[Galaxy S II Accessories] Ping69:
well do u have any brand in mind? I believe sgp is the only brand that has oleo type for sale in my country :o
[Galaxy S II Accessories] rakeshishere:
You have ebay to order it from any part of the world.

There are other brands who claim to be oil resistant and oleopohic but sgp ultra oleopohic series has some really good reviews online with combination of good screen clarity.

The cheapest I could find is 13.5USD and I remember buying a Nokia basic phone for that price which is equivalent to cost of screen guard for the SGS2 :D
[Galaxy S II Accessories] yoyogu:
I've personally always used a SGP screen protector. You never know!
[Galaxy S II Accessories] lambstone:
Yes it will be crystal clear. Now for me, I've noticed that it becomes noticeably less "oil resistant" in a 2-3 months, so I suggest that you get the Ultra Crystal instead as it is 33.3% more scratch resistant according to the technical specs.

If you were going to fork out so much for a screen protector, I suggest, glass protectors. They are really the best there is. It's pretty much "scratch-proof", I've used knives and pen knives on it and its fine. The feel of it is as though you weren't using one.
[Galaxy S II Accessories] 23732:
I use a screen protector because I am overprotective and I am used to always have one on. I also like the fell to have one on.
[Galaxy S II Accessories] MissClueless:
Maybe i´m too cautious at all

but I prefer to use a protector

than to be upset

when i gonna find the first scratches

:cool:
[Galaxy S II Accessories] S0und_:
Currently i'm using Steinheil Crystal Clear, but after 1,5year of usage i'm a bit sick of the constant smudged screen. So my question is, a oleophobic screenprotector can reduce this greatly? I'm not exptecting to dissappear completely.

http://i.imgur.com/RCler.jpg
[Galaxy S II Accessories] haieb:
yeah i used the steinheil ultra chrystal protector. It is really oleophobic! I used it for about 1 year and removed it last week. I hate the smudge and the protector did a great job. But i must admit that the screen ist sharper and brighter without the protector.

Pro:

-No fingerprints.

-matt: better for outside.

-Good protection

Con:

-the screen looses brightness and isn´t that sharp(really maginal).
[Galaxy S II Accessories] S0und_:
so it's worth it?
[Galaxy S II Accessories] bihslk:
Removed mine for about 1 month ago. Still no scratches at all. Wearing phone in my pocket...
[Galaxy S II Accessories] dinci5:
I always use a screenprotector.

Bought 20 of them for 5USD on ebay. lol

You get used to it... and I know for sure that the screen is safe
[Galaxy S II Accessories] Abaddon:
using mine without one for 4 mos. still no scratchess. always on my pocket :)
[Galaxy S II Accessories] dinci5:
OK, I'm really confused...

Is the screen really that good?

To be honest I'm afraid of using it without a screenprotector.
[Galaxy S II Accessories] Beowulf_pt:
I'm one of those that never uses a screen protector.

I've had my i9100 for almost 1.5 years now and the screen has no scratches at all, at least nothing you can see easily without a magnifier and close look.

I dropped the phone once and it landed on one of the corners, slightly chipping off some varnish off the plastic case, but the screen itself is still immaculate.

All I do is have some basic care: I never carry the phone in pockets along with coins or keys and I don't put it in bags where metallic objects are. Other than that, the glass seems strong enough and I don't have to deal with pestering screen protectors (IMHO they all suck, albeit to varying degrees). The only extra I bought for it (and best investment by far) was just an extended 2700 mAh battery and that was it.

TL;DR If you are careful you don't need a case or screen protector and by the time your phone is damaged, it will be worth so little it doesn't really matter anymore.
[Galaxy S II Accessories] g.woodward:
I use a screen protector just in case. I'm hoping to sell my SGS2 on when I upgrade. Since I've had it (nearly 18 months) I've had a Folix screen protector via Amazon on my phone. It had the best ratings of any I found and it covers more of the screen than any others I've seen (doesn't just miss the ear piece and front camera it has perfectly sized holes for them and continues along the top).
[Galaxy S II Accessories] :
I have s2 for about two weeks and no scratches, i tried to scratch it with knife but without succes, super amoled and gorilla are amazing

(sorry for bad english)
[Galaxy S II Accessories] NanoSurfer:
I use a case (case-mate) plus screen protector (body-glove matte finish thingy). It certainly takes away from the true brilliance of the SUPERAMOLED display but there's no way in hell I will have it any differently!! I can live with a scratched screen protector, but not a scratched screen. That's just me though, I love my tech too much. Different strokes for different folks
[Galaxy S II Accessories] FrankStealth:
I never worry about scratching a gorilla glass... And i hate the idea of a protective screen or cases, it's just ugly, but:

Now here"s my INTERESTING screen problem (and were not talking about the burn-ins that i have)... I scrolled so much, that the texture of the glass changed it's gind of grainy now. It's just a small portion, fingerprint size (my thumb). You cant see it, but you can feel it. I find it funny.

I'm using Proporta screen protector and SGP Ultra Capsule since I got my phone and it's still in the same condition as day 1, even with days at the beach and working outdoors. I would dread to think of having my phone without at least the screen protection, it certainly wouldn't be as immaculate as it is!
[Galaxy S II Accessories] FrankStealth:
aa
[Galaxy S II Accessories] HippoLOL:
I keep mine all nude. Been going great. Of course you must be careful you don't drop it.
[Galaxy S II Accessories] SquEebEr:
I ran over my old SGS1 with my car. Screen face down on asphalt, phone is OtterBox. My screen protector at the time was an iShieldz. Panic struck my soul the moment I saw the tire track streaking down the back of my phone. When I turned it over i saw dents all over the screen but no cracks. I removed the phone from otterbox, yanked screen protector and absolutely NO marks on screen at all. Sure, it there was a rock under it, I would have been replacing glass. But I assure you, the protector I was using definitely saved it. I sold the phone. lol
[Galaxy S II Accessories] lucsbran:
I use smartphones for many years now and always use a screenprotector. To bad I do not find an "invisable" for my S2. Only clear and those are like a mirror in daylight (sun)
[Galaxy S II Accessories] praktical:
I've always had a screen protector on all my phones. Better to have it and want it than to learn the hard way from not having it.
[Galaxy S II Accessories] erni313:
Hi , I have been using my SGS2 for a year now . In the begging I didn't use any case , no screen protector ever . I dropped it a lot of times but once it felt so badly that I thought that it needs a case asap . I got a screen protector and my phone felt a little bigger ,

One day I dropped super glue all over my screen , It was terrible , I tried to wash it with alcool , nothing . I tried it like 5 times , Then I started to scratch the screen with keys to remove the glue , in the begging I was very cautious then when i realized that the screen was not scratching at all i cleaned it with my keys .

So the screen protector is useless and ugly , really . What's the purpose of buying a beautiful phone then after buying these accessories it becomes ugly ? My phone is more than a year older now I don't have the case at all , and only some scratches in the metallic frame .but it's fine .SGS2 is slim and beautiful
[Galaxy S II Accessories] asprillon:
no screen protector and no scratch ;)
[Galaxy S II Accessories] rakeshishere:
Give it to me :D
[Galaxy S II Accessories] FrankStealth:
No, dont give it to him, force him to live in the future too. This is not the 90's/00 anymore!

Man do you guys know what Gorilla Glass is? Watch Youtube videos on it. Scratch tests show you can stab phones with a knife and nothing happens!

Case closed.

LoL you are so wrong...

The s2 from my gf is scratched a little and my s2 looks horrible after 6 month.

if you want to, i can try to take some pics.

but yes gorilla glas can get scratches...
[Galaxy S II Accessories] rakeshishere:
My friend's HTC EVO 3D which has gorilla glass is also scratched after a year of use. He doesn't believe in using a screen guard or case as such on a phone. He's quite careful about the phone but I laugh at him seeing his screen been scratched.

I don't know how people claim not to have a single scratch on a phone.
[Galaxy S II Accessories] FrankStealth:
Some galaxy s2 devices like skyrocket do not feature gorilla glass.

Did your HTC friend remove the factory foil off his phone xD?

Could you please let us know HOW TO scratch a gorilla glass? Maybe with keys... at 400°C or outstanding pressure?

And nowadays theres also corning gorilla glass 2, 20% thinner which is (or should be) the new standard.

[Galaxy S II Accessories] Pfeffernuss:
How about one measly little particle of good old ordinary sand? It will completely f*** up your display as it is much much harder than the Gorilla glass panel.

And no, there is no way to be 100% certain that there isn't a single grain of sand in your pockets.
[Galaxy S II Accessories] carlocarrera:
Its the normal s2 with gorilla Glas...

Trust me its no problem to scratch it.

But hey do whatever u want, i dont care anyway so....

Here we go: http://www.youtube.com/watch?v=kKPg6tPCxHM

Now u can start crying...and real sand is even worse !

quote from my link: All it would﻿ take is for a single grain of salt to be left under your finger after eating at mcdonalds.

think about that, and even salt would NOT hurt ur screen sand does.
[Galaxy S II Accessories] FrankStealth:
xD i dont care either. Apparently in all the one and a half years i didnt have sand in my pockets.

Okay so your basically saying that sand aka SiO2 will scratch gorlilla glass aka alkali-alumosilicate MAlxSixOx Makes sense.

Metal doesnt harm it, but sand shure does...

Did we nail it already xD?

================

GT-i9100 ICS 4.0.3
[Galaxy S II Accessories] carlocarrera:
omg...

so u REALLY think metal is harder then sand ? really ?

of course sand can harm your gorilla glas, glas is made out of what ? right...

[Galaxy S II Accessories] Dimatchka:
Quartz in sand is what really damages your display because it is harder then the gorilla glass. not because like damages like. Fyi diamond is a rock and its hard then metal. In fact is the hardest rock. Ignore the thanks I gave you out was an accident with tapatalk

Sent from my SGH-I777
[Galaxy S II Accessories] carlocarrera:
i will Ignore the thx and you, how do u like that ?
[Galaxy S II Accessories] FrankStealth:
I am aware of the Mohs scale www.en.wikipedia.org/wiki/Mohs_scale but you see i wouldnt have guessed that alkali-aluminosilicate gorilla glass was under 7 which is quarz aka sand (main component of normal glass)... the video proved it for me.

* and diamond is not a rock, its a mineral.

Better also keep our phones away from those darn diamond rings as well xD

[Revised.... Read on]

================

GT-i9100 ICS 4.0.3
[Galaxy S II Accessories] FrankStealth:
Cant get this out of my head... :D

Well i'll be... sand paper is not necesserally SiO2. It says here that quartz is used for wood polishing (weak)... www.topics.info.com/how-is-sandpaper-made_2792 Other sandpaper materials are aluminium oxide or silicon carbide.

So for that video we don't know what that guys sandpaper is made of...

I still couldn't find proof of actual sand, scratching a gorilla glass. What i did find is this: www.chemistry.about.com/od/howthingswork/f/What-is-Gorilla-Glass.htm It says here that gorilla glass is 9 on mohs scale... That would mean that ordinary quartz doesnt scratch it.

I'll believe it, when i actually see it. It would be logical though: if sand scratched gorilla glass, then we wouldnt use gorilla glass in the first place, we would use ordinary glass.

Also another question arises in my head about the mohs scale: is it really like that, that you can make a simple scale of what scratches what? Isnt it more complicated? Like for example x scratches y, y scratches z, but z scratches x... like in a circle, or triangle, whatever.

So the question remains: wheres proof of ordinary sand, scratching gorilla glass?

Or any other ideas of non-exotic materials that scratched your phones? Cause i sure dont have any scratch!

i use sandpaper insted of a microfibre cleaning cloth because im hench as f*ck
[Galaxy S II Accessories] prnvp23:
Well better to be safe than sorry as I learnt the hard way, my S2 is about 6 months old now and I have quite a few scratches, the consolation being that the scratches are small, very faint and can be seen from only certain angles or direct sunlight but they are there nonetheless and make me wish I'd spent a little money on a screen protector. The 1st few scratches appeared after a trip to the beach so yeah, Gorilla Glass is scratch proof but not 100% scratch resistant
[Galaxy S II Accessories] carlocarrera:
Nothing more to say i guess...
[Galaxy S II Accessories] FrankStealth:
One more thing and i'm done with this! I found out how it is now, according to:

[1] http://chemistry.about.com/od/howthingswork/f/What-Is-Gorilla-Glass.htm

[2] http://en.m.wikipedia.org/wiki/Mohs_scale_of_mineral_hardness

[3] http://en.m.wikipedia.org/wiki/Sand

Mohs scale:

[1]

Gorilla Glass - 9

[2]

Random metals - 0.2 to 8

Tungsten - 9 to? 9.5

Titanium - 9.5 to? 10

Diamond - 10

Quartz (SiO2) - 7

[3]

SAND (composition: mainly SiO2 + other rocks and minerals, location dependent) - 7 to 10!

CHEERS!

So in CONCLUSION: if you happen to rub sand, also containing for example diamond (extreme case) on your phone, it will scratch.

I also found this: "Misconceptions about Gorilla Glass" on XDA http://xdaforums.com/showthread.php?t=1866049 He sais that gorilla glass is 7, but i found out it is 9 [1].

He talked about another aspect that he sais is on cornings own website, that what actually scratches on a gorilla glass is the oleophobic coating. Oleophobic coating? Maaan my phone always looks like a friteuse! Maybe screen protectors do better... Also maybe thats why some sources say its a 7.

My conclusion: i wouldnt use a screen protector to cover my good looking screen. Im always pretty careful with it, not dropping it on floor or concrete. I very rarely to never have dirt in my pockets. Keys, lighters and such wont hurt it. So who cares about protectors? I dont.

Since im always on the run and more than 8hours of the day on a motorbike, i prefer to use screen protector even if m sure that is not needed.

Better safe than sorry for my case.
[Galaxy S II Accessories] laui888:
Might just as well remove my protector!

I have a screen protector on my sgs2 since day one...however, recently a thought has across my mind... I think I might just remove it out of curiosity. I dont think it would make any difference. O well, who knows what could happen. :rolleyes:
[Galaxy S II Accessories] Pfeffernuss:
It will...

...make you feel sorry. It will scratch. Don't believe the hype/marketing nonsense.
[Galaxy S II Accessories] sepu79:
well..

i was playing soccer with my kid few weeks ago and i dropped my s2 in the ground,it slides in ground like a one meter and i did get a couple of small scratches.BUT i dont care,it is just a phone.
[Galaxy S II Accessories] lesp4ul:
Yeah sands and other mineral materials definitely will scratch gorila, you proved it.
[Galaxy S II Accessories] serhat737:
Gorilla glass is really strong, this is my second s2 and i not use a protector, and still like first day clean. But shining metals on korners is so bad
[Galaxy S II Accessories] Reno29:
The first day when I have the s2 in my hands think the same, gorilla glass is unscratchable, but it's not, after a week without a screen protector, I start to see little scratch in the middle of the screen, and it's more visible in brightness areas.

[Galaxy S II Accessories] Airfrix:
Well at first I thought that screen is unscratchable... I was keeping my new SG2 and old nokia E50 in same pocket. At first sight SG2 screen is like new, but when I flick it at direct light (non-sun works best) I definately see some scretches ! So, even thou glass is resistant it is NOT invincible.
[Galaxy S II Accessories] FrenchSparda:
i bought my GS2 in June 2011...sinxe day one i was using screen protector. But since 2 weeks, i dont have anymore protection, screen is great, colors are vivid, and not even one little scratch appeared.

[Galaxy S II Accessories] leNny989:
I'm very carefull with my device, but after 2 weeks i saw couple of micro scratches. So, my answer is YES, we really need a screen protector (ofc, if you want undamaged screen). Gorilla Glass is good, but not perfect. It's not completely scratch resistant.
[Galaxy S II Accessories] slimlo:
i have had mine over a year never used protector for it....... glass is perfect, i use micro fleece cloth to clean it.... i am impressed how well the gorilla glass has proved itself to be invincible .... at least in my case
[Galaxy S II Accessories] serpentlord:
I always use screen protector. better safe than regret later. right?:good:
[Galaxy S II Accessories] GeekyNitz:
Me too. I've had mine for over a year and I never use screen protectors. My S2 screen is still as good as new
[Galaxy S II Accessories] ranzzit:
I've been using mine since September 2011 and have never used a screen protector. my screen is as good as new. i strongly recommend not to use any screen protector. gorilla glass rocks :)
[Galaxy S II Accessories] FrenchSparda:
almost 2 months without screen protector....no scratches so far :D
[Galaxy S II Accessories] Cappugino:
I had one but after this protector got scratches I removed it.

After a few weeks since then I´ve got many micro scratches.

I also get a bigger on which u can see :(

Better buy one ! :)
[Galaxy S II Accessories] serpentlord:
So some people got scratches and some people not.

I guess I'll keep my screen protector
[Galaxy S II Accessories] S2KSkyline12:
Yeaaah...I dunno about that unprotected business, My SGSII is in an otterbox and has a protector mainly because I like preserving my devices.
[Galaxy S II Accessories] timonoj:
Been using my S2 for some 15 months already, no protector from the beginning. I only try to no put the keys in the same pocket. That's about all the care it has received. Never scratched. And it has fallen more times I care to remember. Still perfect.
[Galaxy S II Accessories] Bubble-be:
When I got the S2 just the other day, there was a perfectly applied screenprotector on it. While I know my display will be a lot better, I haven't had the heart to take it off.

I had no problem running my S1 without protector for the best part of the year. Just take care and nothing much can happen to it.
[Galaxy S II Accessories] stx8:
I don't think one NEEDS one, especially with gorilla glass, but it CAN scratch (mind you, that was intentional). I had a friend who had a bricked SGS2 Skyrocket and he was getting a new one anyway so he decided to test it. Took a while with a key to see some scratch.

I've put one on my phone simply because one came with my otterbox, and I've used it since. I guess I just feel better being able to throw it into my pocket without worrying. This particular protector leaves a corner though (for camera and I guess they didn't want to bother being precise they just left the entire corner open), and I guess an interesting fact is that that corner looks spotless, while I have scratches all over my screen protector.

So I see why I understand a lot of people here not using one.
[Galaxy S II Accessories] praktical:
screen protector

while it diminishes the true beauty of your screen pending on which one you have installed variations in %. using a screen protector is just a matter of preference and not so much functionality.
[Galaxy S II Accessories] serpentlord:
I agree with this. it depends on the user. but what the Thread Starter ask is whether we need the screen protector or not. :D
[Galaxy S II Accessories] RadeonXTX:
I've was using a screen protector back then, it peeled off and i haven got time to replace it.

I have to say, if you are using a lousy screen protector, it really kills the super-amoled screen.

Now i feel better off with it.

And i think we dont' need a screen protector :). Most of us are gonna change to Galaxy S4, Galaxy S5, Galaxy S6 ...... one day anyway.
[Galaxy S II Accessories] Reiman76:
I always put screen protectors. I tend to drop my phone frequently. I know, im clumsy...
[Galaxy S II Accessories] SilviuMik:
I use Momax Crystal Deluxe Screen Protector for Samsung Galaxy SII i9100

Verry happy with it ! I know the colours are not so bright anymore and u can clearly see it has a screen protector but hey ... no more fingerprints and i can see my phone Ok in sunlight
[Galaxy S II Accessories] CrashUK:
Don't need one just buy I good case..
[Galaxy S II Accessories] Orginator:
I've bought an S2 right after it has been released, never had a screen protector and don't see why anyone would need one. My phone has been dropped several times, my pockets tend to have a key bundle in them, but it seems that gorilla glass simply doesn't care, and I've never put any care into not getting it scratched.

Sure scratching it can happen, like if you have sand in your pockets. Or a friend of mine takes his S2 to work and he's working on a construction site, he bought his also right after the release and never used a screen protector, and while he does indeed have scratches, his phone is just as usable as mine. When the screen is on one doesn't notice the scratches as much anymore.

Besides a phone is a everyday utility, and not something that need extra care. Each 2-3 years most of us anyways get a new one ;)

So whoever decides to use a screen protector, not only gives up the awesome super-amoled display quality or lowers its responsiveness but also wastes money on a useless "crap-on" ehmm add-on :p
[Galaxy S II Accessories] Cioffaz:
I've never used one, don't think it's useful at all...
[Galaxy S II Accessories] -mocho-:
In my case is more of a psychological thing, i always used a screen protector, a friend of mine never used it, his phone is scratchless and my is full of them (the protector).

So in my opinion there's no need to use one.
[Galaxy S II Accessories] zolocotroko:
I guess the protector, in certain mode, always dims the strength of the signal and that's the reason why manufacturers invest on better, harder, displays!
[Galaxy S II Accessories] CasioMaker:
Screen-protector all the way. Having a "super-duper-un-scratchable-screen" means nothing when working on the field or when living with relatives who have little kids who always want to play "Angry Birds" on your phone.
[Galaxy S II Accessories] egendomligt:
I managed to scratch mine a bit fairly early. Not sure how it happened since I'm usually very careful. Sad to say that my predecessor iPhone 4 seemed more scratch resistant. But I for one can't stand screen protectors anyways :/
