Quick Look: Spigen Ultra Thin Air Case for the Nexus 4

Nexus 4 Case Spigen Ultra Thin Air

The Ultra Thin Air case that Spigen SGP creates for almost all of the newly released flagship phones has always been one of my favorites. As someone who favors minimal cases that don’t add extra bulk, this is one of the two that I always turn to (Rearth’s Ringke SLIM being the other) for testing. Now that their Nexus 4 Ultra Thin Air is available in black, I thought we’d take a quick look at it, since many of you seem to be fans of the minimal case as well. 


As you would expect with a name like “Ultra Thin Air,” this case adds almost zero thickness or bulk. It’s incredibly thin, and also lays almost flush with the sides of the device so that you can come close to getting that same waterfalling feel on the edges when swiping your finger across it. The corners stick up ever-so-slightly so that when laid face down, there is a bit of a lift off the ground to prevent scratching.

The material is plastic with a soft matte finish. It’s not slippery, yet also not super sticky. Wireless charging still works through this case, though it can be a bit finicky, something that shouldn’t surprise anyone with a Nexus 4.

vs. Ringke SLIM

So how does it compare to the Ringke SLIM we looked at? It’s a tough battle. The Ringke case sticks up a bit more in the corners to offer more protection, but both should do the trick for those who choose to lay their phones face down. The Spigen case, which seems impossible, is actually slightly more minimal. It comes up slightly less on the sides, but I believe this also makes it not grip the device as well as the Ringke. I don’t think the Spigen case will fall off of your Nexus 4 without some work, but it’s definitely easier to slip on and off than the Ringke. Something to keep in mind. The Ringke case also comes in a variety of colors – the Ultra Thin Air is only available in black at this time.

In a price battle, you’ll find the Ringke at $9.99 and the Spigen at $19.99, but keep in mind that the Spigen case also comes with a cleaning cloth and a screen protector (valued at $14). Tough decision, but both are really nice minimal cases.

  • All the hard plastic cases that I have ever owned for my devices have always broken in one way or another (a few cracked in half, a few had the clips that hold them on break off, etc.). I finally got fed up with them and after searching I found the Soft Gel TPU cases! I don’t know what it is but they make the device a lot more durable and they make it easier to grip the device. Best thing is they are flexible so there is plenty of room to leave say an extra $20 bill and drivers license / credit card when going out!

    Kellex, do you think it (or maybe the RIngke) offers enough ‘shock absorption’, compared to like a rubbery TPU case? My main worry is protecting the phone from falls, since I think a simple bumper can take care of avoiding scratches from leaving it on surfaces etc…
    And from what I read, you think the Spigen is better about keeping the ‘soft edges’ feel of the nexus? Thanks!

    Probably I’d like to get a pouch instead.

  • Elago makes great cases as well.

  • angermeans

    I just got one for my iPhone 5 great looking case this looks a lot like it anyone with a nexus 4 should be very happy

    • guest

      got one for my s3, but i feel its still slippery. And iphone 5? you left us?

  • ChristianHayden

    I would like to know how this compares to incipio’s feather ultra thin. I do like the soigné though.

    • angermeans

      I like it better than my incipio but the incipio was for my iPhone 5 not nexus 4. The Spigen is lighter and much more minimal. I’m still going back and forth about getting me a nexus 4 and ill gladly pick up another Spigen plus their ultra crystal display protector is the best on the market and it also comes with one of these with the case and all for $19.99. That’s a steal

    I’ll stick with my Diztronic.

      I always used Diztronic. But for my Note2, I snagged a Body Glove TPU case. It’s amazing. Expensive, but worth it.

      • I had a bodyglove for my epic. Build it quickly fell apart after a few months. But it was nice while it lasted. Lets hope their build quality is better these days.
