Strange lines / waves (NOT scratches) on the display - Xperia Z5 Compact Q&A, Help & Troubleshooting

Merry christmas to you! ^_^
Today, after 2 weeks, i removed the original screen protector from the display, and noticed some strange big lines/waves on it: three horizonal lines and one wave on the left side. They are not scratches (and could not be) and the display isn't cracked.
At first i thought it was dirty glue so tried to clean it gently with a bit of soap. They seemed to be gone away. But then when i put a finger on the screen, they reappeared and i noticed that they were invisible only when the screen was completely clean and black. Tried again with more force and soap but without success. I searched and found this thread: http://forum.xda-developers.com/g4/general/screen-coating-issues-t3134029
it's exactly the same problem described here.
In conclusion, as soon as i have time, i will go back to the store and ask for warranty replacement because it seems an oleophobic coating/ screen refining issue.
Has anyone noticed this kind of defect? In my case, it's really evident. Looking more carefully i saw there are at least three more waves like that.

My wiza200 touch screen intermitten

Hi all,
Has anyone experience with a problem when the touch screen intermittently works, especially when you press/hold hard on the sides of the face of the phone. Without pressing down on the side, the top menu (start... x) most of the time are either unresponsive or respond as if you press elsewhere on the screen.
I'm thinking of open up the phone later tonight to troubleshoot, guessing the screen digitizer is loose or, HOPEFULLY NOT, cold solder somewhere. But if you'd heard or faced this problem before or even have an idea on what has caused the problem, I'd like to hear from you. Please help!
Thanks!
Adding info
Oh yeah, did I forget to say that not just the top of the screen, the middle part as worst. The only part of the screen is still responsive is the bottom. If I press down or punctual around the face of the phone tightly enought(?), I'd be able to have the good touch screen for a little while (5... 10 minutes) before it gone weird again.
Fixed... for now
Well, I jammed a couple of thin plastic to the bottom of the screen within the housing facelet behind the t-mobile logo... and it works... for now.
I still intend to disassemble the dawn thing as soon as I realize such quick fix has become unpractical or no longer work.
I will check back to this post again, so if you are interested, don't hesitate to reply, I'll try anything when desperate.
How long have you had the phone?
How do you carry it around?
If you got the phone recently and started carrying it around by putting it in your pants pocket, then you find the screen sometimes doesn't work well, those facts are related. A couple of years ago people used to always complain about this, and some recommended rubbing your finger firmly around all edges of the screen for a temporary fix. Others recommended forcing a business card under the metal at the edges of the screen. I got a leather belt case for mine, and the problem went away.
If you've had the phone for years and it just now started acting up, the problem might be related to a cable, connection, or something. There is a wizard service manual online. I've used its instructions to replace a screen, with no bad issues.
Good luck with your phone. The wizard is a bit old, but still pretty nice.

[Q] Issues after replacing glass: Black out and self typing during calls

Hello all, and XDA developers,
I'm a short time lurker, and flasher, but that's besides the point. I've started my own business repairing phones and I've gotten very good at it, I have extremely fair prices, and this is putting me through college.
I've ran into an issue and I can't figure it out. I try to stay up to date on phones since my job requires that I work on phones, and although I couldn't find all the information about the hardware under the screen of the SGS4 i decided to replace a broken glass screen any way..... well now I have a dissatisfied customer on my hands and i'm doing everything in my power to rectify the situation.
What I did:
I used a heat gun to lightly heat the screen of my customers broken phone, like I have done many times before with other models of phones. I scraped off the old glass, cleaned the glue out thoroughly with alcohol and a small piece of microfiber (like for cleaning screens and glasses). I laid down 3m tape (possibly in the wrong place). Put the new glass on, and PRESTO done.......
The result:
A beautiful new screen, but the wake up motion doesn't work any more (where you swipe your hand across the screen w/o actually touching it), and the screen automatically blacks out once a call is placed. This may be because of where i placed the tape, but a new issue has reared it's ugly head...... It's typing now... by itself.... during calls and at other times. She wanted a different color for the screen and i told her that I will replace the screen and fix the issues all in one motion, but I'm not sure what is making it type on its own. Does anyone have any clue as to what could be causing this issue? I have until the afternoon of 9/25 Central time (UTC-06:00)
Thank you to everyone for existing, this forum, even if it doesn't resolve this issue, is simply a work of art by mad geniuses from all over the planet. I love everyone of you.

Keyboard afterimage/artifact left on my screen

I got my s3's cracked screen get fixed by this guy on ebay. (GLASS ONLY LCD WAS FINE)
But after I got my phone back, there was an afterimage of the keyboard left on the bottom of my screen. I don't see them that well in dark images but on white screens I can see it.
I heard afterimages can be left on AMOLED displays if the image is left on (without refreshing) too long. I think when he was testing my screen, he left the keyboard on for too long. And I also heard this was a permanent mark.
So I emailed him and he replied that this indeed does happen while replacing the glass and his customers have reported this too and this does go away after a while. But, I thought these image artifacts were permanent. O_O Is he just telling me this so he wouldn't have to replace my LCD(which would cost 100~ dollars.)
1) Does this go away? 2) If so, how long does it take ?
2)Does this actually happen when replacing the glass?
Thank you so much!

Cloudy area displayed on white or light screen

I bought my N9 32GB white from Amazon Warehouse on Feb. 17. It was the second I'd ordered. The first had a defect (bent frame). All has seemed well with this--very minimal light bleed; no dead pixels; recessed but clicky buttons; no squishy back--in fact, very solid. For the past two weeks, I've noticed a cloudy area about 1"x1" just below the horizontal midline near the center in portrait mode. It looks like a smudge but remains after I wipe. It's particularly noticeable as I scroll white-background screens. I even changed my Tapatalk app to dark mode to avoid it. I've tried to get a pic of it, but it doesn't show up well enough, if at all.
I came across a similar situation of someone seeing dark areas on light background on his LCD panel laptop after he had sat on it. It was reported that applying extreme pressure to an LCD screen could result in this phenomenon. I have not applied any pressure to the screen, but as it is an open-boxed item, it could have happened.
I need opinions from those who know about these things as I know nothing. ATM, I'm trying to train myself to scroll a page from the center so that my fingers hide the "shadow" which is also what it looks like.
Thanks

Hi, ritchea...
Sounds like you've not had the best of luck with the N9, this being your second one.
From your description it certainly sounds like a hardware defect with the screen. A manufacturing flaw perhaps, or something happened to the device whilst in transit or in storage at the warehouse
If it really bugs you, you should get it replaced.
I'm a little OCD about this kind of thing, and no matter how much you try to convince yourself it's nothing and to avoid looking (at the screen flaw)... subsequently, you spend all your time **thinking** about not looking... And eventually you look.. And wished you hadn't... if that makes sense. It detracts from your enjoyment of the device.
Rgrds,
Ged.
I'm a bit (more than a bit, really) OCD. I've owned over a dozen devices but never experienced this so I also assume a defect. I just needed to know if this is a possible defect that is known-especially when trying to get service.
EDIT: As this thread had had over 200 views, I'm throwing more info out there to see if anyone has any further insight.
I factory reset the tab --all stock except for relocking it. Darn if the spot didn;t seem to disappear. Then it returned. At that point, I decided to revisit the back. Hmmm. There is a little give in it--not spongy, but when I applied some pressure, I heard a sound in the middle of the tab like adhesive reattaching. (I've looked at the teardown and know that a lot of tape exists but not from the back cover to the rest of the tab.) I looked at the white screen, and again, the cloud was gone. In a few minutes, it reappeared. So, I firmly rubbed the mid-back and the cloud disappeared. I've now tried it over a dozen times (after restoring my nandroid), and applying firm pressure to the back always, but temporarily, removes the cloudy area. Can someone say what's most likely causing this? (I know it's faulty hardware, but I mean, what is happening to the screen when I apply pressure? Maybe a bubble in a layer somewhere?
Because of the camera, I don't want to get into taking the back off. I chatted with HTC to make sure my Amazon warehouse tablet was covered, and was told that it is even though (from the CSR) Amazon is not an official HTC retailer.

White line across the screen

I have a very light white line across the screen just below the AOD clock.
Now this line is like a smudge and if i rub on the line it vanishes but after sometime it comes back at exactly the same spot.
I dont know how to explain but it seems like dust line and not something that is inside on the screen.
Is anyone else facing this?
May be its oleophobic coating wearing off..
That's crazy
I just got that today as well. Unless I hadn't noticed it before but my phone is 2 weeks old. I have not dropped it at all
I have the exact same thing on my phone, I also noticed it on my wifes phone.
Same here ..
The AOD clock moves, so your description doesn't quite help.
If you use an app like "Display Tester" to show a black screen, do you see the line?

i also have this issue
it like a white haze, a vertical line across the sides of the screen, before it curves to the sides. i have it both sides however left side is longer. it doesn't look like a scratch or burn-in, it's like a vertical haze that won't get removed with any wiping or cleaning.
its not really noticeable in general, only most noticeable when screen is turned off or when it is displaying black or dark images.
Smudge on screen
I am using Smasung S9 Plus and I don't know what is the proper name for it but i am facing same issue.
Temp Solution : It gives you temp solution by using Touch Screen Wipes and Dry Cotton clothes .
but after one or two days it comes again so i am waiting for permanent solution.
