Product Details

The Steinheil GLAS.t NANO SLIM for the Samsung Galaxy S4 is made to cover and protect the LCD from damage and scratches with specially processed transparent glass that has been reinforced for scratch resistance. The glass has been designed to have a slim thickness of 0.15mm. GLAS.t NANO SLIM is currently the thinnest glass screen protector in the market! The 0.15mm thickness makes the GLAS.t NANO SLIM compatible with all types of cases while still maintaining a surface hardness of 8~9H. When installed, there are no gaps between the LCD and the GLAS.t SLIM which means the touch screen's sensitivity is unaffected.

  • Innovative profile : GLAS.t SLIM is 0.15mm thick and made with chemically treated, transparent tempered glass.
  • Surface hardness : 8~9H : The surface of the GLAS.t NANO SLIM has a hardness of 8-9H, three times stronger than regular PET film. Even sharp objects such as knives and keys will not scratch the GLAS.t SLIM.
  • Oleophobic Coating : The GLAS.t NANO SLIM has an oleophobic coating that prevents fingerprints and other contaminants and makes the film easy to clean.
  • Delicate Touch : The GLAS.t NANO SLIM is coated on the back with a strong silicone adhesive that makes installation easy and attaches the film firmly so as to not affect the touch screen's sensitivity. Out of the entire GLAS.t series, the NANO SLIM provides the best installation results with no air bubbles.
  • Anti-Shatter Film : If broken, the GLAS.t NANO SLIM cracks into small pieces that are held within the film. They are not sharp, making it safer than other glass products.


*When removing for re-use, the adhesive properties might wear off to an extent where the screen protector will not adhere to the device. It is not recommended to reuse the GLAS.tR SLIM once it's been applied. *Using excessive force when installing or removing the screen protector may damage the product.

Q. How much slimmer is the GLAS.t Nano Slim from the GLAS.t Nano?

A. The GLAS.t Nano Slim has a thickness of 0.15mm and the original GLAS.t Slim has a thickness of 0.23mm.

Q. How do I install the GLAS.t Slim?

A. Use the provided alcohol swab to clean your device and make sure that the surface is completely dry and clean afterwards. The tab labeled "Back" is the protective film that covers the adhesive (sticky) side of the screen protector. Carefully center and align the Nano Slim glass with the cutouts of the screen and slowly begin the application process. Press down on the center of the Nano Slim, then swipe from the left to the right. The Nano Slim EASY SYSTEM should adhere with minimal pressure. 

If air bubbles get trapped under the Nano Slim use the squeegee to remove them, beginning from the center. Smaller bubbles should disappear within 1-2 days. 

Q. What happens if I mess up on the installation or something goes wrong with my GLAS.t?

A. You do not have to worry! Your GLAS.t is protected by our GLAS.t Low-Cost Replacement Program. Simply return the GLAS.t product back to us with the replacement form filled out completely. You can find the form here: www.spigen.com/need1more

Q. How do I remove the GLAS.t Nano Slim?

A. The GLAS.t can be removed by using a hard card like an ID, credit card, or even your fingers. Lift the GLAS.t with the card from any corner of the screen protector. Once the corner has been lifted off the device, hold the corner and remove slowly. If the GLAS.t cracks, it will not shatter. The GLAS.t will not damage or leave residue on your screen.

Q. What cases will work with the GLAS.t Nano Slim?

A. All of our SPIGEN SGP cases will work with the GLAS.t Nano

Q. Is there anything I should take caution of when using the GLAS.t?

A. The GLAS.t is made from real glass. While it is tempered to shatter within the film when dropped, there are some things that you need to be aware of when using the GLAS.t. As with most glass products, the edges of the GLAS.t are the most vulnerable areas on the screen protector. This means the edges are the most likely to chip or crack when pressure or force is applied to it. If you see that the edges have chipped or have cracks, please remove the GLAS.t from your device as this can be potentially harmful. Please take care that your device is not accessible to children if your GLAS.t begins to crack. We highly recommend that you use a case along with your GLAS.t screen protector to avoid chipping along the edges. Also we would recommend using a case to protect the edges against any unwanted lifting.

Q. What if I have more questions about the product?

A. Not a problem! Please contact our Product Development Customer Support team on Helpdesk! www.spigen.com/contacts

The best! Review by Ray

It's going on 7 months now since I bought this for my S4. I remember thinking at the time that it was a little on the expensive side, but I always had the philosophy that you get what you pay for with protection products.

Seven months on now, and I have yet to regret buying this thing, and knowing what i know now, would do it in a heartbeat without even thinking about the expense.

Installation is a breeze, but do make sure that the screen is ABSOLUTELY spotless and no dust has settled. The suggestion for doing it in the bathroom after a shower is a good one. Aligning it is easy, I used the home button for reference. After it is aligned, just let it down - it seals itself without bubbles.

I actually think that it makes the screen easier to use - must be the oleophobic coating - you fingers slide so easy. Best part of that coating is the the normal 'cheek grease' never builds up. Also, none of those little plastic grooves you get with the stick-on products (like the one that advertises it protects helicopter blades - which i pulled off for this!)

I had the phone on my desk at work, someone tossed a gold Cross pen (not the slim one) over my 6' cubicle wall and it bounced right off the screen, point first. Everyone around just froze, waiting for my scream! Not a mark! (But I am still in possession of a NICE pen!)

I got the hybrid case with it, and since I installed everything, I never worry about the phone. Jeans pockets, coat pockets, tossing it on the desk...just doesn't worry me any more. Just buy it!

Amazing Product, But Be Careful With It Review by Nick

This has to be the best screen protector you can buy for a Galaxy S4. It feels like there is nothing on it, unless under close inspection, and air bubbles are no problem.

However, since this is a tempered glass screen protector, do take caution when installing it onto your device. Take your time with the installation, and do everything they say in the instructions. Make sure that it is aligned perfectly the first time. I strongly advise anyone using this screen protector not to try and re-adjust it after installing it. I cracked mine in this way, and though it is still not visible unless under close inspection, don't try to re-install it. Even if there is one or two little air bubbles, they will disappear after some time, and re-installing it will only allow for more air bubbles to form.

Also, unlike other screen protectors, it does scratch, especially around the edges where it sits just above the bezel of the device. I highly suggest using a case with this screen protector. Any old one will do, but I'm considering getting a Neo Hybrid case to go with my phone.

I have taken one star off for design, as i believe that the protector for the back of the phone is a little sloppy, but that's not the star of the show, and in my opinion is only a bonus.

All in all, this is a great product, and I highly recommend it.

Amazing Review by Amy

Just finished the installation, which was super easy, and am absolutely amazed. I had purchased another glass screen protector from phone provider and hated it....too thick and bubbles never disappeared. Did some research and found this one. It's actually a great value compared to the competition and much superior. You cannot tell there's anything on your phone except I swear it responds faster than without this. There were a few negative comments about install but I cleaned my screen then went over with the cloth that came with it. I went to wash my hands and doubled checked for any dust that may have settled, there was one, blew it off and put it on. I placed it so the oval opening for on button was slight lower and it's perfect. By being just lower you don't need to put the button cover on. It's perfect....I'm so happy I purchased this one and will replace my iPad protector now with one of these.

Awesome Product! Review by Mark

Ive went though so many screen protectors in my time I probably could have bought 5 of these. I just got my Galaxy S4 and learned about this product. After watching videos and reading about it I took the plunge and ordered one.
It arrived today and installation was so easy. It sealed up perfectly and no bubbles.
It feels fantastic and when you touch the screen your reminded of the quality of this product. Buy this and you'll never need another screen protector as long as you own your device!

Amazing! Feels like a new phone Review by Dave

The Glast Nano slim is amazing and by far the best. This is one product that actually does what it says and has exceeded expectations. So glad I got rid of my orange peel "HD glass like feel" and installed my glast nano slim. I can now enjoy my screen how it was meant to be. Its extremely smooth to touch and clear. The install was easy, the nano slim fits perfectly. Thank you so much for making this product.
