Smudge on lower right corner - Sony Xperia Z Ultra

Ok, firstly I'll admit that I suffer from a certain level of OCD when it comes to phones. I ordered a GPE last week and was very impressed with the phone. The size is a bit large, but everything else, except for the camera, is phenomenal with this phone.
However, about one week after I got the phone, I noticed what can best be described as a smudge on the front lower right corner, about the radius of a quarter. Granted, since it is at the corner, the total size would be a quarter of a quarter. Anyway, it is usually hard to see it unless you run your finger over the area, whereby the spot becomes clearly visible. I don't know if it is a scratch on the screen protector, but I can't feel any texture and light doesn't seem to show any micro abrasions. It almost seems to be under the screen protector.
Anyway, the unit also had a weird creak on the back of the phone (pressing it in an area would make the phone creak), so I asked for a replacement unit. I got it yesterday and what do you know, the smudge is there on the new unit, too! So my question to other Z Ultra owners is whether this is a common thing and secondly, whether it is an issue with the screen protector only, not some damage to the screen.
The best way I can describe it is as if someone applied pressure on the corner leaving a mark. Again, it is really hard to see if the screen is clean, but becomes easily visible if you smudge the corner with your finger - a clearly visible quarter-circle will become visible if your phone is like mine. Thanks for your help. BTW, I'm going to keep my phone unless it turns out that the smudge is some kind of pressure damage.

The anti finger print coating wears off real fast on the xzu, only way to solve this is to either remove the sony screen protector or apply another screen protector on top of it. Mine wore out in a week, and your replacement gpu is most likely a used defective unit being refurbished. The reason why the smudge is on the lower right corner is because that's the area you use most often....for scrolling and unlocking the screen, hence the wear out

I'm not so sure my replacement unit is a refurbished one. I believe Google has a policy to replace phones with new devices. Also, it is basically the exact place and shape as the smudge on my previous phone, and this unit has been used for only a bit more than 24 hours. The smudge starts at the lower right corner of the glass on the front of the device and goes as far as barely short of the actual display portion of the glass slab.
With sample of two devices, it seems to be a result of the manufacturing process because the two are so similar. Just weird. I guess if it really gets under my skin I'll try to remove the film.

I had the same thing, only in the lower left corner, but i got my screen replaced (for a different reason), and the screen protector i got on the new display is looking good. It's only the oleophobic coating that's wearing off, but i understand how that can be incredible annoying.

Believe what you want to believe. Although I'm telling you its a used device...do you really think they'll thrash all units sent back and dispatch new ones every time someone RMA their phone. Anyways, the solution have been stated out for you, choose what floats your boat

I suppose that theory is as good as any. Nice device anyway. Thanks for the reply!

Yes you can hide it.
apply any screen protector on top. The sh!tty smudge will not visible any more.

Sorry to necro this old thread.
I just wanted to add that I have the exact same issue. Noticed it today while going to show someone it.
I've been babying the heck out of the phone to prevent this issue, but unfortunately my screen protector and case won't show up until a few days from now.
I'm hoping applying the screen protector over it is all I need to do.
I figured I'd post in this thread in case someone else also had this issue and was unaware of this common issue.

Smudge in up left corner
Hi.Just bought this phone and when i clean the screen from fingerprints i see a smudge or mark or whatever its called about 1 x 1 cm in the left up corner.Is it normal?
If you look carefully it seems to be from inside and it doesnt leave.You can see it better only when you pass over it with a towel while cleaning the screen.
Is it something with antistutter film?Warranty covers it?
Thanks in advance

I have it also, 1 day old phone. Hard to believe it is wear.

Is my screen broken?

These past few days, I've been noticing unresponsiveness to touch in a certain part of my screen. This screenshot shows what I mean. I never lifted my finger while drawing, and I swiped up and down continuously. The middle band of unmarked screen seems to be failing and only works when pressed harder. Am I going to have to get it repaired? I'm tempted to use this as an excuse to jump to the G4 when it comes out but I'd rather get this fixed if there's any way I can do it

I recently broke my screen glass and digitizer. I had a region that was vertically oriented that didn't work over the rest of the screen. It is possible that the digitizer or maybe connections to the digitizer are broken. I ended up buying a new screen, as it comes with the digitizer and glass. Reading about it sounded like a huge pain to even think about just replacing the digitizer and glass. The new screen was around $70-80 on Amazon. Process was well documented on iFixit and youtube. The only problem I had was that I didn't receive my order of adhesive tape and didn't want to wait. Now I have a 1 inch area that leaks light. I can live with it until I decide it is worth cracking open again to properly seal it up.

Review of the Amfilm Full edge to edge screen protector

Ok so I got this today (surprised because it just mailed yesterday)
https://www.amazon.com/gp/aw/d/B01CDVZAH6/ref=yo_ii_img?ie=UTF8&psc=1
So as far as fitment goes, it fits perfect. It allows for the Spigen thin fit case to go on just fine. It covers all the areas of the screen. I am however not a fan that the camera does not have a cutout.
Secondly I am most definitely not a fan of the dot matrix on the display. It doesn't detract from the screen when on but it definitely is noticeable when off.
Third, touch sensitivity is definitely inhibited in the bottom right corner of the protector (hitting return or smilies). Also, it's hard to bring up Samsung Pay easy pay feature as well.
Fourth, when typing there is a slight sound of the protector hitting the screen (I don't think there is adhesive on the screen part and only on the black areas).
I really had high hopes for this protector but overall I'm a bit meh with it. I want just glassglass, clear no dot matrix and adheres. I might try a regular just part of the flat glass.
EDIT
After running the protector now for a couple of days I can honestly say I am going to get rid of this and based on other reviews out right now, go with a plastic protector.
I went out yesterday and it was a nice sunny day. I pulled my phone out and immediately saw the dot matrix display even with the phone on (and it actually made it a little more difficult to see things).
EDIT 4/4/16
I got the new updated version of the protector. They have done some things to try and improve it and it is marginally better than before but the deractors are still there.
Touch issues still present in the bottom right and along bottom edge of the screen, dot matrix still there (albeit a lot less pronounced than before). It definitely is thinner than before (but still thick enough to notice when touching the home key.
All that aside, it is definitely one that I can deal with for a while until something else comes along
The search for something that fits continues!

Just got mine.. Got it installed & then immediately ripped the piece of **** right back off.. I can echo all the same negatives & then add that it is thick enough that it was difficult to get the fingerprint scanner to work. The adhesive is a sticker that is indeed placed just around the black parts. Also of note is that this DOES NOT contour to the screen. It is just blackened where you would otherwise see the halo effect.
Bummer. I had high hopes here. Guess I'm glad I never got a reply when I emailed them as per their instructions.

lol I never saw that deal till afterwards. I paid full price for mine.. I have requested a return on this thing. So not worth the money. the ones that dont give full coverage would be better.

Since I didn't pay for it, I'm going to leave it on until I can find a partial coverage one that works.
Just received mine too. Similar thoughts.
What I like:
- The ports and cutouts line up very well with the device.
- Screen is very smooth and feels much like the actual screen itself
- Did not degrade touch sensitivity for me. Sounds like this might be hit or miss, but for me I didn't notice any difference, I specifically tested corners and borders. ** After more use, I have noticed degraded touch sensitivity along the corners and lower portion of the screen
- Fairly thick, I prefer this but this is subjective
What wasn't so great:
- Dot pattern can be seen and is very noticeable. Not nearly as noticeable when the screen is on however.
- Adhesive only on the edges and bezel areas. Again, for mine it does not make any noises when I tap the screen but I also would prefer a screen protector that adheres to the entire screen.
- ** Decreased touch sensitivity
Overall assessment: A few minor issues but I'll definitely be keeping it on. For those who use the fingerprint reader, it may not be the best choice it makes just enough of a thickness difference to make the home button actuation feel different. I like the thickness however, and it actually matches the Samsung clear case very well.

Updated my review with thoughts on outside usage. This is not that great when trying to view your phone in sunlight.

Let me know. I received one of the first "freebie" ones....ended up taking it off, as I couldn't deal with the dot matrix combined with the missed taps I was experiencing. Never got anything else about a new version, so I guess you're a lucky 2 time guinea-pig

Glad to hear it's better than it was. I've since moved to the S7 Edge. Unfortunately, seems nobody has been able to make a competent Tempered screen protector for that device lol.

White Shiny Stain On The Screen

I don't know why this happened. I'm using the tempered glass screen cover. Can anyone say what it this and what should I do?
http://i.hizliresim.com/NpqM9P.jpg
http://i.hizliresim.com/m3PvrV.jpg
Run some of the extra tools in AnTuTu to check if it's an actual screen problem.
Might be a "bubble" under the screen protector - can you "move" it with your finger when applying pressure?
Is it a spot where the screen is brighter? If so, I think it's a defect related to the backlight. I bought a cheap replacement screen for my Nexus 5 when I broke my original one and over time it's developed more and more bright areas. I suspect something is delaminating causing uneven backlighting. I believe it can also happen due to water/liquid damage, but in my case phone phone did not get wet.
Actually, I just tried twisting my phone and also applying pressure to the screen and noticed the LCD reacts (flashes) in those areas when I press hard, so I think it may be an issue with the LCD panel itself, not the backlight. In any case, I doubt there's much you can do about it, and be warned it could get worse (I used to have a spot or two near the bottom of my screen, but now I have them all over the screen.) In my case I've just learned to live with it, telling myself having paid $35 for a screen which developed this problem is a lot better than living with a cracked screen, and I'll have a new phone soon, but I would not expect this problem with a new phone.

S9+ oleophobic coating wearing off

I bought my S9+ (SM-G9650 DS) back in April 2018 but these days I've noticed 3 lines that disappear when you clean the screen with microfiber cloth but reappears with my oil skin or water. I've read that it was the oleophobic coating also some guy on Reddit got his device fixed and a Samsung employee told him that it was a defective batch https://www.reddit.com/r/GalaxyS9/comments/8g534o/oleophobic_coating_wearing_off/
I hope Samsung Ecuador replace my screen or give me an replacement.

Try bringing it to an authorized service center. Had a local unit in Philippines have this same issue and they offered to replace the screen and battery.
Two months and 3 weeks with the GS9 + and I'm seeing oleophobic coating wearing off on the spots where thumb is used for scrolling. Not directly visible for now but when applying some drops of water and spreading on the screen can easily show where its wearing off.

Its a problem out here. Service center guys will replace the screen after keeping the phone with them for 1, 2 days but in the process they end up damaging/scratching the phone and then its a never ending process of follow ups . It happened so with my old galaxy s6 edge plus.

I don't have this issue over the main screen (yet) after about the same duration of use as you, but I've noticed it similar to this user here:
https://www.youtube.com/watch?v=qtDf53wcgmc
I certainly don't have it as bad as him and he also seems to demonstrate it over the main screen, rather than just the sides and the top left. I definitely have it over both the sides (around the curved edges) and the very top left area. What I'm curious about is whether I had it from the very start (you won't notice it until you "dirty" the screen a bit and have the right lighting and viewing conditions) as I don't think it's worsened since I first noticed it 2-3 weeks ago. However, it seems there are more reports of people noticing it get worse, which is not a good.
Do you think this is definitely a new thing or could it have been there from the start?
This is without a screen protector? Scary
Mmmm. I have had this problem with every samsung phone since the note 5, gs7 edge, gs8, gs8 plus, note 8. Now the gs9 plus . I notice it happens if use alcohol base products like hand sanitizer, etc and then use ur phone the OC starts to waredown. My gs9 plus looks really bad in sunlight cause of this reason. The only way to realive this problem would be to hide it with a water base screen protector or whitedome tempered glass.

I've owned every Galaxy S series smartphone in the past and each one suffered from this oleophobic coating getting removed exactly where the fingers constantly touch(especially the thumb) without the use of any alcohol or any other solution whatsoever and as I never used screen protectors. But S9 plus took the shortest time amongst them if I remember correctly and since currently its not visible yet from any direction or lighting condition without pouring water there, I ended up installing a tempered glass.
I've noticed this in two spots on my Galaxy S9+. A vertical streak in the upper left corner and a vertical streak on the middle-right.
They're not near the rounded part of the edge. They're not where my fingers reach. I think it was always like that but I only noticed recently. And in the brighter summer sun, it's VERY noticeable now.
Not sure of the best way to get it replaced.
Bought it through T-Mobile. Do I take it to them to replace? UBreakIFix? Or any other Samsung authorized repair place like the specific Best Buy ones?

Can you show a pic ? Just asking.
..
Clearly feels like QC issues in your case. Rather ask for replacement than going for repairing and such.
Sure. It's not the easiest thing to photograph. You have to get the reflection just right. But you can see here when I smear my palm across the upper corner and the sides, there's a toothpick-sized streak that doesn't get any fingerprints on it. And in the bright sunlight it's really noticeable.

Yeah its seen clearly. You should Ask T-Mobile for a replacement I would say,
Sorry for late reply but I got my phone repaired for free at Samsung Customer Service, if you also have problems with your oleophobic coating go inmediately and they should give you a new device or at least a screen replacement.
In my case the receptionist didn't understand what the oleophobic coating was and she said that my phone doesn't have any issues so you should try to convince her/him by using a flashlight to highlight the lines/smudges on the screen are still there even after they cleaned it with a microfiber cloth.
I received the phone after 4 days and they had also changed the battery and the buttons without any extra charge.
PD: English isn't my main language so feel free to correct my grammar if I've made any mistake or you doesn't understand me.

Hi what's the process? How much did it cost you? Mine has streaks on it. Looks like a tree branch. Thanks in advance
If they consider it as a manufacturing error, the repair will be free of course. Otherwise, screen replacement is around 200€.

Question Screen with somekind of problem? could be a screen displacment?

Hello all.
Have received my Pixel 6 yesterday. During the day i notice a smudge on the screen, first i thought that was something dirt with the use. But after cleaning it a few moments later the smudge appears again in the same spot. (pictures of it in attachament)
I need from to know if this is the screen ungluing from the device, if that's the case im returning the equipment, but, again i have to be sure about it.
Thanks in advance for any help i could get.
Cheers

I don't know what is causing that, but regardless, you should return it, in my opinion.
Had a similar problem with my OnePlus 7 Pro. By default new screens have a anti-fingerprint protection. In your case, for some reason, it is gone on one spot. That's why it reappears after cleaning.

The fact that cleaning it makes the blemish disappear temporarily means that the blemish is at the surface and not within the screen. There is no issue between the layers.
As above has suggested, its probably something going wrong with the anti-smudge coating. Could have been a manufacturing defect, or more likely, there has been something abrasive in contact with it, maybe in your pocket.
Actually on second look, that smudge pattern looks like the path your thumb would follow while scrolling.
Do you use hand sanitizer frequently? That stuff can dissolve anti-smudge coatings.
I have similar problem with my LCD and I'm planning to send it to google store repair shop (don't know if I can use mailboxde service for warranty since I'm in Croatia?).
So, there's a circle in the middle of LCD and I cannot wipe it, seems like a glue between touch and LCD. I hope they will approve the defection.
