[Q] OT: Maybe silly question: self-healing display? - Galaxy Tab 3 Q&A, Help & Troubleshooting

Dear All
I encountered today a fascinating issue: taking a P5220 in one hand, I felt a crack under my thumb: the display had very thin cracks and I was shocked, how sensitive it was.
I looked very carefully at it: definitively very thin cracks in at least one or two layers of the display, could be seen clearly by looking from a flat angle. Tried also to "clean it" - definitively cracks in (at least) the surface
After 4 hours they were gone. Completely.
Does anybody know if there's a use of self-healing material? Just out of interest.
If NOT, be warned about the sensitivity of the screen!

[Q] XtremeGuard on XPLAY

So around more than a month ago I ordered one piece of XtremeGuard screen protector off eBay from the official retailer. I just really wanted to give it a try even knowing that the Xperia Play already comes with a shatter-proof film fitted on it. My order didn't arrive within the 20-day period so I requested a refund. They refunded my $4 and to my surprise, the item came this afternoon after more than a month since it was ordered.
Now I'm really thinking twice...
So here are my questions:
1. when installing the XtremeGuard screen protector, do I have to remove first the shatter-proof sheet already fitted on the Play's screen?
2. anyone got a video for the installation of XtremeGuard? I very well understand and speak English but then their instruction material is kinda vague. And knowing that the installation involves water and soap, I think this procedure should be taken seriously since it may damage internal circuitries of the phone. So a video of the installation should really help!
Thanks everyone! Will be waiting for your replies!
Screenguards are generally of varying quality. I haven't heard of that particular brand. However, most screen guards are applied in one of two methods:
1) Sticky/Sticker application. The screenguard has a side with a glue applied. You carefully apply it and hope for the best.
2) AdhesionCling with soap/water/alcohol. Basically you strip off the old guards if you have one, clean the screen, then apply a _very thin_ layer of this soap/water/isopropyl-alcohol solution to the screen. You then apply their clingwrap style of screen guard starting from the top and slowly slide it into place, trying to avoid as many bubbles as possible. You then use a credit card or a supplied squeegee tool to try and squeeze out the bubbles while the liquid is still there. If you are lucky and get them all out, let it dry for 4~12 hours. Then it should be stuck there pretty good until something randomly peels the corner.
With all screenguards there are pros and cons.
Pros:
Less likely to scratch screen. Slight bit more impact resistance against breaking your screen. Some provide anti-glare or even tilt-angle shading for privacy (prevents shoulder surfing, but lowers visible angles).
Cons: Slight to moderate less responsiveness and accuracy from the digitizer (thing that recognizes your fingers). Depending on the material and formulation, you may also have a negative tactile response (gummy or sticky, compared to the bare glass). Buildup of gunk around edges of screenguard (this is particularly prevalent on the whole-device type covers, or ones that aren't touching all the way to the bezels).
I can't prescribe an exact way of doing it, but look for some of the YouTube videos on how to apply the ZAGG screen protectors. They apply with the soap/water/alcohol solutions, so it may be close enough to your type to be similar visual instruction.
whoa thanks for that buddy!
now I'm thinking twice again.. I can live with lesser angled views but with LESS RESPONSIVE DIGITIZER? No way!

Any screen protector will do that. Some do it worse than others. Some do it so slightly that you don't notice it (or you just become adjusted to it over time).
By far my favorite screen protectors are the anti-glares. They don't have that sticky feeling that the BodyGuardz or Zagg ones do, and the viewing angle is butchered. After this anit-glare wears off I will finally also remove the stock one that comes on it. My touch response is very wonky sometimes.
Same deal here I tried the same buyer I'm sure and I had the same problem. Dont use ebay!

[Q] Screen Scratches

Okay, call me confused.... I bought my device on Black Friday and got it some time around Nov 27th. For the first two weeks I owned it, I didn't notice a single scratch on the display, and it seemed to "repel" finger prints (or at least they seemed to clean themselves off after a short period of time). Now, less than two weeks later, I'm seeing tons of long ultrathin scratches (so thin I can't feel them), and one "dent" (about a half mm in diameter) and the fingerprint repulsion property may have decreased.
I've talked to both Sprint and Samsung who are claiming I physically damaged it and its not covered any warranty. Both claim scratches on the glass are extremely rare (one supervisor at Sprint claimed he had never heard of a single incidence of this). I've owned devices with Gorilla Glass before and never had problems like this. Generally speaking I try to be very careful with my phone (in a pocket with nothing else) or on a desk, face up. Of course, I'm not saying I'm a perfect angel about it, but I do try. I only touch the screen with my finger.
Samsung has been all over the map. One person claimed that Samsung recommends a screen protector, another person claimed that "manufacturers usually recommend" a screen protector, and when I asked where in writing they published the recommendation they of course had no answer. The same person who said the "manufacturers usually recommend" also explicitly said I should not expect scratches after 4 weeks without one.
Its almost like there was a hard coating on the surface of the glass that is wearing off and it is becoming far more sensitive to scratches. I keep reading reports about how some phones are highly resistant and some aren't, So... what's the deal with this?
I've had mine since August and no scratches of any kind, without a screen protector.
Then again, I baby my devices. It's either in my hand, on my desk, or in my pocket with nothing else in it. Only my fiance is allowed to use my phone, no one else.
This is a long shot here, but have you tried giving the screen a really careful cleaning? I've had thin streaks of ....maybe grease?.... on the screen that I thought were scratches. After a careful cleaning they disappeared. My SGS3 is about 6 months old now and still no scratches on the screen.
As far as the hardening wearing off, seems unlikely. Its actually a heat treatment to the surface of the glass, not something they spray on. It's part of the glass itself.
I'm pretty sure its not grease... I went over it with my fingernail and I can definitely feel some and there is no deformation of the "scratch." I've also scrubbed it with my shirt. If it was simply grease or something on top of the surface I'm sure it would have wiped away.
I wouldn't say I've babied the phone but I think I've made an intentional effort to be careful with it, especially once I saw the first scratch, but they just seem to be multiplying. I strongly suspect the glass is defective. When searching on it, it seems some people never have scratching problems and others are getting the screen scratched up within hours. It seems to me that the quality of Gorilla Glass is inconsistent, but it also seems like Sprint and Samsung deny the problem exists. So I may be SOL.

I am sorry to here this man, in your post before this you mentioned using your shirt to clean the screen. That is a big no no in my book, i would suggest using a lint free microfiber cloth, and make sure it is dry. I always bye Rayban sunglasses and they tell you never to use your shirt to clean them. I am not saying that's how they occurred but from now on maybe FYI.

[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.

One M9 Prime CE - gap between screen and frame

Hello
I have my HTC One M9 Prime CE for a week. I think it was a good choice, but I noticed one disturbing issue - small gap between screen and frame. This is picture of it:
i.imgur.com/CdmDflW.jpg (sorry for non-clickable link but I haven't 10 posts)
I hope it's clear enough.
There's not any other gaps. This one is very thin, but backlight is clearly visible between the edge of glass and metal frame (not visible if screen is even slightly pressed there). It's possible that dust particles will get between glass and display or will affect backlight? It would be annoying for me. I think that the whole display is bonded and it's not real problem, but I'm not sure.
Of course, my phone is under warranty, however I want to avoid repairs because of a lot of bad opinions.
Thanks for feedback in advance.

"New" and perfect Note 10+ "refurb" - phone perfect but is there any way to test if the factory screen skin is installed?

I ost my Note 10+ a few days ago, a first for me. I immediately considered it found and stolen as I could see the person who found it via GPS, driving about the area where it fell off of my truck. So after two unanswered calls to said phone? I immediately wiped it and so at least my very minor personal data is secured. Whomever it as, *did* happen to get a very extensive, 40,000+ file .flac/.mp3 library on my spare SD Card but that's quite redundantly maintained/backed up so no real loss.
I immediately bought an exact replica of the lost Note 10+ from the same great seller as before, an ebay "excellent" condition refurb. The phone was here in 2 days then a quick visit to the local ATT store and I'm now back in business as usual, taking literally about 20 minutes to have the exact same phone/usage apps/settings and basically a Note 10+ set up precisely as my former phone had been. This is a relative topic with most users, myself included, as each of us may more or less appeciate any given app or feature ... but for me? Google sync and restore is a metaphorical Golden Unicorn(tm) lol.
But to my main question...
How can I determine if the Samsung default screen protector/film is installed on this new "refurb."
The screen on this unit is flawless, having no discernable marks or scratches, not even of the micro variety. But I have noticed that the thumbprint sensor is quite more responsive than my previous Note 10+ which definitely had the stock screen protector as, over the years, it had began to bubble ever so slightly and in certain places.
I've examined the edges of the new screen at great length under more than ample lighting and with very good magnification equipment and can find no visible "seam" or otherwise around the edges and where one would expect to find such a seam for any phone panel that had one of those super thin, super transparent protectors installed.
I will say that I found the stock Samsung protector on my first Note 10+ to be quite good, as good as any of the "tempered glass" varieties I'd used with previous phones though after two years of fairly rough use, there were small areas appearing where the Samsung factory screen film was beginning to show it's natural limitations.
So any ideas short of close examination with a good light source and high quality magnifying glasses would be welcome. If I do determine it is completely lacking in the inclusion of the factory installed panel film/protector (only reason I can imagine is if the previous user had removed it) then I will of course want to begin researching an appropriate 3rd party option that works well while maintaining solid use of the fingerprint sensor...
So any tips would be welcome...
Thanks in advance,
Joel Harris
The front cam hole will likely have a cut out in the screen protector if present. Slight seams are visible on one or more of the edges. Also the glass feels different than any plastic protector. Gorilla IQ Sheild is a good wet apply protector.

Most likely, Being a refurb with flawless screen, it probably had it's screen replaced and replacement screens don't ship with that Samsung factory screen protector on them. Most likely no screen protector in place

Thanks mate ...
Checked all the obvious variables and there's def no protector on the screen.
I found tons of "IQ Shield" variants on Amazon but none specifically made by Gorilla, which is a brand I tend to trust. Any further info?
In the interim, I bought this uber cheap but very well reviewed cheapo. If it works half as good as the reviews seem to indicate then it should be fine.
Thanks again ....

Get a couple, just in case. Things must be as dust free as possible ie spotless on the glass and room where applied. Don't touch the glass or back surface of the protector. Use enough of the fluid to get it aligned spot then work the air bubbles out. Watch it to make sure it stays adhered to the curve portions of the screen.
Just press and briefly hold if it lifts up. Use a little of the fluid if needed. If it ever lifts up on the sides later as long as no dust or dirt get under it, it can be reattached with a little water and pressing it down.
Leave it set up for at least a couple hours before using if possible. Mind the edges don't lift, usually after 10 minutes that's no longer an issue. Any small micro bubbles will be absorb in a few days... not big air bubbles though.
The Zizo Bolt is an excellent case for it.
That's all I use, zero damage in almost 3 years.
Enjoy, the Beast is a great phone!

Thanks for the detailed tips, friend. Much appreciated. But exactly what screen protector are you referring to? The originally mentioned "Q Shield" variant? Or the one I mentioned already ordering, which is the Apiker random find off of Amazon.
If you're referring to a specific brand/model of protector, be it of the "Q Shield" sort or otherwise? Please send me a link if your able to do so.
As it turns out? The randomly ordered Apiker kit I bought from Amazon based solely on user reviews alone, has turned out to be pretty okay. As with many such products, especially those for phones with curved edges, there really is value in going over some install videos and what not but the first application turned out pretty damn good.
The kit came with 4 of everything so for the money and the fact that 2nd and further applications would of course be more intuitive, makes it a decent value.
Also, the Apiker screen kit I bought is not tempered glass but some other sort of material but still has a decent feel overall. The main thing I like is the thumb sensor is still every bit as sensitive/responsive as it was when using the naked, glass screen.
But send me some info on the kit you were referring to that uses what you called "fluid" ... I'll get one of those too lol!
And yeah, mang. Note10+ FTW! Mine was stolen about a week ago .. only time I've ever lost it ... but it wasn't 20 minutes before I'd ordered a new "refurb" off Ebay which I'm currently using now.
I tend to always buy whatever the flagship Sammy was 3 or so years ago and always end up saving tons of money and being very happy with whatever that ends up being. I bought a 1 day temp new Galaxy A12 at the local ATT shop to use till the Note10+ replacement came in and the Note10+ processing speed is WAY better than the A12, which frankly was just a sluggish dog in comparison.
Thanks again for the info..
