Howdy folks! I'm new to XDA, I just bought myself a T-Mobile Vibrant and I'm ready to get under the hood of an Android phone and tinker around a bit. Unfortunately, I'm a busy engineering student and I don't have any significant programming skills yet, or time to develop them. However I have completed a project that I hope will be of use to some of the members here.
Preface
A few weeks ago I managed to scratch my screen quite badly. From the impressions I got from reading about Gorilla Glass, I assumed that I could get away with not having a screen cover for a little while. It turns out that this was a very bad idea. While Gorilla Glass is very tough, even if you are careful with it, there are situations where it can get scratched quite easily. I accidentally put a plastic credit card style hotel key in the same pocket with my phone. I am very anal about my screen and I check it for scratches each time I put in my pocket. After about twenty minutes of the hotel key being in my pocket with the phone, the screen went from completely flawless to very badly scratched. There was no metal on the card; it was entirely plastic. My theory is that some grit became trapped between the card and the screen. Either way, it goes to show that Gorilla glass is not impervious to damage.
Shots of the damage:

As you can see there were several deep scratches and many more scuffs. Many of them were visible when the phone was on and caused ugly lines of distorted color. I'm afraid I forgot to take pics of the phone with the screen on before I started the repairs, but you can see what I'm talking about in the later pictures. This kind of screen condition is, IMHO unacceptable. I called up Samsung and they said it would be 160$ to repair the damage. The entire AMOLED screen has to be replaced because the glass is built in. Even though the information I was able to gather about gorilla glass polishing was less than encouraging, I figured that I may as well give it a shot. Worst case, I ruined the screen. The tech support guy confirmed that the Vibrant, (and I assume all galaxy S phones) have no coating of any kind, it's just glass.
Part 1: Materials and Preparation
Looking around I learned that some people had had some success polishing their non-Gorilla Glass iPhones with an industrial glass polishing compound called cerium oxide. I called around town to several windshield repair specialists and found someone who was nice enough to give me some for free! If you don't have as good luck you'll need to buy it online, because as far as I could tell it is not carried in stores. It can be purchased from Amazon
Some of the iPhone polishing guides mentioned that high grit sandpaper is useful to polish out deeper scratches. I went up to an Auto Zone and purchased a pack of 1000, 1500, 2000 grit wet dry sandpaper as well.
Even though the phone has a seal around the screen, I figured it would be worth it to tape up the edges with electrical tape. At the very least this needs to be done to the speaker. I found that the electrical tape worked extremely well, and left no annoying residue.
P.4
Part 2: Sanding
The second step is to sand the screen's phone down. The objective of this part is to remove the top layer of glass that has the scratches in it. This part is important as the polish is not abrasive enough to eliminate any but the lightest scratches.
Guides for polishing older iPhones warn you to go very easy on this part and say that you expect to significant result in about ten seconds. This is not true with Gorilla Glass. On my first attempt I went at it very hard with 1000 grit for several hours. This proved to be entirely insufficient:
P.5
P.6
As you can see I got a little bit of a scuff going, but was unable to remove enough of the top layer of glass to get rid any of the remotely deep scratches. You can see in the second picture that most of the scratches can be seen in spite of the scuff marks. In order for this screen to turn out properly, the old scratches need to be completely obliterated by the finer scuff marks. After I polished out my first attempt, it was clear that I had made very little progress. Application of a screen protector (not pictured) only exacerbated the deep scratches, due to the fact that an air pocket was created in the groves from the scratches.
P.7
P.8
So I gave it another shot. This time I went down to 800 grit and pressed down as hard as I dared without breaking the screen. In order to avoid excessively polishing one area and getting lensing I kept moving over the entire screen. There are two things to note here. First, keep the sand paper wet. Make a puddle of water on the screen that you can use to quickly rewet your sandpaper. I tried dry sanding, but that wasn't any faster and introduced a few new scratches that required more polishing to get out. Keeping the paper wet seems to alleviate this issue. Second, Gorilla Glass with eat your sand paper for breakfast. It will lose most of it ability to affect the screen after a few seconds. I cut my sheet of sandpaper into one inch squares and switched about every ten seconds. This seemed to help things go faster.
After a looong time, the original scratches were almost gone and the screen has a nice matte finish. This took several hours. This next pic compares properly sanded surface to polished surface in the center. Notice that the original scratches are no longer visible and that the unpolished surface has a nice homogenous texture.
P.9
I stopped sanding when the deepest scratches were almost but not completely gone. The key here is to smooth them out enough so that you don't have rough edges that diffract the screen light. If you have done it right, the scratches with be so shallow and polished that there will be no air gap created under the protector, and they will disappear completely.
Because the sanding takes so long, I suggest experimenting with something a bit harder than sandpaper. 800 or 1000 grit diamond polishing compound would probably be more effective. This stuff is designed for polishing metal, so it might do the trick.
Part 3: Polishing
On to the polishing! You will need to use a drill press, drill or some kind of rotary tool or else this part will simply take too long. I used a rotary tool with a felt wheel. This part took some tweaking to get right. You want to have a bowl of water and a bowl of cerium oxide mix handy. Mix a bit of water into the cerium oxide until you have a nice thick texture with no lumps in it. Dip the rotary tool in the cerium oxide water mixture, and start it up before you pull it all the way out of the bowl or else the polish will go everywhere. Also, dab a bit of polish and water on the phone and mix it together into a very thin mix. You can pull a bit of this into your work area from time to time to keep your polishing pad from drying out. This takes some finesse, but you will have plenty of time to perfect it. Again, you will need to press down very hard to get results. Gorilla Glass is very tough! This will generate a good amount of heat, so keep moving and touch the screen every so often to make sure you don't cook the phone's innards! Also, I recommend getting some kind of cloth bit if you can. The felt wasn't durable enough and disintegrated easily.
P.10
This will take quite a while, but if you keep at it, the scuff should start to give way to a nice shine like you see in P.9. I turned it on to make sure it still worked from time to time. Notice the pink areas where I have not begun to polish yet.
P.11
Here, I am very nearly finished with the process. There is still some polish to be done near the edge. At this point I abandoned the electrical tape except for on the speaker so I could get closer to the edge of the phone. Happily, it caused no problems!
P.12
It’s a little dirty, but the scratches are almost gone.
When I had finished, there were still some very slight "orange skin" looking areas in the glass when you held it up to the light, but it was all smooth. That is the key. The protector will eliminate this "orange skin" effect.
P.13
After application of the screen protector, (I used a REALOOK, it's fantastic. Other members have attested to this.) Few scratches were visible, and those that were could only be seen when the phone was viewed in just the right light. The photographs exaggerate them, but it really does look perfect when the screen is on, which is mission accomplished in my book!
Pics P.14 through P.17 were taken with the protector installed. Note that a lot of what you see on the screen are not scratches, but dust on top of the cover.
P.14
P.15
You can see the "haze" from the protector in P.15. It is exaggerated in the lighting. It is not at all visible when the phone is in use.
And some shots of the phone in action:
P.16
P.17
The touch screen did not suffer any damage or degradation in performance as a result of the polishing or the application of the screen protector.

I did not realize gorrila glass was easily scratchable. I see youtube videos of people taking nails and screws to it without a single scratch but after this Im a bit worried not using a SP. Thanks for the info though.
No clue how you got those scratches, but thank you for a VERY good post. I'll be sure and add this to the sticky a bit later. Great job with the post man, really helpful.
Still confused about the scratches... I ALWAYS carried my plastic swipe card with my phone, no issues... ever.
The only way I can see that happening is that I got some grit in-between the phone and the card, and it rubbed. After my experience with the sandpaper, I can safely say that there is no possible way that plastic could do that. Still there's no way around it, I put the phone in my pocket with the card, and 20 minutes later, scratches.
I was at a natural park, so it's very possible that some sand, or something a bit harder than you would normally encounter got in there, but sooner or later it certainly can happen.
scratch repair
Nasty!
This is the first phone I've ever used a screen protector for and I put it on at the store when I unboxed the phone. It wasn't a day before I dropped the phone and was so very glad I'd put the protector on.
Regarding the buffing, I've had good luck getting scratches off the iPod touch with good old fashioned toothpaste and a finger. I'd be terrified to take a wheel to it with the amount of heat those things can generate.
Thanks for posting!
Yes the heat is a good point. I had to be careful about that. I'll note that in the OP.
Tooth paste and a finger will not touch this glass. It's just far, far too hard.

It all depends on how it happens.
As you can see from the OPs suffering, he had a hard time with sandpaper! Yet, something that happened to be in his pocket scratched it up something fierce.
Moral of the story, get a screen protector, you'll be the 1/10000 that manages to scratch his screen if you don't.
Also, OP...THANK YOU very much for this post. I might have to do this for my girlfriend, she scratched her screen on her earrings before we got the screen protector put on.
I have a nice vibrant with dead pixels.. Wasn't me to do a scratch test? I've taken a key and a screw to the corner already.. I used alot of force and it can only be seen with oil from my fingers.. But after cleaning the screen with a cloth they disappear.. I have no problem messing up this screen if y'all want me too...

I've heard people reference this Asian video saying "wow no scratches,"
I guess people aren't looking closely, you clearly DO see scratches.
http://www.youtube.com/watch?v=6xASJobjD68
First scratch evident at 1:47-150, you have to pause at the right angle!
more scratches evident at 1:54
More scratches evident 3:05
And again at 3:10-3:11
And of course, friends of mine with the Galaxy S unprotected, and of course, scratches!
Protect that screen! Interesting thread through.
That's why I still have the screen protector on when there were so many people saying that it is scratches proved blablabla...
I'll pay the $160 before I put on a screen protector. Actually, I *did* pay the $160 already. Ha ha. I dropped my Vibrant on cement about two days after owning it and massively cracked the screen. If I get a light scratch then I can live with it but if it's like yours looked in the original post, I would pay the $160. Meanwhile I keep it in a pouch when it's in my pocket.
Excellent post
Excellent post
Not sure how the scratches were so deep unusual. Anyway, if people are interested in this kind of fix you can go to a gem stone supply and get the polishing compounds that are graduated (fine to finest) and use these. The fine will cut more and take the large defects and then move to finer and then finer. Remember the heat issue always check the surface and make sure it never gets too hot to touch.
Excellent post
I believe Ghost Armor should be a top priority for us Vibrant owners. I am a Ghost Armor employee. Do your research. It would of protected your phone from ever getting any scratches. Plus it also helps from impacts. Dropped my vibrant face down on tile and its still spotless. $25 for a full body wrap is a great deal.. especially with a lifetime warranty! PM me for more details.

The girlfriend & I have both done that WITHOUT ghost armor and had no scratches.
And how is a thin piece of plastic going to help with impacts? It might help with the side effects of impacts (you know getting scratched while hitting the ground), but it's not going to be enough to cushion the impact itself any noticeable amount.
You might want to run some things by your legal dept. before you start acting as spokesman.
I've also read that while the GA is great as a SP, as a full body cover, it seems to peel after a few months of normal use.
Wow, very nice work man. No way would I have had the patience for that

I love how you call it a thin piece of plastic. It's actually polyurethane, which is a pretty sturdy material. Please dont tell me you believe a hard case is necessary for your phone.. Please amuse me..
I am a sales person that stands by my product.
It will peel depending on your usage of the phone.. Thats why we offer a lifetime warranty..
Any more questions?

I did this as soon as the Ghost Armor kiosk at my mall got the Vibrant protector. It took them almost 2 weeks after I got my Vibrant for them to get it in. I had to go naked for TWO WHOLE WEEKS.
Back when I first got my iPhone (3 years ago) I got the InvisibleShield, but I prefer Ghost Armor, because firstly, it doesn't get that yellow discoloration, and secondly, with the kiosk at the mall, I don't have to worry about improper installation. The top part of my Vibrant got all messed up (some lint got in there and then it spread) and the guy at the Ghost Armor kiosk just replaced it for free! (Of course, there'd be an installation fee if I wanted to replace the whole screen part or the full body, but still!) My friend also got Ghost Armor on his iPhone 3G and it saved his screen from breaking into a million pieces when he dropped it on a rock (It still cracked though.)
If you don't want to take it from an employee, take it from a satisfied customer. Encase your Vibrant in Ghost Armor ASAP!
Take 2: I'll try to play nice....Usually I would have just deleted the thread....however, I'm trying to change....so....I'll take the time to dumb this down for those who aren't quick enough to follow. Open wide, here comes the spoon feeding!
What:
I'm trying to find if there's any interest in getting a (cheap <$10) replacement for the glass back of the N4. Right now...it's just an idea. There might not actually be anything that's thin enough to be used as an alternative. However...it might be possible.
Why:
Why not?...but seriously...once the glass back shatters, it's unsightly for one. It (in my case) doesn't leave a decent enough surface for a DBrands skin (mine looks lumpy as **** because of the bits of glass). And it leads to other possibilities...for example, you can get a clear acrylic/polycarb piece and etch it? Color it? What ever you want to do to make it yours...
How:
I'm not fully sure yet, I know there's a few companies that will cut acrylic however you want, they charge per sheet, and per cut...if a cut/corner is rounded they charge per corner/rounding, etc...so that's all going to have to be worked out. Also, there is differences between the types of attenuation of different materials...for example after I put Poly Carb in the title...I found it has worse effects on RF than Acrylic/Plexi. Along with that, there are downsides of each alternative...some are more impact resistant but easier to scratch....some the opposite.
Please don't come into this thread and post about how it's not possible, how it can't be done, how it's a dumb idea because of one reason or another. It's in fact...POSSIBLE, it CAN be done, and it's NOT a dumb idea...(according to the poll and the post on Reddit anyhow). I've been dealing with these devices for almost 2 decades...I know what I'm talking about when it comes to this sort of thing.
Now, for those who will start crying about how there's antennas and NFC and "other stuff" attached to the back...refer to the last sentence of the previous paragraph....THEN look at the pictures below, the first of which shows there is NOTHING other than the NFC antenna.....which picture 2 shows is removable from the glass....Thanks for reading...if you even got this far...
Edit: That's actually not the NFC antenna, it's actually the charging coil.

Without a doubt. AS LONG AS... Incredibly detailed instructions are included with the purchase as far as how to separate the phone... Although I guess anyone can go to iFixIt or something... But it would also have to retain NFC and wireless charging...
+1 on the soft touch BTW...
as we start shattering the back glass this ideal will no longer be thought of as anything but the greatest... go for it!
just wondering, will it effect the wireless charging?

That's a great question...though I can't imagine it actually affecting it, I'd have to test it (if this thing ever goes forward)...
Edit: according to this site it's less dense therefore less obstructive.
Alright, so I've got a place here in Chicago that does this sort of thing, it's just the matter of finding out if they can make the cuts for the speaker...and I'm unsure if the LED lens is a part of the back glass or not....
Gonna need a cover for the camera built in too

That's actually the NFC antenna AND the wireless charging coil (NFC antenna is the outer coil, charging is the inner coil).
No one said in the other thread that they couldn't be separated, it's that the antenna, coil, connectors, plastic housing, camera cover, etc. are all glued to the glass. Separating them for a tear down article is one thing, separating them to later reglue them to a polycarbonate cover is quite another. It's not impossible, but it's a lot more work than most people are going to be willing to do (unless they've already broken the glass and their only other choice is a $$$ replacement).
As an optometrist, I'm curious about something....
Polycarbonate would be a great material for impact/breakage resistance, nothing better actually.
But, non-scratch resistant coated polycarbonate will scratch almost with a fingernail. Is it easy to get scratch resistant coated poly for this type of stuff?
would you just glue it on? or how would it be applied and yet friendly with the antennas in the back, gsm,wifi etc. i would like a rubber backing so i can be rough on it and something that will absorb the heat more
FYI- I just measured the glass and it looks like it's 0.5mm thick.
Removal of the glass isn't too hard, even though it has adhesive all over it (on second thought, maybe it's just around the perimeter and in patches in the middle).
As I had mentioned before, the thing to be careful about is removing the copper shielding from over the NFC+Qi coils. The copper tape is really thin so it tears easily, and if you do get it off, it'll curl up and stick to itself (luckily though, it's usually not and adhesive-to-adhesive stick, so it's possible to unroll it). I've been able to get a couple of removals and reapplications out of both the copper tape and the coils, but the adhesive on the coils is wearing off, so I probably won't be able to do remove and reapply (using the same adhesive) many more times.
Removing the glass from that point is relatively easy, done by pushing out on the glass through the speaker and coil holes in the plastic housing. The problem is that the adhesive around the perimeter sticks better to the plastic case, and cleanup is a bit of a pain.
The adhesive actually sticks pretty well to the paint on the back of the glass, however, the problem is that the paint isn't so good sticking to the glass, so on the back plastic, there will be a ring of adhesive with paint on it and the glass will have a relatively bare spot around its perimeter, say maybe 1mm wide. But I guess that's not that big of a deal if you're just planning on replacing the back glass.
With the LED lens separate from the back glass, adhered to the plastic case, you don't have to worry about removing that.
Certainly, if my back glass breaks, I'll be replacing it with plastic. I'd probably use PETG instead of polycarbonate since PC is harder to lasercut and yellows along the cut, though for 0.5mm thickness, it might not be that bad, and you could always CNC mill the PC instead. Finally, I'm not sure if may places will laser cut PC. Acrylic might be nice- it's really easy to laser cut and relatively scratch resistant, but I'm not too sure how easy it is to find in that thickness.
As I see it, you'll want not only a polycarbonate/plastic back, but also the adhesive around the perimeter and possibly some patches of adhesive in the middle. The polycarbonate will probably need to be die cut or something, but you can get the adhesive lasercut. Certainly factor that into the replacement kit BOM (Bill Of Materials) and also price.
If I were to assemble it- and what I did for my glass back- is/was to cut the adhesive large, apply it to the glass, then use scissors or a craft knife (X-acto) to cut the excess adhesive from around the perimeter of the glass, then apply the glass to the back housing. After that, then you can reapply the NFC+Qi coils, the camera gasket and put the speaker grille into place. You can probably get the adhesive preapplied to the plastic, however, that increases costs.
edit: maybe acrylic isn't that scratch resistant.
Yes do this!

Now THAT is a response. That's what I was looking for. Thanks a LOT!
Now as far as what I've found out about potential materials:
Acrylic has the...better? combination of factors (surface hardness, durability, and RF attenuation) that make it the most suitable however, if the glass is indeed .5 mm thick, it's not the best of options...since most places I've reached out to only have/go down to 1/32" or 0.7938 mm.
PC we all know is the best as far as durability however with that...the surface hardness is not ideal unless it's going to have a skin on it to begin with...Oh and RF attenuation is definitely higher than with acrylic/plexi...
PETG I never knew about to be honest (this started out as an idea) but from the little that I did read into...It's similar to PC it seems to me...though I literally spent all of 3 minutes trying to find out about it...
This site has some great info related to attenuation which, with me being a HAM, actually matters. Knowing how ****ty the design of the mobile device antenna is from the get go (due to obvious limitations)...
Edit: After reaching out to a few fellow hams, the RF attenuation isn't even something to worry about at our frequencies...The loss (if it's even measurable) would be so low that it's not even worth considering.
Very very interested in this. Though my back is protected in an Acase dual layer, I don't rule out one day tragedy striking as is seemingly common with our device.

Anyway I ordered the front assembly for $90 (with frame). For the back, I will first use a cover. Then I will look at alternative, but replacing glass with glass no way, it would break again. It was looking good though, before it broke.
Case or no case?
Never been for the case. I would always opt for a 9H tempered glass. I've bought both the front and back Nilkin 9H tempered glass and it's been working pretty well for these two months. I recently dropped my z3 on the floor. No damage but the tempered glass did crack. If you don't mind taking away from the beauty of the phone, I would definitely recommend a case. I bought the Ringke clear case at first but it just made the phone look bulkier.
I have a Ringke, but like to use my phone bare, also have front/back glass protectors.
However in corner impacts the glass protectors will be useless as one person already found out, though he did it on purpose to show off .
I have a tempered glass 9H screen protector on the front and when I don't use the phone it lives in a slip case with a pull tab. When I do use it it takes all of a second or two to get it out and it's naked in my hands. I can't stand an ugly case that wraps around a phone. Why would anybody obscure the beautiful design of an item with a case? It makes no sense... Although like I say my compromise is a slip case.
My phone is in absolute mint condition with not a single fine scratch on the back yet so I reckon my system works pretty well for me.

No case here either. I just use a lanyard ring. It helps with holding/using the phone with 1 hand. Will probably get some cheap screen protector though because the phone is so slippery.
The phone design is too sexy, why cover it up?
Just a belt case when at work
I don't use a case, but I didn't vote because I don't think it's tough enough. I just don't like cases, they add bulk and ruin the design.
I do use a lanyard/strap though because the entire phone is slippery. I put a Xtremeguard back protector to make it less slippery, but the sides are still slippery as hell. I'm really considering using Plasti Dip on the sides.

Jokes aside, I agree with Shilent. No case or front screen protectors for me--it ruins the design and full experience of the phone. The only thing I would add is a protective sticker on the back so it doesn't slide on the table.
I voted no case, but don't think it would survive a drop....
Lol, Hanime.
Case really does ruin the phone, I only use the Ringke outside, that too occasionaly. After seeing Gorilla Glass 4 adverts by Corning showing 2x increase in impact resistance, espescially rough surfaces. I wish it had released in time for this phone.
Mine is naked now. My cruzerlite case lasted 3 days.

You should consider a tempered glass screen protector if you hate stickers. It's incomparable to the old idea of a plastic film protector.
It's 100% invisible and makes the screen look unbelievably beautiful while offering great protection if u should drop it.

How does something invisible make something look beautiful?
It won't add much protection to dropping your phone either, especially if it lands on the side of the device.
Carrying it naked absolutely out of the question for me.
I sell my phones every 2 months. Resale value is paramount, so I wont risk a small scratch or dent.
Yes the phone's design is sexy. However IMHO, using casemate tough case somehow adds to its beauty while adding more grip to it.
i'm using case right now, but a super thin 0.33mm clear TPU one . just for that extra safety feel
No case, because I know what the phone looks like, and I couldn't care less what anyone else thinks it looks like, and I want some protection against both drops and scratching from being in a pocket/general wear and tear over the 2 or 3 years I'm going to have it.
No case here! Just using a glass protector on the front and naked on the back because I couldn't find any.
I just hate the fact that my glass protector has cut outs for the sensors, doesn't fully cover around the speakers and has a cut out for the NOTIFICATION LIGHT. Seriously, wtf
Ok, now I just have a glass screen protector on the back and nothing on the front. I've been getting some scratches on back, so I need something on it.

God what a stupid reply. Firstly, because it's just another layer of glass it's pretty much invisible - but because it's glossy and of a high quality it compliments the resolution of the screen and makes it look really good.
Just look up some videos on YouTube where they are reviewed or something.
Also it protects the screen against drops - in almost every drop the screen protector shatters leaving the screen in mint condition. There are even a few videos where they are hit with a hammer and it's the screen protector that shatters, not the screen.
Erica Griffin did the same test. But for now, look at this:

I'm sorry, I was unware the glass on the front of our screen wasn't glossy and of high quality to begin with. Silly me.
I'm going to go buy a glass screen protector now so I can have beautiful display now.
Never did I say the glass screen protectors were nice, I use them myself.
If you read my post carefully I specifically said it's not going to protect it from a side impact, which it's not.
I swear, people get more retarded everyday.

I have an Ultimate Shield glass protector and it has only three cut outs... The two speakers (onbiously) and the sensor just to the left of the Sony logo. Everything else including camera and notification light works through the protector. This one is 9H hardness. Which one do you have then?

I have owned the phone for 2 weeks and have some really horrible scratches on the screen already. I really don't feel the screen should scratch this easily as I have never experienced this with a phone before.
The phone has been in a case since day 1 that elevates it if placed face down. Additionally I have not dropped the phone at all. The phone always goes straight to my pocket by itself facing my leg. I checked for dirt in my pockets and there is none that I can ever feel. I really don't understand how this is happening. The scratches are extremely noticeable in direct light and do not resemble microscratches, but thick scratches. I feel as if this glass is defective or something with how quickly and seemingly easily it has scratched.
Is there anything I can do to exchange the phone, buff the scratches, or get rid of them?
Here are some photos of the scratches, granted the camera doesnt really capture it as well.

Yes it is not normal at all, did you put the phone in the sand or something like that, because i don't know if Samsung cover this damage. If it was on the phone at the opening of the box, the warranty can be used i think.

It was not on the phone when opening the box and no it has not shown any signs of sand on it. Just scratches appearing.
The scratches cannot appears like that, something has scratched your phone, I have it for 1 month and there is ont a single scratch on the screen, it's really strange...

I always got the latest flagship phone from Samsung, Apple, and Google. I am not using any screen protector, just a very thin back cases at 0.35mm. Micro scratches are present in all devices all around the screen but barely noticeable even in bright lighting like on mornings outdoor. Only visible at certain lighting and when you really looked for those scratches. If you do not want those micro scratches or glass scratches, then use a screen protector. Phone screens are mostly glass and not pure sapphires to not be scratched (except using diamonds). There is no way for phones with glass screens to be at 100% smoothness for a long time without using a screen protector unless you are not using it. Also, you won't use your phone forever anyway. You'll eventually upgrade after let's say 2 years maybe so why not just use it as it is.

Well i don't think so. I have used almost all flagships from apple, samsung, and nexus phones as my daily driver and It all got micro scratches after 2-3days of using it without a screen protector. I am careful with using my phone and not putting it on my bag without a towel or soft cloth covering the phone and when putting it on my pocket sometimes, i am making sure it's clean and nothing on it, just the phone.

We can agree to disagree. I also don't think you should judge anybody on this forum just by nature of their post - I'm sure he and I are just as careful as you are but that doesn't mean we are in any way negligent for the scratches that seem to have appeared on our phones versus you

What i was saying is that, it's not that we are not careful or it's not that the phone is bad. It's just the way it is. Use a screen protector and your phone screen will be smooth. Don't use a screen protector and your phone screen will eventually have scratches. Not because you are not careful but that's just how it is. It's not made to be scratch proof, just scratch resistant.

That I completely agree with you although I must tell you several screen protectors especially for the curved glass are nowhere near as smooth as the original glass on the phone itself and you can include the film protectors for sure - thank you for keeping it civil.

There is actually, the official screen protector from samsung. Not a tempered glass, but a curved film that will fit up to the edges of the phone. It does not involve wet aplplication btw, just apply as normal screen protector. Also, i have seen one film screen protector that sticks up to the back of the phone (not the whole back) and it's definitely not gonna peel off as the screen protector does not end on the edges, but on the back which is quite clever i think so that the protector will really be protected up to its edges and it will not peel off at the same time. It's a very thin film so cases will still fit.

I´ve never had a scratch with iphones before, for years, obviously not counting when my iphone 5s fell to the floor
It scratches at level 6 on the hardness scale which is pretty typical of high-end smartphones. Saying "my previous phones never scratched" is like saying "I never had an accident in my previous cars" after having an accident in your current one and then blaming the manufacturer. .

]I purchased this glass screen protector back when the S9 Plus was originally released and it worked great. I loved it. BUT, I had some issues with Dropped Calls on my S9 Plus and had to return the phone. I just received the replacement phone and I had no trouble making the decision to getting the OTAO glass screen protector again.
I was very surprised and pleased to discover that they had made some additional improvements to what already was an awesome glass screen protector. From what I understand, they added additional adhesvive around the edges. NO this is not a full screen adhesive, but I found that It really doesn't need full screen adhesive to be effective. I have installed this screen protector and use a case (Ringke Fushion) and it works GREAT.
No loss in touch responsiveness - no issues at all - They do inlcude a plastic guide that helps to facilitate proper installation and I have found that the plastic guides really do help to insure the screen protector is placed properly - perfectly centered on the screen.
So I give my highest reccomendations for the OTAO Glass Screen Protector - NEW AND IMPROVED.

It has adhesive on the edges only - but it holds very well - No lift at all from the case I am using and the case rides up pretty high on the corners and the edges and doesn't cause any issues at all. The glass seems to be full coverage from what I can tell. It is a very good screen protector..
How is touch sensitivity with this protector? Do you need to increased touch sensitivity in the settings to use it well?
Found this one on amazon... https://www.amazon.com/gp/aw/d/B07B...l+adhesive&dpPl=1&dpID=41RhK1whyLL&ref=plSrch
If it's not full adhesive don't waste your money. Honestly people, I wasted so much money trying to find one for the S7 EDGE two years ago.

Touch sensitivity is great and no, I did not change the touch sensitivity frm whatever the default settings were. It is now day three - I have the S9 Plus in a Case (RIngke Crystal Fusion) and I have had ZERO problems with the OTAO Glass Screen Protector.
Honestly, I don't have a problem with glass screen protectors that don't offer full adhesives on the glass. The manufacturers like OTAO have learned to put the right amount of adhesive around the edges (there is more now than that they used to put on them a long time ago) and with the plastic GUIDE they provide to help you install the glass properly, there are considerably less issues than way back when curved screens were first out.
the key to glass screen protectors working on curved screens is proper placement. The screen protector has to be exactly centered on the screen. if it is too far to one side or another (even by only a little) that is when you have issues with the case pushing up on the screen or poor responsiveness when typing or whatever.
PLACEMENT - it is absolutely critical. That's why having the plastic guide included with the OTAO (and other similar glass screen protectors) helps to insure a good installation and quality protection that is really affordable.
Guys I bought the same screen protector. Here's some photos in the Poetic Revolution case. I'll add my thoughts. The screen protector is very nice. The tray guard made it pretty easy to install. Its not a full adhesive protector so the glue is around the sides. Make sure when installing you press hard around all the black edges to make it seal better. Its a dot matrix protector but the dots aren't easily seen so it must be a newer type. Make sure to turn up the screen sensitivity for screen protectors in the settings and it makes it like its not even there. The edges really smooth right over the sides. The one I had on my pixel 2 xl didn't do this and had sharper edges and made dust stick to them. This one is so much better. It also fits perfectly inside the Poetic Revolution case with the built-in protector popped out.

The ESR I have is nice, but the glue strip can be seen on the sides. Although it is "clear", you can still see it and touch sensitivity sucks even with the enhanced option on. I will return it and try another one.

You are entitled to your opinion - frankly I have found that many edge only screen protectors work really well. It's all about getting it installed properly - I don't see glue on the edges of the one I am using - and don't get dust there either. I haven't changed settings at all and touch sensitivity and responsiveness is great. Absolutely no complaints.
(now I have tried some edge only protectors that sucked - they click when you type on the keyboard or wouldn't let you type the letters on the far left or right) but when the manufacturers started including guides for installation and increased the glue around the edges, the quality of many of them ended up getting much better.

I installed a Glass Screen Protector from OTAO as soon as my S9 Plus arrived today and I have to say I am extremely impressed with the fit and quality of this glass screen protector.
It is the XLAMBO version - extra thick glass that essentially makes it much harder to crack when you drop your phone. Installation was very easy with the included plastic guide and I lose absolutely no responsiveness at all - the screen works as well as it did before I installed the Otao Glass Screen protector.
I also installed a case with this Screen Protector and there is zero interference from the case at all, it doesn't raise the glass up at the corners or sides like some other glass screen protectors have had problems with. and the price was very reasonable - under $12 bucks. Of course they include a full warranty so you don't have to worry if the glass does crack while protecting your phone.
The glass screen protector comes down very close to the sides of the phone, giving you full coverage - with a case on, it seems and feels like there is no space at all, all the way around the phone, top, bottom, sides and corners.
I am using the RINGKE Clear Fusion Case but I am confident it will work a bunch of other cases as well
