[Q] Screen protector or not?

Do you or do you not? I personally think its overkill. Screens are getting stronger and stronger and granted theres never going to be a 100% solution but for the time being my Folio case does a good job of protecting however inconvenient it is ;-)

I use a screen protector. While there are options for more and more durable glass, that is not a guarantee that the device you are using has it. My g2 for instance has 2 scratches on the screen and I was generally careful in my handling of it. if it is not known to be gorilla glass then i would get some form of protection, either a case of a screen protector. The thing that pushed me over the edge with the xoom is that I decided to go caseless for now. None of the cases out right now appeal to me.

I am not worried about protection as much as I am with the extreme glare and fingerprints. I had the same issue on my Samsung Captivate and Invisible Shield helped dramatically. I ordered the same for Xoom and hope it has the same results.

I have a portfolio case. Idont believe there is a need for a screen protector. Gorilla glass is strong. plus i dont believe there be casual scratches like with a phone and keys in my pocket

I think with most new devices having gorilla glass, its only precautionary to get a screen protector. I have had a droid X since release and have never had a screen protector and the screen is just like the day i got it. But we are talking about a 800.00 device, so then its not a bad idea to cover your investment.

I normally go without a case but for my Xoom I will get one just to help with the fingeprints.

Screen Protector and Silicone Case FTW

once stienheil releases an anti glare/fingerprint protector I think ill make a purchase because as stated, the fingerprints are terrible on this and they don't wipe off very easy.

I totally love the Frogz antiglare screen protection I have on my iPhone. Happy with it. Have 2 left. =]
Though not antiglare as none were available, I did bought 3x screen protection and of course they are cheap. As soon as they arrived, I tried to carefully apply to my Xoom but I failed after every attempt which resulted in me wasting all 3. Waste of money. ="(
The screen protections (http://cgi.ebay.com/ws/eBayISAPI.dl...5Wo6dic%3D&viewitem=&sspagename=STRK:MEWNX:IT) I received were not perfect fit for Xoom as they are claimed to be.
I'm waiting for Frogz or other to start selling antiglare for Xoom...

I would say it's overkill.
Back in those days with plastic resistive touch screen, a screen protector was necessary. But nowadays, a typical glass surface (even for non-Gorilla glass) is hard enough that it's rather hard to scratch it. If you drop your device, the glass may shatter, and screen protector is not going to help with that. And if you hit the screen hard with something sharp and strong enough to dent it, it will probably dent through the protector too. I have been using my HTC Desire without any screen protector for almost a year now, and it is still completely scratch-free.
Another reason not to use a screen protector is that they tend to be less oil- and fingerprint-proof. While Apple is the only company advertising that they have an oleophobic coating on their screens to make them more fingerprint-proof, the fact is that most glass screens has such a coating, even though it was not advertised. And most cheap screen protectors don't (can't speak for all of them, probably some more expensive ones have such coating... I don't know). I've tried some screen protectors and I found that oil and fingerprint left on the glass are much easier to remove than those left on the screen protector.
That being said, if you really really hate glossy screen, you may want to put an anti-glare type screen protector on your device. I have one on my iPad. This type of screen protector does create some sparking effect with white background, or make the texts blurry. But they don't look too bad for me, compared to the shiny glare of the iPad...

Are we sure that it uses Gorilla Glass? Ive seen a lot of people alluding to that but no actual statement, and its not on the official Corning list.
I like Steinheil as well, I've had good luck on my phones with them but they are slow to get new sizes out sometimes.

I want something only to reduce glare and fingerprints.
If installing it ends up screwing with touch sensitivity, I'll stick to stock.

When I had an iPod touch, I thought screen protectors would ruin the experience. I soon learned two things.
1. Glass is a finger print magnet.
and
2. You never know when something unexpected will come into contact with your screen. After getting a few scratches from dropping my iPod between my car seat, I decided to get a screen protector.
I got a screen protector from Verizon the day I got my Droid, and put it on right there at the counter. The metal casing of the phone is dinged up, scratched, paint is chipped, etc, but the screen is flawless.

FWIW, I've only put a Body Glove case around my EVO, but have dropped it 4-5 times (in fact, the BG case is warped at one corner after the last drop- been pretty clumsy lately ). Despite leaving my screen unprotected (and it's not GG) these 9 mos, it's still quite pristine despite all the drops and the zillions of touches (and debris, had a cold a couple of months ago!).
So. I have the silicone case (which does prevent me from using all but one iPad stand out there I tried), but no screen protector.

Funny, my Droid looks the same, with no screen protector!

I don't have a screen protector, and I don't plan on getting one. I don't have one on my og droid and I've had it since launch with no issues. Plus I can never get those things on right lol

I think the answer to this is yes unfortunately.
I haven't had it out of the house, haven't knocked it, dropped it, poked it or anything else and I already have a spot on the screen that I can't get off with Microfiber/Distilled water.
Thats pretty darn annoying.

[Q] Are screen protectors really necessary?

When I first got my DROID2, the nice Verizon lady tried to sell me some screen protectors. It was like $10 for 5 or something like that, and the Verizon people put it on without any bubbles or anything. The only complaint I have is that the screen picture quality has gone down.
My question is, how durable is the screen without one? Is it easily scratchable? I'd sure like to take it off, but can't stand to have a scratched screen.

How often do you drop your phone?
A better question would be how often do you replace the screen protector? If the protector is still in good shape (they scratch hella easy) then take it off, the glass is 100x more durable than the protector. I had a screen protector on my Voyager, and when I removed it I promised I would never use one again... the screen just looks and feels better without it.

I have about 2 scratches on the protector. One is about a cm long and the other is about 2 inches, but they are light scratches. I have never replaced it.
Also, isn't the Voyager screen plastic, while the D2 screen is glass? Does that make a difference?

I've had my D2 for over a year without a screen protector. It has zero scratches. Gorilla Glass is awesome stuff.

^This. You can't scratch this screen with a knife. I have dropped it face down on pavement and had it skid, nothing. My girl uses a protector and to me it seems like it's more difficult to use the touch screen with.
I also had a clear gloss protector on my Voyager. When I was ordering the D2 online I took a knife to the Voyager screen and couldn't scratch it, so at the time it saved me 12 bucks.

so my deep scratch must be something else

I took a "generic" screen protector, and trimmed it to fit my inspire. I probably didn't need to, but I had the screen protectors already, and figured it couldn't hurt anything.. My phone is in my pocket all day, and who knows what I throw in that pocket!

I installed a generic one, it helped with scratches and specially with fingerprints

I am very rough on phones . Another layer of protection to absorb shock and scratching can hurt anything . I use a generic screen protector and change it when it starts looking bad .

Scratches on the screens glass

Does any one had scratches appearing on the screens glass of the Galaxy Nexus?
, few days back i have noticed one noticeable scratch on the screen , strange as i am treating my Nexus very carefully.
My galaxy S which has the gorilla glass never had scratches and it is now more than 6 months old.
Little bit disappointing as it is very new phone with couple of weeks use. who know if there will be more scratches in the future!! Hope not

Just dropped mine 5ft to the pavement landed face first and the battery cover came off. It's still flawless I don't know how but it is.... I was expecting it to be cracked but I'm pretty impressed!

Yeah, I've got a few scratches. Check out http://forum.xda-developers.com/showthread.php?t=1364252

I have mine in my pocket all the time and it's perfectly fine,not even one scratch.

i used my gn with the screen film still on it for over a week until i got my screen protectors in the mail, no glass screen is unscratchable/unbreakable. there are plenty of substances around that will scratch gorilla glass (eg sand) and if even a tiny bit ends up in your pocket, better have a screen protector!

Yea my original G2x had 2 tiny micro scratches on it. Not noticable unless viewing a white background, more commonly when viewing webpages before they fully load.
The LG Updater bricked mine and got an exchange. Haven't had a problem with my new one but just goes to show.

Wise advice here, but nobody sells screen protectors for the nexus where I am. I've ordered some online and I'll be taking it to a professional to get stuck on (every time I do it I leave bubbles; yes I've watched numerous instructional videos alas I cannot do it) - I've only ordered three protectors, hopefully that is more than enough.

All the screen (even Gorilla) would have chance to get scratches...
always get a screen protector for your couple-hundred phone

Yeah I'm gonna have to get some too. I always take extreme care of my phones (whether in my pocket or out) and it already has a small, yet noticeable scratch on the bottom. Definitely need a ZAGG or the like

3 scratches here.
I'm tired of hearing people say even gorilla glass will scratch blah blah blah. Gorilla glass has proven to me to be infinitely more scratch proof than the glass on the Nexus. Like 100 fold over. After a while I was treating my Vibrant like it was bullet proof. Throwing it across the room, dropping it scores of times, putting it into my pocket with keys, etc etc... and to this day - "not one scratch on it", not one! For those who think sand in your pocket would scratch gorilla glass, you better think again. Obviously there will be rare occassions where it would happen but for the most part, it'll survive without any issues.
My nexus on the hand has been babied to death and less than a week into owning it, 3 scratches.
I will never, EVER buy a phone without gorilla glass again.

I've been rocking my Incredible since day one without screen protection and it's still mint. (besides a complete crack in upper right corner (in an area that is beyond the display) from one of the worse drops, which was more of a drunken throw). I really hope that the Nexus can handle my lifestyle, but sounds like this thread is reporting mixed reviews. I refuse to wear a condom so I hope I get one of the good ones...
p.s. I surf alot in the summer and sand all over but still no scratches. I guess it has to hit with the right angle and friction???

One grain of sand or salt + friction (i.e. pocket) and even the Gorilla Glass 2 on the RAZR gets scratched.
You can run a key across the screen all day long, but it only take a granule of something to etch a deep scratch.

If u get a decent screen protector and install it well (I know it ain't easy) it will look/feel as good as the naked glass, and then u dont have to worry - and in a year when u pull it off, the glass will be PERFECT. Small price to pay. The Galaxy Nexus is so thin that with a slim TPU case it's still crazy thin, and you will keep it in perfect condition

I agree Gorilla is scratchable but much harder to get scratched than other glass.
Does anyone have suggestion of good screen protector? And from where to get?

I'm sorry to say, but you should have ordered the SGP Flex instead. The Ultra Oleophobic ones don't extend to the edge of the screen, because they use the dry adhesive method, and if they went right to the edge of the curved screen they would peel.
Frankly, it looks pretty ugly having a band around the edge that's not covered. Plus, because they don't extend to the edges, it's much more noticeable if you get it off centre.

As mentioned in the other thread i have a couple of tiny scratches after 3 weeks of use and never ever putting anything else in my pocket with it. Disappointing.

Sand will scratch sand will scratch sand will scratch sand. What do I mean by that? ALL glass (including Gorilla Glass and its differently arranged superficial crystalline structure) is the same molecule- SiO2 or "silica." Is there variation within silica? - yes, but minutely.
[good read: http://en.wikipedia.org/wiki/Mohs_scale_of_mineral_hardness Geology and Mineralogy have huge unrealized relevancy in everyday life- just like under-appreciated physics] The variation will not give silica the hardness of say, "topaz" (at 8 on the scale), but rather is usually due to impurities (additional minerals) that weaken it down to ~ 6 or so. Gorilla Glass seems to be a purified silica, maxing out at 7 hardness. Quartz crystals (what we call "sand") also usually sits at 7 (chemical weathering can both purify and contaminate depending upon the situation), and do not have to be just "sand" like beach/desert sand. Sand is a size classification, you also have "silt" which is just smaller (down to microscopic) quartz crystals, and is "aerial saltating" (airborne- carried by the air but not in solution with it). Many other minerals may be present in the "cloud" that hovers about <50' from the earth's surface due to weathering that will scratch just about anything, so "grit" is a huge issue for ANY screen. Gorilla Glass is nicer than other glass types (although according to the Vickers scale Corning uses, not by much), but it is not invincible and items that can/will scratch are much too common to be flippantly dismissed. Also good reads in these comments: http://www.reddit.com/r/Android/comments/mfskn/galaxy_nexus_no_gorilla_glass_no_problem/
Buy a screen protector, even if you have Gorilla Glass...

Just get a high end screen protector like xoskins on there. They fill in scratches. Their video shows it pretty well http://www.youtube.com/watch?v=qoMRO4OiXw4

[Poll] Do you have a scratched screen?

I've seen a number of threads about the screen scratch issues, but i am struggling to work out the proportion of people suffering from it.
Does your Galaxy Nexus have any screen scratches?
If you don't have a scratched screen and can post to say if you take any special care with it (like keeping it on a pouch, screen protector etc...)

I have 2 deep scratches.
They are the length of the diameter of the circle exposing the front facing camera.
They're probably from sand that I was around when on holiday.
I highly doubt I would have any noticeable scratches if I didn't expose it to sand.
I was going to return it to the store I bought it from and tell them there was something wrong with it so they'd give me a new clean one, but I'm okay with it now and I returned to the UK 3 days after the 28 day return/exchange policy so I couldn't do anything anyway.
Anyone know any way I could easily mask these scratches? They're on the left bezel so they don't interfere with the screen but I'd like to mask them anyway.

No scratch, no screen protector (hate those things).

just put on a cheap ebay screen protector and you'll be set
nothing to make a big fuss about for some scratches when it can be easily prevented with a $2 screen protector
even Gorilla grass gets scratches too

Have you found your screen protector has stayed on correctly? From my past experience they seem to start peeling from the corners.
I really want a Galaxy Nexus, but I know my OCD will really get to me if I get a scratch on the screen.

My phones with Gorilla Glass have never had any scratches whatsoever. This is my third phone too. I carry it either in my pocket or man purse lol

I've had a few minor scratches in the bottom left corner of the screen due to the dropping it a month ago. Now, I've got 3 more, quite visible scratches on the screen. Despite the fact I dropped it once, I take care of my Nexie. I keep it in my pocket, without the keys. I don't have screen protector nor the case, pouch. My girlfriend who's got Desire S(no screen protector) has got no scratches on the screen, even though she keeps it in her purse.

Gorilla glass is still just glass, its not magic, it can be easily scratched by something harder than glass. take a bit of sand and rub it on it and you will have a scratch.

I just got a small gouge in my screen, not even 1mm wide, near the middle some time yesterday. It's more of a chunk, then a scratch. Reminds me of a minor impact. My phone is in a holster, never my pocket. I was working on my car, and may have touched the screen with a less than clean hand that led to the scratch. About 1 week after the phone I got a small scratch near the top of the phone, out of the visible area.
I have a stenheil / sgpstore Oleophobic on the way. i was holding out for a Ultra Crystal by stenheil (best screen protectors ever made hands down IMHO) but it doesn't seem like they're going to make a crystal for the gnex due to the curved screen :-(

anyway no screen protector but got scurve case for it, also have it in my pocket with nothing in it but a micro-fiber cloth because that's just how I roll. Also always leave it face down on a clean surface. (curved screen so screen doesn't touch the surface woohoo!!!!)

No scratches only had mine for a week though, no screen protector and just in a TPC case.
I have had my fascinate for a year with no scratches and plan to use Nexus same. Hopefully it stays scratch free.
I always keep it in my right front pocket, where nothing else ever goes in there.

Just sat on my nexus and ruined my... screen protector! Thank god... this would have definitely ruined my screen.

No scratches yet
I've had mine for 2 weeks now. Thankfully, no scratches yet. I was really worried about the glass on the Nexus with some of the forum threads I had come across. I was coming from an OG with Gorilla Glass.
So far, in 2 weeks of use (treated the same way as my OG Droid) I don't see even the slightest of scratches. I also love the oleophobic coating on the glass. It really does.wonders.
In comparison, my OG had a big scratch on the screen in the first 2 weeks of owning it, and it almost got me to switch to a screen protector. Not that it means that the glass on the OG was worse, but rather, that these things are all luck related. I'm sure that over 2 years of use, my SGN will also have scratches, just like my Droid did.
Gorilla glass/ reinforced glass is not magic. If you're unlucky, either can get scratched in a heartbeat, no matter how careful you are with your phone.

No screen protector and I have scratches on my screen.

I have some micro scratches on it from day 1 before i was able to apply a screen protector. Seems like the glass is not as hard as my old iPhone 4 where i used it w/o protector for over a week and it seems fine.

Believe it. My old G2x had 2 scratches on it. Luckily I had it replaced when an update bricked it. First phone with a Gorilla screen and the only phone that got scratches. Sand and dust are destructive on them. Knives and keys... not so much.
This time I put a screen protector on. XO for me... and a case. No chances.

So, are there any methods of masking scratches after they appear?

Are tempered glass screen protectors necessary?

Hello. I just ordered a OnePlus one, and now I'm looking for the accessories.
I actually have a Note 2 with a tempered glass screen protector. The other day I've met a friend that works on the construction and he died me his Note 2 that he had been using since 6 months ago, and the screen was perfect, without a mark. He sweared that had the phone dropped several times and the screen was, as I said, perfect.
It made me think that maybe the OPO with a Corning Gorilla Glass 3, maybe it doesn't make much sense to use one of these screen protector.
What to you guys think?

Not necessary but if you want the extra protection go for it.
I personally don't use screen protectors but its ultimately up to you.

I don't usually run screen protectors but I'm glad I got one for my OPO.
After a few days of owning it I noticed some super light scratches on the bottom of the screen. This was during the brand new period of owning it and the screen had not touched anything except empty pants pocket, my fingers, and t-shirt for cleaning.
Thankfully my ozrly tempered glass protector showed up the next day, and I've been running that since. Pretty happy with it.
Tl;dr: I'd run a lot of phones naked, but not this one.

Precisely, as this is a cheap phone, and also has gorilla glass,I don't see the necessity as in a Note 3 or an iPhone...

as cheap as it is at $360, a $6 protector won't hurt your wallet

The phone is inexpensive but difficult to repair or replace. I see someone doesn't know the difference between the cost of something and how valuable something is.
I always keep my phone in a dedicated empty pocket but it always gets the random light scratch over its lifetime. A good $15-$25 glass screen keeps it looking new. That way when you pull out your device you don't look like some kind of a hobo.

The Ringke Fusion comes with a screen protector free of charge when you buy the case by the way.

All you need to scratch your screen is a grain of sand.
Are glass protectors mandatory? of corse not, otherwise they would come in the package with the phone. That said, i firmly beleave they are a "must have" for any phone, as you will regret not having one as soon as you get a scratch on it. for my xperia z2 it lasted 1 week 'till i regreted not having one, when for the first time I went "YOLO" on a phone.
You don't need a 30 dollar glass protector, I've had all kinds of brands and prices and all i have to say is that they are all the same, the only thing I insist on is rounded edges, so you don't feel it as much.
I'm on my second OPO, since I sold my first one after it fell face down, slightly tilted up, since it damaged the chrome ring on the top. When it fell, along with the dent, the glass screen protector was shattered on the top left. If you did not realize this so far, the only reason my "amazing gorilla glass" did not shatter aswell is that the protector took the hit for it (shattering to spread the energy). Gorilla glass is made to take scratches, not falls.
Finally, it is up to you. Do i think you do not need a normal plastic screen protector? well, you don't. Do you need a GLASS screen protector? after my experience my opinion can only be yes. I am currently waiting for a new one and have a crappy regular protector on.
Ultimate shield has proven to be a very good, not very expensive, and reliable seller for every phone I got it for (htc one m7, note 3, xperia z2, OPO)

Not absolutely necessary, but you really can scratch the phone screen.
Plastic screen protectors scratch really easy because they are plastic. So even if it protects the screen they end up looking like crap. That's where tempered glass protectors shine, it protects the screen and still looks really nice (albeit at a higher cost).

Tempered glass screen protector is never necessary until...well, until you drop the phone once on a wrong surface...
Take your risk.

I never really believed in tempered glass, until I saw more videos on these types of ion-reinforced glass. They are definitely not indestructible. As somebody above stated, all it takes is a grain of sand for there to be a micro-scratch on the screen. It's from these nearly-invisible weaknesses that the screen will crack when exposed to force when dropped. I believe the reason is that Gorilla Glass 3 is around 6-7 on the Moh's hardness scale, which is harder than metal, which is why keys and knives don't scratch it, but not as hard as sand or rocks.
So in other words, some type of protector will prevent these micro-scratches. The question is then, plastic or tempered glass? I've always used plastic on the last dozen or so phones and tablets I've had, but even the best plastic one (Belkin) still definitely felt plastic in their friction, it wasn't as smooth as glass, and a year later, there are small scratches in it.
Yes, it's true that the OPO is cheap enough that if you smash it, it's not a huge deal, and yes, there was a screen replacement kit I saw in another thread that was $110 or something, BUT it's the time and hassle. For me, slapping on a $15 glass protector (which I found easier to apply than previous plastic protectors), is worth it.
With the OPO, I decided to try a Nilkin tempered glass protector, and it feels as smooth as the original glass, which is great if you're a power user that does alot of quick inputs. It also seems to be very resistant to scratches so far, but I don't believe it's the 9H that they stated in the ad. The downside is that it's definitely noticeably thick, you can see it from the side, and you can feel the edges next to the cutouts.
PS. I'm no expert, so take it as you will.
