Finger wear on the screen? - Galaxy Tab S Q&A, Help & Troubleshooting

I have some marks on the screen and they do look like finger marks, but I've tried cleaning using various strengths of isopropyl alcohol and water without any success.
Is the glass worn and is there anything I can do, I've done the usual searches but it's all about finger marks that are removed easily? The marks cannot be seen at all when the tablet is switched on but I'm not sure what to do as I'm thinking about putting it up for sale and wasn't sure whether to mention this?
Photo attached, the flash from my camera does make them look pretty bad but in daylight the screen has to be moved to catch the light for the marks to be seen.
Thanks

oil slick screen

had my TP2 nearly a year but recently i have noticed the screen has like a rectangle shape oil slick type mark on itvery noticable and seems to be getting worse anyone else had this??
its as though there's water under the screen protector but when i remove the SC its still there
search newton ring.
newtons ring??? kind of the case. the "oil slick" is mearly trapped condensation between the digitizer and the top plastic covering that you catually touch(the plastic you put the screen protector on). moisture seeps in through the bottom keys and earpiece in forms of vapor and liquid. this occurs when you have your phone in your pocket or use it in humidity(shower or weather)...congrats, you ve trapped your sweat lol. the reason why its rectangle is because the screen/digitizer and top plastic are not set flush together. as you know, the top plastic is very flexable so you can take your finger and feel the various componets in the empty spaces. i can confirm my finding because a few months back, i replaced my tp2 screen. i seen it had the oil slick before i opened it and before i put humpty back together again, i wiped under the plastic screen and felt a slight moist film. i tried to guess how the hell water got in and i concluded by a salty electronic taste...yeah i smelt and tasted it...that it was sweat. i always carried my phone in my front pocket and over time, the sweat built up. after a wipe with electronic cleaning cloths, an air dry and then an air can blow(i love my phone lol), i put it back together and bam...no oil slick. another way to think of my theory is, you know when you swim with your watch and condensation builds up on the inner quartz and makes it look foggy?...same thing here. only thing different is that there is only one flat surface and not 2 like inside the phone so the moisture wont look like an oil spill, it will just be foggy.
so how do i open the screen up to get rid is it easy enough to do or will bloww warm air over it do it ???

there are lots of vids on how to disassemble the tp2. check youtube. just to let you know, its a long process. you have to take apart the entire phone just to get to the screen...good luck.
ps i would post the vid link but im typing this off my tp2. if you cant find a good video, i will link one here later.
check my skydrive for the dissasembly doc

Clicking on rear

Don't know if I am paranoid or not, but there is a slight "click" if I rub my finger on the back of the phone. It is almost like there is just a slight space between the back casing and the innards of the phone. When applying pressure it just touches the two surfaces.
Is anyone else experiencing this...is it cause for concern or just normal operating conditions?
Thank you.
Nothing on my end here... Been wiping it like crazy when I was trying to put screen protector on the back and no clicks here. Same when I was pressing it as I also saw similar issues on talk.sonymobile.com.
Having the same thing here too. Altough i wouldn't be too alarmed. Im pretty certain it's just the plastic casing on the back thats moving a bit.

[Q] Flaw, fracture or potential screen crack; Should I be concerned about this?

Hi, guys...
After spending fours years tinkering around with budget to mid-range Android devices, last month I decided to treat myself to a top-of-the range, flagship device... and four weeks ago I bought (off contract) the HTC One M8. And I am absolutely delighted it with it... it is truly an amazing piece of technology.
However, a few days ago, when cleaning the screen, I noticed a mark... which I just assumed was a finger mark or something. I wiped it away, and it was gone...
...or so I thought...
A day or so later, I notced that the mark had returned... in exactly the same place. It's in the very upper right hand corner of the screen, to the right of the front facing camera and to the left of the SD card tray.
The mark is in the shape of an elongated 'S'.
--------------------------------------------------------------------------------
A few things puzzle me about this mark or blemish...
** It can only be easily seen in specific lighting conditions, ie., when the light source is hitting the screen at an oblique angle...
** It's less noticeable in natural daylight, then in artificial light...
** It's totally invisible when that of part of the screen has just been cleaned.
In other words, in order to see this mark/blemish, I have to deliberately 'dirty-up' that part of the screen. Either by rubbing the screen with my thumb or finger to leave some sweaty residue, or by lightly breathing on the screen, the way one would on a pair of spectacles in order to clean them. Indeed, this was how the blemish came to my attention. I normally lightly breathe on the screen, and then wipe it with a soft microfiber cloth. I suspect that the presence of finger grease or breathed water vapour is altering the refractive index of the glass, such that reflected light is making this blemish or flaw visible. But that's just an educated guess... it's been 35 years since I studied optics for my physics 'O' level at school. Funny how some things stay with you though.
--------------------------------------------------------------------------------
I have appended three screenshots of this strange blemish or mark. It should be noted that getting these shots was extremely difficult, as the light source had to be angled obliquely to the screen of the M8 for the mark to become clearly visible to the camera I was using. I took over sixty shots, and these are the best three.
Ironically, and despite these difficulties, these three shots make the blemish look much worse than it actually is. In normal use, I've got to look really hard for the blemish to actually see it. If you didn't know it was there, you likely wouldn't see it... or you'd just dismiss it as a smudge of grease.
--------------------------------------------------------------------------------
So, what exactly could this mark or blemish be?
A manufacturing defect of some kind?; Some natural flaw in the Gorrilla Glass?
If this is indeed the case, then I can relax and live with it. The mark is borderline invisible anyway, and doesn't impact my normal use of the device in any way.
Unless it's the portender of something much more serious, such as...
A fracture inside the glass? - And this is what worries me.
It's not a crack (yet... and it may never be)), and when I run my finger nail over the area affected, I can not detect a crack. The glass feels consistently smooth. Whatever it is, it's 'inside' the glass itself.
However, if it is a fracture, then what are the chances of it propagating into a full blown crack at some point in the future?
Have any XDA members seen anything similar on other devices they've owned?
Should I pre-emptively initiate RMA proceedings with HTC before it does becomes a crack? Or am I worrying unnessarily? I know I can get a little OCD/obsessive about details like this, and I tend to loose perspective a little.
So... any thoughts, insights, recommendations or advice would be warmly welcomed.
Thanks in advance.
Rgrds,
Ged.
if it really bothers you, take it back to where you got it from and ask for a replacement.
i don't know exactly what it is, but it does appear to be a defect of some sort.

"Spot" on top-right of screen glass near camera won't stay clean?

On my N7, I noticed I have a square area of about 2" that seems to pick up fingerprints aggressively; more so than the rest of the screen.
Not particularly sure what's up with that part of the screen. I tried using some water and soap, and also 91% isopropyl alcohol to clean it up, but it didn't help.
Can't really take a picture of it right now, but I'll try to later.
Was wondering if anyone else had a similar thing going on?

Question Got some permanent stains on the Display

Hey everbody,
I got some stains on the display that cannot be removed any more. If you move over them with the finger tip, you can feel a unevenness down. I have no idea where they could have been from.
What do u guys think. Im usually really careful with my smartphone.
I am by no means an expert first and foremost.
But when I have something I can't get off my glasses with regular cleaning, I will use some toothpaste and a soft microfiber cloth and that has just the right abrasiveness to get whatever is on my glasses off them. Granted there's more cleaning involved but it works for me

Thanks mate. But im pretty sure these are tiny "holes" in the top layer of the display.

I think that you have not been careful enough and somehow damaged your display. It's possible that you only damaged the oleophobic coating, and not the underlying glass (should be easy to tell by looking at the display when it's ON - do the pixels underneath the damage still work?).
There is no other explanation to this, at least not from the looks of it (since you talk about "a[sic] unevenness down" - implying not superficial stains, but serious damage). There are extremely rare instances where displays damage themselves ("spontaneous shatter") but that is another matter entirely and has nothing to do with your - apparent - circular damages (since those lead to the shatter of the entire tempered glass). I'd wager either fire or acid or something else destructive happened here, but only you can tell.
Fire damage leaves a distinctive mark
Gorilla Glas Victus has a 6-7 on Mohs scale of hardness, you can pick whatever might have been your problem:
I have the same issue, appeared two days ago. I have one small one that looks the same as your small ones, On mine the mark is under the top glass, it almost looks like dust under an applied screen protector. If I look at it at 180 deg for the mark I can't see it at all, not until i move about 5 deg off 180, then at about a 45 deg angle it dissapears again.
To me that very big one looks like damage to the top surface, then the others look like they are below the glass
did you possibly get alcohol on the screen that dried up? I have something similar that happened to my screen and the only thing I can remember that possibly got on my screen was alcohol. I woke up the next day and noticed the spots on my phone but only when the screen is off

Alcohol is bad for the phone's display because it'll heat up the display and the glue inside will lose its stickiness. This causes the display to fall out or some damages like this cause the display to burn inside and show like this!
@randylahey786 Why in all heavens should alcohol heat up the display unless you burn it on the display/phone ? ..... and just for the record: i have been using isopropanol since ages to clean glasses, binoculars and, yes, also smartphone displays. BTW the nice tabs provided with many display protectors for cleaning the display are just alcohol swabs as well.....

I have seen issues with some people who have used sanitizer to clean the display and the display came out! Sanitizer contains alcohol in it, also isopropanol comes as a cleaning liquid especially for phones so they would've tested it but sanitizer or alcohol drinks are worst!

I agree, as you never know what stuff is included in those sanitizers and of course alcoholic drinks may include sugar and other ingredients that could leave residue on the screen after drying out.
I always get pure isopropanol for cleaning purposes, this way I know it's safe to use
Quite a few people on r/GooglePixel have had the same issue upon release - it's been speculated that it's something to do with the oleophobic coating not adhering to the glass & is a manufacturing fault.
I would contact Google and see if they will replace the device for you as it will probably get worse over time.
it looks like your oleophobic coating has been removed. Can you post some different photos? Do you have another smartphone you can add to the photo? Your display looks very dull (but it could be the photo).
I recommend the toothpaste and micro fiber trick the other comment suggested. then grab some oleophobic spray and coat your screen again. It takes 2 or 3 coatings to get it even but it works well. Unfortunately coating isn't covered in Google's Official Warranty (it says its not on their website). There's a good oleophobic brand that many people use and they swear by it but I forget the name.
But I would get the display even and unform first before doing anything - maybe even using a polisher tool with a really soft brush. Someone did this on reddit on their 6 Pro a few months ago to remove scratches and it worked really well.
I would also try to get as many reddit and xda posts as you can and document them, then contact Google and see what they can do. Also maybe try going to your nearest UbreakIfixit - see what they say? They see hundreds of different phones a day. But there seems to be over 15 posts on reddit that shows the same type of "Spotting" or "blotches" that appear on the 6 / 6 Pro. Not sure what exactly is going on there but some have gotten their devices replaced if I remember correctly (but others were told to kick rocks by google support, so make sure you prepare yourself before calling).

Neither sanitizer nor alcohol belong on a display. If people damage their phones on purpose or through the sheer act of incompetence, Google is hardly at fault... a phones display should only be cleaned with a fine microfiber cloth - and if the display is too dirty, only a special display cleaner should be used. Even that however should never be DIRECTLY applied to the display, but only used on a microfiber cloth again, which is then used in a slightly wet state to clean the display.
Since I know people, and people do stuff like that (smashing glasses cleaning cloth drenched in alcohol, sanitizer or something like that onto their phones), it's hard to judge/evaluate these threads here. Often it just seems like something that can easily be caused by a user, and is probably not a hardware issue.

was wondering if you tried google support at all, just to see what they would say. there's other instances of "blotching" on reddit on the Google Pixel forum. Do you know how it might have happened now that its been a few more days>?

Same issue. It was caused by dripping some salsa on the screen at a restaurant and didn't notice it right away. First time I've ever had anything like this happen to a phone screen.
