybe somebody can help me, please!
Thanks in advance

I think I have also noticed that once or twice. I believe it can be seen when you have the android drop down menu (notifications etc) open and you start or stop WiFi. It must be some kind of interferance with wifi hardware. Normal wifi operation does not cause it, only the startup of the WiFI which lasts one second or so.
Yeah, i think this could be true. I also see it often, when I open die Notification bar. But I also have the same interferences, when I am working in apps. Maybe also the 3G connection could be the reason? Does anybody else have this problem.
Is this a problem, which I have to life with or could this be an error of the hardware(warranty)?
http://forum.xda-developers.com/showthread.php?t=753402
I have the same problem. Never on wifi tho.
Which firmware are you using?
Hi,
my firmware is I9000AUJF1(A1 branded from Austria). I don't know if the problem in your posted thread is the same. The interferences I mean only exist one or two seconds. There are horizontal dark lines which moves from top to the bottom. After some time everything is OK again. It looks like anything interfers the display(wifi, 3g?).
The problem of warranty is, that I'm not able to show the problem, because it's not reproducable.
Screen flickering under WiFi data transfer
I noticed this problem a couple of days ago.
Whenever there is some data transfer going on over WiFi, wherever I am browsing or some service syncs up the screen starts flickering and I have what I can describe as faint scan lines crossing the screen vertically like there is some sort of interference.
These are mostly noticeable on white and light grey backgrounds.
I have gone trough 2 firmware updates currently being on stock JPK rooted.
I have searched around on google and found on some forum one guy that was saying the cause is an interference between the WiFi module and the screen refresh rate.
Has anybody encountered this problem or these symptoms ?
Is there somebody around more knowledgeable in this issues that can confirm that this is a hardware problem ?
wow! , you might have a defective phone then.
I use WiFi very often, Wireless N at aprox 87 Mbps
that should be high enough to reproduce the problem you experienced, if i had a faulty screen
the description of the scan line reminds me of interference when you are in close proximity with another LCD or CRT screen causing the distortion field
OMG, I get this too. Usually happens on boot or when I'm browsing a data heavy website or using Android market. Are our phone defective? Does anyone else have this problem? I wonder how common it is.
does the scan line comes from bottom up
or goes from top to bottom?
very slowly or fast?
if you are pluged in and charging, also are you in a 120v or 240v?

They tend to be random and I'm on battery power atm. Also they're quite fast but don't last very long. They'll start then stop then start etc ..
Hi,
just for your information. I've sent my phone to samsung on friday. Maybe they find the error. I report, if there are new information.
Yep i have the same problem. Can t find the source though....

The lines appear from top and travel the screen fast.
Imagine a TV who for a second has problem with reception.
I am on 240 V.
Also the issue is much more noticeable when not plugged in.
If I have the phone plugged in its barely noticeable.
I will try to call the service and ask about this issue. I have a strong feeling that this is a hardware issue. But Besides the screen being defective I also think about the battery. Maybe when in high load (WiFi) it's voltage varies and affects the screen.
It seems if I uncheck Power saving mode in Settings>Display and also uncheck Automatic brightness things improve a bit.

Another issue to worry about .. God starting to think about selling this phone and getting something else. Stuck in a 2 year contract though
some one already reported this on another topic
it does seems that some version of the phone are prone to WiFi interferance
we still haven't found out what causes it exactly
for example i can not replicate the issue on my phone when using WiFi
found it
http://forum.xda-developers.com/showthread.php?t=793944
Cant reproduce it.
Not that I'm unhappy with it...
If this is a hardware issue Samsung should replace my phone. I am waiting though a little bit before calling the service to make sure that it is a hardware problem.
If I find that it can easily be fixed with a software fix, it's not worth the hassle of trying to replace it.
can anyone in North America confirm this issue?
i got a huntch it might be an Europe only issue related to the high voltage of the electric interferance nearby, like lights, tv, radio, wifi, etc.

screen burn on moto g5s plus

do anyone face screen burn issue in this device i am facing this issue in indian variant xt1804 and also i m not getting update what should i do for screen burn issue should i give it to moto for replacing screen or anyone else is facing same issue i can fix that issue but i m scared it comes again and again does it get much more problematic by time
sorry for my bad english
all opinions and suggestions are appreciated
I just received this phone yesterday. I'll keep an eye out for this issue
Sent from my Moto G (5S) Plus using Tapatalk
can anyone just put their device to maximum brightness and keep the device on home screen for about 5 6 minutes and on data switching option above switch is there any network bar and battery transparent like thing and please if anyone can do this and report it would be helpful specially xt1804 users (indian varaint ) or any variant
I don't have screen burns but screen gets jaggy sometimes showing mostly green and black strip but it's in milliseconds and only when I play videos but the thing I noticed it might be screen issue cause no matter I watch video on MX player, chrome or any other media or other video it happens when video goes on for long run
It shouldn't have burn in, it's not OLED (IPS) so it'll be harder to achieve that permanent burn in like a Pixel 2...Might just be a defect
I get burn in but it's completely temporary. Every morning after not using my phone for 5-6 hours while sleeping there's no burn it at all.

Screen flickering and artifacts.

Hi All,
After updating to Oreo got this weird issue, screen flickers every, roughly 2 seconds. Wit the times it also starts showing some color artifacts, freezing some parts of the screen and eventually going to complete gray-to-black flickering only. Anyone experienced something similar?
I'm thinking it may not be Oreo upgrade related just (unfortunately) some hardware issue.
Cheers
AlzirR
I've had similar issue after updating to oreo.
Half screen displayed artifacts.
Nokia replied to me saying that there is a bug in display drivers. Probably gong to update it soon.
Had to send it back.
Replacement works fine.

The left half of my screen is covered with black/white/grey artifacts. Sometimes after resetting or going back to factory defaults the screen goes back to normal again.
Running Oreo on a 128gb Nokia 8. REally hope it is software related (driver?). So far installing the latest updates doen't fix the problem.
Switched back to my old Samsung Galaxy S6 but man I miss my 8 already.
I changed the motherboard and I got ghost touch problem then I change the lcd and everything seems fine to me
I don't think is sw problem
I have the same problem today. As i received a call, display start to flicker. As i have all imp docs in my phone as i relies on NOKIA , I am as nothing. Somehow I am able to reset to factory reset. phone start works, but I lost all my valuable datas. How can one relies on NOKIa, who was one of BEST
Bro I have a issue of red strip visible on egdes when we turn on night mode for long time with a grey background

Samsung Note 9 - Display Discoloration & Overheating

Who else are facing the same problem ?
1)Initially, when I unlock phone by pressing power button the display was changed to dim colour(mostly yellowish) and with horizontal lines displayed when the brightness is below 50%. After tried with multiple times pressing on power button the display came back to normal.
2) Next stage, it's not solved with power button. I have to keep my phone aside for some time to get back to normal display. It's been 15 to 20 min then.
3) Now, I would get normal display only in morning. Else, I need to keep my phone idle without touching for at least 4 to 5 hours. I've also changed screen power off time from 30 Sec to 10 Minutes. So that my screen wont turn off and I can keep the normal display. If I forgot to use or kept aside more than 10 min then my screen would go off and display would gone again and irritation starts with that discoloration problem..
4) If display changes to yellowish to reduce the horizontal lines problem I need to increase the brightness to 80 or 85% but this causing my phone with another problem "heating issue"
Samsung haven't responded on this issue yet, how could we bring up the issue and get the proper resolution from Samsung.
This happened after last March update installation?
What note 9 do you have?
Probably not a hardware fault if it happened after recent software update.
A number of note9 affected although samsung seems to disagree at the moment.
Hello,
I also have a problem with the display after waking up with the POWER button. There are tinted colors distorted and some stripes like dim lines and slow refreshing. Everything started after updating to Android 10. In fact, when the display lights up incorrectly, it starts to heat up from the bottom. Putting the smartphone aside for a moment or cooling down causes the display to work correctly.
Workaround? I turned on Active Display and first knock to activate it, then the display lights up correctly and then I unlock the screen and use normally. It is known that battery consumption increases. Of course mine is Exynos.
hi guys,, i remember a similar experience sometime back.. try this. if u have turn on the proximity sensor i mean the advance feature where the phone screen doesn't turn on while in pocket , switch it off and restart the phone and see if the problem still exist.

whats the firmware version u are having now and phone model?
Try wiping the cache partition in Recovery Mode. If that doesn't work then back up your device and manually reinstall the OS back onto your device.
Im having the exact problem. I flash LineageOS and it worked by max brightness then back to auto. I installed brightness widget to max brightness and back to auto everytime I turn on screen.
This issue is popular after March update. I tried everythings you mentioned above, reset, flash new firmware, even April update, wipe cached, flash cooked rom, heat screen, turn off features, disable gpu overlay, etc... Samsung Vietnam guaranteed can fix with new screen but I'm out of warranty.
I dont have any issues us unlocked snapdragon xaa model on latest android 10 version.
Can we confirmed that a screen replacement fixes the display problem or is it still a software issue

No one knows what is the exact cause here, its noticed in many devices right after this March update but few are noticed months before. But, now the problem came to many users at same time. So its been brought up by many tech blogs, websites.

I'm having the exynos version too but with ITV (Italy) firmware ...never had this problem and now I'm on April's version after March's version.
This looks a little bit like what happened to the S5 years ago when after 1 and a half/ 2 and a half year's the screan began flickering, having green spots or lines, randomly didn't go on with low luminance settings since it completely died....a lot of people said on forum's that it was the screen and a replacement solves, but when it happened to me years ago the Samsung assistance center told me that it was another component (never told me what it was) causing the issue and once they changed it , they solved the problem.
So, after my experience with the S5, don't know what to think now for what is happening to some guys even if I think that this issue might depend with something happening after marchs update because for the too many people having it after the update, coincidences are not credible.

Yes, many people were facing this problem and how many times we have contacted the Samsung they are behaving like they just hearing the issue for the first time. Just created and posted the link in Members app and 67 members joined so far. Everyone having the display problem out of nowhere. All of them on out of warranty except one or two. Still members app floating with the display problem messages.
Display issue got noticed in S20 too but they immediately released the security patch and solved it. Don't know why they were silent on Note 9.
