Is the display just plastic?

Just curious, is the display plastic on the G2? I honestly cant tell

I got a screen protector... just in case. I see many phones have decent screens that do not scratch, but I always go with the protection. Also, I have a house full of destructive kids who do not respect daddy's things.
I think everyone is afraid to say things that may sound like a guaranty. We may have to wait until a brave technician tears one down.

plastic screens scratch and dent like crazy. kind of wish they went with glass.

wow, i managed to scratch the gorilla glass screen on my vibrant so i guess i better get some sort of screen protector on this thing asap, sucks they didnt go with glass after putting all the aluminum trim on it

Lol I doubt its plastic

I'm pretty sure it's plastic. It's quite hard, but still, I think it's plastic. If it were glass, I don't think they would cut a hole in the edge for the speaker to peek out from. That edge around the speaker is also beveled. Again, something I doubt they would do to a glass screen.
Also, glass is very good for holding an anti-glare coating. The Vibrant's glass screen had one. (Ever notice how glare reflections were colored blue?) That's an extremely thin metallic salt coating on the glass (Magnesium Flouride is a popular coating). As far as I know, it's easy to do on glass, but harder on plastic, and is usually reserved for eye glasses. (And may even be a different technology then.) If it were glass, I think they would have used an anti-glare coating. Then again, HTC could just be shaving off pennies by not using an anti-glare coating. But I sill think it's plastic.
I'm just guessing. I'm no expert.

Thes screens on just about all phones are neither plastic nor glass, it's a combination of materials.

Plastic kinda like lcd tvs. I use to have a plasma an i loved the glass on it but glass cracks plastic takes alot before it does anything.
Either way its a nice screen to me and i bet we wont have the screen cracking problem like the nexus ones. Also always use a screen protector its just smart your always have new screen under the protector if the protector gets scratched just replace it. Better then getting another screen.

Of course I don't know how credible this is since I couldn't find any mention of it in the references.

Wikipedia should never be used for definitive reference.
All of these screens are "glass", because they are silica based.

Glass. Look up some capacitive TS or mobile phone coverglass spec sheets.

Turn off the screen and look at some glare. You can see wavy inperfections. Glass would have this. It also doesn't feel as hard as glass when I try to scratch it with my fingernail on the edge near the speaker.

Tempered glass recommendation? (not XGear please)

Hey guys, I'm having trouble finding any brand left that sell tempered glass for this phone.
The only one I found is XGear, base on the image I am certain that the designed is by having the adhesive stickers on the bezel/edges only, while the viewable area isn't adhesive. I have used tempered glass of similar design before and it is terrible. Since the adhesive stickers are thin on the edges, its not very durable and can leave gaps or pop out (especially since this is a curved screen), and let water in. It will also cause "rainbow effects" due to the gap between the two glasses. There are Amazon reviews that reflected my concern.
I'm looking for something like this which have the entire surface being clear and able to stick.
Doesn't seem like there are any available, but I wouldn't mind using tempered glass for another phone model that could fit on the Nexus screen, I think that's the best way to go. But I won't receive my Nexus in a few days, then I can see if the screen protector of the Moto X fit inside the Galaxy Nexus screen.

Bought a Nillkin Tempered GLass for my Note 3. Guess what.....after a month, the screen cracked by itself! I'm very sure it was not caused by wrong handling nor impact. All this 9H hype by Nillkin is just bull! Choose another brand!

Well I just decided to order a second i-Blason for the Moto X and put it on the Nexus. Kind of awkward, but it work. Couldn't fully stick because of the curved glass though, but the adhesive is durable enough so I'm not worried.

Was gonna buy the xgear thanks for the insight!
Galaxy Nexus
ROM: SlimKat 4.4.2

funny how purchases get based on "user" reviews. i read all 12, and the bad reviews remind of typical users that don't read directions, don't follow directions and then think if they pitch a fit with the manf and bad mouth the product they'll be redeemed of their stupidity.
dust under the screen or lifts at the curve?
1. poor cleaning prior to affixing
2. repeated removing and reapplying and failing 1.
it cracks? really? it's glass, treat it as such and pay attention to 1 & 2 above.
install tip: align and start from one end. it's not a bumper sticker, do not apply it as such.
dots and rainbow? if turned off and angled just right you can see it. turn it on and they're gone. the rainbow kind of reminded of how some windshields look while wearing polarized sunglasses.
i mostly lurk these forums but couldn't let this go. i've had my xgear tempered glass protector on for 2yrs without issue. i will buy more from them if available and my device doesn't have gorilla glass.
well worth the $30+ i spent at the time, has saved my phone too many times to count.

I'm also looking for a tempered glass that is different from Xgear...

I just installed an xGear Fantom (and just replaced my broken screen), I don't see any rainbow effect. I did notice that the protector at the sides sat flat against the screen, but were it curved it bowed out in the center. Looked clear, but definitely was not flush against the glass. I put a thick sock on the screen and some weight over top of it (a thick heavy hard cover book and a medium sized socket set), and that eliminated the bow and put a massive rainbow bubble into the middle of the screen. I lifted the top right corner of the protector slightly and the bubble moved straight out on it's on. It now sits 100% flat. I don't notice any loss of touch sensibility. As far as I can tell, this is going to work well, and last a loooong time.

xGear Fantom is expensive to me and it has bad critics. I'm trying to find another alternative although it is to another model of mobile with the similar screen's sizes 135.5 x 67.94 mm and the holes fit well. The Moto X's screen seem too small.

I think only xGear makes a tempered glass protector for the G'nex. Might be able to use one for another model, but I don't think it would work any better and you would have a higher chance of running into poor fitment.
But I do understand what your saying - some G'nex have a sensitivity bug that the xGear exaggerates (I'm lucky I don't), while some people have had problems with the glue giving out as well as sensitivity issues not related to the bug.
I'd think you could run into those issues with any brand of glass screen protectors, and further might run into other issues with fitment if the protector is for a different phone.
I can't say if I'll have adhesion issues (and so far nope - but only been barely a week or so since installing it), though I think I would have both if I had not noticed and taken care to eliminate the slight bulge out where the glass curved.
Mine did lay flat at the sides along the protectors boarder, and while it was clear for viewing the screen (as in it didn't look like I had air trapped under the protector), it was clearly bulged out (due to an air pocket) a few mm in the center of the screen where it naturally curves when viewed from the side - I was able to correct that with the weight and slight lifting of a corner.
Sadly, you may want to run your naked (no protector) or with a PET film protector.

BTW - I only paid something like $11 (Canadian) for my Fantom, and that includes shipping. I don't think it was a huge expense at all.

I think it's not necessary to use any kind of screen protection.
I have my GNex more than 2 years without using screen protector and it doesn't have any scratches

I bought a tempered glass protector ( Moto X) to my Samsung Galaxy Nexus
Unfortunately I did not find any that fit perfectly but it work rigth to me.... it was very cheap in aliexpress, only 1,60€ :good:

To screen protector or not to screen protector?

Do you use a screen protector or not? Please be sure to vote!
If not, is the Gorilla Glass enough, or does your naked screen have scratches (or worse)?

I haven't used a screen protector so far and I regret it. There's no deep scratches, but there are micro-scratches that are visible in bright lighting...

I've had the same experience. I didn't use a screen protector for a period of maybe, 3 weeks? And noticed the micro scratches also when viewing the device at extreme angles. [near 180 obtuse angles? Or near 0 degree acute angles respective to the plane of the phone? Sorry math people.]
One of the few things about the phone that make me a little disappointed with ZTE.
Since then, I've been using a liquid screen protector and it works well.. I've dropped my phone once. From about 4-5 feet up onto concrete with no damage to screen but a metal flake on the upper and lower housing.
I would recommend using something.. Anything, as some protection is better than no protection. Be it from micro scratches, hairline cracks, or complete screen destruction.

The problem is Gorilla Glass 4… It's more prone to tiny scratches than Gorilla Glass 3. But don't most smartphones, including the iPhone and the Samsung Galaxy line use GG4 as well?

No screen protector here as I couldn't find one, and luckily I have no scratches at all. The screen seems incredibly resistant!

So you removed the one that came pre-installed on the phone?

Actually the EU version does not come with a screen protector. So maybe he has that version. i do

That's the reason I've always uesd tempered glass - micro scratches! To all the people thinking it's because of keys or coins, etc. in your pocket- it's not, as most keys and coins are usually softer metal that can't scratch Gorila Glass (that's how they're able to make keys for you from blanks).
It's little particles of sand that can end up with the rest of your pocket lint that's believed to be the cause of microscratches. Sand is usually silica which is 6-7 on MOH's scale for hardness which is above what any of the Gorilla Glass 1-5 has been rated to protect.

I'm now on my second Axon 7, due to a cracked screen. I was using an aftermarket flexible protector. Looking for a tempered glass option for the replacement phone.
On the upside, ZTE does at least include accidental damage coverage in the warranty. It's still $80 for accidental damage, but that's a heck of a lot cheaper than buying a new phone or getting the screen repaired.

Which aftermarket flexible protector? How did it get cracked, and which case were you using, if any?
In my opinion, the case is the most important element of protection from cracking in case of drops, unless the screen hits something sharp, like a rock or the corner of something —*that's when you need tempered glass.

Good point. I wasn't using any kind of case, and it likely would have helped in my scenario. The protector was a DeltaShield BodyArmor Full Coverage Screen Protector. I dropped the phone on to my concrete porch. I think it hit flat face down on the concrete.
I have 2 different cases on order: a Spigen Rugged Armor case and a CoverON Hard Slim Hybrid Kickstand case. We'll see which one I like better.

How to properly apply Nillkin tempered glass on Asus zenfone 3 ze520kl

Ok so you bought a zenfone 3. Beautiful little piece of hardware isn't it ? The glass and metal design looks premium alright but it would be a pity if you got the screen all scratched or shattered. Remember that gorilla glass 3 is scratch resistant not scratch proof and it can be scratched quite easily by dust particles and sand. Also it can be easily shattered like any glass. Only sapphire glass can be called scratch proof but you won't see sapphire glass mass produced for smartphones screens any time soon because it's too expensive and very difficult to produce for larger surfaces.
So the best way to protect your precious screen is by applying a sheet of tempered glass. It has a higher scratch resistance than gorilla glass and it is designed to shatter on impact to dissipate the shock energy that would otherwise destroy the screen glass. It is very easy to apply on smartphones with flat screen surface but there's a catch. There is a new design that's being implemented on smartphones screens for a while now with curved margins and all which is generically called 2.5d glass. Zenfone 3 features such a screen. So what's the problem you may ask ?
Well long story short this means you can't apply a flat tempered glass on a screen with rounded margins without the manufacturer being forced to reduce its dimensions to only cover the flat surface, unless you can find a manufacturer that produces tempered glass with curved margins. So far I could only find such screen protectors for the Galaxy Edge series. They are nowhere to be found for our beloved asus zenfone 3 for example.
So yeah there are plenty of flat screen protectors for the zenfone 3. I myself got one from Nillkin. It is carefully dimensioned to only cover the lcd on the left and right margins. Problem is that the curvature of the screen starts somewhere from 1-2mm from the inner side of the lcd depending on the manufacturing tolerances. This means that even if you perfectly position the tempered glass there will still be 1-2mm on the margins that will hang in midair because it can't stick to the curvature. From what I could find this issue is commonly referred to as the "halo effect". And it's ugly as f*ck.
So there's good news and bad news. Good news is that I've found a way to properly apply the tempered glass even on the margins. Bad news is that you need some tools you won't find in the original package, namely a VISE (yes, that thing on the WinZIP icon) and SILICONE OIL or VASELINE (both have to be perfectly clear with absolutely no colour and make sure they don't change colour in time).
I only did this once with a Nillkin tempered glass for my ze520kl but it should work for any curved screen.
Ready ? Ok so go ahead and perform the steps as indicated on the original packaging (clean the screen with the alcohol wipe, dry the screen with the dry wipe, dedust the screen with the anti-static sticker, perfectly align the screen protector and apply it). Obviously it won't stick to the margins so here comes the hard part.
This is going to take a lot of patience but not much effort. The key to sticking to the margins is a lot of constant pressure and if that fails this is where the silicone oil comes in handy to fill the gap between the screen and screen protector.
So this is what I did to get a perfectly applied tempered glass on my zenfone 3.
-First I tried to fill the gap on the margins with a drop of silicon oil and then I applied pressure on the margin intermittently with my thumb to help the silicon oil to get inside the gap easier then I wiped the excess. The purpose of the silicone oil is to create a clear visco-elastic medium, a bridge if you like, for the light to travel between the screen and the screen protector without changing path (without too much refraction). Problem is that it can't fill the whole void and you still get a bit of halo here and there as there is still some air trapped within the adhesive.
-This is the part where the vise comes in handy. I strongly recommend you use a vise with rubber protection on the jaws (or whatever they're called). You could in theory do this with your thumbs but it is very hard and tiring and you can't apply constant pressure for a long time.
So I fitted a margin of the screen in the vise and tightened the jaws hardly enough to forcefully compress the adhesive and remove the air bubbles trapped inside but soft enough not to actually crack or damage the touchscreen. Then I left it in there for about 1 hour on each of the 4 sides. If there was still some air trapped in the adhesive I would apply some pressure with my thumb to stir it a little and then I put it back in the vise and leave it for a while longer until there would be no air left.
After 4-5 hours I got a perfectly applied screen protector on my zenfone 3 with no halo effect on the margins.
Since I've never done this before I have no idea how long this will last and if the problem will ever occur again. But if it does then all you need to do is just apply some more silicon oil periodically and you're done. There won't be the need for the vise anymore.
Good luck and I hope this bit of information will help someone in the long run to develop and perfect the method. I doubt the average user has a vise installed on his/her desk so this tutorial is mostly intended for the more savvy people. Don't blame me if it doesn't work for you or if you damaged your phone.
Also, I suspect that on various models of smartphones there won't be the need for the silicone oil and all you need is just some good constant pressure.

Accessories Screen protector with Gorilla Glass Victus glass

How good is Gorilla Glass Victus glass? Will it still need a Screen protector? The curved edges make my hesitant about using a screen protector.
Thoughts?

I looked at JerryRigEverything's videos on the S20 Ultra and S21 Ultra (or Gorilla Glass 6 vs Victus)
It seemed that it scratched just the same. I also saw an article where the Corning person admitted that it'll still get scratched by sand, dust, coins, and keys in your pocket.
That said, I haven't decided what I want to do yet. I love tempered glass protectors but they're usually terrible on curved screens and I hate the plastic feeling ones.

It's still a 6/7 on mohs scale.
The only difference is that Victus is slightly more durable, meaning it can endure a bit more force/pressure (newton), something like 8 instead of 5. So your phone will still break and scratch, but it requires a bit more effort to damage it.
Of course it won't help you with sand or anything solid that might make a dent with little amount of effort/pressure.

I haven't used screen protectors in years now. Just don't keep your phone in the same pocket with your keys and you'll be fine. There's only a small percentage of people out there who would need a screen protector, because they operate in rough environments.

I wish it was this easy in desert climates. Even with shaking out my pockets regularly, a stray piece of sand always manages to find its way to my screens within the first couple months.
FWIW I had the S21 Ultra before this (also using Victus) and it managed to get scratched. Nothing deep, but it was noticeable in sunlight. I'm planning on keeping the Pixel for a good while, so I actually picked up a TPU screen protector for it.

At this point there is no such screen protector that doesn't degrade usability of this phone. Curved screen AND the damn on-screen fingerprint reader made sure of that. It's down to everyone's personal philosophy, but in my view the phone should serve me, not the other way around.
For what it's worth, even without screen protectors I didn't have any visible scratches on my Pixel 2 XL or 4 XL, after 2 years of usage each, so I'm gonna risk it this time too.

After 6 days I have the first scratch in the display. The device was always carried isolated in a cargo pocket. I will probably send it back.

Sand will scratch any type of glass. I had a old S4 that was nearing the end of it's service life.
It had no scratches after over 3 years and bare glass feels better so... within 3-4 months with no protector it had 3 easily visible scratches. In spite of keeping it as clean as possible using a microfiber cloth for cleaning.
Unprotected glass will get scratched...

I always put screen protectors on my phones until I got the Essential Phone. No tempered glass screen protectors would work on it, and I did not like the alternatives. I decided to go without one and just "try" to be careful. It did not take long before I had a lot of tiny scratches all over my screen. When I got a deep scratch on my PH-1, I went back to the TPU wet apply screen protector that I did not like, but it is better than the alternative. I did not use my Pixel 6 Pro as my daily driver until my screen protector arrived the next day. I have to say that the TPU screen protector I purchased is much better than the one I used for my PH-1. Very pleased with it. I think the brand is IMBZBK or something like that. I have never heard of it before, and only got it until I could get a brand name protector. I may continue using it until it gives me trouble. I highly recommend a screen protector on your Pixel 6!

Modern phones displays can withstand a 6-7 on Mohs scale.
Sand is a 7.
Hardened steel is, by the way, 7-8.
Aluminium is, by the way, 2.5-3. Only because it's mixed with other metals & refined can it withstand some of the everyday life abuse. It's still **** compared to hardened steel. It's a shame that only Apple uses stainless steel with their IPhones. I would love to have a Pixel with stainless steel. The few grams I don't care about, give me the durability...

Apples Sapphire is sh*t. It's fake. They only use a partial sapphire screen, which means that it's hardness is still a 6-7.
I think HTC's sapphire U Ultra is the only phone/smart device to date with a decent ("real") Sapphire screen. Other than that you will only find expensive watches with a pure Sapphire screen.

To my knowledge optical sapphire has only been used for camera lense protection. Optically it's not as clear as glass, it has a slight tint. I still wouldn't buy an Apple...
While sand is the most common abrasive floating around it's not the only. Gravel can range up to RH 8 so a screen protector can save it from marring in a glancing slide or a low impact drop.

I can only repeat myself: Apples implementation of Sapphire on their apple watches & on the backside of devices (camera lense protection) is fake. It was tested all day long on Youtube by people using Mohs picks, it scratched at 6 and 7, which means that it's only Sapphire in name. There is no optical "sapphire" used by Apple, it's a fancy marketing word and only that.

Yeah as said before marketing nonsense. I think the saphire would shatter too easy if they needed to get it that thin for weight control
